Referring to fig. 1, the present application provides an acquisition device 10 for acquiring blood pressure and pulse information. The acquisition device 10 mainly comprises two pulse acquisition components: the first acquisition assembly 100 and the second acquisition assembly 200 are respectively used for acquiring pulse signals of the left hand and the right hand of a user, and the first acquisition assembly 100 and the second acquisition assembly 200 are respectively used for acquiring pulse signals of the left hand and the right hand of the user. The acquisition device in some embodiments further comprises a host 500, the first acquisition assembly 100 and the second acquisition assembly 200 being mounted on the host 500, respectively; wherein the electronic device of the acquisition device 10 is arranged in the host 500.

The first acquisition assembly 100 includes a first grip portion 110 and a first support portion 120, while the second acquisition assembly 200 includes a second grip portion 210 and a second support portion 220. The first holding part 110 is used for holding by a left hand of a user, so that the angle of the left hand of the user is fixed; the second holding part is used for holding the user by the right hand, so that the angle of the right hand of the user is fixed. The first supporting portion 120 and the second supporting portion 220 are respectively used for supporting the left arm and the right arm of the user, so that the burden of the user is reduced, the left hand angle of the user is further fixed in an auxiliary manner, and the position accuracy of the sensing device on the wrist of the user when the user collects pulse signals by self-service is improved.

The first grip portion 110 is provided with a first electrode, which in some embodiments is a conductive metal sheet coated on the surface of the first grip portion 110; accordingly, the second holding portion 210 is provided with a second electrode, which in some embodiments is a conductive metal sheet coated on the surface of the second holding portion 210.

The sensing device of the acquisition device 10 needs to be covered on a relevant portion of the wrist (such as a radial artery position of the wrist) of the user to acquire the pulse signal. Taking the first collecting assembly 100 as an example, the first collecting assembly 100 includes a first driving device 130 and a first sensor assembly 140, where the first driving device 130 is used to drive the first sensor assembly 140 to move towards a direction of pressing the radial surface of the wrist of the left hand of the user, so that the first sensor assembly 140 collects the radial artery pulse signal of the wrist of the left hand of the user. For example, in some embodiments, the first sensor assembly 140 is free or at a distance from the user's wrist when not being driven to compress the user's wrist so that the user places the arm in place. The first drive 130 can be realized in various ways, for example on the basis of an eccentric, a screw, a linkage or an airbag. Similar to the first acquisition assembly 100, the second acquisition assembly 200 includes a second driving device and a second sensor assembly, where the second driving device is configured to drive the second sensor assembly to move in a direction of pressing against a radial surface of the wrist of the right hand of the user, so as to acquire radial artery pulse signals of the wrist of the right hand of the user between the second sensor assemblies.

In addition, the acquisition device 10 also includes an information processing component for processing related information, such as communicating with the first sensor component and the second sensor component and acquiring corresponding sensed information, storing and processing data, communicating with other devices, and the like. The information processing unit is connected to the first electrode (disposed on the first grip 110) and the second electrode (disposed on the second grip 210) via wires, respectively, so as to collect bioelectric signals of the left hand of the user via the first electrode and collect bioelectric signals of the right hand of the user via the second electrode. For example, referring to fig. 6, a first electrode at a left hand position is connected to a non-inverting input terminal of a comparator in a signal acquisition circuit of an information processing component, a second electrode at a right hand position is connected to an inverting input terminal of the comparator, and the human body and the comparator are grounded at the same time, so that an I lead for acquiring electrocardiographic data is formed, and the information processing component acquires an output signal of the comparator and acquires electrocardiographic data of a user after processing.

In some embodiments, the first driving device and the second driving device are implemented based on an air bag, so that a comfortable use experience is provided for a user, and positioning accuracy is improved by increasing a contact surface. Referring to fig. 2, the first acquisition component is still illustrated. The primary collection assembly 100 includes a primary bladder 130 and a primary sensor assembly 140, wherein the primary bladder 130, when inflated, drives the primary sensor assembly 140 to move in a direction to compress the user's left hand radial surface, e.g., the primary sensor assembly 140 is mounted directly on the surface of the primary bladder 130 on the side near the user's wrist, or the primary sensor assembly 140 is mounted on another component, and this component may be driven by the primary bladder 130 and drive the primary sensor assembly 140 to move together. Similarly, the secondary collection assembly 200 includes a secondary bladder and a secondary sensor assembly, wherein inflation of the secondary bladder drives the secondary sensor assembly in a direction to compress the user's right hand radial surface. At this time, the collecting device 10 further includes an air pump electrically connected to the aforementioned information processing assembly, and the information processing assembly controls the air pump to operate, for example, controls the air pump to inflate the first air bag 130 and the second air bag. In some embodiments, the air pump is mounted within the host 500.

In some embodiments, the first collection assembly 100 further includes a first air bag barrel 150, through which the left hand arm of the user passes for positioning of the arm of the user, and accommodates the first air bag 130, the first sensor assembly 140, etc., such as the first air bag 130 being fixedly mounted in the first air bag barrel 150. Based on the aforementioned securement of the first bladder cartridge 150 to the user's arm, the positioning of the first sensor assembly 140 on the user's wrist surface will be more accurate. In some embodiments, the first balloon 130 is annular and is used to wrap the left wrist of the user, so that better positioning can be provided without generating larger local pressure to cause discomfort of the user, and the acquisition success rate of the pulse signals of the user is improved. Similarly, the second acquisition assembly 200 further includes a second balloon barrel 250 for the user's right hand arm to pass therethrough for arm positioning by the user, and houses the second balloon, second sensor assembly, etc. described above, and in some embodiments the second balloon is annular and is used to wrap around the user's right wrist.

In some embodiments, to ensure comfort and in some cases safety of the user, the collecting device 10 further includes an air bag releasing assembly 400 electrically connected to the information processing assembly, and when the air bag releasing assembly 400 is triggered, the information processing assembly controls the air pump to release the first air bag 130 and the second air bag, for example, the information processing assembly controls the air pump to stop inflating the first air bag and the second air bag, or the information processing assembly controls the air pump to deflate the first air bag and the second air bag, or the information processing assembly controls the air pump to enter a pumping state, so as to reduce the pressure exerted on the wrist of the user by the first sensor assembly and the second sensor assembly as soon as possible, thereby avoiding safety accidents. Wherein the above-described airbag release assembly optionally includes a first release unit 410 and/or a second release unit 420. The first release unit 410 (if any) is disposed on the first grip portion 110, for example, the first release unit 410 is implemented based on a touch switch, a micro switch, or a push switch, and is triggered when the user presses/touches or is triggered when the user stops pressing/touching; the second release unit 420 (if any) is disposed on the second grip portion 210, for example, the second release unit 420 is implemented based on a touch switch, a micro switch, or a push switch, and is triggered when the user presses/touches or is triggered when the user stops pressing/touching.

It will be appreciated by those skilled in the art that the implementation of the first and second release units 410 and 420 is only exemplary and not intended to limit the embodiments of the present application; any implementation of the first and second release units 410, 420 that may be present in the present application or later is applicable to the present application, is within the scope of the present application and is incorporated herein by reference.

Wherein, to ensure the safety of the user, the airbag release assembly 400 includes the first release unit 410 and the second release unit 420 in some embodiments, and when either the first release unit 410 or the second release unit 420 is triggered, the airbag release assembly 400 is considered to be released, wherein the first release unit 410 and the second release unit 420 are configured to be triggered when the user stops pressing/touching. Therefore, only when the user simultaneously grips the first grip portion 110 and the second grip portion 210 (or simultaneously presses the push switches on the left and right sides), the air pump inflates the first air bag and the second air bag, otherwise, when the user releases either side grip portion (or releases either side push switch), the inflation action of the air pump is stopped, and the first air bag and the second air bag are released, thereby protecting the personal safety of the user. In one embodiment, the first release unit 410 and the second release unit 420 (for example, the first release unit 410 and the second release unit 420 are both touch or press switches) are connected in series to an input end of the information processing component, and are respectively configured to:

-conducting when touched or pressed by a user and considered to be in an unactuated state;

off when the user stops touching or pressing and is considered to be in a triggered state.

Of course, the above-described embodiments are merely examples, and are not intended to limit the application in any way; other embodiments, whether presently existing or later to be developed, are suitable for use with the present application and are intended to be encompassed within the scope of the application as described herein. For example, the output signals of the first release unit 410 and the second release unit 420 are respectively input signals of an and circuit, and the output signals of the and circuit are input signals of an information processing component.

In some embodiments, the sensor assembly on each side includes a plurality of sensor units to increase the acquisition success rate of pulse information. Taking the first sensor assembly 140 as an example, referring to fig. 3, the first sensor assembly 140 includes a plurality (e.g., 3) of first sensor units 141, and the sensor assembly 140 moves in the arrow direction in fig. 3 when driven to cover the surface of the user's wrist (in a state as in fig. 4); these first sensor units 141 are circumferentially distributed at the left wrist position of the user and are arranged towards the wrist surface of the user, so that a larger coverage is provided on the wrist surface of the user, and it is ensured that the radial pulse signal of the user can be captured and collected by the at least one sensor unit 141, so as to ensure a higher pulse signal collection efficiency. The second sensor assembly, like this, comprises a number (e.g. 3) of second sensor units; these second sensor units are circumferentially distributed at the right wrist position of the user and are arranged towards the wrist surface of the user.

Of course, the pulse signal acquisition efficiency can be ensured in other ways. For example, in some embodiments, the first sensor assembly and the second sensor assembly are movably mounted, in particular the first sensor assembly and the second sensor assembly are circumferentially movable relative to the respective wrists of the user, so as to adjust the relative positions of the sensor assemblies and the wrists of the user. At this time, the first sensor assembly and the second sensor assembly are respectively provided with a sensor unit, so that the cost is saved.

Optionally, in the case that the first sensor assembly and the second sensor assembly are movably mounted, the first sensor assembly and the second sensor assembly may also respectively include a plurality of sensor units as described above, so as to reduce the movement amount of the sensor assemblies during the adjustment process and ensure the acquisition efficiency of the pulse signals to the greatest extent.

The sensor unit in each embodiment of the application is used for detecting the pressure change generated when the artery beats and converting the pressure change into an electric signal which can be more intuitively observed and detected. A common pulse sensor unit belongs to a micro-pressure sensor, and the output mode can comprise analog output and digital output, and the pressure process of pulse beating is converted into an electric signal through micro-pressure materials (such as a piezoelectric sheet, a bridge and the like) and is output.

The first holding portion 110 and the second holding portion 210 are vertically disposed in some embodiments, so that the user can hold the first holding portion 110 and the second holding portion 210 with their two hands opposite to each other, which is convenient for accurate positioning of the wrist collection portion of the user.

In some embodiments, the acquisition device 10 further includes an input component (e.g., keyboard, microphone, etc.) and an output component (e.g., speaker, display screen, etc.), each in communication with the information processing component; optionally, the information processing component, the input component and the output component are all installed in the host 500, so that the user can input related information and obtain an output analysis result.

In some embodiments, the first acquisition assembly 100 and the second acquisition assembly 200 are not fixedly mounted on the host computer 500, but may be swingably (or rotatably) mounted on the host computer 500, thereby providing a comfortable operating experience for users of different heights. For example, referring to fig. 5, the first collecting assembly 100 and the second collecting assembly 200 are respectively installed on the host 500 through a rotating shaft or a link mechanism, and the first collecting assembly 100 and the second collecting assembly 200 can swing left and right in a horizontal plane relative to the host 500, so that a user can find the most comfortable arm bending angle, interference in collecting pulse information is reduced, and accuracy of the pulse information is improved.

The above details specific embodiments of the acquisition device comprising the first acquisition assembly 100, the second acquisition assembly 200. Of course, in some embodiments, only one side of the acquisition component is provided, and pulse information acquisition can also be realized. According to another aspect of the present application, there is also provided an acquisition apparatus including a third acquisition component and an information processing component. The third acquisition component is used for acquiring pulse information of a user and comprises a third holding part, a third supporting part, a third driving device and a third sensor component; the third holding part is used for holding by a user, the third supporting part is used for supporting the arm of the user, and the third driving device drives the third sensor assembly to move towards the direction of pressing the radial surface of the user during working. The information processing component communicates with the third acquisition component. In the case where no contradiction occurs, the respective components (e.g., the third collecting assembly, the third holding portion, the third supporting portion, the third driving device, the third sensor assembly, the information processing assembly) in the collecting device respectively operate in the same or substantially the same manner as the respective components (e.g., the first collecting assembly, the first holding portion, the first supporting portion, the first driving device, the first sensor assembly, the information processing assembly) in the above embodiments, which are not described herein in detail and are incorporated herein by reference.

According to another aspect of the present application, there is also provided a method for acquiring blood pressure and electrocardiographic information, the method being implemented based on the acquisition device described above, the method being performed in some embodiments by an information processing component in the acquisition device described above. Referring to fig. 7, the above-described method includes step S710, step S720, step S730, and step S740.

Wherein, in step S710, the information processing assembly controls the first sensor assembly to move in a direction of pressing the left-hand radial surface of the user, and controls the second sensor assembly to move in a direction of pressing the right-hand radial surface of the user. Simultaneously, the information processing assembly monitors the sensing data of the first sensor assembly and the second sensor assembly in real time. In step S720, when a first pulse signal is detected by the first sensor assembly (e.g., the first sensor assembly starts detecting pulse fluctuations) or a second pulse signal is detected by the second sensor assembly (e.g., the first sensor assembly starts detecting pulse fluctuations), the information processing assembly acquires a first blood pressure value by at least one of the first sensor assembly and the second sensor assembly, e.g., records a current pressure average of the sensor assembly that first detected pulse fluctuations as the first blood pressure value or records pressure averages of both sensor assemblies as the first blood pressure value. Referring to fig. 8, taking the first sensor assembly 140 as an example, the first sensor assembly 140 includes one or several (e.g., 3) first sensor units 141, and the first sensor units 141 are pressed against the surface of the arm 610 (shown as a cross-section) of the user to sense the real-time pressure of the blood in the radial artery 620.

Subsequently in step S730, an information processing component monitors the first pulse signal by the first sensor component and the second pulse signal by the second sensor component during the compression of the first sensor component and the second sensor component; in step S740, when the first pulse signal or the second pulse signal satisfies a threshold condition (for example, as the pressure of the sensor assembly gradually increases, the amplitude of the corresponding pulse signal gradually decreases to be smaller than a preset amplitude threshold, in other words, the blood vessel wall is subjected to the blood and the pressure of the sensor assembly are approximately equal, it is determined that the threshold condition is satisfied, referring to fig. 9), the information processing assembly acquires a second blood pressure value through the first sensor assembly or the second sensor assembly.

In step S750, the information processing component takes the first blood pressure value as a diastolic pressure and the second blood pressure value as a systolic pressure.

In some embodiments, where the left and right sides may differ in operation and the operation is not synchronized (e.g., a single-sided jam), independent pressurization of the sides may be provided to achieve functional redundancy, thereby reducing or avoiding mechanical failure affecting the acquisition process. In the step S710, the information processing component sends a first acquisition instruction to the first acquisition component and sends a second acquisition instruction to the second acquisition component; the first driving device drives the first sensor assembly to move towards the direction of pressing the left-hand radial surface of the user based on the first acquisition instruction, and the second driving device drives the second sensor assembly to move towards the direction of pressing the right-hand radial surface of the user based on the second acquisition instruction.

For the process of acquiring electrocardiograph data, the acquisition device comprises a first electrode and a second electrode which are respectively arranged on the left and right holding parts. Accordingly, in some embodiments, the above method further comprises step S760 (not shown). Specifically, in this step S760, the information processing component acquires electrocardiographic information of the user through the first electrode and the second electrode; the first electrode is arranged on a first holding part of the first acquisition component, and the second electrode is arranged on a second holding part of the second acquisition component. For example, with continued reference to fig. 6, the output of the comparator circuit is based on the electrocardiographic information collected by the first and second electrodes, which is amplified as electrocardiographic data of the user. Fig. 10 shows the variation of the amplitude of the electrocardiographic waveform (increasing and decreasing) as the left and right side sensor assemblies increase and decrease the wrist pressure of the user.

For illustrative purposes, fig. 11 shows several cases where the electrocardiographic waveforms differ in amplitude in the case where the sensor assembly pressure applies different pressures. Wherein, curve A represents that the corresponding sensor assembly has not detected any pulse, and the waveform is a straight line; curve B represents the signal waveform of the corresponding sensor assembly when it just begins to detect a pulse, for example, when the pulse signal sensed by the sensor assembly just reaches the resolution of the sensor assembly, so that the output of the sensor assembly begins to change; curve C represents the signal waveform detected during an increase in pressure applied by the sensor assembly to the user's wrist; curve D represents the signal waveform with the greatest amplitude that can be detected during an increase in pressure applied by the sensor assembly to the user's wrist. The electrocardiographic waveform starts from curve a, changes from curve B and curve C to curve D, and changes from curve D to curve C and curve B to curve a as the pressure applied by the sensor assembly increases gradually. At this time, the pressure sensed by the corresponding sensor unit when the electrocardiographic waveform first becomes the curve B is taken as the first blood pressure value, and the pressure sensed by the corresponding sensor unit when the electrocardiographic waveform second becomes the curve B is taken as the second blood pressure value. Therefore, the blood pressure value corresponding to the pressure of the current sensor assembly on the wrist of the user can be conveniently determined based on the change of the waveform amplitude recorded by the acquisition device.

In some embodiments, in order to prevent inaccurate measurement or measurement failure caused by misoperation of a user, the user is required to simultaneously grasp two sides of the gripping part to start acquisition work. Accordingly, in the above step S710, the information processing component detects the lead states of the first electrode and the second electrode; if the first electrode and the second electrode form a lead, the first sensor assembly is controlled to move towards the direction of pressing the radial surface of the left hand of the user, and the second sensor assembly is controlled to move towards the direction of pressing the radial surface of the right hand of the user. In some embodiments, the user may release the grip portion on one side or both sides during the measurement due to discomfort or misoperation, and the method further includes step S770 (not shown) to prevent the system from being damaged by the user (e.g., the sensor assembly is excessively pressurized to cause discomfort to the user) or inaccurate/failed measurement. In this step S770, the information processing unit interrupts the blood pressure acquisition if the leads of the first electrode and the second electrode are disconnected. Further, to ensure user safety, the pressure applied by the sensor assembly to the user's wrist is also optionally reduced rapidly. Specifically, the apparatus further includes an air pump for driving the first sensor assembly and the second sensor assembly to move by supplying air to the air bag; in step S770, if the leads of the first electrode and the second electrode are disconnected, the information processing unit interrupts blood pressure collection and controls the air pump to pump air from the air bladder, thereby rapidly reducing the pressure applied by the sensor unit on the wrist of the user.

Optionally, the sensor assemblies on the left side and the right side are respectively provided with a plurality of sensor units to form a sensor array, so that the success rate of collecting effective pulse signals by the sensor assemblies is improved, and a user does not need to adjust the wrist angle to adapt to the sensor assemblies. Taking the first sensor assembly 140 as an example, the first sensor assembly 140 includes one or several (e.g., 3) first sensor units 141, and the first sensor assembly 140 moves in the arrow direction in fig. 3 when driven to cover the user wrist surface (state as in fig. 4); these first sensor units 141 are circumferentially distributed at the left wrist position of the user and are arranged towards the wrist surface of the user, so that a larger coverage is provided on the wrist surface of the user, and it is ensured that the radial pulse signal of the user can be captured and collected by the at least one sensor unit 141, so as to ensure a higher pulse signal collection efficiency. The second sensor assembly, like this, comprises a number (e.g. 3) of second sensor units; these second sensor units are circumferentially distributed at the right wrist position of the user and are arranged towards the wrist surface of the user. By analyzing whether the pressure information detected by the 3 sensor units on each side is regular, it can be determined whether the obtained sensing information of the corresponding sensor unit is ideal (the more regular the pressure information is, the more ideal the corresponding sensing information is). In the above step S730, the information processing component determines at least one first sensor unit as a first target sensor unit and determines at least one second sensor unit as a second target sensor unit according to the sensing information of the plurality of first sensor units and the plurality of second sensor units during the pressing process of the first sensor component and the second sensor component (for example, the first sensor unit with the most regular waveform is taken as the first target sensor unit and the second sensor unit with the most regular waveform is taken as the second target sensor unit); subsequently, an information processing unit monitors the first pulse signal by the first target sensor unit and monitors the second pulse signal by the second target sensor unit.
