Blue Line Ultra Inner Cannulas & Tracheostomy Components

For clinicians and caregivers managing a tracheostomy, the inner cannula is the part that gets changed most often — and getting the right size matters. This collection carries genuine Blue Line Ultra disposable inner cannulas designed to fit Blue Line Ultra tracheostomy tubes, giving you reliable, correctly matched replacements for routine airway hygiene.

The inner cannula sits inside the outer tracheostomy tube and can be removed and replaced to clear secretions without disturbing the tube itself. Using disposable inner cannulas supports infection control and cuts down on the cleaning burden, which is why many care settings prefer them for daily management.

Fit is defined by the tube it partners with. We stock cannulas sized for 6 mm Blue Line Ultra tubes (5 mm inside diameter, ref 100/858/060), for 7 mm tubes (6 mm inside diameter, ref 100/856/070), and a 5 mm ID / 6 mm OD option (ref 100/856/060). The key figures to check are the outer tube size and the cannula's inside diameter — matching them keeps airflow adequate and the seal secure. When in doubt, confirm the reference number against the patient's existing tube.

Because these are single-use components, ordering in quantity keeps a steady supply on hand for scheduled changes and unexpected blockages alike. Stock up before you run low, since airway consumables are not something you want to be caught without.
