Abstract

A patient support surface including a cover defining an interior region, a layer of three dimensional material, located at the interior region, and an air circulation device disposed adjacent the layer of three dimensional material. The patient support surface includes at least one of a percussion device and a vibration device, located at the interior region.

Claims

1. A patient support surface comprising:

a cover having a support surface, a first side substantially perpendicular to the support surface and a second side spaced from the first side, the second side being substantially perpendicular to the support surface, the cover defining an enclosed interior region, the interior region comprising

a layer of three dimensional material including a network of thermoplastic fibers;

an air circulation device disposed adjacent the layer of three dimensional material configured to direct air through the three-dimensional material;

by causing the air to enter the interior region at the first side of the cover, flow through the interior region, and exit the interior region at the second side of the cover,

at least one of a percussion device and a vibration device, and

a plurality of support pieces arranged adjacent a perimeter of the patient support surface, each piece comprising a wall, and at least one of the pieces defining a space in the wall to support the air circulation device.

2. The patient support surface of claim 1 further comprising a bladder, disposed at the interior region, the bladder being inflatable and adapted to provide at least one of turning and rotation.

3. The patient support surface of claim 2, further comprising a plurality of cushions, disposed at the interior region.

4. The patient support surface of claim 3, further comprising a plurality of sensors, disposed at the interior region, to sense at least one of a pressure and a force.

18. The patient support surface of claim 1, further comprising at least one x-ray slot defined by a low friction material within the interior region and configured to receive an x-ray cassette disposed at the interior region.

19. The patient support surface of claim 1, further comprising at least one section of air cushions, wherein the at least one section of air cushions comprises a plurality of spaced-apart upstanding air cells.

5. A patient support surface comprising:

a cover defining an enclosed interior region, the interior region comprising;

a layer of three dimensional material, the three-dimensional material including a network of thermoplastic fibers;

an air circulation device disposed adjacent the layer of three dimensional material; and

a hose defining a channel within the interior region, the hose having a first end and a second end spaced from the first end,

a first connector adjacent the cover and adapted to couple the first end of the hose to a first external device and a second connector spaced from the first connector adjacent the cover and adapted to couple the second end of the hose to a second external device.

6. The patient support surface of claim 5, further wherein the first connector is adapted to couple to an airway clearance device.

7. The patient support surface of claim 5, further comprising a plurality of cushions, disposed at the interior region.

8. The patient support surface of claim 7, further comprising a plurality of sensors, disposed at the interior region, to sense at least one of a pressure and a force.

9. A patient support surface comprising:

a support surface including a cover defining an enclosed interior region, the interior region comprising;

a layer of three dimensional material, the three-dimensional material including a network of thermoplastic fibers, a first blower disposed adjacent the layer of three dimensional material, a second blower spaced apart from the first blower;

at least one of a percussion and a vibration device, and

a plurality of bolsters adjacent a perimeter of the patient support surface, the bolsters being arranged to support the first blower and the second blower,

wherein the first blower and second blower are configured to direct air through the layer of three dimensional material.

10. The patient support surface of claim 9, wherein the surface further comprises a bladder, disposed at the interior region, the bladder being inflatable and adapted to provide at least one of turning and rotation.

11. The patient support surface of claim 10, wherein the frame comprises an integrated device, including a coupler adapted to couple to an airway clearance device.

12. The patient support surface of claim 11, further comprising a plurality of cushions, disposed at the interior region.

13. The patient support surface of claim 12, further comprising a plurality of sensors, disposed at the interior region, to sense at least one of a pressure and a force.

14. A patient support surface having a head end including a pair of lateral sides and a foot end comprising:

a cover defining an interior region;

a layer of three dimensional material, located in the interior region, the three-dimensional material including a network of thermoplastic fibers;

an air circulation device disposed adjacent the layer of three dimensional material;

a head elevation device, located in the interior region at the head end of the patient support surface, the head elevation device including a support surface having a plurality of hinge points to alternatingly laterally elevate the lateral sides of the head end of the patient support surface;

a head of bed indicator configured to indicate when predetermined angles of head elevation are reached; and

at least one of a percussion device and a vibration device, located at the interior region.

15. The patient support surface of claim 14, further comprising a bladder, disposed at the interior region, the bladder being inflatable and adapted to provide at least one of turning and rotation.

16. The patient support surface of claim 15, further comprising a plurality of cushions, disposed at the interior region.

17. The patient support surface of claim 16, further comprising a plurality of sensors, disposed at the interior region, to sense at least one of a pressure and a force.
