The male draining jug is ideal for men who have a mobility problem and require to toilet from bed.The jug has a large capacity chamber to hold fluid. Link the system up with a Beambridge 2 litre drainage bag and you then have a system that drains completely into the bag.This keeps the bottle empty and ready for use again.Combine it with the Beambridge adult funnel short and you then have a non return valve helping to prevent the fluid running back on the user.(See photo of Adult Funnel Short )
