Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of lung lavage equipment, specifically to a multi-channel lung lavage assembly. Background Technology
[0002] In the medical field, pulmonary lavage is an important treatment for various lung diseases, such as alveolitis, pulmonary fibrosis, asbestosis, lung cancer, Pneumocystis jirovecii disease, and pulmonary alveolar proteinosis. This technique involves injecting physiological saline into the bronchi and alveoli and then immediately aspirating it to collect the effective fluid from the alveolar surface. This fluid is used for clinical diagnosis, differential diagnosis, and research on the etiology, pathogenesis, efficacy evaluation, and prognosis of lung diseases.
[0003] Currently used clinical lung lavage equipment and tubing components have certain limitations. For example, existing tubing is mostly single-channel, only allowing for the injection of lavage fluid. During bronchoscopy and related procedures, if the patient uses a nasal cannula for oxygen, the low oxygen flow can easily lead to hypoxia and cyanosis. Furthermore, when inserting tools such as brushes, cuffs, or biopsy forceps, the single-channel design requires repeated insertion and removal of the lavage fluid tubing, making the surgical procedure cumbersome and hindering the reduction of surgical time. Another example is the multi-channel alveolar lavage connector disclosed in patent application number CN202321797963. While it achieves multi-channel flow, allowing simultaneous introduction of oxygen and lavage fluid to prevent cyanosis and facilitating the insertion of surgical instruments when lavage fluid injection stops, it still cannot simultaneously lavage different parts of the lung lobes, making it difficult to improve lavage efficiency or provide precise and efficient lavage treatment for different lesions in the lungs. Therefore, the development of a multi-channel lung lavage assembly is needed to address these issues. Utility Model Content
[0004] The purpose of this invention is to provide a multi-channel lung lavage assembly to solve the problems mentioned in the background art, which make it difficult to simultaneously lavage different parts of the lung lobes, thus failing to improve lavage efficiency and to provide precise and efficient lavage treatment for different lesions in the lungs.
[0005] To achieve the above objectives, this utility model provides a multi-channel lung lavage assembly, including a cannula. The cannula contains several lavage branches for simultaneous lavage of different parts of the lung lobes. The cannula is equipped with a channel adjustment component that allows for independent opening and closing of the different lavage branches. Clamping components are installed on the outer side of the channel adjustment component in different directions. The end of each clamping component abuts against a corresponding lavage branch. Adjusting the movement of the clamping components allows for the opening and closing of the lavage channel of the lavage branch.
[0006] This setting allows for flexible adjustment of the irrigation status of each bronchus during the irrigation process, based on the actual condition of different parts of the lungs. For example, irrigation can be intensified in severely diseased areas, while irrigation can be reduced or suspended in normal or more sensitive areas, thus achieving precise irrigation and improving the irrigation effect and safety.
[0007] Preferably, the sleeve has a support block inside, and the support block has a number of grooves on its outer side. The number of grooves is the same as the number of irrigation branch pipes, and the irrigation branch pipes are locked inside the grooves for positioning.
[0008] Preferably, the outer wall of the support block is bonded and fixed to the inner wall of the sleeve.
[0009] These two features ensure that the irrigation tubing stably delivers the rinsing fluid to the intended location in the lungs during irrigation, guaranteeing the accuracy and stability of the procedure and preventing poor irrigation results or lung tissue damage due to tubing displacement. Simultaneously, the adhesive fixation method avoids creating excessively complex structures within the tubing, minimizing interference with the flow of the irrigation fluid and ensuring a smooth irrigation process.
[0010] Preferably, the channel adjustment assembly includes a housing, the inside of which is provided with a pipeline channel, which is sleeved on the outside of the sleeve. The outer wall of the housing has multiple mounting holes that communicate with the inside of the pipeline channel, and the clamping assembly is installed in the mounting holes.
[0011] This feature allows the clamping assembly to precisely engage with the irrigation branch pipe, enabling effective control of the irrigation channel and ensuring the stable operation of the overall channel adjustment assembly.
[0012] Preferably, the clamping assembly includes a fixing plate, the outer wall of which is bonded to the inner wall of the mounting hole, a threaded hole is provided in the middle of the fixing plate, a threaded rod is threaded into the threaded hole, and a pressure head made of silicone material is installed at one end of the threaded rod near the irrigation branch pipe.
[0013] Preferably, a knob is installed at the end of the threaded rod away from the irrigation branch pipe.
[0014] This feature allows for easy rotation of the threaded rod via a rotating knob, enabling the opening and closing of the flushing channels in the flushing branch pipes without the need for other complex tools. This significantly improves the convenience and efficiency of operation, allowing operators to quickly and accurately adjust the working status of each flushing branch pipe.
[0015] Preferably, the outer shell is a cuboid or cylindrical structure.
[0016] This design, featuring both shapes, is characterized by its simple structure and ease of processing, thus reducing production costs. Furthermore, its regular shape facilitates handling and storage in scenarios such as surgical procedures.
[0017] Preferably, the bottom of the irrigation branch pipe extends to the outside of the bottom of the sleeve and is equipped with a flushing end. The flushing end has a spherical structure and several through holes on its surface. The tops of multiple irrigation branch pipes are connected to a flushing pump through a common connection end.
[0018] This setting allows the rinsing fluid to be sprayed evenly from multiple directions, expanding the rinsing range and improving the comprehensiveness and uniformity of irrigation, ensuring that all parts of the lungs are fully and effectively irrigated.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] In this multi-channel lung lavage assembly, several lavage branches installed within the cannula can simultaneously lavage different parts of the lung lobes. Compared with traditional single-channel or limited-channel lavage methods, this greatly improves lavage efficiency, shortens treatment time, and enables simultaneous lavage treatment for different lesion sites in the lungs, achieving precision medicine and improving treatment outcomes.
[0021] The inclusion of channel adjustment and clamping components allows medical staff to independently adjust the opening and closing of different irrigation tubes. Rotating the knob moves the threaded rod, applying or releasing pressure to the irrigation tube with the pressure head, thus controlling the opening and closing of the irrigation channel. This function allows for flexible adjustment of the irrigation operation for each tube according to the specific condition of the patient's lungs; for example, increasing the irrigation intensity for severely diseased areas and reducing unnecessary irrigation for relatively healthy areas, improving the flexibility and targeted nature of the operation.
[0022] The support blocks and grooves inside the cannula limit the movement of each irrigation branch, preventing it from shaking or shifting within the cannula and ensuring stability during the irrigation process. The outer wall of the support block is bonded to the inner wall of the cannula, further enhancing the overall structural stability and reducing patient discomfort or operational errors that may be caused by tubing movement.

[0029] 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.
[0030] This invention provides a multi-channel lung lavage assembly, such as... Figures 1-2 As shown, the system includes a cannula 1, within which several irrigation branches 3 are installed for simultaneous irrigation of different parts of the lung lobes. A channel adjustment component 2 is mounted on the cannula 1 to independently open and close the different irrigation branches 3. Compression components 23 are installed on the outer side of the channel adjustment component 2 in different directions. The end of each compression component 23 abuts against a corresponding irrigation branch 3. Adjusting the movement of the compression component 23 opens or closes the irrigation channel of the irrigation branch 3. The cannula 1 is a flexible tube that can be deformed by the end of the compression component 23, thereby compressing and pressing against the irrigation branch 3 to close the irrigation channel.
[0031] In use, the cannula 1 serves as the main body of the overall structure. Several irrigation branches 3 are internally installed, enabling simultaneous irrigation of different parts of the lung lobes, significantly improving irrigation efficiency and avoiding time wastage and potential infection risks associated with sequential irrigation. The channel adjustment component 2 is installed on the cannula 1, with its outer clamping component 23 engaging with the irrigation branches 3. By adjusting the movement of the clamping component 23, the opening and closing of each irrigation branch 3's irrigation channel can be independently controlled. This allows for flexible adjustment of the irrigation status of each branch according to the actual condition of different parts of the lung during irrigation. For example, irrigation can be intensified in severely diseased areas, while irrigation can be reduced or suspended in normal or more sensitive areas, achieving precise irrigation and improving both the irrigation effect and safety.
[0032] In this embodiment, as Figure 1 , Figure 2 , Figure 3As shown, the sleeve 1 has a support block 11 inside, and the support block 11 has several grooves 12 on its outer side. The number of grooves 12 is the same as the number of irrigation branch tubes 3. The irrigation branch tubes 3 are locked inside the grooves 12 for positioning. This structure can effectively fix the position of each irrigation branch tube 3, preventing the irrigation branch tubes 3 from moving or shaking freely inside the sleeve 1. This ensures that the irrigation branch tubes 3 stably deliver the rinsing fluid to the predetermined site in the lungs during the irrigation process, ensuring the accuracy and stability of the irrigation operation and avoiding poor irrigation effect or damage to lung tissue due to branch tube displacement.
[0033] Specifically, the outer wall of the support block 11 is bonded and fixed to the inner wall of the sleeve 1. This connection method is simple and reliable, ensuring that the support block 11 is stably installed inside the sleeve 1, thereby providing a stable support and limiting foundation for multiple irrigation branch pipes 3. At the same time, the bonding and fixing method does not form too many complex structures inside the sleeve 1, reducing interference with the flow of irrigation fluid and ensuring the smoothness of the irrigation process.
[0034] Furthermore, such as Figure 1 , Figure 2 As shown, the channel adjustment component 2 includes a housing 21, inside which is provided a pipeline channel 211. The pipeline channel 211 is sleeved on the outside of the sleeve 1. The outer wall of the housing 21 has multiple mounting holes 22, which are connected to the inside of the pipeline channel 211. The clamping component 23 is installed in the mounting holes 22.
[0035] The channel regulating component 2 has a pipeline channel 211 inside its outer casing 21 to accommodate the sleeve 1 and the irrigation branch pipe 3, protecting and organizing the pipelines and preventing them from becoming tangled or damaged. The mounting holes 22 on the side wall of the outer casing 21 provide accurate position and space for the installation of the clamping component 23, allowing it to precisely engage with the irrigation branch pipe 3, effectively controlling the irrigation channel and ensuring the stable operation of the channel regulating component 2.
[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown, the clamping assembly 23 includes a fixing plate 221. The outer wall of the fixing plate 221 is bonded and fixed to the inner wall of the mounting hole 22. A threaded hole 2211 is provided in the middle of the fixing plate 221. A threaded rod 222 is connected to the threaded hole 2211. A pressure head 223 made of silicone material is rotatably installed at one end of the threaded rod 222 near the irrigation branch pipe 3.
[0037] The fixing plate 221 is bonded to the outer side of the mounting hole 22 to ensure a stable installation on the outer shell 21, providing stable support for components such as the threaded rod 222. The threaded rod 222 can be moved axially by rotating it. The silicone pressure head 223 installed near the end of the threaded rod 222 close to the irrigation branch pipe 3 has good flexibility and sealing properties. When the threaded rod 222 is rotated to press the pressure head 223 against the irrigation branch pipe 3, it can effectively close the irrigation channel; rotating it in the opposite direction opens the channel. This structure is simple to operate and precise to adjust, allowing for flexible control of the opening and closing state of the irrigation branch pipe 3 according to actual needs. Furthermore, the silicone pressure head 223 will not cause hard damage to the irrigation branch pipe 3, ensuring its service life.
[0038] Furthermore, the knob 224 installed at the end of the threaded rod 222 away from the irrigation branch pipe 3 provides a convenient point of force application for the operator. By rotating the knob 224, the threaded rod 222 can be easily rotated, thereby realizing the opening and closing adjustment of the irrigation channel of the irrigation branch pipe 3 without the need for other complicated tools, which greatly improves the convenience and efficiency of operation, allowing the operator to quickly and accurately adjust the working status of each irrigation branch pipe 3.
[0039] Furthermore, the outer shell 21 has a cuboid or cylindrical structure. These two shapes are simple in structure and easy to process, which can reduce production costs. At the same time, the cuboid or cylindrical structure has good adaptability and stability when installed with the sleeve 1 and other components, which facilitates the assembly and use of the overall assembly. Moreover, its regular shape is also beneficial for operation and storage in scenarios such as surgical procedures.
[0040] Furthermore, such as Figure 1 As shown, the bottom of the irrigation branch pipe 3 extends to the outside of the bottom of the sleeve 1 and is equipped with a flushing end 31. The flushing end 31 has a spherical structure and several through holes on its surface. The tops of multiple irrigation branch pipes 3 are connected to an external flushing pump through a connecting end 32.
[0041] By creating several through-holes on the surface of the spherical flushing end 31 at the bottom of the irrigation branch tube 3, this design allows the flushing fluid to be sprayed evenly from multiple directions, expanding the flushing range and improving the comprehensiveness and uniformity of the irrigation, ensuring that all parts of the lungs receive adequate and effective irrigation. An external flushing pump is connected to the top connection end 32 of the multiple irrigation branch tubes 3, providing a stable power source for the irrigation process and ensuring that the flushing fluid can be continuously and stably delivered to the lungs, meeting the flow and pressure requirements of the irrigation operation.
[0042] When using the lung lavage multi-channel assembly of this utility model, the support block 11 is first fixed inside the sleeve 1 by adhesive bonding to ensure that the outer wall of the support block 11 is tightly fitted with the inner wall of the sleeve 1, providing a stable foundation for the subsequent installation of the lavage branch tube 3.
[0043] Next, multiple irrigation branch pipes 3 are sequentially inserted into the corresponding grooves 12 on the outside of the support block 11. The grooves 12 limit the irrigation branch pipes 3, keeping them in a fixed position within the sleeve 1 to prevent movement or shaking. Then, the outer shell 21 is installed on the sleeve 1, aligning the pipeline channel 211 of the outer shell 21 with the position of the irrigation branch pipe 3, and the irrigation branch pipe 3 is inserted into the pipeline channel 211, achieving protection and organization of the irrigation branch pipe 3. Afterward, the clamping assembly 23 is installed in the mounting hole 22 on the side wall of the outer shell 21, and the outer wall of the fixing plate 221 is bonded and fixed to the inner wall of the mounting hole 22. Finally, the connecting end 32 of the irrigation branch pipe 3 is connected to the flushing pump, ensuring a tight connection to provide power for the irrigation process.
[0044] During the procedure, the cannula 1 and its internal irrigation branch tube 3 are inserted into the lungs of the patient to be irrigated. Depending on the specific location of the lung, the clamping component 23 is controlled by rotating the knob 224. Rotating the knob 224 clockwise moves the threaded rod 222 along the threaded hole 2211 towards the irrigation branch tube 3, causing the silicone pressure head 223 to gradually press against the irrigation branch tube 3, thereby closing the irrigation channel of the corresponding branch tube 3 and reducing or stopping irrigation of that branch tube. If irrigation of a specific area is required, rotating the knob 224 counterclockwise moves the threaded rod 222 away from the irrigation branch tube 3, opening the irrigation channel. This method allows for flexible adjustment of the irrigation status of each irrigation branch tube 3, achieving precise irrigation.
[0045] After the flushing pump is started, the flushing fluid enters the irrigation branch pipe 3 through the connection end 32 and is evenly sprayed out from the through hole on the surface of the spherical flushing end 31 at the bottom of the irrigation branch pipe 3 to flush the corresponding parts of the lungs. The spherical structure and multi-hole design can expand the flushing range and ensure that all parts of the lungs are fully and effectively flushed.
[0046] After flushing, first turn off the flushing pump to stop the flushing fluid delivery. Then, disconnect the connection end 32 of the flushing branch pipe 3 from the flushing pump. If it is necessary to disassemble the components for cleaning and disinfection, first remove the clamping component 23 from the mounting hole 22 of the housing 21, then remove the housing 21 of the channel adjusting component 2 from the sleeve 1, then remove the flushing branch pipe 3 from the groove 12 of the support block 11, and finally perform a thorough cleaning and disinfection of the support block 11, the channel adjusting component 2, and the clamping component 23 for future use.

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.
