Abstract

Abstract A convective hyperthermia article is disclosed. The article has a generally U-shaped hollow body with two legs and a cross piece connecting the legs. The article is dimensioned to lie adjacent a patient's body and extend a substantial length thereof. A set of air holes is spaced on at least the underside of the article. The article also has a receptacle opening to detachably receive an air hose from a heat source. Heated air is received in the interior of the hyperthermia article and directed through the air holes onto the patient's body. The article is economically produced so as to be disposable.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 145 words
A light-weight disposable convective hyperthermia article for use in controlling a patient's body temperature, said article having a generally U-shaped air filled hollow body having an interior and an exterior and comprised of two legs and a cross piece connecting the legs, said article dimensioned and adapted to lie adjacent the patient's body and extend a substantial length thereof and made of a sufficiently flexible material to permit folding into a compact unit for storage and to permit folding and shaping to accommodate the patient, further said article having a receptacle opening to detachably receive an air hose from a heat source for receiving heated air into the interior of the U-shaped body and a set of spaced air holes in the legs and in the cross piece of the U-shaped body adapted for passing the heated air from the interior to proximate the patient.
Claim 2
Dependent Claim 145 words
A light-weight disposable convective hyperthermia article for use in controlling a patient's body temperature, said article having a generally U-shaped air filled hollow body having an interior and an exterior and comprised of two legs and a cross piece connecting the legs, said article dimensioned and adapted to lie adjacent the patient's body and extend a substantial length thereof and made of a sufficiently flexible material to permit folding into a compact unit for storage and to permit folding and shaping to accommodate the patient, further said article having a receptacle opening to detachably receive an air hose from a heat source for receiving heated air into the interior of the U-shaped body and a set of spaced air holes in the legs and in the cross piece of the U-shaped body adapted for passing the heated air from the interior to proximate the patient.
Claim 3
Dependent Claim 27 words
The hyperthermia article of claim 1 wherein the U-shaped hollow body is made of non-woven fabric having a thin plastic coating covering at least one side thereof.
Claim 4
Dependent Claim 19 words
The hyperthermia article of claim 1 wherein the receptacle opening is in an approximate center of the cross piece.
Claim 5
Dependent Claim 25 words
The hyperthermia article of claim 3 wherein the receptacle opening in the U-shaped body is positioned on an outside side wall of the cross piece.
Claim 6
Dependent Claim 34 words
The hyperthermia article of claim 1 further having a semi-rigid reinforcing collar interposed in the cross piece and the receptacle opening being positioned in the collar to better hold and retain the air hose.
Claim 7
Dependent Claim 35 words
The hyperthermia article of claim 2 wherein the air holes in the U-shaped hollow body are spaced to provide a hole density of from about one per square inch to about five per square inch.
Claim 8
Dependent Claim 40 words
The hyperthermia article of claim 6 wherein the air holes are positioned substantially uniformly in an approximate inside half of the U-shaped hollow body thereby adapted to ensure a flow of heated air to a restricted part of the patient.
Claim 9
Dependent Claim 22 words
The hyperthermia article of claim 7 wherein the air holes have a diameter of from about 30 mils to about 250 mils.
Claim 10
Dependent Claim 43 words
The hyperthermia article of claim 1 wherein the legs of the U-shaped body are from about four feet to about six feet in length and the cross piece of the U-shaped body is from about two feet to about three feet in length.
Claim 11
Dependent Claim 118 words
A light-weight disposable convective hyperthermia article for use in controlling a patient's body temperature, said article having a generally U-shaped hollow body having an interior and an exterior and having two legs and a cross piece connecting the legs, said article dimensioned to lie adjacent the patient's body and extend a substantial length thereof, further said article having a semi-rigid reinforcing collar interposed in the cross piece with a receptacle opening positioned therein to detachably receive an air hose from a heat source for receiving heated air into the interior of the U-shaped body and a set of air holes spaced in the U-shaped hollow body adapted for passing heated air from the interior to proximate the patient.
Claim 12
Dependent Claim 118 words
A light-weight disposable convective hyperthermia article for use in controlling a patient's body temperature, said article having a generally U-shaped hollow body having an interior and an exterior and having two legs and a cross piece connecting the legs, said article dimensioned to lie adjacent the patient's body and extend a substantial length thereof, further said article having a semi-rigid reinforcing collar interposed in the cross piece with a receptacle opening positioned therein to detachably receive an air hose from a heat source for receiving heated air into the interior of the U-shaped body and a set of air holes spaced in the U-shaped hollow body adapted for passing heated air from the interior to proximate the patient.
Claim 13
Dependent Claim 26 words
