Heating and cooling blanket
First Claim
1. A cooling and heating blanket comprising:
- a. a blanket enclosure,b. heating means including a plurality of flexible elements positioned within said enclosure for being electrically energized for supplying heat to said enclosure, such that said enclosure may be retained above room temperature,c. cooling means including a plurality of flexible fluid carrying conduits positioned within said enclosure through which a heat transfer fluid can flow, such that said enclosure may be retained below room temperature,d. control means including an electric motor and a pump driven thereby located remotely relative to said enclosure,e. flexible conduit means connecting said enclosure and said cooling means,f. regulating means operatively associated with said heating means and said cooling means, said regulating means adapted to energize said control means or said heating means in response to increases and decreases of the temperature associated with said enclosure, such that the temperature of the blanket may be retained above or below the room temperature in which the blanket is located,g. said enclosure is divided into at least two major sections and each one of said sections may be independently regulated from said heating means or said cooling means,h. said major sections are each divided into respective zones,i. each one of said zones being independently controllable by said regulating means such that different respective portions of the human body may be concurrently maintained at temperatures ranging from below to above room temperature by said heating means and said cooling means, andj. said zones include;
(1) an upper zone for maintaining the upper torso of the body at a preselected temperature,(2) an intermediate zone for maintaining the lower torso at a preselected temperature, and(3) a lower zone for maintaining the legs at a preselected temperature.

Abstract
A cooling and heating blanket comprising a blanket enclosure with heating means including a plurality of flexible elements positioned within the enclosure for being electrically energized for supplying heat to the enclosure, such that the enclosure may be retained above room temperature, and cooling means including a plurality of flexible fluid carrying conduits positioned within the enclosure through which a heat transfer fluid can flow, such that the enclosure may be retained below room temperature. Control means including an electric motor and a pump driven thereby located remotely relative to the enclosure is provided with flexible conduit means connecting the enclosure and the cooling means, and regulating means is operatively associated with the heating means and the cooling means. The regulating means being adapted to energize the control means or the heating means in response to increases and decreases of the temperature associated with the enclosure, such that the temperature of the blanket may be retained above or below the room temperature in which the blanket is located.

11. A cooling and heating blanket comprising:
-
a. a blanket enclosure having at least upper and lower zones generally covering the torso and legs of the person using the blanket, b. heating means operatively associated with each of said zones, each of said heating means comprising a plurality of flexible elements positioned within said enclosure for being electrically energized for supplying heat to a respective zone of said enclosure, such that each one of said zones of said enclosure may be retained at relative temperatures, c. cooling means operatively associated with each of said zones, each of said cooling means comprising a plurality of flexible fluid carrying conduits positioned within each of said zones of said enclosure through which a heat transfer fluid can flow, such that each one of said zones of said enclosure may be retained at relative temperatures, d. control means operatively associated with each of said zones, each of said control means comprises an electric motor and a pump driven thereby located remotely relative to said enclosure, e. flexible conduit means connecting said enclosure and said cooling means, f. regulating means operatively associated with said heating means and said cooling means of each of said zones, each of said regulating means adapted to energize said control means or said heating means of a respective one of said zones in response to increases and decreases of the temperature associated with each one of said zones of said enclosure, so as to permit the temperature of said zones to be independently retained above or below predetermined temperature levels, such that the person using the blanket may obtain selective temperature levels for body comfort that may be concurrently maintained, g. fastening means within said enclosure for maintaining said flexible elements and said conduits in each of said zones in substantially fixed spaced relationship to each other, and h. said fastening means including; (1) a first resilient strap having alternate first sections engaging said conduits along one side thereof and first intermediate sections integrally formed with and between said alternate first sections for engagement with an oppositely disposed side of said flexible elements, and (2) a second resilient strap mounted in interlocking relationship to said first resilient strap by means of alternate second sections engaging said conduits along an oppositely disposed side as compared to said first sections, and second intermediate sections integrally formed with and between said second sections for engagement with an oppositely disposed side of said flexible elements as compared to said first intermediate sections. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
