Moisture drying mattress with separate zone controls

A moisture drying mattress comprising:

• at least one cushion having opposite top and bottom surfaces and a plurality of apertures extending through the cushion from the bottom surface to the top surface;
• a plurality of air channel mats, each air channel mat having a base and being dimensioned and adapted to fit beneath the at least one cushion and support the at least one cushion bottom surface in a spaced relation from the base;
• a cover over said at least one cushion defining a vapor evaporating area below the cover at the at least one cushion;
• and
• a selectively operable air pump for selectively supplying an air flow to the plurality of air channel mats, the air flow supplied to the mats flowing over the mats between the base and the cushion bottom surface and upwardly through the cushion apertures to evaporate moisture in the vapor evaporating area, but not flowing through the cover to contact the skin of a user positioned on the mattress.

A moisture drying mattress comprising:

• at least one cushion having opposite top and bottom surfaces and a plurality of apertures extending through the cushion from the bottom surface to the top surface;
• at least one air channel mat, the at least one air channel mat having a base and being dimensioned and adapted to fit beneath the at least one cushion and support the at least one cushion bottom surface in a spaced relation from the base;
• a cover encasing said at least one cushion and said at least one air channel mat and defining a space at the least one cushion and said at least one air channel mat, said cover being pervious to moisture vapor but impervious to liquid from outside the cover whereby moisture vapor can pass through said cover into said space, the cover further comprising a top sheet with a peripheral edge and a bottom sheet with a peripheral edge, the top sheet and bottom sheet being connected together along portions of their peripheral edges leaving an opening between their peripheral edges that provides access to an interior of the cover between the top sheet and bottom sheet, the bottom sheet having a plurality of pockets in the cover interior that are each dimensioned and adapted to receive one of the plurality of air channel mats in the pockets, each pocket covering a margin of the air channel mat top surface leaving an exposed portion of the base top surface where the projections of the exposed portion of the base top surface engage with the cushion bottom surface, and
• a selectively operable air pump for selectively supplying an air flow to the at least one air channel mat, the air flow supplied to the at least one air channel mat flowing through the air channel mat between the base and the cushion bottom surface and upwardly through the cushion apertures to remove moisture vapor which has passed through said cover and has accumulated in said space at said at least one cushion and said at least one air channel mat.

A moisture drying cushion for drying of moisture vapor associated with an individual positioned on the cushion, comprising:

• at least one cushion having opposite top and bottom surfaces and a plurality of apertures extending through the cushion from the bottom surface to the top surface;
• an air channel mat having a base with a peripheral edge and opposite top and bottom surfaces, the air channel mat being dimensioned and adapted to fit beneath the at least one cushion bottom surface and support the at least one cushion bottom surface;
• an air supply pump communicating with the air channel mat to supply an air flow to the air channel mat and through the air channel mat between the base top surface and the at least one cushion bottom surface and through the plurality of apertures in the at least one cushion;
• and a cover dimensioned and adapted to enclose the at least one cushion and the air distribution member thereby forming a vapor evaporation zone under the cover for the containment and drying of the moisture vapor permeating into the vapor evaporation zone through the cover, the cover having at least one exhaust opening therein.

A moisture vapor drying mattress assembly, comprising:

• at least one cushion having opposite top and bottom surfaces and a plurality of apertures extending through the cushion from the bottom surface to the top surface;
• at least one air distribution member having a base with a peripheral edge and opposite top and bottom sides, the air distribution member being dimensioned and adapted to fit beneath the at least one cushion bottom surface and support the at least one cushion bottom surface in a spaced relation from the base top side, each said air distribution member defining a moisture vapor drying zone;
• a top sheet that is pervious to moisture vapor but impervious to liquid defining a moisture vapor drying area comprising at least one moisture vapor drying zone under the top sheet;
• a bottom sheet with a peripheral edge with at least one exhaust opening therein, the bottom sheet having opposite top and bottom surfaces, the bottom sheet top surface having at least one pocket, the at least one pocket being dimensioned and adapted to receive the at least one air distribution member and enclose the base bottom side and a portion of the base top side of the at least one air distribution member;
• and a selectively operable air pump for selectively supplying an air flow to the at least one air distribution member, the air flow flowing across the air distribution member between the air distribution member top side and the cushion bottom surface and upwardly through the cushion apertures to a selected moisture vapor drying zone.

A moisture drying mattress comprising:

• at least one cushion having opposite top and bottom surfaces and a plurality of apertures extending through the cushion from the bottom surface to the top surface;
• a plurality of air channel mats, each air channel mat having a base and being dimensioned and adapted to fit beneath the at least one cushion and support the at least one cushion bottom surface in a spaced relation from the base, each said air channel mat defining a vapor drying zone;
• a cover encasing said at least one cushion and plurality of air channel mats creating a vapor drying space below the cover at each vapor drying zone for evaporation of moisture vapor by a flow of air within the vapor drying space, said cover being pervious to surface moisture vapor to allow moisture vapor into the vapor drying space and impermeable to liquid to prevent liquid from outside the cover from entering the mattress and also impermeable to the flow of air within the vapor drying space to prevent the flow of air within the vapor drying space from passing through the cover;
• and
• a selectively operable air pump for selectively supplying an air flow to the plurality of air channel mats, the air flow supplied to the mats flowing over the mats between the base and the cushion bottom surface and upwardly through the cushion apertures to remove moisture vapor by the flow of air in the vapor drying space.

A vapor drying mattress comprising:

• at least one cushion;
• a cover over said at least one cushion, said cover having a top and a bottom, said top having an outer layer and an inner layer laminated to said top layer, said cover being impermeable to fluid but permeable to moisture vapor;
• at least one pocket at the inner layer of the cover top;
• an air diffuser positioned in the at least one pocket, said pocket and air diffuser defining a moisture drying zone below said cover;
• an air pump operatively connected to the at least one pocket for selectively supplying an air flow to the air diffuser, the air flow supplied to the air diffuser flowing through the air diffuser toward the moisture drying zone to remove moisture vapor by a flow of air in the moisture drying zone.
