Pleural effusion is a common clinical disease, adopts puncture and aspiration treatment, and aims to: the pressure of the lung, the heart and the blood vessels is relieved as soon as possible, the respiration of a patient is improved, so that the fibrin deposition, the pleural thickening, the impaired lung function and the like are effectively prevented, and after puncture and fluid extraction, the toxic symptoms of the patient can be effectively relieved, and the compressed lung expansion function is comprehensively improved. The pleural effusion drainage operation is adopted for treatment, the operation has the characteristics of simplicity and convenience in operation, short time consumption, small wound, high safety and the like, and the pleural effusion drainage operation only needs one-time puncture, so that the tissue damage can be effectively avoided, the pain born by a patient is greatly reduced, the adaptability of the operation is stronger (the applicable age is wider), and the generation of complications such as pulmonary edema, pneumothorax, pleural reaction and the like can be timely avoided; is a clinical means superior to the conventional thoracentesis fluid-pumping treatment of pleural effusion and has higher application value. However, when the drainage volume is too large or the drainage speed is too fast for one time, the risk of the renatured pulmonary edema is generated, and the patient can have obvious complications of chest distress, palpitation, cold sweat and the like.

The fluid accumulated in the abdominal cavity is commonly referred to as ascites. Is commonly seen in liver cirrhosis, portal hypertension, peritoneal metastasis, nephrotic syndrome, pancreatic ascites or tuberculous peritonitis, and partial cardiovascular diseases such as heart failure; they are usually classified into leaky, exudative and bloody ascites. When the ascites is generated too much and cannot be absorbed by the patient, abdominal puncture external drainage is needed; some patients need to be washed in the abdominal cavity or injected with drugs for treatment; meanwhile, when the drainage is too fast and excessive, the patient can have corresponding complications, the discomfort of the patient is aggravated, the treatment effect is influenced, and even the life is threatened; for example, in the case of ascites due to cirrhosis, the peritoneal drainage should not be too fast or too rapid to avoid electrolyte disturbance and loss of plasma proteins, and even to induce hepatic encephalopathy and hepatic coma; therefore, a flow diverter with adjustable speed and anti-backflow is needed.
