1, the principle of clamping is gradual, the beginning of the first drain tube to raise, I usually ask my patients to drain the bag first hang on the shirt button, first hang low, and so on to adapt to the higher button after hanging.
2. When hanging to the highest button is still adaptable, then start clamping the tube. I recommend contacting the daytime first so you can rest well at night. Again, according to the principle of gradual progression, first clamped closed for 1-2 hours to see if you can adapt, and then gradually extend the clamping time.
