I believe what you have is a PureWick™ System Products or simply put an external urine collection system. They use what they call a External Catheter along with a pump as part of the whole urine collection system.
The pump runs 24/7 to make sure there is vacuum on the tube, less that vacuum the urine is not going into the collection tube so the pump needs to run 24/7.
No pump, no vacuum, no pulling the urine so what happens to the urine? My guess is it runs onto the patient's pad.
Maybe I have this all wrong? I have seen TV commercials for this system.
