Temperature controlled blankets and bedding assemblies

摘要

A temperature controlled blanket and a temperature controlled bedding system have provision of both recirculating temperature controlled fluid and temperature controlled gas to enhance performance for convectively heating or cooling a patient. Counter flow or co-flow heat exchanging principles between the temperature controlled liquid and the temperature controlled gas achieves temperature uniformity across different sections of the blanket and the bedding system. Drapes in the temperature controlled bedding system provide a gas envelope around a person using the bedding system. In a further embodiment of the bedding system, the air portion of the bedding system is provided for use with a patient bed which supplies the fluid portion of the overall bedding system. In a further embodiment of the bedding system, the fluid portion of the bedding system is provided for use with a patient bed which supplies the air portion of the overall bedding system.
