Description

Technical Field

[0001] The invention relates to the technical field of thoracic surgery anti-blocking equipment, and in particular to a multifunctional thoracic surgery anti-blocking drainage device. Background Art

[0002] Thoracic surgery focuses on the study of organs within the chest cavity, mainly including the diagnosis and treatment of lesions of the esophagus, lungs and mediastinum. Pulmonary surgery and esophageal surgery are its main research directions. Closed chest drainage is a commonly used treatment method in the field of cardiothoracic surgery. Its main purpose is to discharge the gas and fluid in the patient's chest cavity in time to promote the reopening of lung tissue and restore its function.

[0003] During the implementation of closed chest drainage, one end of the drainage tube needs to be punctured into the chest cavity, and the other end is connected to a lower water seal bottle. In this way, the gas or liquid in the chest cavity can be discharged smoothly through the drainage tube, thereby achieving the treatment purpose. This treatment method is widely used in the drainage of hemothorax and pneumothorax and after thoracotomy, and plays a very important role in the treatment of the disease.

[0004] However, when the chest cavity is invaded by pathogens such as bacteria and viruses, it is easy to induce an inflammatory response, which will increase the viscosity of the pleural effusion and may even form empyema. During the closed chest drainage process, as these viscous or purulent effusions flow along the drainage tube under the suction of the water seal bottle, due to their high viscosity, the friction force adsorbed on the drainage tube will gradually increase, resulting in a slowdown in the drainage speed and even blockage of the drainage tube. Therefore, when performing closed chest drainage, it is necessary to pay close attention to the properties and drainage speed of the drainage fluid, take timely measures to prevent blockage of the drainage tube, and ensure the smooth progress of the treatment. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that when the chest cavity is invaded by pathogens such as bacteria and viruses, an inflammatory reaction is easily triggered, resulting in an increase in the viscosity of the pleural effusion and even the formation of empyema. During the closed chest drainage process, as these viscous or purulent effusions flow along the drainage tube under the suction of the water seal bottle, due to their high viscosity, the friction force adsorbed on the drainage tube will gradually increase, thereby causing the drainage speed to slow down or even cause the drainage tube to become blocked. Therefore, when performing closed chest drainage, it is necessary to pay close attention to the properties and drainage speed of the drainage fluid, take timely measures to prevent the drainage tube from being blocked, and ensure the smooth progress of the treatment.

[0028] Brine dilution and anti-blocking: The rotation of the mounting rod drives the sealing plate to move, releasing the brine in the sealing cover, and diluting the viscous accumulated liquid through the stirring of the blades, effectively preventing the connecting pipe from being blocked.

[0029] Drainage acceleration mechanism: The linkage between the contact plate and the blade makes the L-shaped plate and the toggle plate move periodically.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] like Figure 1-Figure 8 As shown, the present invention provides a multifunctional thoracic surgery anti-blocking drainage device: comprising a water seal bottle 10, the top of the water seal bottle 10 is connected to a connecting tube 11, the connecting tube 11 is connected to a drainage tube 12 through an anti-blocking component 20, and further comprising: an adjusting component 30 assembled inside the anti-blocking component 20;

[0047] like Figure 1 , Figure 2 As shown, the anti-blocking assembly 20 includes an anti-blocking box 21 connecting the connecting pipe 11 and the drainage pipe 12, a micro motor 22 is installed at the bottom of the anti-blocking box 21, the output shaft of the micro motor 22 passes through the anti-blocking box 21 and is connected to a rotating shaft 23, a plurality of blades 24 are connected to the outer periphery of the rotating shaft 23, and a plurality of liquid flow ports 241 are opened on the side of each blade 24;

[0048] In order to prevent the connection tube 11 from being blocked, as the water seal bottle 10 works, the effusion in the pleural cavity will smoothly flow into the anti-blocking box 21 through the drainage tube 12. In order to handle the viscous effusion, a micro motor 22 is specially equipped. After the micro motor 22 is started, it will drive the rotating shaft 23 to rotate. The rotation of the rotating shaft 23 will drive the blades 24 to rotate synchronously, so as to fully stir the viscous effusion flowing into the anti-blocking box 21.

[0049] This stirring process plays a vital role in the smooth flow of the effluent. Firstly, through the stirring of the blades 24, the liquid part in the viscous effluent can flow more smoothly, reducing the risk of blockage. Secondly, the shear force generated by the stirring helps to break the agglomeration or viscous structure that may exist in the viscous effluent, further improving the fluidity of the effluent. In addition, with the stirring of the blades 24, the components in the viscous effluent can be more evenly distributed, eliminating possible concentration gradients or precipitation.

[0050] It is worth mentioning that a liquid flow outlet 241 is specially provided on the blade 24. This liquid flow outlet 241 not only facilitates the flow of liquid, but more importantly, the bubbles generated during the stirring process can be effectively broken through this liquid flow outlet 241, thereby preventing the generation and accumulation of bubbles.

[0051] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the adjustment component 30 includes a pusher installed on the outer periphery of the rotating shaft 23, and the pusher includes a connecting block 31 fixedly connected to the outer periphery of the rotating shaft 23. Two connecting rods 311 are connected to the side of the connecting block 31 away from the rotating shaft 23. The outer periphery of the connecting rod 311 is slidably connected with an abutment block 312, and a telescopic spring 313 is connected between the connecting rod 311 and the abutment block 312. The inner wall of the anti-blocking box 21 is fixedly connected with two symmetrical limit plates 32. The two limit plates 32 are slidably connected with an adjustment plate 323 through an inner groove 321 opened inside. One side of the two adjustment plates 323 is provided with an oblique angle 324. The interior of the adjustment plate 323 is provided with an arc cavity. The limit plates 32 The inner wall of the arc rod 326 is connected, and the outer circumference of the arc rod 326 is sleeved with an arc spring 327. The two ends of the arc spring 327 are fixedly connected to the limit plate 32 and the adjustment plate 323 respectively (the arc rod 326 and the arc spring 327 are only arranged in the adjustment plate 323 connected to the first extension block 33). A plurality of moving grooves 322 are opened on the outer circumference of one of the limit plates 32, and the other limit plate 32 is only opened with a moving groove 322 that cooperates with the movement of the second extension block 35. A contact block 325 is connected between one of the adjustment plates 323 and the abutment block 312, and a steering member is connected between the two adjustment plates 323 through the first extension block 33 and the second extension block 35.

[0052] The rotation of the rotating shaft 23 not only stirs the viscous effusion, but also triggers the automatic adjustment mechanism of the opening size of the connecting pipe 11. When the rotating shaft 23 starts to rotate, the connecting block 31 also rotates and cooperates with the abutting block 312. The abutting block 312 pushes the contact block 325 in contact with it to move along the moving groove 322. This action further causes the linkage movement of the adjusting plate 323, and the arc spring 327 is stretched to store potential energy.

[0053] Once the contact block 325 stops moving under the restriction of the moving groove 322, the connecting block 31 continues to rotate and drives the abutting block 312 to slide along the inclined surface of the contact block 325. This process compresses the telescopic spring 313, and finally causes the abutting block 312 to break away from the abutting state with the contact block 325.

[0054] As the abutment block 312 is disengaged, the previously stretched arc spring 327 begins to rebound, and its force pulls the adjustment plate 323 back to its original position. Since a steering member is provided in the anti-blocking box 21, the two adjustment plates 323 can move inward synchronously, thereby realizing precise adjustment of the opening size of the connecting pipe 11;

[0055] This design cleverly promotes the drainage of necrotic tissue and exudate in the wound surface through the intermittent suction "suction-stop" cycle. By continuously adjusting the opening size of the connecting tube 11, the system can ensure that the drainage process is more thorough and effective.

[0056] It is worth mentioning that one side of the adjustment plate 323 is designed with an angle 324. When the two adjustment plates 323 move relative to each other, causing the opening of the connecting tube 11 to gradually decrease, the accumulated fluid will flow smoothly into the connecting tube 11 along the angle 324. At the same time, as the opening gradually decreases, the angle 324 also accelerates the flow rate of the accumulated fluid, further enhancing the fluidity of the accumulated fluid, ensuring that the accumulated fluid can maintain a high flow rate throughout the drainage process, thereby improving the drainage efficiency.

[0057] like Figure 2 , Figure 3 As shown, the steering member includes a collar 34 installed inside the anti-blocking box 21, the outer periphery of the collar 34 is rotatably connected to the first rotating gear 341 and the second rotating gear 346, the inner wall of the anti-blocking box 21 is fixedly connected to the first positioning column 342 and the second positioning column 344, the outer periphery of the first positioning column 342 is rotatably connected to the first connecting gear 343, the outer periphery of the second positioning column 344 is rotatably connected to the second connecting gear 345, the first connecting gear 343 is meshedly connected to the first rotating gear 341, the second connecting gear 345 is meshedly connected to the second rotating gear 346, and the first connecting gear 343 is meshedly connected to the second connecting gear 345;

[0058] As the adjustment plate 323 moves, the first extension block 33 is driven to move together, and the first extension block 33 drives the first rotating gear 341 to rotate along the outer circumference of the ring 34. As the first rotating gear 341 rotates, the first connecting gear 343 is driven to rotate. When the first connecting gear 343 rotates, the second rotating gear 346 is driven by the second connecting gear 345 to rotate in the opposite direction of the first rotating gear 341, thereby facilitating the control of the size of the opening of the connecting pipe 11.

[0059] like Figure 1 , Figure 2 , Figure 6 As shown, the top of the anti-blocking box 21 is connected to a dilution assembly 40, and the dilution assembly 40 includes a sealing cover 42 installed on the top of the anti-blocking box 21 and a brine tank 44 installed on the top of the sealing cover 42. The top of the rotating shaft 23 is connected to a mounting rod 41, and the outer periphery of the mounting rod 41 is fixedly connected to an abutment sleeve block 411, and the top of the abutment sleeve block 411 is connected to an abutment ball 412. The inner wall of the sealing cover 42 is fixedly connected to a fixed disk 43, and the surface of the fixed disk 43 is provided with a liquid leakage port 431 and a lifting port 432. The fixed disk 43 and the sealing cover 42 are connected by a sealing member, and the sealing member includes two fixedly installed on the inner wall of the sealing cover 42. A fixing rod 433, the outer periphery of the two fixing rods 433 is connected with a sealing plate 438, and the bottom ends of the two fixing rods 433 pass through the sealing plate 438 to be connected with the fixing plate 43, the outer periphery of the two fixing rods 433 is sleeved with a pressure spring 434, the sealing plate 438 is connected to the lifting port 432 through a tilting block 436 (when the tilting block 436 rises with the abutment of the abutment ball 412, it will also be in the lifting port 432 and will not move out of the lifting port 432), the bottom of the sealing plate 438 is connected with a sealing column 437, and the top of the sealing plate 438 is connected with a blocking rod 435 for blocking the connection between the sealing cover 42 and the brine tank 44;

[0060] As the rotating shaft 23 rotates, the mounting rod 41 is also driven to rotate synchronously. During this process, the abutting sleeve block 411 on the mounting rod 41 pushes the abutting ball 412 to make it contact with the tilting block 436. This contact force causes the tilting block 436 to move along the trajectory of the lifting port 432.

[0061] As the tilting block 436 moves, it pushes the sealing plate 438 fixed on the fixing rod 433. After being pushed, the sealing plate 438 moves along the outer circumference of the fixing rod 433 and squeezes the pressure spring 434. This squeezing action causes the plurality of sealing columns 437 to move out of the liquid leakage port 431, thereby allowing the saline in the sealing cover 42 to flow into the anti-blocking box 21 through the liquid leakage port 431.

[0062] Once the salt water flows into the anti-blocking box 21, the stirring action of the blades 24 will further stir and dilute the viscous effluent, thereby effectively preventing the connection pipe 11 from being blocked;

[0063] At the same time, as the sealing plate 438 rises, it also drives the blocking rod 435 to rise together. The rising action of the blocking rod 435 blocks the connection between the sealing cover 42 and the brine tank 44, thereby controlling the balance of the brine amount in the sealing cover 42;

[0064] When the rotating shaft 23 continues to rotate so that the abutment ball 412 no longer contacts the tilting block 436, the pressure spring 434 will exert its rebound effect to push the sealing plate 438 to reset. During the resetting process, the sealing column 437 will reseal the leakage port 431 to prevent further outflow of brine. At the same time, the blocking rod 435 will also drop to open the connection between the sealing cover 42 and the brine tank 44, so as to facilitate the replenishment of the brine in the sealing cover 42. The brine in the brine tank 44 can be added through its opening to ensure the continuous operation of the dilution component 40.

[0065] like Figure 2 , Figure 7 , Figure 8 As shown, the inner wall of the anti-blocking box 21 is connected with a toggle assembly 50, which includes two fixed columns 51 fixedly installed on the inner wall of the anti-blocking box 21 and close to the drainage pipe 12, the outer peripheries of the two fixed columns 51 are slidably connected with a contact plate 52 in contact with the blade 24, the outer peripheries of the fixed columns 51 are sleeved with a pressure spring 53, the side of the contact plate 52 close to the drainage pipe 12 is connected with an L-shaped plate 54, the two sides of the L-shaped plate 54 are connected with toggle members, the toggle members include square blocks 55 installed on both sides of the L-shaped plate 54, the inner walls of the square blocks 55 are connected with a center column 56, the outer periphery of the center column 56 is rotatably connected with a toggle plate 57, and the inner walls of the square blocks 55 are connected with a limiting plate 58 for limiting the rotation stroke of the toggle plate 57;

[0066] In order to optimize the flow efficiency of the viscous effusion in the drainage tube 12 and ensure that they can enter the anti-blocking box 21 more quickly, as the blades 24 rotate in the anti-blocking box 21, they will come into contact with the contact plate 52, and this contact will cause the contact plate 52 to slide along the outer periphery of the fixed column 51 and compress the pressure spring 53. At the same time, the L-shaped plate 54 connected to the contact plate 52 will also be pushed to move together;

[0067] During the movement of the L-shaped plate 54, the two sliding plates 57 which were originally in the expanded state will be affected by the flow of the effusion and gradually shrink, and finally fit tightly with the L-shaped plate 54. This shrinking state ensures that there will not be too much resistance to affect the flow of the effusion during the movement of the L-shaped plate 54.

[0068] When the blade 24 is no longer in contact with the contact plate 52, the pressure spring 53 starts to play its reset role, pushing the contact plate 52 and the L-shaped plate 54 connected thereto back to the initial position. As the L-shaped plate 54 is reset, the two toggle plates 57 come into contact with the effluent at the inclined toggle angle and gradually expand under the flow of the effluent.

[0069] The unfolded toggle plate 57 can effectively toggle the accumulated fluid, which can increase the flow rate of the accumulated fluid and help it enter the anti-blocking box 21 more smoothly. Through this design, not only the flow efficiency of the accumulated fluid is improved, but also the blockage of the drainage tube 12 is effectively prevented, ensuring the smooth progress of the drainage process.

[0070] Working principle: After starting the micro motor 22, the rotating shaft 23 starts to rotate, driving the blades 24 to stir the viscous accumulated liquid flowing into the anti-blocking box 21. At the same time, as the rotating shaft 23 rotates, the connecting block 31 drives the abutting block 312 to interact with the contact block 325. The contact block 325 moves under the guidance of the moving groove 322 and stretches the arc spring 327 to store potential energy. When the contact block 325 stops moving, the abutting block 312 slides along the inclined surface, compresses the telescopic spring 313 and breaks away from the contact block 325. At this time, the arc spring 327 releases energy and pushes the adjustment plate 323 to move inward synchronously through the steering member, thereby accurately adjusting the opening size of the connecting pipe 11.

[0071] At the same time, the rotating shaft 23 also drives the mounting rod 41 to rotate, so that the abutment sleeve 411 pushes the abutment ball 412 to contact the tilting block 436, which prompts the tilting block 436 to move along the lifting port 432, and then pushes the sealing plate 438 to move along the fixing rod 433 and squeeze the pressure spring 434. This process causes the sealing column 437 to move out of the leakage port 431, allowing the brine in the sealing cover 42 to flow into the anti-blocking box 21, and the blades 24 continue to stir and dilute the viscous accumulated liquid to prevent the connecting pipe 11 from being blocked. The entire device realizes the integrated functions of automatic stirring, opening adjustment and brine replenishment.

[0072] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
