Abstract
Abstract A method of applying therapeutic heat a patient including forming a heating pad having an outer container having a first side formed by a material non-pervious to water and a second side formed by a material pervious to water. The container substantially encapsulates an outer bag containing and exothermic chemical and an inner bag containing a solvent. Further, the first side is covered by a layer of heat insulating materially and the second side by a layer of sponge-like material. The fist side and sponge-like material are contacted with water, thereby causing the sponge-like material to absorb water. Then the inner bag is fractured, causing the chemical and solvent to mix, producing heat, which is directed at the sponge-like material. The second side of the heating pad is then placed against the body, causing moist heat to be applied to the body. The pad may by tied to the body using straps extending from the ends of the container.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
234 words
A method of therapeutically heating a portion of an area of a body by applying moist heat comprising the steps of providing a moist heating pad having a flexible inner bag formed from a non-porous material and a flexible outer bag formed from a non-porous material; providing an exothermic chemical in said flexible outer bag and a solvent in said flexible inner bag; providing an outer flexible container having opposite ends, a first side formed of a material non-pervious to water and a second side formed from a material pervious to water, where the two sides together substantially encapsulate the flexible inner bag and the flexible outer bag; providing a flexible sheet of heat insulating material extending over the first side of said container; providing a water absorbent sheet made from a sponge-like material between the outer bag and the second side of the container; contacting the second side of the container and the absorbent sheet with water so that the absorbent sheet will absorb water; squeezing the flexible container to cause the inner bag to break and allow the exothermic chemical to mix with the solvent so as to produce heat that is directed toward the absorbent sheet to produce moist heat; and applying the flexible container, with the second side placed against said area of the body so that the moist heat will contact the skin in said area of the body.

A method of therapeutically heating a portion of an area of a body by applying moist heat comprising the steps of providing a moist heating pad having a flexible inner bag formed from a non-porous material and a flexible outer bag formed from a non-porous material; providing an exothermic chemical in said flexible outer bag and a solvent in said flexible inner bag; providing an outer flexible container having opposite ends, a first side formed of a material non-pervious to water and a second side formed from a material pervious to water, where the two sides together substantially encapsulate the flexible inner bag and the flexible outer bag; providing a flexible sheet of heat insulating material extending over the first side of said container; providing a water absorbent sheet made from a sponge-like material between the outer bag and the second side of the container; contacting the second side of the container and the absorbent sheet with water so that the absorbent sheet will absorb water; squeezing the flexible container to cause the inner bag to break and allow the exothermic chemical to mix with the solvent so as to produce heat that is directed toward the absorbent sheet to produce moist heat; and applying the flexible container, with the second side placed against said area of the body so that the moist heat will contact the skin in said area of the body.
Claim 3
Dependent Claim
36 words
The method of claim 1, including the steps of: providing a strap extending from each of said opposite ends of said outer container; and tying said moist heating pad to said the body using said straps.
Claim 4
Independent Claim
272 words
The method of dilating the capillary tubes in a heel of an infant child in preparation for extracting a blood sample therefrom comprising the steps of: providing a moist heating pad dimensioned to fit over the heel of the infant having a flexible outer bag formed from a non-porous material and a flexible inner bag formed from a non-porous material; providing an exothermic chemical in said flexible outer bag and a solvent in said flexible inner bag; providing an outer flexible container sized to extend over the heel of the infant and engage an ankle of the infant having opposite ends, a first side formed of a material non-pervious to water and a second side formed from a material pervious to water, where the two sides together substantially encapsulate the flexible inner bag and the flexible outer bag; providing a flexible sheet of heat insulating material extending over the first side of said container; providing a water absorbent sheet made from a sponge-like material over the second side of the container; contacting the second side of the container and the absorbent sheet with water so that the absorbent sheet will absorb water; squeezing the flexible container to cause the inner bag to break and allow the exothermic chemical to mix with the solvent so as to produce heat that is directed toward the absorbent sheet to produce moist heat; applying the flexible container, with the second side surface placed against the heel of the infant so that the moist heat will contact the skin of the heel of the infant; and securing the moist heating pad to the ankle of the infant.

Claim 6
Dependent Claim
40 words
The method of claim 3, including the steps of: providing a pair of straps, one each extending from each of said opposite ends of said outer container; and tying said moist heating pad to said the body using said straps.
