[0001] This application relates to the technical field of pulse sensors. Specifically, it relates to a method, medium, device, and product for pulse acquisition. Background Art

[0002] A pulse sensor refers to a sensor used to detect pulse-related signals. Pulse sensors have two output methods: analog output and digital output. According to the signal acquisition method, they can be mainly divided into three types: piezoelectric, piezoresistive, and optoelectronic. Traditional pulse sensors mostly perform single-point pressure detection, with a fixed pressure threshold set, enabling pulse detection at different pressures. It can be seen that traditional pulse sensors cannot be adaptively adjusted according to pulse intensity and cannot obtain accurate pulse information at different stages.

[0003] Therefore, how to provide a technical solution for the adjustment method of a pulse sensor that can be adaptively adjusted has become an urgent technical problem to be solved. Summary of the Invention

[0016] Some embodiments of the present application can obtain the pulse signals in the deep-taking stage by adaptively adjusting the pressing force, ensuring the comprehensiveness and integrity of the pulse signal acquisition.

[0017] In some embodiments, the method further includes: during the process of the bionic tactile pulse sensor collecting the pulse of the target object, if the range of the pulse wave amplitude exceeds the range threshold, triggering the deep palpation stage; when the pressing force increases according to the pressure increase rule, after confirming that the pulse wave amplitude has decreased by a preset percentage, stopping the increase and generating an overpressure alarm.

Description of the Drawings

[0023] In order to more clearly illustrate the technical solutions of some embodiments of the present application, the following will briefly introduce the drawings required to be used in some embodiments of the present application. It should be understood that the following drawings only show some embodiments of the present application, and therefore should not be regarded as limiting the scope. For those of ordinary skill in the art, without creative efforts, other related drawings can also be obtained based on these drawings.

[0028] Next, the technical solutions in some embodiments of the present application will be described in conjunction with the accompanying drawings in some embodiments of the present application.

[0029] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0030] In the related art, traditional pulse sensors mostly perform single-point pressure detection and cannot simulate the dynamic process of the three-finger touch pressure of traditional Chinese medicine, resulting in the loss of pulse information. Moreover, the pressure control of traditional pulse sensors is rigid, mainly relying on fixed pressure thresholds and unable to adaptively adjust according to the pulse intensity, affecting the accuracy of floating, middle, and deep pulse taking. The pulse sensor lacks real-time feedback on the correlation of "pulse position depth - pressure change - hemodynamics" and has a large difference from the feel of traditional Chinese medicine practitioners.

[0031] In view of this, some embodiments of the present application provide a bionic touch-pressure pulse sensor. This pulse sensor can perform adaptive adjustment of the pressing force during the process of collecting pulses according to the following method for pulse acquisition. By simulating the mechanical characteristics of the three-finger touch pressure of traditional Chinese medicine practitioners and combining real-time feedback to adjust the pressure, it can accurately capture the pulse signals in the floating-taking stage, middle-taking stage, and deep-taking stage, and has high practicability.

[0032] Next, in conjunction with the attached Figure 1 Exemplarily elaborate the overall composition structure of the bionic touch-pressure pulse sensor provided for some embodiments of the present application.

[0033] As Figure 1 shown, some embodiments of the present application provide a bionic touch-pressure pulse sensor, which includes: three groups of independent touch-pressure units (corresponding to three fingers, that is, three-finger touch-pressure units), that is Figure 1The first touch pressure unit 110, the second touch pressure unit 120, and the third touch pressure unit 130 in it. Each touch pressure unit integrates a flexible pressure sensing layer 111 (or called a flexible pressure sensing array) and a driving layer 113 (as can be seen from the figure, the driving layer 113 is located in the cylindrical part of each touch pressure unit). Among them, the flexible pressure sensing layer 111 includes: a PDMS substrate and a graphene piezoresistive array (10×10 grid, resolution 0.1 mm2). The driving layer 113 includes: a micro linear motor (stroke 0 - 15 mm, thrust 0 - 10 N), which controls the touch pressure depth through a screw drive mechanism. The three touch pressure units are arranged in a "one" shape, and the spacing is adjustable (to adapt to the cun-guan-chi pulse-taking positions of different users). The surface of the pulse sensor is covered with a bionic silicone skin 112 (Shore hardness 20A) to simulate the human touch. The "pulse deficiency and excess" touch is simulated by a vibration motor to assist the doctor in operation. In addition, a microprocessor can be arranged inside the bionic touch pressure pulse sensor, or the bionic touch pressure pulse sensor is connected to a processor to facilitate the adaptive adjustment of the pressing force.

[0034] The following combines the attached Figure 2 Exemplarily illustrate the implementation process of the adaptive adjustment of the pulse sensor executed by a processor connected inside or outside the bionic touch pressure pulse sensor provided by some embodiments of the present application.

[0035] Please refer to the attached Figure 2 , Figure 2 FIG. is a flowchart of a method for pulse collection provided by some embodiments of the present application. The method for pulse collection may include: S210, during the process of the bionic touch pressure pulse sensor collecting the pulse of the target object, obtain the change rate of the pulse wave amplitude collected by the bionic touch pressure pulse sensor. S220, when it is confirmed that the change rate of the pulse wave amplitude is less than the change rate threshold, based on a preset pressure index, adjust the pressing force of the bionic touch pressure pulse sensor to obtain the pulse signals of the target object at different stages, where the stages include: the floating-taking stage, the middle-taking stage, and the deep-taking stage; and the pressing forces at different stages are different.

[0036] For example, in some embodiments of the present application, during the process of the bionic touch pressure pulse sensor collecting the pulse of the target object, the processor can obtain the change situation of the pulse wave amplitude fed back by the pulse sensor in real time. By comparing the change rate of the pulse wave amplitude calculated in real time with the change rate threshold, based on a preset pressure index, adaptively adjust the pressing force of the bionic touch pressure pulse sensor to obtain the pulse signals with different pressing forces (or called pressures) at different stages. The change rate threshold can be set flexibly. For example, the change rate threshold is 5%.

[0037] The above process is exemplarily illustrated below.

[0038] In some embodiments of the present application, before performing S210, the method for pulse condition acquisition further includes: controlling the three-finger unit of the bionic touch pulse sensor to be at the cun-guan-chi artery positions on the wrist of the target object, so as to facilitate the acquisition of the pulse condition of the target object.

[0039] For example, in some embodiments of the present application, the three-finger unit first contacts the skin of the target object with an initial pressure of 0.5N, and then calibrates it to the cun-guan-chi pulse-taking positions. Among them, the cun-guan-chi pulse-taking positions can be pre-calibrated by a doctor or automatically calibrated. For example, the target object is prompted to stretch out the wrist with the palm facing up flat. The doctor palpates the styloid process of the radius (the bony protrusion on the outer side of the wrist crease) with the index finger, and the vertical line on its inner side is the reference line for the location of the guan pulse. Specifically, the three fingers maintain a natural arch shape and adopt the "bridging method": the middle finger first determines the guan position, and the index finger and ring finger naturally drop to form a horizontal line; a disinfected cotton swab is used to draw a reference line along the longitudinal axis of the radius to ensure that the central points of the pulp of the three fingers are collinear. Alternatively, the three-finger unit can locate the bony protrusion on the outer side of the wrist crease at the wrist, and then locate to the vertical line on its inner side to achieve the automatic positioning of the cun-guan-chi pulse-taking positions.

[0040] In some embodiments of the present application, before performing S210, the method for pulse condition acquisition further includes: using the bionic touch pulse sensor to obtain the initial pulse wave amplitude of the target object within a set time period; solving the mean value of the initial pulse wave amplitude to obtain the initial pulse amplitude value of the target object.

[0041] For example, in some embodiments of the present application, when the target object is in a resting state, the pulse wave signal (as a specific example of the initial pulse wave amplitude) is continuously collected for 30 seconds (as a specific example of the set time period), and the average value of the initial pulse wave amplitude is taken as A t0 (as a specific example of the initial pulse amplitude value).

[0042] In some embodiments of the present application, S210 may include: when the increased value of the pressing force reaches the preset value, obtaining the current pulse wave amplitude of the target object in real time; determining the change rate of the pulse wave amplitude based on the initial pulse amplitude value and the current pulse wave amplitude.

[0043] For example, in some embodiments of the present application, after the acquisition of the initial pulse wave amplitude is completed, the three-finger unit is controlled to apply pressure at a preset rate (such as 0.2N / s), and the pressure (i.e., the pressing force) linearly increases from 0.5N to 2N (as a specific example of the preset value), and the pulse wave signal is collected in real time. The pulse wave signal at this time is the data in the floating-taking stage. The current pulse wave amplitude is determined through the pulse wave signal collected in real time. By calculating the current pulse wave amplitude and the initial pulse amplitude value, the change rate G of the pulse wave amplitude per unit time is obtained. PWAAmong them, the calculation formula of is as follows:

[0044]

[0045] Among them, A t is the current pulse wave amplitude at the current moment, and Δt is the time interval between the current moment and the initial moment.

[0046] For example, assume that during the pressure regulation process, the initial PWA value A t0 is 10 mV. After 10 seconds (i.e., Δt = 10), the PWA value A t increases to 12 mV. Then G PWA is calculated according to the above formula as 12% / min.

[0047] In some embodiments of the present application, S220 may include: using a control algorithm to control the pressing force to be maintained within a preset pressure range within a preset time period, and obtaining the pulse signal in the middle-taking stage; wherein, the preset pressure range is the preset pressure index.

[0048] For example, in some embodiments of the present application, when G PWA <5%, the PID control algorithm is triggered. Based on the current actual pulse wave amplitude (i.e., actual PWA), the pressure can be adaptively adjusted so that the pressure can be maintained within the optimal range (as a specific example of the preset pressure range). Control the pressing force to maintain a constant pressure within a preset time period (for example, 10 - 30 seconds). For example, the pressure is between 0.3 - 0.6 MPa (as a specific example of the preset pressure index) to accurately capture the pulse signal in this middle-taking stage. The preset time period is usually consistent with the detection period of the pulse.

[0049] Among them, the PID control algorithm is a commonly used feedback control method for adjusting the output of the system to reach the set target value. Its calculation formula is as follows:

[0050]

[0051] In the formula, P(t) is the currently applied pressing force; e(t) = PWA target -PWA actual , that is, the deviation between the target PWA and the actual PWA, reflecting the gap between the current state of the system and the desired state. K P is the proportional coefficient. For example, it is 0.8, which determines the response speed and amplitude of the system to the current deviation. K i is the integral coefficient, which is used to eliminate the historical error of the system and ensure that the system reaches a stable state in a long time. K d is the differential coefficient, which is used to predict the future behavior of the system and reduce the oscillation and overshoot of the system.

[0052] For example, assume that the target PWA value is 15 mV and the current actual PWA value is 12 mV. Then the deviation e(t) is 3 mV. According to the PID control formula, assuming that the integral term and the derivative term are both 0, calculate the currently applied pressure P(t) = 2.4 N. Through this PID control algorithm, the adaptive adjustment of the pressing force can be achieved to accurately capture the pulse signal in the middle extraction stage.

[0053] In some embodiments of the present application, S220 may include: adjusting the pressing force to a preset pressure value, and acquiring the pulse signal in the first stage of the deep extraction stage within a preset period, where the preset pressure value is the preset pressure index; during the process of reducing the preset pressure value according to a preset rule, acquiring the pulse signal in the second stage of the deep extraction stage.

[0054] For example, in some embodiments of the present application, if the PWA growth rate is < 5% within 10 consecutive seconds and the pressure fluctuation is within ±2% (indicating that the range stability meets the standard), then enter the deep extraction stage. After that, turn off the PID dynamic adjustment and switch to the constant pressure holding mode. For example, maintain the current pressure of 0.45 MPa (as a specific example of the preset pressure value) for 30 seconds (as a specific example of the preset period) to complete the deep acquisition of the pulse signal. At this time, the first stage of the deep extraction stage is completed. After 30 seconds, enter the second stage and start the linear pressure reduction program. For example, 0.45 MPa → 0.1 MPa, at a rate of 0.05 MPa / second (as a specific example of the preset rule), to avoid sudden pressure relief causing discomfort to the patient and complete the acquisition of the pulse signal.

[0055] In some embodiments of the present application, the method for collecting pulse conditions further includes: during the process of collecting the pulse conditions of the target object by the bionic touch pressure pulse sensor, if the range of the pulse wave amplitude exceeds the range threshold, trigger the deep extraction stage; when the pressing force increases according to the pressure growth rule, after confirming that the pulse wave amplitude has decreased by a preset percentage, stop increasing and generate an overpressure alarm.

[0056] For example, in some embodiments of the present application, it is also necessary to detect the sensor range to prevent overvoltage. For example, during the middle extraction stage, when the wave amplitude saturation occurs, that is, PWA ≥ 80% of the sensor range, the sinking extraction stage is triggered. After that, the pressure increases linearly at a rate of 1 N / second (as a specific example of the pressure growth rule) until the real-time wave amplitude value drops 10% from the saturation point (i.e., 80% range), that is, drops to 72% of the range, triggering an overvoltage alarm and stopping pressurization. For example, if the range of a certain pressure sensor is 0 - 100 N, when the PWA reaches 80 N (80% range), the system continues to pressurize until the wave amplitude drops to 72 N (i.e., 80 N × 90%), triggering an overvoltage alarm, implementing overvoltage protection and stopping pressurization. If the PWA drops suddenly by > 10% during the sinking extraction stage (possibly due to sensor detachment or patient movement), the process is immediately terminated and an alarm is given.

[0057] In the above embodiments of the present application, the PWA growth rate is used to reflect the response rate of blood vessels to pressure changes. The PID control algorithm adjusts the applied pressure to ensure that the PWA reaches a predetermined target value. The optimal pressure refers to the optimal force applied to the user's body surface to achieve stable control of the PWA. The combination of these two technologies can achieve precise capture of pulse signals at different stages.

[0058] The following exemplarily elaborates on the implementation process of the adaptive adjustment of the pulse sensor at different stages provided by some embodiments of the present application to completely collect the pulse signals of the target object.

[0059] The following exemplarily elaborates on the above process.

[0060] The first step is to control the three-finger unit of the bionic touch-pressure pulse sensor to be at the cun-guan-chi artery positions on the wrist of the target object.

[0061] The second step is to continuously collect the pulse wave signals for 30 seconds in the resting state, take the average value of the amplitudes, and obtain the initial pulse wave amplitude.

[0062] The third step is to apply pressure at a preset rate during the floating extraction stage and collect the pulse wave signals in real time. Calculate the PWA growth rate (i.e., G PWA ) between the real-time pulse wave amplitude and the initial pulse wave amplitude.

[0063] Through this step, the pulse wave signals (abbreviated as pulse signals) of the target object in the floating extraction stage can be obtained.

[0064] The fourth step is to enter the middle extraction stage when it is determined that the PWA growth rate is less than the change rate threshold, trigger the PID control algorithm, maintain a constant pressure within 30 seconds, and collect the pulse wave signals of the target object at this stage.

[0065] Step 5: If the PWA growth rate is <5% for 10 consecutive seconds and the pressure fluctuation is within ±2%, the sinking stage is entered.

[0066] The sixth step is to turn off the PID dynamic adjustment and switch to the constant pressure holding mode (maintain the current pressure of 0.45MPa) for 30 seconds to complete the depth collection of the pulse signal; after 30 seconds, start the linear decompression program to reduce the pressure from 0.45MPa to 0.1MPa at a rate of 0.05MPa / second, and collect the pulse wave signal at this stage.

[0067] Through the above steps, the pulse wave signals of the target object in the floating stage, the middle stage and the sinking stage can be collected.
