Abstract

A fluid containment pouch is provided that includes a first layer of material having a first thermal characteristic and a second layer of material having a second thermal characteristic. The first layer of material is thermally compatible with a patient covering upon which it is to be thermally bonded. Thermal bonds between the fluid containment pouch and the patient covering form fluid containment channels that retain expelled body fluids during a patient's operation to help maintain a sterile operating environment.

Claims (20)

1. A fluid containment pouch comprising:

a first layer of material having a first thermal characteristic, the first layer of material being thermally compatible with a patient covering;

a second layer of material having a second thermal characteristic that is different than the first thermal characteristic of the first layer, the second layer of material positioned adjacent the first layer of material to form a pouch material, at least one first section of the pouch material positioned over a second section of pouch material to form at least one channel having at least one outer edge, the second layer of material being heat sealed together proximate the at least one outer edge;

the first section of the pouch material having a first opening; and

the second section of the pouch material having a second opening, the second opening being at least in part aligned with the first opening, wherein the first opening and the second opening provide access through the fluid containment pouch to a patient during a surgical procedure.

2. The fluid containment pouch of claim 1 , wherein the patient covering is at least one of an incise and a patient drape.

3. The fluid containment pouch of claim 1 ,

wherein the at least one first section of pouch material is folded over the second section of pouch material to form the at least one channel.

4. The fluid containment pouch of claim 1 , wherein the first and second openings are centrally located within the respective first and second section.

5. The fluid containment pouch of claim 1 , further comprising:

a port formed in one of the first and second sections configured and arranged to provide a passage for fluid contained in the at least one channel to be removed from the fluid containment pouch.

6. A fluid containment assembly comprising:

a patient drape configured and arranged to cover at least a portion of a patient; and

a fluid containment pouch made from a pouch material having a first layer of a first material and a second layer of a second material, the first material having a first melting point and the second material having a second melting point, the second melting point of the second material being different than the first melting point of the first material, the first layer of the fluid containment pouch thermally coupled to the patient drape, at least one first section of the pouch material positioned over a second section of pouch material to form at least one channel having at least one outer edge, the second material of the first section and the second material of the second section being heat sealed together proximate the at least one outer edge.

7. The fluid containment assembly of claim 6 , wherein the at least one first section is folded over the second section of pouch material to form the at least one channel.

8. The fluid containment assembly of claim 6 , wherein the first and second material layers are one of polyurethane, polyethylene, polypropylene and polyester.

9. The fluid containment assembly of claim 6 , further comprising an incise.

10. The fluid containment assembly of claim 6 , wherein the fluid containment pouch is coupled around a cover opening in the patient drape.

11. The fluid containment pouch assembly of claim 10 , wherein the fluid containment pouch includes a pouch opening aligned with the cover opening.

12. The fluid containment pouch assembly of claim 6 , wherein the fluid containment pouch and the patient drape form fluid channels to hold a patient's bodily fluids.
