Abstract

The invention relates to a precise medicine infusion system. The precise medicine infusion system comprises a precise medicine infusion pump, a driving circuit, a shell capable of being implanted in the body, a soft medicine bag and a pressure switch chamber with certain air pressure. The outer wall of the soft medicine bag can be squeezed when the air pressure in the pressure switch chamber is released, liquid medicine in the soft medicine bag is pumped out through the precise medicine infusion pump, and the liquid medicine can be precisely infused into the body of a patient. The precise medicine infusion system has the advantages of being simple and reasonable in structure, small in size, free of maintenance, capable of allowing medicine to be added multiple times, capable of being implanted in the body, wide in application range, low in power, efficient, safe and accurate in use, convenient to use, and the like.

Description
