Cooling compression sleeve
A cooling compression sleeve device generally including three layers, a flexible bottom layer, a flexible middle layer, and a flexible top layer, and two voids, the first void substantially filled with a cooling agent and the second void including a selectively inflatable air bladder, which in its preferred form is portable, cleanable, reusable, and useful to provide cooling therapy to the limbs of humans or animals and particularly to the knee, shoulder, and elbow joints.
1. A cooling compression sleeve device for providing therapy to limbs, said device comprising:
a flexible bottom layer comprising a first surface and a second surface opposite said first surface;
an interior first void facing said second surface and forming a closed container that is only filled with a liquid cooling agent, wherein said second surface is impermeable to said cooling agent and said cooling agent is in contact with said second surface;
a flexible middle layer comprising a third surface facing said first void and a fourth surface opposite said third surface, wherein said third surface is impermeable to said cooling agent, and wherein said fourth surface is impermeable to air;
an interior second void facing said fourth surface, wherein said second void comprises a selectively inflatable air bladder;
a flexible top layer comprising a fifth surface facing said second void and a sixth surface opposite said fifth surface, wherein said fifth surface is impermeable to air, wherein said sixth surface faces an outer environment; and
a valve coupled to said air bladder, wherein said valve is removably attachable to tubing, and wherein said tubing is coupled to a pump, wherein said valve comprises a valve base with a first aperture oriented orthogonally to the length of said valve base and a second aperture coupled to said first aperture and oriented coaxially to the valve base, wherein said valve base further comprises a tubular first member oriented coaxially to the length of said valve base and substantially aligned with said second aperture, wherein a tubular second member is coupled to said tubular first member, and wherein a tube insert is removably coupled to said tubular second member, wherein said tubular second member extends orthogonally with said tubular first member.
2. The device of claim 1 , wherein said bottom layer comprises a material with high thermal conductivity.
3. The device of claim 2 , wherein said first surface comprises a water absorbent material.
4. The device of claim 3 , wherein said water absorbent material comprises one or more of cotton, microfiber, and a cotton/microfiber mixture.
5. The device of claim 1 , wherein said second surface, said third surface, and said fourth surface each comprise at least one of flexible silicone or neoprene.
6. The device of claim 1 , wherein said first void comprises the entirety of the volume between said second surface of said bottom layer and said third surface of said middle layer.
7. The device of claim 1 , wherein said first void comprises one or more chambers divided by walls, wherein each wall connects said second surface to said third surface.
8. The device of claim 1 , wherein said cooling agent is reusable.
9. The device of claim 8 , wherein said cooling agent comprises at least one of a water-propylene glycol mixture or a water-antifreeze mixture.
10. The device of claim 1 , wherein said middle layer insulates said cooling agent from environmental or atmospheric heat external to said first void.
11. The device of claim 1 , wherein said sixth surface is adapted to resist abrasions and collisions and further adapted to resist punctures of said second void or said first void.
12. The device of claim 11 , wherein said top layer comprises nylon.
13. The device of claim 1 , further comprising tubing coupled at one end to the inflatable air bladder and inserted at another end through the second aperture and removably coupled to said first member, and further comprising tubing coupled at one end to said pump and removably coupled at another end to said tube insert.
14. The device of claim 13 , further comprising a plug member, wherein said plug member is securably insertable into said first aperture and adapted to restrict air flow in either direction through the tubing coupled to said inflatable air bladder and inserted through said second aperture.
15. The device of claim 1 , wherein said device comprises a detachable sleeve comprising a generally flat rectangular sheet, and wherein said sixth surface further comprises a fastener configured to fasten the relatively flat sheet of the device to itself to form an annular structure in the form of a sleeve or ring.
16. The device of claim 14 , wherein said plug member is movable within said first aperture from a first member position to a second member position, said plug member being configured to compress said tubing and restrict air flow through said tubing when in said first member position and to allow air flow through said tubing when in said second member position.
17. The device of claim 16 , wherein said plug member includes a plurality of threads configured to secure said plug member within said first aperture.
18. The device of claim 16 , wherein said plug member comprises an insertion portion insertable within said first aperture and a handle portion coupled to and extending orthogonally from said insertion portion.
