  • the top layer 44 and the bottom layer 46 are both configured to be vapor permeable and air impermeable. This configuration prevents air passing through the coverlet from impinging on the skin of a person positioned on the coverlet 26 while allowing the moisture produced by the person to pass through the top layer 44 and be exhausted with the air passing through the coverlet out the outlet 50.
  • the 3-dimensionally engineered spacer 52 is positioned in the inner chamber 54 and is configured to be air and moisture permeable as shown in Figs. 2-5 .
  • the 3-dimensionally engineered spacer 52 is configured to maintain a path for the air to flow through when a person is supported on the coverlet 26.
  • the 3-dimensionally engineered spacer 52 is Spacenet ® .
  • the inlet 48 and the outlet 50 are generally located on opposite ends of the coverlet 26 and allow a fluid, such as, air, to be communicated into the inner chamber 54 of the coverlet 26, and to be exhausted from the coverlet 26, respectively, as shown in Figs. 2-5 .
  • the inlet 48 is located along the second section S1 of the coverlet 26 and the outlet 50 is located along the first section F1 of the coverlet 26.
  • the inlet 48 includes an inlet connector 56 configured to couple to and receive fluid from the fluid supply assembly 16 as shown in Fig. 6 .
  • the fluid supply 16 and coverlet 26 can cooperate to maintain at least one of a surface temperature, a relative surface humidity, and a heat withdrawal capacity of at least a portion of the surface which is in contact, directly or indirectly, with the person within a predefined range, for example, between about 90 oF and about 95.5 oF; between about 55% relative humidity and about 95% relative humidity; and/or between about 60 W/m 2 and about 125 W/m 2 , as disclosed in, U.S. Patent Application Serial No. 12/937,306 .
  • the fluid supply assembly 16 includes a fluid supply 58 enclosed within a housing 60, a controller 62, and a conduit 64 as shown in Figs. 6-8 .
  • the fluid supply 58 is an air blower and the housing 60 is coupled to the underside of the second section S1 of the upper frame 22.
  • the housing 60 is integrated into a footboard (not shown) coupled to the person-support apparatus 12.
  • the controller 62 is configured to control the operation of the fluid supply 58.
  • the controller 62 activates and/or deactivates the fluid supply 58 when the conduit 64 is coupled/uncoupled to/from the coverlet 26.
  • the controller 62 can also cause the fluid supply 58 to supply fluid at a predetermined rate and/or adjust the temperature and humidity of the fluid supplied by the fluid supply 58.
  • the controller 62 can activate/deactivate the fluid supply 58 when the conduit 64 is coupled/uncoupled to/from a therapy device, powered mattress, or other pneumatic device or instrument.
  • the conduit 64 is configured to facilitate communication of fluid between the fluid supply 58 and the coverlet 26 as shown in Fig. 6 .
  • the conduit 64 is configured to be coupled to an outlet (not shown) of the fluid supply 58 and configured to be removably coupled to the inlet connector 56.
  • the conduit 64 includes a conduit connector 66 with a fluid outlet port 68 and a connection sensor 70 as shown in Fig. 8 .
  • the connection sensor 70 is configured to sense when the conduit connector 66 is coupled to the inlet connector 56.
  • the connection sensor 70 is a pair of conductive strips configured to engage a conductive strip (not shown) on the inlet connector 56 that electrically connects the pair conductive strips to complete the circuit. This embodiment would not necessarily require a controller to activate/deactivate the fluid supply 58.
  • the sensor 70 is a switch (not shown).
  • the conduit connector 66 is not connected from the inlet connector 56.
  • the user connects the conduit connector 66 to the inlet connector 56.
