Abstract
In various embodiments, a support system includes a multi-layer support system with a number of layers. Systems and methods of removing moisture vapor from an environment surrounding patient are disclosed that accomplish such removal.
Claims38
A support system comprising:
- a first layer comprising a material that allows moisture to pass through the first layer while substantially preventing air from passing through the first layer;
- a second layer secured to the first layer so as to form an airtight seal at sides and one end and so as to form an opening at another end opposite the one end, wherein the second layer comprises
- a base layer;
- and
- a plurality of protrusions disposed on the base layer and extend towards the first layer, wherein the protrusions comprise a plurality of permanently air-filled, substantially airtight, independent, encapsulated cells, wherein the first layer is in partial contact with the protrusions such that the protrusions form a plurality of channels between the first layer and the second layer;
- and
- an air mover, wherein the air mover is configured to pull air through the opening and through the plurality of channels formed between the first layer and the second layer and toward the air mover, or the air mover is configured to push air away from the air mover and through the plurality of channels formed between the first layer and the second layer and through the opening.

A support system comprising:
- a first layer comprising a vapor-permeable, liquid-impermeable, substantially air impermeable material for allowing moisture to pass through said first layer while substantially preventing air from passing through said first layer;
- and
- a second layer comprising a cellular cushioning material, the cellular cushioning material comprising a plurality of encapsulated, independent, permanently air-filled volumes, and being vapor-impermeable and liquid-impermeable and having thermoplastic properties;
- wherein the first layer is in partial contact with tops of the encapsulated, air-filled volumes of the second layer and forms an airtight seal with the second layer such that the encapsulated, air-filled volumes define a plurality of channels between the first layer and the second layer;
- and
- an air mover for circulating air through the plurality of channels.

A support system comprising:
- a first layer comprising a vapor-permeable, liquid-impermeable, substantially air impermeable material for allowing moisture to pass through said first layer while substantially preventing air from passing through said first layer;
- a second layer comprising:
- a vapor-impermeable and liquid-impermeable material;
- and
- a plurality of protrusions forming a plurality of permanently air-filled, substantially airtight, independent, encapsulated cells;
- wherein the first layer is in partial contact with the second layer such that the encapsulated cells define a plurality of channels between the first layer and the second layer;
- and
- an air mover for moving air through the plurality of channels,
- wherein the support system is configured to be coupled to a mattress.
