Abstract

A patient support includes a bladder layer with a plurality of bladders, a pneumatic supply system, and a plurality of tubes in fluid communication with pneumatic supply system. The tubes are coupled to and guided by the bladder layer so that the tubes and bladder layer may remain in close registry when being handled, for example, either during the assembly process or cleaning process.

First claim

We claim:

1. A patient support, comprising:
a bladder layer with a plurality of bladders;
a pneumatic supply system; and
a plurality of tubes in fluid communication with the pneumatic supply system and the bladder layer, the tubes coupled to and guided by a lower sheet forming the bladders of the bladder layer, the bladder layer including a harness for harnessing and holding the tubes, wherein the harness comprises a flange with a plurality of openings there through to thereby hold the tubes in the flange, wherein the bladder layer comprises an upper sheet, and the flange comprises a portion of the lower sheet.

2. The support of claim 1 , wherein the tubes comprise supply tubes.

3. The support of claim 1 , wherein the tubes comprise sensing tubes.

4. The support of claim 1 , wherein the tubes comprise sensing tubes and supply tubes.

5. The support of claim 1 , wherein the bladder layer includes a plurality of supports, the supports comprising channels.

6. The support of claim 5 , wherein the supports are formed from patches of sheet material attached at or to the lower sheet of the bladder layer.

7. The support of claim 1 , wherein the bladder layer includes at least two zones, with each zone being configured to be separately inflatable.

8. The support of claim 1 , wherein the openings comprise slits.

9. The support of claim 1 , wherein the bladder layer includes an array of bladders and a plurality of transverse openings allowing air to pass through the bladder layer to direct air flow through the bladder layer.

10. The support of claim 1 , wherein each of said bladders has a hexagonal cross-section.

11. The patient support according to claim 1 , further comprising:
a foam crib having first and second sections, said foam crib supporting said bladder layer; and
a gel cushioning layer forming a cushion surface for a patient and having a plurality of gel walls configured to buckle under the weight of a patient, said gel cushioning layer supported on the foam crib and joined to the two sections of the foam crib, and the gel-cushioning layer forming a hinge for the two sections of the foam crib.

12. The support of claim 11 , wherein the first section comprises a head/body end and the second section comprises a foot end, the gel cushioning layer forming a hinge between the foot end and the head/body end, and the head/body end supporting said bladder layer.

13. The support of claim 12 , wherein the foot end is releasably coupled to the head/body end.

14. The support of claim 13 , wherein the foot end is releasably coupled to the head/body end by hook and loop strips.

15. The support of claim 12 , wherein the foot end is releasably coupled to the head/body end by a joint, the joint forming line management channels.

16. A patient support comprising:
a bladder layer with a plurality of bladders;
a pneumatic supply system; and
a plurality of tubes in fluid communication with the pneumatic supply system and the bladder layer, the bladder layer including a sheet forming the bladders, the sheet including a harness holding and harnessing the tubes, and the harness including a flange with a plurality of openings there through to thereby hold the tubes in the harness, wherein the sheet comprises a lower sheet joined with an upper sheet, and the flange being formed by a portion of the lower sheet.

17. The support of claim 16 , wherein the openings comprise slits.

18. The patient support of claim 16 , further comprising:
a blower unit having an output;
a foam crib supporting the bladder layer, the foam crib having recesses formed therein to form channels and in fluid communication with the output of the blower; and
a cover extending over the recesses to cover the recesses, the cover having openings for directing air flow from the channels to the underside of the bladder layer.

19. The support of claim 18 , wherein said bladder layer has a plurality of openings therethrough to allow air flow from the channels to pass through the bladder layer.

20. The support of claim 18 , wherein the cover is adapted to seal against the underside of the bladder layer to reduce air loss between the bladder layer and the channels.

21. The support of claim 20 , wherein the cover supports a resilient pad, the pad including openings aligning with the openings of the cover.
