Person support apparatus with ingress/egress assist
Embodiments include a person support apparatus including a plurality of air fluidizable material, a tub, a foam bolster disposed along at least one wall of the tub and extending over the at least one wall, and an inflatable air bladder disposed above the foam bolster along the at least one wall of the tub. A method of assisting a person with ingress or egress of a person support apparatus by deflating the inflatable air bladder and adjusting a level of fluidization of the air fluidizable material such that the surface supporting the portion of the person is substantially level with a top of the foam bolster is also described.
1. A person support apparatus comprising:
a first surface for supporting a first portion of a person, the first surface comprising a plurality of fluid bladders; and
a second surface for supporting a second portion of the person, the second surface comprising an air fluidizable material contained in a tub having a foam bolster disposed along an internal surface of at least one wall of the tub and an inflatable air bladder disposed above the foam bolster along the at least one wall of the tub, wherein the foam bolster is in direct contact with the tub;
a bladder cover extending along an exterior surface of the at least one wall of the tub, over the inflatable air bladder, and between the second surface and the foam bolster and the inflatable air bladder;
wherein the tub comprises a lip extending perpendicularly from a top of the at least one wall of the tub, and wherein the foam bolster extends above the lip.
2. The person support apparatus according to claim 1 , wherein the inflatable air bladder comprises a plurality of zones, wherein each of the zones is separately and individually inflatable and deflatable.
3. The person support apparatus according to claim 2 , further comprising a controller to separately and individually control the inflation of the plurality of fluid bladders of the first surface and each of the zones of the inflatable air bladder.
4. The person support apparatus according to claim 3 , wherein the foam bolster comprises a channel along a top portion of the foam bolster for receiving one or more tubes for inflating the one or more zones of the inflatable air bladder.
5. The person support apparatus according to claim 4 , wherein the plurality of zones comprises a lumbar zone positioned adjacent to the first surface, an ingress/egress zone positioned along a left side and a right side of the person support apparatus, and a foot zone positioned along a foot end of the person support apparatus.
6. The person support apparatus according to claim 5 , wherein the foot zone extends partially along the left side and the right side of the person support apparatus.
7. A system for providing support to a person comprising:
a person support apparatus comprising:
an air fluidizable material;
a tub containing the air fluidizable material, the tub including a plurality of walls, each of the plurality of walls having an internal surface;
a foam bolster disposed along the internal surface of each of the plurality of walls of the tub and extending over each of the plurality of walls, wherein the foam bolster is in direct contact with the tub; and
an inflatable air bladder disposed above the foam bolster along each of the plurality of walls of the tub, the inflatable air bladder comprising a plurality of zones, wherein each of the zones is separately and individually inflatable and deflatable;
a bladder cover extending along an exterior surface of the at least one wall of the tub, over the inflatable air bladder, and between the air fluidizable material and the foam bolster and the inflatable air bladder; and
a controller configured to separately and individually control the inflation of the plurality of zones of the inflatable air bladder.
8. The system of claim 7 , wherein each of the plurality of walls of the tub includes a lip extending substantially perpendicular to a height of each of the plurality of walls.
9. The system of claim 8 , wherein the foam bolster extends above the lip of each of the plurality of walls.
10. The system of claim 7 , wherein the foam bolster comprises a channel along a top portion of the foam bolster for receiving one or more tubes for inflating the inflatable air bladder.
11. The system of claim 7 , wherein the plurality of zones comprises a lumbar zone positioned adjacent to a first surface, an ingress/egress zone positioned along a left side and a right side of the person support apparatus, and a foot zone positioned along a foot end of the person support apparatus.
12. The system of claim 11 , wherein the controller causes the ingress/egress zone to be deflated while maintaining inflation of one or more of the lumbar zone and the foot zone.
13. The system of claim 7 , the person support apparatus further comprises a surface formed by a plurality of air bladders to support a first portion of a person while the air fluidizable material supports a second portion of the person.
14. The system of claim 13 , wherein the controller is further configured to control the inflation of the plurality of air bladders.
