Abstract

An infusion pump system. The system includes a reusable housing assembly, a disposable housing assembly, a tab portion comprising a female latching feature, and an exit, the exit connected to a reservoir; and a fluid connector including a body portion including a slot, a plug portion slidably connected to the body portion, the plug portion including a fluid path and a disc, the disc configured to seat within the slot, a catch feature located on a first end of the body portion and configured to interact with the disposable housing assembly, a male latching feature located on a second end of the body portion, the male latching feature configured to interact and lock onto the female latching feature, wherein force applied to the plug portion may overcome a threshold force and unseat the disc from the slot wherein the plug portion moves with respect to the body portion.

Claims
