  • Where can I find the size markings to indicate the size of the inner cannula?

    The size markings are on the tracheostomy tube flange, inner cannula tube and pack labels.

  • Which tracheostomy tubes are compatible with the Bivona® Inner Cannula?

    Size 7.0mm - 9.0mm Bivona® TTS™ (tight to shaft) cuff, Mid-Range Air-Cuf® and Uncuffed tracheostomy tubes.

  • What is the MRI classification of the Bivona® Inner Cannula?

    The Bivona® Inner Cannula is MR-Safe. However, users should refer to the instructions of the Bivona® tracheostomy tube instructions for their MR compatibility.

  • Do I need to use lubricating jelly on the Bivona® Inner Cannula?

    No. Using lubricating jelly may occlude the inner cannula and prevent it from being retained in the tracheostomy tube.

    The Bivona® Inner Cannula is for single patient use. It can be used for 29 days, and cleaned up to 400 times in that time period.

  • How do I clean the Bivona® Inner Cannula?

    Daily cleaning of the inner cannula is recommended, or whenever the inner cannula becomes contaminated by mucus or secretions. Do not use any abrasive cleaning implements. Use only sterile water or saline with the recommended cleaning swab, product code BICSWB. Do not use this swab to clean the tracheostomy tube. Inner Cannula (Inner cannulae) should not be cleaned using other methods e.g. autoclave or dishwasher.

  • Is the Bivona® Inner Cannula just for hospital use?

    No, the Bivona® Inner Cannula can be used at home too, allowing the patient continuity and familiarity with their tracheostomy tube after they have left hospital.

  • What size Bivona® Inner Cannula should I use with my tracheostomy tube?

    You should use the same size Bivona® Inner Cannula as the tracheostomy tube you are using. So for a size 7.0mm tube a size 7 Bivona® Inner Cannula should be used.

  • What is the shelf life of the Bivona® Inner Cannula?

    The Bivona® Inner Cannula has a shelf life of 3 years.

  • What is different about the Bivona® Inner Cannula?

    The Bivona® Inner Cannula is the first inner cannula to market for use with silicone tracheostomy tubes. It is fully flexible and pliable and is manufactured from PTFE which means secretions are less likely to adhere to it.

  • Why would I want to use an inner cannula?

    Using the inner cannula will assist in maintaining a clear and patent patient airway.
