Cartridge system for delivery of medicament

摘要

A cartridge system for delivery of medicament includes as membrane placed between two disk magnets that are housed within pump body inserts. The pump body inserts having flow channels and fluid openings are between two inlet/outlet members. The inlet/outlet members each having a fluid outlet component and fluid openings are securely engaged to two reservoirs containing fluid medicaments.
