ABSTRACT:
A multiple purpose protective hypodermic needle cap which: is initially supplied by a manufacturer of a disposable hypodermic needle syringe: first, to protect the hypodermic needle during shipping and storing, until the syringe is ready for its medical use; second, after the syringe is utilized, the top of the cap, which has a preformed cavity, having a pocket depth serving as a gage, to receive and to position a predetermined length of the hypodermic needle, before it is bent, is positioned over the end portion of the hypodermic needle and then this cap is used as a tool to bend back this pointed, sharp end portion of the hypodermic needle beyond ninety degrees; third, the cap is moved clear of this bent end portion, then rotated and placed back over this bent end portion, and beyond; and fourth, the cap is moved over this bent end portion, until the pointed and sharp tip end of this bent end needle portion, radially expands, in a one way latching motion, into a receiving cavity, having an engagement lip to contact the pointed and sharp tip end if any removal is attempted. Both the cavity and engagement lip are initially formed and provided during the manufacture of this disposable hypodermic needle syringe. Thereafter, this utilized disposable hypodermic needle syringe is safely disposed of, because this multiple purpose protective hypodermic needle cap is locked on and cannot be removed, without completely destroying the needle and syringe.
