摘要：
A self-heating patch includes a bottom barrier layer, an air-activated heat-generating layer, an air regulation layer, optionally a top barrier layer, and optionally a skin contact layer, wherein the air-activated heat-generating layer is encapsulated by the air regulation layer and bottom barrier layer, and/or the top and bottom barrier layers, and the temperature of the patch, when the air-activated heat-generating layer has been exposed to air, and when the top barrier layer if present is removed, is controlled at least in part by the air regulation layer and a perimeter seal seals the air regulation layer to the bottom barrier layer around the perimeter of the patch. Optionally a temperature-responsive mechanism, such as a wax, can be used to reduce oxygen intake into the self-heating patch and thereby control the temperature of the self-heating patch during use. Optionally, a portion of the self-heating patch can be thermoformed.
