External drainage of effusion is a drainage method commonly used in medicine. It inserts 1 or 2 porous catheters connected to the drainage bag into the wound cavity or body cavity through surgery, and automatically drains the effusion in the cavity. Its advantage is that the quality of drainage is very high, it is beneficial to prevent infection, it can relieve the compression of nearby organs and blood vessels, improve symptoms, and promote wound healing, so it is widely used clinically. After reviewing multiple literatures, a common conclusion was reached: intermittent and quantitative drainage is very important during the drainage of effusion. For example, massive and rapid drainage of the pleural cavity can lead to reexpandable pulmonary edema and mediastinal swing; excessive drainage of cerebrospinal fluid can lead to intracranial hemorrhage and chronic subdural hematoma; excessive drainage of the abdominal cavity can lead to a sudden drop in abdominal pressure and induce hepatic encephalopathy, etc.

At present, the clinical control of drainage volume still relies on manual monitoring. Since the drainage bag must be hung at a low place, it is not easy to observe the drainage volume, which causes excessive tension for patients and family members, increased workload for nurses, and even negligent monitoring or improper methods. Various reasons lead to complications such as excessive drainage, pipeline prolapse, effusion reflux infection, etc. Although in recent years there have been some inventions and creations in pipeline fixing, puncture technical equipment, pipeline connection, anti-backflow, drainage bag precision calculation, negative pressure drainage, drainage receiving device, etc., someone once designed a device that can control the drainage speed. The drainage bag of the regulator, but at present, the control means for the intermittent drainage of the effusion is still a blank at home and abroad, and there is no equipment that can achieve self-drainage control.

Considering the clamping effect, the above-mentioned pipeline clamping hole is a structure that is closed and opened at the same time.
