An autoinjector for dispensing a liquid product includes a housing; a product container arranged in the housing, particularly, a syringe comprising a displaceable piston; a drive member; a first spring which acts on the drive member and the piston to dispense the product from the container; signal element releasably axially coupled with the drive member so that the signal element is transported in the dispensing direction as said drive member is displaced; and a second spring, which exerts a spring force on the signal element against the dispensing direction and is tensioned as the signal element is transported in the dispensing direction. When the signal element is released or detached from the axial coupling, the second spring causes the signal element to accelerate opposite the dispensing direction and strike against a signal stop and generate an acoustic and/or tactile signal.

Medicament container carrier

A medicament container carrier comprising a proximal section having a first diameter, a distal section having a second diameter less than the first diameter, and at least one resilient beam arranged in the proximal section and having a beam head protruding radially to form a third diameter. The at least one beam has a non-deflected position in which the third diameter is less than the first diameter and a deflected position in which the third diameter is substantially equal to the first diameter.

Cartridge retainer for an injection device

A cartridge retainer comprises a sleeve having a distal end a proximal end and a longitudinal axis extending between the distal end and the proximal end. One or more tabs extend radially from the sleeve toward the longitudinal axis and are configured to radially deflect away from the longitudinal axis. One or more deformable members extend axially from the distal end of the sleeve toward the one or more tabs and are configured to deform in a longitudinal direction toward the distal end.

Medicament Container Holder
20190060579 · 2019-02-28 ·

The present invention relates to a medicament container holder (10) comprising a body (12) adapted to receive a medicament container (14), the body (12) comprising proximally directed tongues (38) at its proximal end, engagement elements (42) arranged at the proximal end of the tongues (38), directed inwards, which engagement elements (42) are arranged to engage a neck portion (46) of the medicament container (14); wherein the tongues (38) deflect radially outwards when engaged by a needle shield (16) of said medicament container (14). The invention is characterised in that said tongues (38) with said engagement elements (42), engage with said neck portion (46) of said medicament container (14) for preventing the medicament container (14) from moving in a proximal direction relative the medicament container holder (10), when disengaged with said needle shield, wherein said tongues (38) are in a stressed state when in engagement with said neck portion (46).

NEEDLE INSERTION AND RETRACTION MECHANISM
20190030240 · 2019-01-31 ·

A system and method are provided for preventing a sharp stick hazard from a needle tip of an automatic injector device. In some embodiments, a skin contact surface of the device is attached to an injection site, for example by an adhesive. Optionally a locking mechanism holds a needle extended into an injection site. A body of the device is optionally movably attached to the skin contact surface. Pulling the body away from the injection site optionally moves the body with respect to the skin contact surface. Movement of the body with respect to the skin contact surface optionally moves interlinked parts of the locking mechanism, releasing the locking mechanism.
