A catheter is removed in a series of steps that should be completed by a medical professional, according to WakeMed Physician Practices. To remove the catheter, the balloon port at the end of the catheter must be identified, which has a colored valve with numbers printed on the side.
Once the balloon port valve is identified, it needs to be cut off at the neck of the tube to let the water out, which keeps the balloon inflated. Allow all the water to drain from the tube, which indicates that the balloon is deflated. With a firm pull, remove the entire catheter, and dispose of the tubing and collection bag, explains WakeMed Physician Practices.
