Description

Disposable detachable dual-purpose abdominal cavity flushing drainage tube Technical Field The utility model relates to the technical field of drainage tubes, in particular to a disposable detachable dual-purpose abdominal cavity flushing drainage tube. Background The abdominal surgery involves the risks of weeping, anastomotic stoma leakage and the like in the operation, and particularly, the anastomotic stoma leakage is easy to accumulate liquid, infect necrosis and corrode blood vessels to cause massive hemorrhage. Furthermore, secondary operation is needed, the impact on a patient is large, and large economic pressure can be generated, and the primary solution to solve the problems is to use the abdominal cavity drainage tube to keep the abdominal cavity unobstructed for drainage. Because the effusion solid matter is more, very easily cause the drainage tube to block up in drainage process, so can insert negative pressure equipment at the drainage port of drainage tube generally and carry out drainage. However, if the pressure of the negative pressure equipment is controlled improperly or the blockage is serious, the pressure in the drainage tube is in a vacuum state for a long time, and once the drainage tube is dredged under the condition, the huge pressure difference can damage tissues in the abdominal cavity, the drainage tube is blocked, and the recovery of a patient is affected. In addition, the main drainage tube is placed in the operation, and if the drainage tube is blocked and can not be used, the replacement of the pipeline is difficult. In the prior art, in order to solve the above problems, there are means such as a flushing tube arranged outside the drainage tube. However, in practical use, the flushing liquid in the flushing pipe is flushed into the abdominal cavity so as to dilute the abdominal cavity effusion.
