Ventilators occupy a very important position in the field of modern medicine.

[0003] As shown in the prior art published in CN221491135U, although this prior art uses a waterproof filter membrane to initially intercept and filter water vapor and atomized medicine, preventing water vapor and atomized medicine from directly contacting the filter element, and preventing particles in the medicine from adhering to the filter element, thus avoiding increased wetting of the filter element and clogging of the filter element's pores, the waterproof and breathable membrane in this prior art is placed vertically. This results in a larger contact area between the membrane and residues and water droplets, which affects the flow rate of residues and water droplets, making it easier for residues and water droplets to adhere to the surface of the waterproof and breathable membrane and cause clogging. Utility Model Content

[0004] To overcome the aforementioned deficiencies in the prior art, this utility model provides a nebulizer tubing filtration device. By setting the waterproof and breathable membrane in an inclined shape, residues and water vapor can more easily flow downwards along the surface of the waterproof and breathable membrane under the action of gravity. This reduces the adhesion and accumulation of residues and water droplets on the surface of the waterproof and breathable membrane, thereby effectively reducing the risk of clogging of the waterproof and breathable membrane and ensuring its performance, thus solving the problems mentioned in the background art.

[0010] In a preferred embodiment, the rear end of the connecting ring is provided with a connecting tube for connecting a medical filter. The front end of the connecting tube passes through the connecting ring and extends into the interior of the movable tube. The top and bottom of the front end of the connecting tube are provided with through holes. The front end of the connecting tube is in contact with the rear side of the mounting ring.

[0011] The mounting ring has a fixing ring on its front side, and the outside of the fixing ring is fixed to the inner wall of the movable tube.

[0012] In a preferred embodiment, a positioning ring is sleeved on the outer rear end of the connecting ring, and a ring plate is threadedly connected to the inner rear end of the positioning ring, the ring plate being sleeved on the outside of the connecting pipe;

[0013] A limiting ring groove is formed inside the front end of the positioning ring, and a limiting ring is provided inside the limiting ring groove. The limiting ring is sleeved on the outside of the rear end of the connecting ring.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Refer to the instruction manual appendix Figure 1-5 This utility model provides a nebulization and filtration device for a ventilator tubing, including a connecting tube 1 installed on a ventilator, a nebulization tube 2 fixedly connected to one side of the rear end of the connecting tube 1, the nebulization tube 2 being connected to a medical nebulizer for delivering nebulized medication, and an interceptor for filtering impurities on the other side of the rear end of the connecting tube 1.

[0028] The interceptor includes a branch pipe 3 that is fixedly connected to one side of the rear end of the connecting pipe 1. The rear end of the branch pipe 3 is rotatably connected to a movable pipe 4. An inclined mounting ring 5 is provided inside the movable pipe 4, and a waterproof and breathable membrane 6 is installed inside the mounting ring 5. Liquid holes 7 are provided on the top and bottom sides of the movable pipe 4 corresponding to the waterproof and breathable membrane 6.

[0029] In use, medical staff operate the connecting tube 12 to connect with the medical filter and rotate the positioning ring 15 to connect with the ring plate 16 by thread. This allows the connecting tube 12 to connect with the movable tube 4. The front end of the connecting tube 12 can limit the rear end of the mounting ring 5 to ensure the stability of the waterproof and breathable membrane 6 inside the mounting ring 5. After that, the medical staff install the connecting tube 1 on the ventilator and then operate the nebulizer tube 2 to connect with the medical nebulizer.

[0030] Thus, after the nebulized medicine is inhaled by the patient, the residual medicine and water vapor enter the active tube 4 through the connecting tube 1 and the branch tube 3. The water vapor and residual medicine are filtered by the waterproof and breathable membrane 6. The filtered air is then filtered a second time by a medical filter before returning to the ventilator. Because the waterproof and breathable membrane 6 is inclined, the residue and water vapor can more easily flow downward along the surface of the waterproof and breathable membrane 6 under the action of gravity. This reduces the adhesion and accumulation of residue and water droplets on the surface of the waterproof and breathable membrane 6, thereby effectively reducing the risk of the waterproof and breathable membrane 6 being blocked and ensuring the effectiveness of the waterproof and breathable membrane 6.

[0031] To prevent dripping residue and water droplets from scattering and polluting the environment, it is necessary to collect the residue and water droplets, such as... Figure 1-4 As shown, the movable tube 4 is fitted with a ring 19, and a flow guide frame 20 is installed at the bottom of the ring 19. A flow guide hole 21 is opened on the side of the bottom of the ring 19 corresponding to the flow guide frame 20. The flow guide hole 21 is connected to the liquid hole 7 located at the bottom of the movable tube 4. An installation hole 22 is opened at the bottom end of the flow guide frame 20. A collection bottle 23 is provided at the bottom end of the installation hole 22, and the top end of the collection bottle 23 extends into the installation hole 22. The top end of the collection bottle 23 is threaded to the inner wall of the installation hole 22. Through the threaded connection between the collection bottle 23 and the flow guide frame 20, the collection bottle 23 can correspond to the flow guide hole 21. Thus, when the residue and water droplets fall into the flow guide frame 20 through the liquid hole 7 and the flow guide hole 21, it is convenient for the collection bottle 23 to collect and store the residue and water droplets.

[0032] At the same time, to reduce the adhesion of residue and water droplets to the surface of the waterproof and breathable membrane 6, such as Figure 2-4As shown, the movable tube 4 has support rings 8 on both its front and rear ends, and the support ring 8 has an annular groove 9 inside the end closest to the movable tube 4. An assembly ring 10 is provided inside the annular groove 9 and is sleeved on the outside of the movable tube 4. The support ring 8 at the front end of the movable tube 4 is sleeved on the outside of the rear end of the branch tube 3, and a connecting ring 11 is installed inside the support ring 8 at the rear end of the movable tube 4. Because the movable tube 4 is connected to the assembly ring 10 through the annular groove 9 inside the support ring 8, medical staff can move the movable tube 4 to drive the waterproof and breathable membrane 6 to rotate. When the waterproof and breathable membrane 6 rotates, it can shake off the sticky residue and water droplets, thereby avoiding the accumulation of residue and water droplets and preventing blockage of the waterproof and breathable membrane 6. Moreover, the rotating waterproof and breathable membrane 6 can make more uniform contact with residue and water droplets, improving the filtration effect. This makes it easier for medical staff to perform auxiliary operations and improves the filtration performance of the waterproof and breathable membrane 6.

[0033] To prevent the waterproof and breathable membrane 6 from loosening and affecting the filtration effect, such as Figure 3 and 5 As shown, the connecting ring 11 has a connecting tube 12 for connecting a medical filter inside its rear end. The front end of the connecting tube 12 passes through the connecting ring 11 and extends into the movable tube 4. The top and bottom of the front end of the connecting tube 12 are provided with through holes 13. The front end of the connecting tube 12 is in contact with the rear side of the mounting ring 5. The mounting ring 5 has a fixing ring 14 on its front side. The outside of the fixing ring 14 is fixed to the inner wall of the movable tube 4. The fixing ring 14 supports the front side of the mounting ring 5, and the front end of the connecting tube 12 limits the rear side of the mounting ring 5, thereby fixing the waterproof and breathable membrane 6 and preventing the waterproof and breathable membrane 6 from becoming loose.

[0034] After prolonged use, the waterproof and breathable membrane 6 will wear out and need to be replaced. Therefore, a convenient replacement method is required for the waterproof and breathable membrane 6. A positioning ring 15 is sleeved on the outer rear end of the connecting ring 11, and a ring plate 16 is threadedly connected to the inner rear end of the positioning ring 15. The ring plate 16 is sleeved on the outer side of the connecting pipe 12. A limiting ring groove 18 is formed inside the front end of the positioning ring 15, and a limiting ring 17 is provided inside the limiting ring groove 18. The limiting ring 17 is sleeved on the outer rear end of the connecting ring 11. Medical staff can rotate the positioning ring 15 threadedly connected to the ring plate 16, thereby rotating and disassembling the connecting pipe 12 from the movable pipe 4, so that the rear side of the mounting ring 5 is not restricted, thus making it easy for medical staff to shake out the waterproof and breathable membrane 6 for convenient replacement.

[0035] To ensure the stability of active tube 4, such as Figure 1 , 2As shown in Figure 4, connecting frames 24 are installed on both the front and rear sides of the drainage frame 20. The top of the connecting frame 24 located on the front side of the drainage frame 20 is fixed to the bottom of the rear end of the branch pipe 3, and the top of the connecting frame 24 located on the rear side of the drainage frame 20 is fixed to the bottom of the connecting ring 11. The connecting frames 24 at both ends of the drainage frame 20 support the connecting ring 11 and the branch pipe 3 respectively, so that the drainage frame 20 and the connecting ring 11 can be connected to the branch pipe 3 as a whole, thereby ensuring the support of the drainage frame 20, the ring hoop 19 and the connecting ring 11 for the movable pipe 4 and ensuring the stability of the movable pipe 4.

[0036] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
