Reflective heat patch
View Patent ↗A heat patch and method for providing therapy to a body. The heat patch includes a reflective layer and a heat source that is attached to the reflective layer. The reflective layer reflects infrared energy emitted by the body back into the body while the heat source applies heat to the body. The combination of supplying heat and reflecting infrared energy provides effective therapy to people with relatively deep tissue injuries. In another aspect, the heat patch includes an enclosure made from a gas-permeable layer and a reflective layer attached to the gas-permeable layer. A heating composition is sealed inside the enclosure to generate heat when a gas (e.g., air) is received through the gas-permeable layer. The heat generated by the heating composition is easily controlled such that heat patch can be maintained at a temperature well above ambient temperature.
1. A method of providing therapy to a body, the method comprising:
applying a heat patch to a portion of the body such that a reflective layer on the heat patch directly engages the body;
generating heat within the heat patch by delivering current through a resistive element; and
reflecting infrared energy emitted by the body back into the portion of the body using the reflective layer on the heat patch.
2. The method of claim 1 wherein generating heat within the heat patch includes controlling the heat generated by the heat patch.
3. The method of claim 1 wherein reflecting infrared energy includes reflecting infrared energy having wavelengths in a range of about 3 to 50 microns.
4. A method of providing therapy to a body, the method comprising:
enabling an exothermic reaction within a heat patch to generate heat, the heat patch including an enclosure formed of a gas-permeable layer and a reflective layer;
applying the heat patch to a portion of the body such that the reflective layer directly engages the body; and
reflecting infrared energy emitted by the body back into the portion of the body using the reflective layer on the heat patch.
5. The method of claim 4 wherein enabling an exothermic reaction within the heat patch includes exposing the heat patch to air.
6. The method of claim 4 wherein enabling an exothermic reaction within the heat patch to generate heat includes maintaining the heat patch at a temperature in a range of about 38 degrees centigrade to about 44 degrees centigrade.
