Abstract
Abstract A hypodermic needle assembly adapted for covering and uncovering the needle by relative lateral movement between a closure member and the needle. The needle has an enlargement hub portion. An elongated closure is disposed in adjacent relationship with respect to the needle and has an elongated slot which permits insertion of the needle into the closure and removal of the needle therefrom. The closure may engage the needle hub for resisting undesired removal of the closure. A closure strip is displaceably secured in overlying relationship with respect to the slot so as to provide a sterile needle. Pilot means may be provided adjacent the closure slot to facilitate insertion of the needle into the slot. An indicator may be provided to facilitate determination of closure orientation.
