Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to an anti-blockage drainage device for thoracic surgeons as an adjunct therapy. Background Technology

[0002] Thoracic surgery is a medical specialty that studies the organs within the thoracic cavity, mainly referring to the diagnosis and treatment of diseases of the esophagus, lungs, and mediastinum. Drainage devices are a commonly used treatment method in thoracic surgery, in which one end of a drainage tube is inserted into the thoracic cavity to drain gas or collect fluid from the thoracic cavity.

[0003] Existing technology discloses some invention patents for thoracic surgical drainage devices. Chinese patent application number 201710838270.3 discloses a thoracic surgical anti-blockage drainage device, which belongs to the field of medical device technology. It includes a sealed container, a first anti-blockage device, a second anti-blockage device, a fixing device, and a drainage head. The first anti-blockage device is snapped onto the side of the fixing device. The sealed container, the first anti-blockage device, the second anti-blockage device, the fixing device, and the drainage head are connected by a flexible tube, and the flexible tube is connected to the top left side of the sealed container.

[0004] When using a drainage device to drain fluid from a patient's pleural cavity, the drained fluid is usually accompanied by blood clots or coagulated fibrin. Because the fluid drained from the body has a certain viscosity, filters or other filtration mechanisms are typically used to separate the fluid from impurities to prevent blockages in the drainage tube and impaired flow. However, filtration mechanisms can generally only intercept larger blood clots and coagulated fibrin, while some smaller flocculent particles still flow with the drainage tube. Due to the viscosity of the fluid and its slow flow rate, some flocculent particles accumulate and adhere to the inner wall of the drainage tube during flow. If not cleaned in time, this not only affects the flow rate of the fluid, but if a large amount of flocculent particles accumulates, it can also lead to blockage of the drainage tube. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This invention, through the setting of a conveying and crushing mechanism, first crushes waste such as blood clots mixed in the liquid. After crushing the waste such as blood clots, the conveying and crushing mechanism also conveys the crushed waste such as blood clots to the drainage tube. By decomposing the large volume of impurities such as blood clots into smaller volumes, it is easier to convey the waste such as blood clots to the drainage tube. Furthermore, the flow impact force generated when the conveying and crushing mechanism conveys the impurities such as blood clots also helps the waste such as blood clots to enter the collection bottle better through the drainage tube, which helps to prevent the crushed waste such as blood clots from adhering to the inner wall of the drainage tube.

[0020] 2. The present invention, through the setting of the scraping and cleaning mechanism, moves along the inner wall of the drainage tube, which is conducive to scraping and cleaning the flocculent material adhering to the inner wall of the drainage tube, and helps to prevent the flocculent material from accumulating on the inner wall of the drainage tube and causing blockage of the drainage tube.

[0021] 3. The present invention uses a magnetic ring, which causes the scraping ring to adhere to the inner ring of the magnetic ring. As the magnetic ring moves, it also helps to move the scraping ring synchronously. The magnetic ring also helps the scraping ring to adhere tightly to the inner wall of the drainage tube, so that the scraping ring can better scrape away impurities on the inner wall of the drainage tube.

[0039] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0040] like Figures 1 to 16 The illustrated auxiliary treatment thoracic surgeon's anti-blockage drainage device includes a sterilization box 1. Two sliding plates 2 are symmetrically fixed on one side wall of the sterilization box 1, with a gap between the two sliding plates 2. An effusion bottle 3 is fixed inside the sterilization box 1. A drainage tube 4 is fixedly connected to the outer wall of the effusion bottle 3. The end of the drainage tube 4 facing away from the effusion bottle 3 passes through the sterilization box 1 and is fixedly connected to a delivery box 5. The delivery box 5 is located between the two sliding plates 2. A drainage head 6 is fixedly connected to the side wall of the delivery box 5 facing away from the sterilization box 1. A negative pressure mechanism is provided on the side wall of the sterilization box 1 facing away from the drainage tube 4. The negative pressure mechanism is used to extract the air in the effusion bottle 3 to create a negative pressure inside.

[0041] The delivery box 5 is equipped with a delivery and crushing mechanism. After the fluid in the patient's pleural cavity enters the delivery box 5 through the drainage head 6, the delivery and crushing mechanism is used to crush the blood clots or coagulated cellulose in the delivery box 5 and then deliver them to the drainage tube 4.

[0042] The top of the disinfection box 1 is equipped with a scraping and cleaning mechanism, which is used to scrape and clean the flocculent material on the inner wall of the drainage tube 4. During operation, when using the drainage device to drain fluid from the patient's pleural cavity, the outflowing fluid is usually accompanied by blood clots or coagulated fibrin. Because the fluid discharged from the human body has a certain viscosity, in order to avoid blockage in the drainage tube 4 and affect the flow, a filter screen 18 or other filtering mechanism is usually used to separate the fluid from impurities. However, the filtering mechanism can generally only intercept larger blood clots and coagulated fibrin, etc., and some smaller flocculent material will still flow with the drainage tube 4. Because the liquid is viscous, its slow flow rate can cause some flocculent material to accumulate and adhere to the inner wall of the drainage tube 4 during the flow process. If it is not cleaned in time, it will not only affect the flow rate of the liquid, but if the flocculent material accumulates too much, it will also cause the drainage tube 4 to become blocked. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: The operator first inserts the drainage head 6 into the patient's chest cavity, and then the operator turns on the negative pressure mechanism. At this time, the negative pressure mechanism draws out the air inside the effusion bottle 3, thereby creating a negative pressure inside the effusion bottle 3, which is conducive to the flow of liquid from the patient's chest cavity. The liquid first enters the interior of the delivery box 5 through the drainage head 6. At this time, the delivery box breaks down. The crushing mechanism first breaks down blood clots and other waste mixed in the liquid. After the crushing mechanism breaks down the blood clots and other waste, it also transports the broken-down blood clots and other waste to the drainage pipe 4. By breaking down larger blood clots and other impurities into smaller volumes, it facilitates the transport of these wastes to the drainage pipe 4. The flow impact force generated during the transport of blood clots and other impurities by the crushing mechanism also helps the blood clots and other wastes to pass more easily through the drainage pipe 4 into the collection bottle 3. This helps prevent the broken-down blood clots and other wastes from adhering to the inner wall of the drainage pipe 4. After the liquid flows inside the drainage pipe 4 for a certain period of time, some smaller flocculent materials... Due to its stickiness, the fluid may adhere to the inner wall of the drainage tube 4. At this time, the scraping and cleaning mechanism is activated. As the scraping and cleaning mechanism moves along the inner wall of the drainage tube 4, it smooths out the wrinkles in the drainage tube 4, keeping the drainage tube 4 full. This helps prevent the drainage tube 4 from affecting the flow of fluid when it is bent. The scraping and cleaning mechanism also helps to scrape and clean the flocculent material adhering to the inner wall of the drainage tube 4, preventing the flocculent material from accumulating on the inner wall of the drainage tube 4 and causing blockage, thus avoiding harm to the patient. When the fluid is drained into the collection bottle 3, the disinfection box 1 will disinfect simultaneously.

[0043] In one embodiment of the present invention, the negative pressure mechanism includes a medical negative pressure pump 7, which is fixed to the side wall of the disinfection box 1. The air inlet of the medical negative pressure pump 7 is fixedly connected to an air suction pipe 8. One end of the air suction pipe 8 facing away from the medical negative pressure pump 7 passes through the side wall of the disinfection box 1 and is fixedly connected to the effusion bottle 3. During operation, the operator turns on the medical negative pressure pump 7, and the medical negative pressure pump 7 will draw out the air from the inner wall of the effusion bottle 3 through the air suction pipe 8, thereby creating a negative pressure space inside the effusion bottle 3, which is conducive to the drainage head 6 draining the fluid in the patient's pleural cavity.

[0044] In one embodiment of the present invention, the conveying and crushing mechanism includes a first motor 9 and a crushing mechanism. The first motor 9 is fixed to the top of one of the sliding plates 2. The output shaft of the first motor 9 passes through the conveying box 5 and is fixed to a rotating drum 10. An elastic circular block 11 is fixed at the center of the rotating drum 10. Multiple actuating blocks 12 are fixed in a circular array around the outer periphery of the elastic circular block 11. A roller 13 is fixed to the end of all actuating blocks 12 facing away from the elastic circular block 11 through a connecting plate. The end of all actuating blocks 12 facing away from the elastic circular block 11 is slidably connected to the rotating drum 10. The crushing mechanism is installed between the rotating drum 10 and the connection end of the drain head 6. When the roller 13 rotates counterclockwise, the roller 13 is used to drive the crushing mechanism to crush blood clots or coagulated cellulose entering the conveying box 5. During operation, in liquids and those mixed with... When impurities such as blood clots enter the interior of the conveying box 5 through the drainage head 6, the first motor 9 is started. The first motor 9 drives the rotating drum 10 to rotate, and the rotating drum 10 drives the elastic block 11 to rotate. The elastic block 11 is a type of elastic material. The rotation of the elastic block 11 also drives the actuating block 12 to rotate. The actuating block 12 drives the roller 13 to rotate. During the rotation of the roller 13, it contacts the drive mechanism and drives the crushing mechanism to move downward. The crushing mechanism breaks down the blood clots and other impurities into smaller volumes, which is beneficial for subsequent conveying and also helps the blood clots and other impurities to enter the drainage pipe 4 better, preventing blockage of the drainage pipe 4. Furthermore, the force generated by the actuating block 12 during rotation helps the blood clots and other impurities to pass through the drainage pipe 4 better, which helps prevent accumulation in the drainage pipe 4.

[0045] In one embodiment of the present invention, the crushing mechanism includes a baffle plate 14, a first crushing plate 15, and a second crushing plate 16. The top of the baffle plate 14 is fixedly connected to the inner top surface of the conveying box 5. A sliding groove is vertically opened through the middle of the baffle plate 14. Filter screens 18 are symmetrically fixed at the bottom of the baffle plate 14, and the bottom of the filter screens 18 is fixedly connected to the inner bottom surface of the conveying box 5. A tension spring 19 is fixed to the top of the first crushing plate 15, and the top of the tension spring 19 is fixed to the inner top surface of the conveying box 5. Multiple first crushing blades 20 are fixed in a linear array at the bottom of the first crushing plate 15. The second crushing plate 16 is fixed to the inner bottom surface of the conveying box 5, and the top of the second crushing plate 16 is in a linear array. Multiple second crushing blades 21 are fixed, and all the first crushing blades 20 and all the second crushing blades 21 are staggered. The first crushing plate 15 and the second crushing plate 16 are both located between the guide head 6 and the baffle plate 14. A mating block 23 is fixed on the side wall of the first crushing plate 15 facing away from the guide head 6. The end of the mating block 23 facing away from the guide head 6 extends out after passing through the sliding groove. The mating block 23 cooperates with the actuating block 12. During operation, when the drum 13 rotates and contacts the mating block 23, it causes the mating block 23 to move downward. The mating block 23 causes the first crushing plate 15 to move downward. The first crushing plate 15 will cause the tension spring 19 to deform, and the first crushing plate 15 will cause the first crushing blade 20 to move downward. When the first crusher 20 moves to its lowest position, the staggered arrangement of the first crusher 20 and the second crusher 21 facilitates the crushing and decomposition of blood clots and other impurities by the first crusher 20 in conjunction with the second crusher 21. As the first crushing plate 15 moves downward, it applies downward pressure, which helps to guide the liquid and the crushed blood clots and other impurities from the top to the bottom of the conveying box 5. This allows the liquid to flow through the filter screen 18 into the actuating block 12, thus cooperating with the actuating block 12 to transport the liquid and impurities into the drainage pipe 4. This facilitates the transport of blood clots and other impurities and reduces the likelihood of clogging the drainage pipe 4. The roller 13 continues to rotate, causing the actuating block... The compression of the elastic circular block 11 causes deformation to make way, and the roller 13 can reduce friction. As the roller 13 continues to rotate, it moves away from the mating block 23. Then, the first crushing plate 15 returns to its original position under the action of the tension spring 19. Because a one-way valve is installed on the top of the first crushing plate 15 and the outlet of the one-way valve is set downward, during the return of the first crushing plate 15, the liquid above the conveying box 5 can flow along the outlet of the one-way valve to the bottom space of the conveying box 5. This is conducive to the first crushing blade 20 and the second crushing blade 21 to crush and decompose the blood clot and other impurities again. This cycle is repeated, which is conducive to continuously crushing and conveying the blood clot and other impurities entering the conveying box 5.

[0046] In one embodiment of the present invention, the scraping and cleaning mechanism includes a scraping ring 24, which is located inside the drainage tube 4 and closely adheres to the inner wall of the drainage tube 4. Tension frames 25 are fixed to both ends of the scraping ring 24. A winding device is provided between the tension frame 25 facing the elastic block 11 and the conveying box 5. A first thin rope 26 is fixed to the side of the other tension frame 25 facing away from the winding device. A driving mechanism is installed between the first thin rope 26 and the disinfection box 1. The driving mechanism drives the scraping ring 24 to scrape and clean the inner wall of the drainage tube 4 by winding the first thin rope 26. During operation, the operator activates the driving mechanism, which drives the first thin rope 26 to wind up. When the first thin rope 26 winds up, it moves the tension frame 25. Simultaneously, the winding device unwinds, and the tension frame 25 moves. The scraping ring 24 will move, and during its movement, it will scrape off the flocculent material adhering to the inner wall of the drainage tube 4. The movement will also generate guiding force, which will help the flocculent material move towards the collection bottle 3 along with the scraping ring 24 after being scraped off. This will help prevent the accumulation of flocculent material and also help the drainage tube 4 to flow smoothly. At the same time, the scraping ring 24 will smooth out the wrinkles inside the drainage tube 4 during its movement, which will help prevent the drainage tube 4 from bending and affecting the drainage effect, and reduce the possibility of blockage. After one round of cleaning, the scraping ring 24 can be returned to its original position by the winding device. During the return process, the inner wall of the drainage tube 4 will be cleaned again, which will help keep the inner wall of the drainage tube 4 clean.

[0047] In one embodiment of the present invention, the driving mechanism includes a second motor 27 and a U-shaped block 28. Both the second motor 27 and the U-shaped block 28 are fixed to the top of the disinfection box 1. Multiple first take-up rollers 29 are linearly arrayed and rotatably mounted between the two side walls of the U-shaped block 28. The output shaft of the second motor 27 passes through the U-shaped block 28 and is coaxially and fixedly connected to one of the first take-up rollers 29. The outer wall of the first take-up roller 29 is fixedly connected to a first thin rope 26, which wraps around the remaining first take-up rollers 29 in an S-shape. During operation, the mechanism is activated. The second motor 27 drives one of the first take-up rollers 29 to rotate. During the rotation of the first take-up roller 29, the first take-up roller 29 winds up the first thin rope 26. The other first take-up rollers 29 tighten and support the first thin rope 26 as it passes through. During the winding process, the disinfection box 1 disinfects the first thin rope 26 simultaneously, which helps to keep the first thin rope 26 clean. This, in turn, helps to drive the scraping ring 24 to clean the inner wall of the drainage tube 4, thus helping to keep the drainage tube 4 unobstructed.

[0048] In one embodiment of the present invention, the winding device includes an air extraction cylinder 30, an air extraction rod 31 slidably connected inside the air extraction cylinder 30, the top end of the air extraction rod 31 located outside the air extraction cylinder 30, an air extraction disc 32 fixed to the bottom end of the air extraction rod 31, a telescopic rod 33 fixed at the bottom center of the air extraction disc 32, a rotating roller 35 rotatably mounted at the bottom of the telescopic end of the telescopic rod 33, a driving member 34 fixed after the rotating shaft of the rotating roller 35 passes through the side wall of the air extraction cylinder 30, and a second thin rope 36 is fixed on the outer wall of the rotating roller 35. The end of the second thin rope 36 facing away from the elastic circular block 11 passes through the disinfection box 1 and is fixedly connected to the tension frame 25. During operation, when the scraping ring 24 moves towards the liquid collection bottle 3, the scraping ring 24 drives the second thin rope 36 to move through the tension frame 25, so that the rotating roller 35 will simultaneously unwind the second thin rope 36, which is beneficial. To adapt to the movement trajectory of the scraping ring 24, when the scraping ring 24 needs to return to its original position, the drive unit 34 can be manually rotated by a motor or by the operator. By starting the drive unit 34, the drive unit 34 drives the telescopic rod 33 to rotate, and the telescopic rod 33 drives the rotating roller 35 to rotate. Thus, the rotating roller 35 winds up the second thin rope 36, which is beneficial for the scraping ring 24 to clean the inner wall of the drainage tube 4 again during the return process. If the operator finds that the drainage rate is slow during the drainage process in the drainage tube 4, the operator can pull the suction rod 31. The suction rod 31 pulls the suction disc 32, and the suction disc 32 drives the telescopic rod 33 to extend and retract, which is beneficial for adapting to the movement trajectory of the suction disc 32. This reduces the air pressure inside the delivery box 5, which is beneficial for the liquid to enter the interior of the drainage tube 4 better.

[0049] In one embodiment of the present invention, a sliding block 37 is slidably connected to the top of two sliding plates 2. A circular hole 38 is provided through one side wall of the sliding block 37. A magnetic ring 40 is fixed inside the circular hole 38 by a support column. The magnetic ring 40 cooperates with the scraping ring 24 and is sleeved on the outer wall of the drainage tube 4. A transmission mechanism is provided between the top of the sliding block 37 and the U-shaped block 28. The transmission mechanism is used to drive the sliding block 37 and the scraping ring 24 to move synchronously. During operation, although the scraping ring 24 can process the particles adhering to the inner wall of the drainage tube 4 during its movement inside the drainage tube 4, if the scraping ring 24 is subjected to external pressure during its movement, it may tilt. Although the scraping ring 24 can still clean the inner wall, it will affect the scraping effect and cause the cleaning effect to not meet expectations. This embodiment of the present invention can solve the above problems. The specific implementation is as follows: the scraping ring 24 can be attracted to the magnetic ring 40, and the inner wall of the magnetic ring 40 is... The magnetic ring 40 is located on the outer ring of the scraping ring 24. The transmission mechanism moves the sliding block 37 along the outer wall of the drainage tube 4. The sliding block 37 drives the magnetic ring 40 to move synchronously with the scraping ring 24 via the support column. At this time, the magnetic ring 40 will cause the scraping ring 24 to be attracted to the inner ring of the magnetic ring 40. Thus, during the movement of the magnetic ring 40, it will also assist in driving the scraping ring 24 to move synchronously. Moreover, the setting of the magnetic ring 40 is conducive to the scraping ring 24 adhering tightly to the inner wall of the drainage tube 4, so that the scraping ring 24 can be more... The magnetic ring 40 effectively scrapes away impurities from the inner wall of the drainage tube 4. The magnetic ring 40, adsorbed by the scraping ring 24, helps maintain the verticality of the scraping ring 24 within the drainage tube 4, preventing it from tilting during movement. This facilitates the removal of flocculent material from the inner wall of the drainage tube 4, preventing blockage. Furthermore, the cooperation between the magnetic ring 40 and the scraping ring 24 helps smooth out bends in the drainage tube 4, ensuring good flow.

[0050] In one embodiment of the present invention, a cylinder 41 is fixed to the side of the sliding block 37 facing the disinfection box 1. Multiple fixed posts 42 are fixed in a circumferential array inside the cylinder 41. All fixed posts 42 have a groove 43 at their ends facing the drainage pipe 4. All grooves 43 are slidably connected to a support column 44. All support columns 44 are rotatably connected to a pulley 45 on their outer walls. All pulleys 45 abut against the drainage pipe 4. A moving rod 47 is fixedly connected to the outer wall of all support columns 44. The moving rod 47 is slidably connected to the fixed posts 42. The end of the moving rod 47 facing away from the pulley 45 extends through an adjacent fixed post 42 and is fixedly fitted with a round cover 48. A return spring 49 is fixed between the round cover 48 and the fixed post 42. The return spring 49 is sleeved on the outer wall of the moving rod 47. During operation, as the moving scraping ring 24 moves, although the magnetic ring 40 can better facilitate the scraping ring 24's drainage... The inner wall of tube 4 is scraped and cleaned. However, if the drainage tube 4 bends or wrinkles during the drainage process, the scraping ring 24 will not pass smoothly, and it will be easier for flocculent material to accumulate and block the inside of the drainage tube 4. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the sliding block 37 moves and drives the cylinder 41 to move. The cylinder 41 drives the fixed column 42 to move. The fixed column 42 drives the pulley 45 to move through the support column 44. The movement of the support column 44 drives the moving rod 47 to move. The moving rod 47 drives the round cover 48 to move. The reset spring 49 provides a certain support force to the pulley 45. During the movement, the pulley 45 will also help smooth out the bends or wrinkles of the drainage tube 4 to maintain the best flow state. This is beneficial for the drainage of liquid in the drainage tube 4 and also for the scraping ring 24 to scrape and clean the inner wall of the drainage tube 4.

[0051] In one embodiment of the present invention, the transmission mechanism includes a fixed base 46, a first gear 17, a second gear 22, and a second take-up roller 50. The second take-up roller 50 is rotatably connected inside the U-shaped block 28. The first gear 17 is fixed to the outer wall of the output shaft of the second motor 27. The fixed base 46 is fixed to the top of the sliding block 37. A pull rope 39 is fixed to the side wall of the fixed base 46. One end of the pull rope 39 facing away from the fixed base 46 is fixedly connected to the second take-up roller 50. The second gear 22 is fixed to the outer wall of the connecting rod of the second take-up roller 50. The first gear 17 and the second gear 22 mesh. During operation, the second motor 27 drives the first gear 17 to rotate, the first gear 17 drives the second gear 22 to rotate, and the second gear 22 drives the second take-up roller 50 to rotate, thereby causing the second take-up roller 50 to wind up the pull rope 39. The pull rope 39 drives the sliding block 37 to move, thereby causing the magnetic ring 40 and the scraping ring 24 to move synchronously, which is beneficial for scraping and cleaning the inner wall of the drainage tube 4.

[0052] Working principle of this invention: During the drainage of fluid from a patient's pleural cavity using a drainage device, the outflowing fluid is generally accompanied by blood clots or coagulated fibrin. Because the fluid expelled from the body has a certain viscosity, a filter screen 18 or other filtration mechanism is typically used to separate the fluid from impurities to avoid blockage in the drainage tube 4 and affecting flow. However, filtration mechanisms generally only intercept larger blood clots and coagulated fibrin, etc. Some smaller flocculent particles still flow with the drainage tube 4. Due to the viscosity of the fluid and the slow flow rate, some flocculent particles will remain in the flow. Accumulated and adhered to the inner wall of the drainage tube 4, if not cleaned in time, will not only affect the flow rate of the fluid, but if the accumulation of flocculent material is too large, it will also cause blockage of the drainage tube 4. This embodiment of the invention can solve the above problems. The specific implementation method is as follows: The operator first inserts the drainage head 6 into the patient's chest cavity, and then the operator turns on the negative pressure mechanism. At this time, the negative pressure mechanism draws out the air inside the effusion bottle 3, thereby creating a negative pressure inside the effusion bottle 3, which is conducive to the flow of fluid from the patient's chest cavity. The fluid first enters the interior of the delivery box 5 through the drainage head 6. At this time, the delivery and crushing mechanism begins to crush the blood clots and other waste mixed in the fluid. After the blood clots and other waste are crushed by the conveying and crushing mechanism, the crushed blood clots and other waste are also conveyed to the drainage pipe 4. By breaking down larger blood clots and other impurities into smaller volumes, it is easier to convey the blood clots and other waste to the drainage pipe 4. The flow impact force generated when the conveying and crushing mechanism conveys the blood clots and other impurities also helps the blood clots and other waste to pass through the drainage pipe 4 and enter the collection bottle 3 more easily. This helps to prevent the crushed blood clots and other waste from adhering to the inner wall of the drainage pipe 4. After the liquid flows inside the drainage pipe 4 for a certain period of time, some smaller flocculent materials may stick due to their viscosity. The fluid adheres to the inner wall of the drainage tube 4. At this time, the scraping and cleaning mechanism is activated. As the scraping and cleaning mechanism moves along the inner wall of the drainage tube 4, it smooths out the wrinkles of the drainage tube 4, keeping the drainage tube 4 full. This helps to prevent the drainage tube 4 from affecting the flow of fluid when it is bent. The scraping and cleaning mechanism also helps to scrape and clean the flocculent material adhering to the inner wall of the drainage tube 4, which helps to prevent the flocculent material from accumulating on the inner wall of the drainage tube 4 and causing blockage, thus avoiding harm to the patient. When the fluid is drained into the collection bottle 3, the disinfection box 1 will disinfect simultaneously.
