Description

Electronic equipment

Technical Field

The application relates to the field of terminals, in particular to an electronic device for measuring pulse waves.

Background

Pulse waves are formed by the outward propagation of blood under pressure along arterial blood vessels caused by heart beating (vibration), and are one of the basic vital signs of the human body. The pulse rate and pulse rhythm of the pulse wave can be used for early warning of abnormal states of human bodies and evaluating the health states of the cardiovascular system.

Currently, pulse wave detection devices are mainly desktop devices and wrist-worn wearable devices (for example, smart watches or smart bracelets). The desk type equipment has the defects of single use scene, inconvenience in carrying and incapability of measuring at any time. When a user detects pulse waves by using a wrist-worn wearable device (for example, a wristwatch is illustrated), the user needs to rotate the wristwatch on the wrist, so that a protruding structure (i.e., a pressure sensor assembly) fixed on the back of the watch body (i.e., the side of the watch body contacting the wrist of the user when the user wears the wristwatch normally) is aligned with the radial artery or ulnar artery at the wrist, and the pressure applied to the wrist of the user is relatively high by pressing the watch body with a finger to measure the radial artery or ulnar artery. When the user wears the watch normally, this protruding structure can produce pressure to user's wrist, and its operation experience is all relatively poor with wearing the travelling comfort, and user experience is low.

Pulse waves are formed by the outward propagation of blood under pressure along arterial blood vessels caused by heart beating (vibration), and are one of the basic vital signs of the human body. The propagation speed of pulse wave depends on the physical and geometric properties of the propagation medium, such as elasticity of artery, size of lumen, density and viscosity of blood, and the like, and is closely related to the elasticity, caliber and thickness of arterial wall, so that the pulse wave image can be obtained by detecting at the position of the blood vessel with shallow body surface. The pulse rate and pulse rhythm of the pulse wave can be used for early warning of abnormal states of human bodies and evaluating health states of cardiovascular systems. For example, pulse wave velocity (pulse wave velocity, PWV) has a strong correlation with blood pressure and degree of elasticity of the vessel wall, and can be used for non-invasive measurement of continuous blood pressure and prediction of arteriosclerosis. Some parameter characteristics such as the maximum value, the average value, the median value, the pulse wave area, the K value, the frequency spectrum and the like of the main wave peak can be extracted from the pulse wave, and the pulse wave can be used for evaluating sub-health, visual fatigue and drowsiness states of human bodies, identifying emotion, cardiovascular diseases and the like. In addition, pulse waves are applied to the field of traditional Chinese medicine, three fingers for traditional Chinese medicine pulse diagnosis are used for lifting, pressing and searching three parts of radial artery of a human body, and the health state of the human body is judged by the information fed back by pulse fluctuation, so that the purpose of diagnosing the disease before symptoms of the specific disease do not appear can be achieved.

The pulse wave detection principle is as follows: the pressure sensor is arranged on the skin surface at the pulsation position, and under the action of certain pressing force, the pressure sensor senses the pulsation pressure signal and converts the pulsation pressure signal into an electric signal to be output, and the pulse wave can be obtained after the processing. Currently, pressure sensors are mainly classified into three working principles of piezoresistive type, pressure-capacitance type and piezoelectric type, wherein the piezoresistive type and the pressure-capacitance type can measure absolute pressure, and the piezoelectric type can only measure relative variation.

Currently, pulse wave detection devices are mainly desktop devices and wrist-worn wearable devices (for example, smart watches or smart bracelets). The desk type equipment has the defects of single use scene, inconvenience in portability and incapability of measuring at any time.

For a wrist-worn wearable device, fig. 1 is a schematic structural diagram of a wristwatch based on a pressure sensor for measuring pulse waves. As shown in a diagram a of fig. 1, it detects pulse waves at the radial artery or ulnar artery of a user by a protruding structure (which is a pressure sensor assembly) provided on the back surface of the watch body (i.e., the surface of the watch body that contacts the wrist of the user when the watch is worn normally, or the surface opposite to the display screen on the watch body), but there are the following problems: first: because the radial artery or the ulna is positioned on the inner side of the wrist of the user, and the back surface of the watch body is not contacted with the skin of the wrist of the user when the user wears the watch normally, as shown in the diagram b in fig. 1, when the user measures pulse waves, the user needs to rotate the watch on the wrist so that the back surface of the watch body is contacted with the skin of the wrist of the user (namely, the user needs to wear the watch reversely), and pressure is required to be applied to the protruding structure by hands to keep proper pressing force, the operation is troublesome, and the user cannot easily grasp the proper pressing force; second,: when the watch is worn normally, the protruding structure at the bottom of the watch can generate pressure on the wrist of a user, so that wearing comfort is affected; third,: each time a measurement is taken, the protruding structure needs to be accurately aligned with the location of the beat (e.g., radial or ulnar artery), and the user cannot easily find the location of the radial or ulnar artery. In summary, this approach requires the user to manually apply pressure to the protruding knot, which presents problems of alignment difficulties, poor operating experience and wearing comfort.

For wrist strap type wearable devices, the wrist is pressurized wholly or mostly by means of wrist strap locking or automatic pressurization of an air bag, so as to achieve the purpose of pressurizing at pulse pulsation (such as radial artery or ulnar artery). However, the applied pressure is determined by the wrist-strap wearable device in both modes, so that the user cannot actively adjust the applied pressure, and pain and discomfort are easy to occur due to different pain sensation thresholds of each user, so that the user measurement experience is poor.

In conclusion, the desk type pulse wave detection device is inconvenient to measure and cannot detect in real time at any time and any place. Based on the wearable equipment of wrist strap, there is the user to use the travelling comfort poor when using, and operation experience is relatively poor with wearing travelling comfort scheduling problem.

In view of this, the present application provides an electronic device that includes a display (e.g., a watch body 203), a wristband (e.g., a first wristband 201 and a second wristband 202) coupled to the display, a pressure sensor array 208 disposed on the wristband (e.g., the second wristband 202), and a first component 206 (e.g., wristband strap 206). Wherein the first component 206 is comprised of a first element 206a (e.g., a meter cuff body 206 a) and a second element 206b (e.g., a meter cuff head 206 b). The first part 206 is movably fitted over the first band 201 or the second band 202. After the user fastens the wristband about the wrist, the fastened wristband applies pressure to the first member 206. By the user moving the position of the first part 206 on the wrist strap, the first part 206 is caused to press the pressure sensor array 208 on the wrist strap, the pressure sensor array 208 is pressed against and contacts the pulse of the user (for example, radial artery or ulnar artery), and the pressure sensor array 208 is caused to measure the pulse of the user, thereby obtaining the pulse wave and displaying it on the display of the watch body 203. The pressure sensor is convenient to wear and measure, the pressure applied to the pressure sensor is controlled by a user, the use is convenient, and accurate and comfortable user measurement experience is brought for the instant detection of pressure pulse waves.

The electronic device provided by the present application is described below with reference to specific examples.

In the following examples, the electronic device will be described as an example of a smart watch, but this should not be any limitation on the embodiments of the present application, for example, in the embodiments of the present application, the electronic device may also be other types of electronic devices, including, for example: smart bracelets, or other wrist-wearable devices, etc. The embodiments of the application are not limited in this regard.

As shown in b of fig. 2, marks (i.e., third marks) for distinguishing different clasp holes are provided near the plurality of clasp holes 205 on the first wristband 201, respectively. For example, as shown in b of fig. 2, the identifier may be a number, etc., and the embodiment of the present application does not limit the specific form of the identifier on the plurality of fastening holes 205, as long as the identifier can distinguish between different fastening holes. When the user wears the wristwatch, the clasp 204 is inserted into one of the clasp holes 205, and the number of the clasp hole 205 is used to position the clasp 204.

The front surface of the first wristband 201 (i.e., the surface opposite to the surface of the first wristband 201 that contacts the skin of the user's wrist when the user wears the wristwatch) is provided with graduations, and in the embodiment of the present application, the back surface of the first wristband 201 is the surface of the first wristband 201 that contacts the skin of the user's wrist when the user wears the wristwatch.

After the user wears the watch, the first wristband 201 passes through the clasp 204 and wristband 206, and the graduations on the first wristband 201 are used to locate the position of the wristband 206 on the second wristband 202.

As shown in a diagram of fig. 2, a flexible substrate 207 is provided on the back surface of the second wristband 202 (i.e., the surface of the second wristband 202 that contacts the wrist of the user when the user wears the wristwatch), and a pressure sensor array 208 is fixed to the flexible substrate 207. Alternatively, the flexible substrate 207 may be laid on the entire area or a partial area of the back surface of the second band 202.

In embodiments of the present application, the back side of second wristband 202 (i.e., the side of second wristband 202 that contacts the user's wrist skin when the user wears the watch) may also be referred to as the first side of second wristband 202, and the front side of second wristband 202 (i.e., the side opposite the back side of second wristband 202) may also be referred to as the second side of second wristband 202. In other words, after the user wears the watch, the side of the second wristband 202 that the user can see is the second side of the second wristband 202, and the side of the second wristband 202 that the user cannot see is the first side of the second wristband 202.

Similarly, the back side of first wristband 201 (i.e., the side of first wristband 201 that contacts the user's wrist skin when the user wears the watch) may also be referred to as the first side of first wristband 201, and the front side of first wristband 201 (i.e., the side opposite the back side of first wristband 201) may also be referred to as the second side of first wristband 201. In other words, after the user wears the wristwatch, the side of the first band 201 that the user can see is the second side of the first band 201, and the side of the first band 201 that the user cannot see is the first side of the first band 201.

The flexible substrate 207 to which the pressure sensor array 208 is secured may be removably attached to the second wristband 202, or may be secured (e.g., by gluing, etc.) to the second wristband 202. An electrical lead 209 is provided on the flexible substrate 207 for transmitting pressure signals detected by the pressure sensor array 208 to the meter 203, so that a processor in the meter 203 processes the pressure signals to obtain pulse waves at the radial artery or ulnar artery of the user. The second wristband 202 is threaded through the case band 206 (i.e., the case band 206 is movably fitted over the second wristband 202), and after the second wristband 202 is threaded through the case band 206, one side of the case band 206 is positioned between the flexible base 207 and the second wristband 202, and the case band 206 is movable within a space defined by the second wristband 202 and the flexible base 207. After the user wears the watch clasp 204, the pressure generated by the second watchband 202 acts on the watch band 206, the band 206 presses the flexible substrate 207 under the action of the pressure, the flexible substrate 207 presses the flexible substrate 207 under the action of the pressure, the pressure sensor array 208 on the flexible substrate 207 contacts with the radial artery or the ulnar artery of the user, the pressure sensor array 208 measures the pulse of the radial artery or the ulnar artery of the user, a pressure signal is obtained, the pulse signal is transmitted to the watch body 203 through the electric wire 209 on the flexible substrate 208 for processing, the processor in the watch body 203 processes the pressure signal to obtain a pulse wave image, and further, some parameter characteristics (such as blood pressure, heart rate, arteriosclerosis risk index and the like) can be obtained from the pulse wave image, so that the obtained pulse wave image and the parameter characteristics can be displayed to the user on the display screen of the watch body 203.

In an embodiment of the application, the first component 206 may be a wristband clip 206 as shown in fig. 2. In the following examples, wristband tie 206 will be described as an example.

Optionally, as shown in a diagram of fig. 2, a flexible printed circuit board (flexible printed circuit board, FPC) connector 210 may be disposed between the flexible substrate 207 and the meter body 203, and the FPC connector 210 is configured to transmit the pressure signal measured by the pressure sensor array 208 to the meter body 203, so that the processor in the meter body 203 further processes the pressure signal.

For example: as one possible implementation is: the FPC connector 210 may be fixed to the meter body 203, and the electrical leads 209 and the meter body 203 are connected by the FPC connector 210, and the FPC connector 210 corresponds to one interface. During the removal and installation of the flexible substrate 207 from the second wristband 202, the FPC connector 210 may provide contacts or pins or the like for connection with the electrical leads 209, thereby enabling connection of the electrical leads 209 with the watch body 203.

As another possible implementation is: the FPC connector 210 may be fixed to the flexible board 207 and connected to the electrical leads 209, and the meter body 203 may be provided with an interface for connecting to the FPC connector 210, and the electrical leads 209 and the meter body 203 may be connected by the FPC connector 210. During the process of removing and mounting the flexible substrate 207 from the second wristband 202, the FPC connector 210 may provide pins or contacts or the like for connection with the bezel 203, thereby enabling connection of the electrical leads 209 with the bezel 203.

It should be understood that in other embodiments of the present application, the FPC connector may be replaced with other types of circuit interfaces, etc., and embodiments of the present application are not limited in this respect.

It should also be understood that fig. 2 is merely exemplary, and should not limit the structure of the smart watch according to the embodiment of the present application, for example, the scales on the first watchband 201 may be sequentially arranged from left to right, or the numbers of the clasp holes on the first watchband 201 may be sequentially arranged from left to right (the scales on the first watchband 210 are sequentially arranged from right to left as shown in the b-diagram in fig. 2), and the numbers of the clasp holes on the first watchband 201 may be sequentially arranged from right to left. The embodiments of the application are not limited in this regard.

Fig. 3 is a schematic structural diagram of a watch band 206 according to an embodiment of the present application, and as shown in fig. 3, in an embodiment of the present application, the watch band 206 is assembled by a band head 206b and a band body 206a, and one band body 206a may be assembled (or collocated) with band heads with different heights, respectively, to obtain a plurality of different band heads, so as to achieve the purpose of adjusting the pressure applied to the pressure sensor. In other words, different heights of the cuff heads correspond to different pressure values. Illustratively, as shown in fig. 3, the height of the gauge outfit 206b is denoted by γ, and for each gauge outfit, the height γ may be identified on the gauge outfit (i.e., the height of the gauge outfit 206b is indicated by the fourth identification) for user identification, and in embodiments of the present application, a plurality of gauge outfits of different heights may be provided, for example, the height of the gauge outfit may be 1mm, 2mm, 3mm, 4mm, 5mm, etc., respectively, and embodiments of the present application are not limited to the height of the plurality of gauge outfits.

It should also be appreciated that in embodiments of the present application, wristband tie 206 may be integrally formed, i.e., not assembled from case band body 206a and case band head 206b, where case band body 206a and case band head 206b are not removable, multiple case bands 206 may be prepared, with different band bands 206 corresponding to different case band head 206b heights.

In an embodiment of the present application, the first element 206a may be the watch band 206a shown in FIG. 3, and the second element 206b may be the watch band head 206b shown in FIG. 3. In the examples below, the meter cuff body 206a and the meter cuff head 206b are illustrated as examples. In the embodiment of the present application, the watch band may also be referred to as a watch clasp, a watch buckle, a watch band fixing ring, a moving ring, a watch band, or a band, which is not limited herein.

As shown in FIG. 3, the width of the meter cuff body 206a (or may also be referred to as the width of the meter cuff) is denoted as D3, and in some embodiments, the meter cuff body 206a width D3 is approximately 2 to 3 times the average diameter of the user's radial or ulnar artery blood vessel. For example, the width D3 of the meter cuff 206a may have a value of 7.5mm. It should be understood that the specific values for the width of the meter cuff 206a are not limiting in embodiments of the present application. The width of the meter cuff body 206a may be other values as long as the meter cuff body 206a has a width that is greater than the average diameter of the user's radial or ulnar artery blood vessel. The embodiments of the application are not limited in this regard.

As shown in FIG. 3, meter band 206 is assembled (mounted) from meter band head 206b and meter band body 206a, and meter band head 206b may be mounted to the side of meter band body 206a adjacent the wrist of the user. As shown in FIG. 3, the meter cuff head 206b is mounted on the underside of the meter cuff body 206a, with the underside of the meter cuff body 206a being closer to the wrist of the user than the upper side of the meter cuff body 206 a.

It should be understood that in other embodiments of the present application, the meter cuff head may also be mounted on the upper side of the meter cuff body, embodiments of the present application are not limited in this respect.

Fig. 4 is a schematic diagram showing a side view of the band 206 (assembled by the band head 206b and the band body 206 a), the pressure sensor array 208, and the flexible substrate 207 on the second band 202 in the configuration shown in fig. 2, and fig. 4 is a schematic diagram showing a case where the user measures pulse waves using the wristwatch. As shown in fig. 4, a pressure sensor array 208 is fixed on the flexible substrate 207, for example, the pressure sensor array 208 may be fixed on the flexible substrate 207 by means of gluing or the like, in which case an electrical wire 209 on the flexible substrate 207 may be in contact with the pressure sensor array 208, a pressure signal measured by the pressure sensor array 208 is transmitted to the electrical wire 209, and the pressure signal is transmitted to the meter body 203 through the electrical wire 209; alternatively, the connection between the pressure sensor array 208 and the flexible substrate 207 may be an electrical connection, in which case the electrical leads 209 may be disposed in any area of the flexible substrate 207, and not necessarily in contact with the pressure sensor array 208, and the pressure signal measured by the pressure sensor array 208 is transmitted to the flexible substrate 207, and the flexible substrate 207 transmits the pressure signal to the meter body 203 through the electrical leads 209.

In an embodiment of the present application, the placement location of the pressure sensor array 208 may be determined by data statistics. For example, the location of the radial or ulnar artery on the second wristband 202 or flexible substrate 207 may be counted when a plurality of users wear the watch to determine the location of the pressure sensor array 208 disposed on the second wristband 202 or flexible substrate 207. For example, for a second wristband 202 of 53mm length, the pressure sensor may be disposed on an area of flexible substrate 207 that is 3.1cm to 6.1cm from clasp 204.

In some embodiments, as shown in fig. 4, the flexible substrate 207 may be detachably connected to the second wristband 202 by a plurality of connection members 211, wherein any one of the connection members 211 may be detachably connected to the second wristband 202. For example, the connection member may be a buckle, etc., and embodiments of the present application are not limited herein. Before the flexible board 207 is fixed to the second band 202, the band 206 (assembled by the band head 206b and the band body 206 a) is fitted over the second band 202, and then the flexible board 207 is fixed to the second band 202 by the connecting member 211. The watch band 206 is movable in the space formed by the adjacent two connecting members 211. In other words, when the user moves the position of the band 206a on the second band 202 by hand, the movement range R of the band 206a is limited by the two connecting members 211 adjacent to each other on the left and right.

As shown in FIG. 4, the second wristband 202 passes through a case band 206a (i.e., the case band 206a is fitted over the second wristband 202), and in the example shown in FIG. 4, the case band head 206b is mounted on the upper side of the case band 206a (i.e., the case band head 206b is mounted on the side of the case band 206a adjacent to the user' S wrist surface skin S). The user may manually move the position of the watch band 206 (assembled from the watch band head 206b and the watch band body 206 a) on the second wristband 202 so that the band 206 may press against the pressure sensor array 208 on the flexible substrate 207. After the user fastens the second wristband 202, the pressure generated by the second wristband 202 acts on the upper side of the band body 206a, the upper side of the band body 206a transmits the pressure to the band head 206b, the band head 206b changes position under the action of the pressure (i.e., the band head 206b moves along the direction perpendicular to the second wristband 202), so that the band head 206b contacts and presses the flexible substrate 207, the flexible substrate 207 deforms under the action of the pressure (the flexible substrate 207 protrudes toward the side of the user 'S wrist surface skin S), so that the pressure sensor array 208 on the flexible substrate 207 contacts with the radial artery or ulnar artery of the user' S wrist surface skin S, and the pressure sensor array 208 can measure the pulse of the radial artery or ulnar artery of the user to obtain a pressure signal.

It should be understood that the distribution of the pressure sensor array 208 on the flexible substrate 207 in the embodiment of the present application should not be limited by the illustration of fig. 4. In other embodiments of the present application, the pressure sensor array 208 may be disposed at other locations on the flexible substrate 207 according to measurement needs, as long as the pressure sensor array 208 may contact the radial artery or ulnar artery at the wrist of the user during the measurement process, and embodiments of the present application are not limited herein.

Fig. 5 is a schematic block diagram showing a side view of a band strap 206, a pressure sensor array 208, and a flexible substrate 207 on the second band 202 in the configuration shown in fig. 2. Fig. 5 is a schematic diagram showing a case where the user measures the pulse wave without using the wristwatch, i.e., the user uses only the basic functions of the smart wristwatch. The structure shown in fig. 5 differs from the structure shown in fig. 4 in that: in the configuration shown in fig. 5, the gauge outfit 206b is mounted on the underside of the gauge outfit 206a (i.e., the gauge outfit 206b is mounted on the side of the gauge outfit 206a remote from the user 'S wrist surface skin S), while in the configuration shown in fig. 4, the gauge outfit 206b is mounted on the upper side of the gauge outfit 206a (i.e., the gauge outfit 206b is mounted on the side of the gauge outfit 206a near the user' S wrist surface skin S).

In the structure shown in fig. 5, after the user fastens the second band 202, the pressure generated by the second band 202 acts on the upper side of the band body 206a, so that the band head 206b will not be pressed by the band body 206a, in which case, since the band body 206a generates less pressure on the flexible substrate 207, the band body 206a generates less pressure on the wrist surface skin S of the user or does not generate pressure on the wrist surface skin S of the user, improving wearing comfort.

Alternatively, as another possible implementation, in the case where the user does not use the watch to measure the pulse wave, the user may remove the band head 206b from the band body 206a, that is, the band body 206a does not mount the band head 206b, and only the band body 206a is sleeved on the second band, that is, the band head 206b may not be included in the structure shown in fig. 5. This also improves wearing comfort and also prevents the band head 206b from falling off the band body 206a, preventing the band head from being lost. When the user measures the pulse wave using the wristwatch, the user can measure the pulse wave using the wristwatch by detaching the flexible substrate 207 from the second wristband 202 through the connecting member 211 between the flexible substrate 207 and the second wristband 202, then attaching the band head 206b to the side of the band body 206a near the user' S wrist surface skin S, and then fixing the flexible substrate 207 and the second wristband 202 through the connecting member, for example, as shown in fig. 4.

Alternatively, as yet another possible implementation, if the second band 202 and the case 203 are detachably connected, the user may remove the band strap 206 as a whole from the second band, without using the wristwatch to measure pulse waves. For example, the second band 202 may be detached from the watch body 203 as a whole, then the flexible substrate 207 may be detached from the second band 202 by the connecting member 211 between the flexible substrate 207 and the second band 202, then the band head 206b and the band body 206a may be removed from the second band 202, and finally the flexible substrate 207 may be connected to the second band 202 by the connecting member 211, and then the second band 202 may be connected to the watch body 203. When the user uses the wristwatch to measure pulse waves, the second wristband 202 is detached from the watch body 203, the flexible substrate 207 is detached from the second wristband 202 by the connecting member 211 between the flexible substrate 207 and the second wristband 202, the band 206 (assembled by the band head 206b and the band body 206 a) is then fitted over the second wristband 202, the flexible substrate 207 and the second wristband 202 are fixed by the connecting member 211, and finally the whole second wristband 202 is connected to the watch body 203, for example, as shown in fig. 4, so that the user uses the wristwatch to measure pulse waves.

Fig. 6 is a schematic diagram illustrating dimensions of the pressure sensor array 208 and the wristband 206 on the flexible substrate according to an embodiment of the present application, and as shown in fig. 6, the pressure sensor array 208 is composed of a plurality of pressure sensor units 208 a. The specific shape of the pressure sensor unit 208a is not limited in the embodiment of the present application, and may be, for example, a circular shape as shown in fig. 6, or may be a rectangular shape or other shapes.

Optionally, in an embodiment of the present application, the size of each pressure sensor unit 208a is less than or equal to a preset threshold, for example: the size (e.g., diameter, side length, diagonal length, etc.) of each pressure sensor unit 208a is approximately equal to the average diameter of radial/ulnar artery vessel B; alternatively, the size of each pressure sensor unit 208a may also be smaller than the average diameter of the radial artery/ulnar artery B, for example, the size of each pressure sensor unit 208a may be one third or one half, etc. of the average diameter of the radial artery/ulnar artery B. The embodiments of the application are not limited in this regard. For example, as shown in fig. 6, the pressure sensor unit 208a has a circular shape with the same diameter as the average diameter of the radial artery or the ulnar artery blood vessel.

In some embodiments, the plurality of pressure sensor units 208a may be arranged in a single row or in a plurality of rows (e.g., two rows as shown in fig. 6). The embodiments of the application are not limited in this regard.

Fig. 7 is a schematic view showing an example of a user wearing the wristwatch shown in fig. 2 to 6 to measure pulse waves at the radial artery, and the band 206 (assembled by the band head 206b and the band body 206 a) is movable within a movement range R of the band 206 shown in fig. 7. After the user wears the watch, the clasp 204 on the second watchband 202 is clasped into one of the clasp holes on the first watchband 201, so that the second watchband 202 and the first watchband 201 are clasped. Optionally, the remaining portion of the first watchband 201 after passing through the clasp may also pass through the clasp 206, so that free swinging of the remaining first watchband 201 after passing through the clasp 204 may be prevented, thereby implementing bundling of the remaining first watchband 201 after passing through the clasp 204, and improving wearing experience of the user.

As shown in fig. 7, when the second wristband 202 and the first wristband 201 are fastened, the second wristband 202 generates pressure in a direction toward the skin S of the wrist of the user on the cuff 206, the pressure is applied to the cuff 206b by the cuff 206a (the cuff 206b is mounted on a side of the cuff 206a near the skin S of the wrist surface of the user), so that the position of the cuff 206b is changed, the flexible substrate 207 is contacted and pressed, the flexible substrate 207 is deformed by the pressure (the flexible substrate 207 is protruded toward the side of the skin S of the wrist surface of the user), so that the pressure sensor array 208 on the flexible substrate 207 contacts the skin S at the radial artery T of the wrist of the user, and applies pressure to the radial artery T of the wrist of the user, and the pressure sensor array 208 can measure the pulse of the radial artery T of the user to obtain a pressure signal. In determining the position of the meter band 206, the user may manually move the meter band 206 within the range of movement R of the wristband band 206 such that pressure generated by the meter band head 206b acts on the pressure sensor array 208 at the radial artery T of the user's wrist, i.e., the position of pressure applied to the pressure sensor array 208 may be changed by moving the meter band 206.

The pressure signal measured by the pressure sensor array 208 is transmitted to the FPC connector 210 through the electrical leads 209 on the flexible substrate 207, and the FPC connector 210 transmits the pressure signal to the meter body 203, so that the processor in the meter body 203 processes the pressure signal to obtain a waveform chart of the pulse wave. Further, some parameter characteristics (for example, blood pressure, heart rate, arteriosclerosis risk index, etc.) can be obtained from the pulse wave image, so that the obtained pulse wave image and the parameter characteristics can be displayed to the user on the display of the watch 203.

Fig. 8 is a schematic diagram showing an example of a user wearing the wristwatch normally without starting the measurement of pulse waves at the radial artery. The difference from fig. 7 is that shown in fig. 8: in the configuration shown in FIG. 7, the meter cuff head 206b is mounted to the side of the meter cuff body 206a adjacent to the user' S wrist surface skin S. In the structure shown in fig. 8, the band head 206b is mounted on the side of the band body 206a away from the skin S of the user 'S wrist surface, and when the second wristband 202 and the first wristband 201 are fastened, the second wristband 202 generates pressure on the band 206 in the direction toward the skin S of the user' S wrist, which does not act on the band head 206b, in which case the band body 206a may not contact with the flexible substrate 207 and press the flexible substrate 207, or may contact with the flexible substrate 207 and press the flexible substrate 207. In the case where the meter cuff 206a is in contact with the flexible substrate 207 and presses the flexible substrate 207, the pressure sensor array 208 on the flexible substrate 207 is also in contact with the radial artery T at the wrist of the user, but since the meter cuff 206a exerts less pressure on the flexible substrate 207. Thus, when the user does not use the watch to measure pulse waves, that is, when the watch is worn normally, the watch band head 206b is arranged on one side of the watch band body 206a far away from the surface skin S of the wrist of the user, and the watch band body 206a generates smaller pressure on the wrist of the user or does not generate pressure on the wrist of the user, so that wearing comfort is improved.

Alternatively, as another possible implementation, the user may remove the cuff head 206b from the cuff body 206a when the user is wearing the watch normally without initiating the measurement of the pulse wave at the radial artery, i.e., in the example shown in fig. 8, the cuff head 206b may not be included.

In some embodiments of the application, for example, in the example shown in FIG. 7, a user may use meter cuff heads 206b of different heights to vary or adjust the amount of pressure applied to pressure sensor array 208. For example, the higher the gauge cuff 206b used, the greater the pressure exerted on the pressure sensor array 208; alternatively, the amount of pressure applied to the pressure sensor array 208 may also be adjusted by changing the position of the clasp 204 that snaps into the clasp hole 205 on the first wristband 201, e.g., the tighter the clasp of the second wristband 202 and the first wristband 201, i.e., the greater the number of clasp 204 that snaps into clasp hole 205 on the first wristband, the greater the pressure applied to the pressure sensor array 208.

In some embodiments of the present application, the user can determine the position of the clasp, the position of the band and the height of the band head when the pressure signal quality reaches the requirement during the measurement according to the pressure signal quality fed back by the watch during the process of wearing the watch to measure the pulse wave.

For example, as shown in the example of fig. 7, the processor in the gauge body 203 may obtain the pressure signal detected by the pressure sensor array 208 in real time, and determine whether the pressure signal meets the measurement requirement, and if the pressure signal does not meet the measurement requirement, the user may change the pressure applied to the pressure sensor array by at least one of changing the position where the gauge button 204 is engaged, moving the gauge band 206, or replacing the gauge band head 206b at another height, so that the pressure signal does not meet the measurement requirement. When the pressure signal meets the measurement requirement, the watch can prompt that the quality of the pressure signal reaches the standard through modes such as sound, characters and the like, and in this case, the user can record and store the height of the used meter hoop head 206b, the position of the meter hoop body 206a and the position of the meter buckle 204, so that when the user measures pulse waves by using the watch next time, the parameters are prompted to the user, the user can wear the watch according to the parameters, use the meter hoop head 206b with the corresponding height and move the meter hoop body 206a to the corresponding position to start measurement, the complexity of the operation when the user performs measurement is greatly reduced, the operation flow is simplified, and the user experience is further improved.

In some embodiments, when the user wears the watch to measure pulse waves and the pressure signal meets the measurement requirements, the user may record the height γ of the band head 206b used, the position α at which the clasp 204 on the second wristband 202 snaps into the first wristband 201, and the position β of the band 206 on the first wristband. For example, the value of α may be the number N of the clasp 204 on the second wristband 202 that snaps into the clasp hole 205 of the first wristband 201, and the value of β may be the scale value S of the wristband clip 206 on the first wristband 201.

Alternatively, in some embodiments of the present application, the height γ of the gauge outfit 206b may be replaced by the gauge outfit number, where the gauge outfit 206b with different numbers corresponds to different heights, and the gauge outfit 206b number may be identified on the gauge outfit 206b for easy user identification.

For example, fig. 9 is a schematic diagram showing the positions of the clasp and band when the user wears the wristwatch to measure pulse wave and the pressure signal reaches the measurement requirement. As shown in fig. 9, the position β of the band 206 is 7.2, the number of the band hole 205 where the band 204 is fitted into the first band 201 is 5, that is, the value of α is 5, and if the height γ of the band head 206b is 2mm, the values of the height γ of the band head 206b, the position β of the band 206, and the position α of the band 204 can be obtained. Wherein the height γ of the band head 206b and the position α of the clasp 204 may be used to characterize the amount of pressure exerted on the pressure sensor array 208, and the position α of the clasp 204 and the position β of the band 206 may be used to characterize the position of the user's radial or ulnar artery. The user may record the values of the height gamma of the band head 206b, the position beta of the band 206, and the position alpha of the clasp 204 and store these three values in the watch.

When the user measures the pulse wave at the radial artery or the ulnar artery using the wristwatch next time, the user can use the cuff head 206b having the same height as the recorded one, attach the cuff head 206b to the cuff body 206a, assemble the cuff 206, fit the cuff 206 over the second wristband 202, and then fix the flexible substrate 207 to the second wristband 202 via the connecting member 211. Thereafter, the user engages the clasp 204 on the second wristband 202 into the corresponding clasp hole 205 according to the recorded position α of the clasp 204, and moves the clasp 206 to the corresponding position according to the recorded position β of the clasp 206, for example, as shown in fig. 7, so that measurement can be started. If the pressure signal at the time of measurement does not meet the measurement requirement, the pressure may be adjusted by fine-tuning the position of the meter band 206 on the second wristband 202, and if the pressure signal does not meet the measurement requirement after an attempt is made at all possible positions of the meter band 206 (e.g., at all positions within the wristband movement range R), the user may change the position of the snap-in of the meter snap 204 (i.e., snap the meter snap 204 into the other numbered meter snap hole 205) to make the attempt. If the pressure signal of the clasp 204 in the appropriate plurality of clasp holes 205 (i.e., the appropriate plurality of clasp holes based on the user's wrist dimension and reasonable tightness when wearing the watch) does not meet the measurement requirement, the user may replace the clasp heads 206b of other heights to try until the pressure signal meets the measurement requirement. In this case, the user can re-record and save in the watch the new value of the height γ of the band head 206b, the position β of the band 206 or the position α of the clasp 204, i.e. the user can update the value of the height γ of the band head 206b, the position β of the band 206 or the position α of the clasp 204 saved in the watch.

Fig. 10 is a schematic structural diagram of another example of a smart watch provided by the present application. The schematic structural diagram of the back side (i.e., the side opposite to the display screen on the watch body) of the smart watch shown in fig. 10 is a schematic structural diagram of the front side (i.e., the side on which the display screen on the watch body) of the smart watch shown in fig. 10. The difference from the smart watch shown in fig. 2 is that the band strap 206 shown in fig. 10 is movably fitted on the first band 201, and the band strap 206 can be freely moved on the first band 201. While the wristband strand 206 shown in fig. 2 is movably attached to the second wristband 202, the strand can only move within the space defined by the adjacent two attachment members 211. The structure of the watch band 206 is the same as that of the watch band shown in fig. 3, and the detailed description will refer to the description of fig. 3, and for brevity, the description will not be repeated here.

As shown in a diagram in fig. 10, a flexible substrate 207 is provided on the back surface of the second watchband 202, a pressure sensor array 208 is fixed on the flexible substrate 207, an electric wire 209 is provided on the flexible substrate, an FPC connector 210 is provided between the flexible substrate 207 and the watch body 203, the electric wire 209 on the flexible substrate 207 is used for transmitting a pressure signal detected by the pressure sensor array 208 to the FPC connector 210, and the FPC connector 210 is used for transmitting the pressure signal into the watch body 203, so that a processor in the watch body 203 further processes the pressure signal.

As shown in b of fig. 10, a position mark point (i.e., a first mark) D of the pressure sensor array 208 is displayed on the front surface of the second wristband, and the first mark is used to indicate to the user the boundary of the setting area of the pressure sensor array 208, and the user can determine the distribution of the pressure sensor array 208 on the back surface of the second wristband according to the position mark point D of the pressure sensor array, so that the position of the wristband on the first wristband 201 can be moved, and the pressure generated by the wristband 206 acts on the pressure sensor array 208.

As shown in a diagram in fig. 10, a buckle 212 is disposed at one end of the first watchband 201 away from the watch body 203, and as shown in b diagram in fig. 10, a plurality of clamping grooves 213 are formed on the front surface of the second watchband, and the clamping grooves 213 do not penetrate the second watchband, i.e. the depth of the clamping grooves 213 is smaller than the thickness of the second watchband 202. The clamping groove 213 is provided with a clamping groove number E (i.e. a second identifier), and the buckle 212 and any clamping groove 213 can realize detachable buckle connection. The number E on the card slot is used to locate the position of the catch 212 and card slot 213 when the catch is connected. Optionally, a clasp 212 on the first wristband 201 may also prevent the case band 206 from falling off the first wristband 201.

Alternatively, as a possible implementation, in the example shown in fig. 10, in the case where the user fastens the first wristband 201 and the second wristband 202 to the wrist through the clasp 212 and the slot 213, the first wristband 201 and the second wristband 202 may not need to be fastened to the wrist of the user through the clasp 204 and the clasp hole 205. That is, in the structure shown in fig. 10, the button 204, the button hole 205, and the button hole number N (i.e., the third symbol) may not be included.

As shown in b of fig. 10, when the user wears the wristwatch, the clasp 204 is inserted into the clasp hole 205, and the clasp hole number N is used to position the clasp 204. The first watchband 201 is provided with scales, when a user wears the watch, the first watchband 201 passes through the watch buckle 204, then the watch strap 206 is sleeved on the rest part of the first watchband 201 after passing through the watch buckle 204 (namely, the watch strap 206 is sleeved on the rest first watchband 201 after passing through the watch buckle 204), and finally the buckle 210 on the first watchband 201 and one clamping groove 213 on the second watchband 202 are connected and fastened through the buckle. In other words, in the structure shown in fig. 10, the band strap 206 is only fitted over the first band 201, not over the second band 202, during the measurement of pulse waves by the user wearing the wristwatch. In the structure shown in fig. 2, the band strap 206 needs to be fitted over the second band 202 or may be fitted over the second band 202 and the first band 201 during the pulse wave measurement when the user wears the wristwatch.

In the structure shown in fig. 10, the form of the pressure sensor array 208 and the size and arrangement of the plurality of pressure sensor units are similar to those shown in fig. 6, and a specific description will refer to the description of fig. 6, and for brevity, will not be repeated here.

In the example shown in fig. 10, as a possible implementation manner, a flexible substrate 207 is disposed on the back surface of the second watchband 202, and a pressure sensor array 208 is fixed on the flexible substrate 207, for example, the pressure sensor array 208 may be adhered on the flexible substrate 207, and a detachable connection may be formed between the flexible substrate 207 on which the pressure sensor array 208 is fixed and the second watchband 202, for example, fig. 11 is a schematic block diagram illustrating an example of a side view of the pressure sensor on the second watchband and the flexible substrate, and as shown in fig. 11, the flexible substrate 207 may be detachably connected between a plurality of connection parts 211 and the second watchband 202, where any one of the connection parts 211 may be detachably connected with the second watchband 202. This may facilitate replacement of the flexible substrate.

In the example shown in fig. 10, as another possible implementation manner, for example, fig. 12 shows a schematic structure diagram of a side view of the pressure sensor on the second surface tape and the flexible substrate, as shown in fig. 12, the pressure sensor array 208 is fixed on the flexible substrate 207, and for example, the pressure sensor array 208 may be fixed on the flexible substrate 207 by gluing or the like. The flexible base 207 and the second wristband 202 may be fixedly connected by gluing or the like.

Fig. 13 is a schematic diagram showing an example of a pulse wave measurement at the radial artery of the wristwatch shown in fig. 10 when the user wears the wristwatch shown in fig. 13, when the user wears the wristwatch, the clasp 205 on the second watchband 202 is clasped into one of the clasp holes on the first watchband 201, then the clasp 206 is sleeved on the remaining portion of the first watchband 201 after passing through the clasp 204 (i.e. the clasp 206 is sleeved on the remaining first watchband 201 after the clasp 204), and then the clasp 212 on the first watchband 201 is in snap connection with the clasp slot 213 on the second watchband 202. When the clasp 212 on the first wristband 201 is fastened to the clasp slot 213 on the second wristband 202 by the clasp connection, the first wristband 201 generates pressure towards the skin S of the user 'S wrist on the cuff 206 (assembled by the cuff 206b and the cuff 206 a), the pressure acts on the cuff 206b through the cuff 206a (the cuff 206b is mounted on the side of the cuff 206a near the user' S wrist) so that the position of the cuff 206b changes and presses the second wristband 202, the second wristband 202 protrudes (i.e. deforms) towards the skin S of the user 'S wrist under the pressure, and the flexible substrate 207 on the second wristband 202 deforms accordingly so that the pressure sensor array 208 on the flexible substrate 207 contacts the skin S of the user' S wrist radial artery T and applies pressure to the radial artery T of the user 'S wrist, so that the pressure sensor array 208 can measure the pulse of the user' S radial artery T and obtain a pressure signal. In determining the position of the watch band 206, the user may manually move the watch band 206 back and forth within the band movement range R marked on the second band 202 such that the pressure generated by the band head 206b acts on the pressure sensor array 208 at the user's wrist radial artery T.

The pressure signal measured by the pressure sensor array 208 is transmitted to the FPC connector 210 through the electrical lead 209 on the flexible substrate 207, and the FPC connector 210 transmits the pressure signal to the meter body 203, so that the processor in the meter body 203 processes the pressure signal to obtain a waveform chart of a pulse wave, further, some parameter characteristics (such as blood pressure, heart rate, arteriosclerosis risk index and the like) can be obtained from the pulse wave image, and thus the obtained pulse wave image and the parameter characteristics can be displayed to a user on a display of the meter body.

When the user is wearing the watch normally without measuring the pulse wave, as a possible implementation, the user may remove the watch band 206 from the first wristband 201 (i.e., remove the watch band body 206a and the watch band head 206b from the first wristband 201), and then put the watch band 206 around the first wristband 201 when the pulse wave is to be measured.

As another possible implementation, when the user wears the watch normally without measuring the pulse wave, for example, as shown in fig. 14, fig. 14 is a schematic diagram showing an example that the user wears the watch normally without starting to measure the pulse wave at the radial artery. The difference from fig. 13 shown in fig. 14 is that: in fig. 13, the watch band head 206b is mounted on the side of the watch band body 206a near the wrist surface skin S, while in fig. 14, the watch band head 206b is mounted on the side of the watch band body 206a away from the user wrist surface skin S. That is, when the wristwatch is worn normally, the band head 206b is mounted on the side of the band body 206a away from the wrist of the user, and the band body 206a generates little or no pressure on the wrist of the user, thereby improving wearing comfort.

As yet another possible implementation, the user may also detach the cuff head 206b from the cuff body 206a when the user is wearing the watch normally without measuring the pulse wave.

In some embodiments of the present application, for example, in the example shown in FIG. 13, a user may use meter cuff heads of different heights to vary or adjust the amount of pressure applied to the pressure sensor array. For example, the higher the gauge strip head used, the greater the pressure exerted on the pressure sensor array.

In the example shown in fig. 13, the user may determine the position of the clasp 204, the position of the clasp 212, the position of the band 206 and the height of the band head 206b when the pressure signal quality reaches the requirement according to the pressure signal quality fed back by the wristwatch while wearing the wristwatch to measure the pulse wave. For example, when the user wears the wristwatch to measure the pulse wave and the pressure signal reaches the measurement requirement, the user can record the height γ of the band head 206b used (i.e., the height of the band head 206 b), the position α of the clasp 204 on the second band 202 to clasp into the clasp hole 205 on the first band 201 (i.e., the position parameter of the clasp 204), the position β of the band 206 on the first band 201 (i.e., the position of the band 206), and the position θ of the clasp 212 on the first band 201 to clasp into the clasp slot 213 on the second band 202 (i.e., the position of the clasp 212), and store these parameters in the wristwatch. The value of α may be the number N of the clasp 204 on the second wristband 202 that is locked into the clasp hole 205 of the first wristband 201, the value of β may be the scale value S of the wristband clip 206 on the first wristband 201, and the value of θ may be the number E of the clasp 212 on the first wristband 201 that is locked into the clasp slot 213 on the second wristband 202.

Where the height γ of the band head 206b and the position θ of the clasp 212 may be used to characterize the amount of pressure exerted on the pressure sensor array 208, the position α of the clasp 204 and the position β of the band 206 may be used to characterize the position of the user's radial or ulnar artery. Therefore, when the user measures the pulse wave by using the watch next time, the parameters are prompted to the user, the user can wear the watch according to the parameters, the watch hoop head with the corresponding height is used, and the watch hoop body is moved to the corresponding position, so that measurement can be started, the complexity of operation when the user measures is greatly reduced, the operation flow is simplified, and the user experience is further improved. The user can update the height γ of the band head, the position β of the band, the position α of the clasp, or the position θ of the clasp stored in the wristwatch.

An exemplary flow of measuring pulse waves of the user will be described below taking the user wearing the wristwatch shown in fig. 2 as an example.

Before the user measures the pulse wave with the wristwatch for the first time, with the wristwatch shown in fig. 2, before the user wears the wristwatch, it is necessary to separate the second wristband 202 and the flexible substrate 207 by the connection member 211, and then mount the band head 206b on the side of the band body 206a facing (or near) the user wrist surface skin S, i.e., mount the band head 206b on the side of the band body 206a facing (or near) the pressure sensor array 208. Optionally, in some embodiments, indicia may also be present on the second wristband 202 for marking the location of the pressure sensor array 208, and based on these indicia, the user may move the case band 206 within the corresponding location area and mount the case band head 206b on the case band body 206a, and then mount the second wristband 202 and flexible substrate 207 together via the attachment component 211. Alternatively, in other embodiments, for example, as shown in fig. 4, since the watch band 206 can only move along the second band 202 within the movement range R formed by the two adjacent connecting members 211, the space formed by the two adjacent connecting members 211 can be identified on the second band 202, and different locations corresponding to different spaces, for example, space 1 corresponds to the radial artery and space 2 corresponds to the ulnar artery, in which case, the pressure sensor array can be provided on the flexible substrate 207 in both the region corresponding to space 1 and the region corresponding to space 2. The user can separate the second wristband 202 from the flexible substrate 207 by the connecting part 211 according to the measurement requirement, then mount the band body 206a in the corresponding space of the second wristband 202, mount the band head 206b on the side of the band body 206a near the skin S of the wrist surface of the user, mount the second wristband 202 and the flexible substrate 207 together by the connecting part 211, and finally fasten the second wristband 202 and the first wristband 201.

After the user wears the watch, fig. 15 is an exemplary diagram showing a display interface on the watch when the user measures the pulse wave by using the watch for the first time, where the watch and the user's mobile phone may be connected (paired) through bluetooth, the account of the watch may be the account of the mobile phone, and it should be understood that, in other embodiments of the present application, the watch may also be connected to the user's mobile phone through wireless fidelity (wireless-fidelity,) Connection by near field communication (near field communication, NFC), etc., embodiments of the application are not limited in this regard.

As shown in a diagram a in fig. 15, a "pulse wave measurement" control 1501 is displayed on the main interface of the wristwatch, and detected items are displayed on the control 1501, including, for example: heart rate, blood pressure, heart rhythm, etc. Where heart rate refers to the number of beats per minute of the heart. Heart rhythm refers to the rhythm of the heart, e.g., the heart rhythm of a normal person is typically sinus rhythm. After the user clicks the "pulse wave measurement" control 1501, the display interface of the watch may jump to the interface shown in b diagram in fig. 15, and since the user measures the pulse wave with the watch for the first time, in the interface shown in b diagram in fig. 15, a prompt box 1502 is displayed for prompting the user: please move the watchband hoop position, wait 3s after each movement, and stop moving after hearing the beeping. I.e., the user is prompted to move the meter band such that the pressure sensor can pressurize the user's radial or ulnar artery.

In the process of moving the band 206 by hand by the user, in the example shown in fig. 7, the second band 202 generates pressure in the direction of the wrist skin S of the user on the band 206 by the band 206a acting on the band head 206b (the band head 206b is mounted on the side of the band 206a near the wrist surface skin S of the user) so that the band head 206b moves and contacts (presses) the flexible substrate 207, and the flexible substrate 207 moves under the action of the pressure so that the pressure sensor array 208 on the flexible substrate 207 contacts the skin at the wrist radial artery T of the user and applies pressure to the skin at the wrist radial artery T of the user, so that the pressure sensor array 208 can measure the pressure signal.

During movement of the watch band 206 by the user, in the example shown in fig. 13, the first wristband 201 applies pressure to the watch band 206 in the direction of the user ' S wrist skin S, the pressure being applied to the watch band head 206b by the watch band body 206a (the watch band head 206b is mounted on the side of the watch band body 206a near the user ' S wrist surface skin S) so that the watch band head 206b contacts and presses the second wristband 202, the side of the second wristband 202 facing the user ' S wrist surface skin S is convex under the pressure, the flexible substrate 207 on the second wristband 202 is deformed accordingly, the pressure sensor array 208 on the flexible substrate 207 contacts the skin at the user ' S wrist radial artery T, and applies pressure to the skin at the user ' S wrist radial artery T, so that the pressure sensor array 208 can measure the pressure signal.

The pressure signal measured by the pressure sensor array 208 is transmitted to the FPC connector 210 through the electrical lead 209 on the flexible substrate 207, the FPC connector 210 transmits the pressure signal to the meter body 203, the processor in the meter body 203 processes the pressure signal to determine whether the pressure meets the measurement requirement, and in the case that the pressure signal meets the measurement requirement, that is, the pressure sensor array 208 on the flexible substrate 207 contacts with the radial artery or ulnar artery at the wrist of the user and applies pressure to the radial artery at the wrist of the user, the watch can prompt the user in a sound (e.g. beep), vibration, or text mode, etc.: the pressure signal has reached the standard, stopping moving the meter band 206.

For example, after the watch produces a beep, the user may stop moving the watch band 206.

Alternatively, after the user moves the watch band 206 to a position where the pressure signal meets the standard, the position of the first band 201 or the second band 202 of the watch band 206 may be fixed. For example, a chute along the direction of the first wristband 201 or the second wristband 202 may be provided in the case band 206a, and a protrusion may be provided on the second wristband 202 or the first wristband 201 (or a protrusion may be provided on the case band 206a, and a chute may be provided on the first wristband 201 or the second wristband 202), and the protrusion may be caught in the chute and may have a friction with the inner wall of the chute. During movement of the watch band 206 by the user, this friction force needs to be overcome to move the band 206 over the first band 201 or the second band 202. After the watch band 206 is moved to a position where the pressure signal is up to standard, the friction force can fix the position of the watch band 206 on the first band 201 or the second band 202, thereby preventing the movement of the watch band 206 during measurement.

Alternatively, other securing means may be used to secure the position of the watch band 206 on the second wristband 202 or on the first wristband 201 in embodiments of the application. Embodiments of the present application are not limited to a particular manner of securing the position of the first wristband 201 or the second wristband 202 to the watch band 206.

After the watch has beeped, the user stops moving the watch band 206. The watch begins to measure the pulse wave of the radial or ulnar artery contact at the wrist of the user. The display interface of the wristwatch can be changed from the interface shown in b in fig. 15 to the interface shown in c in fig. 15, and a prompt box 1503 and a waveform diagram 1504 of the pulse wave are displayed as the interface shown in c in fig. 15. The prompt box 1503 is used to prompt the user: the semi-fist is kept in the detection process and the arm is still, namely, the user is prompted to keep the correct posture in the measurement process, so that the accuracy of the measurement result can be improved. The processor in the watch body 203 can process the pressure signal measured by the pressure sensor array 208 in real time to obtain a waveform chart of the pulse wave, and the waveform chart is displayed to the user in real time in the display screen of the watch. After the measurement is finished, the display interface of the watch can jump from the interface shown in the c diagram in fig. 15 to the interface shown in the d diagram in fig. 15, and a prompt box 1505, a click view waveform diagram control 1506, a prompt box 1507 and a click input wearing parameter control 1508 are displayed as the interface shown in the d diagram in fig. 15.

The prompt box 1505 is used for prompting the user to finish detection, if the user needs to view the waveform diagram of the final pulse wave, the user can click the "click view waveform diagram" control 1506, and after clicking, the waveform diagram of the final pulse wave can be displayed to the user on the display screen of the watch. The waveform of the pulse wave is obtained by processing (e.g., differential amplifying, filtering, etc.) the pressure signal measured by the pressure sensor array 208 by the processor in the watch 203. Further, analysis of the pulse wave waveform graph may extract results of some measurement indexes from the pulse wave waveform graph, including, for example: blood pressure value, heart rate condition, risk of arteriosclerosis, etc.), prompt box 1507 is used to prompt the user for the results of these measurement metrics for the user to view. Clicking on the input wearing parameters control 1508 is used to prompt the user to input wearing parameters and save them for the next pulse wave measurement. After the user clicks the "click input wear parameters" control 1508, the display interface of the watch may jump from the interface shown in d-diagram in fig. 15 to the interface shown in e-diagram in fig. 15, where the prompt box 1509, the prompt 1510, and the "save" control 1511 are displayed. The prompt box 1509 prompts the user to input the position of the clasp 204, the position of the band 206, and the height of the band head 206b used.

It should be understood that the interface shown in fig. 15 e is an interface displayed when the user wears the wristwatch shown in fig. 2 to perform measurement, and if the user wears the wristwatch shown in fig. 10 to perform measurement, the prompt box 1509 may prompt the user to input the position of the buckle 212 (i.e. the number of the buckle 212 on the first watchband 201 that is buckled into the slot 213 on the second watchband 202) and save the position parameter of the buckle 212.

In some embodiments, the position α of the clasp 204 may be the number N of the clasp 204 on the second wristband 202 that clasps into the clasp aperture 205 on the first wristband 201, the position β of the clasp 206 may be the scale value S of the clasp 206 on a wristband 201, and the height γ of the clasp head 206b may be obtained from the indicia on the clasp head 206 b. The prompt 1510 is used to prompt the user for the position parameters of the clasp 204 and the read position of the band 206, so that the user can correctly determine the clasp position α and the band position β. The user obtains the number N of the gauge hole 205, the position β of the gauge band 206 on a watchband 201, and the height γ of the gauge band head 206b when the pressure signal reaches the measurement requirement according to the prompt information, and then inputs the values of these three parameters into the prompt box 1509. After the user outputs the values of these three parameters, clicking on the "save" control 1511, the watch can save these parameters for subsequent measurement by the user.

In some embodiments, the wristwatch, while maintaining these parameters, may be connected to the current cell phone bluetooth account (or bluetooth address) of the wristwatch, or to the current logged-in account of the wristwatch (e.g., the current logged-in account of the wristwatch is the user's cell phone), the current cell phone bluetooth account of the wristwatchAnd correspondingly storing the account number. For example, table 1 stores for a wristwatch one possibility of the clasp position, the band clasp position and the height of the band head usedIs realized by the method.

TABLE 1

As shown in table 1, after the user finishes measuring the pulse wave by using the watch for the first time, the watch can store three parameters of the clasp position alpha, the watchband clasp position beta and the height of the used clasp head gamma, and the three parameters are used for measuring the Bluetooth account number (address) connected with the watch, the user account number logged in with the watch and the watch connected with the watchAt least one of the account numbers. Watch connected with Bluetooth account number (address), user account number logged in by watch, watch connected +.>The account number can be used for representing the identity of the user, namely, the three parameters are corresponding to the identity of the user, so that the identity of the user can be conveniently identified in the follow-up measurement.

It should be understood that table 1 is merely exemplary, and should not be limited to the specific form of the watch preservation clasp position, band clasp position, and height of the band clasp head used in the embodiments of the present application, and in other embodiments of the present application, the watch may also preserve these three parameters in other ways, so long as the three parameters may be correlated to the identity of the user during preservation. The embodiments of the application are not limited in this regard.

For example, fig. 16 is a schematic diagram illustrating an interface displayed on a wristwatch when a user does not measure pulse waves by using the wristwatch shown in fig. 2 for the first time, and in the example shown in fig. 16, the wristwatch and the user's mobile phone are connected (paired) through bluetooth. As shown in a diagram a in fig. 16, a "pulse wave measurement" control 1601 is displayed on the main interface of the watch, and detected items are displayed on the control 1601, including, for example: heart rate, blood pressure, heart rhythm, etc. After the user clicks the "pulse wave measurement" control 1601, a processor in the watch may determine whether the bluetooth account currently connected to the watch (or bluetooth address) is in the saved information, i.e., whether the bluetooth account is included in at least one previously saved bluetooth account paired with the watch. If so, it is determined that the user is not using the watch for the first time to make a pulse wave measurement. If it is not, for example, assumed that another user performs measurement using the watch of the user, the watch needs to be paired with the mobile phone of the other user, for example, the watch is connected to the bluetooth account of the mobile phone of the other user, in which case, the processor in the watch may determine that the bluetooth account currently paired with the watch is not in the stored bluetooth account information, and determine that the other user uses the watch for pulse wave measurement for the first time.

It should be understood that in the embodiment of the present application, in addition to determining whether the user is the first measurement by using the bluetooth account currently paired with the wristwatch, the user account currently logged in by the wristwatch or the mobile phone currently connected to the wristwatch may be usedAccount numbers, etc. to determine if the user is the first measurement. The embodiments of the application are not limited in this regard.

In some embodiments, if it is determined that a certain user uses the watch for pulse wave measurement for the first time, the measurement process may refer to the description of fig. 15, and for brevity, a description is omitted here.

In some embodiments, if it is determined that a user does not use the wristwatch for the first time to measure pulse wave, the display interface of the wristwatch may jump to the interface shown in fig. 16 b, and since the user does not use the wristwatch for the first time to measure pulse wave, as shown in fig. 16 b, a prompt box 1602 and a prompt message 1603 are displayed, where the prompt box 1602 is used to prompt the user of the clasp position, band position and height of the band head used that are referred to when wearing the wristwatch. For example, the watch may determine, from the stored data, the three parameters corresponding to the bluetooth account number according to the currently connected bluetooth account number and display the three parameters to the user. The prompt box 1602 is used to prompt the user of the position of the watch buckle parameter and the watch strap parameter, so that the user can wear the watch strap according to the parameters correctly. The user snaps the clasp 204 in place and moves the wristband clip 206 into place. According to the parameters indicated in the indication frame 1602, if the wristwatch used by the user is of the structure shown in fig. 7, the user first needs to select the band head 206b with the corresponding height to be mounted on the band body 206a, then fix the flexible substrate 207 and the second watchband 202 via the connection member 211, then fasten the clasp 204 on the corresponding position to wear the wristwatch, and after the wristwatch is worn, move the band body 206a to the corresponding position, so that measurement can be started. If the wristwatch used by the user is of the structure shown in fig. 13, the user can first fasten the clasp 204 at the corresponding position to wear the wristwatch, then mount the clasp head 206b at the corresponding height on the clasp body 206a after wearing the wristwatch, move the clasp body 206a to the corresponding position, and then start the measurement after fastening the clasp 212 on the first watchband 201 to the clasp slot 213 on the second watchband 202.

After the user wears the watch according to the parameters prompted by the prompt box 1602, the processor on the watch can acquire the pressure signal measured by the pressure sensor array in real time, and determine whether the pressure meets the measurement requirement.

When the pressure signal reaches the measurement requirement (i.e. when the signal quality reaches the standard), the display interface of the watch may jump from the b diagram in fig. 16 to the c diagram in fig. 16, the prompt box 1604 and the waveform diagram 1605 of the pulse wave are displayed in the c diagram in fig. 16, after the measurement is finished, the display interface of the watch may jump from the c diagram in fig. 16 to the d diagram in fig. 16, and the prompt box 1606, the "click view waveform diagram" control 1607 and the prompt box 1608 are displayed on the d diagram in fig. 16.

Optionally, a "click view or update wear parameters" control 1609 may also be present in the interface shown in figure 16, d. For example, if the user uses the different gauge band head heights indicated by the prompt box 1602 and the gauge band head 206b during the measurement, but the gauge band 206 position and the gauge band 204 position are both worn according to the parameters indicated by the prompt box 1602, after the measurement is completed according to the flow shown in fig. 16, the user may click the control 1609, and the display interface of the wristwatch may be similar to the interface shown in fig. 15 e, and the user may update and save at least one of the three parameters on the interface.

For descriptions of other controls or prompt boxes in the interfaces shown in the c-chart and the d-chart in fig. 16, reference may be made to the descriptions of the interfaces shown in the c-chart and the d-chart in fig. 15, which are not repeated here for brevity.

Fig. 17 is a schematic diagram of a display interface on the wristwatch when the user does not use the wristwatch shown in fig. 2 for the first time, and for the description of the interfaces shown in fig. 17, reference may be made to the description of the interfaces shown in fig. 16, and for brevity, description will not be repeated here.

In the case that the pressure signal does not meet the measurement requirement (i.e. the signal quality does not reach the standard), the display interface of the watch may jump from the b diagram in fig. 17 to the c diagram in fig. 17, where the interface in fig. 17 displays a prompt box 1610 for prompting the user: please move the watchband hoop position, wait 3s after each movement, and stop moving after hearing the beeping. I.e., by prompting the user to move the meter band 206 so that the pressure sensor can pressurize the user's radial or ulnar artery. For example. After the watch has beeped, the user stops moving the watch band 206 and the watch begins to measure the pulse wave of the radial or ulnar artery contact at the user's wrist. The display interface of the wristwatch can be changed from the interface shown in fig. 17 c to the interface shown in fig. 17 d, and a prompt box 1612 and a waveform chart 1611 of the pulse wave are displayed as shown in fig. 17 d. Prompt box 1612 is used to prompt the user: the semi-fist is kept in the detection process and the arm is still, namely, the user is prompted to keep the correct posture in the measurement process, so that the accuracy of the measurement result can be improved. After the measurement is finished, the display interface of the watch can be jumped from the interface shown in d diagram in fig. 17 to the interface shown in e diagram in fig. 17, and a prompt box 1613, a click view waveform diagram control 1614, a prompt box 1615 and a click update wearing parameter control 1616 are displayed as the interface shown in e diagram in fig. 17.

For descriptions of the prompt box 1613, the "click view waveform" control 1614, and the prompt box 1615, reference may be made to the corresponding descriptions in the d-diagram in fig. 15, and for brevity, description is omitted here.

For the "click update wearing parameters" control 1616, since the user is not using the watch for pulse wave measurements for the first time, the watch has previously stored three parameters, the clasp 204 position, the band clasp 206 position, and the height of the band clasp head 206b, corresponding to the user. Because the measurement signal does not reach the standard when the three wearing parameters are used, at least one of the three parameters is inaccurate and needs to be updated. After the user clicks the "click update wearing parameters" control 1615, the display interface of the watch may jump from the interface shown in e diagram in fig. 17 to the interface shown in f diagram in fig. 17, where a prompt box 1617, prompt information 1618, and "save" control 1619 are displayed. The prompt box 1617 prompts the user to input the parameters of the new position of the clasp 204, the parameters of the new position of the band 206, and the height of the newly used band head 206b. If the user has only moved the band 206 during the process of qualifying the pressure signal, the position of the band 206 may be updated to update the parameters of the position of the band 206 to the parameters of the new position in which the band 206 is located; if the user moves the band 206 and changes the position of the clasp 204 during the process of making the pressure signal reach the standard, the parameter of the position of the band 206 can be updated to the parameter of the new position of the band 206, and the parameter of the position of the clasp 204 can be updated to the new clasp hole 205 number N of the clasp 204; if the user fails to make the pressure signal satisfactory by changing the position of the meter band 206 and the position of the meter button 204, the user may replace the meter band head 206b at another height. Optionally, if the user replaces the meter cuff 206b with another height to re-measure, the meter cuff 206b with another height may be used to re-measure according to the process shown in fig. 16 or fig. 17, and after the measurement is finished, the three parameters including the position of the clasp, the position of the watchband and the height of the meter cuff are updated and stored, so that when the user measures the pulse wave with the watch next time, the parameters are prompted to the user, thereby greatly reducing the complexity of the operation when the user measures, simplifying the operation process, and further improving the user experience.

For the case where the user wears the wristwatch shown in fig. 10 to measure pulse waves, the interface displayed by the wristwatch is similar to that shown in fig. 15 to 17, except that the position parameters of the clasp 212 may be included in addition to the clasp 204 position, band clasp 206 position, and height of the used clasp head 206b when prompting the user to output the wearing parameters or prompting the user to wear the reference parameters. Otherwise, the remaining display interfaces are similar to those shown in fig. 15 to 17, and are not repeated here for brevity.

The application provides a watch for measuring pulse waves, which comprises a watch body, a watchband with scales, a pressure sensor array and a watch band hoop, wherein the watchband is connected with the watch body and provided with scales, and the pressure sensor array is detachably arranged on the watch band. The meter band is formed by assembling a meter band body and meter band heads, and the same meter band body can be matched with the meter band heads with different heights respectively. After a user wears the watch, the watch band is sleeved on the watch band, the fastened watch band applies pressure to the watch band, the user moves the position of the watch band on the watch band, the watch band (watch band head) presses the pressure sensor array on the watch band, the pressure sensor array presses the pulse position (such as radial artery or ulnar artery) of the user, the pressure sensor array measures the pulse of the pulse position of the user, and accordingly pulse waves are obtained and displayed on a display of the watch body, in the measuring process, the user can change the applied pressure by changing the watch band position, moving the watch band position, or changing the height of the watch band head, and the like, namely, the user can actively adjust the applied pressure, and the watch is convenient to wear and measure; and the position of the meter buckle, the position of the meter band and the height of the meter band head are recorded in the measuring process of the user, so that the parameters are prompted to the user when the user measures the pulse wave by using the watch next time, the user can wear and measure according to the parameters, the complexity of the operation of the user in measuring is greatly reduced, the operation flow is simplified, and the user experience is further improved.

The embodiment of the application also provides wrist type electronic equipment for measuring pulse waves, which comprises a display and a wrist strap connected with the display, wherein an air bag is fixed on the wrist strap, a flexible substrate is fixed on the air bag, a pressure sensor array is fixed on a first area of the flexible substrate, a space (i.e. no contact) exists between the first area of the air bag and the first area of the flexible substrate, and a second area of the air bag is in contact with a second area of the flexible substrate. Wherein the second region of the bladder is made of a rigid material and the first region of the bladder is made of an elastic material (e.g., rubber, etc.). When the user measures pulse waves by using the electronic equipment, after the air bag is inflated, the first area of the air bag is contacted with the first area of the flexible substrate and extrudes the flexible substrate, so that the pressure sensor array on the flexible substrate is contacted with the pulse beating position of the user, the pressure sensor array measures the pulse of the pulse position (such as radial artery or ulnar artery) of the user, and the pulse waves are obtained and displayed on the display. The wrist pressure measuring device is simple and convenient in wearing and measuring process, flexible and comfortable in pressurizing mode, and pressure is applied to the part of the wrist of the user (namely, the first area of the air bag applies pressure to the wrist of the user), and pressure is not applied to the whole or most areas of the wrist of the user, so that the comfort of the user when the user measures pulse waves by using the wrist watch can be improved, and the user experience is improved.

The wrist wearable device for measuring pulse waves provided by the application is described below with reference to specific examples.

Fig. 18 is a schematic structural diagram of an example of a smart watch provided by the present application. The schematic structure diagram of the back surface (i.e., the surface opposite to the display screen on the watch body) of the smart watch shown in fig. 18, as shown in fig. 18, the smart watch provided in the embodiment of the present application includes a first watchband 201 and a second watchband 202, one end of the first watchband 201 is connected to the watch body 203, one end of the second watchband 202 is provided with a watch buckle 204, and the first watchband 201 is provided with a watch buckle hole 205, after the user wears the watch, the watch buckle 204 passes through the watch buckle hole 205, so that the watch is fixed on the wrist of the user.

As shown in fig. 18, an airbag 214 is provided on the back surface of the second band 202. Alternatively, the bladder 214 may be secured (e.g., by gluing, etc.) to the second wristband 202, or alternatively, the bladder 214 may be removably coupled to the second wristband 202. The flexible substrate 207 is fixed on the air bag 214, and the pressure sensor array 208 is fixed on the flexible substrate 207, for example, the pressure sensor array 208 may be adhered on the flexible substrate 207, or the connection manner between the pressure sensor array 208 and the flexible substrate 207 may be an electrical connection. Electrical leads 209 are provided on the flexible substrate 207. Optionally, an FPC connector 210 is disposed between the flexible substrate 207 and the meter body 203, and an electrical lead 209 is used for transmitting a pressure signal at the radial artery or the ulnar artery of the user detected by the pressure sensor array 208 to the FPC connector 210, where the FPC connector 210 is used for transmitting the pressure signal to the meter body 203, and after the processor in the meter body 203 processes (e.g. filters, etc.) the pressure signal, a pulse wave image may be obtained, and further, some parameter features (e.g. blood pressure, heart rate, arteriosclerosis risk index, etc.) may be extracted from the pulse wave image, so that the obtained pulse wave image and parameter features may be displayed to the user on the display of the meter body.

As shown in fig. 18, an air passage interface 215 is connected between the air bag 214 and the watch body 203, a micro air pump 216 is arranged inside the watch body 203, and the micro air pump 216 can inflate the air bag 214 through the air passage interface 215 so as to expand the air bag, or the air in the air bag 216 can be transmitted to the micro air pump through the air passage interface 215 so as to be released.

After the user wears the watch and inflates the air bag 214, the air bag 214 will expand and squeeze the flexible substrate 207, so that the pressure sensor array 208 on the flexible substrate 207 contacts with the radial artery or ulnar artery of the user, and the pressure sensor array 208 can measure and obtain the pressure signal of the radial artery or ulnar artery of the user.

It should be understood that fig. 18 is only exemplary, and should not impose any limitation on the structure of the smart watch in the embodiments of the present application.

Fig. 19 is a schematic diagram showing a side view of the air bag 214, the pressure sensor array 208, and the flexible substrate 207 on the second band in the wristwatch shown in fig. 18, and the pressure sensor array 208 is fixed on the flexible substrate 207 as shown in fig. 19.

In an embodiment of the present application, the placement location of the pressure sensor array 208 may be determined by data statistics. For example, the location area of the radial artery or ulnar artery on the second wristband 202 when the watch is worn by a plurality of users may be counted to determine the location of the pressure sensor array 208 on the flexible substrate 207. For example, in the example shown in fig. 19, the pressure sensor array 208 is disposed on a first region of the flexible substrate 207.

As shown in fig. 19, the flexible substrate 207 may be fixed to the air bag 214 by means of gluing or electrical connection, and the air bag 214 may be detachably connected to the second wristband 202 by means of a plurality of connecting members 217, wherein any one of the connecting members 217 may be detachably connected to the second wristband 202. For example, the connection member 217 may be a buckle, etc., and embodiments of the present application are not limited herein.

As shown in fig. 19, an air passage interface 215 is provided at the connection between the air bag 214 and the watch body 203, a micro air pump 216 is provided inside the watch body 203, and the micro air pump 216 can inflate the air bag 214 through the air passage interface 215 to expand the air bag 214, or can transmit air in the air bag 214 to the micro air pump 216 through the air passage interface 215 to release.

As shown in fig. 19, there is a space between the first region 207a of the flexible substrate and the airbag 214, that is, the first region 207a of the flexible substrate is not in contact with the airbag 214 in the case where the airbag 214 is not inflated, and in the embodiment of the present application, the region of the airbag 214 that is not in contact with the flexible substrate 207 may be referred to as the first region 214a of the airbag, that is, the first region 214a of the airbag and the first region 207a of the flexible substrate are not in contact in the case where the airbag 214 is not inflated, and there is a space therebetween. This prevents excessive pressure from being applied to the pressure sensor array 208 during inflation of the air bag 214, and prevents the pressure sensor array 208 from being deformed greatly to cause damage to the detection result.

In the embodiment of the present application, the region of the airbag 214 other than the first region 214a may be referred to as the second region 214b of the airbag, and the region of the flexible substrate other than the first region 207a may be referred to as the second region 207b of the flexible substrate, as shown in fig. 19, the second region 214b of the airbag and the second region of the flexible substrate 207b are in contact without inflation of the airbag 214, and there is no space therebetween.

In some embodiments, the first region 214a of the balloon may be made of an elastic material (e.g., rubber, etc.), and upon inflation of the balloon, the first region 214a of the balloon may be inflated such that the first region 214a of the balloon contacts and presses the flexible substrate with the first region 207a of the flexible substrate, such that the pressure sensor array 208 of the first region 214a on the flexible substrate contacts and applies pressure to the radial or ulnar artery of the user, thereby measuring the pressure signal. The pressure signal may be transmitted through electrical leads 209 on the flexible substrate 207 to the FPC connector 210, which FPC connector 210 is used to transmit the pressure signal into the meter body 203 so that the processor in the meter body 203 further processes the pressure signal.

While the second region 214b of the balloon is made of a rigid material, the second region 214b of the balloon does not undergo inflation deformation after inflation of the balloon 214. That is, in the embodiment of the present application, after the airbag 214 is inflated, a local area of the airbag (i.e., the first area 214a of the airbag) may generate pressure on the flexible substrate 217, and other areas of the airbag (i.e., the second area 214b of the airbag) may not generate pressure on the flexible substrate 207 in contact therewith. In other words, the embodiment of the application adopts a mode of locally pressurizing the air bag, compared with a mode of completely pressurizing the air bag, the pressure required is smaller, the pressure is applied to the local part of the wrist of the user (namely, the radial artery or the ulnar artery of the wrist of the user) and the pressure is not applied to the whole or most of the area of the wrist of the user, so that the comfort of the user when measuring the pulse wave by using the wrist watch can be improved, and the user experience is improved.

It should be understood that the distribution of the pressure sensor array 208 on the flexible substrate 207 in the embodiment of the present application should not be limited by the illustration of fig. 19. In other embodiments of the present application, the pressure sensor array 208 may be disposed at other locations on the flexible substrate 207 as desired, so long as the pressure sensor array 208 may contact the radial artery or ulnar artery at the wrist of the user during the measurement process, and embodiments of the present application are not limited herein.

Fig. 20 is a schematic diagram of a side view of the air bag on the second strap of the wristwatch shown in fig. 18, with the pressure sensor and the flexible substrate in an inflated state, and as shown in fig. 20, after the air bag 214 is inflated by the micro air pump 216 in the watch body, the first area 214a of the air bag may be made of an elastic material, so that the air bag may be inflated and deformed. While the second region 214b of the balloon is made of a rigid material and does not undergo inflation deformation. Thus, the first region 214a of the balloon will be inflated and deformed, so that the first region 214a of the balloon contacts the first region 207a of the flexible substrate and presses the flexible substrate, i.e. the first region 214a of the balloon will exert pressure on the first region 207a of the flexible substrate, the first region 207a of the flexible substrate will deform under the action of the pressure, so that the pressure sensor array 208 of the first region 207a on the flexible substrate contacts the wrist surface skin S at the radial artery or ulnar artery of the user and exerts pressure on the wrist surface skin S at the radial artery or ulnar artery, thereby measuring the pressure signal.

In the wristwatch shown in fig. 19 and 20, the configuration, size, etc. of the pressure sensor array 208 may refer to the description of the pressure sensor array in fig. 6, and for brevity, the description is omitted here.

Fig. 21 is a schematic diagram of an example of a user wearing the watch shown in fig. 19 or fig. 20 to measure pulse waves at the radial artery, and as shown in fig. 21, the user buckles the clasp 204 on the second watchband 202 into one of the clasp holes on the first watchband 201, after wearing the watch, when the user starts to measure pulse waves, the user can operate on the display on the watch, so as to control the micro air pump 216 in the watch body 203 to inflate the air bag 214 in the second watchband through the air passage interface 215. The first region 214a of the balloon will be inflated and deformed such that the first region 214a of the balloon contacts the first region 207a of the flexible substrate and presses the flexible substrate, i.e. the first region 214a of the balloon will exert pressure on the first region 207a of the flexible substrate, the first region 207a of the flexible substrate will deform under the effect of the pressure, such that the pressure sensor array 208 of the first region 208a on the flexible substrate contacts the wrist surface skin S at the radial artery of the user and applies pressure to the radial artery or ulnar artery, thereby measuring a pressure signal.

The pressure signal measured by the pressure sensor array 208 is transmitted to the FPC connector 210 through the electrical lead 209 on the flexible substrate 207, and the FPC connector 210 transmits the pressure signal to the meter body 203, so that the processor in the meter body 203 processes the pressure signal to obtain a waveform chart of pulse waves, further, some parameter characteristics (such as blood pressure, heart rate, arteriosclerosis risk index and the like) can be obtained from the pulse wave image, and thus the obtained pulse wave image and the parameter characteristics can be displayed to a user on a display of the meter body.

In the process of inflating the air bag 214 through the air passage interface 215 in the watch body 203, as a possible implementation manner, the processor on the watch can acquire the pressure signal obtained by measuring the pressure sensor array 208 in real time and determine whether the pressure meets the measurement requirement, so that in the process of inflating the air bag 214 through the air passage interface 215 in the micro air pump 216, the processor on the watch can determine whether the pressure signal obtained by measuring the pressure sensor array 208 meets the measurement requirement in real time, if the pressure signal meets the measurement requirement, the processor on the watch can control the micro air pump 216 to stop inflating the air bag 214, and the air bag 214 can maintain the corresponding pressure until the measurement is completed. The processor on the watch can also adjust the pressure of the air in the bladder 214 in real time during the measurement process based on the pressure signal measured by the pressure sensor array 208.

In the process of inflating the air bag 214 through the air passage interface 215 in the meter body, as another possible implementation manner, a pressure threshold may be set in advance, and the inflation of the air bag 214 is stopped when the air pressure in the air bag 214 reaches a preset threshold. After the air pressure in the air bag reaches the preset threshold, the processor on the watch can judge whether the pressure signal measured by the pressure sensor array 208 meets the measurement requirement, if not, the processor on the watch can adjust the pressure (pressure) of the air in the air bag 214 by controlling the micro air pump 216 to realize the adjustment of the pressure of the air bag 214 acting on the pressure sensor, so as to adjust the pressure signal measured by the pressure sensor array 208 until the pressure signal measured by the pressure sensor array 208 meets the measurement requirement.

In some embodiments, a pressure sensor may be provided inside the watch body 203 for measuring the pressure of the air in the bladder 214, in such a way that a processor in the watch may determine whether the air pressure in the bladder 214 reaches a preset threshold. Alternatively, the processor in the wristwatch may also determine whether the air pressure in the bladder 214 has reached a preset threshold based on the pressure signal measured by the pressure sensor array 208 on the band, and stop inflating the bladder 214 when the air pressure in the bladder 214 has reached the preset threshold. In the embodiment of the present application, there is no limitation to the specific implementation process of the wristwatch to determine whether the air pressure in the air bag 214 reaches the preset threshold.

A schematic flow of measuring pulse waves by a user wearing the wristwatch shown in fig. 18 to 20 will be exemplified below.

Before the user measures the pulse wave using the wristwatch, the user places the wristwatch band on the wrist, and fastens the second band 202 and the first band 201 by the clasp 204. Fig. 22 is a schematic diagram showing an example of a display interface on a wristwatch when a user measures pulse waves with the wristwatch. As shown in a diagram a in fig. 22, a "pulse wave measurement" control 2201 is displayed on the main interface of the wristwatch, and detected items are displayed in the control 2201, including, for example: heart rate, blood pressure, heart rhythm, etc. After the user clicks the "pulse wave measurement" control 2201, the processor in the watch can control the micro air pump 216 to inflate the air bag 214 through the air channel interface 215, and in the process of inflating the air bag 215, the first area 214a of the air bag will expand and deform, so that the first area 214a of the air bag contacts with the first area 207a of the flexible substrate and presses the flexible substrate, that is, the first area 214a of the air bag will generate pressure on the first area 207a of the flexible substrate, the first area 207a of the flexible substrate deforms under the action of the pressure, so that the pressure sensor array 208 of the first area 207a on the flexible substrate contacts with the wrist surface skin S at the radial artery of the user, and pressure is applied to the radial artery, so that a pressure signal is measured. The pressure signal measured by the pressure sensor array 208 is transmitted to the FPC connector 210 through the electrical leads 209 on the flexible substrate 207, the FPC connector 210 transmits the pressure signal to the meter body 203, and the processor in the meter body 203 processes the pressure signal to determine whether the pressure signal meets the measurement requirement.

If the pressure signal does not meet the measurement requirement, the processor on the watch can adjust the pressure (pressure) of the air in the air bag 214 by controlling the micro air pump 216 to realize the adjustment of the pressure of the air bag 214 acting on the pressure sensor array 208, so as to adjust the pressure signal measured by the pressure sensor array 208 until the pressure signal measured by the pressure sensor array 208 meets the measurement requirement. After the pressure signal reaches the measurement requirement, the display interface of the wristwatch can jump to the interface shown in b diagram in fig. 22, and a prompt box 2202 and a waveform diagram 2203 of the pulse wave are displayed on the interface shown in b diagram in fig. 22. Prompt box 2202 is used to prompt the user: the semi-fist is kept in the detection process and the arm is still, namely, the user is prompted to keep the correct posture in the measurement process, so that the accuracy of the measurement result can be improved. The processor in the watch body can process the pressure signals measured by the pressure sensor array 208 in real time to obtain a waveform chart of pulse waves, and the waveform chart is displayed to a user in real time in the display screen of the watch. After the measurement is finished, the display interface of the watch can be changed from the interface shown in b diagram in fig. 22 to the interface shown in c diagram in fig. 22, and a prompt box 2204, a click view waveform diagram control 2205 and a prompt box 2206 are displayed on the interface shown in c diagram in fig. 22.

The prompt box 2204 is used for prompting the user to finish detection, if the user needs to view the waveform diagram of the final pulse wave, the user can click the "click view waveform diagram" control 2205, and after clicking, the waveform diagram of the final pulse wave can be displayed to the user on the display screen of the watch. The waveform of the pulse wave is obtained by processing (e.g., differential amplifying, filtering, etc.) the pressure signal measured by the pressure sensor array 208 by a processor in the watch body. Further, the processor in the table body may analyze the pulse wave waveform chart, and may extract the results of some measurement indexes from the pulse wave waveform chart, for example, including: blood pressure values, heart rate conditions, and risk of arteriosclerosis, etc.), prompt box 2206 is used to prompt the user for the results of these measurement metrics for the user to view.

In some embodiments, after the measurement is completed, the processor in the watch may also release air in the bladder 214 by controlling the micro air pump 216.

According to the watch for measuring pulse waves, the air bag is fixed on the watchband, the flexible substrate is fixed on the air bag, the pressure sensor array is fixed on the first area of the flexible substrate, a space (namely no contact) exists between the first area of the air bag and the first area of the flexible substrate, the second area of the air bag is in contact with the second area of the flexible substrate, the second area of the air bag is made of a rigid material, and the first area of the air bag is made of an elastic material (such as rubber). When the user wears the watch to measure pulse waves, the miniature air pump of the watch inflates the air bag, the first area of the air bag is inflated, the first area of the air bag is contacted with the first area of the flexible substrate and extrudes the flexible substrate, the pressure sensor array on the flexible substrate is contacted with the pulse beating part of the user, the pressure sensor array measures the pulse of the pulse part (such as radial artery or ulnar artery) of the user, and accordingly the pulse waves are obtained and displayed on the watch. The wearing measurement process is simple and convenient, because the mode of local pressurization of the air bag is adopted, the needed pressure can be smaller, the pressure is applied to the local part of the wrist of the user (namely, the radial artery or the ulnar artery of the wrist of the user), and the pressure is not applied to the whole wrist or most of the area of the user, so that the comfort of the user when the user measures the pulse wave by using the wrist watch can be improved, and the user experience is improved.
