2-piece urostomy pouch integrates mechanical coupling with extra reassurance. The pouch is fixed securely to the baseplate by a mechanical coupling system. An audible ‘click’ confirms the secure locking of the pouch to the baseplate. The bag’s secure and easy to use outlet is easy to handle, and design of the pouch ensures there is no residual urine left in the pouch after emptying. A non-return valve prevents the urine from washing over the stoma, reducing the risk of urinary infections.
