The telescopic rod 6 is externally sleeved with a rebound assembly, which plays a crucial role in the anti-reflux process, providing the necessary reset power for the baffle 8 to ensure the normal operation of the anti-reflux mechanism;
[0037] The rebound assembly includes a spring 7 made of high-quality spring 7 steel, and the spring constant is accurately calculated and designed according to the weight, movement stroke, and required rebound force of the baffle 8, etc., to ensure that the baffle 8 is provided with the right amount of elastic support under various working conditions. The spring 7 is externally sleeved on the telescopic rod 6, and the top of the telescopic rod 6 is fixedly connected with the baffle 8, which is a key element for directly preventing the backflow of the drainage liquid, and is generally made of medical plastic or rubber, having good sealing performance and corrosion resistance. The shape of the baffle 8 is usually circular or square plate, and its size is matched with the channel inside the three-way cock 2, and the edge is finely processed, smooth and tightly contacted with the inner wall of the channel to ensure good sealing performance and smooth sliding.

When the baffle plate 8 is displaced by the pressure of the drainage liquid, the spring 7 is correspondingly stretched or contracted to generate an elastic force, so that the baffle plate 8 can move within a certain range and return to the initial position after the pressure disappears, thereby providing stable power support for the anti-backflow mechanism and ensuring that the drainage liquid can be effectively prevented from flowing back under various conditions.
[0040] Working principle: The drainage bag 1 and related components effectively collect and control the abdominal cavity drainage liquid, ensuring the safety and efficiency of the drainage process. The drainage bag 1 serves as a collection container made of medical-grade plastic material, which has good biocompatibility and strength and can withstand the weight of the drainage liquid. The drainage liquid is delivered to the drainage bag 1 through the drainage tube 4, which is made of soft medical silicone or polyurethane material to reduce irritation to human tissues.
[0041] The three-way cock 2 serves as a key control component that can adjust the flow of the drainage liquid and is provided with an anti-backflow mechanism. When the medicinal liquid enters the inside of the drainage bag 1, the medicinal liquid extrudes the baffle plate 8, which in turn extrudes the telescopic rod 6, so that the spring 7 is deformed, and the medicinal liquid flows into the inside of the three-way cock 2 through the through-hole plate 5. When the pressure dissipates, the spring 7 rebounds, the baffle plate 8 resets, the drainage liquid is prevented from flowing back into the abdominal cavity, and the risk of infection is reduced. The anti-backflow mechanism is realized by a baffle plate and a spring system. The baffle plate is movable under the action of the drainage liquid pressure, and the spring provides a resetting power to ensure that the baffle plate returns to the original position when there is no pressure, thereby effectively preventing backflow.
[0042] The connecting pipe two 10 and the adjusting block 12 jointly control the flow of the drainage liquid, the adjusting block 12 is provided with an adjusting wheel 14, which can adjust the size of the channel of the connecting pipe two 10 according to needs, and accurately control the flow rate of the drainage liquid. By clamping the clamping plate 15 on the bedside and pressing the rotating plate 18, the rotating plate 18 can rotate outside the connecting shaft 17, which in turn drives the clamping rod 19 to fix the connecting pipe two 10. The setting of the dropper 11 enables medical staff to observe the flow of the drainage liquid in real time, ensuring the safety and effectiveness of the drainage process. The overall design ensures effective control and monitoring of the liquid during the drainage process, ensuring the health and safety of the patient.
[0043] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it is still the foregoing each embodiment of the technical solution recorded by modification, or for part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
