Systems and methods allowing for reservoir filling and infusion medium delivery
First Claim
1. A system, comprising:
- an infusion medium container for holding an infusion medium;
a plunger disposed at least partially within the infusion medium container, the plunger being moveable within the infusion medium container, the plunger comprising;
a plunger body for forcing the infusion medium out of the infusion medium container; and
a plunger septum; and
a transfer guard having a transfer element for piercing the plunger septum and for providing a path between the infusion medium container and a reservoir container to allow the infusion medium to be transferred from the infusion medium container to the reservoir container, the transfer guard configured to be attachable to and detachable from the reservoir container to allow removal of the reservoir container from the system.

Abstract
A system includes a durable portion with a durable housing and a separable disposable portion with a disposable housing that selectively engage with and disengage from each other. The disposable housing secures to a patient and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient or with an infusion medium may be part of the disposable portion to allow for disposal after a prescribed use. A reservoir for holding the infusion medium may be part of the disposable portion, and may be supported by the disposable housing. The durable portion may include other components such as electronics for controlling delivery of the infusion medium from the reservoir, and a drive device including a motor and drive linkage.

16. A method for using a system, the system comprising an infusion medium container for holding an infusion medium, a plunger that is disposed at least partially within the infusion medium container, and a transfer guard, the plunger having a plunger body and a plunger septum, the plunger body for forcing the infusion medium out of the infusion medium container, the plunger septum capable of being pierced to allow the infusion medium to flow through the plunger body, the transfer guard having a transfer element the transfer guard configured to be attachable to and detachable from a reservoir container to allow removal of the reservoir container from the system, the method comprising:
-
piercing the plunger septum with the transfer element of the transfer guard to provide a path between the infusion medium container and the reservoir container; and moving the infusion medium container relative to the reservoir container to cause the infusion medium to be transferred from the infusion medium container to the reservoir container through the plunger body. - View Dependent Claims (17, 18, 19)

25. A method of manufacturing a system, the method comprising:
-
providing an infusion medium container for holding an infusion medium; disposing a plunger at least partially within the infusion medium container, the plunger being moveable within the infusion medium container, the plunger comprising; a plunger body for forcing the infusion medium out of the infusion medium container; and a plunger septum; providing a transfer guard having a transfer element for piercing the plunger septum and for providing a path between the infusion medium container and a reservoir container to allow the infusion medium to be transferred from the infusion medium container to the reservoir container; and configuring the transfer guard to be attachable to and detachable from the reservoir container to allow removal of the reservoir container from the system.
