What is the funnel at the end of a catheter for?

The funnel can be used to attach a urine collection bag to your catheter to measure urine output, or allow you to catheterize when a bathroom isn’t available.

The funnel can also connect to a catheter extension tube to create more length to reach the toilet or urinal. The extension tube is often used by wheelchair users that want to pull up to a toilet and have their catheter reach all the way into the toilet, allowing them to catheterize from their chair.
