The center of the diaphragm support 234 is matched with the elastic cavity 2311 of the bionic diaphragm 231, and if the pulse taking pressure sensor 233 is provided, the pulse taking pressure sensor 233 coincides with the corresponding elastic cavity 2311. In order to simulate the pressure applied by the midwife on the points of the cunguan ruler during the pulse taking of the traditional Chinese medicine, the pressure applied by the simulated skin 21 is detected in real time by three pulse taking pressure sensors 233 which are limited in the diaphragm bracket 234 along the direction of the points.
Further, since the concave structure disposed at the center of the diaphragm support 234 may cause the elastic cavity 2311 to concave and fluctuate down along the middle of the diaphragm support 234, resulting in a decrease in simulation effect, a floating diaphragm 232 is further disposed between the bionic diaphragm 231 and the diaphragm support 234, and when the elastic cavity 2311 is downward, the floating diaphragm 232 disperses its acting force, thereby avoiding the problem of uneven stress, and finally effectively feeding back the pulsation generated by the elastic cavity 2311 to the bionic skin 21.
Pulse-taking instrument user terminal
Fig. 13 shows a user side of a pulse diagnosis apparatus with which the medical care end of the present invention is matched, after the pulse condition collecting component 8 is abutted against the pulse position of the cun-guan ruler of a patient, the medical care end remotely transmits the action direction signal to the collecting finger of the pulse condition adjusting collecting component 8 by pressing the bionic skin along the XYZ three directions, and the collecting finger is interposed in a mode of coarse adjustment and fine adjustment of rotation in sequence until the pulse condition signal of the cun-guan ruler is obtained. The communication module of the intelligent mobile terminal, such as a WIFI module and a 5G/4G module, exchanges data between the user terminal and the medical care terminal, and when the medical care terminal acquires pulse condition signals from the user terminal, the medical care terminal transmits 'fluctuation' to the simulated heart pump A through the signal amplifier, current change is converted into liquid flow fluctuation through the driving coil framework, and finally the bionic pacing component 23 is transmitted to the finger belly of a doctor.
