Abstract

A system for preventing and treating pressure sores of a bed-ridden patient including an array of expandable and collapsible supports to support and provide pressure relief to a patient in pressure locations where the expandable and collapsible supports support the patient; pressure sensors associated with the expandable and collapsible supports to monitor pressure locations where the expandable and collapsible supports support the patient; and a patient lift movable between the expandable and collapsible supports to raise and lower the patient between at least a position where the patient is primarily supported by the array of expandable and collapsible supports and a position above the expandable and collapsible supports where the patient is primarily supported by the patient lift.

Claims

1. A system for preventing and treating pressure sores of a patient, comprising:

an array of expandable and collapsible supports to support and provide pressure relief to a patient in pressure locations where the expandable and collapsible supports support the patient;

pressure sensors associated with the expandable and collapsible supports to monitor pressure locations where the expandable and collapsible supports support the patient;

a patient lift movable between the expandable and collapsible supports to raise and lower the patient between at least a position where the patient is primarily supported by the array of expandable and collapsible supports and a position above the expandable and collapsible supports where the patient is primarily supported by the patient lift,

wherein the array of expandable and collapsible supports include interstitial spaces between the expandable and collapsible supports, and one or more emitters are disposed in the interstitial spaces, the one or more emitters include one or more of air emitters, oxygen emitters, and water emitters.

2. The system of claim 1, wherein the patient lift includes a plurality of holes, one hole per expandable and collapsible support, that the expandable and collapsible supports are respectively disposed within when the patient lift is raised and lowered.

3. The system of claim 2, wherein the patient lift is a top mattress.

4. The system of claim 3, wherein the patient lift is an air-filled mattress.

5. The system of claim 1, wherein the system is integrated into a hospital bed.

6. The system of claim 1, wherein the system is a seat that is a member of the group consisting of wheel chair seating, seats in automobiles, seats in airplanes, workplace seats in factories, workplace seats in offices, and back massage chairs.

7. The system of claim 1, wherein the lift includes multiple actuators operably associated with the patient lift to raise and lower the patient lift.

8. The system of claim 1, further including a bottom air filled mattress with the array of expandable and collapsible supports.

9. The system of claim 1, wherein the expandable and collapsible supports are inflatable balloons.

10. The system of claim 9, wherein pressure sensors are respectively associated with the inflatable balloons, and further including a controller operably associated with the pressure sensors and the inflatable balloons to control the inflation of the inflatable balloons based on the sensed pressure by the pressure sensors to prevent pressure sores.

11. A system for preventing and treating pressure sores of a patient, comprising:

an array of expandable and collapsible supports to support and provide pressure relief to a patient in pressure locations where the expandable and collapsible supports support the patient;

pressure sensors associated with the expandable and collapsible supports to monitor pressure locations where the expandable and collapsible supports support the patient;

a patient lift movable between the expandable and collapsible supports to elevate one or more areas of the patient, the patient lift including one or more air emitters, oxygen emitters, and water emitters to aerate one or more areas of the patient, oxygenate one or more areas of the patient, and/or rinse one or more areas of the patient,

wherein the array of expandable and collapsible supports include interstitial spaces between the expandable and collapsible supports and the one or more emitters are disposed in the interstitial spaces.

12. The system of claim 11, wherein the expandable and collapsible supports provide pressure relief and the one or more emitters provide aeration, oxygenation, and/or rinsing without elevating the patient with the patient lift.

13. The system of claim 11, wherein the lift includes one or more hinges, enabling the lift to lift the patient'"'"'s torso alone, the patient'"'"'s lower extremities alone, or the patient'"'"'s entire body.

14. The system of claim 11, wherein the expandable and collapsible supports touch adjacent expandable and collapsible supports on all sides upon expansion so that the array of expandable and collapsible supports make a contiguous mattress except that the expandable and collapsible supports are unstitched.

15. A system for preventing and treating pressure sores of a patient, comprising:

an array of expandable and collapsible supports to support and provide pressure relief to a patient in pressure locations where the expandable and collapsible supports support the patient;

pressure sensors associated with the expandable and collapsible supports to monitor pressure locations where the expandable and collapsible supports support the patient;

a patient lift movable between the expandable and collapsible supports to elevate one or more areas of the patient, the patient lift including one or more air emitters, oxygen emitters, and water emitters to aerate one or more areas of the patient, oxygenate one or more areas of the patient, and/or rinse one or more areas of the patient, wherein the lift includes horizontal supports disposed between the expandable and collapsible supports, and the horizontal supports include the one or more emitters.

16. The system of claim 15, wherein the expandable and collapsible supports touch adjacent expandable and collapsible supports on all sides upon expansion so that the array of expandable and collapsible supports make a contiguous mattress except that the expandable and collapsible supports are unstitched.
