Abstract

A safety guard adapted for use with a Huber needle assembly that includes a main body, a pair of butterfly wings extending outwardly from the main body and a needle.

Claims

1. A safety guard adapted for use with a needle assembly that includes a main body, a pair of butterfly wings extending outwardly from the main body and a needle extending at an angle from an end portion of the main body comprising:

an elongated substantially hollow shield, the shield having open ends and an elongated slot extending between the open ends;

a spring connected to the assembly and the shield such that the slot and the needle are substantially parallel; and

,

a fastener adapted to position the shield in a first position substantially parallel to the main body, and to permit the shield to pivot to a second position through spring force to surround and/or trap the needle.

2. A safety guard adapted for use with a needle assembly that includes a main body, a pair of butterfly wings extending outwardly from the main body and a needle extending at an angle from an end portion of the main body comprising:

a shield having opposed open ends;

a coiled spring surrounding the needle and connected between the main body end portion and the shield; and

,

a fastener adapted to position the shield in a first position relative to the butterfly wings such that the shield does not impede contact of the butterfly wings with a patient target surface, and to permit the shield to slide to a second position through spring force to surround and/or trap a distal end portion of the needle.

3. A combination needle assembly and needle safety guard comprising:

a main body;

a needle extending at an angle from an end portion of the main body;

a shield having opposed open ends and having a hollow portion slidably positioned around the needle;

a pair of folding legs connected between the main body and the shield; and

, a fastener adapted to position the shield in a first position to maximize the needle exposure, and to permit the shield to slide along the needle to a second position through unfolding of the legs to surround and/or trap a distal end portion of the needle.
