Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a multi-buffer energy-saving hyperbaric oxygen chamber adopting mechanical self-compensation sealing. Background Art

[0002] A hyperbaric oxygen chamber is a closed device that can provide a pure oxygen or oxygen-rich gas environment with a pressure higher than one atmosphere. It significantly increases the amount of oxygen inhaled by the human body by increasing the oxygen partial pressure in the environment, thereby achieving the purpose of treating diseases or promoting recovery.

[0003] At present, most hyperbaric oxygen chambers adopt a single buffer chamber design. The buffer chamber is mainly used for pressure transition when patients enter and exit the large oxygen chamber, so as to complete the entry and exit operations without affecting the internal pressure of the large oxygen chamber. However, this design has many disadvantages: First, the flexibility is poor. During the treatment process, patients need to enter the large oxygen chamber on time. Once they miss the start time of treatment, they will not be able to participate, resulting in reduced efficiency in the use of the oxygen chamber; second, there is serious waste of energy. If the large oxygen chamber adjusts the pressure for patients entering and leaving the chamber, the pressure increase and decompression operations in the entire chamber will consume a lot of energy; third, it is not very convenient to use. If a patient needs to leave the chamber in advance, it may interfere with the treatment of other patients and increase the complexity of the operation. Therefore, the present invention provides a multi-buffer energy-saving hyperbaric oxygen chamber with a mechanical self-compensating seal to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a multi-buffer energy-saving hyperbaric oxygen chamber with mechanical self-compensating seal. By setting a large oxygen chamber and multiple small oxygen chambers, independent pressurization and decompression control systems can be provided in the multiple small oxygen chambers. The large oxygen chamber is pressurized only once at the beginning of treatment, and then a stable pressure is maintained. The patient enters and exits through the small oxygen chamber, which reduces the number of pressurization or decompression times of the large chamber, and reduces operating costs and energy consumption. In addition, the large oxygen chamber and the small oxygen chamber are relatively independent of the pressurization system, so the patient can enter and exit the large oxygen chamber through the small oxygen chamber at any time, and it will not affect the patients who are already receiving treatment, reducing the waiting time for patients waiting for treatment, and meeting the multi-user processing needs in emergency situations. The above settings can solve the problems of energy loss, inconvenience in use and poor flexibility.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A multi-buffered energy-saving hyperbaric oxygen chamber adopting mechanical self-compensating seal comprises a large oxygen chamber and a sealing assembly, wherein at least two first passages are fixedly connected to the outer wall of the large oxygen chamber, a small oxygen chamber is fixedly connected to one end of the first passage, and a second passage is fixedly connected to the outer wall of the small oxygen chamber; the sealing assembly is used to seal the hyperbaric oxygen chamber, and the sealing assembly is respectively connected to the first passage and the second passage.

[0007] Optionally, the sealing assembly includes a first door frame and a second door frame, and the first door frame and the second door frame are respectively installed in the middle of the first aisle and at one end of the second aisle.

[0010] Optionally, the second frame and the third frame are fixedly connected to the outer walls on both sides of the first frame, respectively, one end of the second frame is fixedly connected to a C-shaped elastic plate, one end of the C-shaped elastic plate is fixedly connected to an L-shaped frame, and several segmented grooves are opened on the outer walls of the C-shaped elastic plate and the L-shaped frame.

[0011] Optionally, a first cylinder is fixedly connected to the top outer wall of the second passage, a second cylinder is fixedly connected to the top outer wall of the first cylinder, and a scale is provided on the outer wall of the second cylinder.

[0012] Optionally, a first piston plate is slidably connected to the inner wall of the first cylinder, a spring is fixedly connected to the top outer wall of the first piston plate, a support column is fixedly connected to the top outer wall of the first piston plate, and one end of the support column is fixedly connected to the second piston plate.

[0013] Optionally, the third cylinder, the fourth cylinder and the first oil pipeline are installed on the outer wall of the second cylinder, and the second oil pipeline is fixedly connected to the top outer wall of the second cylinder.

[0014] Optionally, one end of the third cylinder away from the second cylinder is screwed with a first threaded column, and one end of the fourth cylinder away from the second cylinder is screwed with a second threaded column.

[0015] Optionally, one end of the first threaded column away from the fourth cylinder is fixedly connected to the first anti-slip handle, and the other end of the first threaded column is fixedly connected to the third piston plate, and one end of the second threaded column away from the fourth cylinder is fixedly connected to the second anti-slip handle, and the other end of the second threaded column is fixedly connected to the fourth piston plate.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up a large oxygen chamber and multiple small oxygen chambers, independent pressurization and decompression control systems can be equipped in multiple small oxygen chambers. The large oxygen chamber only performs a pressurization operation once at the beginning of treatment, and then maintains a stable pressure. Patients enter and exit the small oxygen chamber, reducing the number of pressurization or decompression times of the large chamber, reducing operating costs and energy consumption. In addition, the large oxygen chamber and the small oxygen chamber are relatively independent of the pressurization system, so patients can enter and exit the large oxygen chamber through the small oxygen chamber at any time, and it will not affect patients who are already receiving treatment, reducing the waiting time for patients waiting for treatment, and meeting the multi-user processing needs in emergency situations.

[0018] By setting up the sealing assembly, not only can the hyperbaric oxygen chamber be sealed to ensure stable air pressure in the chamber and avoid energy loss, but it can also provide a self-compensation effect after the seal ring is worn. In addition, when the seal ring is damaged, it is convenient for the operator to remove the seal ring.

[0019] By arranging the first frame, the arc-shaped elastic plate, the second frame, the third frame, the C-shaped elastic plate and the L-shaped frame in the sealing assembly, not only can the sealing ring be shaped, but it can also adapt to the contour of the cabin door to improve the sealing effect of the cabin door. In addition, when the sealing ring is severely worn, it is convenient for maintenance personnel to replace the new sealing ring, saving costs.

[0020] By arranging the first cylinder, the second cylinder, the first piston plate, the spring and the second piston plate in the sealing assembly, the second piston plate can be pushed to move by pressurizing the small oxygen chamber, thereby pushing out the sealing liquid in the second cylinder. This design has a simple structure and does not require additional energy to push the second piston plate, thus avoiding energy loss.

[0021] By arranging the third cylinder, the fourth cylinder, the first threaded column, the second threaded column, the third piston plate and the fourth piston plate in the sealing assembly, not only can the cabin door be sealed by pressurizing the small oxygen cabin, but also the sealing ring can be provided with a self-compensation effect after the sealing ring is worn.

[0043] like Figures 1 to 12 As shown, an embodiment of the present invention provides a multi-buffer energy-saving hyperbaric oxygen chamber using mechanical self-compensating sealing, including a large oxygen chamber 1, at least two first aisles 101 are fixedly connected to the outer wall of the large oxygen chamber 1, a small oxygen chamber 102 is fixedly connected to one end of the first aisle 101, and a second aisle 103 is fixedly connected to the outer wall of the small oxygen chamber 102; a sealing component, the sealing component is used to seal the hyperbaric oxygen chamber, and the sealing component is respectively connected to the first aisle 101 and the second aisle 103.

[0044] Specifically, the large oxygen chamber 1 is hollow hemispherical and made of metal, which can effectively resist physical and chemical effects under high pressure environment. At least two first aisles 101 are respectively fixedly connected to the outer wall of the large oxygen chamber 1 and are distributed in a circular array. The first aisle 101 is a metal hollow cuboid as a whole. The patient can walk into the large oxygen chamber 1 from the inner wall of the first aisle 101 for treatment. The small oxygen chamber 102 is fixedly connected to one end of the first aisle 101 away from the large oxygen chamber 1. The small oxygen chamber 102 is hollow hemispherical and made of metal, which can effectively resist physical and chemical effects under high pressure environment. The volume of the small oxygen chamber 102 is smaller than that of the large oxygen chamber 1. One end of the second aisle 103 is fixedly connected to the small oxygen chamber 102. The second aisle 103 is a metal hollow cuboid as a whole. The patient can enter the small oxygen chamber 102 through the second aisle 103.

[0045] The large oxygen chamber 1 and the small oxygen chamber 102 are respectively connected to the same oxygen concentrator through standard high-pressure valves, and at least two small oxygen chambers 102 are equipped with independent pressurization and decompression control systems, and real-time monitoring and adjustment of pressure are achieved with the help of pressure sensors. The two cabin entrances 3 inside and outside the small oxygen chamber 102 are provided with an interlocking system to ensure that the cabin door cannot be opened when the pressure is not balanced. After the patient enters the small oxygen chamber 102, the small oxygen chamber 102 is independently pressurized until the internal pressure is the same as that of the large oxygen chamber 1. After the pressure is balanced, the cabin door is automatically unlocked, and the patient can enter the large oxygen chamber 1. When the patient returns to the small oxygen chamber 102 from the large oxygen chamber 1, the pressure of the small oxygen chamber 102 will gradually decrease to the same as the external environment pressure. At this time, the cabin door is unlocked and the patient can leave. At the beginning of treatment, the large oxygen chamber 1 only performs a pressurization operation once, and then maintains a stable pressure to avoid frequent pressure increase and decrease, and the patient's entry and exit are completed through the small oxygen chamber 102. This design significantly reduces the energy consumption of the large oxygen chamber 1, and also reduces the waiting time for patients waiting for treatment, meeting the multi-user processing needs in emergency situations. The sealing assembly provided by the present invention can be used to seal the hyperbaric oxygen chamber. By setting the sealing assembly, not only can the hyperbaric oxygen chamber be sealed to ensure the stability of the air pressure in the chamber and avoid energy loss, but also a self-compensation effect can be provided after the sealing ring 4 is worn. In addition, when the sealing ring 4 is damaged, it is convenient for the operator to remove the sealing ring 4.

[0046] like Figures 1 to 12 As shown, the sealing assembly includes a first door frame 2 and a second door frame 201, and the first door frame 2 and the second door frame 201 are respectively installed in the middle of the first aisle 101 and one end of the second aisle 103, the first door frame 2 and the second door frame 201 are both provided with a first clamping groove 204 on the inner wall, a clamping protrusion 202 is fixedly connected to the inner wall of the first clamping groove 204, an oil delivery groove 203 is provided inside the clamping protrusion 202, second clamping grooves 205 are symmetrically provided on the inner walls of both sides of the first clamping groove 204, and a sealing ring 4 is clamped on the inner wall of the first clamping groove 204. Specifically, the sealing assembly includes a first door frame 2 and a second door frame 201, wherein the first door frame 2 is installed in the middle of the first aisle 101 The second door frame 201 is installed at one end of the second aisle 103. The first door frame 2 is a hollow metal circular plate. The outer wall of the first door frame 2 close to the large oxygen chamber 1 and the outer wall of the second door frame 201 close to the small oxygen chamber 102 are respectively installed with cabin entrance doors 3. The circular cabin entrance doors 3 made of metal are disclosed in the prior art, so they are not described in detail. Patients can enter the small oxygen chamber 102 and the large oxygen chamber 1 respectively through the two cabin entrance doors 3. To ensure the safety of the hyperbaric oxygen chamber, the two cabin entrance doors 3 are equipped with an interlocking system, which monitors the pressure inside and outside the cabin in real time. When the pressure is not balanced, the control signal for opening the cabin door will be automatically blocked, effectively avoiding the cabin door opening due to misoperation or accident. The cabin door can only be opened normally after the pressure is balanced.

[0047] The two first clamping grooves 204 are respectively provided on the inner wall of the first door frame 2 and the second door frame 201. The first clamping groove 204 is a circular square groove. The clamping protrusion 202 is fixedly connected to the inner wall of the first clamping groove 204 near the top of the second passage 103. The clamping protrusion 202 is a gourd-shaped metal block. The oil delivery groove 203 is provided inside the clamping protrusion 202. The oil delivery groove 203 is a circular groove body. The two oil delivery grooves 203 respectively penetrate from the outer wall of the first door frame 2 and the second door frame 201. The oil delivery groove 203 is used to deliver the oil used for sealing. The sealing liquid is transported to the inside of the sealing ring 4 through the oil delivery groove 203. The above structural setting can seal the cabin door 3 after the patient enters the cabin to prevent oxygen leakage and energy loss.

[0048] The inner wall of the sealing ring 4 is sleeved with a first frame 401, and a plurality of arc-shaped elastic plates 406 distributed in a circumferential array are fixedly connected to the inner wall of the first frame 401. The outer walls on both sides of the first frame 401 are respectively fixedly connected with a second frame 402 and a third frame 403. One end of the second frame 402 is fixedly connected with a C-shaped elastic plate 404, and one end of the C-shaped elastic plate 404 is fixedly connected with an L-shaped frame 405. The outer walls of the C-shaped elastic plate 404 and the L-shaped frame 405 are both provided with a plurality of segmented grooves 407. Specifically, the first frame 401 is sleeved on the inner wall of the sealing ring 4. The first frame 401 is a hollow plastic cylinder. The width of the first frame 401 is The degree is adapted to the inner wall contour of the first clamping groove 204, one end of a plurality of arc-shaped elastic plates 406 is fixedly connected to the inner wall of the first skeleton 401, and the plurality of arc-shaped elastic plates 406 are distributed in a circular array. The arc-shaped elastic plates 406 are composed of two parts, an arc-shaped plastic plate and an arc-shaped cylinder. The contour formed by the plurality of arc-shaped elastic plates 406 is adapted to the contour of the clamping protrusion 202 mentioned above. When the plurality of arc-shaped elastic plates 406 are clamped with the clamping protrusion 202, the arc-shaped elastic plates 406 will be subjected to extrusion force and deform along the direction of their bending, so that the plurality of arc-shaped elastic plates 406 cooperate with each other and can be clamped on the outer wall of the clamping protrusion 202.

[0049] Specifically, the second frame 402 is fixedly connected to the outer wall of the first frame 401 on one side close to the cabin door 3, and the third frame 403 is fixedly connected to the outer wall of the side away from the first frame 401. The second frame 402 and the third frame 403 are both composed of three parts: a "C"-shaped plastic plate in the middle and hollow plastic circular plates at both ends. The parts of the second frame 402 and the third frame 403 with the "C"-shaped plastic plate are adapted to the inner wall contour of the second clamping groove 205 mentioned above. Therefore, the first frame 401, the second frame 402 and the third frame 403 cooperate with the second clamping groove 205 to clamp the sealing ring 4 to the inner wall of the first clamping groove 204. During the process, several arc-shaped elastic plates 406 on the first frame 401 are firstly snapped into engagement with the snap-in protrusions 202. At this time, the arc-shaped elastic plates 406 will be subjected to the squeezing force from the snap-in protrusions 202 and deformed along the direction of their bending. Then, the second frame 402 and the third frame 403 are pressed into the first snap-in groove 204. The portion of the second frame 402 and the third frame 403 having the "C"-shaped plastic plate will be subjected to the squeezing force from the inner wall of the first snap-in groove 204 and deformed along the direction of their bending, until the portion of the second frame 402 and the third frame 403 having the "C"-shaped plastic plate slides into the inner wall of the second snap-in groove 205, and the snap-in can be completed.

[0050] The width of the second frame 402 is greater than the width of the third frame 403, one end of the C-shaped elastic plate 404 is fixedly connected to the end of the second frame 402 away from the first frame 401, the C-shaped elastic plate 404 is a "C"-shaped plastic plate, and when the C-shaped elastic plate 404 is subjected to force, it will deform along the direction of its bending, one end of the L-shaped frame 405 is fixedly connected to the end of the C-shaped elastic plate 404 away from the second frame 402, and the other end of the L-shaped frame 405 is fixedly connected to the end of the third frame 403 away from the first frame 401, and a plurality of segmented grooves 407 are provided on the outer walls of the C-shaped elastic plate 404 and the L-shaped frame 405, and the segmented grooves 407 are square groove bodies, which can adapt to the contour of the cabin door 3 and improve the sealing effect of the cabin door 3. After using this device for a long time, the sealing ring 4 is severely worn and cannot be used normally. You can pinch the outer walls of the two ends of the C-shaped elastic plate 404 with force. After the C-shaped elastic plate 404 is subjected to force, it will deform along its bending direction, driving the parts of the second frame 402 and the third frame 403 with the "C"-shaped plastic plate to be subjected to force and deform along their respective bending directions. At this time, the sealing ring 4 can be pulled out of the first clamping groove 204 and replaced with a new sealing ring 4, which saves costs. The above structural setting can not only shape the sealing ring 4, but also adapt to the contour of the cabin door 3, thereby improving the sealing effect of the cabin door 3. In addition, after the sealing ring 4 is severely worn, it is convenient for maintenance personnel to replace the new sealing ring 4, thereby saving costs.

[0051] In this embodiment, if Figures 1 to 12 As shown, the first cylinder 5 is fixedly connected to the top outer wall of the second passage 103, the second cylinder 501 is fixedly connected to the top outer wall of the first cylinder 5, a scale 502 is provided on the outer wall of the second cylinder 501, the first piston plate 7 is slidably connected to the inner wall of the first cylinder 5, a spring 701 is fixedly connected to the top outer wall of the first piston plate 7, a support column 702 is fixedly connected to the top outer wall of the first piston plate 7, and one end of the support column 702 is fixedly connected to the second piston plate 703.

[0052] Specifically, one end of the first cylinder 5 is fixedly connected to the middle position of the top outer wall of the second passage 103, the first cylinder 5 is a hollow metal cylinder with a cap, and a avoidance hole is opened on the top of the first cylinder 5, one end of the second cylinder 501 is fixedly connected to the top outer wall of the first cylinder 5, the second cylinder 501 is a glass cylinder with a cap, wherein the volume of the second cylinder 501 is smaller than the volume of the first cylinder 5, and the second cylinder 501 is filled with a sealing liquid, which is disclosed in the prior art, so it is not described. Without going into details, the scale 502 is arranged on the outer wall of the second cylinder 501, the first piston plate 7 is slidably connected to the inner wall of the first cylinder 5, the first piston plate 7 is composed of two parts, a plastic cylinder and a semicircular rubber ring, wherein the semicircular rubber ring is located in the middle of the outer wall of the plastic cylinder, and one end of the spring 701 is fixedly connected to the top outer wall of the first piston plate 7, and the other end of the spring 701 is fixedly connected to the top inner wall of the first cylinder 5. The spring 701 is disclosed in the prior art, so it is not described in detail.

[0053] When the small oxygen cabin 102 begins to be pressurized, the pressurized gas will push the first piston plate 7 to move toward the top of the first cylinder 5. At this time, the spring 701 will be squeezed by the first piston plate 7 and will deform along the direction of its bending. On the contrary, when the small oxygen cabin 102 begins to be depressurized, the first piston plate 7 is no longer pushed by the pressurized gas, and the spring 701 is no longer squeezed. It will recover its deformation under the action of its own elasticity and push the first piston plate 7 to move toward the bottom of the second aisle 103. One end of the support column 702 is fixedly connected to the top outer wall of the first piston plate 7. The support column 702 is a plastic cylinder. The other end of the support column 702 passes through the avoidance hole opened on the top outer wall of the first cylinder 5 and is fixedly connected to the bottom outer wall of the second piston plate 703. 703 is composed of three parts: a plastic cylinder and two semicircular rubber rings, wherein the two semicircular rubber rings are respectively located on the outer wall of the plastic cylinder near the top and near the bottom. The contour of the second piston plate 703 is adapted to the contour of the inner wall of the second cylinder 501, so the second piston plate 703 can slide on the inner wall of the second cylinder 501. Since the first piston plate 7, the support column 702 and the second piston plate 703 are an integrated structure, the second piston plate 703 will move along with the displacement of the first piston plate 7. With the above structural arrangement, the second piston plate 703 can be pushed to move by pressurizing the small oxygen cabin 102, thereby pushing out the sealing liquid in the second cylinder.

[0056] Specifically, the second threaded column 603 is screwed on the outer wall of the fourth cylinder 504 away from the second cylinder 501. The second threaded column 603 is an acrylic cylinder with a thread groove on the outer wall, wherein the thread profile on the outer wall of the second threaded column 603 is adapted to the profile of the thread groove provided on the fourth cylinder 504, so the second threaded column 603 can rotate on the fourth cylinder 504, and the second anti-slip handle 604 is fixedly connected to one end of the second threaded column 603.

[0057] When the patient enters the small oxygen chamber 102 and prepares to enter the large oxygen chamber 1, the cabin entrance door 3 on the second door frame 201 is closed first, and then the small oxygen chamber 102 is pressurized. The pressurized gas will push the first piston plate 7 to move toward the top of the first cylinder 5, and the second piston plate 703 will move with the first piston plate 7. At this time, the sealing liquid at the top of the second piston plate 703 in the second cylinder 501 will be transmitted to the sealing ring 4 clamped on the second door frame 201 through the second oil pipeline 506. At this time, the spring 701 is squeezed by the first piston plate 7 and deformed along the bending direction. The maintenance personnel can check whether the sealing liquid level at the top of the second piston plate 703 rises by observing the scale 502 on the second cylinder 501, so as to judge whether the sealing ring 4 is worn. If the liquid level rises, it means that the second door frame 20 1 has been worn. To ensure the sealing effect of the sealing ring 4, the maintenance personnel can rotate the first anti-slip handle 601 clockwise to rotate the first threaded column 6 and push the third piston plate 602 to move toward the second cylinder 501. The third piston plate 602 pushes the sealing liquid in the third cylinder 503 to the second cylinder 501, and then transmits it to the sealing ring 4 clamped on the second door frame 201 through the second oil pipe 506, pressurizing the sealing liquid in the sealing ring 4 to play a compensatory role and maintain the sealing of the sealing ring 4. At the same time, the sealing liquid of the sealing ring 4 on the first door frame 2 will be drawn back into the second cylinder 501 through the first oil pipe 505. After the small oxygen cabin 102 is pressurized and the air pressure in the cabin is consistent with that of the large oxygen cabin 1, the cabin entrance door 3 in the first aisle 101 can be opened to facilitate patients to enter the large oxygen cabin 1 for treatment.

[0058] When the patient is ready to go out of the small oxygen chamber 102, the entrance door 3 on the first door frame 2 is closed first, and then the small oxygen chamber 102 begins to be decompressed. At this time, the first piston plate 7 is no longer pushed by the pressurized gas, and the spring 701 is no longer squeezed. It recovers its deformation under its own elasticity and pushes the first piston plate 7 to move toward the second aisle 103. The second piston plate 703 will move along with the first piston plate 7, and the sealing liquid at the bottom of the second piston plate 703 in the second cylinder 501 will be transmitted to the sealing ring 4 clamped on the second door frame 201 through the first oil pipe 505. At this time, the maintenance personnel can observe the scale 502 on the second cylinder 501 to check whether the liquid level of the sealing liquid at the bottom of the second piston plate 703 has dropped, so as to judge whether the sealing ring 4 is worn. If the liquid level has dropped, it means that the sealing ring 4 on the first door frame 2 has been worn. To ensure the sealing effect of the sealing ring 4, the maintenance personnel can rotate the second anti-slip handle 604 clockwise to rotate the second threaded column 603 and push the fourth piston plate 605 to move toward the second cylinder 501. The fourth piston plate 605 pushes the sealing liquid in the fourth cylinder 504 toward the second cylinder 501, and then transmits it to the sealing ring 4 clamped on the first door frame 2 through the first oil pipe 505, pressurizes the sealing liquid in the sealing ring 4, plays a compensatory role, and maintains the sealing performance of the sealing ring 4. At the same time, the sealing liquid of the sealing ring 4 on the second door frame 201 will be pumped back into the second cylinder 501 through the second oil pipe 506. After the small oxygen cabin 102 is decompressed and the air pressure inside the cabin is consistent with that outside the cabin, the cabin entrance door 3 in the second aisle 103 can be opened to facilitate the exit of patients after the treatment. The above structural setting can not only realize the sealing of the cabin entrance door 3 by pressurizing the small oxygen cabin 102, but also provide a self-compensation effect for the sealing ring 4 after the sealing ring 4 is worn.

[0059] The workflow of the technical solution provided by the present invention is as follows:

[0060] When the patient enters the small oxygen chamber 102 and prepares to enter the large oxygen chamber 1, the cabin door 3 on the second door frame 201 is closed first, and then the small oxygen chamber 102 is pressurized. The pressurized gas pushes the first piston plate 7 to move toward the top of the first cylinder 5, and the second piston plate 703 moves synchronously with the first piston plate 7. At this time, the sealing liquid at the top of the second piston plate 703 in the second cylinder 501 is transmitted to the sealing ring 4 clamped on the second door frame 201 through the second oil pipeline 506. The spring 701 is squeezed by the first piston plate 7 and deformed in the bending direction. The maintenance personnel can observe the scale 502 on the second cylinder 501 to see whether the sealing liquid level at the top of the second piston plate 703 rises, so as to judge whether the sealing ring 4 is worn. If the liquid level rises, it indicates that the sealing ring 4 on the second door frame 201 is worn.

[0061] To ensure the sealing effect of the sealing ring 4, the maintenance personnel can rotate the first anti-slip handle 601 clockwise to rotate the first threaded column 6 and push the third piston plate 602 to move toward the second cylinder 501. The third piston plate 602 pushes the sealing liquid in the third cylinder 503 to the second cylinder 501, and then transmits it to the sealing ring 4 clamped on the second door frame 201 through the second oil pipeline 506, pressurizing the sealing liquid in the sealing ring 4, playing a compensatory role, and maintaining the sealing of the sealing ring 4. At the same time, the sealing liquid of the sealing ring 4 on the first door frame 2 is pumped back into the second cylinder 501 through the first oil pipeline 505. After the small oxygen cabin 102 is pressurized and the air pressure in the cabin is consistent with that of the large oxygen cabin 1, the cabin door 3 in the first aisle 101 can be opened to facilitate patients to enter the large oxygen cabin 1 for treatment.

[0062] When the patient is ready to go out of the small oxygen cabin 102, first close the cabin door 3 on the first door frame 2, and then decompress the small oxygen cabin 102. At this time, the first piston plate 7 is no longer pushed by the pressurized gas, and the spring 701 is no longer squeezed. It recovers its deformation under its own elasticity, pushing the first piston plate 7 to move toward the second aisle 103, and the second piston plate 703 moves accordingly. The sealing liquid at the bottom of the second piston plate 703 in the second cylinder 501 is transmitted to the sealing ring 4 clamped on the second door frame 201 through the first oil pipeline 505. The maintenance personnel can check whether the sealing liquid level at the bottom of the second piston plate 703 drops by observing the scale 502 on the second cylinder 501, so as to judge whether the sealing ring 4 is worn. If the liquid level drops, it means that the sealing ring 4 on the first door frame 2 is worn.

[0063] To ensure the sealing effect of the sealing ring 4, the maintenance personnel can rotate the second anti-slip handle 604 clockwise to rotate the second threaded column 603 and push the fourth piston plate 605 to move toward the second cylinder 501. The fourth piston plate 605 pushes the sealing liquid in the fourth cylinder 504 to the second cylinder 501, and then transmits it to the sealing ring 4 clamped on the first door frame 2 through the first oil pipeline 505, pressurizes the sealing liquid in the sealing ring 4, plays a compensatory role, and maintains the sealing of the sealing ring 4. At the same time, the sealing liquid of the sealing ring 4 on the second door frame 201 is drawn back into the second cylinder 501 through the second oil pipeline 506. After the small oxygen cabin 102 is decompressed and the air pressure inside the cabin is consistent with that outside the cabin, the cabin door 3 in the second aisle 103 can be opened to facilitate the patient to go out after the treatment. The above structural setting can not only realize the sealing of the cabin door 3 by pressurizing the small oxygen cabin 102, but also provide a self-compensation function for the sealing ring 4 after the sealing ring 4 is worn.

[0064] After using the device for a long time, the sealing ring 4 is seriously worn and cannot be used normally. You can pinch the outer walls of the two ends of the C-shaped elastic plate 404. After the force is applied, the C-shaped elastic plate 404 will deform along the direction of its bending, driving the parts of the second frame 402 and the third frame 403 with the "C"-shaped plastic plate to be stressed and deform along the directions of their respective bending. At this time, the sealing ring 4 can be pulled out of the first clamping groove 204. When replacing a new sealing ring 4, first align the several arc-shaped elastic plates 406 on the first frame 401 with the clamping protrusions 202. The arc-shaped elastic plate 406 is then clamped together, and the arc-shaped elastic plate 406 is squeezed by the clamping protrusion 202 and deformed in the direction of its bending. Then the second frame 402 and the third frame 403 are pressed into the first clamping groove 204, and the part of the second frame 402 and the third frame 403 with the "C"-shaped plastic plate is squeezed by the inner wall of the first clamping groove 204 and deformed in the direction of its bending, until the part of the second frame 402 and the third frame 403 with the "C"-shaped plastic plate slides onto the inner wall of the second clamping groove 205.
