Abstract

A method for monitoring pressure at one or more points on an individual and automatically adjusting one or more sections of a support structure. The method includes periodically receiving pressure data from one or more radio frequency addressable sensors placed on an individual; determining, based on the received pressure data, whether an adjustment in the support structure is required; systematically adjusting cells located within the plurality of zones, one zone at a time, until an improvement in pressure data is indicated. If an improvement in pressure data is indicated for a zone, systematically adjusting cells within the plurality of subzones for that zone, one subzone at a time, until an improvement in pressure data is indicated. If an improvement in pressure data is indicated for a subzone, systematically adjusting cells in that subzone, one cell at a time, until an improvement in pressure data is indicated.

Claims

1. A method for monitoring pressure at one or more points on an individual and automatically adjusting one or more sections of a support structure having a plurality of adjustable cells, wherein the support structure is divided into a plurality of zones and one or more of the zones is divided into a plurality of subzone, the method comprising:

periodically receiving with one or more processors, localized contact pressure data from one or more radio frequency (RF) addressable sensors placed on an individual;

determining whether an adjustment in the support structure is required using the received localized contact pressure data

when an adjustment is required, systematically adjusting cells located within the plurality of zones, one zone at a time, until a required change in localized pressure data is indicated;

if the required change in localized pressure data is indicated for a zone, systematically adjusting cells within, the plurality of subzones for that zone, one subzone at a time, until the required change in localized pressure data is indicated; and

if the required change in localized pressure data is indicated for a subzone, systematically adjusting cells in that subzone, one cell at a time, until the required change in localized pressure data is indicated.

2. The method of claim 1, further comprising receiving a tag identification number for each of the one or more RI'"'"' addressable sensors.

3. The method of claim 1, wherein receiving localized contact pressure data from one or more RF addressable sensors includes polling the RF addressable sensors.

4. The method of claim 1, wherein determining whether an adjustment is required includes determining whether the received localized contact pressure data from one or more of the RF addressable sensors exceeds a threshold.

5. The method of claim 1, wherein determining whether an adjustment is required is based on a historical trend for one or more of the RF addressable sensors.

6. The method of claim 5, wherein the historical trend includes information indicating that the received localized contact pressure data has increased over a predetermined period of time.

7. The method of claim 1, wherein an order for systematically adjusting one or more zones is based on the likely position of the individual on the support structure.

8. The method of claim 1, wherein an order for systematically adjusting one or more zones is based on the likelihood or severity of a pressure injury occurring in the zone.

9. The method of claim 1, wherein determining whether an adjustment in the support stricture is required is based on whether the received localized contact pressure data is below a threshold pressure.

10. The method of claim 1, further comprising

sending an alert to an external monitoring station if the required change in the pressure data is not indicated after the adjustments are completed.

11. The method of claim 1, further comprising:

maintaining the adjustments for a predetermined period of time; and

receiving updated localized contact pressure data from the one or more RF addressable sensors.

12. The method of claim 11, further comprising:

returning one or more of the adjustable sections to a pre-adjusted level following the predetermined period of time.

13. The method of claim 1, wherein adjusting one or more identified sections includes inflating one or more of the identified sections.

14. The method of claim 1, wherein adjusting one or more identified sections includes deflating one or more of the identified sections.

15. A system for preventing and/or treating pressure wounds on an individual, the system comprising:

a support structure including a plurality of adjustable cells, wherein the support structure is divided into a plurality of zones and one or more of the zones is divided into a plurality of subzones;

an RFID sensor reader configured to receive localized contact pressure data from one or more RF addressable sensors placed adjacent to the skin of the individual;

a processor coupled to the support structure and the RE sensor reader, wherein the processor is configured to;

determine whether the localized contact pressure data in an RF addressable sensor in the one or more RF addressable sensors exceeds a predetermined threshold, and

isolate a location on the individual of the RF addressable sensor by systematically adjusting the adjustable cells in the plurality of zones, one zone at a time until a required change in the localized contact pressure data is indicated for a zone and adjusting the adjustable cells in the plurality of subzones for that zone, one subzone at a time, until the required change in the localized contact pressure data is indicated.

16. The system of claim 15, further comprising an actuator coupled to the processor and the one or more adjustable cells.

17. The system of claim 16, further comprising a hose assembly connected to the one or more adjustable sections, the hose assembly comprising:

a means of introducing pressure;

a central line operatively connected to the means of introducing pressure; and

one or more branch lines operatively connected to the central line and operatively connected to the one or more adjustable sections,

wherein the hose assembly is configured to adjust the one or more identified sections.

18. The system of claim 17, wherein the hose assembly is configured to adjust the one or more identified sections with air pressure.

19. The system of claim 17, wherein the hose assembly is configured to adjust the one or more identified sections with fluid pressure.

20. The system of claim 15, wherein the RF addressable sensor is included in a bandage affixed to the skin of the individual.

21. The system of claim 15, wherein the support structure is a bed.

22. The system of claim 15, wherein the support structure is a pad configured for use on a bed.

23. The system of claim 15, wherein the support structure is a chair.

24. The system of claim 15, wherein the support structure is a wheel chair.

25. The system of claim 15, wherein the support structure is a pad configured for use on a chair.
