Portable thermoelectric cooling device for hypothermia therapy of the skull

摘要

A device for cranial hypothermia that provides controlled cooling (heating) through a helmet and collar. The helmet and collar have a plurality of distributed thermoelectric coolers (TECs) dispersed in the helmet structure, and a liquid refrigerant system for exchanging heat outside the helmet and collar to keep the TEC running effectively Including. The control circuit drives the TEC in response to measurements from a plurality of temperature sensors held adjacent to the patient wearing the helmet and collar. In at least one embodiment, the TECs are grouped within interconnected flexible modules that each include an internal cooling passage adjacent to the TEC.
