Abstract
Abstract A therapeutic method utilizing a therapeutic pad for heating or cooling which has a liquid absorbent to prevent liquid leakage in the event the sealed envelope of the pad is ruptured. The method of forming the pad includes vacuuming the thermoplastic envelope prior to sealing. The pad can be used alone or with a comforter to provide warmth or to remove heat from the body of the user.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
72 words
A method of applying therapy to the body of an animal comprising the steps of: (a) forming a microwavable pad having a liquid and a liquid absorbing means sealed within an envelope in which the absorbing means is compressed to at least 50% of its non-compressed size; (b) subjecting the pad to microwave radiation; and (c) placing the irradiated pad against the body of an animal to therapeutically heat the animal body.
Claim 2
Independent Claim
72 words
A method of applying therapy to the body of an animal comprising the steps of: (a) forming a microwavable pad having a liquid and a liquid absorbing means sealed within an envelope in which the absorbing means is compressed to at least 50% of its non-compressed size; (b) subjecting the pad to microwave radiation; and (c) placing the irradiated pad against the body of an animal to therapeutically heat the animal body.
Claim 3
Dependent Claim
26 words
The method of claim 1 wherein the step of subjecting the pad to microwave radiation comprises the step of placing the pad in a microwave oven.
Claim 4
Dependent Claim
26 words
The method of claim 1 wherein the step of subjecting the pad to microwave radiation comprises subjecting the pad to microwave radiation for approximately five minutes.
Claim 5
Dependent Claim
