Injection device including a casing, a syringe carrier located within a proximal end of the casing and being movable along a longitudinal axis of the device between a stowed position and a needle insertion position, a drive assembly located within a distal end of the casing and being movable by an insertion driver in order to move the syringe carrier and a loaded syringe from a stowed position to a needle insertion position; a first formation fixed relative to the casing and a second formation fixed relative to an insertion tube of the drive assembly, the first and second formations defining a plurality of stop positions for the insertion tube relative to the casing, spaced along the direction of said longitudinal axis, to prevent significant rearward movement of the insertion tube along said axis when a plunger of a firing cartridge is released from a reaction assembly of the cartridge.

Injection device

A needle protection device () for protecting a needle has a needle carrier () for carrying said needle () and being translatable along a longitudinal axis X between a first, deployed, position (D) and a second, protected, position (P); a shuttle () surrounding said needle (); a hub () for receiving the needle carrier (); a sleeve () being rotatable around each of said needle carrier (), said shuttle () and said hub (); a first driving mechanism () between said needle carrier () and said shuttle () to cause axial displacement of said shuttle () in a first direction (A) between a first, retracted position R and a second, deployed position Ds upon axial displacement of the needle carrier () along axis X; and a second driving mechanism () between said needle carrier () and said sleeve () to cause axial displacement of the carrier () in said first direction (A) upon rotational displacement of the sleeve ().
