Injector
First Claim
1. An injector comprising:
- a syringe arranged along a longitudinal axis and having a forward end and a rearward end;
a removable cover for removable engagement with said forward end of said syringe; and
a cover removal assembly comprising;
an outer portion which is engagable by a user and is movable axially in a cover disengagement direction along an axial travel path with respect to said longitudinal axis; and
an inner portion which includes at least one engagement portion which is engagable with a rearward end of said removable cover, whereby axial movement of said inner portion in said cover disengagement direction removes said removable cover from said syringe,said outer portion and said inner portion being movable relative to one another in an axial direction along said longitudinal axis during use,said inner portion also including a rearward facing surface which lies up against a forward surface located at said forward end of said removable cover, which is opposite said rearward end of said removable cover, and wherein said rearward facing surface is configured such that said forward end of said removable cover limits the movement of said rearward facing surface in a direction opposite to said cover disengagement direction, thereby limiting the position of said at least one engagement portion relative to said removable cover in a direction opposite to said cover disengagement direction upon mutual engagement of said inner portion and said removable cover.
