Abstract

A support apparatus configured to support a person is provided. The support apparatus includes a top surface including one or more predetermined areas, one or more conduits located inside the support apparatus which are located proximate to the one or more predetermined areas, and an air supply configured to provide air to the one or more conduits for delivering to the one or more predetermined areas. The air supply includes a temperature sensor configured to measure a temperature of the air provided by the air supply, a cooling element, and a controller communicatively coupled to the temperature sensor and the cooling element. The controller determines whether the measured temperature of the air is higher than a predetermined temperature, and controls the cooling element to cool the air to the predetermined temperature if it is determined that the temperature of the air is higher than the predetermined temperature.

First claim

What is claimed is:

1. A support apparatus configured to be placed on a mattress and configured to support a person, the support apparatus comprising:
a top surface including a first predetermined area and a second predetermined area separated from the first predetermined area; and
an enclosed area comprising:
a first conduit and a second conduit located inside the enclosed area of the support apparatus, the first conduit connected to a first air pocket located proximate to the first predetermined area, the second conduit connected to a second air pocket located proximate to the second predetermined area; and
an air supply positioned inside the enclosed area of the support apparatus and directly connected to the first conduit and the second conduit, the air supply configured to provide air to the first and second conduits simultaneously for delivering to the first and second predetermined areas, wherein one end of each of the first and second conduits and the other end of each of the first and second conduits are directly connected to the air supply, the air supply comprising:

a temperature sensor configured to measure a temperature of the air provided by the air supply;
a cooling element; and
a controller communicatively coupled to the temperature sensor and the cooling element, the controller comprising at least one processor and at least one memory storing computer readable and executable instructions that, when executed by the processor, cause the controller to:
determine whether the measured temperature of the air is higher than a predetermined temperature; and
control the cooling element to cool the air to the predetermined temperature if it is determined that the temperature of the air is higher than the predetermined temperature,
wherein an entirety of the first air pocket is at a vertically higher position inside the enclosed area than an entirety of the first conduit, and an entirety of the second air pocket is at a vertically higher position than an entirety of the second conduit.

2. The support apparatus of claim 1 , further comprising
a self-powered generator supplying power to the air supply, the self-powered generator being located within the support apparatus.

3. The support apparatus of claim 2 , wherein the self-powered generator comprises one or more photoelectric cells.

4. The support apparatus of claim 1 , wherein the predetermined temperature is about 75° F.

5. The support apparatus of claim 1 , wherein the support apparatus comprises a plurality of pull straps attached to lateral sides of the support apparatus.

6. The support apparatus of claim 1 , wherein the first predetermined area comprises an area corresponding to a sacral area of the person when the person rests on the support apparatus.

7. The support apparatus of claim 1 , wherein the second predetermined area comprises an area corresponding to a heel area of the person when the person rests on the support apparatus.

8. The support apparatus of claim 1 , further comprising an air inlet for receiving compressed air from outside the support apparatus.

9. The support apparatus of claim 8 , wherein the air inlet comprises:
a check valve coupled to the air inlet and configured to receive the compressed air from an external compressor; and
a relief device configured to expel the compressed air within the support apparatus.

10. The support apparatus of claim 8 , wherein the support apparatus is configured to be filled with the compressed air such that the support apparatus is deformed less by a force applied in a direction orthogonal to the support apparatus than when the support apparatus is not filled with the compressed air.

11. The support apparatus of claim 1 , wherein the temperature sensor is located proximate to the one or more predetermined areas.

12. The support apparatus of claim 1 , further comprising
a temperature setting module, communicatively coupled to the air supply, the temperature setting module comprising:
a display; and
a tactile input hardware configured to receive input indication of a request to adjust the predetermined temperature.

13. The support apparatus of claim 1 , wherein the first and second predetermined areas of the top surface have a color different from a rest of the top surface.

14. The support apparatus of claim 1 , wherein boundaries of the first and second predetermined areas of the top surface are indicated on the top surface.

15. A person support system comprising:
a mattress; and
the support apparatus of claim 1 coupled to the mattress.

16. A support apparatus configured to be placed on a mattress and configured to support a person, the support apparatus comprising:
a top surface including a first predetermined area and a second predetermined area separated from the first predetermined area; and
an enclosed area comprising:
a first conduit and a second conduit located inside the enclosed area of the support apparatus, the first conduit connected to a first cooling conduit located proximate to the first predetermined area, the second conduit connected to a second cooling conduit located proximate to the second predetermined area; and
an air supply positioned inside the enclosed area of the support apparatus and directly connected to the first conduit and the second conduit, the air supply configured to provide air to the first and second conduits simultaneously for delivering to the first and second predetermined areas, wherein one end of each of the first and second conduits and the other end of each of the first and second conduits are directly connected to the air supply, the air supply comprising:

a temperature sensor configured to measure a temperature of the air provided by the air supply;
a cooling element; and
a controller communicatively coupled to the temperature sensor and the cooling element, the controller comprising at least one processor and at least one memory storing computer readable and executable instructions that, when executed by the processor, cause the controller to:
determine whether the measured temperature of the air is higher than a predetermined temperature; and
control the cooling element to cool the air to the predetermined temperature if it is determined that the temperature of the air is higher than the predetermined temperature,
wherein an entirety of the first cooling conduit is at a vertically higher position inside the enclosed area than an entirety of the first conduit, and an entirety of the second cooling conduit is at a vertically higher position than an entirety of the second conduit.

17. A support apparatus for supporting a person, the support apparatus comprising:
a top surface including a first predetermined area and a second predetermined area separated from the first predetermined area; and an enclosed area comprising:
first and second conduits located inside the enclosed area of the support apparatus, the first conduit including a first air pocket located proximate to the first predetermined area, the second conduit including a second air pocket located proximate to the second predetermined area;
an air supply positioned inside the enclosed area of the support apparatus and directly connected to the first conduit and the second conduit, the air supply configured to provide air to the first and second conduits simultaneously for delivering to the first and second predetermined areas, the air supply comprising a cooling element configured to cool the air to a predetermined temperature, wherein one end of each of the first and second conduits and the other end of each of the fi
