Abstract
Abstract Heat-controlled exchange pouches for strapping to strategic areas of a patient''s body where the main blood arteries are close to the skin surface. Each pouch is a flat, flexible tubing array within a removable bag, conformable to the body area which the pouch contacts. Separate fluid supply and return tubes for the pouches at each side of the body provide independent temperature control.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
78 words
A pouch system for temperature control of a person''s body comprising a plurality of individual pouches, each pouch comprising a plurality of flexible tubes, a removable bag covering the plurality of tubes, the tubes having inlet ends adjacent one another and outlet ends adjacent one another, an inlet manifold connected to the inlet ends, an outlet manifold connected to the outlet ends, and supply tubes for conveying temperature-controlled fluids through the plurality of tubes of all the pouches.
Claim 2
Dependent Claim
78 words
A pouch system for temperature control of a person''s body comprising a plurality of individual pouches, each pouch comprising a plurality of flexible tubes, a removable bag covering the plurality of tubes, the tubes having inlet ends adjacent one another and outlet ends adjacent one another, an inlet manifold connected to the inlet ends, an outlet manifold connected to the outlet ends, and supply tubes for conveying temperature-controlled fluids through the plurality of tubes of all the pouches.
Claim 3
Dependent Claim
31 words
The pouch system of claim 1 including elastic strap means connected to the bags for attaching the pouches to the person''s body and maintaining them in constant compression against the skin.
Claim 4
Dependent Claim
44 words
The pouch system of claim 1 wherein the supply tubes comprise single tubes interconnecting the manifolds of the pouches for serial distribution of the temperature-controlled fluids through the pouches, the supply tubes being of larger diameter than individual ones of the plurality of tubes.
Claim 5
Dependent Claim
52 words
The pouch system of claim 3 wherein the pouches are adapted for attachment to the neck, the upper right arm, the upper right thigh, the upper left arm, and the upper left thigh of the person''s body, the neck pouch comprising two independent pluralities of tubes each having inlet and outlet manifolds.
Claim 6
Dependent Claim
48 words
The pouch system of claim 4 including separate supply tubes for independent serial circulation of temperature-controlled fluid through the neck, upper right arm, and upper right thigh pouches, and separate supply tubes for circulation of temperature-controlled fluid through the neck, upper left arm, and upper left thigh pouches.
Claim 7
Dependent Claim
42 words
The pouch system of claim 5 wherein the supply tubes for the right side pouches are independent of the supply tube for the left side pouches, the right side and left side supply tubes being connectible to independent temperature-controlled fluid circulatory machines.
Claim 8
Dependent Claim
41 words
The pouch system of claim 4 wherein the independent pluralities of tubes in the neck pouch are of U-shape configurations with the base of the U of one tube plurality adjacent the base of the U of the other tube pluraLity.
Claim 9
Dependent Claim
30 words
The pouch system of claim 4 wherein the independent pluralities of tubes in the neck pouch are straight and the two pluralities of tubes are positioned laterally adjacent one another.
Claim 10
Dependent Claim
22 words
The pouch system of claim 1 wherein at least one side of each bag is closeable with a hook and pile fastener.
Claim 11
Dependent Claim
33 words
The pouch system of claim 3 wherein the supply tubes are adapted for reversible connection to a temperature-controlled fluid circulation machine for reversing the direction of serial flow of fluid through the pouches.
