Filed:

May 11, 2005

Appl. No.:

11/127866

Inventors:

William Elkins - Lincoln CA, US
Kenneth L. Blanchard - Vacaville CA, US
Maurice Jordan - Antioch CA, US

Assignee:

bioCOOL technologies, LLC - McClellan CA

International Classification:

A41D 1/04
F28F 7/00

US Classification:

2458, 2102, 2 7, 165 46, 622593

Abstract:

A heat transfer fluid pathway is provided driven by a pump which feeds the heat transfer fluid through a vest and cap or other heat transfer garment, where the heat transfer fluid draws heat away from the body of the wearer. A drinkable heat sink material is located within a removable cartridge located within a heat exchange pouch. The heat transfer fluid passes from the heat transfer garment to the heat exchange pouch where heat drawn from the wearer is transferred to the heat sink material within the cartridge. A temperature control valve is provided along with a bypass line so that an adjustable amount of the heat transfer fluid is routed to the heat exchange pouch for temperature control. A supply of elevated pressure air is optionally provided to maintain optimal contact for efficient heat transfer within the heat exchange garment and the heat exchange pouch.

International Classification:

A41D 1/04

US Classification:

2458, 2102, 2 7, 607108

Abstract:

A garment is provided which is worn by a wearer and which actively cools the wearer. A heat transfer fluid pathway is provided which feeds the heat transfer fluid through a vest and cap or other heat transfer garment, where the heat transfer fluid draws heat away from the body of the wearer. The pathway is established between an inner layer proximate to the body of the wearer and an outer layer. Dots are provided which connect the inner layer and the outer layer together within the pathway. Fences are provided and borders to channel the heat transfer fluid along the pathway within the garment. A supply of elevated pressure air is optionally provided to maintain optimal contact for efficient heat transfer between the heat exchange fluid within the garment and the body of the wearer.

Assignee:

CoolSystems, Inc. - Berkeley CA

International Classification:

A61F007/00

US Classification:

607/108000

Abstract:

An embodiment of the present invention is a therapy component of an animate body heat exchanger that includes: (a) a bladder that contains a heat exchange medium, which bladder is compliant and is shaped to conform to a body part to be subjected to heat exchange; (b) a gas pressure bladder that overlays at least a portion of the bladder to direct gas pressure against the body part and against the portion to press the portion towards the body part, which gas pressure bladder is defined at least partially by a first pair of generally parallel walls; and (c) a plurality of first connections that connect the walls together interiorly of the gas pressure bladder to inhibit separation of the walls.
