ABSTRACT:
Intravenous needle sheaths are described which can be used safely for exposing the recapping the sharp tips. The sheaths comprise partially slit concentric or eccentric elastic tubes with special markings, the proximal ends of which are anchored permanently to the hubs of various kinds of needles, and the distal ends of which guide the tips safely through combinations of rigid and elastic parts in all positions of needle exposure, use and resheathing.
