An injection device is disclosed comprising a plunger for expressing medicament from a syringe and a delivery mechanism arranged in use to provide a forward biasing force to urge the plunger from a first rearward position to a second forward position to express a dose from the syringe. A latch arrangement is provided that releasably holds the plunger against the force of the delivery mechanism. The latch arrangement comprising at least two resilient segments which define opposing sections of an aperture within which a rearward end of the plunger is retained in the rearward position. A trigger is provided for releasing the plunger in use, the trigger being arranged to outwardly deflect at least one of the resilient segments such that the aperture is expanded to release the rearward end of the plunger. A method of manufacturing the injection device is also enclosed.

Injection device with safe trigger function

A device for delivery of a medicament from a container () having an outlet () at a distal end of the container () and a stopper () for containing the medicament in the container (). The device comprises a housing (), a drive element () arranged to move in the distal direction to cooperate with the container (), a drive mechanism comprising a trigger component (), the drive mechanism being arranged to hold the drive element () in a starting position and to move the drive element () in the distal direction from the starting position upon displacement of the trigger component () from a working position to a firing position, an interlock component () received in the housing () and arranged for movement with respect to the housing () from a first position to a second position, and at least one flexible locking member () arranged to cooperate with a stop face () associated with the housing () to prevent displacement of the trigger component () to the firing position when the interlock component () is in the first position. Movement of the interlock component () towards the second position causes bending of the flexible locking member () away from the stop face () to allow displacement of the trigger component () to the firing position.

Medicament delivery devices

An injection device () for injection of a medicament from a pre-filled container () having a container body () for containing the medicament, a needle () disposed at a distal end of the container body (), a removable needle shield () and a stopper () for expelling medicament from the container (), the device comprising a housing () for housing the container (), a plunger () for driving the stopper () of the container () in a distal direction to expel the medicament, and a priming mechanism having an operating member () which is movable with respect to the housing (). The priming mechanism is arranged to release the needle shield () from the needle () and to move the container body () in a proximal direction with respect to the plunger () upon movement of the operating member () from a first position to a second position during an operating sequence of the device.
