A hinge 314 is provided at the bottom of the limiting seat 312 and located at the top of the rotating groove 313. A baffle 315 is provided at the bottom of each hinge 314.

[0025] In detail, the fitting plate 31 has a T-shaped structure and the rear end of the fitting plate 31 has an arc-shaped structure that fits the human abdomen. The medical skin-friendly breathable pad 32 and the breathable dressing 33 both have a T-shaped structure. The rear end of the breathable dressing 33 comes with a backing film from the factory.

[0026] The fixing plate 36 has a cuboid structure. The length and width of the fixing plate 36 are greater than the length and width of the pressing cavity 35.

The fixing plate 36 and the fitting plate 31 are integrally formed.

[0027] The slider 39 has a rectangular structure, the body of the pressure plate 311 has a rectangular structure and the output end has a semi-cylindrical structure. When the spring 310 is not under pressure, the outer end of the slider 39 and the side wall of the conforming plate 31 are located on the same plane. The slider 39 and the pressure plate 311 are integrally formed.

[0028] The limiting seat 312 has an L-shaped structure, the length direction of the rotating groove 313 faces the front end, and the hinge 314 allows the baffle 315 to rotate 90 degrees and the left and right baffles 315 to open outwards respectively.

[0029] The loosening mechanism 4 includes a lifting groove 41, a limiting frame 42, a locking spring 43, a pull tab 44, a limiting post 45, and a pull bar 46.

The limiting post 45 is located at the left and right ends of the upper half of the rear end of the pull tab 44. The pull bar 46 is located at the front end of the pull tab 44.

[0030] Both the lifting groove 41 and the pull tab 44 are circular, and the thickness of the lifting groove 41 is greater than the thickness of the pull tab 44. The limiting frame 42 is a cross-shaped structure with a circular center. The limiting frame 42 and the conforming plate 31 are integrally formed. The limiting post 45 is cylindrical.

When the locking spring 43 is not under pressure, the height of each limiting post 45 is the same as the height of the adjacent baffle 315. After the baffle 315 is rotated ninety degrees, the distance between the bottom of the hinge 314 and the top of the pressure plate 311 allows the limiting post 45 to pass laterally. When the locking spring 43 is not under pressure, in terms of length, the end of the limiting post 45 passes through the front end of the rotating groove 313 and does not exceed the rear end of the rotating groove 313.

[0032] The rinsing mechanism 5 includes a rinsing tube 51, a rinsing tube 52, a medical redirecting plastic 53, an injection head 54, and a clamping clamp 55. The rinsing tube 51 is inclined upwards at the front end and is disposed inside the applicator plate 31 and extends through the lower half of the front end of the applicator plate 31.

[0033] The flushing pipe 51 and the drainage pipe 34 are interconnected, and the flushing pipe 51 and the drainage pipe 2 are integrally formed.

[0034] Solution Analysis: 1. Improved ease of use and security Simplified valve operation: Abandoning the traditional mode of frequent valve opening and closing, the drainage tube 2 can be blocked by squeezing the slider 39, and the pull bar 46 can be pulled to unlock and reset. The operation steps are fewer and the time is shorter, reducing the operational burden on medical staff.

[0035] To avoid the risk of air ingress: The built-in through-flow flushing structure, with the flushing tube 52 and drainage tube 2 integrated into one unit, eliminates the risk of loose external interfaces and leakage, structurally reducing the possibility of air entering the pleural cavity and improving the safety of clinical use.

[0036] Anti-accidental locking mechanism: Automatic locking is achieved by the engagement of baffle 315 and limit post 45. After clamping, no continuous force is required, which avoids accidental loosening during operation, resulting in interruption of drainage or failure of flushing.

[0037] 2. Optimized anti-clogging and flushing efficiency Targeted flushing design: The inclined flushing tube 52, combined with the medical-grade redirecting plastic 53, allows the flushing fluid to flow smoothly into the drainage tube 2, precisely flushing the blocked area, improving the flushing patency rate, and reducing the probability of drainage tube blockage.

[0038] The integrated structure reduces blockage points: the flushing tube 51 and the drainage tube 34 are connected in one piece without any additional external joints, which avoids the accumulation of liquid and crusting at the interface, thus forming new blockage points and extending the unobstructed time of the drainage tube 2.

[0039] 3. Enhanced stability and wearing comfort Ergonomic design: The rear end of the fitting plate 31 adopts an arc-shaped structure to fit the abdominal contour. Together with the breathable dressing 33 and the medical skin-friendly breathable pad 32, it achieves double fixation and effectively prevents the device from shifting or falling off.

[0040] Enhanced skin-friendliness: The medical-grade skin-friendly breathable pad 32 and breathable dressing 33 work together to ensure skin breathability, reduce redness, itching or allergic reactions caused by prolonged wear, and improve patient comfort and compliance.

[0041] Multi-dimensional fixation guarantee: In addition to the fixation of the adhesive plate 31, the upper and lower ends of the drainage tube 2 can be further reinforced with breathable adhesive tape to form a stable system of "main body fixation + pipeline auxiliary fixation" to reduce the risk of detachment caused by external force pulling.

[0042] 4. Improved structural reliability and durability Modular integrated design: The clamping mechanism 3, the loosening mechanism 4 and the rinsing mechanism 5 are integrated into the bonding plate 31. The components are integrally formed or stably connected, reducing the number of moving parts and lowering the probability of mechanical failure.

[0043] Elastic reset mechanism: The elastic design of spring 310 and locking spring 43 ensures that the clamping and unlocking actions can be repeated and stably executed, extending the service life of the device and adapting to the needs of long-term clinical drainage.

[0044] Working principle: When flushing the drainage tube is required, first use your index finger and thumb or middle finger and thumb to press the sliders 39 on both sides towards the middle. The sliders 39, in response to the spring 310, drive the pressing plate 311 to press and block the drainage tube 2 in the middle under the limit of the slot 37. During this process, the pressing plate 311 will drive the baffle 315 to contact the limiting post 45. As it continues to move, the limiting post 45 will flip the baffle 315 ninety degrees until it passes the baffle 315. The baffle 315 will spring back to its original position. Release your hand, and the limiting post 45 will clamp and fix the baffle 315.

[0045] Liquid is injected through the injection head 54 and flows downwards through the inclined flushing tube 52 to clean the drainage tube. After cleaning, the pull tab 44 is pulled out through the pull bar 46 in the lifting groove 41, which in turn drives the limiting post 45 to be pulled out to release the clamping plate 311 and allow it to spring back to its original position. Finally, you can release your hand. The operation is simple and quick.

[0046] In addition, the drainage tubes 2 at both ends of the applicator 31 can be fixed using existing breathable dressings. The applicator 31 is fixed to the abdomen below the chest cavity. The end of the applicator 31 that contacts the skin has an arc-shaped structure, which better conforms to the shape of the abdomen, thus increasing stability. Furthermore, the breathable dressing 33, with its backing film removed, further increases stability, preventing the device from shifting or easily dislodging due to external force. The medical-grade skin-friendly breathable pad 32, combined with the breathable dressing 33, ensures that the skin in contact with the applicator can breathe freely, preventing redness, itching, or allergies even after prolonged use.

[0047] Technical effects of implementing this solution: This solution, through its integrated structural design, convenient clamping and unlocking mechanism, directional flushing function, and ergonomic fixation scheme, comprehensively addresses the core issues of existing chest drainage tube anti-clogging flushing devices from four dimensions: ease of operation, clinical safety, drainage patency, and patient comfort. These issues include cumbersome valve operation, easy leakage and blockage at the interface, risk of air ingress, unstable fixation, and skin allergies. It not only improves the clinical operation efficiency of medical staff but also reduces the risk of complications for patients, making it a safer, more efficient, and more comfortable chest drainage tube auxiliary flushing device.

[0048] The present invention comprises: 1-transparent dressing; 2-drainage tube; 3-pressing mechanism; 31-adhesive plate; 32-medical skin-friendly breathable pad; 33-breathable dressing; 34-drainage tube groove; 35-pressing cavity; 36-fixing plate; 37-groove; 38-slide groove; 39-slider; 310-spring; 311-pressing plate; 312-limiting seat; 313-rotating groove; 314-hinge; 315-baffle; 4-releasing mechanism; 41-lifting groove; 42-limiting frame; 43-locking spring; 44-pull tab; 45-limiting post; 46-pull strip; 5-rinsing mechanism; 51-rinse The components—52-rinse tube, 53-medical redirecting plastic, 54-injection head, and 55-clamping clamp—are all general-purpose standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem this invention solves is that existing chest drainage tube anti-clogging rinsing devices require frequent valve opening and closing, and the rinsing ports are mostly externally connected, making the connections prone to loosening, leakage, and blockage. Furthermore, the large number of valves and interfaces in these devices easily leads to leakage of fluid, air, and air entering the chest cavity, posing clinical safety risks. This invention, through its integrated structure, convenient clamping and unlocking, directional rinsing, and ergonomic fixation design, solves the core problems of existing devices from the dimensions of operation, safety, patency, and comfort, making it a safer, more efficient, and more comfortable chest drainage tube anti-clogging rinsing auxiliary device.
