The heat patch of declare 1 additional comprising an adhesive on said reflective layer to safe the heat patch to the body. The warmth patch of claim 1 wherein stated warmth source features a heating composition that is able to producing warmth when a gas is equipped to said heating composition. The warmth patch of declare 1 wherein said heating composition generates warmth which maintains the heat patch in a spread of about 38 degrees centigrade to about forty four levels centigrade when the heat patch is exposed to the fuel. The warmth patch of declare 1 whereby the warmth source is a resistive heating component. The operations mentioned above with respect to the described strategies could also be carried out in a unique order from these described herein.
It must be famous that reflecting infrared energy might include reflecting infrared power having wavelengths in a range of about 3 to 50 microns, particularly having wavelengths near 10 microns. In addition, reflecting infrared vitality might embrace positioning a reflective layer 13 on the warmth patch 10 on, or close to, the portion 2 of the physique 1. In some pattern forms of the strategy, applying warmth to the portion 2 of the physique 1 consists of generating warmth within a heat patch 10 and applying the heat patch 10 to the portion 2 of the body 1.
It must be famous that attaching a warmth patch to a physique includes attaching the heat patch instantly, or indirectly, to the body. 1-three are representational and aren't necessarily drawn to scale. Certain proportions thereof could also be exaggerated, whereas others could also be minimized.
Any typical heating composition 46 could also be used to induce an exothermic reaction in the presence of a fuel corresponding to air. Some example heating compositions 46 embrace any mixture of iron powder, water, water-retaining agent, reaction promoter and salt. Another instance might embody fabricating the heat patch 40 utilizing a layering strategy in which a layer of heating composition forty six is deposited on the gasoline-permeable layer 42. The reflective layer 43 is then positioned on the heating composition 46 whereas the perimeter edges of the enclosure forty one are concurrently sealed to entrap the heating composition forty six.
Generating heat within the warmth patch 10 may embrace delivering current through a resistive factor or enabling an exothermic reaction within the warmth patch 10 (among other ways to generate warmth). In addition, generating heat throughout the warmth patch 10 could embrace controlling the warmth generated by the heat patch 10. The gas-permeable layer 42 could also be polyethylene or polypropylene non-woven material (amongst other materials).
The perimeter of the reflective layer 43 is bonded to the perimeter of the gasoline-permeable layer forty two by such means as adhesion, soften-bonding or stitching (amongst others). As an instance, one edge of the joined gasoline-permeable layer 42 and reflective layer forty three could also be left open, and after the heating composition forty six is inserted, the open edge is sealed to form the enclosure 41.
