Abstract

The invention discloses a mechanical wrist developer. The mechanical wrist developer comprises an elastic shell, and a signal control assembly, a first conductive part and a second conductive part which are arranged in the elastic shell. The signal control assembly comprises a circuit board. An element for controlling a prompting signal for turning on and a plated-through hole are arranged on the circuit board. The first conductive part makes alternative contact with the second conductive part. The second conductive part is fixed to the circuit board and makes contact with the plated-through hole. When force of holding the elastic shell reaches a set value, the first conductive part makes contact with the second conductive part, and the mechanical wrist developer is turned on according to the prompting signal; when force of holding the elastic shell is smaller than the set value, the first conductive part does not contact with the second conductive part, and the mechanical wrist developer is turned off according to the prompting signal. The mechanical wrist developer is turned on or off according to the prompting signal, the strength and frequency of holding the mechanical wrist developer can be effectively controlled, and the blood flowing speed during blood drawing can be controlled.

Description

technical field [0001] The invention belongs to the field of medical auxiliary supplies, and in particular relates to a mechanical gripper, which is mainly used for assisting blood donation. Background technique [0002] When donating blood, in order to speed up the blood flow when drawing blood and prevent vasospasm, the staff usually provides a grip ball to the blood donor. Existing grip balls are mainly circular or egg-shaped balls made of highly elastic materials such as PU. After the blood donor grasps the grip ball, due to the effect of its high-elastic material, the grip ball will rebound quickly, and the blood donor can feel the pressure of the grip ball on the fingers. Generally, you can feel numbness and heat in the palm of your hand after grasping it several times. This is because the grip ball can effectively stimulate the various acupoints on the palm when the palm is continuously grasped, thereby promoting blood circulation, speeding up blood flow and The eff...
