Needle sheath remover assembly
First Claim
1. A needle sheath remover assembly for a medicament delivery device, axially elongated in a proximal and a distal direction, comprising:
- a cap configured for removable attachment to a housing of the medicament delivery device, the cap comprising a second blocking device and a biasing device;
a sheath grabber connected to the cap and configured for engaging a needle sheath of a medicament container in the medicament delivery device, the sheath grabber comprising a second stop device and an engaging device;
wherein the cap and sheath grabber are axially movable in relation to each other and are configured for interaction with each other such that upon removal of the cap from the housing, the sheath grabber is able to engage and remove the needle sheath;
movement of the sheath grabber is restricted by interaction between the biasing device and the engaging device such that the sheath grabber is biassed to engage the needle sheath; and
movement of the cap relative to the sheath grabber is restricted by interaction between the second blocking device and the second stop device such that the cap, the sheath grabber, and the needle sheath are removable from the medicament delivery device.
