Abstract:
The present invention relates to a feedback mechanism (20) for an injection device that is configured to deliver a medicament to a user. The feedback mechanism (20) has a biasing member that is arranged to apply a force to a delay element (30), and the delay element (30) is configured to deform and/or break under the force. The feedback mechanism (20) also includes an indicator (24) arranged to generate user feedback after the delay element (30) is deformed and/or broken. The delay element (30) is configured to deform and/or break at a time after the force is applied by the biasing member to create a delay before the user feedback is generated.
Abstract:
A drug delivery device comprising a housing, said housing containing a syringe, wherein the syringe comprises: a container containing a liquid medicament, said container comprising an aperture at a distal end thereof and through which said liquid medicament can be dispensed; a stopper within said container, said stopper moveable between a first longitudinal position and a second longitudinal position relative to the container, to cause dispensing of said liquid medicament through said aperture; and at least one identifying means identifying the liquid medicament.
Abstract:
The present invention relates to a medicament delivery device (10). The medicament delivery device (10) comprises a housing (11), a needle (12) and a needle actuating mechanism (14). The needle actuating mechanism (14) is configured to rotate the needle (12) relative to the housing (11) to move the needle (12) from a stowed position to a primed position. The present invention also relates to a method of operating a medicament delivery device (10).
Abstract:
The present invention relates to a medicament delivery device. The medicament delivery device comprises a housing, a needle, a medicament delivery mechanism and an actuator. The needle is moveable from a retracted position, wherein the needle is fully received in the housing, to an extended position, wherein the needle protrudes out of the housing. The medicament delivery mechanism comprises a reservoir and dispensing member each disposed in the housing, first and second biasing members, and first and second locking members. 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 the retracted position to the 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.
