[0002] In clinical oncology, tumor fluid accumulation is often encountered. Tumors can cause peritoneal effusion. When the amount of fluid in the peritoneal cavity exceeds 200 ml under pathological conditions, it is called ascites. When the ascites affects the patient's breathing or the patient's abdominal distension symptoms are severe and unbearable, paracentesis can be used to relieve the symptoms.

[0003] The traditional method is to use a rubber hose connected to a standard puncture needle to slowly extract ascites through a syringe connected to it. When extracting ascites and there is a lot of ascites, the doctor needs to frequently remove the syringe, which is a cumbersome operation. After extracting ascites, the plastic indwelling catheter and the sterile drainage bag need to be connected with an intravenous tube to drain by gravity, which requires the doctor to frequently repeat the operation when removing the syringe and connecting the intravenous tube. The operation is cumbersome, and frequent replacement is prone to infection.

[0018] 2. The fluid drainage device for tumor care has a detection port at the bottom of the fluid outlet tube. When it is necessary to sample the accumulated fluid during the drainage process, it is only necessary to insert the sampling test paper into the detection port, so that the accumulated fluid falls directly on the sampling test paper during the dripping process, making sampling more convenient and effective.

[0019] 3. The fluid drainage device used for tumor care can drive the rack to move by driving the pneumatic cylinder, which can then drive the gear to rotate, which can then drive the rotating shaft to rotate, which can then drive the turntable to rotate, which can then drive the slider to move inward, and then drive the clamping block to move inward, so that the clamping block can clamp the fluid collection bottle tightly and fix it, avoiding the problem of the fluid collection bottle being shaken by the outside world during the collection process and causing the accumulated fluid to scatter and contaminate the device, so that the fluid collection bottle is more stably located directly below the liquid outlet pipe, ensuring the stability of the accumulated fluid collection.

[0020] 4. The fluid drainage device used for tumor care can drive the rotating rod to rotate by turning the crank, thereby driving the second bevel gear to rotate, thereby driving the first bevel gear to rotate, thereby driving the threaded rod to rotate, thereby driving the moving rod to move in the sleeve rod, thereby adjusting the height of the device, thereby achieving the ability to adjust the drainage height according to the patient's drainage site to ensure the best drainage effect, and can adapt to doctors of different heights to operate the device, thereby improving the flexibility of the device.

Frequent replacement can easily lead to infection. In addition, in the traditional method, it is inconvenient to sample and test the ascites during the drainage process. The ascites must be collected first, and then part of the collected ascites must be taken for testing, which is inconvenient to operate.

[0026] The rubber stopper 183 is driven upward in the sleeve 181 by pulling the piston rod 182, so that the negative pressure box 12 is in a negative pressure state. Since the negative pressure box 12 and the drainage box 13 are connected, the ascites in the patient's body is drained into the drainage box 13 through the drainage tube 16, and then enters the liquid collecting bottle 22 through the liquid outlet tube 21. The liquid collecting bottle 22 can be replaced and can continue to collect ascites, so that the doctor does not need to remove and replace the syringe when extracting ascites, which is easy to use and avoids infection. In addition, a detection port 211 is opened at the bottom of the liquid outlet tube 21. When it is necessary to sample the accumulated fluid during the drainage process, it is only necessary to insert the sampling test paper into the detection port 211, so that the accumulated fluid falls directly on the sampling test paper during the dripping process, making sampling more convenient and effective.
