Uterine heat patch

A method of manufacturing a heat patch, the method comprising:

• laminating a first polyethylene (PE) film layer to a non-woven topsheet;
• disposing a heat-generating component adjacent to the first PE film layer on a side of the first PE film layer opposite the non-woven topsheet, the heat-generating component comprising an iron-based composition;
• joining a non-woven backing layer to the heat-generating component, the non-woven backing layer comprising an adhesive configured for attaching the heat patch to an inside surface of an article of clothing, the adhesive being positioned on a side of the non-woven backing layer opposite the heat-generating component;
• and
• cutting the laminated structure to define a contoured shape configured to fit an abdominal region.

A method for heat therapy, the method comprising:

• providing heat therapy via a heat-generating component within a heat patch, the heat-generating component comprising an iron-based exothermic formulation, the heat patch comprising:
• a non-woven topsheet forming a skin-facing surface, the topsheet being breathable;
• a first polyethylene (PE) film layer positioned between the non-woven topsheet and the heat-generating component;
• a non-woven backing layer comprising an adhesive layer for attaching the heat patch to the inside of clothing;
• and
• a release layer covering the adhesive prior to application.
