Three-lumen catheters have a flushing cavity that can be flushed with saline or anti-inflammatory drugs, just like an infusion. The catheter was connected to the infusion set with 500 ml of saline, and the bladder was flushed with a three-lumen catheter or the cystostomy tube was flushed with a disposable drainage bag (1000 M1).

To keep irrigation and drainage smooth, disposable drainage bags are often left open. To avoid infection, the irrigation tube and drainage bag should be replaced daily.

First warm the saline solution to flush the bladder. The human body temperature is close to the human body temperature. The infusion port of the three-lumen catheter is completely sterile.
