As the fluid accumulation increases, the patient experiences shortness of breath, palpitations and dyspnea, which are increasingly aggravating. To relieve pain in patients with tumors, fluid accumulation is drained.

Most of the existing drainage devices for tumor operation are connected with a puncture element and a negative pressure element at two ends of a container respectively, the negative pressure element provides negative pressure power, and tissue fluid in the thoracic cavity of a patient is drained into the container through puncture. In clinical treatment, the puncture needle is easy to block due to the fact that surgical residues exist in a cavity of an excision part after surgery or tissue blocks are automatically discharged from the body of a patient. After the puncture needle is blocked, the drainage needs to be stopped, the puncture needle is taken out, and the drainage is continued after the puncture needle is replaced, so that the labor intensity of medical workers is increased, the drainage operation time is prolonged, the treatment experience is poor, and the risk of infection of a patient is increased.
