1) Pre-flush the connecting pipe with tap water to wet the pipe wall and pre-clean foreign matter.
2) Introduce the cotton thread into the connecting pipe so that it runs through the entire pipe and exposes both ends. Specific method: knot at one end of a cotton thread, 4 to 5 times at the same point, so that the knot can slide freely in the tube and as much as possible, moisten the whole cotton thread, and put the knotted end in front of the knotted part Cut it off. Put the knot in the end of the connecting tube and feed the cotton thread. At this point, the connecting pipe is straight, the incoming end is placed under the tap, the other end is placed in a 500ml empty bottle, and the water is flushed into the pipe while the cotton thread is fed into the pipe, relying on the force of water and gravity. , the cotton thread enters the tube (the front end of the cotton thread is equivalent to the front end of the floating duct, which is more conducive to the cotton thread entering the pipeline) until the entire pipeline is penetrated by the cotton thread. In this process, when the water in the bottle is full, it is poured out in time.
3) Use a cotton thread to fasten the gauze to clean the pipe. Cut off the knot at one end of the knot and fasten the cotton thread entering the pipe and the other cotton thread at the 1/3 and 2/3 of the long axis of the gauze. After wetting the gauze, pull the gauze into the pipe with the cotton thread already in the pipe, and clean the pipe cavity by the friction of the gauze on the pipe wall (the gauze should be 2/3 of the total length of 25cm, half of which is the thickness of the 4cm wide gauze) The other half is the thickness of the 8cm wide gauze. Straighten the pipe, which makes it easier to pull the cotton thread and gauze. While pulling the gauze to clean the lumen, the other cotton thread is brought into the lumen. When the first cotton thread is pulled out The second root also enters the lumen. It is required to pull out the gauze completely, clean the gauze, and then pull the second cotton thread in the opposite direction, and clean the lumen again, and repeat until it is washed.
4) After washing, pull out the cotton thread, rinse the lumen with water, and then put it into the disinfectant for soaking.
