Optionally, each of the plurality of fill valves 29 comprises a built-in muffler to reduce the noise of air entering into the inflatable chamber 14 and a removable air filter to purify the air entering into the inflatable chamber 14
In reference to FIG. 4 and FIG. 8, the dump valve 25 is connected to the rear panel 16 so that the inflatable chamber 14 can be quickly deflated. More specifically, the dump valve 25 allows the user or the care giver to either manually control the inside pressure of the inflatable chamber 14 or to deflate the inflatable chamber 14. A preferred embodiment of the dump valve 25 comprises a stationary plate, a plurality of stationary holes, a rotary plate, a plurality of rotary holes, an outside knob, and an inside knob as shown in FIG. 10. The stationary plate is connected to the rear panel 16, and the plurality of stationary holes is radially positioned on the stationary plate. Each of the plurality of stationary holes has a different diameter, where each of the plurality of stationary holes differs from one another. The rotary plate is rotatably connected with the stationary plate, where the rotary plate is adjacently positioned with the stationary plate from outside of the rear panel 16. The plurality of rotary holes is radially positioned on the rotary plate. Each of the plurality of rotary holes has a different diameter, where each of the plurality of rotary holes differs from one another. Since each of the plurality of stationary holes and each of the plurality of rotary holes have different diameters, The plurality of stationary holes and the plurality of rotary holes are positioned in the order of increasing size, such that a small hole is adjacent to a medium hole, the medium hole is in between the small hole and a large hole, and the large hole is adjacent to the medium hole. The outside knob is concentrically connected with the rotary plate and allows the care giver standing outside of the inflatable chamber 14 to manually control inside pressure. The inside knob is concentrically traversed through the stationary plate and connected with the rotary plate in such way that the inside knob is oppositely positioned from the outside knob. The inside knob allows the user within the inflatable chamber 14 to manually control the inside pressure without exiting the inflatable chamber 14.
In reference to a preferred operation of the dump valve 25, the dump valve 25 is operated by turning the outside knob or the inside knob which turns the rotary plate, changing the alignment of the plurality of rotary holes with respect to the plurality of stationary holes. As shown in FIG. 11-A, when none of the plurality of rotary holes is aligned with the plurality of stationary holes, the dump valve 25 is completely sealed and the pressure inside the inflatable remains constant. As shown in FIG. 11-D, when all of the plurality of rotary holes is aligned with the plurality of stationary holes, the dump valve 25 is working at its full capacity. In reference to FIG. 11-B, 11-C, 11-E, and 11-F, by only aligning some of the plurality of rotary holes with the plurality of stationary holes, the dump valve 25 can be used to adjust the rate of depressurization. In reference to FIG. 11-F, the first example that aligns some of the plurality of rotary holes with the plurality of stationary holes shows that the large hole of the plurality of stationary holes is aligned with the small hole of the plurality of rotary holes, letting out a small amount of air, since the small hole of the plurality of rotary holes bottlenecks the large hole of the plurality of stationary holes. In reference to FIG. 11-E, the second example that aligns some of the plurality of rotary holes with the plurality of stationary holes shows The large hole and the medium hole of the plurality of stationary holes are aligned with the medium hole and the small hole of the plurality of rotary holes, which would release a larger amount of air. These two sample configurations allow some depressurization to occur, but not as much when compared to having all of the plurality of rotary holes align with the plurality of stationary holes.

The first relief valve 31 is connected to the rear panel 16. The second relief valve 32 is connected to the door panel 17. The first relief valve 31 and the second relief valve 32 are activated at a lower pressure of the inflatable chamber 14 so that the present invention can maintain an operating pressure within the inflatable chamber 14. More specifically, the first relief valve 31 and the second relief valve 32 automatically open once the inflatable chamber 14 is fully pressurized the operating pressure wherein the lower pressure is equal to the operating pressure. Preferably, the lower pressure of the inflatable chamber 14 is at 4.4 psi to provide a comfortable and safe environment for the user. Furthermore, the first relief valve 31 and the second relief valve 32 allow the circulation of fresh air within the inflatable chamber 14 and the expulsion of carbon-dioxide out of the inflatable chamber 14 while maintaining the constant operating pressure within the present invention. In other words, when the first relief valve 31 and the second relief valve 32 are opened, circulated air within the inflatable chamber 14 exits through the present invention and allow fresh air to enter into the inflatable chamber 14 through the plurality of fill valves 29. Due to the fact lower hoop stress is applied to the door panel 17 and the rear panel 16 in comparison to the lateral panel 15, the structural integrity of the first relief valve 31 and the second relief valve 32 can be further improved within the present invention.
In reference to FIG. 3-4, the at least one secondary pressure relief valve 28 comprises a third relief valve 33 and a fourth relief valve 34. The third relief valve 33 is connected to the rear panel 16. The fourth relief valve 34 is connected to the door panel 17. The third relief valve 33 and the fourth relief valve 34 are activated at a higher pressure of the inflatable chamber 14 so that the present invention can maintain a safe operating pressure within the inflatable chamber 14. More specifically, the third relief valve 33 and the fourth relief valve 34 automatically open when in the inside pressure of the inflatable chamber 14 continue to rise beyond the operating pressure, wherein the higher pressure is equal to the safe operating pressure. Preferably, the higher pressure of the inflatable chamber 14 is at 4.6 psi to provide a safe environment for the user without compromising the integrity of the present invention. Furthermore, the third relief valve 33 and the fourth relief valve 34 allow the circulation of fresh air within the inflatable chamber 14 and the expulsion of carbon-dioxide out of the inflatable chamber 14 while maintaining the safe operating pressure within the present invention. In other words, when the third relief valve 33 and the fourth relief valve 34 are opened, circulated air within the inflatable chamber 14 exits through the present invention and allow fresh air to enter into the inflatable chamber 14 through the plurality of fill valves 29. Due to the fact lower hoop stress is applied to the door panel 17 and the rear panel 16 in comparison to the lateral panel 15, the structural integrity of the third relief valve 33 and the fourth relief valve 34 can be further improved within the present invention.
In reference to FIG. 4, the present invention further comprises a plurality of auxiliary ports 26. More specifically, the plurality of auxiliary ports 26 is connected to the rear panel 16 in such way that the plurality of auxiliary ports 26 traverses through the rear panel 16. The plurality of auxiliary ports 26 is in fluid communication with the inflatable chamber 14 so that optional medical equipment such as oxygen suppling system or gas sampling system can be operatively coupled with the present invention.
The present invention can further comprise a stretcher attachment. More specifically, a preferred embodiment of the stretcher attachment comprises a L-shaped support bracket and an extended plank attached to the L-shaped support bracket. The extended plank is of a flat, quadrilateral-like shaped figure to facilitate for easier transportation of individuals and objects in and out of the inflatable chamber 14.
The present invention can further comprise an inflatable seat so that the user can sit within the inflatable chamber 14. It is preferred that the inflatable seat be pre-inflated at set pressure value higher than the pressure value of the inflatable chamber 14.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
