Localized heat transfer device

摘要

The invention provides systems for topically heating or cooling an animal or human body, and more particularly concerns a modular system in which a heating or cooling liquid is circulated in a hermetically sealed flow path between a heating or cooling device and a heating or cooling pad. In a preferred embodiment, the flow path includes a cassette which is reversibly engageable with a pump and a heating or cooling unit located in a housing.
