Abstract

The present disclosure relates to a medicament delivery device. The medicament delivery device comprises a housing, a dispensing mechanism and an actuator. The housing has first and second portions. The dispensing mechanism comprises a reservoir disposed in the housing. The dispensing mechanism is operable to dispense medicament from the reservoir when the reservoir contains medicament. The first portion of the housing comprises a distal end and the second portion is moveable towards the distal end from an initial position to a primed position. The dispensing mechanism is rendered inoperable when the second portion is in the initial portion. The actuator is actuatable to operate the dispensing mechanism when the second portion is in the primed position.

Dependent claims

A medicament delivery device comprising:

a housing comprising a first portion and a second portion, the first portion of the housing having a distal end and the second portion of the housing being moveable towards the distal end from an initial position to a second position, wherein when the second portion of the housing is in the second position, the medicament delivery device is in a primed position;
a dispensing mechanism that comprises a reservoir disposed in the housing, the reservoir being a flexible bag, wherein the dispensing mechanism is operable to dispense a medicament from the reservoir when the reservoir contains the medicament;
and
an actuator, wherein actuation of the actuator is impeded such that the dispensing mechanism is rendered inoperable when the second portion is in the initial position, and the actuator is actuatable to operate the dispensing mechanism when the second portion is in the second position.
