Reinforced therapeutic wrap and method
View Patent ↗A therapy wrap for treatment of at least a portion of an animate body having improved kink resistance. The therapy wrap may be selectively reinforced for improved kink resistance in only a portion of the wrap. The reinforcement may decrease the kink radius. The wrap may include a kink reducer in all or only a selected kink-prone region. The kink reducer may be selectively configured attachment points or spot welds. The therapy wrap may include a reinforcement layer of one or more discrete reinforcement members. The wrap may be formed by pre-tensioning the material layers while forming the fluid bladder and/or gas pressure bladder. The therapy wrap may be adapted to compensate for conditions that normally cause kinking of the wrap or buckling of the fluidic channels. Also disclosed are methods of manufacturing the wrap and methods of administering a temperature-controlled treatment to an anatomical body part.
1. A therapy wrap for providing heating or cooling to an anatomical body part, the wrap comprising:
a flexible fluid bladder for containing a heat exchange medium, the fluid bladder including an inlet, an outlet, and a fluid flowpath connecting the inlet and the outlet;
a gas pressure bladder overlaying the fluid bladder for applying a compressive force to a portion of the fluid bladder in contact with the body part; and
a reinforcement member disposed within the gas pressure bladder at one or more kink prone regions of the gas pressure bladder, wherein the reinforcement member reduces kinking at the one or more kink prone regions of the gas pressure bladder.
2. The therapy wrap of claim 1 , wherein the reinforcement member is a made from a porous material.
3. The therapy wrap of claim 2 , wherein the porous material has an open cell foam structure that is gas permeable.
4. The therapy wrap of claim 1 , wherein the reinforcement member has a hole and a weld that passes through the hole that secures the reinforcement member within the gas pressure bladder.
5. The therapy wrap of claim 4 , wherein the reinforcement member is donut shaped.
6. The therapy wrap of claim 1 , wherein the reinforcement member is secured to the gas pressure bladder with an adhesive.
7. The therapy wrap of claim 1 , further comprising a plurality of attachment points connecting walls of the bladder and defining a plurality of fluidic channels in the flow path.
8. The therapy wrap of claim 7 , wherein the reinforcement member is secured within the gas pressure bladder with a weld that is aligned with one of the attachment points.
9. The therapy wrap of claim 7 , wherein the size and shape of the reinforcement member is defined at least in part by one or more of the plurality of attachment points within the bladder.
10. The therapy wrap of claim 1 , wherein the reinforcement member is curvilinear.
11. The therapy wrap of claim 10 , wherein the reinforcement member is circular or oval.
12. The therapy wrap of claim 1 , wherein the reinforcement member is rectilinear.
13. The therapy wrap of claim 12 , wherein the reinforcement member is square or rectangular.
14. The therapy wrap of claim 1 , wherein the size and shape of the reinforcement member is defined at least in part by a perimeter of the gas pressure bladder.
15. The therapy wrap of claim 1 , wherein the size and shape of the reinforcement member is defined at least in part by one or more interior fences disposed within the fluid bladder or gas pressure bladder.
16. The therapy wrap of claim 1 , wherein the reinforcement member is made from an insulating material.
17. The therapy wrap of claim 16 , wherein reinforcement member is adhered to a wall of the gas pressure bladder that is adjacent or shared with the fluid bladder.
18. A therapy wrap for providing treatment to an anatomical body part, the wrap comprising:
a gas pressure bladder for applying a compressive force to the body part; and
a reinforcement member disposed within the gas pressure bladder at one or more kink prone regions of the gas pressure bladder, wherein the reinforcement member reduces kinking at the one or more kink prone regions of the gas pressure bladder, wherein the reinforcement member has a hole and a weld that passes through the hole that secures the reinforcement member within the gas pressure bladder.
19. The therapy wrap of claim 18 , wherein the reinforcement member is a made from a porous material.
20. The therapy wrap of claim 19 , wherein the porous material has an open cell foam structure that is gas permeable.
21. The therapy wrap of claim 18 , wherein the reinforcement member is donut shaped.
22. The therapy wrap of claim 18 , wherein the reinforcement member is curvilinear.
23. The therapy wrap of claim 22 , wherein the reinforcement member is circular or oval.
24. The therapy wrap of claim 18 , wherein the reinforcement member is rectilinear.
25. The therapy wrap of claim 24 , wherein the reinforcement member is square or rectangular.
26. The therapy wrap of claim 18 , wherein the size and shape of the reinforcement member is defined at least in part by a perimeter of the gas pressure bladder.
27. The therapy wrap of claim 18 , wherein the size and shape of the reinforcement member is defined at least in part by one or more interior attachment features disposed within the gas pressure bladder.
28. A therapy wrap for providing treatment to an anatomical body part, the wrap comprising:
a gas pressure bladder for applying a compressive force to the body part; and
a reinforcement member disposed within the gas pressure bladder at one or more kink prone regions of the gas pressure bladder, wherein the reinforcement member reduces kinking at the one or more kink prone regions of the gas pressure bladder, wherein the reinforcement member is secured to the gas pressure bladder with an adhesive.
29. A therapy wrap for providing treatment to an anatomical body part, the wrap comprising:
a gas pressure bladder for applying a compressive force to the body part; and
a reinforcement member disposed within the gas pressure bladder at one or more kink prone regions of the gas pressure bladder, wherein the reinforcement member reduces kinking at the one or more kink prone regions of the gas pressure bladder, wherein the reinforcement member is secured within the gas pressure bladder with one or more welds.
