DETAIL DESCRIPTIONS OF THE INVENTION

(11) All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

(12) The present invention is a system for cooling a hyperbaric chamber which comprises a compressor 1, a first hose 2, a cooling unit 3, a second hose 4, and a hyperbaric chamber 5. In reference to FIG. 1, the compressor 1 is fluidly connected with the cooling unit 3 by the first hose 2, and the cooling unit 3 is fluidly connected with the hyperbaric chamber 5 by the second hose 4.

(13) The compressor 1 used within the present invention can be any type of air compressor 1 which is able to compress or pressurize air so that the cooling unit 3 and the hyperbaric chamber 5 can be pressurized according to system requirements. Since the compression of the air generates heat; compressed air from the compressor 1 outputs warm air compare to the ambient temperature. The compressor 1 comprises a male compressed air outlet, where the male compressed air outlet outputs the warm compressed air for the cooling unit 3 and the hyperbaric chamber 5.

(14) In reference to FIG. 2 and FIG. 3, the first hose 2 and the second hose 4 each comprises a male attachment opening 21 and a female attachment opening 22. The male attachment opening 21 and the female attachment opening 22 are oppositely positioned from each other along the first hose 2 and the second hose 4. The first hose 2 and the second hose 4 are preferably made from flexible medical grade polyvinyl chloride (PVC) or any other type of flexible biocompatible materials as the first hose 2 connects in between the compressor 1 and the cooling unit 3, and the second hose 4 connects in between the cooling unit 3 and the hyperbaric chamber 5.

(15) In reference to FIG. 4, the cooling unit 3 comprises a male attachment inlet 31, a first pressure relief fitting 32, and a female attachment outlet 33. The cooling unit 3 is a sealed enclosure with two openings, where the two openings are the male attachment inlet 31 and the female attachment outlet 33. The cooling unit 3 has a flexible shell and preferably made into a cylindrical shape. In a preferred embodiment of the present invention, the cooling unit 3 has a length of 24 inches and a diameter of 10 inches, but the size of the cooling unit 3 can be increased or decreased depending on the hyperbaric chamber 5. The first pressure relief fitting 32 is fluidly connected with the cooling unit 3 from one end, and the male attachment inlet 31 is fluidly connected with the first pressure relief fitting 32. As show in FIG. 7, the male attachment opening 21 of the first hose 2 is fluidly connected with the female compressed air outlet of the compressor 1, and the female attachment opening 22 of the first hose 2 is fluidly connected with the male attachment inlet 31, where the first hose 2 is able to transport the warm compressed air from the compressor 1 to the male attachment inlet 31. Then the warm compressed air travels from the male attachment inlet 31 to the first pressure relief fitting 32 which depressurizes the warm compressed air. For example, if the compressor 1 generates 15 pounds per square inch (psi) compressed air, the first pressure relief fitting 32 converts the 15 psi compressed air into 8 psi compressed air. When the warm compressed air is depressurized from the first pressure relief fitting 32 and released into the cooling unit 3, the warm compressed air expands within the cooling unit 3. The expansion of the warm compressed air absorbs some of the generated heat, converting the warm compressed air into cool compressed air within the cooling unit 3. As a result, the cool compressed air leaves the cooling unit 3 at a lower temperature and a lower pressure than it has when generated at the compressor 1. The female attachment outlet 33 is fluidly connected with the cooling unit 3 and positioned oppositely from the male attachment inlet 31. The male attachment opening 21 of the second hose 4 is fluidly connected with the female attachment outlet 33 so that the cooling unit 3 can be connected with the hyperbaric chamber 5 through the second hose 4.

(16) The cooling unit 3 of the present invention completely eliminates existing cooling methods such as the chillers and chlorofluorocarbon based coolers and their respective disadvantages. The chillers normally create condensation and mold problems over time while the chlorofluorocarbon based coolers are hazardous for certain individuals and environment. Since the cooling unit 3 does not use any ice or chlorofluorocarbon to reduce the temperature of the compressed air, condensation problems, mold problems, and high maintenance cost don't occur within the cooling unit 3 of the present invention. The passive nature of the cooling unit 3 of the present invention also reduces the complexity compared to existing cooling methods, where the reduced complexity results into corresponding decrease in cost and maintenance. The cooling unit 3 also does not require any additional energy source to operate within the present invention.

(17) In reference to FIG. 5, the hyperbaric chamber 5 comprises an inlet male attachment 51, a second pressure relief fitting 52, a dump valve 53, an access opening 54, and at least one auxiliary valve 55. The hyperbaric chamber 5 is a pressurized vessel which creates a controlled environment so that patients can rest during the medical treatments. The hyperbaric chamber 5 is preferably made into a cylindrical shape, but is not limited only to the cylindrical shape and can be any other geometrical shapes. The access opening 54 is positioned along the hyperbaric chamber 5 and provides an opening so that the patients can move in and out of the hyperbaric chamber 5. The access opening 54 is hermetically sealed by a fastening mechanism during the operation of the present invention so that the pressurized air can be withheld within the hyperbaric chamber 5. For safety purposes, the fastening mechanism can be opened or closed from inside of the hyperbaric chamber 5 or the outside of the hyperbaric chamber 5. The second pressure relief fitting 52 is fluidly connected with the hyperbaric chamber 5, and the inlet male attachment 51 is fluidly connected with the second pressure relief fitting 52. As shown in FIG. 7, the female attachment opening 22 of the second hose 4 is fluidly connected with the inlet male attachment 51, where the second hose 4 is able to transport the cool compressed air from the cooling unit 3 to the inlet male attachment 51. Then the cool compressed air travels from the inlet male attachment 51 to the second pressure relief fitting 52 which further depressurizes the cool compressed air within the present invention. For example, if the cool compressed air is depressurized up to 8 psi within the cooling unit 3, the second pressure relief fitting 52 converts the 8 psi compressed air into 4 psi compressed air. When the cool compressed air is depressurized from the second pressure relief fitting 52 and released into the hyperbaric chamber 5, the cool compressed air expands within the hyperbaric chamber 5. The expansion of the cool compressed air absorbs some of the heat within, converting the cool compressed air into cooler compressed air within the hyperbaric chamber 5. The second pressure relief fitting 52 brings down the pressure of the cool compressed air from the cooling unit 3 into the desired pressure of the hyperbaric chamber 5 so that the hyperbaric chamber 5 can be pressurized into the desired pressure with the comfortable temperature setting. As a result of the pressure reduction in the first pressure relief fitting 32 and the second pressure relief fitting 52 along with the cooling unit 3, the temperature of the compressed air inside the hyperbaric chamber 5 of the present invention is significantly cooler compare to a hyperbaric chamber with a direct compressor connection. The first pressure relief fitting 32 and the second pressure relief fitting 52 can also be replace with depressurizing nozzles within the present invention as long as the depressurizing nozzles can bring down the pressure of the compressed air.

(18) The dump valve 53 is fluidly connected with the hyperbaric chamber 5, where the dump valve 53 allows the patients or a responsible individual to control the inside pressure of the hyperbaric chamber 5. In reference to FIG. 6, the dump valve 53 comprises a stationary plate 61, a plurality of stationary holes 62, a rotary plate 63, a plurality of rotary holes 64, an outside knob 65, and an inside knob 66. The stationary plate 61 is connected with the hyperbaric chamber 5, and the plurality of stationary holes 62 is radially positioned on the stationary plate 61. Each of the plurality of stationary holes 62 has a different diameter, where each of the plurality of stationary holes 62 differs from one another. The rotary plate 63 is rotatably connected with the stationary plate 61, where the rotary plate 63 is adjacently positioned with the stationary plate 61 from outside of the hyperbaric chamber 5. The plurality of rotary holes 64 is radially positioned on the rotary plate 63. Each of the plurality of rotary holes 64 has a different diameter, where each of the plurality of rotary holes 64 differs from one another. Since each of the plurality of stationary holes 62 and each of the plurality of rotary holes 64 have different diameter, The plurality of stationary holes 62 and the plurality of rotary holes 64 are positioned in 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 65 is concentrically connected with the rotary plate 63 which allows the individuals standing outside of the hyperbaric chamber 5 to control inside pressure of the hyperbaric chamber 5. The inside knob 66 is concentrically traversed through the stationary plate 61 and connected with the rotary plate 63 in such way that the inside knob 66 is oppositely positioned from the outside knob 65. The inside knob 66 allows a patient within the hyperbaric chamber 5 to control the inside pressure of the hyperbaric chamber 5 without leaving the hyperbaric chamber 5.

(19) The dump valve 53 is operated by turning the outside knob 65 or the inside knob 66 which turns the rotary plate 63, changing the alignment of the plurality of rotary holes 64 with respect to the plurality of stationary holes 62. In reference to FIG. 8, when none of the plurality of rotary holes 64 is aligned with the plurality of stationary holes 62, the dump valve 53 is completely sealed and the pressure inside the hyperbaric chamber 5 remains constant. In reference to FIG. 10, when all of the plurality of rotary holes 64 is aligned with the plurality of stationary holes 62, the dump valve 53 is working at its full capacity. As shown in FIG. 9, by only aligning some of the plurality of rotary holes 64 with the plurality of stationary holes 62, the dump valve 53 can be used to adjust the rate of depressurization. For example, the large hole of the plurality of stationary holes 62 can be aligned with the small hole of the plurality of rotary holes 64, letting out a small amount of air, since the small hole of the plurality of rotary holes 64 bottlenecks the large hole of the plurality of stationary holes 62. Or the large hole and the medium hole of the plurality of stationary holes 62 can be aligned with the medium hole and the small hole of the plurality of rotary holes 64, 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 64 align with the plurality of stationary holes 62. In reference to FIG. 7, the at least one auxiliary valve 55 is fluidly connected with the hyperbaric chamber 5.

(20) The cooling unit 3 acts as a muffler when the compressed air travels through the cooling unit 3 and damps the sound waves from the compressor 1. The cooling unit 3 isolates noises from the compressor 1, specifically the motor, as well as reducing sound from the air. Since the cooling unit 3 is passive, it has a net reduction on noise levels compare to the existing cooling methods. Reduction of the sound level within the present invention creates a comfortable and quiet environment within the hyperbaric chamber 5 for the patient.

(21) 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.
