Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a chest drainage tube that is easy to clear. Background Technology

[0002] A chest drainage tube is a medical device used to drain pleural effusion, pneumothorax, hemothorax, or pus. Its main purpose is to restore negative pressure in the pleural cavity and promote lung re-expansion. It is commonly used in clinical settings such as pneumothorax, pleural effusion, chest trauma, and lung surgery. The main body of the catheter is mostly made of medical-grade silicone or polyurethane, which has the characteristics of good flexibility and high tissue compatibility, and can reduce irritation to the inner wall of the pleural cavity. Clinically, water-seal bottles or chest drainage bags are commonly used, and some are combined with negative pressure suction devices.

[0003] Select the appropriate catheter type (16-24Fr for adults, 8-12Fr for children) based on the clinical scenario (pneumothorax / effusion / postoperative). Ensure that the medical silicone or polyurethane catheter is undamaged and that the drainage device (water-seal bottle or negative pressure drainage bag) is sterile. The effusion in patients with pleural effusion contains a large amount of fibrin, inflammatory cells, and necrotic tissue fragments (such as purulent sediment in patients with empyema). Postoperative drainage in patients with chest surgery contains blood clots and tissue debris. These substances gradually deposit on the inner wall of the catheter or at the side holes during the drainage process, causing blockage inside the chest drainage tube.

[0004] In existing technologies, when patients discover that the drainage tube is blocked, they usually call medical staff for treatment. If medical staff do not arrive at the patient's location in time to clear the blockage, treatment is easily delayed. Mild blockage can develop into complete blockage if delayed. What could have been solved with simple clearing may now require flushing, guidewire clearing, or even re-insertion of the tube, which not only increases the number of invasive procedures but also increases the risk of chest infection and lung tissue damage. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a chest drainage tube that is easy to clear, so as to solve the technical problems in the background art mentioned above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a chest drainage tube that is easy to clear, comprising a drainage tube body, an inner membrane, and a drainage box, wherein the inner membrane is installed on the inner wall of the drainage tube body, and a drainage box is installed at one end of the drainage tube body; One end of the drainage tube body is equipped with an air inlet pipe, and one end of the air inlet pipe is movably connected to the inner wall of the inner membrane. One end of the air inlet pipe is equipped with a first one-way valve. The other end of the air inlet pipe is equipped with an inflation ball. The other end of the drainage tube body is equipped with an air outlet pipe, and one end of the air outlet pipe is movably connected to the inner wall of the inner membrane. The other end of the air outlet pipe is equipped with an air outlet seat. The air outlet end of the air outlet seat is equipped with a second one-way valve. The inner membrane is made of rubber.

[0007] By adopting the above technical solution, the problem of timely unblocking of the drainage tube is solved. The patient repeatedly squeezes the inflatable ball, which allows airflow to enter the inner wall and the area between the inner walls of the drainage tube through the air inlet tube. This inflates the inner lining, causing it to expand from top to bottom. This pushes the accumulated fluid in the blocked area inside the drainage tube downwards, and the blood clots solidified on the outer wall of the inner lining are broken off due to the expansion of the inner lining. The detached blood clots flow downwards with the accumulated fluid into the drainage box. The gas enters the air outlet tube and is then discharged through the air outlet seat. This improves the convenience of unblocking the drainage tube after it becomes blocked, allowing the patient to unblock it themselves in a timely manner and avoiding adverse consequences caused by delayed treatment.

[0008] The present invention is further configured such that a movable seat is movably installed on the outer wall of the main body of the drainage tube, and the movable seat has a "U" shaped cross section. A movable plate is movably installed at one end of the movable seat, the outer wall of the movable plate is provided with a rubber pad layer, and a groove is provided at one end of the movable seat to be movably connected to the outer wall of the movable plate.

[0009] Preferably, one end of the movable plate is engaged inside the groove, and the patient can move the movable plate by pressing one end, so that the movable plate can be rotated with the other end as the center.

[0010] The present invention is further configured such that the upper end of the movable seat is symmetrically provided with sliding grooves, and the inner walls of the two sets of sliding grooves are movably installed with limiting plates, and the cross-section of the two sets of limiting plates is "L" shaped. The bottom end of the two sets of limiting plates is provided with a first mounting plate, and the two ends of the two sets of first mounting plates are respectively provided with a first toothed plate and a second toothed plate.

[0011] Preferably, the two sets of limiting plates are displaced inside the two sets of sliding grooves, thereby driving the two sets of first mounting plates to move, and in turn driving the two sets of first toothed plates and the two sets of second toothed plates to move.

[0012] The invention is further configured such that a first transmission shaft is symmetrically and movably mounted on the inner wall of the movable seat, and a first transmission gear is mounted at both ends of the two sets of first transmission shafts, wherein the two sets of first transmission gears are respectively meshed with two sets of first toothed plates. A second mounting plate is symmetrically and movably mounted inside the movable seat, and a first limiting toothed plate and a second limiting toothed plate are respectively mounted at both ends of the two sets of second mounting plates, wherein the two sets of first limiting toothed plates are respectively meshed with the remaining two sets of first transmission gears.

[0013] Preferably, the two sets of first toothed plates are displaced, and the two sets of first toothed plates are respectively engaged with the two sets of first transmission gears. Therefore, the two sets of first transmission gears rotate, thereby driving the two sets of first transmission shafts to rotate, and then driving the remaining two sets of first transmission gears to rotate. The remaining two sets of first transmission gears are respectively engaged with the two sets of first limiting toothed plates. Therefore, the two sets of first limiting toothed plates are displaced, thereby driving the two sets of second mounting plates to move.

[0014] The present invention is further configured such that the inner wall of the movable seat is symmetrically provided with mounting grooves, and two sets of limiting blocks are movably mounted at one end of each of the two sets of mounting grooves. Limiting shafts are movably mounted between the multiple sets of limiting blocks, and both sets of limiting shafts are damping rotating shafts. Limiting gears are mounted at the center ends of both sets of limiting shafts, and the two sets of limiting gears are respectively meshed with two sets of second limiting gear plates.

[0015] Preferably, the two sets of second mounting plates are displaced, which in turn causes the two sets of second limiting tooth plates to be displaced. The two sets of second limiting tooth plates are respectively engaged with the two sets of limiting gears, so the two sets of limiting gears rotate, thereby causing the two sets of limiting shafts to rotate.

[0016] The present invention is further configured such that extrusion blocks are installed on the outer walls of both sets of limiting shafts, and the ends of both sets of extrusion blocks are arc-shaped.

[0017] Preferably, the two sets of limiting shafts rotate, and the two sets of limiting shafts drive the two sets of extrusion blocks to rotate around the two sets of limiting shafts as the center.

[0018] The present invention is further configured such that a second transmission shaft is symmetrically and movably installed on the inner wall of the movable seat, a second transmission bevel gear is installed on the upper end of each of the two sets of second transmission shafts, and the two sets of second transmission bevel gears are respectively meshed with two sets of second tooth plates, and a transmission bevel gear is installed on the bottom end of each of the two sets of second transmission shafts.

[0019] Preferably, the two sets of first mounting plates continuously move, causing the two sets of second toothed plates to mesh with the two sets of second transmission gears respectively. As a result, the two sets of second transmission gears rotate, thereby driving the two sets of second transmission shafts to rotate, which in turn drives the two sets of transmission bevel gears to rotate.

[0020] The present invention is further configured such that movable shafts are symmetrically and movably installed inside the movable seat, and movable bevel gears are installed at one end of each of the two sets of movable shafts, and the two sets of movable bevel gears are respectively meshed with two sets of transmission bevel gears.

[0021] Preferably, the two sets of transmission bevel gears rotate, and the two sets of transmission bevel gears are respectively meshed with the two sets of movable bevel gears. Therefore, the two sets of movable bevel gears rotate, thereby driving the two sets of movable shafts to rotate.

[0022] The present invention is further configured such that multiple sets of connecting shafts are movably installed inside the movable seat, and the outer walls of the multiple sets of connecting shafts are respectively threaded to the inner walls of multiple sets of limiting blocks, and the multiple sets of connecting shafts are respectively connected to two sets of movable shafts by a toothed synchronous belt.

[0023] Preferably, the two sets of movable shafts rotate, and the two sets of movable shafts are connected to multiple sets of connecting shafts through toothed synchronous belts. Thus, the multiple sets of connecting shafts are connected, and the outer walls of the multiple sets of connecting shafts are threadedly connected to the inner walls of multiple sets of limit blocks, thus the multiple sets of limit blocks are displaced.

[0024] In summary, the present invention has the following main beneficial effects: This invention, by incorporating a drainage tube body, an inner membrane, an inflatable ball, and an air outlet seat, solves the problem of timely unblocking of the drainage tube. Patients repeatedly squeeze the inflatable ball, causing airflow to enter the inner wall and surrounding area of ​​the drainage tube body through the inlet tube. This airflow inflates the inner membrane from top to bottom, pushing the accumulated fluid in the blocked area downwards. Blood clots solidified on the outer wall of the inner membrane are broken down by the expansion and detach. The detached blood clots flow downwards with the accumulated fluid into the drainage box. Gas enters the outlet tube and is then discharged through the air outlet seat. This significantly improves the ease of unblocking the drainage tube, allowing patients to clear the blockage themselves promptly and avoiding adverse consequences caused by delayed treatment.

[0025] This invention features a movable seat and squeezing blocks. Before the patient performs any unblocking work on the drainage tube, the patient pushes out two sets of squeezing blocks from the movable seat to seal the upper part of the drainage tube, preventing backflow of fluid during the unblocking process. After the unblocking is completed, the patient pulls the movable seat along the outer wall of the drainage tube, causing the two sets of squeezing blocks to move along the outer wall of the drainage tube. During the movement of the two sets of squeezing blocks, the residual viscous liquid on the outer wall of the intima is further cleaned, pushing the viscous liquid downward with the squeezing blocks and improving the efficiency of gas discharge from the intima.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of the present invention will now be described.

[0030] An easy-to-drain chest drainage tube, such as Figure 1 - Figure 10 As shown, it includes a drainage tube body 1, an inner membrane 2, and a drainage box 9. The inner membrane 2 is installed on the inner wall of the drainage tube body 1, and the drainage box 9 is installed at one end of the drainage tube body 1. One end of the drainage tube body 1 is equipped with an air inlet tube 4, which is movably connected to the inner wall of the endothelial membrane 2. One end of the air inlet tube 4 is equipped with a first one-way valve 5, and the other end of the air inlet tube 4 is equipped with an inflation ball 3. The other end of the drainage tube body 1 is equipped with an air outlet tube 7, which is movably connected to the inner wall of the endothelial membrane 2. The other end of the air outlet tube 7 is equipped with an air outlet seat 6, and the air outlet end of the air outlet seat 6 is equipped with a second one-way valve 8. The endothelial membrane 2 is made of rubber. When the patient repeatedly squeezes the inflation ball 3, the airflow enters the area between the inner wall of the drainage tube body 1 and the endothelial membrane 2 through the air inlet tube 4, and blows the endothelial membrane 2 to expand. The endothelial membrane 2 expands from top to bottom, thereby pushing the accumulated fluid in the blocked area inside the drainage tube body 3 downward. The blood clots solidified on the outer wall of the endothelial membrane 2 are broken due to the expansion of the endothelial membrane 2 and fall off. The detached blood clots flow downward with the accumulated fluid and eventually flow into the drainage box 9. The gas enters the air outlet tube 7 and is then discharged through the air outlet seat 6.

[0031] Please see Figure 6 The main body 1 of the drainage tube is movably mounted on the outer wall of the movable seat 10, and the movable seat 10 is U-shaped in cross section. A movable plate 13 is movably mounted on one end of the movable seat 10. The outer wall of the movable plate 13 is provided with a rubber pad layer, and a groove is opened at one end of the movable seat 10 to movably connect with the outer wall of the movable plate 13. One end of the movable plate 13 is engaged in the groove. The patient can move one end of the movable plate 13 to make it rotate, so that the movable plate 13 can be rotated with the other end as the center.

[0032] Please see Figure 6 - Figure 9 The upper end of the movable seat 10 is symmetrically provided with sliding grooves 11. Limiting plates 14 are movably installed on the inner walls of the two sets of sliding grooves 11, and the cross-section of the two sets of limiting plates 14 is "L" shaped. The bottom end of the two sets of limiting plates 14 is provided with a first mounting plate 15. The two ends of the two sets of first mounting plates 15 are respectively provided with a first toothed plate 16 and a second toothed plate 17. The two sets of limiting plates 14 are displaced inside the two sets of sliding grooves 11, thereby driving the two sets of first mounting plates 15 to move, and then driving the two sets of first toothed plates 16 and the two sets of second toothed plates 17 to move.

[0033] Please see Figure 7 - Figure 9The movable seat 10 has two sets of first drive shafts 18 symmetrically and movably mounted on its inner wall. Each end of the two sets of first drive shafts 18 is equipped with a first drive gear 19, and each of the two sets of first drive gears 19 meshes with a first gear plate 16. The movable seat 10 also has two sets of second mounting plates 20 symmetrically and movably mounted inside. Each end of the two sets of second mounting plates 20 is equipped with a first limiting gear plate 21 and a second limiting gear plate 22, and each of the two sets of first limiting gear plates 21 meshes with the remaining two sets of first drive gears 19. The two sets of first gear plates 16 move, meshing with the two sets of first drive gears 19, causing the two sets of first drive gears 19 to rotate. This rotation drives the two sets of first drive shafts 18 to rotate, which in turn drives the remaining two sets of first drive gears 19 to rotate. The remaining two sets of first drive gears 19 mesh with the two sets of first limiting gear plates 21, causing the two sets of first limiting gear plates 21 to move, which in turn moves the two sets of second mounting plates 20.

[0034] Please see Figure 6 - Figure 10 The inner wall of the movable seat 10 is symmetrically provided with mounting grooves 12. Two sets of limiting blocks 24 are movably mounted at one end of each set of mounting grooves 12. Limiting shafts 23 are movably mounted between the multiple sets of limiting blocks 24. Both sets of limiting shafts 23 are damping rotating shafts. Limiting gears 25 are mounted at the center end of each set of limiting shafts 23. The two sets of limiting gears 25 are respectively meshed with two sets of second limiting gear plates 22. When the two sets of second mounting plates 20 are displaced, they drive the two sets of second limiting gear plates 22 to be displaced. The two sets of second limiting gear plates 22 are respectively meshed with the two sets of limiting gears 25. Therefore, when the two sets of limiting gears 25 are rotated, they drive the two sets of limiting shafts 23 to rotate.

[0035] Please see Figure 6 - Figure 10 Both sets of limiting shafts 23 have extrusion blocks 26 installed on their outer walls. The ends of both sets of extrusion blocks 26 are arc-shaped. When the two sets of limiting shafts 23 rotate, they drive the two sets of extrusion blocks 26 to rotate around the two sets of limiting shafts 23 as the center.

[0036] Please see Figure 7 - Figure 9 The inner wall of the movable seat 10 is symmetrically and movably mounted with second drive shafts 28. The upper ends of the two sets of second drive shafts 28 are each equipped with second drive bevel gears 29, and the two sets of second drive bevel gears 29 are respectively meshed with the two sets of second toothed plates 17. The bottom ends of the two sets of second drive shafts 28 are each equipped with drive bevel gears 30. The two sets of first mounting plates 15 continuously move, so that the two sets of second toothed plates 17 are respectively meshed with the two sets of second drive gears 29. Therefore, the two sets of second drive gears 29 rotate, thereby driving the two sets of second drive shafts 28 to rotate, and in turn driving the two sets of drive bevel gears 30 to rotate.

[0037] Please see Figure 7 - Figure 9 The movable base 10 has two movable shafts 31 symmetrically mounted inside. Each of the two movable shafts 31 has a movable bevel gear 32 mounted at one end. The two movable bevel gears 32 are respectively engaged with two sets of transmission bevel gears 30. When the two sets of transmission bevel gears 30 rotate, they are respectively engaged with the two sets of movable bevel gears 32. Therefore, when the two sets of movable bevel gears 32 rotate, they drive the two sets of movable shafts 31 to rotate.

[0038] Please see Figure 7 - Figure 10 Multiple sets of connecting shafts 27 are movably installed inside the movable seat 10, and the outer walls of the multiple sets of connecting shafts 27 are threadedly connected to the inner walls of multiple sets of limiting blocks 24. The multiple sets of connecting shafts 27 are connected to two sets of movable shafts 31 by toothed synchronous belts. The two sets of movable shafts 31 rotate, and the two sets of movable shafts 31 are connected to the multiple sets of connecting shafts 27 by toothed synchronous belts. Therefore, the multiple sets of connecting shafts 27 are connected. The outer walls of the multiple sets of connecting shafts 27 are threadedly connected to the inner walls of multiple sets of limiting blocks 24, so the multiple sets of limiting blocks 24 are displaced.

[0039] The working principle of this invention is as follows: When the patient discovers that the drainage tube body 1 is blocked, the patient pushes the two sets of limiting plates 14 to move inside the two sets of sliding grooves 11, thereby driving the two sets of first mounting plates 15 to move, and then driving the two sets of first toothed plates 16 and the two sets of second toothed plates 17 to move. The two sets of first toothed plates 16 are respectively meshed with the two sets of first transmission gears 19, so the two sets of first transmission gears 19 rotate, thereby driving the two sets of first transmission shafts 18 to rotate, and then driving the remaining two sets of first transmission gears 19 to rotate. The remaining two sets of first transmission gears 19 are respectively meshed with the two sets of first limiting toothed plates 21, so the two sets of first limiting toothed plates 21 move, thereby driving the two sets of second mounting plates 20 to move, and then driving the two sets of second limiting toothed plates 22 to move. When the two sets of second limiting tooth plates 22 are displaced, the two sets of second limiting tooth plates 22 are respectively engaged with the two sets of limiting gears 25. Therefore, the two sets of limiting gears 25 rotate, thereby driving the two sets of limiting shafts 23 to rotate. The two sets of limiting shafts 23 respectively drive the two sets of extrusion blocks 26 to rotate around the two sets of limiting shafts 23 as the center, so that the two sets of extrusion blocks 26 are both facing the drainage tube body 1. When the two sets of extrusion blocks 26 rotate, the two sets of limiting plates 14 continue to move, the two sets of first toothed plates 16 separate from the two sets of first transmission gears 19 respectively, and the two sets of first mounting plates 15 continue to move, so that the two sets of second toothed plates 17 respectively mesh with the two sets of second transmission gears 29. Therefore, the two sets of second transmission gears 29 rotate, thereby driving the two sets of second transmission shafts 28 to rotate, which in turn drives the two sets of transmission bevel gears 30 to rotate. The two sets of transmission bevel gears 30 respectively mesh with the two sets of movable bevel gears 32. Therefore, the two sets of movable bevel gears 32 rotate, thereby driving the two sets of movable shafts 31 to rotate. When the two sets of movable shafts 31 rotate, the two sets of movable shafts 31 are connected to multiple sets of connecting shafts 27 through toothed synchronous belts. Therefore, the multiple sets of connecting shafts 27 are connected, and the outer walls of the multiple sets of connecting shafts 27 are threadedly connected to the inner walls of multiple sets of limiting blocks 24. Therefore, the multiple sets of limiting blocks 24 are displaced, thereby driving the two sets of limiting shafts 23 to move, and then driving the two sets of squeezing blocks 26 to move. Both sets of squeezing blocks 26 move towards the drainage tube body 1. The two sets of squeezing blocks 26 cooperate to temporarily close one end of the drainage tube body 1 to prevent the accumulated liquid from flowing back upward when the drainage tube body 1 is being cleared. After the upper part of the drainage tube body 1 is closed, the patient repeatedly squeezes the inflation ball 3. Airflow is continuously injected into the sealed area between the inner wall of the drainage tube body 1 and the intima 2 through the air inlet tube 4. This drives the intima 2 to gradually expand from top to bottom along the drainage tube body 1. During the expansion of the intima 2, its inner wall expands synchronously towards the central axis of the drainage tube body 1, forming a radial compressive force. This forms a closed compression space with the inner wall of the drainage tube body 1. At the same time, the expansion movement of the intima 2 from top to bottom generates an axial thrust, which is exerted through the inner wall and the accumulated fluid. The adhesive conduction generates a continuous downward pushing force on the effusion, and the blood clots solidified on the outer wall of the endometrium 2 are broken due to the expansion of the endometrium 2, thus falling off. The detached blood clots flow down along the internal channel of the drainage tube body 1 with the effusion, and finally flow into the drainage box 9. The gas enters the vent tube 7 and then is discharged through the vent seat 6. The patient can accelerate the gas flow by repeatedly squeezing the vent seat 6, further enhancing the expansion efficiency and squeezing force of the endometrium 2, and significantly improving the unblocking effect rate inside the drainage tube body 1. Once the drainage tube body 1 is cleared, the patient can move the two sets of limiting plates 14 to reset the two sets of squeezing blocks 26, thus releasing the blockage at the upper end of the drainage tube body 1. Alternatively, the patient can flip the movable plate 13 to release the obstruction of the inlet pipe 4 to the movable seat 10. Then, the patient can pull the movable seat 10 to move along the outer wall of the drainage tube body 1, thereby moving the two sets of squeezing blocks 26 on the outer wall of the drainage tube body 1. During the movement of the two sets of squeezing blocks 26, the viscous liquid remaining on the outer wall of the inner membrane 2 is further cleaned, and the viscous liquid is pushed downward with the squeezing blocks 26, thereby improving the efficiency of gas discharge from the inner membrane 2.
