Flex D.I.C. Tracheostomy Inner Cannulas

Flex D.I.C. products from Amsino International are replacement inner cannulas designed to work with cuffed dual inner cannula (D.I.C.) tracheostomy tubes. For clinicians, respiratory therapists, and caregivers managing a tracheostomy at home or in a facility, the inner cannula is the part that gets changed most — it's removed, cleaned or discarded, and replaced to keep the airway patent and reduce the risk of occlusion from secretions and mucus buildup.

This collection carries genuine Amsino replacement inner cannulas sized to match the outer tube, which is what matters most when reordering. The Flex D.I.C. Replacement Inner Cannula with a 5 mm tube inner diameter (526060) fits smaller-diameter tracheostomy tubes, while the Flex D.I.C. Replacement Inner Cannula for Cuffed Regular D.I.C. Tracheostomy Tubes at 8 mm I.D. (526090) pairs with standard adult cuffed tubes. Getting the inner diameter right ensures the cannula seats correctly and maintains airflow without compromising the fit of the outer tube.

Because inner cannulas are consumable, most users buy them on a recurring basis rather than as a one-time purchase. Keeping a supply on hand means the airway can be cleared and the cannula swapped promptly the moment secretions accumulate — a routine part of tracheostomy care that helps prevent breathing obstruction and infection. Always confirm the I.D. against the outer tube you're currently using, and match the manufacturer's system, since inner cannulas from one tracheostomy line are not interchangeable with another.

Amsino manufactures a range of respiratory and airway management supplies, and these Flex D.I.C. components are made to the same consistent specifications, so replacements behave predictably from one order to the next. If you're stocking a supply room or a home care kit, order the specific inner diameter your patient requires and reorder before you run low.
