Volymi is a start-up aiming to help paralysed wheelchair users to gain back their independence by developing novel smart wearables. Volymi is developing a non-intrusive urinary catheter monitor that allows the users to keep track of their catheter bag volume for the first time. Previously, the users would have to worry about the bag over-filling and the serious health risks that come with it. Now the user can remain well hydrated and healthy while receiving information about the volume of their catheter bag.
