Abstract

There is disclosed an article for use in cooling body temperature which comprises a garment having a coat and pant, with each having a body section adapted to receive a portion of the torso of the wearer and extensions from the body section to receive the wearer'"'"'s limbs. The garment includes a system for circulating temperature controlling fluid from a suitable source through patches removably received in pockets in each of body section and extensions.

Claims

1. An article for use in controlling body temperature, comprising:

a textile structure adapted to conform to the body surface and having a pocket with first and second openings in the edge thereof, and a casing extending from each opening, and

a system through which a temperature controlling fluid may be circulated, including

a patch disposable within the pocket and including side by side flow passages, a header at each end of the flow passages, an inlet to one header and an outlet from the other header, with the inlet and outlet being aligned, respectively, with the first and second pocket openings, and

a pair of flexible tubes each extending through a casing and a pocket opening and having one end fluidly connecting with a header of the patch, whereby upon connection of the other ends of the tubes with a source of temperature controlled fluid, such fluid may be circulated through the system, the patch being free to move within its pocket and the tubes being free to move within their casings so that the system is freely moveable independently of the textile structure.

2. As in claim 1, wherein:

the textile structure is sufficiently flexible to fold about a substantial portion of a body limb.

3. As in claim 2, wherein:

the textile structure is formed of a stretchable fabric.

4. As in claim 1, wherein:

the patch comprises a pair of films sealed to one another along their edges and along spaced paths to form the flow passages between the headers.

5. As in claim 1, wherein:

the pocket and casings are sewn on one side of the textile structure.

6. As in claim 1, wherein

the textile structure also has a second pocket with first and second openings in the edge thereof and a casing extending from each opening, and the system also includes a second patch disposable within the second pocket, a header at each end of the flow passages, an inlet to one header and an outlet from the other header, with the inlet and outlet being aligned, respectively, with the first and second pocket openings, and

a pair of flexible tubes each extending through a casing and a pocket opening having one end fluidly connecting with a header of the second patch with the inlet and outlet being aligned, respectively, with the first and second pocket openings, the outlet of one being connected with the inlet of the other patch, so that there is series flow from one to the other.

7. As in claim 6, wherein:

the portion of the structure intermediate the pockets is flexible to permit the patches to be disposed over both ends of an articulated limb.

8. As in claim 1, wherein:

there are two or more patches removably disposable within a single pocket.

9. As in claim 1, wherein:

the patch has one inlet and multiple outlets.

10. As in claim 1, wherein:

the patch has one outlet and multiple inlets.

11. As in claim 1, wherein:

the patch includes a pair of patch end sections joined by a reduced mid section which is sufficiently flexible to permit the patch sections to be disposed over opposite sides of a limb,

one patch section having a pair of outlet headers and the other patch section having a pair of inlet headers with the outlet headers fluidly connecting with the inlet headers within the mid section, and

the flow passages of the patch sections extend parallel to one another.

12. An article for use in controlling body temperature, comprising:

a garment having a body section adapted to receive a portion of the torso of the wearer and extensions from the body section to receive the wearer'"'"'s limbs,

each of the body section and extensions having a pocket with first and second openings in the edge thereof, and

casings each extending between the openings in the pockets of alternate patches, and

a system through which a temperature controlling fluid may be circulated, including

a patch disposable within each pocket and including side by side flow passages, a header at each end of the flow passages, an inlet to one header and an outlet from the other header, with the inlet and outlet being aligned, respectively, with the first and second pocket openings, and

a pair of flexible tubes each extending through a casing and a pocket opening and having one end fluidly connecting with a header of the patch, whereby, upon connection of the other ends of the tubes with a source of temperature controlled fluid, such fluid may be circulated through the system, the patches being free to move within their pockets and the tubes being free to move within their casings so that the system is freely moveable independently of the garment.

13. As in claim 12, wherein:

each extension of the garment is sufficiently flexible to fold about a substantial portion of a body limb.

14. As in claim 12 wherein:

the garment is formed of a stretchable fabric.

15. As in claim 14, wherein:

each patch comprises a pair of films sealed to one another along their edges and along spaced paths to form the flow passages therebetween.

16. As in claim 12, wherein:

the pocket and casings are sewn on the front and back of the body section and along the extensions of the garment.

17. As in claim 12, wherein

each of the garment extensions also has a second pocket with first and second openings in the edge thereof and a casing extending from each opening, and the system also includes a patch disposed within each second pocket, a header at each end of the flow passages thereof, an inlet to one header and an outlet from the other header, with the inlet and outlet being aligned, respectively, with the first and second pocket openings, and

a pair of flexible tubes each extending through a casing and a pocket opening having one end fluidly connecting with a header of the second patch, the other ends of one tube of each patch connecting with one another so that there is series flow through the extension patches.

18. As in claim 17, wherein:

the portion of each extension intermediate the pockets thereof is flexible to permit the patches to be disposed over opposite sides of an articulated limb.

19. As in claim 12, wherein:

the garment is a coat in which the extensions are sleeves.

20. As in claim 12, wherein:

the garment is a pant in which the extensions are legs.

22. As in claim 12, wherein

there are two or more patches removably disposable within a single pocket.

23. As in claim 12, wherein

the patch has one inlet and multiple outlets.

24. As in claim 12, wherein

the patch has one outlet and multiple inlets.

25. As in claim 12, wherein

the patch includes a pair of patch end sections joined by a reduced mid section which is sufficiently flexible to permit the patch sections to be disposed over opposite sides of a limb,

one patch section having a pair of outlet headers and the other patch section having a pair of inlet headers within the mid section, and

the flow passages of the patch sections extend parallel to one another.

21. An article for use in controlling body temperature, comprising:

a garment including a pant and coat,

each of the coat and pant comprising a body section adapted to surround upper and lower portions of the torso of the wearer, and extensions from each comprising arms of the coat and legs of the pant, each of the body section and extensions having a pocket with first and second openings in the edge thereof, and

casings extending between the openings in the alternate pockets of each of the body section and extensions of each garment,

a system through which a temperature controlling fluid may be circulated, including

a patch disposable within each pocket and including side by side flow passages, a header at each end of the flow passages, an inlet to one header, an outlet from the other header, with the inlet and outlet being aligned, respectively, with the first and second pocket openings, and

a pair of flexible tubes each extending through a casing and a pocket opening and having one end fluidly connected with the inlet or outlet of the patch aligned with the opening, and

the tubes extending from the inlet of one patch and the outlet of another patch of the pant being connected to the outlet and the inlet of another patch, respectively, of the coat, whereby

upon connection to tubes extending from the inlet of one patch and the outlet of another patch of the garment with a source thereof, temperature controlled fluid may be circulated through the system, the patches being free to move within its pocket and the tubes being free to move within their casings so that the system is freely moveable independently of the textile structure.
