Abstract:
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, 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.
