摘要
A needle assembly for medical or surgical use is disclosed, such as for hemodialysis. A representative needle assembly comprises an outer needle assembly and an integral needle tip protector. A representative outer needle assembly comprises: an outer needle comprising: a first lumen; a first aperture with a sharp needle tip at a first distal end of the outer needle; and a second aperture arranged opposite the first aperture. In another embodiment, the outer needle has a longitudinal slot and the integral needle tip protector includes a sliding connector which is slidable in the longitudinal slot. The integral needle tip protector is arranged within the first lumen and moveable between a retracted configuration and an extended configuration, and comprises: a needle tip cover arranged to shield the sharp needle tip in the extended configuration, the needle tip cover having a smooth or beveled distal surface forming a blunt tip.
