Abstract

A sterile surgical-thermal drape (10) is provided. The sterile surgical-thermal drape (10) includes a sterile surgical drape (12) that maintains a sterile field and a thermal device (14) attached (16) to the sterile surgical drape (12) for regulating the body temperature of a patient (32). The thermal device (14) has an external surface, and is operable to provide convective heating or cooling to a patient.

Claims

1. A sterile surgical-thermal drape comprising:

a sterile surgical drape for use during surgery operable to maintain a sterile surgical field; and

a thermal device attached to the sterile surgical drape operable to regulate the body temperature of a patient, wherein the thermal device is operable to provide at least one of convective heating and cooling to the patient by directing a hot or cold fluid towards the patient, the thermal device comprising a fluid passageway operable to conduct at least one of a gas and a liquid, wherein the thermal device further comprises a woven material, and wherein the woven material forms a portion of a sidewall of the fluid passageway.

3. The sterile surgical-thermal drape of claim 1 wherein the sterile surgical drape further comprises one of a fenestration and an incise for exposing a portion of the patient'"'"'s body.

4. The sterile surgical-thermal drape of claim 1 further comprising a barrier attached between the sterile surgical drape and the thermal device and enclosing the sterile surgical drape for maintaining the sterility of the sterile surgical drape.

5. The sterile surgical-thermal drape of claim 3 further comprising a fluid pocket operable to receive fluids passing through the one of a fenestration and an incise.

2. A sterile surgical-thermal drape comprising:

a sterile surgical drape for use during surgery operable to maintain a sterile surgical field;

a fluid passageway that is operable to conduct at least one of a gas and a liquid;

a thermal device attached to the sterile surgical drape operable to regulate the body temperature of a patient and wherein the thermal device is operable to provide at least one of convective heating and cooling to the patient, wherein the thermal device further comprises a woven material, and wherein the woven material forms a portion of a sidewall of the fluid passageway;

one of a fenestration and an incise for exposing a portion of the patient'"'"'s body during surgery; and

a barrier attached between the sterile surgical drape and the thermal device and enclosing the sterile surgical drape for maintaining the sterility of the sterile surgical drape.

6. The sterile surgical-thermal drape of claim 2 further comprising a fluid pocket operable to receive fluids passing through the one of a fenestration and an incise.
