## Abstract

The current invention is a syringe and swab system for a syringe having a plunger, a barrel, a needle hub, a needle, a needle safety cover, and a swab attached to the distal end of the needle safety cover for placing over an injection site to apply pressure and a vial for holding fluid that may be utilized with the swab.

## Claims

### Claim 1

A needle guard system for covering a syringe needle after use, comprising:
a needle guard, said needle guard including a first end configured for attaching said needle guard to a syringe needle and a distal end opposite the first end;
said needle guard including a swab portion, a protective guard portion, and a hinge;
said swab portion being located at the distal end of said needle guard, said hinge being located between said protective guard portion and the first end, and said protective guard portion being located between said hinge and said swab portion;
said needle guard being configured such that after use of the syringe needle, said protective guard portion swings at said hinge along an arc to cover the syringe needle, with the syringe needle being separated from said swab portion by said protective guard portion; and
a vial for holding a liquid attached to and in communication with said swab portion wherein said liquid is applied to said swab portion as desired.

### Claim 2 (depends on 1)

The needle guard system of claim 1 further includes a removable cover for covering said swab portion.

### Claim 3 (depends on 2)

The needle guard system of claim 2 wherein said swab removable cover is attached to said needle guard.

### Claim 4 (depends on 3)

The needle guard system of claim 3 wherein said swab portion is made from foam.

### Claim 5

A syringe and swab system for applying pressure and absorption to an injection site from a needle after an injection, comprising:
a syringe, the syringe having a plunger, a barrel, a needle hub, and a needle;
a needle guard, said needle guard including a first end and a distal end, the first end attaching said needle guard to said syringe, the distal end being opposite the first end;
said needle guard including a swab portion, a protective guard portion, and a hinge;
said swab portion being located at the distal end of said needle guard, said hinge being located between said protective guard portion and the first end, and said protective guard portion being located between said hinge and said swab portion;
said needle guard being configured such that after an injection, said protective guard portion swings at said hinge along an arc to cover said needle, with said needle being separated from said swab portion by said protective guard portion; and
a vial for holding a liquid attached to and in communication with said swab portion wherein said liquid is applied to said swab portion as desired.

### Claim 6 (depends on 5)

The syringe and swab system of claim 5, wherein said syringe and swab system further includes a removable cover for covering said swab portion.

### Claim 7 (depends on 6)

The syringe and swab system of claim 6 wherein said swab removable cover is attached to said needle guard.

### Claim 8 (depends on 7)

The syringe and swab system of claim 7 wherein said swab portion is made from foam.

### Claim 9 (depends on 8)

The syringe and swab system of claim 8 wherein said swab portion is detachable from said protective guard portion.
