First Claim
1. A fluid infusion system comprising:
- a pump housing having a reservoir cavity, the reservoir cavity having a rim and coupling features, the coupling features formed on an interior face of the reservoir cavity, the pump housing further being sized to be pocketable;
a reservoir being removable from the reservoir cavity, the reservoir having an open end;
a cap being removably coupled to the pump housing, the cap having corresponding coupling features, an exterior surface and a tab, the corresponding coupling features defined to couple the cap to the pump housing, the tab defined as a ridge that extends away from the exterior surface, the tab further having a port to accommodate fluid flow from the reservoir, the port defining an axis of rotation such that torque applied to the tab about the axis of rotation disengages the coupling between the cap and the pump housing, anda guard being removably coupled to the pump housing, the guard having a slot defined between two arms joined at a flexible hinge, the slot defined to immobilize rotation of the tab about the axis of rotation, the two arms each having a snap disposed on an end opposite the flexible hinge.

Abstract
The fluid infusion system is disclosed that includes a pump housing that has a reservoir cavity and is designed to be pocketable. The reservoir cavity has a rim and helical coupling features formed on an interior face of the reservoir cavity. The fluid infusion system further has a reservoir that is removable from the reservoir cavity and the reservoir also has an open end. A removable cap coupled to the pump housing is also included in the fluid infusion system. The cap has corresponding coupling features, an exterior surface and a tab. The corresponding coupling features are defined to couple the cap to the pump housing while the tab is defined as a ridge that extends away from the exterior surface. The tab further has a port to accommodate fluid flow from the reservoir where the port defines an axis of rotation such that torque applied to the tab about the axis of rotation disengages the coupling between the cap and the pump housing. Further included in the infusion system is a guard that is removably coupled to the pump housing. The guard has a slot defined to immobilize rotation of the tab about the axis of rotation.

11. A system to retain a fluid medication reservoir to a medication pump housing, comprising:
-
a pump housing having a reservoir cavity, the reservoir cavity having a rim and coupling features, the helical coupling features formed on an interior face of the reservoir cavity, the coupling features further having a dimple formed on the rim, the pump housing further being sized to be pocketable; a reservoir being removable from the reservoir cavity, the reservoir having an open end; a cap being removably coupled to the pump housing, the cap having corresponding coupling features, an exterior surface, and a tab, the corresponding coupling features defined to couple the cap to the pump housing, the corresponding coupling features including a snap defined on an edge of the cap that removably interfaces with the dimple on the pump housing, the tab defined as a ridge that extends away from the exterior surface, the tab further having a port to accommodate fluid flow from the reservoir, the port defining an axis of rotation such that torque applied to the tab about the axis of rotation disengages the coupling between the cap and the pump housing, and a guard being removably coupled to the pump housing, the guard having a slot defined between two arms joined at a flexible hinge, the slot defined to immobilize rotation of the tab about the axis of rotation, the two arms each having a snap disposed on an end opposite the flexible hinge. - View Dependent Claims (16, 17, 18, 19)
