Description

Technical Field

[0001] This utility model relates to the technical field of oxygen depletion devices, specifically an oxygen depletion device for a medical hyperbaric oxygen chamber. Background Technology

[0002] A hyperbaric oxygen chamber is a specialized medical device for hyperbaric oxygen therapy. Depending on the pressurizing medium, it is divided into two types: air hyperbaric chamber and pure oxygen hyperbaric chamber. Hyperbaric oxygen chambers have a wide range of applications and are mainly used clinically for the treatment of diseases such as anaerobic bacterial infections, carbon monoxide poisoning, traumatic brain injury, decompression sickness, and hypoxic-ischemic encephalopathy. Hyperbaric oxygen chambers use oxygen exhaust devices.

[0003] According to a public announcement of an independent oxygen exhaust device for a hyperbaric oxygen chamber (Announcement No.: CN223248456U), the aforementioned application utilizes a gas storage component to temporarily store the gas in the hyperbaric oxygen chamber. A diversion component evenly distributes the exhaust gas from the hyperbaric oxygen chamber to the dust removal mechanism, which in turn removes dust from the transported gas, improving the device's practicality. A connecting mechanism facilitates cleaning and replacement of the dust removal mechanism. A gas dispersing mechanism widely discharges the dust-removed gas into the sterilization mechanism, which then performs high-temperature sterilization on the discharged gas, further enhancing the device's practicality and versatility.

[0004] However, in actual use, the inner wall of the air inlet pipe will continuously accumulate and adhere to dust and debris as gas is continuously transported. The added filter needs to be stopped and removed when cleaning or when it becomes clogged, which will cause inconvenience such as interruption of equipment use. In view of this, we propose an oxygen exhaust device for medical hyperbaric oxygen chambers. Utility Model Content

[0005] The purpose of this invention is to provide an oxygen extraction device for a medical hyperbaric oxygen chamber to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oxygen exhaust device for a medical hyperbaric oxygen chamber, comprising a dust removal and sterilization chamber assembly, wherein an air inlet duct is provided on the outer wall of the dust removal and sterilization chamber assembly, an exhaust duct is provided on the outer wall of the dust removal and sterilization chamber assembly, a replacement positioning component is provided on the inner wall of the air inlet duct, the replacement positioning component comprises a bolt, the bolt being threadedly connected to the inner wall of the air inlet duct, a lifting block being threadedly connected to the outer wall of the bolt, a mounting plate being fixedly connected to the bottom end of the lifting block, a threaded hole being provided on the inner wall of the mounting plate, and a spring telescopic rod being rotatably mounted on the outer wall of the mounting plate; A movable plate is fixedly connected to the end of a spring telescopic rod. An anti-movement plug is fixedly connected to the outer wall of the movable plate. A handle is fixedly connected to the outer wall of the movable plate. A bolt is threadedly connected to the inner wall of the threaded hole two. A mounting bracket is provided on the outer wall of the bolt two. A filter screen is fixedly connected to the inner wall of the mounting bracket.

[0007] Preferably, the outer wall of the anti-moving insert is adapted to the outer wall of the second bolt, so that the anti-moving insert can be smoothly inserted into the second bolt.

[0008] Preferably, the mounting plate is slidably connected to the inner wall of the air intake duct, and the outer wall of the mounting plate is adapted to the inner wall of the air intake duct.

[0009] Preferably, the center line of the handle and the center line of the moving plate are on the same straight line.

[0010] Preferably, the outer wall of the air intake duct is provided with a limiting component, the limiting component including an extension positioning frame, the extension positioning frame being fixedly connected to the outer wall of the air intake duct, and the inner wall of the extension positioning frame having a limiting screw hole.

[0011] Preferably, the lifting block is slidably connected to the outer wall of the extension positioning frame, and the outer wall of the lifting block is adapted to the outer wall of the extension positioning frame.

[0012] Preferably, the centerline of the extended positioning frame and the centerline of the air intake duct are on the same plane.

[0013] Compared with the prior art, this utility model provides an oxygen extraction device for a medical hyperbaric oxygen chamber, which has the following beneficial effects: 1. The oxygen extraction device on this medical hyperbaric oxygen chamber has a new mounting bracket and filter installed below the mounting plate and fixed with bolt two. After fixing, the handle and moving plate can be pulled and the elastic telescopic rod rotated to align the anti-moving block with bolt two. Then the handle can be released, allowing the anti-moving block to be smoothly inserted into bolt two. Finally, the lifting block can be lifted to remove the mounting bracket and filter above the mounting plate. At this time, the mounting bracket and filter below will replace the mounting bracket and filter above for filtration, ensuring that there are new mounting brackets and filters for filtration and purification when installing and removing old mounting brackets and filters. The anti-moving block not only positions bolt two to prevent loosening, but also prevents dust and debris carried by the gas flow from entering the twist groove of bolt two after being inserted into bolt two, preventing the inability to insert the hex wrench into bolt two later.

[0014] 2. The oxygen extraction device on this medical hyperbaric oxygen chamber allows for the removal of the mounting bracket and filter screen above the mounting plate when the lifting block is raised. Bolt 1 can be re-fixed to the limiting screw hole on the extension positioning bracket, so that bolt 1 can re-fix the lifting block when it passes through the limiting screw hole. This makes it easier for operators to disassemble the mounting bracket and filter screen above, ensuring the convenience of filter screen replacement and further improving the overall practicality.

[0017] like Figures 1-7As shown, this utility model provides a technical solution: an oxygen exhaust device for a medical hyperbaric oxygen chamber, including a dust removal and sterilization box assembly 1. The dust removal and sterilization box assembly 1 can perform existing oxygen exhaust operations (reference: An independent oxygen exhaust device for a hyperbaric oxygen chamber - announcement number: CN223248456U). Through a gas storage component, it can temporarily store the gas in the hyperbaric oxygen chamber. Through a diversion component, it can evenly transport the gas discharged from the hyperbaric oxygen chamber to the dust removal mechanism. Simultaneously, the dust removal mechanism can remove dust from the transported gas, improving the practicality of the device. Through a connecting mechanism, it facilitates cleaning and replacement of the dust removal mechanism. Under the action of the gas dispersing mechanism, the gas after dust removal can be... The gas is widely discharged into the sterilization mechanism, and the sterilization mechanism can perform high-temperature sterilization on the discharged gas, which improves the practicality and versatility of the device. The outer wall of the dust removal and sterilization box group 1 is provided with an air inlet duct 2 and an exhaust duct 3. The inner wall of the air inlet duct 2 is provided with a replacement positioning component 4. The replacement positioning component 4 includes a bolt 401, which is threadedly connected to the inner wall of the air inlet duct 2. The outer wall of the bolt 401 is threadedly connected to a lifting block 402. The bottom end of the lifting block 402 is fixedly connected to a mounting plate 403. The inner wall of the mounting plate 403 has a threaded hole 404. The outer wall of the mounting plate 403 is rotatably mounted with a spring telescopic rod 405.

[0018] Furthermore, the movable plate 406 is fixedly connected to the end of the elastic telescopic rod 405. An anti-movement plug 407 is fixedly connected to the outer wall of the movable plate 406. A handle 408 is fixedly connected to the outer wall of the movable plate 406. A bolt 409 is threadedly connected to the inner wall of the threaded hole 404. A mounting bracket 410 is provided on the outer wall of the bolt 409. A filter screen 411 is fixedly connected to the inner wall of the mounting bracket 410.

[0019] In the embodiments of this utility model, the outer wall of the anti-moving insert 407 is adapted to the outer wall of the second bolt 409, so that the anti-moving insert 407 can be smoothly inserted into the second bolt 409. The mounting plate 403 is slidably connected to the inner wall of the air intake duct 2, and the outer wall of the mounting plate 403 is adapted to the inner wall of the air intake duct 2. The center line of the handle 408 and the center line of the moving plate 406 are on the same straight line.

[0020] Furthermore, the outer wall of the air intake duct 2 is provided with a limiting component 5, which includes an extension positioning frame 501. The extension positioning frame 501 is fixedly connected to the outer wall of the air intake duct 2. A limiting screw hole 502 is opened on the inner wall of the extension positioning frame 501. The lifting block 402 is slidably connected to the outer wall of the extension positioning frame 501, and the outer wall of the lifting block 402 is adapted to the outer wall of the extension positioning frame 501. The center line of the extension positioning frame 501 and the center line of the air intake duct 2 are both on the same plane.

[0021] In this invention, during daily use, the dust removal and sterilization box assembly 1 can perform existing oxygen desorption operations. The filter 411 in the air intake duct 2 can filter and purify the transported gas. When cleaning or replacing the filter 411 is required, bolt 401 can be removed. Then, a new mounting bracket 410 and filter 411 can be installed below the mounting plate 403 and fixed with bolt 409. After fixing, the handle 408 and the moving plate 406 can be pulled, and the elastic telescopic rod 405 can be rotated to align the anti-moving block 407 with bolt 409. Then, the handle 408 can be released, allowing the anti-moving block 407 to be smoothly inserted into bolt 409. Finally, the box can be lifted. The lifting block 402 removes the mounting bracket 410 and filter screen 411 above the mounting plate 403. At this time, the mounting bracket 410 and filter screen 411 below will replace the mounting bracket 410 and filter screen 411 above for filtration. This ensures that when installing or removing the old mounting bracket 410 and filter screen 411, there is always a new mounting bracket 410 and filter screen 411 for filtration and purification. The anti-movement insert 407 not only positions the bolt 2 409 to prevent loosening, but also prevents dust and debris that follow the air flow from entering the twist groove of the bolt 2 409 after it is inserted into the bolt 2 409. This prevents the hex wrench from being unable to be inserted into the bolt 2 409 later, ensuring the convenience of replacing the mounting bracket 410 and filter screen 411.

[0022] When lifting the lifting block 402 to remove the mounting bracket 410 and filter screen 411 above the mounting plate 403, bolt 401 can be re-fixed to the limiting screw hole 502 on the extension positioning bracket 501. This allows bolt 401 to re-fix the lifting block 402 when it passes through the limiting screw hole 502, making it easier for operators to disassemble the mounting bracket 410 and filter screen 411. This ensures the convenience of replacing the filter screen 411 and further enhances the overall practicality.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
