Description

Technical Field

[0001] The utility model relates to the technical field of gas leakage prevention, in particular to a medical oxygen gas leakage prevention device. Background Art

[0002] Medical oxygen uses cryogenic separation to separate oxygen from the atmosphere. After multiple compressions and cooling, it is then treated at -183°C to convert gaseous oxygen into liquid oxygen. It is repeatedly rectified and purified to remove dust and impurities, carbon monoxide, carbon dioxide, and water vapor, and then compressed and vaporized to directly fill oxygen cylinders. The national standard for the purity of bottled medical oxygen is ≥99.5%. The country has no prescribed medical oxygen standard for the oxygen produced by the oxygen concentrator. Regardless of whether the oxygen concentrator uses molecular sieve oxygen or oxygen-enriched membrane oxygen, the oxygen purity is lower than that of bottled medical oxygen. When using an oxygen concentrator to inhale oxygen, be sure to open the window for ventilation or connect the oxygen concentrator air collection pipe to the outdoors to take in air to increase the oxygen concentration.

[0003] In the existing technology, the storage of medical oxygen cylinders is a key part of medical gas management. However, in this process, gas leakage problems are often encountered due to aging or loosening of oxygen cylinder valves. These problems may be caused by various reasons such as wear and tear during daily use, aging of components due to long-term storage, or improper maintenance. Since there is no device that can promptly alarm or prompt staff in the event of gas leakage, it is easy to cause unnecessary waste of resources and affect the operating costs and efficiency of the hospital.

[0024] 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. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 5 The present invention provides a technical solution for a medical oxygen gas leakage prevention device:

[0026] In the embodiment of the present invention, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5The cam 308 is provided on the top of the cam 309 and the top of the cam 309 is provided with a first spring 307. The cam 308 is provided on the top of the cam 309 and the top of the cam 309 is provided with a second spring 307. The cam 308 is provided on the top of the cam 309 and the top of the cam 309 is provided with a first spring 307. The cam 308 is provided on the top of the cam 309 and the top of the cam 309 is provided with a first spring 307. The cam 308 is provided on the top of the cam 309 and the top of the cam 309 is provided with a first spring 307. The cam 308 is provided on the top of the cam 309 and the top of the cam 309 is provided with a first spring 307. The cam 308 is provided on the top of the cam 309 and the top of the cam 309 is provided with a first spring 307.

[0027] The cam 303 is provided with a plurality of support members 304, 305 and 306, which are provided with a plurality of support members 304. The support members 304 are provided with a plurality of support members 304 and 306, which are provided with a plurality of support members 304. The threshold value of the column 305 being deformed by pressure is higher than that of the first spring 307. This ensures that the telescopic column 305 is fixed and will not move before the first spring 307 is fully deformed. The first spring 307 provides space for the entire assembly to extend, can deform under the action of external force, and return to its original shape after the external force is removed. At the same time, the third push plate 308 is connected to the first spring 307. When the first spring 307 is displaced, it pushes the third push plate 308. A touch block 309 is installed at one end of the third push plate 308. The touch block 309 is used in conjunction with the paddle 310. When the third push plate 308 drives the touch block 309 and pushes the paddle 310, the paddle 310 turns on the lamp 5 and starts flashing, and causes the fixed block 6 at one end of the lamp 5 to sound an alarm. A remote control component is provided in the fixed block 6, which is connected to the staff's equipment. When the air pressure inside the sealing cover 2 increases, the remote control component in the fixed block 6 will trigger the staff's equipment and sound an alarm.

[0028] See Figure 2 、 Figure 4 As shown, a pressure reducing assembly 4 is installed at the top of the first push plate 304, and the pressure reducing assembly 4 includes an extension column 401 installed at the top of the first push plate 304, and two holes 402 are provided on the outer wall of the extension column 401. A space is provided inside the second push plate 306, and a second spring 404 is installed on the inner wall of the space, and a pressure block 403 is installed at one end of the second spring 404.

[0029] It should be noted that a ball block is provided at the front end of the pressure block 403. The ball block is used to provide a certain degree of sealing for the extension column 401, and because of the design of the shape of the ball block, the friction between the hole 402 and the pressure block 403 can be appropriately reduced. When the telescopic column 305 exceeds the threshold, the telescopic column 305 pushes and starts to move, and the extension column 401 installed on the first push plate 304 starts to move, allowing one end of the hole 402 to extend from the second push plate 306, and exhausting excess gas exceeding the pressure threshold from the hole 402, preventing the sealing cover 2 from exploding due to excessive pressure, causing property or casualties, thereby enhancing safety. Similarly, the second spring 404 deforms when subjected to force, and can also return to its original shape after the external force is removed.

[0030] Working principle: One side of the mounting block 301 is fixedly connected to the gas cylinder 1. The mounting block 301 is the base of the overall assembly. The material of the mounting block 301 is a rigid material. The mounting block 301 can provide sufficient stability and structural strength to ensure the integrity and functionality of the detection assembly 3. At the same time, a slider 302 is installed inside the mounting block 301. The slider 302 is slidably connected to the moving rod 303. At the same time, the extended part of the moving rod 303 is hollow, and the width of the hollow part is adapted to the slider 302. The design of the moving rod 303 is intended to reduce the amount of material used, thereby reducing the weight of the entire slider 302. The lightweight structure makes the slider 302 more sensitive to changes in air pressure and can better cooperate with other components to detect the gas cylinder 1. At the same time, due to the width adaptation, a compact motion transmission method is provided for the two. Installation in the mounting block 301 also ensures stability. The telescopic column 305 installed at one end of the first push plate 304 will not deform before being subjected to a certain pressure. The telescopic column 3 05 has a higher threshold for deformation under pressure than the first spring 307, which ensures that the telescopic column 305 is fixed and will not move before the first spring 307 is fully deformed. The first spring 307 provides space for the entire assembly to extend, can deform under the action of external force, and return to its original shape after the external force is removed. At the same time, the third push plate 308 is connected to the first spring 307. When the first spring 307 is displaced, it pushes the third push plate 308. A touch block 309 is installed at one end of the third push plate 308. The touch block 309 is used in conjunction with the paddle 310. When the third push plate 308 drives the touch block 309 and pushes the paddle 310, the paddle 310 turns on the lamp 5 and starts flashing, and causes the fixed block 6 at one end of the lamp 5 to sound an alarm. A remote control component is provided in the fixed block 6, which is connected to the staff's mobile device. When the air pressure inside the sealing cover 2 increases, the remote control component in the fixed block 6 will trigger the staff's device and sound an alarm.

[0031] A ball block is provided at the front end of the pressure block 403. The ball block is used to provide a certain degree of sealing for the extension column 401. Due to the design of the shape of the ball block, the friction between the hole 402 and the pressure block 403 can be appropriately reduced. When the telescopic column 305 exceeds the threshold, the telescopic column 305 pushes and starts to move, and the extension column 401 installed on the first push plate 304 starts to move, allowing one end of the hole 402 to extend from the second push plate 306, and exhausting excess gas exceeding the pressure threshold from the hole 402, preventing the sealing cover 2 from exploding due to excessive pressure, causing property or casualties, thereby enhancing safety. Similarly, the second spring 404 deforms when subjected to force, and can also return to its original shape after the external force is removed.
