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.
Claims22
A patient support system comprising:
- a spacer material;
- a shell, wherein:
- the 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 configured to pull air through the spacer material and toward the air mover.
4 more elements
A patient support system comprising:
- a first layer comprising a vapor permeable material;
- a second layer comprising a flexible material configured to allow lateral movement of air under a compressive load of a patient;
- 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 reduce pressure within the flexible material, wherein the first layer comprises an aperture configured to allow suction air flow through the aperture and into the second layer.
2 more elements
A patient support system comprising:
- a first layer comprising a vapor permeable material;
- a second layer comprising a flexible material configured to allow lateral movement of air under a compressive load of a patient;
- a third layer, wherein the second layer is between the first layer and the third layer;
- an air mover, wherein:
- the air mover is configured to reduce pressure within the flexible material;
- the first layer comprises a center section and two side sections;
