  • Patent number: 8945072
    Abstract: A heat generating device includes a holder and a heat generating member that is enclosed in the holder and that contains an oxidizable metal, a reaction accelerator, an electrolyte, and water. The heat generating member contains a transdermally-absorbable medicament and a solvent for dissolving the transdermally-absorbable medicament. It is preferable that the solvent is at least one type of polyol selected from polyols that are in their liquid state at 25° C. It is also preferable that the heat generating member further contains at least one type of solvent composed of an oily agent that is in its liquid state at 25° C. It is also preferable that the heat generating member further contains a surfactant. It is also preferable that the polyol is polyethylene glycol.
