Description

Technical Field

[0001] This application relates to the technical field of hyperbaric oxygen therapy, and in particular to an Internet of Things-based hyperbaric oxygen therapy monitoring system. Background Technology

[0002] Hyperbaric oxygen therapy is a medical treatment that promotes tissue healing and recovery by having patients inhale pure oxygen in a hyperbaric environment. In hyperbaric oxygen therapy, patients are placed in a hyperbaric chamber with an oxygen concentration higher than atmospheric pressure, usually in a pure oxygen environment or a pressurized air environment. When patients are in a high oxygen concentration and high pressure environment, the pure oxygen they inhale leads to an increase in the amount of dissolved oxygen in their blood.

[0003] These oxygen molecules are more easily transported to various tissues and organs in the body, thereby increasing the oxygen supply to hypoxic tissues. By increasing oxygen delivery, hyperbaric oxygen therapy can accelerate wound healing and promote tissue repair. This is because oxygen is essential for human cells to carry out metabolism, and a sufficient oxygen supply can help cells more effectively perform energy production and repair work.

[0004] Hyperbaric oxygen therapy helps improve blood oxygen levels and promotes the repair and regeneration of damaged tissues. This treatment method is widely used clinically in various conditions, such as burns, necrotic soft tissue infections, radiation injuries, and carbon monoxide poisoning. Furthermore, hyperbaric oxygen therapy is also used to treat other diseases, such as the medical hyperbaric oxygen chamber oxygen mask with a dynamic oxygen monitoring system (publication number CN106139352A), which relates to the field of medical hyperbaric oxygen chamber oxygen mask technology. In this prior art, the mask has an oxygen inhalation connector on the spherical side and an exhalation connector below. A buckle-fixed disc has oxygen inhalation and exhalation sleeves that fit around the oxygen inhalation and exhalation connectors. The oxygen inhalation connector connects to a curved tube, a dynamic oxygen monitoring system, a filter, a three-way valve, and an oxygen source connector; the third-way valve connects to a humidifier; and the exhalation connector connects to an exhaust hose. This invention designs the upper and lower oxygen inhalation and exhalation connectors according to the specific gravity of oxygen to carbon dioxide. Its colored luminous floats are bright, eye-catching, intuitive, and dynamically float up and down. The structural design is novel, practical, scientific, and reasonable.

[0005] However, the aforementioned existing technologies still have some shortcomings when it comes to hyperbaric oxygen therapy: 1. The oxygen inhalation connector and exhalation connector on the existing mask are located at opposite ends of the mask, one at the top and one at the bottom. This allows the lighter oxygen to enter from the top of the mask, while the heavier carbon dioxide exhaled by the patient is expelled from the bottom of the mask, effectively utilizing oxygen. However, during actual hyperbaric oxygen therapy, prolonged exposure to a high concentration of oxygen may lead to oxygen poisoning in patients, resulting in damage to the central nervous system and organs such as the lungs.

[0006] 2. Depending on the type and severity of the patient's disease, different treatment cycles may be required. Some acute diseases may only require short-term treatment, while some chronic diseases may require longer-term continuous treatment. During long-term continuous treatment, the existing technology mentioned above requires wearing an oxygen mask for an extended period of time, which may cause discomfort to the patient, including the risk of ear pain or tympanic membrane rupture, skin allergies, facial pressure, and other problems. In addition, some patients may experience anxiety reactions to the high-oxygen environment, affecting the comfort and compliance of treatment.

[0007] 3. In the aforementioned existing technology, when hyperbaric oxygen therapy is performed using a mask, oxygen within the mask may be lost during the patient's breathing intervals, resulting in oxygen waste. Therefore, based on the above points, there is still room for improvement in the existing technology for hyperbaric oxygen therapy. Summary of the Invention

[0008] To address the aforementioned technical problems, this application provides an IoT-based hyperbaric oxygen therapy monitoring system, employing the following technical solution: A hyperbaric oxygen therapy monitoring system based on the Internet of Things includes a treatment chamber, a sealed door on one side of the treatment chamber, an oxygen generator on one side of the treatment chamber, a gas mixer connected to the oxygen generator on one side of the treatment chamber, a carbon dioxide filter connected to the oxygen generator on one side of the treatment chamber, and an air circulator on the treatment chamber. The air circulator includes a sealing cover installed on the treatment chamber, a reciprocating screw is rotatably installed inside the sealing cover, and a sealing plate is slidably installed inside the sealing cover and threadedly connected to the reciprocating screw.

[0009] Preferably, the air circulator further includes an air inlet chamber and an air outlet chamber separated by a sealing plate inside a sealing cover. At least one one-way valve one and one one-way valve two are respectively provided on opposite sides of the air inlet chamber and the air outlet chamber, and one one-way valve one and one one-way valve two are arranged in opposite directions. The gas mixer is provided with an air inlet pipe that extends into the air inlet chamber, and a one-way air inlet valve is provided inside the air inlet pipe. The carbon dioxide filter is provided with an air outlet pipe that extends into the air outlet chamber, and a one-way air outlet valve is provided inside the air outlet pipe.

[0010] Preferably, a pressure controller is provided on one side of the treatment chamber; The pressure controller includes a sealing tube passing through one side of the treatment chamber, a connecting tube connected to a carbon dioxide filter on the sealing tube, a sealing plug slidably disposed inside the sealing tube, and an adjusting rod rotatably disposed on the sealing plug that slides through the sealing tube. A support plate is slidably disposed inside the sealing tube and slidably connected to the adjusting rod. An adjusting screw threadedly connected to the sealing tube is rotatably disposed on the support plate. A support spring is disposed between the support plate and the sealing plug.

[0011] Preferably, the adjusting rod is provided with a threaded section that is threaded to the sealing pipe.

[0012] Preferably, a shuttle is provided on one side of the treatment chamber; The shuttle includes a treatment chamber located on one side of a sealed door, and the shuttle chamber is equipped with a shuttle door.

[0013] Preferably, both the shuttle cabin and the treatment cabin are provided with connecting pipes, and one end of the two connecting pipes is connected to an adjusting pipe. A cylinder is provided on one side of the adjusting pipe, and an adjusting sealing plate connected to the telescopic end of the cylinder is slidably provided inside the adjusting pipe.

[0014] Preferably, the treatment chamber is equipped with an oxygen inhaler; The oxygen inhaler includes an oxygen supply pipe and an exhaust pipe that pass through the treatment chamber via a bracket. One end of the oxygen supply pipe passes through the treatment chamber and is connected to an oxygen generator, and one end of the exhaust pipe passes through the treatment chamber and is connected to a carbon dioxide filter. Several oxygen inhalation components located inside the treatment chamber are provided on the oxygen supply pipe and the exhaust pipe.

[0015] Preferably, the oxygen inhalation device includes an oxygen inhalation mask, which is provided with a first telescopic hose and a second telescopic hose. Each of the ends of the first telescopic hose and the second telescopic hose facing the oxygen inhalation mask is provided with a check valve. The ends of the first telescopic hose and the second telescopic hose away from the oxygen inhalation mask are respectively connected to an oxygen delivery pipe and an exhaust pipe.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. When a patient requires hyperbaric oxygen therapy, the gas mixer mixes the oxygen generated by the oxygen generator with other gases to adjust the oxygen concentration. The gas mixer then delivers the mixed gas into the treatment chamber. Through the gas mixer, the oxygen concentration in the treatment chamber can be precisely controlled to ensure that the patient receives an appropriate ratio of oxygen to other gases. As the gas mixer continuously delivers the mixed gas into the treatment chamber, air pressure is created inside the chamber. The patient can then breathe freely within the treatment chamber. The increased air pressure helps improve oxygen delivery and absorption, making it easier for oxygen to enter the bloodstream. This can help reduce swelling or inflammation in some body tissues, or alleviate conditions such as hypoxia and carbon monoxide poisoning at high altitudes.

[0017] 2. When a patient requires hyperbaric oxygen therapy, medical staff can adjust the air pressure using a pressure controller according to the patient's condition and treatment needs. The pressure controller changes the elasticity of the spring; the elasticity of the supporting spring determines the pressure required inside the treatment chamber to push the sealing plug, compressing the supporting spring and thus changing the pressure inside the treatment chamber. This ensures the safety and effectiveness of the treatment and avoids the danger to the patient caused by excessively high or low air pressure.

[0018] 3. During the treatment of a patient, the present invention allows the patient to enter and exit the treatment chamber via a shuttle, enabling patients who have finished their treatment to leave and patients who arrive from outside to enter. At the same time, when the patient is receiving hyperbaric oxygen therapy in the treatment chamber, they can breathe freely according to their condition, or breathe higher purity oxygen through the oxygen inhalation device in the treatment chamber.

[0030] The following is in conjunction with the appendix Figures 1 to 11 This application will be described in further detail.

[0031] This application discloses an IoT-based hyperbaric oxygen therapy monitoring system. When a patient needs hyperbaric oxygen therapy, the system allows the patient to breathe freely. The increased air pressure improves oxygen delivery and absorption, making it easier for oxygen to enter the bloodstream. This helps reduce swelling or inflammation in some body tissues, or alleviate conditions such as hypoxia and carbon monoxide poisoning at high altitudes. Example 1: Reference Figure 1 and Figure 2 A hyperbaric oxygen therapy monitoring system based on the Internet of Things includes a treatment chamber 1. When a patient needs hyperbaric oxygen therapy, a sealed door 11 on one side of the treatment chamber 1 is first opened, allowing the patient to pass through the sealed door 11 into the treatment chamber 1. The patient then sits on one of the seats 2 provided on either side of the treatment chamber 1 for resting. Figure 9 (As shown in the middle) Then close the sealing door 11 to create a sealed environment inside the treatment chamber 1.

[0032] Then, the oxygen generator 3 installed on one side of the treatment chamber 1 is activated. The oxygen generator 3 absorbs outside air to produce oxygen. At the same time, the gas mixer 4 installed on one side of the treatment chamber 1 and connected to the oxygen generator 3 is activated. The gas mixer 4 mixes the oxygen produced by the oxygen generator 3 with other gases to adjust the oxygen concentration to meet specific treatment needs. Then, the gas mixer 4 delivers the mixed gas into the treatment chamber 1. The gas mixer 4 can precisely control the oxygen concentration in the treatment chamber 1 to ensure that the patient receives an appropriate ratio of oxygen to other gases.

[0033] As the gas mixer 4 continuously supplies mixed gas into the treatment chamber 1, it creates air pressure inside the treatment chamber 1. Medical staff can adjust the air pressure according to the patient's condition and treatment needs through the pressure controller 7 set on one side of the treatment chamber 1 to ensure the safety and effectiveness of the treatment and avoid the danger to the patient caused by excessively high or low air pressure. Patients can breathe freely in treatment chamber 1. The increased air pressure can help improve oxygen delivery and absorption, making it easier for oxygen to enter the bloodstream. This can help reduce swelling or inflammation in some body tissues, or alleviate conditions such as hypoxia and carbon monoxide poisoning at high altitudes.

[0034] As the patient breathes continuously, the oxygen in treatment chamber 1 is consumed and carbon dioxide is expelled. Therefore, after the pressure in treatment chamber 1 stabilizes, the air circulator 6 installed on treatment chamber 1 is activated. The air circulator 6 extracts the gas from treatment chamber 1 and delivers it to the carbon dioxide filter 5 installed on one side of treatment chamber 1. The carbon dioxide filter removes the carbon dioxide from the gas. Then, it is connected to the oxygen generator 3 to deliver the filtered gas to the oxygen generator 3. The oxygen generator 3 absorbs the filtered gas and outside air to produce oxygen, which is then delivered back to the gas mixer 4 for mixing. The gas mixer 4 then delivers the mixed gas back into treatment chamber 1 through the air circulator 6, thereby replenishing the extracted gas and forming a circulation, ensuring that the gas in treatment chamber 1 is sufficient and clean.

[0035] Reference Figure 3 and Figure 4 Specifically, the air circulator 6 includes a sealing cover 61 installed on the treatment chamber 1. A reciprocating screw 62 is rotatably installed inside the sealing cover 61. After the pressure inside the treatment chamber 1 stabilizes, a drive motor 63 connected to the reciprocating screw 62 and installed on one side of the sealing cover 61 is activated. The drive motor 63 drives the reciprocating screw 62 to rotate. The rotating reciprocating screw 62 drives the sealing plate 64 that is slidably installed inside the sealing cover 61 through a threaded connection. That is, the sealing plate 64 is slidably installed inside the sealing cover 61 and threadedly connected to the reciprocating screw 62, so that the sealing plate 64 moves back and forth continuously within the sealing frame as the reciprocating screw 62 rotates.

[0036] The sealed cover 61 is divided into an air inlet chamber 65 and an air outlet chamber 66 by a sealing plate 64. The gas mixer 4 is provided with an air inlet pipe 67 that penetrates into the air inlet chamber 65, while the carbon dioxide filter 5 is provided with an air outlet pipe 68 that penetrates into the air outlet chamber 66.

[0037] During the reciprocating guidance process of the sealing plate 64, when the sealing plate 64 moves towards the air intake chamber 65, the space inside the air intake chamber 65 is compressed and becomes smaller. At this time, the mixed oxygen in the air intake chamber 65 cannot pass through the one-way air intake valve 671 set in the air intake pipe 67, but will pass through the one-way valve 651 on the side of the air intake chamber 65 away from the air outlet chamber 66, and thus enter the treatment chamber 1. At the same time, as the space inside the air outlet chamber 66 expands as the air intake chamber 65 shrinks, the mixed oxygen in the gas mixer 4 cannot pass through the one-way air outlet valve 681 set in the air outlet pipe 68, while the gas breathed by the patient in the treatment chamber 1 will pass through the one-way valve 661 on the side of the air outlet chamber 66 away from the air intake chamber 65 and enter the air outlet chamber 66.

[0038] In other words, at least one one-way valve 651 and one one-way valve 661 are respectively provided on opposite sides of the air intake chamber 65 and the air outlet chamber 66, and the one one-way valve 651 and one one-way valve 661 are arranged in opposite directions.

[0039] Conversely, when the sealing plate 64 moves towards the exhaust chamber 66, the space inside the exhaust chamber 66 is compressed and becomes smaller. At this time, the gas breathed by the patient in the intake chamber 65 cannot pass through the one-way valve 661, but will pass through the one-way exhaust valve 681 set in the exhaust pipe 68 and enter the carbon dioxide filter 5 for filtration. At the same time, as the space inside the intake chamber 65 expands as the exhaust chamber 66 shrinks, the gas breathed by the patient in the treatment chamber 1 cannot enter the intake chamber 65, while the oxygen mixed in the gas mixer 4 will pass through the one-way intake valve 671 and enter the intake chamber 65 to replenish the oxygen in the intake chamber 65.

[0040] Through the design of one inlet and one outlet, the system removes the gas breathed by the patient while replenishing an equal amount of oxygen, achieving a cycle of oxygen replenishment and carbon dioxide removal, thus improving treatment effectiveness and safety. While maintaining the pressure inside treatment chamber 1, it also ensures that the patient receives a sufficient oxygen supply during treatment.

[0041] When the gas mixer 4 is started, it continuously supplies mixed gas into the treatment chamber 1. At this time, the air circulator 6 has not yet started. The mixed gas in the gas mixer 4 passes through the one-way air inlet valve 671 in the air inlet pipe 67, enters the air inlet chamber 65, and then passes through the one-way valve 651 into the treatment chamber 1. When the pressure in the treatment chamber 1 reaches the preset value, the gas mixer 4 begins to maintain the pressure.

[0042] Reference Figure 5 and Figure 6Specifically, the pressure controller 7 includes a sealing tube 71 that passes through one side of the treatment chamber 1. When the gas mixer 4 delivers mixed gas into the treatment chamber 1, as the air pressure in the treatment chamber increases, the air pressure will push the sealing plug 73 that is slidably disposed inside the sealing tube 71, and drive the adjusting rod 74 that is rotatably disposed on the sealing plug 73 and passes through the sealing tube 71. A support plate 75 that is slidably disposed inside the sealing tube 71 and slidably connected to the adjusting rod 74 will be pushed. The pushed sealing plug 73 will compress the support spring 77 disposed between the support plate 75 and the sealing plug 73.

[0043] When the sealing plug 73 moves to the connecting pipe 72 on the sealing tube 71, the gas in the treatment chamber 1 will enter the carbon dioxide filter 5 connected to it through the connecting pipe 72, causing the air pressure in the treatment chamber 1 to drop. As the air pressure in the treatment chamber 1 drops, the compressed support spring 77 will push the sealing plug 73 to move, blocking the sealing tube 71, preventing the air pressure in the treatment chamber 1 from being discharged through the connecting pipe 72, thereby ensuring that the pressure in the treatment chamber 1 is within a certain range, and ensuring that the air pressure in the treatment chamber 1 is within a safe range during the patient's treatment.

[0044] When it is necessary to adjust the air pressure inside the treatment chamber 1, the adjusting screw 76, which is rotatably connected to the sealing pipe 71 on the support plate 75, is rotated to increase the compression force of the support spring 77 or decrease the release force of the support spring 77, thereby changing the force of the support spring 77. The force of the support spring 77 determines how much pressure is needed inside the treatment chamber 1 to push the sealing plug 73 and compress the support spring 77, thereby changing the pressure inside the treatment chamber 1.

[0045] After treatment, turn off the drive motor 63, oxygen generator 3, gas mixer 4, and gas mixer 4. Then pull the adjusting rod 74 to connect the threaded section 78 on the adjusting rod 74 to the sealing rod, so that the sealing tube 71 is always open. The gas in the treatment chamber is discharged from the connecting tube 72 to balance the air pressure in the treatment chamber 1 with the outside air pressure. Then open the sealing door 11 to let the patient leave.

[0046] Example 2: Refer to Figure 8 and Figure 9 Based on Example 1, Since different patients have different treatment times, and there is inconvenience if a patient needs to leave or if a patient outside needs to enter the treatment chamber 1, a shuttle 8 is installed on one side of the treatment chamber 1. The shuttle 8 is used for patients who have finished treatment to leave and for patients outside who need to enter.

[0047] Specifically, the shuttle 8 includes a treatment chamber 1 and a shuttle cabin 81 located on one side of the sealed door 11. Both the shuttle cabin 81 and the treatment chamber 1 are equipped with connecting pipes 83. One end of the two connecting pipes 83 is connected to an adjusting pipe 84. When the outside needs to enter the treatment chamber 1 that is in operation, first ensure that the sealed door 11 is closed, then open the shuttle door 82 set on the shuttle cabin 81, then let the patient who needs to enter enter the shuttle cabin 81, and then close the shuttle door 82.

[0048] Then, the cylinder 85 on one side of the regulating pipe 84 is activated. The cylinder 85 pulls the regulating sealing plate 86, which is slidably installed inside the regulating pipe 84 and connected to the telescopic end of the cylinder 85, so that the two connecting pipes 83 are connected through the regulating pipe 84. At this time, the gas in the treatment chamber 1 will enter the shuttle chamber 81 through the connecting pipe 83. After the gas pressure in the treatment chamber 1 and the shuttle chamber 81 is balanced, the sealing door 11 is opened, and the gas enters the treatment chamber 1 through the sealing door 11 and then the sealing door 11 is closed. At this time, the cylinder 85 is pushed out and drives the regulating sealing plate 86, so that the two connecting pipes 83 are no longer connected.

[0049] When a patient leaves after completing treatment inside the treatment chamber, first ensure that the shuttle door 82 is closed, then open the sealing door 11, pass through the sealing door 11 into the shuttle chamber 81, and then close the sealing door 11 again. Activate the cylinder 85 to pull the adjusting plate 86, so that the two connecting pipes 83 are connected through the adjusting pipe 84, allowing the gas in the treatment chamber 1 to enter the shuttle chamber 81 through the connecting pipe 83. Once the air pressure in the treatment chamber 1 and the shuttle chamber 81 is balanced, then open the sealing door 11 again, pass through the sealing door 11 into the shuttle chamber 81, and then close the sealing door 11. Then, push out the cylinder 85 and drive the adjusting plate 86 to disconnect the two connecting pipes 83.

[0050] Then, the shuttle cabin 81 is depressurized. After the depressurization is completed, ensure that the sealing door 11 is closed before opening the shuttle door 82, and then allow the patient who needs to leave to leave through the shuttle door 82.

[0051] During this process, the gas in the treatment chamber 1 will enter the shuttle chamber 81 through the connecting pipe 83, which will cause the air pressure in the treatment chamber 1 to drop. In order to ensure that the air pressure in the treatment chamber 1 is within a certain range, the gas mixer 4 enters the shuttle chamber 81 along with the gas in the treatment chamber 1, and simultaneously replenishes the treatment chamber 1 with mixed oxygen to ensure that the air pressure in the treatment chamber 1 does not drop, and at the same time replenishes and balances the air pressure in the shuttle chamber 81.

[0052] Seats 2 are also provided on both sides of the shuttle cabin 81 so that patients can sit down and rest while waiting for the air pressure in the treatment cabin 1 and the shuttle cabin 81 to equalize.

[0053] Example 3: Refer to Figure 9 , Figure 10 and Figure 11Based on Examples 1 and 2, When patients breathe oxygen freely in treatment chamber 1, because each person needs a different concentration of oxygen, treatment chamber 1 is equipped with an oxygen concentrator 9; the oxygen concentrator 9 is used for patients to breathe oxygen with higher purity in treatment chamber 1.

[0054] Specifically, the oxygen concentrator 9 includes an oxygen supply tube 91 and an exhaust tube 92 that are inserted into the treatment chamber 1 through a bracket. When the patient is undergoing hyperbaric oxygen therapy in the treatment chamber 1, he / she can breathe freely according to his / her condition, or breathe oxygen with higher purity through several oxygen inhalation components 93 located in the treatment chamber 1 on the oxygen supply tube 91 and the exhaust tube 92.

[0055] During oxygen therapy, when a patient inhales using the oxygen inhalation device 93, oxygen is drawn from the oxygen delivery tube 91. Since one end of the oxygen delivery tube 91 passes through the treatment chamber 1 and is connected to the oxygen generator 3, the oxygen in the oxygen delivery tube 91 has a higher purity. When a patient exhales using the oxygen inhalation device 93, the exhaled gas enters the exhaust tube 92. Since one end of the exhaust tube 92 passes through the treatment chamber 1 and is connected to the carbon dioxide filter 5, the patient's exhaled waste gas enters the carbon dioxide filter 5. The carbon dioxide filter 5 filters the carbon dioxide in the patient's exhaled waste gas and then sends it back to the oxygen generator 3 for oxygen production.

[0056] The oxygen inhalation component 93 includes an oxygen inhalation mask 931, on which a first telescopic hose 932 and a second telescopic hose 933 are provided. Each of the ends of the first telescopic hose 932 and the second telescopic hose 933 facing the oxygen inhalation mask 931 is provided with a check valve 934. The ends of the first telescopic hose 932 and the second telescopic hose 933 away from the oxygen inhalation mask 931 are respectively connected to an oxygen delivery pipe 91 and an exhaust pipe 92.

[0057] When a patient is using oxygen therapy, they first put on the oxygen mask 931. When the patient exhales through the oxygen mask 931, the gas in the discharge tube 92 cannot pass through the check valve 934 in the second telescopic hose 933. Instead, the oxygen in the delivery tube 91 passes through the first telescopic hose 932, then through the check valve 934 in the first telescopic hose 932, and then into the oxygen mask 931, allowing the patient to breathe oxygen. When the patient exhales through the oxygen mask 931, the exhaled waste gas cannot pass through the check valve 934 in the first telescopic hose 932 into the delivery tube 91. Instead, it passes through the check valve 934 in the second telescopic hose 933 into the discharge tube 92.

[0058] Meanwhile, even if the oxygen mask leaks, the oxygen inhaled or entering the treatment chamber 1 will be filtered by the air circulator 6 and will not affect other patients.

[0059] The oxygen supply pipe 91 and the discharge pipe 92 extend into the shuttle cabin 81 and are also equipped with oxygen inhalation devices 93. When the patient enters the shuttle cabin 81, during the process of equalizing the air pressure in the treatment cabin 1 and the shuttle cabin 81, an oxygen mask can be used to inhale oxygen.

[0060] The implementation principle of this invention is as follows: (1): When a patient needs hyperbaric oxygen therapy, first open the sealed door 11 to let the patient enter the treatment chamber 1, and then close the sealed door 11 to create a sealed environment inside the treatment chamber 1.

[0061] (2): Then start the oxygen generator 3 and the gas mixer 4. The gas mixer 4 will mix the oxygen generated by the oxygen generator 3 with other gases to adjust the oxygen concentration. Then the gas mixer 4 will deliver the mixed gas into the treatment chamber 1. Through the gas mixer 4, the oxygen concentration in the treatment chamber 1 can be precisely controlled to ensure that the patient receives an appropriate ratio of oxygen and other gas mixture.

[0062] (3): As the gas mixer 4 continuously delivers mixed gas into the treatment chamber 1, it creates air pressure inside the treatment chamber 1. Medical staff can adjust the air pressure through the pressure controller 7 according to the patient's condition and treatment needs. The pressure controller 7 changes the elasticity of the spring; and the elasticity of the support spring 77 determines how much pressure is needed inside the treatment chamber 1 to push the sealing plug 73, compressing the support spring 77, thereby changing the pressure inside the treatment chamber 1 to ensure the safety and effectiveness of the treatment and avoid the danger to the patient caused by excessively high or low air pressure. (4): Then the patient breathes freely in treatment chamber 1. The increased air pressure can help improve the delivery and absorption of oxygen, making it easier for oxygen to enter the blood, which is beneficial to reduce swelling or inflammation of some body tissues, or hypoxia and carbon monoxide poisoning in high-altitude environments.

[0063] (5): As the patient continues to breathe, the oxygen in the treatment chamber 1 will be consumed and carbon dioxide will be discharged. Therefore, after the pressure in the treatment chamber 1 stabilizes, the air circulator 6 installed on the treatment chamber 1 is activated. The air circulator 6, through its one-in-one-out design, draws out the gas breathed by the patient and replenishes an equal amount of oxygen, thereby achieving the circulation and replenishment of oxygen and the removal of carbon dioxide, improving the treatment effect and safety. While ensuring the pressure in the treatment chamber 1, it also ensures that the patient receives a sufficient oxygen supply during the treatment process.

[0064] (6): The gas extracted by the air circulation will be transported to the carbon dioxide filter 5 set on one side of the treatment chamber 1. The carbon dioxide filter will filter out the carbon dioxide in the gas. Then, the filtered gas will be transported to the oxygen generator 3 through the connection with the oxygen generator 3. The oxygen generator 3 will absorb the filtered gas and the outside air to produce oxygen, and then transport it back to the gas mixer 4 for mixing. Then, the gas mixer 4 will transport the mixed gas into the treatment chamber 1 through the air circulator 6, thereby filling the extracted gas to form a circulation and ensuring that the gas in the treatment chamber 1 is sufficient and clean.

Claims

1. A hyperbaric oxygen therapy monitoring system based on the Internet of Things, comprising a treatment chamber (1), a sealed door (11) provided on one side of the treatment chamber (1), an oxygen generator (3) provided on one side of the treatment chamber (1), a gas mixer (4) connected to the oxygen generator (3) provided on one side of the treatment chamber (1), and a carbon dioxide filter (5) connected to the oxygen generator (3) provided on one side of the treatment chamber (1), characterized in that: An air circulator (6) is installed on the upper part of the treatment chamber (1). The air circulator (6) includes a sealing cover (61) provided on the treatment chamber (1), a reciprocating screw (62) is rotatably provided inside the sealing cover (61), and a sealing plate (64) threadedly connected to the reciprocating screw (62) is slidably provided inside the sealing cover (61). The air circulator (6) further includes a sealing cover (61) which is divided into an air inlet chamber (65) and an air outlet chamber (66) by a sealing plate (64). At least one one-way valve one (651) and one one-way valve two (661) are respectively provided on opposite sides of the air inlet chamber (65) and the air outlet chamber (66), and the one one-way valve one (651) and the one one-way valve two (661) are arranged in opposite directions. The gas mixer (4) is provided with an air inlet pipe (67) that extends into the air inlet chamber (65), and a one-way air inlet valve (671) is provided in the air inlet pipe (67). The carbon dioxide filter (5) is provided with an air outlet pipe (68) that extends into the air outlet chamber (66), and a one-way air outlet valve (681) is provided in the air outlet pipe (68). During the reciprocating guidance of the sealing plate (64), when the sealing plate (64) moves towards the air inlet chamber (65), the space inside the air inlet chamber (65) will be compressed and become smaller. At this time, the mixed oxygen in the air inlet chamber (65) cannot pass through the one-way air inlet valve (671) set in the air inlet pipe (67), but will pass through the one-way valve one (651) on the side of the air inlet chamber (65) away from the air outlet chamber (66), and thus enter the treatment chamber (1). At the same time, as the space inside the air outlet chamber (66) expands as the air inlet chamber (65) shrinks, the mixed oxygen in the gas mixer (4) cannot pass through the one-way air outlet valve (681) set in the air outlet pipe (68), and the gas breathed by the patient in the treatment chamber (1) will pass through the one-way valve two (661) set in the side of the air outlet chamber (66) away from the air inlet chamber (65) and enter the air outlet chamber (66). Conversely, when the sealing plate (64) moves toward the outlet chamber (66), the space inside the outlet chamber (66) is compressed and becomes smaller. At this time, the gas in the inlet chamber (65) that has been breathed by the patient cannot pass through the one-way valve (661), but will pass through the one-way outlet valve (681) set in the outlet pipe (68) and enter the carbon dioxide filter (5) for filtration. At the same time, as the space inside the inlet chamber (65) expands as the outlet chamber (66) shrinks, the gas in the treatment chamber (1) that has been breathed by the patient cannot enter the inlet chamber (65), while the oxygen mixed in the gas mixer (4) will pass through the one-way inlet valve (671) and enter the inlet chamber (65) to replenish the oxygen in the inlet chamber (65).

2. The hyperbaric oxygen therapy monitoring system based on the Internet of Things according to claim 1, characterized in that: A pressure controller (7) is provided on one side of the treatment chamber (1); The pressure controller (7) includes a sealing tube (71) passing through one side of the treatment chamber (1), a connecting tube (72) connected to the carbon dioxide filter (5) is provided on the sealing tube (71), a sealing plug (73) is slidably provided inside the sealing tube (71), and an adjusting rod (74) that slides through the sealing tube (71) is rotatably provided on the sealing plug (73).
