Technical Field
[0001] This utility model belongs to the field of medical consumables technology, specifically relating to a disposable visual bronchoalveolar lavage fluid collection tube. Background Technology
[0002] Bronchoalveolar lavage fluid (BALF) collection is an important means of diagnosing lung diseases. BALF is collected at different stages using a BALF collection tube for cytological examination, microbial culture, or other related tests. The collection process involves inserting a bronchoscope into the patient's airway under anesthesia, using a bronchoscope and other medical equipment to reach the predetermined lavage site. Warm, sterile saline solution is injected into the airway through the biopsy port of the bronchoscope. The injected lavage fluid is then collected using a negative pressure suction collector and the lavage fluid collection tube. The lavage fluid collection tube is a commonly used medical consumable.
[0003] During the use of the aforementioned negative pressure suction collector and irrigation fluid collection tube, one end of the irrigation fluid collection tube is connected to the negative pressure suction collector via a plug-in or spiral connection. The irrigation fluid collection tube also has a certain length. During the collection process, one end of the irrigation fluid collection tube is soft. If the negative pressure suction collector moves or the irrigation fluid collection tube shakes, the connection of the irrigation fluid collection tube may not be tight, resulting in leakage. This indicates that the connection at one end of the irrigation fluid collection tube is unstable.
[0004] When existing lavage fluid collection tubes are used in conjunction with negative pressure suction collectors, one end of the lavage fluid collection tube is soft and there is no reinforcement design to increase the stability of the connection. Therefore, this application proposes a disposable visual alveolar lavage fluid collection tube. Utility Model Content

[0024] 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.
[0025] Please see Figures 1 to 4This utility model provides a technical solution: a disposable visual alveolar lavage fluid collection tube, including an alveolar lavage fluid collection assembly connected to the annular interface a at the top of the lavage fluid collector 11 via a threaded connection, comprising a fixed cap 12 connected to the lavage fluid collector 11, a one-way valve 13 communicating with the fixed cap 12, a first pipe 14 communicating with the other end of the one-way valve 13, a regulating valve 15 connected to the first pipe 14, and an lavage fluid collection and delivery pipe 16 connected to the other side of the regulating valve 15. An inlet hole 161 is provided on the surface of the end of the collection and delivery pipe 16, allowing the irrigation fluid to enter the interior of the collection and delivery pipe 16 through the inlet hole 161. The fixing cap 12 is connected to the annular interface a of the irrigation fluid collector 11 by a threaded connection. The fixing cap 12 ensures a rigid connection between one end of the collection and delivery pipe 16 and the irrigation fluid collector 11, preventing leakage. The one-way valve 13 prevents backflow. The visible component includes the fixedly connected collection and delivery pipe. The lavage fluid collection and delivery tube 16 includes an internal light source camera 23, a data cable 21 located inside the tube and connected to the light source camera 23 at one end, and a data interface 22 fixedly connected to the other end of the data cable 21 that extends out of the tube. The working principle of the light source camera 23 is mainly based on the reflection and reception of infrared light. When the infrared light source emits infrared light, the infrared light will illuminate the monitored object and reflect back. The camera receives the reflected infrared light through its lens and converts it into an electrical signal for processing and storage. The light source camera 23 is a conventional camera device, which will not be described in detail in this application. The lavage fluid collection and delivery tube 16 is made of transparent medical plastic material. During the delivery of lavage fluid, it has the function of visualizing the color of the lavage fluid. The data interface 22 is connected to other medical devices to process the electrical signal generated by the light source camera 23 to achieve the effect of visualizing the alveolar lavage fluid. A rotating ring 3 is rotated on the outside of the fixed cover 12. The rotating ring 3 can rotate to facilitate changing the angle of the clamping components.The clamping assembly includes a fixed plate 4 fixedly connected to the rotating ring 3, a lifting rod 6 slidably connected to the inner wall of the fixed plate 4, and a clamping plate 5 rotatably connected to one end of the lifting rod 6. The fixed plate 4 is provided with a pressing assembly, which includes a pressing rod 41 slidably connected to the fixed plate 4, pressing blocks 42 distributed within the fixed plate 4 and fixedly connected to one end of the pressing rod 41, and a compression spring 43 installed between opposing pressing blocks 42. A stabilizing plate 421 is provided on the pressing block 42, and the stabilizing plate 421 is fixedly connected to the pressing block 42. The fixed plate 4 has a limiting plate 7 fixedly connected to one end of the lifting rod 6 inside. A protrusion 71 is fixedly connected to the inner surface of the opposing plate 7. The protrusion 71 is embedded in the interior of the stabilizing plate 421, thereby limiting the positioning plate 7, the lifting rod 6, and the clamping plate 5. The clamping plate 5 and the fixing plate 4 can clamp the bed board or bed board frame on the side of the bed, thereby fixing the fixing cover 12 and the irrigation fluid collector 11, preventing the fixing cover 12 and the irrigation fluid collector 11 from moving, which would cause the end of the irrigation fluid collection and delivery tube 16 to be in a shaky state and thus leak. The lifting rod 6 is slidably connected to the fixing plate 4, which can change the distance between the clamping plate 5 and the fixing plate 4 to accommodate bed boards or bed board frames of different thicknesses.
[0026] In this embodiment, a bronchoalveolar lavage fluid collection path is also included, which consists of an lavage fluid collection and delivery pipe 16, a regulating valve 15, a first pipe 14, a one-way valve 13, a fixed cover 12, and an lavage fluid collector 11. The lavage fluid collection and delivery pipe 16 collects lavage fluid into the lavage fluid collector 11.
[0027] In this embodiment, the end of the pressing rod 41 exposed on the outside of the fixing plate 4 is a "T" shaped structure. The squeezing block 42 is provided with a concave circular groove that matches one end of the contraction spring 43. The squeezing block 42 restricts the contraction spring 43 and prevents the contraction spring 43 from tilting.
[0028] In this embodiment, the rectangular stabilizing plate 421 is provided with a concave rectangular groove that corresponds to and matches the protrusion 71. The protrusion 71 is engaged with the stabilizing plate 421, which can limit the protrusion 71 and thus fix the limiting plate 7.
[0029] In this embodiment, the protrusion 71 is a "U"-shaped structure with right angles on both sides. A rectangular groove for sliding the lifting rod 6 is provided at the center of the side of the fixed plate 4. The lifting rod 6 is slidably connected to the fixed plate 4, which can change the position of the lifting rod 6 and thus change the distance between the clamping plate 5 and the fixed plate 4, so as to suit the bed board or bed board frame that does not require thickness. The clamping plate 5 and the fixed plate 4 are in surface contact with the bed board, with a large contact area. Under the action of frictional resistance, the clamping plate 5 and the fixed plate 4 are stably clamped.
[0030] In this embodiment, the fixing plate 4 has an "L" shaped structure, and the end of the clamping plate 5 away from the lifting rod 6 is a right angle side. The clamping plate 5 can rotate with the position of the lifting rod 6, which can make the clamping plate 5 flip. One side of the clamping plate 5 can hook onto the bed board frame, so that the clamping plate 5 and the fixing plate 4 are clamped stably.
[0031] In this embodiment, a hook 31 with one end bent into an arc shape is fixedly connected to the outer surface of the rotating ring 3. The hook 31 can be suspended at a certain height so that the irrigation fluid collector 11 is suspended in the air, avoiding the irrigation fluid collector 11 from being easily touched when placed on the ground.
[0032] In summary: one end of the lavage fluid collection tube has a reinforced design to increase connection stability; the spiral connection between the fixing cap 12 and the lavage fluid collector 11 is a rigid connection to prevent leakage; the lifting rod 6 is slidably connected to the fixing plate 4, which can change the distance between the clamping plate 5 and the fixing plate 4 to accommodate bed boards or bed board frames of different thicknesses; the clamping plate 5 and the fixing plate 4 can clamp the bed board or bed board frame on the side of the bed to fix the fixing cap 12 and the lavage fluid collector 11, preventing the fixing cap 12 and the lavage fluid collector 11 from moving, which would cause the end of the lavage fluid collection and delivery tube 16 to be in a shaky state and thus leak. The lavage fluid collection and delivery tube 16 is made of transparent medical plastic material, which allows for visualization of the lavage fluid color during delivery; the data interface 22 connects to other medical devices to process the electrical signals generated by the light source camera 23, achieving the effect of visualizing the alveolar lavage fluid.
