Abstract

A self-adjusting, non-powered smart response technology mattress generally includes an accelerated calibration system comprising a valve fluidly connected to a body support device including a plurality of fluid support cells, wherein each fluid support cell includes an envelope and a reforming element disposed within the envelope; and a non-powered manifold system including a manifold conduit interconnecting at least two of the fluid support cells, and intake and exhaust valves fluidly coupled to the manifold conduit configured to dynamically open and close in response to a weight load. The accelerated calibration system is configured to selectively permit fluid flow out of the fluid support cells in the absence of a weight load upon opening of the valve. Also discloses is a process for releasing excess pressure formed as a result of temperature and barometric pressure changes in the self-adjusting, non-powered smart response technology mattress.

First claim

What is claimed is:

1. A self-adjusting, non-powered smart response technology mattress comprising:
a body support device comprising:
a plurality of fluid support cells, wherein each fluid support cell includes an envelope and a reforming element disposed within the envelope to provide the envelope with an original form;
a non-powered manifold system including a manifold conduit interconnecting at least two of the fluid support cells, and intake and exhaust pressure relief valves fluidly coupled to the manifold conduit configured to dynamically open and close at respective pressure ratings for the intake and exhaust pressure relief valve to self-adjust pressure in response to a weight load; and
an accelerated calibration system free of a pumping mechanism comprising a valve fluidly connected to the manifold conduit and configured to bypass the intake and exhaust pressure relief valves, wherein the valve of the accelerated calibration system is configured to selectively permit fluid flow from the fluid support cells in the absence of a weight load upon opening of the valve and in response to a change in barometric pressure that inflates the original form; and

one or more layers overlaying the body support device and a side rail assembly circumscribing a perimeter of the body support device, wherein the smart response technology mattress is free of a powered pump.

2. The mattress of claim 1 , wherein the valve fluidly connected to the manifold conduit comprises a conduit having a proximal end in fluid communication with the manifold conduit and a distal end having an opening in fluid communication with an external environment, wherein the valve is coupled to the distal end conduit to selectively permit fluid flow to the external environment.

3. The mattress of claim 1 , wherein the reforming element is a foam body and is encapsulated in an envelope.

4. The mattress of claim 1 , wherein the valve is coupled to a spring loaded button.

5. The mattress of claim 1 , wherein the reforming element is a coil encased in a foam body.

6. The mattress of claim 1 , wherein the reforming element is a bellows.

7. The mattress of claim 1 , wherein the fluid in the fluid support cells is air.

8. The mattress of claim 1 , wherein the side rail assembly includes an access opening, and the valve is recessed within the side rail assembly.

9. A process for releasing excess pressure formed as a result of barometric pressure changes in a self-adjusting, non-powered smart response technology (SRT) mattress, the process comprising:
providing the SRT mattress with an accelerated calibration system free of a pumping mechanism comprising a valve fluidly connected to a manifold conduit interconnecting a plurality of fluid support cells, wherein each fluid support cell includes an envelope and a reforming element disposed within the envelope, wherein the manifold conduit includes intake and exhaust pressure relief valves configured to dynamically open and close in response to a weight load, and wherein the accelerated calibration system is configured to bypass the intake and exhaust pressure relief valves; and
opening the valve in fluid communication with an external environment and the manifold conduit in the absence of an applied load and in response to a change in barometric pressure that inflates the envelope.

10. The process of claim 9 , wherein opening the valve comprises pushing a spring loaded button fluidly coupled to a conduit in fluid communication with the manifold conduit.
