Abstract

Embodiments of a fluid absorption and distribution enhancement (FADE) product comprises at least one flow media layer, and at least one superabsorbent polymer layer.

Claims (28)

1. A fluid absorption and distribution enhancement (FADE) product comprising:

at least two flow media layers; and

at least one superabsorbent polymer layer sandwiched between the flow media layers.

2. The FADE product of claim 1 wherein the flow media layers comprise woven material, non-woven material, pressed mesh, knitted mesh, scrim material, or combinations thereof.

3. The FADE product of claim 1 wherein the flow media layers comprise of nylon, polypropylene, propylene ethylene copolymer, polyolefin, polyester, polyamide, polyvinyl chloride, polyurethane, or combinations thereof.

4. The FADE product of claim 1 further comprising superabsorbent fiber material.

5. The FADE product of claim 1 further comprising one or more flow channels in the superabsorbent polymer layer.

6. The FADE product of claim 1 wherein the superabsorbent polymer layer comprises poly (sodium acrylate) homopolymer or copolymer, polyacrylamide copolymer, ethylene maleic anhydride copolymer, polyvinyl alcohol copolymers, polyethylene oxide, polyacrylonitrile copolymer, cross-linked carboxymethylcellulose, or combinations thereof.

7. The FADE product of claim 1 further comprising at least two flow media layers in contact with one another.

8. The FADE product of claim 1 further comprising deionizing material or a deionizing coating.

9. The FADE product of claim 1 wherein the superabsorbent polymer layer comprises small slits configured to facilitate stretching.

10. The FADE product of claim 1 wherein the superabsorbent polymer layer comprises superabsorbent polymer impregnated into a stretchable fabric layer.

11. A stretcher comprising a body support frame and the fluid absorption and distribution enhancement product of claim 1 .

12. The stretcher of claim 11 further comprising a mattress disposed over the fluid absorption and distribution enhancement product, the mattress comprising a plurality of drainage holes configured to allow bodily fluid flow through the drainage holes and into the fluid absorption and distribution enhancement product.

13. A method of enhancing fluid absorption and distribution enhancement under load comprising:

providing a fluid absorption and distribution enhancement product under an applied load, wherein the fluid absorption and distribution enhancement product comprises at least two flow media layers, and at least one superabsorbent polymer layer comprising one or more flow channels extending therethrough, wherein the two flow media layers comprise an upper flow media layer and a lower flow media layer, and wherein the superabsorbent polymer layer is disposed between the upper flow media layer and lower flow media layer; and

enhancing fluid distribution and fluid absorption in the superabsorbent polymer layer by draining fluid laterally by the upper flow media layer and through flow channels in the superabsorbent layer to the lower flow media layer.

14. The method of claim 13 wherein the superabsorbent polymer layer comprises poly (sodium acrylate) homopolymers or copolymers, polyacrylamide copolymers, ethylene maleic anhydride copolymers, polyvinyl alcohol copolymers, polyethylene oxides, polyacrylonitrile copolymers, cross-linked carboxymethylcellulose, or combinations thereof.

15. A fluid absorption and distribution enhancement (FADE) product comprising:

at least three flow media layers including an upper flow media layer, a middle flow media layer, and a lower flow media layer; and

at least two superabsorbent polymer layers comprising a first superabsorbent polymer layer disposed between the upper flow media layer and the middle flow media layer, and a second superabsorbent layer disposed between the middle flow media layer and the lower flow media layer.

16. The FADE product of claim 15 wherein the flow media layers comprise woven material, non-woven material, pressed mesh, knitted mesh, scrim material, or combinations thereof.

17. The FADE product of claim 15 wherein the flow media layers comprise of nylon, polypropylene, propylene ethylene copolymer, polyolefin, polyester, polyamide, polyvinyl chloride, polyurethane, or combinations thereof.

18. The FADE product of claim 15 further comprising one or more flow channels in the superabsorbent polymer layer.

19. The FADE product of claim 17 wherein the superabsorbent polymer layer comprises poly (sodium acrylate) homopolymer or copolymer, polyacrylamide copolymer, ethylene maleic anhydride copolymer, polyvinyl alcohol copolymers, polyethylene oxide, polyacrylonitrile copolymer, cross-linked carboxymethylcellulose, or combinations thereof.

20. A fluid absorption and distribution enhancement (FADE) product comprising:

at least one flow media layer; and

at least one superabsorbent polymer layer disposed above or below the flow media layer and comprising at least one flow channel.
