An infusion pump assembly is disclosed. The infusion pump assembly includes a locking tab and a pump barrel inside a pump barrel housing, where the pump barrel accommodates a reservoir assembly. The reservoir assembly includes a reservoir and a plunger rod. The infusion pump assembly also includes a locking disc at a terminus of the pump barrel. The locking disc includes a clearance hole for the plunger rod. The locking disc also includes at least one locking tab notch in close proximity with the locking tab. The locking tab is in moveable engagement with the locking tab notch, and the reservoir moves the locking tab from a locked position to an unlocked position when the plunger rod is inserted through clearance hole. The locking disc rotates upon torque being applied to the reservoir assembly, the locking disc rotating from a non-loaded position to a loaded position with respect to the plunger rod and a drive screw.
What is claimed is: 1. An infusion pump assembly comprising:a locking tab;a pump barrel inside a pump barrel housing, said pump barrel accommodates a reservoir assembly comprising a reservoir, a plunger rod and a locking hub fluidly connected to said reservoir, said locking hub comprising:at least t
What is claimed is: 1. An infusion pump assembly comprising:a locking tab;a pump barrel inside a pump barrel housing, said pump barrel accommodates a reservoir assembly comprising a reservoir, a plunger rod and a locking hub fluidly connected to said reservoir, said locking hub comprising:at least two locking hub alignment tabs, said locking hub alignment tabs aligning with at least two reservoir alignment tabs when said locking hub is fluidly connected to said reservoir;a locking disc at a terminus of said pump barrel in close proximity with said locking tab, said locking disc comprising:a clearance hole for said plunger rod;at least one locking tab notch; andat least two reservoir tab openings for mating with said at least two reservoir alignment tabs on said reservoir; anda hub and battery end cap, said end cap comprising:an opening to said pump barrel, said pump barrel opening being complementary to said locking hub alignment tabs; anda first alignment feature, said first alignment feature complementary to a second alignment feature on said reservoir,wherein when said first and second alignment features are aligned, said locking hub alignment tabs are aligned with said hub and battery cap opening, andwherein the loading of said reservoir assembly provides alignment of said reservoir alignment tabs with said reservoir tab openings and said plunger rod with said clearance hole, andwherein said locking tab is in moveable engagement with said locking tab notch, andwherein said reservoir moves said locking tab from a locked position to an unlocked position when said plunger rod is inserted through said clearance hole, andwherein said locking disc rotates upon torque being applied to said reservoir assembly, said locking disc rotating from a non-loaded position to a loaded position with respect to said plunger rod and a drive screw.
