INJECTOR

摘要

An injector including a syringe arranged along a longitudinal axis, a removable cover for removable engagement with the syringe and a cover removal assembly including 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 the longitudinal axis and an inner portion which includes at least one engagement portion which is engagable with the removable cover, whereby axial movement of the inner portion in the cover disengagement direction removes the removable cover from the syringe, at least one of the outer portion and the inner portion being configured such as to provide an axially floating lost motion engagement between the outer portion and the inner portion.

1. An injector comprising:
a syringe arranged along a longitudinal axis; a removable cover for removable engagement with 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; andan inner portion which includes at least one engagement portion which is engagable with said removable cover, whereby axial movement of said inner portion in said cover disengagement direction removes said removable cover from said syringe, at least one of said outer portion and said inner portion being configured such as to provide an axially floating lost motion engagement between said outer portion and said inner portion, whereby axial movement of said outer portion in said cover disengagement direction produces corresponding axial movement of said inner portion in said cover disengagement direction along at least a portion of said axial travel path, the length of said portion of said axial travel path being a function of the relative axial positioning of said removable cover and said syringe.
