Abstract

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.

First claim

What is claimed is:

1. A method of assisting a person with ingress or egress of a person support apparatus, the method comprising:
supporting a first portion of a person on a first surface formed by a plurality of fluid bladders;
supporting a second portion of a person on a second surface formed by an air fluidizable material contained within a tub, the 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, and a lip extending perpendicularly from a top of the at least one wall of the tub, wherein the foam bolster extends above the lip of the tub, and 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;
deflating a first portion of the inflatable air bladder disposed above the foam bolster; and
adjusting a level of fluidization of the air fluidizable material such that the second surface supporting the second portion of the person is substantially level with a top of the foam bolster.

2. The method of assisting a person with ingress or egress of a person support apparatus according to claim 1 , wherein the method further comprises maintaining inflation of one or more additional portions of the inflatable air bladder during deflation of the first portion.

3. The method of assisting a person with ingress or egress of a person support apparatus according to claim 2 , wherein the one or more additional portions of the inflatable air bladder extend along a foot end and partially along the sides of the person support apparatus.

4. The method of assisting a person with ingress or egress of a person support apparatus according to claim 3 , wherein the one or more additional portions of the inflatable air bladder comprise 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.

5. The method of assisting a person with ingress or egress of a person support apparatus according to claim 3 , further comprising separately and individually controlling the inflation of the one or more additional portions of the inflatable air bladder.

6. The method of assisting a person with ingress or egress of a person support apparatus according to claim 1 , 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 additional portions of the inflatable air bladder.
