Abstract

A safety shield apparatus is disclosed which includes a needle having a distal portion defining a longitudinal axis which is angularly displaced relative to a longitudinal axis defined by a proximal portion of the needle. A shield is mounted with the needle and extensible, via a tubular needle guide movable along the needle, between a retracted position and an extended position. The apparatus may include a needle hub configured to support the proximal portion of the needle. The needle hub can include an appendage which may have at least one opening to facilitate manipulation thereof. A distal end of the shield can be attached to a planar contact surface. The shield may also include a latch engageable with the needle.

Claims

1. A safety shield apparatus comprising:

a needle shield having a planar contact surface;

a pad having a first surface mountable to the planar contact surface and a second surface configured for engagement with a body surface.

2. The safety shield apparatus according to claim 1 wherein said pad is made from a foam material.

3. The safety shield apparatus according to claim 1 wherein said pad is made from a felted material.

4. The safety shield apparatus according to claim 1 wherein said pad is made from a breathable material.

5. The safety shield apparatus according to claim 1 wherein said pad is made from a material configured for wicking moisture.

6. The safety shield apparatus according to claim 1 wherein said pad is impregnated with an antimicrobial agent.

7. The safety shield apparatus according to claim 1 wherein at least one of said surfaces includes a thin film coating disposed thereon.

8. The safety shield apparatus according to claim 7 wherein said thin film coating is perforated.

9. The safety shield apparatus according to claim 1 wherein said pad comprises:
