Abstract

A needle protector having a body, a needle hub and a needle. The body includes a first end and a second end. The body consists of a hollow elongated cylinder defined by a continuous wall having a channel extending between the first and second ends. The continuous wall defines a recess adjacent the first end. The needle hub is movably mounted on the body. The needle hub has an external portion, an internal portion and a tracking member extending between the external portions. The tracking member is positioned in the channel. The external portion includes a single locking arm adapted to be received by the recess and the second end. The needle is mounted in the internal portion of the needle hub. Movement of the needle hub from the first end to the second end results in corresponding movement of the needle into the body until the locking arm engages the second end thereby preventing movement of the needle hub and the needle from the second end to the first end of the body.

Claims

1. A needle protector, comprising:

a body having a first end and a second end, said body having a continuous wall defining a channel extending substantially between said first and second ends, said continuous wall defining a recess having a recess edge adjacent to said first end opposite said channel, said continuous wall defining an edge adjacent to said second end;

a needle hub movably mounted on said body, said needle hub having an external portion, an internal portion and a tracking member extending between said external and internal portions, said tracking member positioned in said channel, said external portion including a single locking arm having an elongated flexible member extending longitudinally from said external portion and an inwardly projecting locking member including a chamfer and a locking edge, and wherein said external portion further including a plurality of circumferentially extending gripping members to prevent slippage of a user'"'"'s fingers during use and movement of the needle hub; and

a needle mounted on said internal portion of said needle hub, whereby movement of said needle hub from said first end to said second end results in corresponding movement of said needle into said body until said locking edge of said locking arm irreversibly engages said end edge of said second end thereby preventing movement of said needle from said body;

wherein said external portion circumferentially surrounds said body and said locking arm is located within said recess when said needle hub is at said first end of said body.

2. The invention of claim 1, wherein said internal portion defines a chamber for receiving fluid from said needle.

3. The invention of claim 2 wherein the needle includes a pointed end and a hollow shaft in communication with the chamber.

4. The invention of claim 1, wherein said body is comprised of a substantially hollow elongated cylinder.

5. The invention of claim 1, wherein said first end includes an end cap defining a needle opening for receiving said needle.

6. The invention of claim 1, wherein said locking arm is integral with said external portion.
