Abstract
Abstract A therapeutic apparatus is provided for treating a bodily injury or ailment by applying compression and a high or low temperature fluid to the injury or ailment. The apparatus has a cuff through which hot or cold water from a remote reservoir is continuously circulated under pressure when operating in one mode. When operating in the other mode, the cuff is filled with compressed air at ambient temperature and sealed.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
87 words
An apparatus for treating bodily injuries or ailments comprising: a bladder applied to a treatment region of the body; a means for circulating treatment fluids through said bladder at a pressure sufficient to apply a compression force greater than ambient atmospheric pressure to the treatment region; a nonambient temperature fluid reservoir in selective fluid communication with said bladder; and a means for selecting between said nonambient temperature fluid reservoir and an ambient temperature fluid source as a feed for circulation of said treatment fluids through said bladder.
Claim 2
Independent Claim
87 words
An apparatus for treating bodily injuries or ailments comprising: a bladder applied to a treatment region of the body; a means for circulating treatment fluids through said bladder at a pressure sufficient to apply a compression force greater than ambient atmospheric pressure to the treatment region; a nonambient temperature fluid reservoir in selective fluid communication with said bladder; and a means for selecting between said nonambient temperature fluid reservoir and an ambient temperature fluid source as a feed for circulation of said treatment fluids through said bladder.
Claim 3
Dependent Claim
44 words
The apparatus of claim 1 wherein said bladder has a treatment fluid discharge port and a treatment fluid receiving port, each port provided with a closeable valve interrupting fluid communication between said feed and said bladder when said valve is in a closed position.
Claim 4
Dependent Claim
19 words
The apparatus of claim 1 further comprising means for securing said bladder around the treatment region of the body.
Claim 5
Dependent Claim
12 words
The apparatus of claim 1 wherein said circulation means comprises a pump.
Claim 6
Dependent Claim
29 words
The apparatus of claim 2 further comprising a flow restriction on a fluid line downstream of said discharge port sufficiently restrictive to create a fluid backpressure in said bladder.
Claim 7
Dependent Claim
36 words
The apparatus of claim 1 wherein said nonambient temperature reservoir contains a liquid at nonambient temperature as a first treatment fluid and said ambient temperature source contains air at ambient temperature as a second treatment fluid.
Claim 8
Dependent Claim
15 words
The apparatus of claim 6 wherein said liquid is water at a temperature above ambient.
Claim 9
Dependent Claim
15 words
The apparatus of claim 6 wherein said liquid is water at a temperature below ambient.
Claim 10
Dependent Claim
12 words
The apparatus of claim 1 further comprising a battery powering said pump.
Claim 11
Dependent Claim
19 words
The apparatus of claim 1 wherein said bladder is shaped to conform to the treatment region of the body.
Claim 12
Dependent Claim
15 words
The apparatus of claim 6 further comprising means for heating said liquid in said reservoir.
Claim 13
Dependent Claim
15 words
The apparatus of claim 6 further comprising means for cooling said liquid in said reservoir.
Claim 14
Independent Claim
192 words
An apparatus for treating bodily injuries or ailments comprising: a bladder having a receiving port for receiving treatment fluids into the interior of said bladder and a discharge port for discharging treatment fluids to the exterior of said bladder, said bladder applied to a treatment region of the body; a pump for circulating treatment fluids through said bladder at a pressure sufficient to apply a compression force substantially greater than ambient atmospheric pressure to the treatment region; a battery to power said pump; a nonambient temperature fluid reservoir in selective fluid communication with said bladder; a valve having two positions, said valve directing circulation of a first treatment fluid at a nonambient temperature from said reservoir through said bladder when in a first position and said valve directing circulation of a second treatment fluid at ambient temperature from an ambient temperature source through said bladder when in a second position; and a first closeable valve on said receiving port and a second closeable valve on said discharge port, said valves preventing fluid communication between the interior of said bladder and the exterior of said bladder when both are in a closed position.
Claim 15
Independent Claim
192 words
An apparatus for treating bodily injuries or ailments comprising: a bladder having a receiving port for receiving treatment fluids into the interior of said bladder and a discharge port for discharging treatment fluids to the exterior of said bladder, said bladder applied to a treatment region of the body; a pump for circulating treatment fluids through said bladder at a pressure sufficient to apply a compression force substantially greater than ambient atmospheric pressure to the treatment region; a battery to power said pump; a nonambient temperature fluid reservoir in selective fluid communication with said bladder; a valve having two positions, said valve directing circulation of a first treatment fluid at a nonambient temperature from said reservoir through said bladder when in a first position and said valve directing circulation of a second treatment fluid at ambient temperature from an ambient temperature source through said bladder when in a second position; and a first closeable valve on said receiving port and a second closeable valve on said discharge port, said valves preventing fluid communication between the interior of said bladder and the exterior of said bladder when both are in a closed position.
Claim 16
Dependent Claim
20 words
The apparatus of claim 13 wherein said pump, battery, and nonambient temperature fluid reservoir are contained within a portable unit.
Claim 17
Independent Claim
112 words
A method for treating a bodily injury or ailment comprising: applying a bladder to a treatment region of the body; circulating a nonambient temperature fluid through said bladder by means connected to said bladder from a nonambient temperature fluid reservoir in fluid communication with said bladder at a pressure sufficient to apply a compression force substantially greater than ambient atmospheric pressure to the treatment region; maintaining the temperature of said nonambient temperature fluid at a nonambient level; terminating circulation of said nonambient temperature fluid through said bladder; and displacing said nonambient temperature fluid from said bladder by feeding an ambient temperature fluid into said bladder while maintaining said compression force substantially constant.
Claim 18
Independent Claim
112 words
A method for treating a bodily injury or ailment comprising: applying a bladder to a treatment region of the body; circulating a nonambient temperature fluid through said bladder by means connected to said bladder from a nonambient temperature fluid reservoir in fluid communication with said bladder at a pressure sufficient to apply a compression force substantially greater than ambient atmospheric pressure to the treatment region; maintaining the temperature of said nonambient temperature fluid at a nonambient level; terminating circulation of said nonambient temperature fluid through said bladder; and displacing said nonambient temperature fluid from said bladder by feeding an ambient temperature fluid into said bladder while maintaining said compression force substantially constant.
Claim 19
Dependent Claim
33 words
The method of claim 15 further comprising sealing said bladder when said nonambient temperature fluid is completely displaced from said bladder by said ambient temperature fluid while maintaining said compression force substantially constant.
Claim 20
Dependent Claim
22 words
The method of claim 16 further comprising disconnecting said sealed bladder from said circulation means while maintaining said compression force substantially constant.
