Abstract
A thermal treatment apparatus is built around an enclosure having pairs of separate compartments with each pair separated by a portal gate. The enclosure has a means for securing it in intimate contact with a skin surface. A chemically activatable substance is enclosed within one or more of the compartments and an activator is enclosed under pressure within one or more further compartments. A thermal sensor is positioned in contact, or near contact, with the skin surface, and a means for opening the portal gate, in accordance with a set point temperature and the actual temperature of the skin surface, is provided. Upon opening the portal gate, the activator is driven into contact with the chemically activatable substance thereby producing a chemical reaction causing a thermal exchange between the enclosure and the skin surface so as to cool or heat it.
