20170119574 · 2017-05-04 · ·

In accordance with one embodiment of the present invention, the invention comprises a pliable enclosure containing a Phase Change Material (PCM) that maintains a nearly constant predetermined temperature while transmitting heat during phase change. The predetermined temperature is maintained which the PCM absorbs heat from the body of the patient, thus maintain the patient's body temperature at a nearly constant predetermined temperature for as long as the PCM material is transitioning phase. The pliable enclosure, which in an embodiment forms an enclosed volume, may be comprised of a shell which contains the PCM. The shell may be fabricated from polyethylene, polyurethane, or any other pliable material and may further comprise graphene covering on at least one of its surfaces to provide a tough exterior that is resistant to puncture by, for example, hypodermic needles, suture needles, scalpels, or other sharp instruments.

Phase change heat packs

A heat pack includes a housing, a first phase change material (PCM) that is contained in the housing, and a thermal storage buffer that is contained in the housing. The thermal storage buffer includes a second PCM. An initiator is in operative contact with the first PCM. Activation of the initiator causes crystallization of the first PCM, and the first PCM cooperates with the thermal storage buffer to provide heat at a predetermined temperature range upon crystallization of the first PCM.
