The overnight bag can be connected to the tap on your leg bag and can be used to drain your urine overnight. The bag holds much more urine (2 litres), with some bottles holding up to 4 litres. The overnight bag should be placed in a hanger or positioned to avoid contact with the floor and minimise the chance of pulling on the catheter. The overnight bottle can be placed on the floor and extension tubing is used to connect to the leg bag and are cost effective as they can be used for longer prior to replacing.
Overnight bags and bottles can be rinsed with soap and warm water and re-used.
