[0015] Working principle: When the device is needed, first select a suitable needle and insert the needle into the opening and closing assembly and the connector. The needle will pass through the one-way valve and enter the connector. Then rotate the adjustment shaft. When the adjustment shaft rotates, it will drive gear three to rotate. When gear three rotates, it will drive gear two to rotate. When gear two rotates, it will drive the gear ring to rotate. When the gear ring rotates, it will drive gear one to rotate. At the same time, gear one rotates under the support of the connecting shaft and drives the opening and closing plate to rotate. When the opening and closing plate is centered and clamped, the needle can be fixed, so that the needle can be replaced and installed. Then insert the needle into the affected area for drainage, and the accumulated fluid will flow into the inside of the liquid storage bottle. The observation window can be used to observe the effect of the accumulated fluid inside the liquid storage bottle. When the drainage is completed or the accumulated fluid needs to be released, open the water valve to allow the accumulated fluid inside the liquid storage bottle to flow out from the inside of the water outlet; Rotate the rotating shaft to drive the pawl to leave the tooth end of the ratchet wheel, and then rotate the adjusting shaft to drive gear three to rotate in the opposite direction. When gear three rotates, it will drive gear two to rotate. When gear two rotates, it will drive the gear ring to rotate. When the gear ring rotates, it will drive gear one to rotate. At the same time, gear one rotates under the support of the connecting shaft and drives the opening and closing plate to rotate and open. Then rotate the adjusting shaft to drive the opening and closing plate to rotate until it is completely closed. After use, the needle can be taken out and the entrance of the drainage tube can be closed to prevent dust, other debris, bacteria, etc. from entering the interior of the liquid storage bottle. Close the water valve and turn on the water pump inside the bucket. The water pump draws out the clean water or cleaning liquid inside the bucket through the water pipe into the liquid storage bottle for cleaning. When the cleaning liquid inside the liquid storage bottle is full, it will flow into the drainage tube and the joint. At this time, the opening and closing plate is completely closed. The drainage tube can be manually shaken to clean the inside. Finally, the water valve can be opened to release the cleaned liquid inside the liquid storage bottle.

[0016] The present invention provides a device for drainage treatment of effusion in oncology department, which has the following beneficial effects: 1. The present invention fixes the needle through an opening and closing plate and adopts a replaceable needle design. Medical staff do not need to carry or use a variety of drainage devices of different specifications. They only need to quickly replace the needle when needed to complete the operation. This not only reduces the complexity of the operation process, but also significantly shortens the preparation time, thus gaining more valuable time for clinical treatment.

[0017] 2. The present invention fixes the needle by means of an opening and closing plate. At the same time, due to the presence of a one-way valve, the opening and closing plate can adapt to fix needles of different sizes without leakage. It can adapt to various clinical scenarios by replacing needles of different specifications. This flexibility enables the device to be widely applicable to the needs of different patients, thereby improving the versatility of the equipment.

[0018] 3. The present invention drives the pawl to leave the tooth end of the ratchet wheel by rotating the rotating shaft, and then closes the entrance of the drainage tube, thereby preventing dust, bacteria and other impurities from entering, ensuring that the body fluid sample inside the liquid storage bottle will not be contaminated, especially when further analysis of the properties of the effusion is required, the accuracy and reliability of the test results can be guaranteed.

[0019] 4. The present invention can ensure consistent cleaning effects for the entire device by simultaneously cleaning the liquid storage bottle and the drainage tube, avoiding residual contaminants in a certain part due to separate cleaning, thereby achieving comprehensive cleaning without dead ends and reducing potential infection risks.
