MEDICAMENT DELIVERY DEVICE HAVING AN ACTIVATING MECHANISM
First Claim
1. Medicament delivery device (1) comprising an activating mechanism, wherein the activating mechanism comprises:
- a hollow injection needle (5),a cartridge (2) containing a dosage of a medicament,a cartridge carrier (6) comprising at least one resilient arm (6.1) for holding the cartridge (2),a removable needle cap (7) for covering the injection needle (5), anda drive element (8) adapted to couple with the cartridge (2),wherein the cartridge (2) is retained in a position spaced apart from the injection needle (5) in a proximal direction (P) by at least one resilient arm (6.1) when the medicament delivery device (1) is in an initial position (P1), andwherein by removing the needle cap (7), the cartridge (2) is releasable to be pushed into a distal direction (D) by the drive element (8) with respect to the cartridge carrier (6),whereinan inner surface of a proximal end of the removable needle cap (7) bears against an outer surface of the at least one resilient arm (6.1), and whereinan outer surface near the proximal end of the removable needle cap (7) bears against an inner surface of the cartridge carrier (6).
