[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.
