Where can't the urine bag be higher?

Bladder height. Urine bag, also known as waist urine collector, is an auxiliary medical device for collecting urine in vitro, which belongs to the category of medical devices for home care. The urine collection bag should be fixed at the bedside, and should not exceed the height of the bladder, so as to avoid squeezing and prevent urine from flowing back. And when taking urine samples, strict aseptic technical operation is needed. In addition, the catheter should also be kept unobstructed. If it is blocked, it should be sucked out under aseptic technique or washed with sterile physiological saline. Therefore, the urine bag should not be higher than the height of the bladder.
