The application provides a pulse acquisition device 10, the pulse acquisition device 10 is used for gathering the pulse signal of user for relevant personnel to handle, study. Referring to fig. 1, in some embodiments, the pulse collecting device 10 (lower computer) communicates with the upper computer 30 through the cloud server 20, receives related control instructions of the upper computer 30, and sends feedback information (including the collected pulse signals) to the upper computer 30, so as to realize remote collection of the pulse signals. In other embodiments, the pulse collecting device 10 can also directly communicate with the host computer 30 (e.g. the pulse collecting device 10 communicates with the host computer 30 through a communication cable), without communicating with the host computer 30 via the cloud server 20, so as to achieve on-site collection of pulse signals.

In the specific embodiment of the present application, the above-mentioned upper computer 30 may be one of a personal computer, a smart mobile phone, a tablet computer, etc., and those skilled in the art should understand that these upper computers are not limited to the specific embodiments of the present application; other computer devices that may be used to communicate with the pulse acquisition apparatus 10, send related instructions to the pulse acquisition apparatus 10, and receive feedback information sent by the pulse acquisition apparatus 10, as may be applicable to the present application, are also included within the scope of the present application and are incorporated herein by reference.

The following describes in detail the specific embodiments of the pulse acquisition apparatus 10 described above.

Referring to fig. 2, the pulse acquisition apparatus 10 includes a frame 100. Wherein the stand 100 is used for providing support for other components of the pulse acquisition device 10, and the other components are directly or indirectly mounted on the stand 100 to provide stable and accurate pulse acquisition results. The pulse signal is collected by the pulse collecting component 300, and the pulse collecting component 300 is driven by the pulse collecting driving component. Specifically, the pulse acquisition driving component drives the pulse acquisition component 300 to move to the target position and cling to the relevant position of the wrist of the user. The pulse signals collected by the pulse collecting component 300 are sent to the upper computer 30 by a communication component (not shown) for relevant calculation, processing and analysis by the upper computer 30. The communication component is electrically connected with the control component of the pulse acquisition device 10, provides the control component with a remote instruction sent by the upper computer 30, and sends feedback information (including the acquired pulse signal) obtained by the control component based on the provided control instruction to the upper computer 30.

The control component of the pulse collecting device 10 is further electrically connected with the pulse collecting driving component and the pulse collecting component. After the control component receives the remote instruction, the instruction is analyzed, and the pulse acquisition driving component is controlled to act to drive the pulse acquisition component 300, so that the pulse acquisition component 300 moves to a corresponding position, and pulse signals of a user are acquired through the pulse acquisition component 300.

In some embodiments, the pulse acquisition device 10 further includes an image acquisition component 400 for performing image acquisition and transmission. For example, the image acquisition assembly 400 includes an image sensor (sometimes also referred to as a camera) and associated circuitry. The image capturing assembly 400 is mounted on the frame 100 and is electrically connected to the aforementioned control assembly (e.g., via a communication cable), so that the control assembly controls the image capturing assembly 400 to capture images of the wrist of the user according to the image capturing instructions sent by the host computer 30. The image collected by the image collection assembly 400 is sent to the upper computer 30 by the control assembly, so that the upper computer user can observe and adjust the position of the pulse collection assembly 300 in real time, and the accurate positioning of the collection position and the accurate collection of the pulse signals are realized. When the pulse collecting device 10 (lower computer) communicates with the upper computer 30 through the cloud server 20, the on-site image collected by the image collecting component 400 can be provided by a remote operator (such as a professional such as a medical staff) to provide a professional service for the user without going to the site; when the pulse collecting device 10 is directly in communication with the upper computer 30 (e.g. the pulse collecting device 10 is in communication with the upper computer 30 via a communication cable), a user (or a professional such as a medical staff) can collect the pulse signal on site via the upper computer 30, and at this time, the image collected by the image collecting assembly 400 can be used for an operator to directly observe the collecting position, angle, etc. of the pulse collecting assembly 300 on the display of the upper computer 30 (the upper computer 30 can also process the collected image to assist in judging), without repeatedly and directly observing the working state of the pulse collecting assembly 300, so that the collecting efficiency of the pulse is improved.

Of course, it should be understood by those skilled in the art that the image capturing module 400 may be directly controlled by the host computer 30 to capture images, in addition to being controlled by the control module to capture images, which may have the same or substantially the same effects as those described above. At this time, the image acquisition assembly 400 is electrically connected with the communication assembly, and the communication assembly receives the image acquisition instruction sent by the upper computer 30 and then sends the image acquisition instruction to the image acquisition assembly 400, or decodes the image acquisition instruction and then sends the image acquisition instruction to the image acquisition assembly 400; the image acquisition component 400 acquires an image upon receiving a corresponding instruction.

In order to adjust the acquisition angle of the image acquisition assembly 400 to acquire the image required by the operator, the image acquisition assembly 400 is mounted on the image acquisition adjustment device 410, and the image acquisition adjustment device 410 is fixedly disposed on the frame 100. Wherein the image acquisition assembly 400 is movable relative to the image acquisition adjustment device 410. For example, a user (or a professional such as a medical professional on site) may manually adjust the position of the image acquisition assembly 400 on the image acquisition adjustment device 410, and in some embodiments the image acquisition adjustment device 410 is provided with a chute along which the image acquisition assembly 400 may slide to adjust the viewing angle; for another example, the pulse acquisition device 10 includes a pulse acquisition drive unit (e.g., a drive motor and a screw mechanism) that drives the image acquisition assembly 400 relative to the frame 100 (and certainly relative to the wrist of the user) based on the aforementioned image acquisition control instructions to adjust the viewing angle of the image acquisition assembly 400 (e.g., the aforementioned drive motor drives the image acquisition assembly 400 via the screw mechanism).

With continued reference to fig. 2, in some embodiments, the pulse acquisition device 10 further includes an arm carrier 500 for carrying the user's arm and securing the position of the user's arm to improve positioning efficiency in acquiring pulses. The arm bearing part 500 is disposed at the bottom of the frame 100, and is used for bearing the arm of the user, and further providing support when the pulse collecting component 300 presses the arm of the user and collects the pulse signals. For example, the pulse collecting driving assembly includes a first driving unit 210, and the first driving unit 210 is used to drive the pulse collecting assembly 300 mounted thereon to move so as to press or separate from the arm of the user. Taking fig. 2 as an example, the first driving unit 210 includes three driving rods, and the first pulse collecting component 300 correspondingly includes three pulse collecting units, and the three pulse collecting units are respectively installed at the end of one driving rod; each driving rod is controlled by the control component to move independently, so that the corresponding pulse acquisition unit is driven to move. In the example shown in fig. 2, each driving lever moves in the vertical direction (first direction), and the arm bearing 500 is located at the bottom of the stand 100, so that each driving lever drives the corresponding pulse collecting unit to move toward or away from the arm bearing 500, i.e., each driving lever drives the corresponding pulse collecting unit to press or separate from the arm surface of the user. Of course, the three driving rods can be linked, and the control assembly can control the three driving rods to move at the same time, so that the cost is saved. Specifically, in order to accurately obtain the pulse signals of the user for subsequent analysis and processing, the three pulse acquisition units are a first pulse acquisition unit, a second pulse acquisition unit and a third pulse acquisition unit, and the first pulse acquisition unit, the second pulse acquisition unit and the third pulse acquisition unit are respectively used for acquiring the pulse signals of the positions of the cun, the guan and the chi of the user. Thus, the first pulse acquisition unit, the second pulse acquisition unit, and the third pulse acquisition unit are longitudinally distributed, i.e., arranged along the arm stretching direction of the user.

The driving rod can be driven by a driving mode which can be existing or can occur in future. Such as the drive rods described above, are driven by gears/racks, cylinders, hydraulic, linear motors, belts/pulleys, etc., and those skilled in the art will appreciate that these are by way of example only and are not limiting of the embodiments of the present application.

In the case where the operator cannot learn about the site in time during the remote operation or the communication quality is poor (for example, the network delay is large), the pulse acquisition assembly 300 may continue to press down under the condition that the wrist surface of the user is pressed, which causes discomfort or danger. In view of this, the pulse taking device 10 described above is optionally provided with a taking pressure sensing device connected to the control assembly and provided to the arm carrier 500 for taking the pressure of the wrist of the user against the arm carrier 500 and transmitting the detected pressure signal to the control assembly. When the pulse collecting component 300 continuously applies pressure to the arm of the user, the control component judges whether to continuously drive the pulse collecting component 300 to press down according to the pressure signal. For example, the control component programmatically determines if the pressure signal reaches a preset threshold. For another example, the control assembly is provided with a signal comparison circuit having two inputs and one output, one of the inputs being the pressure signal (first input) and the other input being the reference signal; when the pressure signal is smaller than the reference signal, the output signal is high (or low), and when the pressure signal is larger than the reference signal, the output signal is low (or high); the output end of the signal comparison circuit is connected with the control end of the first driving unit, so that the output signal of the signal comparison circuit controls the first driving unit to act or stop acting. The signal comparison circuit can be realized based on a common voltage comparison circuit. In addition, the signal comparison circuit can also be configured as a hysteresis comparison circuit so as to avoid unstable output signals caused by signal fluctuation. The pressure sensor can be implemented based on a pressure sensor, a micro switch, etc., but is not limited thereto.

In particular, in some embodiments, the above-mentioned pressure sensor is disposed opposite to the pulse acquisition component 300, so as to improve the accuracy of sensing the wrist pressure of the pulse acquisition component 300.

The arm carrier 500 of the pulse collecting device 10 optionally includes an arm positioning slot 510 and a hand rest 520, wherein the arm positioning slot 510 is used for positioning the arm of the user to further improve the positioning efficiency and accuracy in cooperation with the pulse collecting assembly 300; the hand pillow 520 is slidable relative to the arm positioning slot 510 to enhance the comfort of the user when collecting the pulse.

Particularly, when the hand rest 520 is provided, if the above-mentioned pressure sensor is also provided, the pressure sensor is optionally provided corresponding to the hand rest 520, for example, the pressure sensor is provided on the upper surface, the inside or the bottom of the hand rest 520, or is provided on the arm positioning slot 510 corresponding to the position of the hand rest 520, so as to further improve the accuracy of sensing the pressure of the pulse acquisition assembly 300 on the wrist of the user, and reduce the influence of the weight of other parts of the arm of the user.

In addition to the first drive unit, the pulse acquisition device 10 is optionally provided with a second drive unit 220, which second drive unit 220 is likewise electrically connected to the control unit. With continued reference to fig. 2, the second driving unit 220 is used to drive the first driving unit 210 to move. Specifically, the first driving unit 210 is mounted on the second driving unit 220; the second driving unit 220 drives the first driving unit 210 to move, thereby driving the pulse collecting component 300 to move. In the case that the first driving unit 210 drives the pulse collecting member 300 to move along a straight line (in a first direction), the second driving unit 220 gives the pulse collecting member 300 a component of movement in a direction perpendicular to the straight line (a second direction), i.e., the first direction is orthogonal to the second direction; thus, the first driving unit 210 and the second driving unit 220 cooperate to drive the pulse acquisition assembly 300 to perform a three-dimensional motion in space. In an exemplary embodiment, the first driving unit 210 drives the pulse collecting member 300 to move in a vertical direction; the second driving unit 220 drives the first driving unit 210 to move in the horizontal direction, thereby driving the pulse collecting assembly 300 to move in the horizontal direction.

In addition, as described above, in the case where the operator cannot know the site in time or the communication quality is poor (for example, network delay is large) or the like at the time of remote operation, the pulse acquisition assembly 300 may continue to press down with the wrist surface of the user pressed, causing discomfort or danger. For this purpose, in addition to the above-mentioned pressure sensor, the pulse collecting device may further include a buffer component, through which the pulse collecting component 300 is mounted on the above-mentioned pulse collecting driving component (for example, the above-mentioned first driving unit 210), so as to reduce the discomfort caused by the pulse collecting component 300 abutting against the wrist of the user. For example, the cushioning assembly is a cushion/mass, an air spring, or the like, made of a compression spring or resilient material (e.g., rubber, silicone, or foam material mass).

The buffer component and the collecting pressure sensing device can be alternatively arranged or simultaneously arranged. When the buffer assembly and the pressure sensor are simultaneously arranged, the buffer assembly can enable the pulse acquisition assembly 300 to be gradually conducted to the wrist of the user and the pressure sensor, so that the comfort of the user can be improved, and the phenomenon of unstable output signals caused by pressure signal fluctuation can be reduced.

In order to further reduce the risk that the continuous depression of the pulse acquisition assembly 300 may cause, the pulse acquisition device may optionally be additionally provided with a reset instruction generating device. The reset instruction generating device is electrically connected with the control component and is used for generating a reset instruction. For example, the reset instruction generating means is a contactor, a physical button, a virtual button displayed on a screen, or a scram button. The control unit controls the pulse collecting driving unit (e.g. the first driving unit 210) to drive the pulse collecting unit 300 to reset, for example, to drive the pulse collecting unit 300 to move to a limit position away from the wrist of the user based on the reset command.

Fig. 3 shows a block diagram of the electronic control system of the pulse acquisition apparatus 10 in an exemplary embodiment. The pulse acquisition device 10 includes a communication assembly including a communication module (and its peripheral circuitry) and an antenna (for communicating with an upper computer). The control assembly includes a motor motion control module and a data acquisition module, wherein the motor motion control module controls X, Y, Z axis drive motor to operate, wherein the Z axis drive motor is included in the first drive unit 210, and the X and Y axis drive motors are included in the second drive unit 220. The sensors communicated with the data acquisition module are respectively contained in the first pulse acquisition unit, the second pulse acquisition unit and the third pulse acquisition unit. The image acquisition assembly comprises a camera image module (and a peripheral circuit thereof) in the figure, and the camera image module is communicated with the communication module. Here, it should be understood by those skilled in the art that the block diagram of the electric control system shown in fig. 3 is only an example, and not any limitation to the specific embodiments of the present application.

Fig. 4 illustrates a pulse acquisition process by the pulse acquisition device 10 in an exemplary embodiment. The upper computer 30 communicates with the pulse collecting device 10 through the cloud server 20. After the pulse of the user is collected, the upper computer 30 is connected with the server and calls the pulse collecting device 10, and three-party connection is established. The pulse acquisition device 10 and the cloud server 20 perform initialization, wherein the server initializes data receiving and storing, and the pulse acquisition device 10 resets the motion axis and performs self-checking to confirm that the camera image transmission is normal and the sensor data value is normal. After the subject is in place, the arm is placed on the arm carrier 500 (e.g., arm positioning groove 510 described above) and held stationary. The remote operator observes the wrist position through the image shot by the camera and sends a control instruction to the pulse acquisition device 10 through the upper computer 30 so as to control the motor motion control module to control the pulse acquisition assembly 300 to move and contact the corresponding position of the wrist of the tested person. The pulse acquisition component 300 acquires sensor data and transmits to the host computer 30. The upper computer 30 draws a continuous, complete and effective pulse wave pattern according to the sensor data, and the pulse acquisition process is finished.

The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
