Abstract
Apparatus and method for filling, or refilling, the internal reservoir of a medication infusion system, wherein filling or refilling is permitted only when a means for injecting medication is properly positioned relative to the reservoir. Prior to filling or refilling, a pressure integrity check can be made to help assure that injected medication enters the reservoir without leakage. Additionally, flushing of a portion or all of the medication reservoir can be accomplished if desired. Medication is introduced to and is stored in the reservoir at a pressure below ambient body pressure.
