The invention provides a delivery mechanism for an autoinjector comprising: a first drive member configured to drive a first component in an axial direction; a second drive member configured to drive a second component in an axial direction; and a release mechanism configured to control a sequence of release of the first drive member and the second drive member, wherein the release mechanism is positioned at least partially within the first or second drive member.

Delivery mechanism for an autoinjector

The invention provides a drive mechanism for an autoinjector, configured to be coupled to a drug containing portion to form a complete autoinjector, the drive mechanism comprising: a housing (); a drive means coupled to the housing, the drive means comprising a resilient member (); a retaining means coupled to the housing, the retaining means () engaging the drive means in a first position to retain the resilient member in a deformed condition, and releasing the drive means in a second position; and a coupling means () for coupling with a drug containing portion (). The drug containing portion retains the drive means in a second deformed condition when the retaining means is in the second position, the drive means storing enough energy in the second deformed condition to drive needle insertion and/or drug delivery.

Drive assembly for an autoinjector and a method of assembling an autoinjector

An auto-injector apparatus includes a flexible container containing a liquid medicant, a needle communicated with a container, a housing with a container being received in the housing, a pump disposed in the housing and positioned to engage the flexible container and expel the medicant from the container through the needle upon relative movement between the pump and the container, and a main drive spring operably associated with the needle to extend the needle from a first needle position wherein the needle is completely received in the housing to a second needle position wherein the needle protrudes from the housing. The pump may be a roller.

Auto-injector apparatus

A resettable training device and method for training a user on the operation of an auto-injector for dispensing a medicament are provided. The user can operate the training device to simulate an auto-injector operation and then reset the training device to repeat the injector operation. The training device includes a housing, a cover member slidably received within the housing between a retracted operative position and an extended inoperative position, a spring member for biasing the cover member into the extended position, an actuation assembly that controls the movement of the cover member from the retracted position to the extended position in response to activation of the trainer by the user, a safety pin, and in some embodiments at least one releasable locking assembly to prevent movement of the cover member from the extended position to the retracted position.
