## Abstract

A safety body fluid collector keeps a needle, held by a needle holder, in place frictionally with the use of an elastomeric O-ring. After use, the body fluid collector is inverted and placed over a discard container. Downward pressure on finger grips on the collector causes a tube of a disposal member, attached to the lid of the container, to press against the O-ring, unseating the O-ring and freeing the needle holder with the needle from the frictional hold of the O-ring. The needle holder and needle then drop into the discard container and when the discard container is full, it is discarded.

## Claims

### Claim 1

A body fluid collector system comprising:
(a) a needle holder with a needle;
(b) a cylinder;
(c) an O-ring seated within said cylinder and in contact with said needle holder to frictionally hold said needle holder, with said needle, in place when the fluid is extracted from the body;
(d) a bushing slidingly fitted onto said needle holder;
(e) means for releasing the frictional hold on said needle holder by said O-ring; and
(f) a discard container for temporary storage of, and disposal of used needles.

### Claim 2 (depends on 1)

The body fluid collector system of claim 1 wherein said needle comprises a first end for injection into the body and second end upon which a collecting vial is emplaced and wherein said body fluid collector system further comprises a removable first cap placed over said first end and a removable second cap placed over said second end for safety in transporting, storing and handling of said body fluid collector prior to use.

### Claim 3 (depends on 2)

The body fluid collector system of claim 2 further comprising a sheath positioned over said second end.

### Claim 4 (depends on 3)

The body fluid collector system of claim 3 wherein said needle holder further comprises a ridge against which said O-ring is seated.

### Claim 5 (depends on 4)

The body fluid collector of claim 4 wherein said O-ring comprises aa elastomeric material and has a substantially square cross section with rounded outer corners.

### Claim 6 (depends on 5)

The body fluid collector system of claim 5 wherein said cylinder comprises an end section with an end lip and said bushing comprises a protuberance which is in contact with said end lip.

### Claim 7 (depends on 6)

The body fluid collector system of claim 6 wherein said cylinder comprises finger grips for the application of finger pressure to release said needle from said O-ring.

### Claim 8 (depends on 1)

The body fluid collector system of claim 1 wherein said container comprises a body section, a lid, with an opening therein and a transparent disposal member positioned on said lid over said opening.

### Claim 9 (depends on 8)

The body fluid collector system of claim 8 wherein said disposal member comprises a large diameter tube and a smaller diameter tube which projects past said large diameter tube, so that when said body fluid collector is placed over said disposal member and finger pressure is applied to said finger grips, said smaller diameter tube presses against said O-ring, dislodging said O-ring from its seat and onto said bushing and freeing said needle holder and needle to fall through said opening into said container.

### Claim 10 (depends on 9)

The body fluid collector system of claim 9 wherein said disposal tube further comprises a cap for covering said disposal member when said container is full or when needles are not being discarded.

### Claim 11 (depends on 8)

The body fluid collector system of claim 8 wherein said needle comprises a first end for injection into the body and second end upon which a collecting tube is emplaced and wherein said body fluid container system further comprises a removable first cap placed over said first end and a removable second cap placed over said second end for safety in transporting, storing and handling of said body fluid collector prior to use.

### Claim 12 (depends on 11)

The body fluid collector system of claim 11 further comprising a collapsible sheath positioned over said second end.

### Claim 13 (depends on 12)

The body fluid collector system of claim 12 wherein said needle holder further comprises a ridge against which said O-ring is seated.

### Claim 14 (depends on 13)

The body fluid collector of claim 13 wherein said O-ring comprises an elastomeric material and has a substantially square cross section with rounded outer corners.

### Claim 15 (depends on 1)

The body fluid collector system of claim 1 wherein said cylinder comprises an end section with an end lip and said bushing comprises a protuberance which is in contact with said end lip.

### Claim 16 (depends on 15)

The body fluid collector of claim 15 wherein said cylinder comprises finger grips for the application of finger pressure to release said needle from said O-ring.

### Claim 17

A body fluid collector comprising:
(a) a needle;
(b) a needle holder holding said needle;
(c) a cylinder,
(d) an O-ring set within said cylinder and in contact with said needle holder to frictionally hold said needle holder, with said needle, in place when the fluid is extracted from the body;
(e) means for releasing the frictional hold by said needle holder by said O-ring.
