[0023] refer to Figure 1 , 2, an embodiment of the utility model is:

[0024] A radial artery Cun, Guan and Chi acupoint data acquisition device comprises an air pump module 1, an inflatable wristband module 2, a sensing unit and a signal processing module 3, wherein the air pump module 1 is connected to the wristband module 2 via an air supply pipe 4, the signal processing module 3 is mounted on the outer surface of the wristband module 2, the sensing unit comprises a boss 5 mounted on the inner surface of the wristband module 2, the boss 5 is provided with a slide rail, three sliders 6 are slidably provided on the slide rail, a piezoelectric ceramic sheet is provided on the slider 6, and the piezoelectric ceramic sheet is connected to the signal processing module 3.

[0025] Specifically, the air supply pipe 4 is selected to be a latex air pipe to reduce the vibration influence of the air pump module 1. The flexibility of the flexible material and the longer air pipe length can achieve a vibration-absorbing effect. Finally, even if vibration still exists, it will not affect the collection of pulse data.

[0026] This application adopts modular design, and mainly consists of four electronic components to complete the overall data collection, conversion and transmission. An independent air pump module is used to inflate the wristband module to make the three piezoelectric ceramic sheets under pressure. The signal processing module receives the data of the piezoelectric ceramic sheets, thereby realizing the four parts of floating, middle pressing and sinking. The piezoelectric ceramic sheets are installed with a slider, and the position can be adjusted according to the acupoint deviation of different people. It is highly practical.

[0027] In this embodiment, the signal processing module 3 includes a sensor expansion board, a wireless transmission module, and a sensor. The sensor is connected to the piezoelectric ceramic sheet, and the sensor expansion board is connected to the wireless transmission module and the sensor.

[0028] The sensor is connected to the piezoelectric ceramic sheet through a cable inserted into the wristband module, and the piezoelectric effect is used to obtain the electrical signals of the inch, guan and chi parts; the sensor expansion board uses the Arduino sensor expansion board, which has three basic functions: one is to adapt the electrical signal obtained by the sensor to the interface and convert the signal; the second is to encode and connect the wireless module in the Arduino IDE, which is specifically the Bluetooth module in this embodiment; the third is to control the circuit of the air pump module to achieve the change of air pressure.

[0029] The Bluetooth module uses the Bluetooth wireless communication protocol to make the converted digital signal meet the Bluetooth wireless communication protocol specifications, and transmit the data wirelessly to the mobile device, realizing intelligence and convenience.

[0030] The Bluetooth module and the sensor part are fixed side by side just above the Arduino sensor expansion board, the sensor is connected to the corresponding serial port of the Arduino sensor expansion board, and the Bluetooth module is connected to the serial port of the Arduino sensor expansion board. When the user is in use, the data processing module is on the back of the hand, and the piezoelectric ceramic piece controls the electric signal of the micro air pump in the air pump module 1 under different operating conditions (i.e., realizing floating and sinking) according to the pre-programmed instructions in the Arduino sensor expansion board to the sensor part. The Arduino sensor expansion board receives the signal, converts the electric signal into a digital signal and transmits it to the Bluetooth module above. The Bluetooth module processes the digital signal into a signal that meets the Bluetooth wireless communication protocol, and transmits the data that meets the protocol to the APP of the mobile device in a wireless manner.

[0031] The wristband module 2 comprises a cloth outer shell, in which an inflatable inner bag adapted to the piezoelectric ceramic sheet is arranged, the inflatable inner bag is connected to the latex air tube, and a Velcro fastener is arranged on the cloth outer shell.

[0032] The inflatable inner bag is made of polymer material to receive the gas brought by the air pump module. In the specific implementation, it is made into a rectangular structure, and the sensing unit is located in the middle of the rectangle to prevent the slider from being deflected sideways.

[0033] The air pump module 1 is provided with a power supply device, and the power supply device is connected to the signal processing module 3 via a wire 7 .

[0034] The air pump module 1 includes a micro air pump, the micro air pump is wrapped with PU sponge, a metal hose is provided on the air outlet of the micro air pump, and the metal hose is connected to the latex air tube.

[0035] The wrapped PU sponge material reduces the basic vibration of the motor. The air pump uses a small-diameter metal hose on the air outlet, which uses its elasticity to compensate for the amplitude of the equipment vibration. It relies on the vibration consumption of the body to reduce the vibration of the air pump module and reduce the noise absorption.

[0036] The operating principles of each component are as follows:

[0037] 1. Adjust the positions of the three sliders to make them fall on the three acupuncture points of Cun, Guan, and Chi. Turn on the power switch, and the Arduino sensor expansion board controls the micro air pump to start inflating the wristband at a uniform speed. At this time, the PU sponge on the micro air pump and the small-diameter metal hose on the air outlet greatly reduce the vibration effect caused by the crankshaft of the driving air pump. After the long latex air tube slows down the vibration, the vibration generated by the micro air pump has no effect on the piezoelectric ceramic piece to obtain the pulse data.

[0038] 2. Under the air supply of the micro air pump, the air pressure of the wristband gradually increases and expands. The wristband will apply a vertical pressure to the piezoelectric ceramic piece. Under the influence of this pressure, the piezoelectric ceramic piece applies another force to the three acupoints of Cun, Guan and Chi respectively. The electrical signal obtained in the process of the piezoelectric ceramic piece gradually pressing down is fed back to the sensor. The sensor transmits the signal to the Arduino sensor expansion board and then transmits the processed signal to the Bluetooth module. According to the Bluetooth protocol, the compressed digital signal is transmitted to the mobile APP. There is an electronic pulse spectrum database in the APP. The user operates on the graphical interface to obtain the required information. The data obtained each time with large differences in data comparison will be stored separately in the database, and displayed on the graphical interface of the APP after being defined by the background experts. With the continuous growth of the beneficiary group, the electronic pulse spectrum is gradually becoming clearer and more accurate.

[0039] 3. There are four pressure intervals on the Arduino sensor expansion board. When the obtained average pressure reaches the first pressure interval, the air pump stops supplying air. After waiting for a few seconds, it continues to supply air until the average pressure reaches the second pressure interval. And so on. When it reaches the last pressure interval, the air pump maintains uniform air supply. After a few seconds, it passes through four pressure intervals again in the above method until the end. In this way, the four parts of the floating and sinking are obtained.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
