Abstract

The brace includes one or more air inflatable bladders equipped with an automatic, regulated, and removable air pressure regulation valve, where different valves have different release settings. In addition, a removable, thermally responsive material for hot and cold therapy may be placed in a pocket between the outer and inner material for the brace. The inside surface of the brace is comprised of an absorbent material that absorbs body perspiration, and then releases it to the atmosphere. The brace is placed around the injured area of the patient so that the air bladder(s) lies against the injured area. Air is then introduced into the air bladder via an air inlet valve, forming a compressive force on the body part in contact. In another embodiment of the brace, pneumatic compression is obtained by the use of two or more overlapping air inflatable bladders, each having an air regulation valve with a different pressure release level, wherein the pressure is higher distally and lower ventrally.

Claims

1. A brace having a shape to match a predetermined body part, comprising means forming a flexible pocket, a thermal bladder in said pocket that selectively provides heating or cooling, a pressure bladder in said pocket, first valve means associated with said pressure bladder for introducing a gas therein from a gas source, and second valve means associated with said pressure bladder for automatically maintaining the gas pressure in said bladder at a predetermined level said second valve means being readily replaceable with a plurality of other second valve means respectively having a plurality of different predetermined levels.

2. The brace of claim 1, wherein said pocket is comprised of a first flexible sheet of insulating material and a flexible second sheet of absorbent material adapted to be placed in contact with the body part, means connecting said sheets to form said pocket.

3. The brace of claim 2, and further comprising means for selectively closing said pocket.

4. The brace of claim 1, wherein said brace further comprises a second pocket and a second pressure bladder in said second pocket.

5. The brace of claim 1, wherein said thermal bladder includes an outer shell comprised of flexible, liquid-pervious material sealed along a plurality of lines to create an array of cells, and a thermally responsive liquid in said cells.

6. The brace of claim 5, wherein said thermally responsive medium is a water/isopropyl alcohol mixture.

7. The brace of claim 1, wherein said brace has a shape to match a persons knee.

8. A brace having a shape to match a predetermined body part comprising means forming first and second flexible pockets, a thermal bladder in each of said pockets that selectively provides heating or cooling, first and second pressure bladders respectively in said pockets, first valve means associated with each of said pressure bladders for introducing a gas therein from a gas source, second valve means associated with said first pressure bladder for automatically maintaining the gas pressure in said first bladder at a predetermined first level, third valve means associated with said second pressure bladder for automatically maintaining the gas pressure in said second bladder at a predetermined second level said second and third valve means being readily replaceable with a plurality of other second and third valve means respectively having a plurality of different predetermined levels.
