Abstract

A transfer system includes an air-bearing support with first and second longitudinal sections. A port is provided in flow communication with the first and second longitudinal sections, and configured for inflation of the air-bearing support for transfer of a patient or other body. A selective coupling extends between the first and second longitudinal sections, adapted to attach the first and second sections together for transfer of the body on the air-bearing support, and to at least partially detach the first and second longitudinal sections for separation and removal, e.g., upon deflation of the patient support, after the transfer is accomplished.

Claims

1. A transfer system comprising:

an air-bearing support having first and second longitudinal sections with a split extending therebetween, the split adapted for at least partially separating the first and second longitudinal sections;

a port in flow communication with the first and second longitudinal sections, the port configured for inflation of the air-bearing support for transfer of a body thereon; and

a selective coupling extending along the split between the first and second longitudinal sections, the selective coupling configured to attach the first and second longitudinal sections together for transfer of the body on the air-bearing support, and to at least partially detach the first and second longitudinal sections for removal of the air-bearing support from beneath the body;

wherein the selective coupling comprises a selectively releasable seam extending along the split between the longitudinal sections from a proximal end of the air-bearing support toward a distal end of the air-bearing support, the releasable seam configured to selectively detach the longitudinal sections at the proximal end and to separate the longitudinal sections along the split from the proximal end toward the distal end.

2. The transfer system of claim 1, wherein the releasable seam is configured to maintain attachment of the longitudinal sections for transfer of the body upon inflation of the air-bearing support, and to detach the longitudinal sections at the proximal end upon deflation of the air-bearing support and application of a manual force.

3. The transfer system of claim 1, wherein the selective coupling is configured for detachment of the longitudinal sections at the proximal end, for separation of the longitudinal sections to opposing sides of the body along the releasable seam, and for removal of the air-bearing support from beneath the body absent further substantial manipulation thereof.

4. The transfer system of claim 1, further comprising a plurality of baffles disposed in the one or both of the first and second longitudinal sections, the baffles extending vertically between bottom and top surfaces of the air-bearing support to provide structural integrity upon inflation thereof.

5. The transfer system of claim 1, further comprising a plurality of flow apertures disposed on a bottom surface of the air-bearing support, the plurality of apertures configured for airflow between the air-bearing support and one or more surfaces across which the transfer of the body is accomplished.

6. The system of claim 1, wherein the releasable seam is adapted for removing the longitudinal sections from beneath the body without rolling the body to one side or another.

7. The system of claim 1, wherein the body has a weight of 100 pounds or 450 N, or heavier.

8. The system of claim 7, wherein the weight is up to 500 pounds or 2250 N.

9. The system of claim 1, wherein the body is a bariatric or obese patient.

10. The system of claim 9, wherein the patient has a BMI of up to 53.

11. A patient transfer apparatus comprising:

an air-bearing patient support having a transverse section with first and second longitudinal sections extending therefrom;

a port in flow communication with the first and second longitudinal sections via the transverse section, the port configured for inflation of the air-bearing patient support for transfer of a patient on a top surface thereof;

a plurality of flow apertures disposed on a bottom surface of the air-bearing patient support, the flow apertures configured for airflow from an interior of the air-bearing patient support during the transfer; and

a selectively engaged seam extending between the first and second longitudinal sections from a proximal end of the air-bearing support toward a distal end of the air-bearing support, the selectively engaged seam configured to maintain attachment of the longitudinal sections along the selectively engaged seam for transfer of the patient upon inflation on the air-bearing support, and for selective detachment of the longitudinal sections from the proximal end toward the distal end for separation and removal of the longitudinal sections upon deflation of the air-bearing support;

wherein the selectively engaged seam is configured for separation and removal of the longitudinal sections to opposing sides of the patient.

12. The apparatus of claim 11, wherein the selectively engaged seam extends between the first and second longitudinal sections over a length of the air-bearing patient support for complete separation and removal of the longitudinal sections as distinct components.

13. The apparatus of claim 11, wherein the selectively engaged seam extends to a transverse section of the air-bearing patient support, the transverse section joining the longitudinal sections for removal together as a unit.

14. The apparatus of claim 11, wherein the selectively engaged seam is adapted to define a substantially continuous top surface of the air-bearing patient support across the selectively engaged seam extending between the first and second longitudinal sections and the selectively engaged seam defines a vertical web attachment structure between the first and second longitudinal sections.

15. The apparatus of claim 11, further comprising a plurality of vertical baffles extending transversely within and across one or both of the first and second longitudinal sections, the baffles further extending vertically between bottom and top surfaces of the air-bearing patient support and configured to admit longitudinal airflow upon inflation thereof.

16. The apparatus of claim 11, further comprising first and second panels defining the top and bottom surfaces of the air-bearing patient support, respectively, wherein the first and second panels are bonded about a perimeter to define the first and second longitudinal sections with the selectively engaged seam extending therebetween.

17. The apparatus of claim 16, wherein the perimeter defines a release feature for the selectively engaged seam, the release feature adapted for detachment of the first and second longitudinal sections by separation of the selectively engaged seam at the perimeter, in response to a transverse force.

18. The apparatus of claim 11, wherein the selectively engaged seam is configured to selectively detach the first and second longitudinal sections in response to a transverse force, for separation and removal of the longitudinal sections absent further manipulation of the patient in a torso region thereof.

19. The apparatus of claim 11, wherein the patient has a weight of 100 pounds (or 450 N) or heavier, and the selectively engaged seam is adapted for removing the longitudinal sections from beneath the patient without rolling the patient to one side or another.

20. The apparatus of claim 19, wherein the patient is bariatric or obese.

21. A transfer system comprising:

an air-bearing support having first and second longitudinal sections with a split extending therebetween, the split adapted for at least partially separating the first and second longitudinal sections;

a port in flow communication with the first and second longitudinal sections, the port configured for inflation of the air-bearing support for transfer of a body thereon; and

a selective coupling extending along the split between the first and second longitudinal sections, the selective coupling configured to attach the first and second longitudinal sections together for transfer of the body on the air-bearing support, and to at least partially detach the first and second longitudinal sections for removal of the air-bearing support from beneath the body;

wherein the selective coupling comprises a selectively releasable seam extending along the split between the longitudinal sections from a proximal end of the air-bearing support toward a distal end of the air-bearing support, the releasable seam configured to selectively detach the longitudinal sections at the proximal end and to separate the longitudinal sections along the split from the proximal end toward the distal end; and

one or more apertures disposed along the selectively releasable seam and configured for transverse airflow across the split between the first and second longitudinal sections upon inflation thereof.
