Abstract

A guard for a right angular winged infusion needle includes a trough like body which receives and protects the needle and a clip portion at one end of the guard extending at right angles to the trough like body snugly grips the wing attachment on the needle to maintain the needle in assembled relationship with the guard.

Claims

1. A guard for a right angle winged infusion needle comprising

an elongated substantially rectangular body including spaced longitudinal side walls, a longitudinal back wall joined to the side walls and a pair of end walls joined to the side and back walls, said body being open along its length away from said back wall, and

a clip attachment carried by said body near one end thereof and including a wall substantially contiguous with one end wall of the body and extending outwardly of the opening of the body and further including a laterally spaced pair of somewhat resilient fingers adjacent to the longitudinal side walls of the body and extending outwardly thereof in spaced substantially parallel opposing relationship to the wall of said clip, whereby the shank of a right angle winged infusion needle may be held protectively in said body while a part of the wing of the needle is being held in the clip attachment.

2. A guard for a right angle winged infusion needle as defined in claim 1, and a marginal flange on the side walls and one end wall of the body extending around three sides of the opening of the body and said fingers being fixed on said flange and projecting somewhat laterally outwardly of the longitudinal side walls, and said wall of the clip attachment also projecting somewhat laterally outwardly of said longitudinal side walls and being connected with said flange.

3. A guard for a right angle winged infusion needle as defined in claim 2, and a pair of gripping ribs on the wall of said clip attachment in opposing substantially parallel relationship to said fingers, and a single stiffening rib on the wall of said clip attachment at its surface away from said fingers and substantially midway between and parallel to the gripping ribs and substantially at the transverse center of said body.

4. A guard for a right angle winged infusion needle as defined in claim 3, and said guard being molded as a unit from plastics material.

5. A guard for a right angle winged infusion needle comprising

an elongated approximately rectangular body which is open along one side and including opposite side longitudinal walls, a back longitudinal wall and a pair of end walls,

a marginal flange on said body adjacent to its open side and being contiguous with said longitudinal side walls and one end wall and projecting outwardly of such walls approximately perpendicular thereto, and

a clip attachment on said body substantially at one end thereof and extending outwardly from the open side of the body and away from said back wall, the clip attachment including a clip wall which is contiguous with one end wall of the body and forms substantially a continuation thereof, the clip wall projecting somewhat laterally outwardly of the longitudinal side walls of the body and being joined with said marginal flange and having spaced gripping elements formed on one face thereof, and the clip attachment further including a pair of spaced fingers united with said flange and being in spaced opposing substantially parallel relationship to the clip wall and also being in spaced opposing relationship to the gripping elements and being substantially coextensive lengthwise with the clip wall away from said flange and away from the open side of said body.
