Abstract

According to certain arrangements, a conditioner mat for use with a bed assembly includes an upper layer comprising a plurality of openings, a lower layer being substantially fluid impermeable, at least one interior chamber defined by the upper layer and the lower layer and a spacer material positioned within the interior chamber. In one embodiment, the spacer material is configured to maintain a shape of the interior chamber and to help with the passage of fluids within a portion of interior chamber. The conditioner mat can be configured to releasably secure to a top of a bed assembly.

First claim

What is claimed is:

1. A topper member for use with a medical bed, the topper member comprising:
an enclosure defining at least one fluidly-distinct interior chamber and having substantially fluid impermeable upper and lower layers; said upper layer comprising a plurality of openings through which fluid from the at least one fluidly-distinct interior chamber can exit; said upper and lower layers attached along at least a part of a periphery of the topper member to form a periphery fluid boundary along the at least a part of the periphery of the topper member;
at least one securement device for at least temporarily securing the topper member to a medical bed;
at least one spacer material positioned within the at least one fluidly-distinct interior chamber, said at least one spacer material configured to maintain a desired separation between the upper and lower layers and to help distribute fluid within the at least one fluidly-distinct interior chamber;
at least one fluid module comprising a fluid transfer device;
a conduit placing an outlet of the at least one fluid module in fluid communication with the at least one fluidly-distinct interior chamber;
wherein the fluid module selectively delivers fluids to the at least one fluidly-distinct interior chamber through the conduit;
wherein fluids entering the at least one fluidly-distinct interior chamber are generally distributed within said at least one fluidly-distinct interior chamber by the at least one spacer material before exiting through the plurality of openings along the upper layer;
wherein the upper and lower layers are attached to each other at least partially away from the periphery of the topper member to form at least one internal fluid boundary at a location where the upper and lower layers are attached, wherein the at least one internal fluid boundary is at least partially spaced apart from the periphery fluid boundary of the periphery of the topper member; and
wherein the at least one internal fluid boundary at least partially defines at least one non-fluid zone adjacent the at least one fluidly-distinct interior chamber, the at least one non-fluid zone comprising at least one fluid impermeable member, wherein said at least one fluid impermeable member is configured to generally prevent fluid flow through the at least one non-fluid zone.

2. The topper member of claim 1 , wherein the enclosure defines a first fluidly-distinct chamber and at least a second fluidly-distinct chamber, said first fluidly-distinct chamber being configured to receive fluid having a first temperature from a first fluid module, and said second fluidly-distinct chamber being configured to receive fluid having a second temperature from a second fluid module, wherein the first temperature is greater than the second temperature.

3. The topper member of claim 1 , wherein the internal fluid boundary at least partially divides the fluidly-distinct interior chamber.

4. The topper member of claim 3 , wherein the at least one internal fluid boundary divides the at least one fluidly-distinct interior chamber into a first fluidly-distinct chamber and at least a second fluidly-distinct chamber.

5. The topper member of claim 4 , wherein the first fluidly-distinct chamber and the at least a second fluidly-distinct chamber are formed from a monolithic material of the upper layer at least across the at least one internal fluid boundary and a monolithic material of the lower layer at least across the at least one internal fluid boundary.

6. The topper member of claim 4 , wherein the at least one internal fluid boundary substantially inhibits fluid to pass between the first fluidly-distinct chamber and the at least a second fluidly-distinct chamber.

7. The topper member of claim 4 , wherein the at least one internal fluid boundary Hall extends between a portion of the periphery of the topper member at least partially defining the first fluidly-distinct chamber and a portion of the periphery of the topper member at least partially defining the at least a second fluidly-distinct chamber.

8. The topper member of claim 1 , wherein the at least one internal fluid boundary extends between a first side and a second side of the periphery of the topper member, and wherein the at least one internal fluid boundary is at least partially spaced apart from a third side and a fourth side of the periphery of the topper member.

9. A method of reducing the likelihood or preventing bed sores to an occupant of a bed, the method comprising:
providing a topper member, said topper member comprising:
an enclosure defining at least one fluidly-distinct interior chamber and having substantially fluid impermeable upper and lower layers; the upper and lower layers attached along at least a part of a periphery of the topper member to form a periphery fluid boundary along the at least a part of the periphery of the topper member; the upper and lower layers attached to each other at least partially away from the periphery of the topper member to form at least one internal fluid boundary at a location where the upper and lower layers are attached, the at least one internal fluid boundary at least partially spaced apart from the periphery fluid boundary of the periphery of the topper member, said upper layer comprising a plurality of openings through which fluid from the at least one fluidly-distinct interior chamber can exit;
at least one securement device for at least temporarily securing the topper member to a bed;
a spacer material positioned within the at least one fluidly-distinct interior chamber, said spacer material configured to maintain a desired separation between the upper and lower layers and to help distribute fluid within the at least one fluidly-distinct interior chamber;
at least one fluid module comprising a fluid transfer device;
a conduit placing an outlet of the at least one fluid module in fluid communication with the at least one fluidly-distinct interior chamber;
wherein the fluid module selectively delivers fluids to the at least one fluidly-distinct interior chamber through the conduit;
wherein fluids entering the at least one fluidly-distinct interior chamber are generally distributed within said chamber by the spacer material before exiting through the plurality of openings along the upper layer; and
wherein the at least one internal fluid boundary at least partially defines at least one non-fluid zone adjacent the at least one fluidly-distinct interior chamber, the at least one non-fluid zone comprising at least one fluid impermeable member, wherein said at least one fluid impermeable member is configured to generally prevent fluid flow through the at least one non-fluid zone;

positioning the topper member on a mattress or support pad of a bed;
securing the topper member to the mattress or support pad; and
activating the at least one fluid module to selectively transfer fluids to a bed occupant through the at least one fluidly-distinct interior chamber.

10. The method of claim 9 , further comprising removing the topper member from the mattress or support pad for cleaning or replacing said topper member.

11. The method of claim 10 , wherein cleaning the topper member comprises cleaning exterior surfaces of the upper and lower layers.

12. The method of claim 9 , wherein the at least one internal fluid boundary divides the at least one fluidly-distinct interior chamber into a first fluidly-distinct chamber and at least a second fluidly-distinct chamber, and further comprising transferring fluids to at least one of the first fluidly-distinct chamber and the at least a second fluidly-distinct chamber via the at least one fluid module.
