Abstract
A medicament reservoir module for attachment to a pumping and control module includes a conventional medicament vial closed at one end by a penetrable stopper, which is inserted to operate as a piston in the vial. A hollow needle, attached to an adaptor that releasibly connects to the stopper, pierces the stopper and provides a medicament flow path via a slack length of flexible tubing from the vial to a peristaltic pump in the pumping and control module. A housing supports the vial, encloses the adaptor, hollow needle, and slack tubing, and releasibly connects to the pumping and control module. Thereby, a detachable reservoir module is provided, permitting quick and reliable resupply of medicament directly from filled standard vials.
