An array of balloons touching each other form a mattress of unstitched but contiguous balloons like in a conventional mattress with stitched puffs. Individual pressure sensors placed within each balloon measure and monitor pressure. Furthermore, horizontal rods which lay between the balloons perform oxygenation and provide water massage to the back of the patient body from the interstitial spaces within the unstitched mattress of contiguous balloons. The rods are elevated to raise the patient above the mattress to relieve overall pressure and enable cleaning and wipe down of the back of the patient body. The rods can elevate the entire patient body or its torso alone or the lower extremities alone to clean as desired. ## Claims ### Claim 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 elevate one or more areas of the patient, the patient lift including at least one of one or more oxygen emitters to oxygenate one or more areas of the patient and one or more water emitters to rinse one or more areas of the patient, 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. ### Claim 2 (depends on 1) The system of claim 1, wherein the system is a hospital bed. ### Claim 3 (depends on 1) 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. ### Claim 4 (depends on 1) The system of claim 1, wherein the lift includes multiple actuators that elevate the patient to clean a back of the patient. ### Claim 5 (depends on 1) The system of claim 1, wherein the expandable and collapsible supports provide pressure relief and the one or more oxygen emitters provide oxygenation without elevating the patient with the patient lift. ### Claim 6 (depends on 1) The system of claim 1, wherein the expandable and collapsible supports are inflatable balloons. ### Claim 7 (depends on 6) The system of claim 6, wherein the inflatable balloons are embedded with the pressure sensors. ### Claim 8 (depends on 1) The system of claim 1, 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. ### Claim 9 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 at least one of one or more oxygen emitters to oxygenate one or more areas of the patient and one or more water emitters to 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 at least one of the one or more oxygen emitters are disposed in the interstitial spaces to emit oxygen there through to oxygenate one or more areas of the patient and the one or more water emitters are disposed in the interstitial spaces to rinse one or more areas of the patient. ### Claim 10 (depends on 9) The system of claim 9, 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. ### Claim 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 at least one of one or more oxygen emitters to oxygenate one or more areas of the patient and one or more water emitters to rinse one or more areas of the patient, wherein the lift includes horizontal rods disposed between the expandable and collapsible supports, and the horizontal rods include the at least one of the one or more oxygen emitters and the one or more water emitters. ### Claim 12 (depends on 11) 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.
