Abstract

The invention discloses a spring hand-muscle developer. The spring hand-muscle developer comprises an elastic shell, a signal control assembly and at least one first spring with conductivity. The signal control assembly comprises a circuit board. The circuit board is provided with an element for controlling a reminding signal to be started and a metal hole, one end of the first spring is connected with the elastic shell, and the other end of the first spring is in selective contact with the metal hole in the circuit board. When the force with which the elastic shell is grasped reaches a set value, the first spring is in contact with the metal hole, and the reminding signal is started; when the force with which the elastic shell is grasped is smaller than the set value, the first spring is not in contact with the metal hole, and the reminding signal is stopped. By means of the spring hand-muscle developer, the force for grasping the hand-muscle developer can be effectively controlled according to starting or stopping of the reminding signal, and therefore the flowing speed of blood during blood drawing can be controlled.

Description

technical field [0001] The invention belongs to the field of medical aids, in particular to a spring grip, which is mainly used to assist 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 effect of preventing vasospasm. However...
