Abstract

A portable body heating/cooling system and method of use are provided for thermal treatment of selected body portions such as joints, muscles and the like, a reservoir being insulated for containing hot/cold fluid, an elongated and flexible thermal pad having one surface formed by conductive and flexible tubular conduits for conforming to the selected body portion and for producing thermal treatment by the flow of fluid through the tubular conduits, the tubular conduits being connected with the reservoir by non-collapsible supply and return tubes, and a pump preferably battery operated and preferably located in the reservoir for continually circulating fluid from the reservoir through the tubular conduits and back to the reservoir, the thermal pad being equipped with a retainer for securing the thermal pad in contact with the selected body portion, the supply and return tubes preferably being accordion-like in configuration to assure constant circulation of fluid through the thermal pad, the conduit also preferably being corrugated.

Claims

1. A portable body heating/cooling apparatus for thermal treatment of selected body portions such as joints, muscles and the like, comprising

an insulated reservoir for containing hot/cold fluid,

a thermal pad substantially formed by corrugated conduit means configured to allow substantially rapid fluid circulation within the entire conduit means,

non-collapsible supply and return tubes interconnected between the reservoir and the conduit means in the pad, and

pump means for continually circulating fluid from the reservoir through the conduit means and back to the reservoir,

said corrugated conduit means comprising parallel portions formed from a thermally conductive material corrugated on both interior and exterior surfaces and forming alternating ridges and valleys on the exterior surface thereof with corresponding valleys and ridges on the interior surface thereof, the material being sufficiently flexible for conforming to the selected body portion and for producing thermal treatment by the flow of fluid past the valleys and ridges of the entire interior conduit surface, the tubular portions being respectively connected to the supply and return tubes and to each other, the entire pad being elongated for application in extended or flat relation to the body or wrapped around a body joint or limb with the conduit means in direct thermally conductive relation with the heated or cooled circulating fluid therein and the selected body portion to be treated, whereby the use of the corrugated conduit means in combination with the pump means provides rapid and direct thermal change transfer from the circulating heated/cooled fluid across the conduit means to the selected body portion in contact therewith.

2. The portable body heating/cooling apparatus of claim 1 wherein the pump means is battery operated and located in the reservoir.

3. The portable body heating/cooling apparatus of claim 1 further comprising retainer means for securing the thermal pad in contact with the selected body portion.

4. The portable body heating/cooling apparatus of claim 2 wherein the supply and return tubes are formed with an accordion-like configuration to assure constant circulation of fluid through the conduit means of the thermal pad.

5. The portable body heating/cooling apparatus of claim 1 wherein the supply and return tubes are formed with an accordion-like configuration to assure constant circulation of fluid through the conduit means of the thermal pad.

6. The portable body heating/cooling apparatus of claim 1 wherein the conduit means are sufficiently rigid to permit bending without collapse, the exterior ridges of the conduit corrugation proportionally limiting total direct surface area contact of the corrugated conduit means with the body portion being treated and the exterior valleys of the conduit corrugation acting to collect and trap water condensation resulting from ambient environmental humidity.

7. In a method employing a portable body heating/cooling system for thermal treatment, the steps comprising

storing hot/cold fluid in an insulated reservoir,

arranging a thermal pad in thermally conductive relation with a selected body portion to be treated, wherein the thermal pad is substantially formed by corrugated conduit means configured to allow substantially rapid fluid circulation within the entire conduit means,

interconnecting the reservoir and the conduit means in the pad by non-collapsible supply and return tubes, and

continually pumping the fluid in circulation from the reservoir through the conduit means and back to the reservoir in order to assure continual thermal treatment of the selected body portion,

said conduit means comprising parallel tubular portions formed from a thermally conductive material corrugated on both interior and exterior surfaces and forming alternating ridges and valleys on the exterior surface thereof with corresponding valleys and ridges on the interior surface thereof, the material being sufficiently flexible for conforming to the selected body portion and for producing thermal treatment by the flow of fluid past the valleys and ridges of the entire interior conduit surface, the conduit portions being respectively connected to the supply and return tubes, the entire pad being elongated for application of the pad in extended or flat relation to the body or wrapped around a body joint or limb with the conduit means in direct thermally conductive relation with both the heated or cooled circulating fluid therein and the selected body portion, whereby the use of the corrugated conduit means in combination with the continual pumping of the fluid provides rapid and direct thermal change transfer from the circulating heated/cooled fluid across the conduit means to the selected body portion in contact therewith.

8. The method of claim 7 further comprising retainer means for securing the thermal pad in contact with the selected body portion.

9. The method of claim 8 wherein the supply and return tubes are formed with an accordion-like configuration to assure constant circulation of fluid through the conduit means of the thermal pad.

10. the method of claim 7 wherein the corrugated conduit means are sufficiently rigid to permit bending without collapse, the exterior ridges of the conduit corrugation proportionally limiting total direct surface area contact of the corrugated conduit means with the body portion being treated and the exterior valleys of the conduit corrugation acting to collect and trap water condensation resulting from ambient environmental humidity.

11. The method of claim 7 wherein the supply and return tubes are formed with an accordion-like configuration to assure constant circulation of fluid through the conduit means of the thermal pad.
