Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically referring to a chest drainage device. Background Technology

[0002] Thoracic drainage is a crucial treatment method for patients after thoracic surgery and for those with pleural effusion or pneumothorax. By establishing a negative pressure pathway to drain pleural effusion, air, and foreign bodies, it rapidly restores the negative pressure environment within the pleural cavity, ensuring lung re-expansion, preventing infection, and promoting patient recovery. It holds an irreplaceable position in clinical treatment. However, traditional thoracic drainage devices have significant drawbacks in clinical application: A. In particular, during the drainage process, it is very easy to be blocked by solid or semi-solid substances such as blood clots, fibrin flocs and viscous sputum in the effusion. These substances are easy to accumulate in the drainage tube lumen, filter screen and other key components, causing poor drainage or even complete blockage. This directly leads to the inability to effectively drain effusion and gas in the pleural cavity, which in turn causes complications such as delayed lung re-expansion, pleural infection and pleural adhesion. B. In order to ensure smooth drainage, medical staff frequently manually flush or change the drainage device, which not only increases the operational burden and medical costs, but also increases the risk of nosocomial infection for patients. For patients requiring long-term drainage, frequent replacement of internal drainage components is impractical, raising the barrier to entry for patients and increasing the difficulty of care for nursing staff. Summary of the Invention

[0003] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a thoracic drainage device. While ensuring drainage effectiveness, this device adopts a modular design. Through the cooperation of the pushing fan blades and the sliding pushing component, it solves the problem of traditional devices being easily blocked by blood clots and mucus. It can achieve an autonomous anti-blocking effect without manual intervention while breaking up clots. The anti-blocking filter replacement component can be quickly disassembled and assembled. The structure is simple and inexpensive, suitable for mass production. It can be directly replaced without the need for nursing staff to rinse, greatly improving the efficiency of clinical operations.

[0004] The technical solution adopted by this invention is as follows: This invention proposes a thoracic drainage device, including an anti-clogging filter replacement component, a negative pressure drainage device, a drainage connector, and a collection connector. The drainage connector is rotatably engaged with the anti-clogging filter replacement component, and the collection connector is rotatably engaged with the negative pressure drainage device. The negative pressure drainage device is connected to the anti-clogging filter replacement component. The anti-clogging filter replacement component includes a mounting locking ring and an anti-clogging filter tube. The bottom surface of the mounting locking ring is fixedly connected to the anti-clogging filter tube. The negative pressure drainage device is rotatably engaged with the mounting locking ring. The negative pressure drainage device includes a mounting plate and an electric negative pressure pump. The electric negative pressure pump is fixedly mounted on the mounting plate. A diversion tube is fixedly connected to the mounting plate. The diversion tube is engaged with the bottom of the anti-clogging filter tube. A pushing drive component is fixedly connected inside the diversion tube.

[0005] The device of this invention features a compact design with snap-fit ​​and threaded connections between its components, making it small in size and suitable for various clinical scenarios such as bedside continuous drainage and emergency transport. The anti-clogging filter replacement is an independent module that can be quickly rotated and snapped together with the negative pressure drainage device for disassembly. In clinical practice, clogged filter replacements can be directly replaced without disassembling the entire device, significantly reducing operation time and making it highly applicable.

[0006] Furthermore, the push drive provides rotational power to the anti-clogging filter chamber to achieve the anti-clogging function.

[0007] Furthermore, the locking ring assembly includes a locking outer ring and a locking inner tube. The locking outer ring is fixedly connected to the locking inner tube, and a sliding ring groove is formed between the locking outer ring and the locking inner tube. The inner wall of the locking outer ring is provided with a locking groove. The anti-clogging filter chamber includes a receiving chamber and a protective outer tube. The protective outer tube is fixedly connected to the outside of the receiving chamber. A sliding pusher and a foreign object pusher are fixedly connected inside the receiving chamber. A mesh is fixedly connected to the bottom surface of the receiving chamber.

[0008] Furthermore, the sliding pusher includes a pusher tube, a bottom support top tube, and a support column. The pusher tube is fixed to the top surface of the bottom support top tube, and the bottom support top tube is slidably sleeved on the outside of the support column. The lower end of the pusher tube has drainage holes arranged in a circumferential array. A bucket-shaped drainage plate is fixed to the bottom of the pusher tube, and the bottom support top tube is fixed to the bottom surface of the bucket-shaped drainage plate. The bottom surface of the bottom support top tube has wrapping holes, and fitting grooves are formed on both sides of the wrapping holes.

[0009] Furthermore, a support spring is provided between the top surface of the support column and the bottom surface of the bucket-shaped diversion plate. The support spring is used to support the reset sliding pusher. Side protrusions are fixed to both sides of the support column, and a support base is fixed to the bottom of the support column. The support base is fixed to the receiving cavity tube. The wrapping hole slides along the support column, and the fitting groove slides along the side protrusions. The outer wall of the support base is provided with a lower end slot.

[0010] In its initial state, the support spring supports the bottom support tube, making the top of the push tube the same height as the top of the locking ring. The push tube is completely wrapped inside the locking inner tube, the drainage hole is completely blocked, and the protruding connecting post protrudes from the bottom of the protective outer tube, facilitating the locking and installation of the anti-clogging filter replacement part.

[0011] Furthermore, the foreign object pushing component includes a rotating ring and a pushing fan blade. The pushing fan blade is fixedly connected to the outer wall of the rotating ring. The rotating ring is rotatably disposed in the lower end slot. A branch connecting post is fixedly connected to the bottom of the rotating ring. The bottom surface of the pushing fan blade slides against the top surface of the partition net.

[0012] The pusher blades in the device of this invention clean the partition screen in real time, ensuring that the drainage channel is always unobstructed and avoiding drainage interruption due to blockage.

[0013] Furthermore, the upper end of the protective outer tube is fixed to the lower part of the locking outer ring, and a locking block is fixed to the lower end of the outer wall of the protective outer tube.

[0014] Furthermore, the placement tray is provided with a placement slot, the diversion chamber is fixedly connected to the placement slot, the outer wall of the diversion chamber is fixedly connected to a mounting slot, the locking block is engaged in the mounting slot, the pushing drive component includes a drive motor and a rotating disk, the rotating disk is fixedly connected to the top of the output shaft of the drive motor, the rotating disk is provided with a locking notch, the outgoing connecting post is engaged in the locking notch, the electric negative pressure pump is connected to the diversion chamber through a pump connecting pipe, and a one-way anti-backflow valve is fixedly connected in the pump connecting pipe.

[0015] The one-way anti-backflow valve proposed in the device of this invention prevents drainage fluid from entering the electric negative pressure pump, reducing the probability of pump failure. By setting a replaceable anti-clogging filter module, the cost of clinical medical consumables is significantly reduced compared to replacing the entire drainage device.

[0016] Furthermore, as the rotating disk rotates, it drives the branch connecting column to rotate, and the rotating ring rotates along the lower end slot, causing the pusher blades to slide on the top surface of the partition net.

[0017] Furthermore, the drainage connector includes a drainage tube, an outer wrapping tube, an inner insertion tube, and a locking ring. The drainage tube is threaded to the upper end of the outer wrapping tube. A locking protrusion is fixed to the outer wall of the outer wrapping tube, and an internal locking groove is fixed to the inner wall of the outer wrapping tube. A rotating washer is rotatably engaged in the internal locking groove. The inner insertion tube is inserted and fixed inside the outer wrapping tube. A locking ring is fixed to the outside of the outer wrapping tube. The locking ring covers the top of the locking ring component. The outer wrapping tube is axially inserted into the sliding ring groove and then rotated to lock and position itself. The inner diameter of the inner insertion tube matches the outer diameter of the push tube. The rotating washer is made of medical-grade silicone to reduce the frictional resistance when the outer wrapping tube and the locking inner tube are rotated and locked, while also enhancing the sealing of the connection.

[0018] Furthermore, the engaging protrusion engages and is embedded in the engaging groove to fix the drainage connector and the engaging ring, and the engaging block engages and is embedded in the mounting slot to fix the diversion chamber and the anti-clogging filter chamber.

[0019] Furthermore, the drainage tube is connected to the patient's drainage tube, and the collection connector is connected to a medical collection bag or collection ball. The lumpy condensate is continuously pushed by the fan blades in the receiving cavity tube, which not only prevents the condensate from blocking the passage, but also concentrates the condensate. The anti-clogging filter replacement is then disassembled and replaced periodically.

[0020] The device of this invention reduces the frequency of manual flushing and pipeline replacement by periodically replacing the anti-clogging filter replacement component, thereby reducing the workload of medical staff. At the same time, the modular replacement design reduces the number of times the device comes into contact with the external environment, thus reducing the probability of patients with chest cavity infection.

[0021] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The device of the present invention adopts a compact design with snap-fit ​​and threaded connection between the components, and is small in size. It can be adapted to various clinical scenarios such as bedside continuous drainage and emergency transport. The anti-clogging filter replacement is an independent module that can be quickly rotated and snapped with the negative pressure drainage device for disassembly. In clinical practice, the clogged filter replacement can be directly replaced without disassembling the entire device, which greatly shortens the operation time and has strong applicability.

[0022] (2) In the initial state, the support spring supports the bottom support tube, so that the top of the push tube is at the same height as the top of the locking ring. The push tube is completely wrapped in the locking inner tube, the drainage hole is completely blocked, and the protruding connecting column is exposed at the bottom of the protective outer tube, which facilitates the locking and installation of the anti-clogging filter replacement part.

[0023] (3) The pusher blades proposed in the device of the present invention clean the partition in real time, ensuring that the drainage channel is always unobstructed and avoiding drainage interruption due to blockage.

[0024] (4) The one-way anti-backflow valve proposed in the device of the present invention prevents the drainage fluid from entering the electric negative pressure pump, reducing the probability of pump failure. By setting a replaceable anti-clogging filter module, the cost of clinical medical consumables is greatly reduced compared to replacing the entire drainage device. Attached Figure Description

[0031] The drive unit 36 ​​provides rotational power to the anti-clogging filter chamber 6 to achieve the anti-clogging function.

[0032] The locking ring component 5 includes a locking outer ring 9 and a locking inner tube 10. The locking outer ring 9 and the locking inner tube 10 are fixedly connected, and a sliding ring groove 11 is formed between the locking outer ring 9 and the locking inner tube 10. The inner wall of the locking outer ring 9 is provided with a locking groove 12. The anti-clogging filter tube 6 includes a receiving tube 13 and a protective outer tube 14. The protective outer tube 14 is fixedly connected to the outside of the receiving tube 13. A sliding pusher 15 and a foreign object pusher 16 are fixedly connected inside the receiving tube 13. A mesh 17 is fixedly connected to the bottom surface of the receiving tube 13.

[0033] The sliding pusher 15 includes a pusher tube 18, a bottom support top tube 19, and a support column 20. The pusher tube 18 is fixed to the top surface of the bottom support top tube 19, and the bottom support top tube 19 is slidably sleeved on the outside of the support column 20. The lower end of the pusher tube 18 has drainage holes 23 arranged in a circumferential array. A funnel-shaped drainage plate 24 is fixed to the bottom of the pusher tube 18. The bottom support top tube 19 is fixed to the bottom surface of the funnel-shaped drainage plate 24. The bottom surface of the bottom support top tube 19 has wrapping holes 25. The support column 20 has fitting slots 26 on both sides. A support spring 27 is provided between the top surface of the support column 20 and the bottom surface of the bucket-shaped diverter 24. The support spring 27 is used to support the reset sliding pusher 15. Side protrusions 28 are fixed to both sides of the support column 20. A support base 29 is fixed to the bottom of the support column 20. The support base 29 is fixed inside the receiving cavity tube 13. The enclosing hole 25 slides along the support column 20.

[0034] The foreign object pusher 16 includes a rotating ring 21 and a pusher blade 22. The pusher blade 22 is fixedly attached to the outer wall of the rotating ring 21. The rotating ring 21 is rotatably mounted in the lower end slot 30. A branch connecting post 31 is fixedly attached to the bottom of the rotating ring 21. The bottom surface of the pusher blade 22 slides against the top surface of the partition net 17.

[0035] The upper end of the protective outer tube 14 is fixed to the lower part of the locking outer ring 9, and the lower end of the outer wall of the protective outer tube 14 is fixed to a locking block 32.

[0036] The placement plate 7 has a placement slot 33, the diversion chamber 34 is fixedly connected to the placement slot 33, the outer wall of the diversion chamber 34 is fixedly connected to the mounting slot 35, the locking block 32 is locked in the mounting slot 35, the push drive component 36 includes a drive motor 37 and a rotating disk 38, the rotating disk 38 is fixedly connected to the top of the output shaft of the drive motor 37, the rotating disk 38 has a locking notch 39, the extension connecting post 31 is locked in the locking notch 39, the electric negative pressure pump 8 is connected to the diversion chamber 34 through the pump connecting pipe 40, and a one-way anti-backflow valve 41 is fixedly connected in the pump connecting pipe 40.

[0037] As the rotating disk 38 rotates, it drives the branch connecting column 31 to rotate, and the rotating ring 21 rotates along the lower end slot 30, driving the pusher blade 22 to slide on the top surface of the partition net 17.

[0038] The drainage connector 3 includes a drainage tube 42, an outer tube 43, an inner tube 44, and a locking ring 45. The drainage tube 42 is threaded to the upper end of the outer tube 43. The outer wall of the outer tube 43 is fixedly connected to a locking protrusion 46. The inner wall of the outer tube 43 is fixedly connected to an inner groove 47. A rotating washer 48 is rotatably locked in the inner groove 47. The inner tube 44 is inserted and fixedly connected to the outer tube 43. The outer tube 43 is fixedly connected to the outside of the outer tube 43. The locking ring 45 covers the top of the locking ring 5. The outer tube 43 is axially inserted into the sliding ring groove 11 and then rotated to lock and position itself. The inner diameter of the inner tube 44 matches the outer diameter of the push tube 18.

[0039] The engaging protrusion 46 engages and is embedded in the engaging groove 12 to fix the drainage connector 3 and the engaging ring 5. The engaging block 32 engages and is embedded in the mounting groove 35 to fix the diversion chamber 34 and the anti-clogging filter chamber 6.

[0040] In practical use, such as Figure 8 As shown, in the initial state, the anti-clogging filter replacement 1 is independently sealed and packaged. The support spring 27 supports the bottom support tube 19, so that the top of the push tube 18 is at the same height as the top of the mounting locking ring 5. The push tube 18 is completely wrapped in the locking inner tube 10, the drainage hole 23 is completely blocked, and the outlet connecting post 31 is exposed at the bottom of the protective outer tube 14.

[0041] The negative pressure drainage device 2 is connected to a power source, which provides power to the electric negative pressure pump 8 and the drive motor 37.

[0042] In use, place the new anti-clogging filter replacement 1 in the placement slot 33 of the placement tray 7, insert the outgoing connecting post 31 into the engagement notch 39 of the rotating tray 38, and rotate the engagement block 32 of the outer tube 14 into the mounting slot 35. Place the drainage connector 3 above the placement engagement ring 5, insert the inner tube 44 into the engagement inner tube 10, and insert the outer tube 43 into the sliding ring groove 11. Press downwards, and the push tube 18 is pressed by the inner tube 44, pushing the funnel-shaped drainage plate 24 to compress the support spring. 27. The bottom support tube 19 moves down along the support column 20 until it can no longer be pressed. Then, by rotating and engaging, the engaging protrusion 46 engages with the engaging groove 12 of the engaging outer ring 9. The top of the engaging inner tube 10 contacts the rotating pad ring 48, and the drainage hole 23 is fully exposed in the receiving cavity tube 13. At this time, the installation is completed, the flow path of body fluid is fully opened, the drainage tube fitting 42 is connected to the patient's drainage point, and the fluid collection connector 4 is connected to the fluid collection bag or fluid collection ball. Then, the power is turned on, and the electric negative pressure pump 8 and the drive motor 37 start running synchronously.

[0043] When the electric negative pressure pump 8 is running, the shunt tube 34 is under negative pressure. Through the suction channel, the patient's body fluid flows through the drainage fitting 42 to the push tube 18, passes through the drainage hole 23, and is then guided by the funnel-shaped drainage plate 24 into the receiving tube 13. Since the receiving tube 13 and the shunt tube 34 are separated only by a mesh 17, under negative pressure suction, the body fluid falls from the receiving tube 13 through the mesh 17 into the shunt tube 34. Because the pump connecting pipe 40 is equipped with a one-way anti-backflow valve 41, the body fluid only flows out from the collection connection fitting 4 into the collection bag or collection ball; when clots enter the push tube... At 18:00, after initially passing through the drainage hole 23, which is relatively large and allows the lumps to pass through unimpeded, the lumps fall into the mesh 17 at the bottom of the receiving chamber 13. The mesh 17 completely receives the lumps, and under the operation of the drive motor 37, the rotating disk 38 rotates. Through the extension connecting column 31, the rotating ring 21 is driven to make a circular motion along the lower end slot 30 of the support base 29. The pusher blades 22 continuously sweep the surface of the mesh 17, and the lumps covering the surface of the mesh 17 are pushed and gathered. They continue to move on the surface of the mesh 17 with the pusher blades 22 without obstructing the mesh 17, keeping the flow path unobstructed until the power is cut off.

[0044] When replacing, remove the anti-clogging filter replacement part 1. Without the inner tube 44 being squeezed, the support spring 27 rebounds, the push tube 18 is inserted back into the locking inner tube 10, and the drainage hole 23 is blocked again, so that the clump is completely wrapped in the receiving cavity tube 13 and will not fall out. Then, install the new anti-clogging filter replacement part 1 and put it back into use.

[0045] The above is the overall workflow of this invention. Simply repeat this process the next time you use it.
