ABSTRACT:
A disposable hypodermic syringe is provided which contains storage and breakage means for the needle of the syringe to prevent the needle from causing injury, damage or infection to a person handling the syringe or garbage containing the syringe after it is used and disposed of. In one form, the piston of the syringe is molded with an elongated cavity in its end, into which cavity the needle of the syringe may be inserted and broken off the needle receptacle. The cavity may be such as to frictionally retain the end of the needle therein to facilitate breakage and prevent its removal. In another form, the mount for the needle is constructed to facilitate breakage and to retain the broken needle in the cavity receptacle.
