HYPODERMIC NEEDLE SYSTEM ACTIVATION MECHANISM

摘要

A needle hypodermic system and method for reducing the incidence of infections due to administering fluids by injection or for reducing the risk of surface contamination of an aspirated sample of blood or other bodily tissue in humans or animals is provided. The hypodermic needle system may include a needle with a plug or film disposed over or within its hollow bore to substantially prevent bacteria, fungi and/or other organisms/contaminants, which may be present on the exterior surface to be penetrated, from adhering to the inner surfaces of the needle's channel or become trapped in the needle bore. A second stylet or needle may be deployed to pierce or push aside the plug.

主权项

1. A hypodermic needle system comprising:
a first needle having a base, a bore and a distal end, the bore opening at the distal end; a plug disposed in the bore, the plug being ejectable from the distal end; an insert advanceable in the bore of the first needle; and a spacer clip disposable to limit advancement of the insert in the first needle to prevent the insert from ejecting the plug.
