A medicament injection device comprising a main body arranged to receive a medicament cartridge; a needle carrier carrying a needle, wherein the needle carrier is axially movable with respect to the main body; and a rotatable cap at a distal end of the device, wherein the cap is removably coupled to the needle carrier, a releasable arrangement between the main body and the cap comprising a guide element and a slotted link, wherein the slotted link is arranged to cause the guide element to follow a predefined path at least partly in an axial direction during rotational movement of the cap, thereby causing the needle carrier to move axially towards a proximal end of the device as the cap is rotated up to a predefined point, wherein the main body comprises a medicament cartridge holder comprising the guide element depending therefrom for engagement with the cap.

Medicament injection device

A medicament injection device comprising: a main body configured to receive a medicament cartridge, a needle sleeve axially movable with respect to the main body, a needle holder holding a needle, and a displacement element coupled to the needle holder and disengageably coupled to the needle sleeve; wherein, upon axial displacement of the needle sleeve by a predefined distance in a proximal direction, the needle carrier and needle are displaced axially in a proximal direction.

A medicament injection device is provided. The device includes a main body configured to receive a medicament cartridge sealed with a penetrable holder. The device can further include a needle holder holding a needle, a needle sleeve arranged to be axially movable with respect to the main body, and a retainer coupled to the needle holder and to the needle sleeve. The retainer can be axially movable with respect to the main body along the main axis of the device. Upon displacement of the needle sleeve and the retainer by a predefined distance towards a proximal end of the main body, the needle holder and the needle can be displaced axially towards the proximal end of the main body and decouple from the retainer. The needle sleeve can be configured to disengage from the needle holder upon displacement of the needle sleeve.
