ABSTRACT:
A disposable syringe comprising two slidably collapsible cylindrical portions. The first cylindrical portion forms part of a standard disposable syringe which has been slightly altered to include one or more integral protrusions. The second cylindrical portion is slidably movable along the first cylindrical portion from an extended position in which it completely envelopes the needle portion of the disposable syringe to a retracted position in which the needle is fully exposed. Means are provided on the two cylindrical portions to prevent the retraction of the second cylindrical portion after the disposable syringe has been used so as to prevent any reuse of the disposable syringe.
