Abstract

Described is a cartridge cap with a feature that aides in the removal of a battery cap from a drug infusion pump. The proximal end of the cartridge cap includes a recess on an inner surface that receives a tab on a distal end of the battery cap. To remove the battery cap from the drug infusion pump, the proximal end of the cartridge cap is placed over the distal end of the battery cap such that the recess in the cartridge cap receives the tab on the battery cap. The cartridge cap is then rotated counterclockwise until the battery cap is removed from the drug infusion pump.
