Description

Technical Field

[0001] This utility model relates to the technical field of lung lavage equipment, specifically to a lung lavage device. Background Technology

[0002] Lung lavage is a key treatment for diseases such as pneumoconiosis, pulmonary alveolar proteinosis, aspiration pneumonia, severe or refractory lower respiratory tract infections, and status asthmaticus. It involves infusing the lungs with lavage fluids such as saline to flush out harmful substances and inflammatory secretions, thereby improving lung function. However, current lung lavage equipment on the market has many drawbacks.

[0003] Taking the patent application number CN202554581U as an example, the lung lavage and drainage device disclosed in this patent, while solving the drainage problem to some extent, suffers from poor stability of its oxygen tubing during the lavage operation in practical applications. It is prone to slippage, making it difficult to ensure the oxygen tubing remains precisely positioned throughout the lavage process. This may affect the stable delivery of oxygen and adversely impact the patient's respiratory support during lavage. Furthermore, the outlet structure of the flushing tube is relatively simple, and over time, it is prone to blockage by impurities. Blockage not only reduces lavage efficiency but may also lead to uneven lavage, failing to thoroughly remove harmful substances and inflammatory secretions from the lungs, thus affecting the treatment outcome. Utility Model Content

[0004] The purpose of this invention is to provide a lung lavage device to solve the problem mentioned in the background art that the oxygen tubing is not stable during the lavage operation, is prone to slippage, and is difficult to ensure that the oxygen tubing is always in a precise position throughout the lavage process. This may affect the stable delivery of oxygen and have an adverse effect on the patient's respiratory support during lavage.

[0005] To achieve the above objectives, this utility model provides a lung lavage device, including an infusion tube. The bottom of the infusion tube is connected to a flushing tube for rinsing with physiological saline. The connection between the infusion tube and the flushing tube is connected to a drain pipe for collecting flushing waste liquid via a T-connector. An oxygen tube for continuous oxygen delivery is also provided on one side of the flushing tube. The top of the oxygen tube is constrained and fixed to the flushing tube by a Y-shaped sleeve. The bottom of the Y-shaped sleeve is connected to a silicone sleeve that can wrap both the oxygen tube and the flushing tube.

[0006] This setup uses an IV tubing connected to a saline bag to deliver physiological saline solution, which is then used to flush the lungs via a flushing tubing. A three-way connector connects to an external drain pipe to collect the flushing wastewater, forming a complete irrigation cycle.

[0007] Preferably, the top of the infusion tube is connected to a saline bag for storing physiological saline, and a first tube clamp for opening and closing the tubing is installed on the top of the infusion tube.

[0008] This setting allows for convenient and quick control of the opening and closing of the infusion tubing, enabling medical staff to flexibly adjust the delivery of saline solution according to the irrigation process, ensuring the safety and controllability of the irrigation operation.

[0009] Preferably, the bottom of the sewage pipe is connected to a water collection tank for collecting wastewater, and the top of the sewage pipe is equipped with a second pipe clamp for opening and closing the pipe.

[0010] This setting controls the opening and closing of the drain pipe. When replacing the collection tank or when waste liquid is not required, the second pipe clamp is closed to prevent waste liquid leakage and ensure a clean and safe operating environment.

[0011] Preferably, a plurality of flushing fluid inlet and outlet ends are installed on the bottom outer wall of the flushing pipe, and the plurality of flushing fluid inlet and outlet ends are arranged at equal intervals on the outer wall of the flushing pipe.

[0012] Preferably, the inlet and outlet of the rinsing fluid has an outwardly convex arc-shaped structure, and the surface is provided with several small holes.

[0013] These two features allow the irrigation fluid to be distributed more evenly throughout the lungs, improving the comprehensiveness and uniformity of the lavage. This helps to more thoroughly remove harmful substances and inflammatory secretions from the lungs, enhancing treatment efficacy. Simultaneously, multiple small orifices disperse the pressure of the irrigation fluid, allowing it to act on the lung tissue more gently, improving lavage efficiency while reducing the possibility of damage to lung tissue.

[0014] Preferably, the bottom end of the oxygen tube is equipped with a spherical outlet end, and the surface of the outlet end is evenly provided with a plurality of outlet holes.

[0015] This spherical structure allows oxygen to be output evenly from multiple directions, avoiding the impact of concentrated oxygen injection on the lungs.

[0016] Preferably, the Y-shaped sleeve has a Y-shaped structure, with the flushing tube inserted from one side of the top of the Y-shaped sleeve and the oxygen tube inserted from the other side of the top of the Y-shaped sleeve, and the ends of both the flushing tube and the oxygen tube exiting from the bottom of the Y-shaped sleeve.

[0017] This setup achieves the orderly integration and fixation of the two pipelines, providing good constraint and positioning for the oxygen and flushing pipes, preventing relative displacement during the rinsing process, and ensuring the stability of rinsing and oxygen delivery operations.

[0018] Preferably, the Y-shaped sleeve is equipped with an adjustment part on the side near the oxygen tube, which can adjust the movement or positioning of the oxygen tube. The adjustment part includes a rotating wheel, the axis of which is rotatably connected to the inner wall of the Y-shaped sleeve via a rotating shaft. A tube groove is formed on the circumferential side of the rotating wheel. The inner wall of the tube groove is an outwardly convex arc-shaped structure made of silicone material, and the oxygen tube is stuck on the inner wall of the tube groove.

[0019] This feature allows for flexible adjustment of the oxygen tube's movement or positioning by rotating a wheel around a shaft and engaging with the silicone arc-shaped structure on the inner wall of the tube groove.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In this lung lavage device, the oxygen tube and the rinsing tube are constrained and fixed by the Y-shaped sleeve and the silicone sleeve. The adjustment part on one side of the Y-shaped sleeve can adjust the movement or positioning of the oxygen tube. The silicone arc surface structure on the inner wall of the tube groove on the rotating wheel can firmly hold the oxygen tube, preventing the oxygen tube from sliding during the lavage operation, ensuring stable oxygen delivery, and providing reliable respiratory support for the patient during lavage.

[0022] The flushing fluid inlet and outlet at the bottom of the flushing tube has an outwardly convex arc-shaped structure with several small holes on the surface. Compared with a single outlet structure, this reduces the risk of impurities clogging the lungs and improves the flushing efficiency. The multiple flushing fluid inlets and outlets are arranged at equal intervals, which allows the flushing fluid to flush the lungs more evenly, helping to thoroughly remove harmful substances and inflammatory secretions from the lungs and improve the treatment effect.

[0028] 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.

[0029] This utility model provides a lung lavage device, such as... Figure 1 As shown, it includes an infusion tube 1, the bottom of which is connected to a flushing tube 2 for rinsing with physiological saline. The connection between the infusion tube 1 and the flushing tube 2 is connected to a drain pipe 3 for collecting flushing waste liquid via a T-connector 5. An oxygen tube 6 for continuous oxygen delivery is also provided on one side of the flushing tube 2. The top of the oxygen tube 6 is constrained and fixed to the flushing tube 2 by a Y-shaped sleeve 7. The bottom of the Y-shaped sleeve 7 is connected to a silicone sleeve 8 that can wrap the oxygen tube 6 and the flushing tube 2 together.

[0030] During use, saline bag 4 is connected to infusion tube 1 to deliver physiological saline, and the lungs are flushed through flushing tube 2. The three-way connector 5 is connected to the external sewage pipe 3 to collect the flushing waste liquid, forming a complete irrigation cycle. Oxygen tube 6 and flushing tube 2 are constrained and fixed by Y-shaped sleeve 7 and silicone sleeve 8 to ensure that the position of oxygen tube 6 is stable during irrigation, so as to provide continuous and stable oxygen delivery to support the patient's breathing. At the same time, each pipeline has a clear division of labor to ensure that the irrigation operation is carried out in an orderly manner.

[0031] In this embodiment, as Figure 1 As shown, the top of the infusion tube 1 is connected to a saline bag 4 for storing physiological saline, and a first clamp 11 for opening and closing the tubing is installed on the top of the infusion tube 1. The saline bag 4 connected to the top of the infusion tube 1 allows for the storage of a large amount of physiological saline to meet irrigation needs; the first clamp 11, installed on the infusion tube 1, enables convenient and quick control of the opening and closing of the infusion tube 1, facilitating medical personnel to flexibly adjust the delivery of physiological saline according to the irrigation process, ensuring the safety and controllability of the irrigation operation.

[0032] Specifically, such as Figure 1 As shown, the bottom of the drain pipe 3 is connected to a collection tank 32 for wastewater collection, and a second clamp 31 for opening and closing the pipe is installed on the top of the drain pipe 3. The height of the collection tank 32 is lower than the lower end of the flushing pipe 2, thus forming a siphon to facilitate the drainage of fluid from the lungs. The collection tank 32 connected to the bottom of the drain pipe 3 is used to collect the waste fluid generated during lung lavage, preventing indiscriminate discharge and pollution. The second clamp 31 is installed on the drain pipe 3 to control the opening and closing of the drain pipe 3. When replacing the collection tank 32 or when waste fluid is not required, the second clamp 31 is closed to prevent waste fluid leakage and ensure a clean and safe operating environment.

[0033] Furthermore, such as Figure 1 As shown, several flushing fluid inlet and outlet ends 21 are installed on the bottom outer wall of the flushing tube 2. The flushing fluid inlet and outlet ends 21 are arranged at equal intervals on the outer wall of the flushing tube 2, which increases the contact area between the flushing fluid and the lungs, so that the flushing fluid can be more evenly distributed to various areas of the lungs, improving the comprehensiveness and uniformity of irrigation, helping to more thoroughly remove harmful substances and inflammatory secretions from the lungs, and improving the treatment effect.

[0034] Furthermore, such as Figure 1 As shown, the inlet and outlet of the rinsing fluid 21 has an outwardly convex arc-shaped structure with several small holes on its surface. Compared with a single flat outlet, this structural design can effectively reduce the risk of impurities adhering and clogging, ensuring smooth flow of rinsing fluid. At the same time, the multiple small holes disperse the pressure of the rinsing fluid, allowing the rinsing fluid to act on the lung tissue in a gentler manner, improving irrigation efficiency while reducing the possibility of damage to lung tissue.

[0035] Furthermore, such as Figure 1 As shown, the bottom end of the oxygen tube 6 is equipped with a spherical outlet end 61, and the surface of the outlet end 61 is evenly provided with several outlet holes. This spherical structure enables oxygen to be output evenly from multiple directions, avoiding concentrated oxygen injection that could impact the lungs; moreover, the evenly distributed outlet holes ensure the stability and uniformity of oxygen output, providing patients with a more comfortable and stable oxygen supply, and helping to maintain stable breathing during the lavage process.

[0036] Furthermore, such as Figure 1 , Figure 2 As shown, the Y-shaped sleeve 7 has a Y-shaped structure. The flushing pipe 2 enters from one side of the top of the Y-shaped sleeve 7, and the oxygen pipe 6 enters from the other side of the top of the Y-shaped sleeve 7. The ends of both the flushing pipe 2 and the oxygen pipe 6 exit from the bottom of the Y-shaped sleeve 7. Through the unique Y-shaped structure, the flushing pipe 2 and the oxygen pipe 6 enter from the top sides respectively and exit from the bottom together, realizing the orderly integration and fixation of the two pipes. This provides good constraint and positioning for the oxygen pipe 6 and the flushing pipe 2, preventing relative displacement between the two during the rinsing process and ensuring the stability of the rinsing and oxygen delivery operations.

[0037] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown, an adjustment part 9 is installed on the side of the Y-shaped sleeve 7 near the oxygen tube 6, which can adjust the movement or positioning of the oxygen tube 6. The adjustment part 9 includes a rotating wheel 91. The axis of the rotating wheel 91 is rotatably connected to the inner wall of the Y-shaped sleeve 7 through a rotating shaft 92. A tube groove 93 is opened on the circumferential side of the rotating wheel 91. The inner wall of the tube groove 93 is an arc-shaped structure that is convex outward and made of silicone material. The oxygen tube 6 is stuck on the inner wall of the tube groove 93. One side of the rotating wheel 91 rotates and extends through to the outside of the Y-shaped sleeve 7.

[0038] The oxygen tube 6 is held in place by the silicone arc-shaped structure on the inner wall of the tube groove 93, allowing for flexible adjustment of its movement and positioning. When the position of the oxygen tube 6 needs to be adjusted, rotating the wheel 91 causes the oxygen tube 6 to slide within the Y-shaped sleeve 7, thereby adjusting the position of the outlet end 61 within the body. When the wheel 91 is not rotated, it presses against the outer wall of the oxygen tube 6, thus securing it and ensuring that the oxygen tube 6 remains in a precise position throughout the rinsing process. This guarantees stable oxygen delivery and improves the flexibility and reliability of the equipment.

[0039] When using the lung lavage device of this utility model, firstly, before using the lung lavage device, connect the top of the infusion tube 1 to the saline bag 4 storing physiological saline, and connect the bottom of the drain tube 3 to the water collection tank 32, ensuring that all pipes are tightly connected. At the same time, by adjusting the adjusting part 9 on the Y-shaped sleeve 7, according to the actual condition of the patient's lungs, the oxygen tube 6 is slid by rotating the rotating wheel 91 to adjust the air outlet 61 to a suitable position; when the rotating wheel 91 is not rotated, the oxygen tube 6 is locked and fixed, ensuring the precise positioning of the oxygen tube 6 during the lavage process. Then, the oxygen tube 6 is constrained and fixed to the flushing tube 2 using the Y-shaped sleeve 7 and the silicone sleeve 8.

[0040] After preparation, open the first clamp 11. Normal saline solution flows from the saline bag 4 through the infusion tube 1 into the flushing tube 2. Because the bottom of the flushing tube 2 has multiple equally spaced flushing fluid inlet / outlet terminals 21, and these terminals have a convex arc-shaped structure with several small holes, the normal saline solution will be evenly sprayed into the lungs through these holes to flush them. During flushing, the flushed waste fluid enters the flushing tube 2 through the flushing fluid inlet / outlet terminals 21, then flows through the three-way connector 5 into the drain pipe 3, and is finally collected in the collection tank 32. Medical staff can control the opening and closing of the drain pipe 3 using the second clamp 31 as needed. When the collection tank 32 is almost full or when waste fluid discharge is not required, the second clamp 31 is closed to prevent waste fluid leakage.

[0041] Meanwhile, the evenly distributed air outlet holes on the surface of the spherical outlet end 61 at the bottom of the oxygen tube 6 continuously deliver oxygen to the lungs. Throughout the lavage process, the Y-shaped sleeve 7, the silicone sleeve 8, and the adjustment unit 9 work together to keep the oxygen tube 6 in a stable position, ensuring a stable and uniform output of oxygen, providing continuous respiratory support for the patient, maintaining stable breathing during the lavage process, and ensuring that the lavage operation is carried out safely, orderly, and efficiently until the lung lavage treatment is completed.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
