Description

Technical Field

[0001] The present invention relates to the technical field of hyperbaric oxygen chambers, and in particular to a mechanically pressurized hyperbaric oxygen chamber. Background Art

[0002] The oxygen chamber is a special medical device for hyperbaric oxygen therapy. Its principle is to place the user in an oxygen-rich environment with 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, thereby increasing the level of arterial oxygen partial pressure and oxygen saturation to promote human metabolism.

[0003] At present, the commonly used method of pressurizing the hyperbaric oxygen chamber is the inflation method, which uses an air compressor to provide high-pressure gas and fill it into the oxygen chamber to achieve pressurization. The advantage of air compressors is that they are quite mature and can provide stable pressure output. At present, air compressor pressurization equipment basically has automatic control functions, which is easy to operate and reduces the technical requirements of operators.

[0004] However, based on consumer feedback, some limitations of existing air compressor pressurization were discovered.

[0005] First of all, when the usage scenario is a power outage scenario, a power outage scenario, or a voltage unstable scenario, it is often impossible to use an air compressor to inflate, which may cause delayed treatment.

[0006] Secondly, the air compressor will generate a lot of noise during operation, and the gas will also generate a lot of noise after entering the oxygen chamber. Although most oxygen chambers are currently equipped with silencers at key locations such as the air inlet and exhaust ports, there is still obvious noise, which will cause discomfort to users who have high requirements for quietness. Summary of the invention

[0007] The present invention provides a mechanically pressurized hyperbaric oxygen chamber to solve the technical problem that the pressurization technology in the prior art is difficult to use in a power-free scenario.

[0008] In order to solve the above problems, the mechanically pressurized hyperbaric oxygen chamber provided by the present invention adopts the following technical solutions: The treatment cabin comprises an oxygen inlet and an exhaust gas outlet, the oxygen inlet is connected to an oxygen tank, an oxygen mask for a user to breathe oxygen is also provided in the treatment cabin, the air inlet of the oxygen mask is connected to the oxygen inlet, and the exhaust port of the oxygen mask is connected to the exhaust gas outlet; A pressurized cabin, the pressurized cabin is connected to the treatment cabin through a connecting cabin passage, the pressurized cabin includes a cabin body and a pressurizing mechanism for pressurizing the treatment cabin, the pressurizing mechanism includes a movable pressurizing plate slidably mounted in the cabin body and a driving structure for driving the movable pressurizing plate to slide in the cabin body, the movable pressurizing plate is in contact with the inner wall of the cabin body, and a balancing opening for balancing air pressure is provided on a side of the cabin body away from the treatment cabin; The movable pressurization plate has a pressurization position and a release position on its sliding stroke. The movable pressurization plate in the pressurization position moves to the side close to the treatment cabin, and the air in the cabin body together with the air in the treatment cabin are compressed and pressurized, and the air pressure in the treatment cabin reaches the required pressure; the movable pressurization plate in the release position moves to the side away from the treatment cabin, and the pressure in the cabin body and the treatment cabin is reduced to balance with the external atmospheric pressure.

[0009] By adopting the above technical solution, the problem that the existing air compressor boosting technology is difficult to use in scenarios without power supply is solved. The oxygen inlet of the treatment cabin can be directly connected to the oxygen tank, and no power supply is required during the oxygen supply process. The oxygen supply pipeline is an independent pipeline. When the user wears an oxygen mask, the oxygen supply pipeline is separated from the treatment cabin, that is, the air in the treatment cabin will not be discharged from the exhaust outlet, ensuring that the air pressure in the treatment cabin can maintain the required pressure for a long time.

[0010] The pressurization principle of the present invention is that the cabin body and the movable pressurization plate form a pressurization chamber, and the pressurization chamber is connected to the treatment cabin. When the movable pressurization plate moves toward one side of the treatment cabin, the space of the pressurization chamber shrinks, and the air in the pressurization chamber and the treatment cabin is compressed together to achieve manual pressurization.

[0011] As a further improvement, the driving structure is a lead screw, the lead screw is connected to the cabin body through a bearing, and the lead screw is connected to the movable pressure plate through a thread.

[0012] By adopting the above technical solution, it is convenient to manually drive the movable pressure plate to move. The driving structure is a screw structure. When the screw is rotated, the movable pressure plate can be translated, and the movable pressure plate can be driven to translate with a relatively small force. The screw structure has good stability and is not prone to deviation.

[0013] As a further improvement, a support frame fixedly connected to the cabin body is provided on a side of the pressurization cabin away from the treatment cabin, and the lead screw is connected to the support frame via a bearing.

[0014] The support frame is mainly used to support the lead screw and ensure the stability of the lead screw.

[0015] As a further improvement, a spring is fixedly connected to one side of the movable pressure plate away from the treatment cabin, and the other end of the spring is fixedly connected to the support frame.

[0016] By adopting the above technical solution, the stability of the movable pressure plate is further improved, and the spring can provide thrust to the pressure plate and maintain the balance of the pressure plate.

[0017] As a further improvement, the lead screw extends into the treatment cabin, a rotary steering wheel is provided in the treatment cabin, the rotary steering wheel is fixedly connected to the lead screw, and the lead screw is connected to the treatment cabin via a bearing.

[0018] By adopting the above technical solution, the user can manually adjust the air pressure in the treatment cabin, so that the present invention can be applied to special scenarios such as no power supply. In addition, the present invention has extremely low noise and almost no noise during operation, which can avoid discomfort for some users with high requirements for silence.

[0019] As a further improvement, the treatment cabin is also provided with a pressure gauge for detecting the internal pressure of the treatment cabin and a manual pressure relief valve for accelerating pressure relief.

[0020] The manual pressure relief valve is used to speed up the pressure relief during pressure relief.

[0021] As a further improvement, a cabin door is provided on a side of the treatment cabin away from the pressurization cabin.

[0022] As a further improvement, a sealing ring is also provided on the movable pressure plate.

[0023] The beneficial effects of the above technical solution of the present invention are as follows: 1. The present invention provides a manually driven movable pressurization plate. When the steering wheel is turned, the movable pressurization plate moves to one side of the treatment cabin, and the air in the pressurization cabin is compressed and pressurized together with the air in the treatment cabin, thereby realizing the operation of the oxygen cabin in a power-free scenario, which makes up for some limitations of the existing air compressor pressurization technology.

[0024] 2. The present invention generates almost no noise during operation, which can meet the needs of some users with high requirements for quietness and provide new options for these users. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0028] In the prior art, the high-pressure oxygen chamber uses an air compressor to provide high-pressure gas, which is then filled into the oxygen chamber to achieve pressurization. During use, some consumers have reported that when extreme weather occurs, local power outages will occur, which will cause the high-pressure oxygen chamber to be unable to operate normally, resulting in delayed treatment. In addition, the air compressor will generate a lot of noise during operation, and the gas will also generate a lot of noise after entering the oxygen chamber, which will cause discomfort to users who have high requirements for silence.

[0029] In view of the above problems, the present invention designs a manually pressurized hyperbaric oxygen chamber, which includes a treatment chamber 100 and a pressurization chamber 300, and the treatment chamber 100 is connected with the pressurization chamber 300. When the steering wheel 317 is turned, the movable pressurization plate 315 moves toward the treatment chamber 100, and the air in the pressurization chamber 300 is compressed and pressurized together with the air in the treatment chamber 100, thereby realizing the operation of the oxygen chamber in a power-free scenario.

[0030] Manual pressurization requires a large force, especially when the air pressure in the treatment cabin 100 increases, further pressurization requires a large force. The present invention adopts a driving structure as a lead screw 311 to reduce the force required to drive the movable pressurization plate 315. At the same time, four springs 312 are used to push the movable pressurization plate 315 to prevent the movable pressurization plate 315 from deflecting, ensuring that the treatment cabin 100 can maintain the required air pressure for a long time.

[0031] After introducing the basic principle of the present invention, various non-limiting embodiments of the present invention are described in detail below. The number of any element in the drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning.

[0032] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0033] Embodiment 1 of the mechanically pressurized hyperbaric oxygen chamber provided by the present invention: like Figure 1-Figure 5 As shown, a treatment cabin 100 is provided for a user 400 to enter for treatment and a compression cabin 300 is provided for pressurizing the squeeze space.

[0034] like Figure 1 , 2 As shown in Figures 4 and 5, a door 130 is provided on the side of the treatment cabin 100 away from the pressurized cabin 300. An oxygen inlet 150 and an exhaust gas outlet 120 are respectively provided on the treatment cabin 100. The oxygen inlet 150 is connected to the oxygen tank 500. An oxygen mask 510 for the user 400 to breathe oxygen is also provided in the treatment cabin 100. The air inlet of the oxygen mask 510 is connected to the oxygen inlet 150, and the exhaust port of the oxygen mask 510 is connected to the exhaust gas outlet 120.

[0035] The treatment cabin 100 is also provided with a pressure gauge 140 for detecting the internal pressure of the treatment cabin 100 and a manual pressure relief valve 110 for accelerating pressure relief.

[0036] When the user 400 wears the oxygen mask 510 , an independent airway space is formed in the oxygen mask 510 . At this time, the user 400 can inhale oxygen and expel waste gas in the airway space, and the treatment cabin 100 is completely sealed.

[0037] like Figure 1-Figure 5 As shown, the pressurization cabin 300 is connected with the treatment cabin 100 through a connecting cabin channel 200. In the present embodiment, four connecting cabin channels 200 are provided. The pressurization cabin 300 includes a cabin body and a pressurization mechanism for pressurizing the treatment cabin 100. The pressurization mechanism includes a movable pressurization plate 315 slidably assembled in the cabin body and a driving structure for driving the movable pressurization plate 315 to slide in the cabin body. The movable pressurization plate 315 is in contact with the inner wall of the cabin body, and a sealing ring 314 is also provided on the movable pressurization plate 315. In the present embodiment, three sealing rings 314 are provided. A balancing opening for balancing the air pressure is provided on the side of the cabin body away from the treatment cabin 100.

[0038] like Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, the cabin is in a semi-enclosed form, the open end of the cabin forms a balancing opening, and the movable pressurizing plate 315 is assembled in the cabin from the open end of the cabin.

[0039] The movable pressurization plate 315 has a pressurization position and a release position on its sliding stroke. When the movable pressurization plate 315 is in the pressurization position, it moves to the side close to the treatment cabin 100, and the air in the cabin body together with the air in the treatment cabin 100 is compressed and pressurized, and the air pressure in the treatment cabin 100 reaches the required pressure; when the movable pressurization plate 315 is in the release position, it moves to the side away from the treatment cabin 100, and the pressure in the cabin body and the treatment cabin 100 is reduced to balance with the external atmospheric pressure.

[0040] like Figure 3 As shown, in this embodiment, the driving structure is a lead screw 311, which is connected to the cabin through a bearing 316, and the lead screw 311 is connected to the movable pressure plate 315 through a thread. When the lead screw 311 is rotated, the movable pressure plate 315 can be translated, and the movable pressure plate 315 can be driven to translate with a relatively small force, and the lead screw 311 has good structural stability and is not prone to deviation.

[0041] In other embodiments, a sealing sleeve may be provided on each side of the movable pressure plate 315 , the sealing sleeve is fixedly connected to the movable pressure plate 315 , and the inner wall of the sealing sleeve is provided with a thread matching with the lead screw 311 , thereby improving the sealing of the driving structure.

[0042] like Figure 1 and Figure 2 As shown, a support frame 313 fixedly connected to the cabin body is provided on the side of the pressurized cabin 300 away from the treatment cabin 100, and the lead screw 311 is connected to the support frame 313 through a bearing 316. The support frame 313 is mainly used to support the lead screw 311 to ensure the stability of the lead screw 311.

[0043] like Figure 1-Figure 3 As shown, a spring 312 is fixedly connected to one side of the movable pressure plate 315 away from the treatment cabin 100, and the other end of the spring 312 is fixedly connected to the support frame 313. The spring 312 is provided with four strips, and circular grooves for installing the spring 312 are provided on the movable pressure plate 315 and the support frame 313, so as to facilitate the installation of the spring 312.

[0044] The spring 312 can further improve the stability of the movable pressure plate 315 . The spring 312 can provide a thrust to the pressure plate and maintain the balance of the pressure plate.

[0045] The lead screw 311 extends into the treatment cabin 100, and a screw steering wheel 317 is provided in the treatment cabin 100. The screw steering wheel 317 is fixedly connected to the lead screw, and the lead screw 311 is connected to the treatment cabin 100 through a bearing 316. In this embodiment, the bearing 316 uses a bearing 316 with a sealing effect to ensure the sealing of the treatment cabin 100 and the pressurized cabin 300.

[0046] The rotary steering wheel 317 is arranged in the treatment cabin 100, and the user 400 can manually adjust the air pressure in the treatment cabin 100, so that the present invention can be applied to special scenarios such as no power supply. In addition, the present invention has very little noise during operation, almost no noise, which can avoid discomfort to some users 400 who have high requirements for silence.

[0047] When the present invention is used, the movable pressurizing plate 315 is moved to the outside in the initial state, and after the pipeline is connected, the user 400 enters the cabin and closes the cabin door 130. When the user 400 does not wear the oxygen mask 510, since the exhaust port is directly connected to the treatment cabin 100, the pressure in the treatment cabin 100 is balanced with the atmospheric pressure. At this time, even if the steering wheel 317 is rotated to move the movable pressurizing plate 315, the pressure in the treatment cabin 100 will not rise. When the user 400 wears the oxygen mask 510, an independent airway space is formed in the oxygen mask 510. At this time, the user 400 can inhale oxygen and exhaust exhaust gas in the airway space, and the treatment cabin 100 is completely sealed. When the user 400 rotates the rotary knob 317 clockwise, the movable pressurizing plate 315 moves inward, and the air in the pressurized cabin 300 is compressed and pressurized together with the air in the treatment cabin 100, and the pressure in the treatment cabin 100 rises. As the rotary knob 317 rotates continuously, the pressure continues to rise. When the pressure rises to the required pressure, the rotary knob 317 is stopped, and the pressure in the treatment cabin 100 can be maintained unchanged, and the user 400 starts continuous treatment. When the treatment is completed, the user 400 can rotate the rotary knob 317 counterclockwise, and the movable pressurizing plate 315 moves outward to reduce the pressure in the cabin. When rapid pressure relief is required, the manual pressure relief valve 110 can be rotated to relieve pressure and speed up the pressure relief.

[0048] Embodiment 2 of the mechanically pressurized hyperbaric oxygen chamber provided by the present invention: The main difference between it and Example 1 is: In Example 1, the lead screw extends into the treatment cabin, and a rotary steering wheel is provided in the treatment cabin, and the rotary steering wheel is fixedly connected to the lead screw.

[0049] In this embodiment, two rotary steering wheels are provided, one of which is arranged inside the treatment cabin, and the other is arranged on the side of the support frame away from the pressure cabin, so that the movable pressure plate can be driven to increase pressure from inside the treatment cabin, and the movable pressure plate can also be driven to increase pressure from the outside.

[0050] Embodiment 3 of the mechanically pressurized hyperbaric oxygen chamber provided by the present invention: The main difference between it and Example 2 is: In this embodiment, a reduction motor is installed on the support frame, and the reduction motor is connected to the lead screw through transmission, and specifically, gear meshing can be adopted.

[0051] Specifically, the reduction motor is installed on the base, and the base is slidably assembled on the support frame along the up-down direction. The support frame is also provided with a manual lifting structure, and the manual lifting structure is used to drive the base to lift.

[0052] When there is power, the pressure mechanism can be driven by the reduction motor to operate, and the machine can replace manual work; in the scenario where there is no power, the gears of the reduction motor and the pressure mechanism are separated, and the pressure mechanism is manually driven to operate.

[0053] In this embodiment, the manual lifting structure may adopt a screw lifting structure.

[0054] Although this specification has shown and described a plurality of embodiments of the present invention, it is obvious to those skilled in the art that such embodiments are provided by way of example only. Those skilled in the art will think of many changes, modifications and alternatives without departing from the thought and spirit of the present invention. It should be understood that in the process of practicing the present invention, various alternatives to the embodiments of the present invention described herein may be adopted.
