Abstract
This invention relates to a combination needle shield/needle guard device for a hypodermic syringe with a needle permanently attached to the front end of the syringe barrel. This needle shield/needle guard device is positively locked to the syringe barrel and can perform two functions: first, function as a needle shield which encloses and prevents contamination of a sterile needle and secondly, function as a needle guard which can slide on the surface of the syringe barrel, such that the needle can be uncovered and re-covered from behind the needle point, thereby providing a safety feature in that medical personnel can avoid direct contact with a needle point during the process of uncovering or re-covering the needle. More particularly, an unused sterile hypodermic needle is enclosed within the needle shield/needle guard device which protects the needle from contamination. Exteriorization of the needle from inside the needle shield/needle guard device occurs after an aperture is created by pulling off a tab at the front end of the needle shield/needle guard device and then retracting the needle shield/needle guard device on the syringe barrel, permitting the needle to exteriorize through the aperture. After the needle has been used for a medical procedure, extending the needle shield/needle guard device on the syringe barrel permits re-coverage of the used needle from behind the needle point, so that medical personnel avoid direct contact with the pointed end of a contaminated needle.
