Improvements in heat exchanging head pieces for cooling or heating the entire hair bearing (scalp) area of the human head; improvements in a blank form for such product and purposes for filling with heat exchanging materials; a heat exchanging head piece for cancer chemotherapy patients to cool the scalp to prevent hair loss during chemotherapy injections; devices and processes for heat exchanging the human scalp including variable headband constriction and limitedly variable whole upper skull compression for full, holiday free cooling or heating.

Heat transfer devices for the scalp

This invention relates to a method of producing articles which generate heat at a substantially constant temperature for an extended period of time and which are able to remain in a stable state until such time as the generation of heat is desired. The method also relates to supercooled fluids produced by such methods. The method involves the processing of supercooled fluids such as hypo to produce this stable state. As a first step, a suitable material such as ethylene glycol may be added to the supercooled fluid to stabilize the supercooled fluid and to decrease the generation of heat in the supercooled fluid to obtain a desired temperature. The mixture is then heated to a relatively high temperature considerably above the melting temperature of the supercooled fluid. With the mixture at the high temperature, water is added to provide a particular specific gravity and an alkali is added to provide a particular pH. The mixture may then be poured into rupturable pouches while being maintained at the high temperature. The mixture in the pouches is then allowed to cool slowly to ambient temperatures and is placed in a separate container with a triggering material.
