It was reported that the problem occurred only with the drainage kit and not the gauze drainage kit but the corresponding part number was given.
During the course of the treatment in the anal area with canal drainage, both the touch pump and the go pump repeatedly displayed blockage alarms with the drainage.
Due to the frequent alarm, the patient suffered from wound healing disorders and the findings worsened.
This led to several additional operating theaters and a longer hospital stay.
The problem lies on the t-vent of the drainage.
