Abstract

A person-support surface comprises a non powered mattress and a coverlet positionable on the non powered mattress. The coverlet includes an entry positioned at a first end of the coverlet, an exit positioned at a second end of the coverlet opposite the entry, an upper air impermeable layer, and a lower air impermeable layer coupled to the upper air impermeable layer to form an air flow path along the coverlet between the entry and the exit. The upper air impermeable layer is a vapor permeable and the lower air impermeable layer is a vapor permeable.

First claim

What is claimed is:

1. A fluid supply system, comprising:
a gas blower; and
a conduit coupled to the gas blower and configured to communicate gas therethrough, the conduit including a connector configured to be repeatedly coupled to a medical device, the gas blower configured to be activated when the conduit is coupled to the medical device and deactivated when the conduit is decoupled from the medical device, wherein the connector comprises a plurality of conductive elements that, when the connector is coupled to the medical device, are electrically connected to activate the gas blower.

2. The fluid supply system of claim 1 , wherein the gas blower is positioned under a foot section of a bed frame.

3. The fluid supply system of claim 1 , wherein the gas blower is included in a mattress replacement system.

4. The fluid supply system of claim 1 , wherein the medical device is a temperature and moisture regulating coverlet.

5. The fluid supply system of claim 4 , wherein the gas blower cooperates with the temperature and moisture regulating coverlet to maintain at least one of a surface temperature of at least a portion of a surface of the coverlet between about 90° F. and about 95.5° F., a relative humidity of at least a portion of a surface of the coverlet between about 55% relative humidity and about 95% relative humidity, and a heat withdrawal capacity of at least a portion of a surface of the coverlet between about 60 W/m 2 and about 125 W/m 2 .

6. The fluid supply system of claim 1 , wherein the medical device is a powered mattress including a gas bladder.

7. The fluid supply system of claim 1 , wherein the medical device is a therapy garment.
