Breather pipe and wash drainage device

The utility model relates to a breather pipe and wash drainage device. The one end and the air supply of this breather pipe are connected, the other end and human abdominal cavity intercommunication, be provided with the filtration on the breather pipe, the filtration is used for flowing through the gas filtration of breather pipe. In the use, there is gas flow in the breather pipe, the filtration can be effectively with probably causing the human impurity that infects to filter in the air to reach and use the safer effect of breather pipe. The utility model provides an it includes air intake part to wash drainage device, air intake part is foretell breather pipe. The utilization is washed drainage device and is washed the in -process of drainage to the patient abdominal cavity, the air from the breather pipe get into wash the reentrant human body of drainage device in, the filter equipment who sets up on the breather pipe can be effectively with probably causing the human impurity that infects filter in the
