Abstract
A drug delivery device for delivery of medicament having a delivery pump system and a cartridge system, the delivery pump system operating electromagnetically by driving two disk magnets that are housed within pump body inserts of the cartridge system. The displacement of the magnets and an elastomer membrane placed between the magnets of the cartridge system results in a volumetric change within two reservoirs and the flow of medicaments. The medicament flows from the reservoirs to the inlet/outlet members via the pump body inserts and discharged to a patient user's body through an infusion set.
