The funnel end of your catheter is the end opposite of the insertion tip. The drainage funnel is where your urine comes out. First, urine drains from the bladder into the drainage eyelets on the insertion tip. Next, it flows through the catheter tube. Finally, it will leave the catheter and exit through the funnel end.
Catheter funnels are primarily used as an outlet to direct urine flow toward a receptacle like a toilet or a urinal. Catheter funnel ends can sometimes be used as a universal catheter connector to connect the catheter tube to an external receptacle such as a urine drain bag.
