Abstract
A syringe for use with a carpule and needle is provided. The syringe comprises: (i) a holder for accepting the carpule, the holder comprising at least two linearly disposed first mating members; (ii) a plunger for engagement with the holder; and (iii) a shell for slidably housing the holder, the shell having a distal aperture and a proximal aperture, with a bore therebetween, the shell comprising at least one integral biased member proximate to the proximal aperture, the biased member having a second mating member proximate to a distal end, for mating with the first mating member, such that in a first position, the needle is housed within the shell and in a second position, the needle extends at least partially from the shell.
