Bivona® Inner cannulae help to maintain hygiene of the airway and reduce the risk of a tracheostomy tube blockage. Maintaining hygiene and management of secretions can become difficult without an inner cannula as the removal and changing of the tracheostomy tube may be uncomfortable and traumatic for the patient.  

Portex® Bivona® inner cannula are available in sizes 7.0mm to 9.0mm for use with the Bivona®Tight-to-Shaft cuff, Mid-Range Aire-Cuf® and uncuffed tracheostomy tubes.
