When the back of the hand is placed at the photoelectric switch 32, the air pump and the reversing valve are controlled to get a point, the reversing valve is reversed, the air path is unblocked, and then the airbag is inflated to fix the arm. Then the third servo motor 29 is controlled to run. Driven by the screw nut mechanism, the movable hand rest 30 can drive the arm to move. When the base 24 moves to the proximity switch 28 at one end, that is, when the arm moves to the specified position, the third servo motor 29 stops running. After the arm moves into place, the wrist should be within the field of view of the camera 19. The pulse sensor 14 is controlled to descend to 5-10mm away from the wrist to wait for the next operation. The descending height of the pulse sensor 14 can be controlled by the program, and its descending height is a fixed height. The camera 19 is controlled to take a picture and send it to the controller.

The downward pressure is preferably 5N. The safe downward pressure can be controlled to be 6N through program settings. When the pressure sensor detects that the downward pressure reaches 6N, the piston rod of the third servo electric push rod 8 is controlled to extend, thereby lifting the pulse sensor 14.

[0041] During the pulse diagnosis process, the pulse data is collected by the pulse sensor 14, and the collected data can be compared with the data entered in advance in the database to achieve the purpose of diagnosis; after the pulse sensor 14 collects the data, the airbag is first deflated, and the arm can be taken out at this time, and then the components are controlled to return to the initial position.
