Abstract
In various embodiments, a support system includes a multi-layer cover sheet with a number of layers. In certain embodiments, a source to move air inside and outside the multi-layer cover sheet can be provided. The source can include a source of positive pressure or negative pressure.
Claims51
A patient support system comprising:
- a first layer comprising a vapor permeable material;
- a second layer comprising a spacer material;
- a third layer, wherein the second layer is between the first layer and the third layer;
- and
- an air mover, wherein the air mover is configured to pull air through the spacer material and toward the air mover.
2 more elements
A patient support system comprising:
- a flexible spacer material;
- a shell, wherein:
- the flexible spacer material is at least partially encased in the shell;
- and
- a first portion of the shell is vapor permeable;
- and
- an air mover, wherein the air mover is in fluid communication with a first aperture in the shell and the air mover is configured to draw air through the spacer material.
4 more elements
A method of removing moisture vapor from a person, the method comprising:
- providing a support surface to support the person;
- and
- providing a cover sheet between the support surface and the person, wherein the cover sheet comprises:
- a vapor permeable material proximal to the person;
- a spacer material between the vapor permeable material and the support surface;
- and
- an air mover configured to pull air through the spacer material.
4 more elements
A support system for supporting a person, the support system comprising:
- an upper portion comprised of a first spacer material that allows air to flow through the upper portion;
- a lower portion comprised of a second material that is air impermeable;
- an aperture in the second material;
- and
- an air mover configured to draw air through the aperture and the first spacer material.
2 more elements
A system comprising:
- a cover sheet, wherein the cover sheet comprises a first layer that is moisture vapor permeable;
- a support mattress;
- and
- an air mover comprising an air inlet and an air outlet, wherein the air inlet is coupled to the cover sheet and the air outlet is coupled to the support mattress.
1 more element
A patient support system comprising:
- a vapor permeable upper portion;
- a lower portion comprising a spacer material encased within a shell;
- and
- an air mover that is integral with the shell.
1 more element
A multi-layer cover sheet, comprising:
- a first layer formed of a vapor permeable material;
- a second layer formed of a flexible material, the flexible material to facilitate at least a flow of a vapor entering the second layer through the first layer;
- a third layer formed of a liquid impermeable, gas impermeable, and vapor impermeable material;
- and
- a source of negative pressure configured to draw air through the flexible material.
