Therapy component of an animate body heat exchanger and method of manufacturing such component

A therapy component of an animate body heat exchanger comprising, in combination:

• A. a bladder configured to direct the flow of a heat exchange liquid therethrough, which bladder is compliant and is shaped to conform to a body part to be subjected to heat exchange;
• B. a gas pressure bladder overlaying the heat exchange liquid bladder to direct gas pressure against said body part and against said heat exchange liquid bladder to press the same toward said body part, which gas pressure bladder is defined by a first pair of generally parallel walls and said heat exchange liquid bladder is defined by a second pair of generally parallel walls;
• C. a plurality of first connections connecting said first pair of walls together interiorly of said gas pressure bladder to inhibit the separation of said walls;
• and
• D. a plurality of second connections interiorly of said heat exchange liquid bladder to aid in directing desired flow of said heat exchange liquid through the same.

In a method of manufacturing a therapy component of an animate body heat exchanger, the combination of steps comprising:

• A. securing a pair of generally liquid tight and compliant walls together to form a bladder for containing a heat exchange medium, which bladder is shaped to conform to a body part to be subjected to heat exchange;
• B. securing a pair of compliant walls together to form a gas pressure bladder to overlap at least a portion of the heat exchange medium bladder;
• and
• C. forming a plurality of first connections between said pair of walls which form said gas pressure bladder, interiorly of said gas pressure bladder to inhibit the separation of said walls.
