Abstract

The present invention relates to a system and method for sacral and trochanteric support and off-loading. The system provides a ultra low pressure plenum and a positioner. The patient body size and size and corresponding surface area of the positioner control the amount of gas which is displaced evenly against the walls of the ultra low pressure plenum to allow the combination of the ultra low pressure plenum and the positioner to slightly lift a patient from a bed surface, thereby offloading the sacrum and trochanter. The positioner can be an ultra low pressure bladder.

First claim

What is claimed is:

1. A system for patient turning and positioning, comprising:
a first low pressure air plenum with a pressure that is less than about 20 mm of water;
a second low pressure air plenum with a pressure that is less than about 20 mm of water, the first and second low pressure air plenums comprising static air plenums with a fixed amount of air therein, the first and second low pressure static air plenums forming a mattress overlay,
wherein at least a portion of the first low pressure air plenum comprises a higher coefficient of friction than at least a portion of the second low pressure air plenum.

2. The system of claim 1 , wherein the first and second low pressure static air plenums are attached to one another.

3. The system of claim 1 , wherein the first low pressure air plenum is positioned below the second low pressure air plenum.

4. A system for patient turning and positioning, comprising:
a plenum comprising a fixed amount of static gas therein, the plenum comprising an upper bladder having a first width configured to a shape to fit underneath a patient's back and an extension bladder having a second width that is smaller than the first width,
wherein at least a portion of the extension bladder comprises a higher coefficient of friction than at least a portion of the upper bladder.

5. The system of claim 4 , further comprising at least one first set of gripping handles configured to be located at an edge of the upper bladder and at least one second set of gripping handles configured to be located at an edge of the extension bladder, wherein the at least one second set of gripping handles allows the extension bladder to be folded underneath the upper bladder.

6. The system of claim 5 , further comprising a cover configured to receive the plenum, wherein the at least one first and second sets of gripping handles are attached to the cover.

7. The system of claim 5 , wherein gripping at least one handle of the first set of gripping handles creates a sling that allows a patient positioned on the plenum to be turned or moved.

8. The system of claim 5 , wherein the at least one first set of gripping handles comprises a plurality of handles positioned along left and right sides of the upper bladder.

9. The system of claim 5 , wherein the at least one second set of gripping handles comprises at least one handle positioned along a left side of the extension bladder and at least one handle positioned along a right side of the extension bladder.

10. The system of claim 4 , further comprising a cover configured to receive the plenum, wherein at least a portion of the cover that receives the extension bladder comprises a higher coefficient of friction than at least a portion of the cover that receives the upper bladder.

11. The system of claim 4 , further comprising a cover configured to receive the plenum, wherein the cover comprises a first surface having a first coefficient of friction and a second surface having a second coefficient of friction.

12. The system of claim 11 , wherein the first coefficient of friction is different from the second coefficient of friction.

13. The system of claim 12 , wherein the first coefficient of friction is provided on the at least a portion of the extension bladder that comprises a higher coefficient of friction than at least a portion of the upper bladder, and wherein the second coefficient of friction is provided on at least a portion of the upper bladder.

14. The system of claim 4 , wherein the plenum comprises a profile configured to be positioned underneath sheets of a bed.

15. The system of claim 4 , wherein the fixed amount of static gas in the plenum comprises a constant pressure below about 20 mm of water.

16. The system of claim 4 , wherein the fixed amount of static gas in the plenum comprises a constant pressure below about 5 mm of water.

17. The system of claim 4 , further comprising a positioner configured to be positioned beneath the plenum in use.

18. The system of claim 4 , wherein, in a first configuration, the extension bladder is coplanar with the upper bladder, and wherein, and a second configuration, the extension bladder is folded underneath at least a portion of the upper bladder.

19. The system of claim 4 , wherein the upper bladder is configured to be positioned beneath a patient's back and wherein the extension bladder is configured to be positioned beneath a patient's legs.

20. A system for patient turning and positioning, comprising:
a plenum comprising a fixed amount of static gas therein, the plenum comprising an upper bladder having a first width configured to a shape to fit underneath a patient's back and an extension bladder having a second width that is smaller than the first width,
wherein at least a portion of the extension bladder comprises a first coefficient of friction and wherein at least a portion of the upper bladder comprises a second coefficient of friction.

21. The system of claim 20 , wherein, in a first configuration, the extension bladder is coplanar with the upper bladder, and wherein, and a second configuration, the extension bladder is folded underneath at least a portion of the upper bladder.

22. The system of claim 21 , wherein the first coefficient of friction is such that the extension bladder is prevented from slipping when folded underneath at least a portion of the upper bladder.

23. The system of claim 20 , wherein the upper bladder is configured to be positioned beneath a patient's back and wherein the extension bladder is configured to be positioned beneath a patient's legs.
