Shiley Disposable Inner Cannula provides a convenient hassle-free option for the inner cannula. When you switch the Shiley Inner Cannula, there is no need to clean it, just dispose of it and insert a new one. The inner cannula works with a tracheostomy tube to restore a patient's airway. It also uses a 15mm snap-lock connector. This makes connecting to the tracheostomy tube quick and easy without the need for tape. The cannula uses individual sterilized packaging too. This ensures that your new one is always clean and ready for use at a moment's notice. This inner cannula is not fenestrated, therefore developing a granuloma is eliminated. Also, if aspiration is a concern, a non-fenestrated cannula may be recommended to maintain cuff inflation and protect the airway from saliva and secretions.
