Cuffless Fenestrated Tube (CFN) is designed for pulmonary hygiene and, when used in conjunction with the Decannulation Plug (DCP), directs breathing through the upper airway. Fenestrated inner cannula aids weaning and speaking. Inner cannula with integral 15mm twist-lock connector permits connection of ancillary equipment and is translucent for easy inspection. Smooth, rounded-tip obturator facilitates insertion. Low profile inner cannula minimizes tube profile for long term care. Swivel neck flanges improve patient comfort. Designed for use to bypass upper airway obstructions, provide long term ventilation, support and/or manage tracheal/bronchial secretions.
