Coloplast SenSura Mio - 1-Piece Maxi Pre-Cut Closed Ostomy Bag is a closed end pouch which means once it is full it doesn't need be emptied and cleaned out. You simply remove the ostomy bag and then discard it. The Sensura Mio Maxi is a larger sized ostomy pouch, so you can wear it for a longer period. The neutral gray cloth-like material covering the bag is comfortable against the skin and is more discreet than standard tan pouches. Sensura Mio has a full-circle filter which helps the filter release gas which helps stop the ostomy bag from ballooning. This is a one-piece ostomy system so there is no need to buy a separate ostomy wafer. The attached ostomy wafer is an elastic skin barrier designed to move with your body and stay in place, even over skin folds, scarring, and hernias. The pouch is opaque which makes it more discreet however it does come with an easy to see inspection window, so you can monitor your output without having to open the pouch. This maxi length pouch is 8 1/2" inches long and available in pre-cut wafer sizes, 1 3/8" and 1 3/16".
