## Abstract

A disposable back table collection device having a container with an open end and at least one layer of an absorbent material positioned within the container. The open end of the container is sealed with a cover containing a leak resistant injection site. The invention also may have a second layer of an absorbent material positioned on top of the cover with an aperture therein corresponding to the location of the injection site. In use, a syringe is inserted into the injection port and the syringe is drained. The fluid from the syringe is absorbed into the layer of absorbent material. When the syringe is removed, the injection port has sufficient elastic "memory," or shape retaining characteristics, to return to its original position, thereby insuring a leak resistant seal. Further, there is no splashing while the syringe is either inserted or removed because any droplets of fluid that may escape from the syringe are absorbed into the absorbent material on the top of the device. The result is a leak resistant, splash resistant disposable back table collection device.

## Claims

### Claim 1

A back table collection device for draining a syringe, comprising:
a plastic container with an open end;
at least one layer of an absorbent foam positioned within said plastic container;
a layer of an elastic material sealing said open end of said plastic container;
a hole positioned in the center of said layer of elastic material, said hole being substantially leak resistant in its relaxed state and stretching to substantially the size of the tip of said syringe in its expanded state; and
a second layer of an absorbent material completely covering said layer of elastic material for substantially absorbing any droplets of fluid that may escape from said syringe.

### Claim 2 (depends on 1)

The back table collection device of claim 1 wherein said layer of an absorbent material comprises large pore foam.

### Claim 3 (depends on 2)

The back table collection device of claim 2 wherein said layer of large pore foam comprises reticulated ester filter foam.

### Claim 4 (depends on 1)

The back table collection device of claim 1 wherein said second layer of an absorbent material comprises polyurethane open cell foam.

### Claim 5 (depends on 1)

The back table collection device of claim 1 wherein said layer of an elastic material comprises thermoplastic rubber.

### Claim 6 (depends on 1)

The back table collection device of claim 1 wherein said layer of an elastic material is heat sealed to said container.

### Claim 7 (depends on 1)

The back table collection device of claim 1 further comprising a waterproof cover layer positioned between said elastic layer and said second layer of an absorbent material.

### Claim 8 (depends on 7)

The back table collection device of claim 7 wherein said waterproof cover layer comprises high density polyethylene fibers.

### Claim 9 (depends on 1)

The back table collection device of claim 1 wherein said container has sufficient clearance between said elastic layer and said layer of an absorbent material to permit the entry of said syringe tip into said hole without said syringe tip contacting said layer of absorbent material.

### Claim 10 (depends on 1)

The back table collection device of claim 1 wherein said container has tapered sides to resist tipping.

### Claim 11 (depends on 1)

The disposable back table collection device of claim 1 wherein said container further comprises a bottom end and wherein said bottom end has a layer of adhesive tape positioned thereon.
