ABSTRACT:
An improved IV infusion set of the type comprising a length of tube with a hollow needle at one end. The improvement comprises a sheath slidably disposed on the tube and adapted to be slid over the needle to cover the needle after use. The sheath is particularly adapted for use with IV infusion sets of the type comprising outwardly projecting flexible wings adjacent the end of the tubing with the needle, commonly referred to as "butterfly" infusion sets. The sheath comprises a hollow generally tubular body having a slot extending longitudinally from the forward end of the body partway toward the rearward end, and a cutout in the body at the rearward end of the slot. The slot allows the wings to pass to the cutout to allow at least a portion of the sheath to slide past the wings to cover the needle. The cutout engages the wings, locking the body in its position covering the needle. The sheath may be temporarily secured, for example by friction fit with some part of the infusion set, so that it does not interfere with the use of the infusion set.
