Description
Technical Field
[0001] The invention relates to the technical field of oxygen chambers, in particular to a buoyancy-pressurized hyperbaric oxygen chamber. Background Art
[0002] The oxygen chamber is a special medical device for high-pressure oxygen therapy. Its principle is to place the user in an oxygen-rich environment with a pressure higher than normal atmospheric pressure. Under the action of high pressure, oxygen is input into the respiratory and microcirculatory systems and reaches various organs of the human body, increasing the level of arterial oxygen partial pressure and oxygen saturation to promote human metabolism. Treatment in a high-pressure oxygen chamber is generally combined with pure oxygen inhalation therapy.
[0003] At present, the commonly used method of pressurizing a hyperbaric oxygen chamber is to use an air compressor to provide high-pressure air for filling and pressurization. This method has the disadvantages of high noise and high energy consumption. In addition, the hyperbaric oxygen chamber is generally placed in the air. Since the temperature inside the chamber will rise during the pressurization process, it will generally cause the temperature inside the chamber to be too high when used indoors. However, the air conditioning cooling method will increase the noise and occupy the space inside the chamber due to the fan installed in the chamber, so the user experience is poor.

[0012] 1. The present invention uses the design of the water tank and the pressurized chamber to achieve precise control of the pressure in the chamber by using the up and down movement of the buoyancy sealing plate.

DETAILED DESCRIPTION
[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0023] Example 1
[0024] A buoyancy-pressurized hyperbaric oxygen chamber, such as Figures 1 to 5 As shown, it includes a mounting platform 1, a water tank 14 is provided at the upper end of the mounting platform 1, a cabin 3 extending to the top of the water tank 14 is provided on one side thereof, a hatch 6 is provided on the top of the cabin 3, and the hatch 6 is an inwardly opening type, an oxygen concentrator 8 is provided on the upper surface of the water tank 14 near the cabin 3, an oxygen supply pipe 7 of an oxygen mask 2 in the cabin 3 is connected to the oxygen concentrator 8, and an oxygen exhaust pipe 4 extends out of the cabin 3;
[0025] The water tank 14 on one side away from the cabin 3 extends downward out of the mounting platform 1, and a pressurizing chamber 20 is provided on the other side of the water tank 14. A monitoring pipeline extending from the top of the water tank 14 is connected to the top of the pressurizing chamber 20, and a pressure gauge 10 is connected to the monitoring pipeline, so that the pressure in the cabin can be monitored in real time. A plurality of support columns 18 are respectively provided at the bottom of the cabin 3 and the pressurizing chamber 20, and the cabin 3 and the pressurizing chamber 20 are respectively fixedly connected to the water tank 14 through the support columns 18. The top of the pressurizing chamber 20 is connected to the oxygen cabin through a connecting pipe 9, and a water inlet hole is provided at the bottom of the pressurizing chamber 20, and the water inlet hole and the support column 18 at the bottom are arranged alternately. A buoyancy sealing plate 15 is provided in the pressurizing chamber 20 for sliding sealing, and three pairs of O-rings are sleeved around the buoyancy sealing plate 15, which can be sealed with the pressurizing chamber 20 to achieve sealing around the pressurizing chamber 20, so that the buoyancy sealing plate 15 can be moved upward by the thrust of the water flow at its lower end. A water inlet pipe 11 is connected to one side of the upper end of the water tank 14, and a water inlet solenoid valve 13 is provided on the water inlet pipe 11. A drain pipe 17 is connected to one side of the bottom of the water tank 14, and a drain solenoid valve 16 is provided on the drain pipe 17. An exhaust pipe 12 is connected to the upper end of one side of the water tank 14.
[0026] Ladders 5 are provided on the outer wall of the water tank 14 near one side of the cabin body 3 and inside the cabin body 3, respectively, so as to facilitate users to enter the oxygen cabin.
[0027] When the present invention is installed, the water tank 14 extending below the installation platform 1 is partially buried in the foundation pit, the installation platform 1 is installed at the ground level, and the upper part of the oxygen cabin and the water tank 14 is located above the ground level. When in use, the user enters the oxygen cabin through the ladder 5 and wears the oxygen mask 2. The oxygen mask 2 forms a sealed cavity with the user's mouth and nose and is isolated from the cabin space. The oxygen generator 8 is turned on to provide oxygen to the user. At this time, external personnel are required to close the cabin door 6 and open the water inlet solenoid valve 13. Water is added to the water tank 14 through the water inlet pipe 11. At this time, the drainage solenoid valve 16 is in a closed state, and the water level at the bottom of the water tank 14 gradually rises. The water flows into the interior of the pressurized chamber 20 through the through hole 19 at the bottom. The rising water level pushes the buoyancy sealing plate 15 to float up. As the water level rises, it can be seen from the water pressure calculation formula P=ρgh that the upward water pressure on the buoyancy sealing plate 15 gradually increases, and the gas is continuously squeezed through the connecting pipe 9 into the cabin body 3. When the buoyancy sealing plate 15 is subjected to the upward pressure, the gas is continuously squeezed through the connecting pipe 9 into the cabin body 3. When the buoyancy on the upper side is greater than the sum of its gravity and the air pressure of the upper space, the buoyancy sealing plate 15 moves upward. As the buoyancy sealing plate 15 gradually moves, the upper space gradually decreases, and the pressure in the pressurized chamber 20 and the cabin gradually increases. As the amount of water injected increases, when the water level in the water tank 14 is higher than the upper exhaust pipe 12, water begins to flow out of the exhaust pipe 12. At this time, the water inlet solenoid valve 13 is closed to stop the water inlet into the water tank 14. The water level is maintained at the highest point. At this time, most of the outer wall of the cabin 3 is immersed in water. The material of the oxygen cabin is generally metal, and the heat conduction performance is good, so the temperature of the water can be transferred to the inside of the oxygen cabin. When the temperature is high in summer, the water inlet temperature can be lowered, and the temperature of the cold water is transferred to the inside of the oxygen cabin. Even without using air conditioning, the cabin temperature can be kept suitable, thereby improving the user experience. At this time, the buoyancy of the buoyancy sealing plate 15 is balanced with the sum of its gravity and the air pressure of the upper space, and the cabin is in a stable high-pressure state, and the user can perform stable high-pressure treatment. When the treatment is completed, the bottom drainage solenoid valve 16 is opened to drain the water. As the water level drops, the pressure in the cabin also drops. When the pressure in the cabin drops to atmospheric pressure, the cabin door 6 can be opened and the patient can leave the cabin to complete the treatment.
[0028] Specifically, in this embodiment, the oxygen cabin is a cylinder, the inner diameter of the cabin body 3 is 1m, and the height is 2m, then the volume of the oxygen cabin is about V=πr2h=3.14*12*2=6.28m3, the pressurized chamber 20 is also a cylinder with a radius of 2m, then the end surface area of the buoyancy sealing plate 15 is about S=πr2=3.14*22=12.56m2, if you want to pressurize the pressure in the oxygen cabin to two atmospheres, that is, about 100Kpa, you only need to raise the sealing buoyancy plate 15 by 0.5m. If the buoyancy sealing plate 15 is in a stable state after being raised by 0.5m from the lowest point, the weight of the buoyancy sealing plate 15 itself is about 100kg, then its gravity is about 1000 N, even a pressure difference of 1Kpa exerts a pressure of 12560N on the buoyancy sealing plate 15, which is much greater than its own gravity. The upward pressure exerted by the buoyancy on the buoyancy sealing plate 15 is approximately equal to the pressure in the oxygen chamber, that is, the water pressure on the buoyancy sealing plate 15 is approximately 100Kpa. According to the water pressure formula P=ρgh, h=10m can be obtained. That is, if the maximum treatment pressure of the oxygen chamber is designed to be 100Kpa, the height difference between the lowest point of the buoyancy sealing plate 15 and the highest point of the liquid surface is 10.5m. In actual use, the water adding height is adjusted according to the value displayed on the pressure gauge 10. According to different heights of the liquid surface, the treatment pressure in the oxygen chamber can be between 0 and 100Kpa.
[0029] The present invention increases pressure by means of buoyancy. When the water level is stable at the highest point, the water level difference is constant. After the upper and lower pressures of the buoyancy sealing plate are balanced, the pressure in the cabin is stable, and the pressure stabilization treatment effect is better. In addition, since the pressurization is performed by water intake, there is no stable noise from the air compressor, and when the water wraps the oxygen cabin, the noise in the oxygen cabin is less affected by the outside world, a low-noise environment can be created, and the user experience can be improved. Moreover, the water temperature can be adjusted to adjust the temperature in the cabin by heat transfer, so that the cabin can be kept at a suitable temperature condition, and the use effect is better.
