A device that is used to fill an elastomeric infusion pump system chamber with a prescribed medicated solution, to create the pressure required to expand the elastic chamber and the subsequent force that infuses the solution into the patient/user when connected. The device typically holds a syringe prefilled with the solution, and has a handle or lever that is used to push the syringe plunger inward to force the solution into the elastomeric chamber. This device is typically designed for use by a layperson. This is a reusable device.
