Compression hemostasis requires the use of an electric pneumatic hemostat, which is often used in surgery, ICU, anesthesia, emergency department and other occasions, especially in limb surgery.

[0003] The electric pneumatic hemostatic device controls the air pressure in the pathway through a microcomputer, so that the cuff connected to the pathway changes accordingly, thereby exerting pressure on the limbs to control the blood flow in the limbs, thereby achieving the effect of stopping bleeding.
