ABSTRACT:
This invention relates to a portable heating and humidifying device which is effective in giving emergency therapy for accidental hypothermia. The device includes a charcoal fuel element heater (2;31) which is integrated-with a moisturized element (1;32), so that heated air from the heater (2;31) is humidified by being passed through the moisturized element (1;32). The moisturized element contains a body (11;38) of water absorbent material, such as fibre wadding or foamed polymer. The body (11;38) of water absorbent material is contained within a heat conducting first housing (10;41), so as to leave a first airspace (13;41) between substantial parts of the outer surface of the body (11;38) and the inner surface of the first housing (10;41). The first housing (10;42) is arranged within a heat insulating second housing (15;50) defining a second airspace (16;45) through which dry warm air is transported to the face of person breathing the humidified air.
