[0002] With the development of technology, people can detect their pulse in real time through portable pulse diagnosis equipment, and obtain the waveform of the pulse over a period of time, that is, the pulse wave, on the display interface of the pulse diagnosis equipment. The formation of the pulse wave is closely related to the heart's ejection function.

[0003] Current pulse diagnosis devices mainly use photoelectric detection methods to obtain pulses. Pulse diagnosis devices emit light beams to the surface of the skin where superficial arteries are located (such as the radial artery under the skin of the wrist) to determine the periodic changes caused by blood flow in the artery, thereby determining the pulse.

[0004] Since existing pulse diagnosis equipment is only required to collect pulse waves, it is difficult for existing pulse diagnosis equipment to obtain complete pulse waves, and part of the pulse wave is lost.

[0017] The controller collects the pulse at the first pressure value through a pulse sensor to obtain the pulse wave of the user.

[0018] In a possible implementation, the process of acquiring the first pressure value is:

[0021] When the pulse wave undergoes a change cycle, the controller controls the micro air pump to stop inflating the micro airbag, and controls the micro air release valve to release air from the micro airbag;

[0022] In the one change cycle, the peak value of the pulse wave first increases gradually from zero to reach a maximum peak value, and then gradually decreases to zero.

[0023] In a possible implementation, the method further includes:

[0024] The controller determines a second pressure value and a third pressure value according to the first pressure value, the second pressure value is less than the first pressure value, and the third pressure value is greater than the first pressure value;

[0025] The controller collects the pulse at the second pressure value and the pulse at the third pressure value respectively through the pulse sensor to obtain the pulse wave of the user at the second pressure value and the pulse wave of the user at the third pressure value.

[0043] The following describes the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. The terms used in the implementation method section of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0044] The embodiments of the present application are described below in conjunction with the accompanying drawings. Those skilled in the art will appreciate that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0045] The terms "first", "second" etc. in the specification of the application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable in appropriate circumstances, and this is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0046] Current pulse diagnosis devices mainly use photoelectric detection methods to obtain pulses. Pulse diagnosis devices emit light beams to the surface of the skin where superficial arteries are located (such as the radial artery under the skin of the wrist) to determine the periodic changes caused by blood flow in the artery, thereby determining the pulse.

[0047] The oscillometric method, also known as the pressure oscillation method, is commonly used to measure blood pressure. The process of measuring blood pressure is as follows: wrap a cuff around the user's elbow, inflate the cuff to block arterial blood flow, and then gradually deflate the cuff. During the deflation process, the gas pressure in the cuff is detected and the weak pulse wave is extracted. Figure 1 As shown in the figure, the pressure gradually increases with the inflation of the cuff, and a weak pulse wave begins to appear. When the pressure is much higher than the systolic pressure point P1, the pulse wave disappears completely. During the deflation of the cuff, the pulse wave begins to appear. When the pressure is lower than the systolic pressure point P1, the amplitude of the pulse wave suddenly increases, and when the pressure drops to the average pressure point P2, the amplitude of the pulse wave reaches the maximum. As the pressure continues to drop, the amplitude of the pulse wave gradually decreases. When the pressure is lower than the diastolic pressure point P3, the amplitude of the pulse wave continues to decrease until the pulse wave disappears.

[0048] Since the existing pulse diagnosis equipment only requires the acquisition of pulse waves, but according to the oscillometric blood pressure measurement principle, the pulse wave has a change cycle, and the current photoelectric detection method determines the pulse wave by sensing the blood, but it can only obtain a part of the pulse wave in the pulse wave change cycle, and cannot obtain the complete pulse wave change cycle. Therefore, there is a lack of pulse wave data, and the pulse wave data availability is low in the user's subsequent heart-related data analysis.

[0049] In order to solve the above problems, the embodiment of the present application provides a wearable detection device. The wearable detection device of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0050] Reference Figure 2 , Figure 2 A structural diagram of a wearable detection device provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, a wearable detection device provided in an embodiment of the present application may include a controller 1, a micro air pump 2, a micro deflation valve 3, a micro air bag 4, a pulse sensor 5 and a wristband 6;

[0051] The micro air pump 2, the micro air release valve 3 and the pulse sensor 5 are all electrically connected to the controller 1;

[0052] The pulse sensor 5 and the micro-airbag 4 are both arranged on the inner surface of the wristband 6. The pulse sensor 5 is wrapped in the micro-airbag 4, and the inner surface is the surface of the wristband 6 that contacts the user's skin;

[0053] The micro air pump 2 is connected to the micro air bag 4 , and the micro air release valve 3 is arranged on the connection passage between the micro air pump 2 and the micro air bag 4 .

[0054] The controller may be a main control circuit board, which is used to control various components of the wearable detection device and collect information sent by the components.

[0055] The micro air pump is a small-sized gas delivery device with a gaseous working medium. It is highly portable, has low noise, low power consumption, and is easy to operate. When the micro air pump is pumping air, the valve of the connecting device is opened by the atmospheric pressure, and the gas enters the cylinder; when the micro air pump is inflating, the valve is closed by the air pressure in the cylinder, and the gas enters the micro airbag.

[0056] A micro-air release valve is a small valve used to control gas flow or pressure release. It can open automatically when the internal pressure exceeds a set value, or it can be opened by a controller. In this embodiment, the micro-air release valve is an electromagnetic air release valve, which generates magnetic force by energizing the electromagnetic coil to drive the valve to open and release gas. Of course, the micro-air release valve can also be a mechanical air release valve, in which the mechanical structure deforms to push the valve to open and release gas. When there are multiple micro-air bags, the micro-air release valve can be set in the total output pipeline of the micro-air pump, or multiple micro-air release valves can be respectively set in branch pipelines connected to the micro-air bags.

[0057] The micro airbag is a tiny, gas- or liquid-filled closed structure, usually made of flexible materials, such as polyester fiber, nylon cloth, silica gel, etc. In this embodiment, Figure 2As shown, a plurality of micro airbags may be provided on the inner surface of the wristband, and the arrangement direction of the plurality of micro airbags on the inner surface is perpendicular to the extension direction of the wristband. Of course, in addition to the micro airbags, this embodiment may also use a motor or other device to achieve pressing. The controller continuously inflates the micro airbags through a micro air pump, so that the pressing pressure of the micro airbags on the user's skin increases or the downward pressing distance increases.

[0058] The pulse sensor is a sensor used to detect pulse-related signals. It can detect the pressure changes generated when the artery pulsates and convert this change into an electrical signal. The pulse sensor can be set inside the micro-balloon, and the sensor probe is attached to the inner surface of the micro-balloon to detect the arterial pulsation. Of course, the pulse sensor can also be set outside the micro-balloon, and the probe is attached to the outer surface of the micro-balloon. When the micro-balloon is inflated, the probe is located between the micro-balloon and the user's skin, directly contacting the skin to detect the arterial pulsation.

[0059] The wristband can be a fixing device for fixing the above components of the wearable detection device on the user's wrist or other superficial arteries. The material of the wristband can be silicone, rubber, or nylon, which can better adapt to the micro-airbag.

[0060] The embodiment of the present application provides a wearable detection device, which controls a micro-inflation pump and a micro-deflation valve through a controller, and the micro-inflation pump is connected to a micro-airbag, and the micro-deflation valve is arranged on the connection path between the micro-inflation pump and the micro-airbag to realize the inflation and deflation process of the micro-airbag. The device detects the pulse by applying pressure to the superficial artery. When the micro-airbag is in an inflated state, it applies pressure to the skin, and the controller can collect the pulse through the sensor wrapped in the airbag. Since the pulse wave can reach a maximum peak under the influence of appropriate pressure, the device can apply appropriate pressure to the user's skin by inflating the micro-airbag, so that the controller can obtain the change of the pulse wave from no to the maximum peak, thereby obtaining the complete waveform of the pulse wave within the change period, reducing the situation where part of the pulse wave is missing, and effectively improving the data availability of the pulse wave.

[0061] In a possible implementation, the wearable detection device further includes a pressure sensor, which is disposed on the inner surface of the wristband and is wrapped in a micro-airbag.

[0062] Among them, the pulse sensor can be used to detect arterial pulsation, and the pressure sensor can be used to detect the internal pressure of the micro-airbag or the pressure applied by the micro-airbag to the user's skin, and determine the pressing pressure of the micro-airbag on the user's skin at this time. When the pressure sensor is set inside the micro-airbag, the probe of the pressure sensor can be attached to the inner surface of the micro-airbag, and the pressure data obtained by the pressure sensor is the internal pressure value of the micro-airbag, and the internal pressure value is not necessarily the same as the pressure applied by the micro-airbag to the user's skin. Therefore, the internal pressure value obtained by the pressure sensor can be processed to determine the pressure applied by the micro-airbag to the user's skin. When the pressure sensor is set outside the micro-airbag, the probe can be set on the outer surface of the micro-airbag, so that when the micro-airbag is inflated, the probe is located between the micro-airbag and the user's skin, and the pressure applied by the micro-airbag to the user's skin at this time is directly obtained. Of course, this embodiment can also integrate the two functions of detecting pulse and detecting pressure into one sensor.

[0063] A wearable detection device provided in an embodiment of the present application is introduced above, and a method for using the wearable detection device is introduced below.

[0064] See also Figure 3 , Figure 3 A flow chart of a pulse wave detection method provided in an embodiment of the present application. Figure 3 As shown, the pulse wave detection method comprises:

[0065] S10, the controller controls the micro air pump to inflate the micro airbag according to the first pressure value, so that the pressure applied by the micro airbag on the surface of the user's wrist reaches the first pressure value;

[0066] The first pressure value is: the pressure value corresponding to the maximum peak value in the pulse wave collected during the process of continuously applying pressure to the wrist surface of the user in advance;

[0067] S11. The controller collects the pulse at a first pressure value through a pulse sensor to obtain the pulse wave of the user.

[0068] Among them, when the oscillometric method tests blood pressure, the arteries are quickly blocked by rapidly increasing the pressure. As the pressure gradually decreases, the arteries gradually return to normal from the blocked state, and the pulse wave will appear and change from weak to obvious. When the cuff pressure drops from above the systolic pressure to below the systolic pressure, the pulse wave will suddenly increase and reach its maximum value at the mean pressure. Then, as the cuff pressure drops below the mean pressure and continues to drop to the diastolic pressure or below the diastolic pressure, the pulse wave will gradually decay.

[0069] From the above content, it can be concluded that the oscillometric method mainly collects pulse waves during the process of pressure reduction. Therefore, for the pressure increase stage, which is a process of rapid pressure increase, the pulse wave changes too quickly. According to the above content, it can be inferred that if the pressure increase stage is a process of slow pressure increase, the pulse wave changes during the pressure increase process correspond to the pulse wave changes during the pressure reduction process. Figure 4 The schematic diagram of the change of pulse wave during the slow pressure increase process shown in the figure shows that when the artery is slowly pressurized, the pulse wave will also appear. When the pressure gradually reaches the diastolic pressure point p1, the pulse wave begins to increase and reaches the maximum value when the pressure exceeds the diastolic pressure point p1 and reaches the mean pressure point p2. When the pressure exceeds the mean pressure point p2 and gradually reaches the systolic pressure point p3, the pulse wave begins to attenuate. When the pressure far exceeds the systolic pressure point p3, the pulse wave disappears and the artery is in a blocked state.

[0070] Therefore, the first pressure value may be a pressure value corresponding to the mean pressure, which is the average value of blood pressure in a specific time period (such as 24 hours, a week or longer), and represents the average driving force of the heart on the blood in the circulatory system during a cardiac cycle. The controller may determine whether the pressure applied by the micro-airbag to the user's skin reaches the first pressure value through the pressure sensor. Of course, the controller may also directly control the micro-air pump to fill the micro-airbag with a fixed volume of gas corresponding to the first pressure value according to experimental data.

[0071] Specifically, the process of obtaining the first pressure value can be described as follows:

[0072] The controller controls the micro air pump to continuously inflate the micro airbag, so that the pressure exerted by the micro airbag on the surface of the user's wrist gradually increases;

[0073] During the continuous inflation of the micro-airbag, the controller continuously collects the pulse through the pulse sensor, and the pressure value corresponding to the maximum peak value in the collected pulse wave is determined as the first pressure value;

[0074] When the pulse wave undergoes a change cycle, the controller controls the micro-inflating pump to stop inflating the micro-airbag, and controls the micro-deflation valve to deflate the micro-airbag;

[0075] Among them, in one change cycle, the peak value of the pulse wave gradually increases from zero, reaches a maximum peak value, and then gradually decreases to zero.

[0076] Among them, this embodiment can not only determine the first pressure value during the boosting process, but also determine the first pressure value during the pressure relief process after the boosting process, so as to verify whether the first pressure value determined in the boosting process is reasonable, or directly take the average of the first pressure value determined in the boosting process and the first pressure value determined in the pressure relief process as the final first pressure value.

[0077] In addition to collecting the pulse wave under the average pressure, the pulse wave under the systolic pressure and the pulse wave under the diastolic pressure can also be collected as auxiliary data of the pulse wave under the average pressure. In this embodiment, the controller can determine the second pressure value (the pressure value corresponding to the diastolic pressure) and the third pressure value (the pressure value corresponding to the systolic pressure) according to the first pressure value, the second pressure value is less than the first pressure value, and the third pressure value is greater than the first pressure value, and the pulse under the second pressure value and the pulse under the third pressure value are collected by the pulse sensor respectively to obtain the user's pulse wave under the second pressure value and the user's pulse wave under the third pressure value.

[0078] The second pressure value, the first pressure value and the third pressure value can respectively correspond to light pressure (floating pulse), medium pressure (central pulse) and heavy pressure (sunken pulse) in traditional Chinese medicine pulse diagnosis. Compared with only giving the language expression of light pressure, medium pressure and heavy pressure, this embodiment can provide a unified standard pressure evaluation for traditional Chinese medicine pulse diagnosis or medical personnel, which can assist in traditional Chinese medicine diagnosis and teaching, or perform subsequent analysis such as arteriosclerosis and continuous blood pressure based on the pulse wave obtained by this method.

[0079] Since there is no fixed rule for the pulse wave values ​​corresponding to the systolic pressure and the diastolic pressure, it is difficult to determine the pressure value corresponding to the systolic pressure and the pressure value corresponding to the diastolic pressure based on the pulse wave. After determining the first pressure value corresponding to the mean pressure (the pressure value corresponding to the maximum peak value of the pulse wave), the embodiment can determine the pressure value corresponding to the systolic pressure and the pressure value corresponding to the diastolic pressure by calculating based on the mean pressure. The specific process can be described as follows:

[0080] The controller obtains the maximum peak value of the pulse wave corresponding to the first coefficient, the second coefficient and the first pressure value respectively;

[0081] The controller uses the product of the first coefficient and the maximum peak value as the first amplitude value of the pulse wave, and determines the pressure value corresponding to the first amplitude value as the second pressure value;

[0082] The controller uses the product of the second coefficient and the maximum peak value as the second amplitude value of the pulse wave, and determines the pressure value corresponding to the second amplitude value as the third pressure value.

[0083] The first coefficient and the second coefficient can be determined by a large number of clinical verifications. The value range of the first parameter and the second parameter can be: [0.5, 0.7]. The specific value can be 0.617 or 0.712. This embodiment is based on the maximum peak value when determining the first pressure value (such as Figure 4 The maximum peak value of the pulse wave corresponding to the point p2 shown in the figure is also an amplitude value of the pulse wave. By multiplying the maximum peak value with the first coefficient and the second coefficient respectively, the first amplitude value on the left side of the maximum peak value of the pulse wave can be obtained (such as Figure 4The amplitude value of the pulse wave corresponding to point p1 shown) and the second amplitude value on the right side of the maximum peak (such as Figure 4 After obtaining the first amplitude value and the second amplitude value, the pressure value corresponding to the first amplitude value can be determined as the second pressure value (such as Figure 4 The pressure value at point p1 shown in FIG. 1 is determined as the pressure value at point p1 shown in FIG. 1 ), and the pressure value corresponding to the second amplitude value is determined as the third pressure value (such as Figure 4 After determining the first pressure value, the second pressure value and the third pressure value, the controller controls the micro-pump to press the micro-airbag so that the pressing pressure of the micro-airbag on the user's skin reaches the first pressure value, the second pressure value and the third pressure value respectively, and respectively maintains the first pressure value, the second pressure value and the third pressure value for a period of time (for example, one minute) to collect the pulse wave at the first pressure value, the pulse wave at the second pressure value and the pulse wave at the third pressure value for subsequent heart data analysis.

[0084] The embodiment of the present application provides a pulse wave detection method, in which a controller controls a micro air pump to inflate a micro airbag so that the micro airbag applies a first pressure value to the user's wrist, and the first pressure value is the pressure value corresponding to the maximum peak value in the pulse wave during the process of continuously applying pressure to the user's wrist surface in advance. Therefore, when the micro airbag is continuously inflated and the pressure applied to the user's wrist surface gradually increases to the first pressure value, the pulse sensor can obtain the complete change process within the pulse wave change cycle, thereby obtaining the complete amplitude information of the pulse wave, reducing the situation of partial information loss, and effectively improving the data availability of the pulse wave.

[0085] The present application also provides an electronic device in an embodiment. Figure 5 As shown, it shows a schematic diagram of the structure of an electronic device suitable for implementing the embodiment of the present application. The electronic device in the embodiment of the present application may include but is not limited to fixed terminals such as mobile phones, laptops, PDAs (personal digital assistants), PADs (tablet computers), desktop computers, etc. Figure 5 The electronic device shown is merely an example and should not bring any limitation to the functions and scope of use of the embodiments of the present application.

[0086] like Figure 5As shown, the electronic device may include a processing device (e.g., a central processing unit, a graphics processing unit, etc.) 501, which can perform various appropriate actions and processes according to a program stored in a read-only memory (ROM) 502 or a program loaded from a storage device 508 to a random access memory (RAM) 503. When the electronic device is powered on, various programs and data required for the operation of the electronic device are also stored in the RAM 503. The processing device 501, the ROM 502, and the RAM 503 are connected to each other via a bus 504. An input / output (I / O) interface 505 is also connected to the bus 504.

[0087] Typically, the following devices may be connected to the I / O interface 505: an input device 506 including, for example, a touch screen, a touch pad, a keyboard, a mouse, a camera, a microphone, an accelerometer, a gyroscope, etc.; an output device 507 including, for example, a liquid crystal display (LCD), a speaker, a vibrator, etc.; a storage device 508 including, for example, a memory card, a hard disk, etc.; and a communication device 509. The communication device 509 may allow the electronic device to communicate with other devices wirelessly or by wire to exchange data. Although Figure 5 An electronic device having various devices is shown, but it should be understood that it is not required to implement or possess all the devices shown. More or fewer devices may be implemented or possessed instead.

[0088] An embodiment of the present application also provides a computer program product including computer-readable instructions. When the computer-readable instructions are executed on an electronic device, the electronic device implements any pulse wave detection method provided in the embodiment of the present application.

[0089] A computer-readable storage medium is also provided in an embodiment of the present application. The storage medium carries one or more computer programs. When the one or more computer programs are executed by an electronic device, the electronic device can implement any pulse wave detection method provided in the embodiment of the present application.

[0090] Through the description of the above implementation mode, the technicians in the field can clearly understand that the present application can be implemented by means of software plus necessary general hardware, and of course, it can also be implemented by special hardware including special integrated circuits, special CPUs, special memories, special components, etc. In general, all functions completed by computer programs can be easily implemented by corresponding hardware, and the specific hardware structure used to implement the same function can also be various, such as analog circuits, digital circuits or special circuits.
