Abstract
A user-wearable patch pump system for delivery of insulin or other medicament can include a patch pump having a reusable drive unit and a replaceable and refillable cartridge. The cartridge can selectively attach to and be detached from the drive unit. The cartridge can initially be inserted onto the drive unit in a first orientation at an angle to the drive unit and then be rotated to align the cartridge with the drive unit and lock the cartridge in place on the drive unit to form the patch pump.

An ambulatory infusion pump system including an ambulatory infusion pump, the ambulatory infusion pump comprising:
- a reservoir configured to contain a medicament;
- a pump housing having a front surface and a rear surface and a drive mechanism configured to be actuated to cause medicament to be delivered from the reservoir to a user;
- and
- a top housing configured to be selectively attachable to the pump housing, wherein the top housing is configured to be aligned in a first non-parallel orientation with respect to the pump housing and the top housing is configured to be rotated with respect to the pump housing in a first direction to lock the top housing onto the pump housing in a second orientation, wherein the front surface of the top housing is aligned generally parallel to and coplanar with the front surface of the pump housing.
An ambulatory infusion pump system including an ambulatory infusion pump, the ambulatory infusion pump comprising:
- a reservoir configured to contain a medicament;
- a first portion having a front surface and a rear surface and a drive mechanism configured to be actuated to cause medicament to be delivered from the reservoir to a user;
- and
- a second portion configured to be selectively attachable to the first portion, wherein the second portion is configured to be aligned in a first non-parallel orientation with respect to the first portion and the second portion is configured to be rotated with respect to the first portion in a first direction to lock the second portion onto the first portion in a second orientation, wherein the front surface of the second portion is aligned generally parallel to and coplanar with the front surface of the first portion.
