Abstract

Drug delivery devices and related methods of assembly are disclosed. The drug delivery device may include a main housing having an interior surface defining an enclosed space, and an exterior surface releasably attachable to a patient. A container may be disposed in the enclosed space and include a reservoir containing a drug and a stopper. A drive assembly may also be disposed in the enclosed space and configured to move the stopper through the reservoir to expel the drug from the reservoir. The drive assembly may include a rotational power source and a gear module. The gear module may include a mounting plate and a plurality of gears rotatably connected to the mounting plate. Furthermore, the mounting plate may be separate from the main housing.

Claims12

Dependent claims

A drug delivery device comprising:

a housing releasably attachable to a patient;
a container disposed at least partially within the housing;
a delivery member comprising a distal end configured to be inserted into a skin of the patient;
an insertion mechanism configured to, upon activation, move the delivery member from an initial position, wherein the distal end of the delivery member is disposed at least partially within the housing, to a deployed position, wherein the distal end of the delivery member is disposed at least partially outside of the housing for insertion into the skin of the patient;
and
a drive assembly comprising a rotational power source and at least one gear operably coupled with the rotational power source, the drive assembly being configured to activate the insertion mechanism and move a drug out of the container and into the patient via the delivery member.
