Abstract
Description
Technical Field
[0001] This invention relates to the fields of traditional Chinese medicine pulse diagnosis equipment, flexible sensing and air pressure control algorithm technology, and particularly to an intelligent pulse diagnosis pressurization device and dynamic control method based on multi-level sub-airbags. Background Technology
[0002] Traditional Chinese medicine pulse diagnosis, as an important component of traditional diagnostic methods, requires doctors to apply different depths of pressure (superficial, middle, and deep) to the cun, guan, and chi positions with their fingers to obtain pulse information. In recent years, electronic pulse diagnosis devices have gradually emerged, but current technology still has the following problems:
[0003] Pressure homogenization: The single airbag structure causes the pressure in the cun, guan, and chi zones to change synchronously, making independent control impossible;
[0004] Displacement interference: Minor movements of the arm during measurement can cause distortion in the sensor output. Traditional servo mechanisms are complex and lack reliability.
[0005] Response lag: The response speed of existing air pump / valve control systems is usually greater than 200ms, which makes it difficult to guarantee continuous and stable acquisition of pulse waves.
[0006] Some existing solutions attempt to improve the situation by using three independent airbags, mechanical servo, or wristwatch-style structures, but these solutions suffer from drawbacks such as large size, high energy consumption, and complex structure, and fail to simultaneously meet the requirements of "three-zone independent control, displacement fault tolerance, and rapid response". Summary of the Invention
[0007] In order to achieve the above-mentioned objectives and other advantages of the present invention, the first objective of the present invention is to provide an intelligent pulse diagnosis and pressurization device based on multi-level sub-airbags, including a layered airbag structure, an air pressure sensor, a pulse wave sensor, a micro pump, a micro valve, and a controller.
[0008] The hierarchical airbag structure includes a main airbag and multiple independent sub-airbags. The main airbag is supplied with base pressure by the micro-pump, and the sub-airbag array covers the inch, close, and scale areas respectively, and is independently adjusted by the micro-valve.
[0009] The pressure sensor is used to collect the real-time pressure value of each sub-airbag;
[0010] The pulse wave sensor is used to extract the real-time pulse wave amplitude and rising edge slope;
[0011] The controller is used to independently and dynamically adjust the pressure in the three zones of cun, guan, and chi based on the data collected by the air pressure sensor and the pulse wave sensor.
[0012] Furthermore, a flexible substrate is provided to connect the main airbag and the sub-airbag array.
[0013] Furthermore, a flexible sliding layer is provided between the sub-airbag and the air pressure sensor.
[0014] Furthermore, the thickness of the flexible sliding layer is 50 μm, and the coefficient of friction is <0.05.
[0015] Furthermore, the main airbag is made of medical-grade TPU film with a volume of 12–15 mL, providing a uniform reference pressure;
[0016] The basic pressure is 50–100 mmHg;
[0017] The sub-airbag is 1cm in size. 2 .
[0018] A second objective of this invention is to provide a dynamic control method for an intelligent pulse diagnosis and pressurization device based on multi-level sub-balloons, comprising the following steps:
[0019] The micro pump is controlled to inflate the main airbag to a preset base pressure;
[0020] The sub-airbags are adjusted to preset pressures according to floating, mid-floating, and sinking modes via the micro-valve.
[0021] Obtain the real-time pressure values of each sub-airbag collected by the pressure sensor;
[0022] PID control is performed based on the real-time pressure value and the set pressure to achieve closed-loop correction of the deviation between the target pressure and the actual pressure of each sub-airbag.
[0023] The real-time pulse amplitude and rise slope collected by the pulse wave sensor are obtained.
[0024] Fuzzy control is performed based on the real-time pulse amplitude and the rising edge slope to avoid static pressure stability but pulse waveform distortion.
[0025] Furthermore, the step of performing PID control based on the real-time pressure value and the set pressure to achieve closed-loop correction of the deviation between the target pressure and the actual pressure of each sub-airbag includes:
[0026] The instantaneous deviation is obtained by subtracting the actual pressure from the set pressure.
[0027] The proportional term, integral term, and derivative term are calculated based on the instantaneous deviation to obtain the total control quantity;
[0028] The micropump is controlled to determine whether to inflate or deflate based on the sign of the total control quantity.
[0029] When the absolute value of the instantaneous deviation is less than the threshold and continues for a preset time, it is determined to be a static steady state.
[0030] Furthermore, the step of performing fuzzy control based on the real-time pulse amplitude and the rising edge slope to avoid static pressure stability but pulse waveform distortion includes:
[0031] Calculate the moving average of the pulse amplitude over a preset time period;
[0032] Extracting the frequency domain energy distribution;
[0033] If the real-time pulse amplitude is less than 0.8 times the moving average and the rising edge slope decreases, then the pressure of the sub-inflator is increased by 5 mmHg.
[0034] If the real-time pulse amplitude is greater than 1.2 times the moving average and the frequency domain energy shifts, then the pressure of the sub-airbag is reduced by 5 mmHg.
[0035] If the pulse distortion is greater than 10%, adjust the main airbag pressure by ±3 mmHg.
[0036] If the frequency domain energy concentration decreases, increase the pressure of the airbag at the joint by 3 mmHg;
[0037] If the three signals are not synchronized, the pressure at the closing point should be adjusted first as the reference.
[0038] When the pulse signal-to-noise ratio is ≥20dB and the amplitude fluctuation is <5%, it is determined to enter a stable acquisition state.
[0039] A third objective of the present invention is to provide a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the above-described method.
[0040] A fourth objective of the present invention is to provide a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of the above-described method.

[0091] Total control quantity: ΔP = P + I + D.
[0092] The micropump is controlled to determine whether to inflate or deflate based on the sign of the total control quantity ΔP.
[0093] When the absolute value of the instantaneous deviation is less than the threshold and lasts for a preset time, for example, when |e| < 1 mmHg and lasts for 200 ms, it is determined to be a static steady state.
[0094] S500: Obtain the real-time pulse amplitude and rising edge slope collected by the pulse wave sensor;
[0095] In this embodiment, the pulse wave sensor samples at 500Hz to extract the real-time pulse wave amplitude A(t) and the rising edge slope dA / dt.
[0096] S600. Fuzzy control is performed based on the real-time pulse amplitude and the rising edge slope to avoid static pressure stability but pulse waveform distortion.
[0097] Dynamic compensation (fuzzy control based on pulse wave characteristics) is used to address situations where static pressure is stable but the pulse waveform is distorted.
[0098] Furthermore, the step of performing fuzzy control based on the real-time pulse amplitude and the rising edge slope to avoid static pressure stability but pulse waveform distortion includes:
[0099] Calculate the moving average of the pulse amplitude over a preset time period; for example, calculate the 5-second moving average of the pulse amplitude.
[0100] Extract the frequency domain energy distribution (the proportion of the main peak energy in the range of 0.5–10 Hz);
[0101] If the real-time pulse amplitude A is less than 0.8 times the moving average Furthermore, if the slope dA / dt of the rising edge decreases, the pressure of the control sub-airbag increases by 5 mmHg;
[0102] If the real-time pulse amplitude A > 1.2 times the moving average Furthermore, the frequency domain energy shift controls the pressure of the sub-airbag to decrease by 5 mmHg;
[0103] If the pulse distortion is greater than 10%, adjust the main airbag pressure by ±3 mmHg.
[0104] If the frequency domain energy concentration decreases, increase the pressure of the airbag at the joint by 3 mmHg;
[0105] If the three signals are not synchronized, the pressure at the closing point should be adjusted first as the reference.
[0106] In this embodiment, the microvalve response time is controlled to be <20ms; each adjustment amount is ≤±5mmHg to avoid sudden waveform changes.
[0107] When the pulse signal-to-noise ratio is ≥20dB and the amplitude fluctuation is <5%, it is determined to enter a stable acquisition state.
