Abstract
The electrochemical pump unit of mesh combined electrode of the present invention is connected to a drug injection container for operation, when it is connected to the power supply, the cathode (or anode) enters into electrochemical reaction with the electrolyte of the superabsorbent material layer through the mesh electrode to release a first gas, the first gas flows through the screen meshes of mesh electrode immediately without obstruction loss; the anode (or cathode) enters into electrochemical reaction with the electrolyte on the opposite side of superabsorbent material layer through the plane electrode to release a second gas, the second gas flows through the inter fibrous small space/channels of superabsorbent material layer and the screen meshes of mesh electrode; as the first gas and the second gas increase, the piston is pushed, and the medicament is pushed.
