Abstract

A localized patient support comprises a base, an annular ring supported above the base and defining a cavity, and a gel pad having a plurality of sections located in the cavity. In some embodiments, the localized patient support includes a plurality of inflatable bladders located in the cavity between the base and the gel pad. At least some of the sections of the gel pad are vertically movable substantially independently of adjacent sections of the gel pad due to inflation or deflation of at least one of a corresponding bladder of the plurality of inflatable bladders. In some embodiments, the base and the annular ring comprise foam elements. In some embodiments, a cover is provided and has a stretchable anti-shear portion over situated above the gel pad.

Claims

1. A localized patient support comprising:

a base,

an annular ring supported above the base and defining a cavity,

a gel pad having a plurality of sections located in the cavity, at least some of the sections of the gel pad located in the cavity being vertically movable substantially independently of adjacent sections of the gel pad, and

a plurality of bladders located between the base and the gel pad, the plurality of bladders being inflatable and deflatable to change the elevation of the plurality of sections of the gel pad relative to the base, wherein spaces are defined between confronting walls of the sections of the gel pad and wherein each section of the gel pad overlies at least two respective bladders of the plurality of bladders without any bladder of the plurality of bladders being situated directly underneath more than one of the sections of the gel pad.

2. The localized patient support of claim 1, further comprising at least one sensor associated with each section of the gel pad located in the cavity.

3. The localized patient support of claim 2, further comprising at least two sensors located above each section of the gel pad located in the cavity.

4. The localized patient support of claim 2, wherein each sensor of the at least one sensor measures one or more of the following parameters:

pressure, temperature, humidity, and air circulation.

5. The localized patient support of claim 1, wherein the base comprises a foam pad and the annular ring comprises a foam ring.

6. The localized patient support of claim 1, wherein and the gel pad further comprises an annular section overlying the annular ring.

7. The localized patient support of claim 6, further comprising at least one sensor coupled to each section of the gel pad located in the cavity and a plurality of sensors coupled to the annular section of the gel pad overlying the annular ring.

8. The localized patient support of claim 1, further comprising a disposable cover having a stretchable anti-shear portion configured to substantially cover a top surface of the annular ring and top surfaces of the sections of the gel pad located in the cavity.

9. The localized patient support of claim 8, further comprising a foam pad supported above the stretchable anti-shear portion of the cover.

10. The localized patient support of claim 1, further comprising a pressure regulator coupled to the plurality of bladders, a plurality of pressure sensors located above the plurality of bladders, and a processor coupled to the plurality of sensors and coupled to the pressure regulator.

11. The localized patient support of claim 10, wherein the plurality of sensors are coupled to the gel pad.

12. The localized patient support of claim 1, wherein the base, the annular ring, and the gel pad are together sized and configured to support only a portion of one of a patient'"'"'s chest region and the patient'"'"'s pelvic region.

13. The localized patient support of claim 1, wherein the base comprises a first foam pad and a second foam pad.

14. The localized patient support of claim 1, wherein the gel pad further comprises a plurality of web portions interconnecting adjacent sections of the gel pad.

15. The localized patient support of claim 1, wherein the plurality of sections of the gel pad comprise a central section and a plurality of peripheral sections spaced apart around the central section.

16. The localized patient support of claim 1, further comprising a first outer skin covering the base and a second outer skin covering the annular ring.

17. The localized patient support of claim 16, wherein the first and second outer skins comprise urethane coated knitted fabric.

18. The localized patient support of claim 1, wherein each bladder of the plurality of bladders has an upwardly-facing surface that is attached to a downwardly-facing surface of the associated section of the plurality of gel pads.

19. The localized patient support of claim 1, wherein each bladder of the plurality of bladders has a downwardly-facing surface that is attached to an upwardly facing surface of the base.

20. The localized patient support of claim 1, wherein the sections of the gel pad comprise a central section and a plurality of peripheral sections.
