ABSTRACT:
A sliding slit elastomeric needle sheath is described for preventing needle-stick injuries from hollow-bore steel needles attached to trailing tubular assemblies used for giving intravenous infusions or withdrawing blood. The sheath comprises a slit elastomeric tube with a leading end and a trailing end, the trailing end of which slides over the silastic tubing in standard butterfly and phlebotomy assemblies, or onto the leading end of vacutainer needle hubs, until the trailing end of the sheath locks with compression onto the hub of the needle used for venepuncture. The mid-portion of the sheath is surrounded by a securely attached puncture-resistant scabbard. The slit elastic tube is stretched by manual traction to enclose or expose the venepuncture needle. The leading end of the sheath includes a flexible tender with a tab for guiding the sharp needle tips safely and accurately through combinations of rigid and slit elastic parts to prevent needle-stick injuries during and after withdrawal of the needle from the vein of a patient by a user whose hands operate in customary positions.
