US 11,452,820 B2 · Medicament delivery device

Abstract

The present disclosure relates to a medicament delivery device. The medicament delivery device comprises a housing, a needle, a medicament delivery mechanism and an actuator. The actuator is moveable relative to the housing from an initial position to an intermediate position such that the actuator exerts a force on the first locking member to urge the first locking member from a locked state to an unlocked state wherein the first biasing member moves the needle from a retracted position to an extended position. The actuator is moveable relative to the housing from the intermediate position to a second position such that the actuator exerts a force on the second locking member to urge the second locking member from a locked state to an unlocked state wherein the second biasing member moves the dispensing member within the housing to dispense medicament from the reservoir when the reservoir contains medicament.

Dependent claims

A medicament delivery device comprising:

a housing;
a needle moveable from a retracted position, in which the needle is fully received in the housing, to an extended position, in which the needle protrudes out of the housing;
a medicament delivery mechanism comprising a reservoir and a dispensing member each disposed in the housing, first and second biasing members, and first and second locking members;
and
an actuator moveable relative to the housing from an initial position to an intermediate position such that the actuator exerts a force on the first locking member to urge the first locking member from a locked state to an unlocked state in which the first biasing member moves the needle from the retracted position to the extended position,
wherein the actuator is moveable into the housing from the intermediate position to a second position such that the actuator exerts a force on the second locking member to urge the second locking member from a locked state to an unlocked state in which the second biasing member moves the dispensing member within the housing to dispense medicament from the reservoir when the reservoir contains the medicament.
