Welcome to Legend Master!
The inner cannula has a suction catheter attached to the outside. This allows it to remove secretions (accumulated above the cuff) through the fenestration of the Blom Fenestrated Cuffed Tracheosomy Tube. It can be used at a continuous suction of 20-30 mmHg or an intermittent cycled suction at 100-150 mmHg. The suction line cap allows for intermittent manual suctioning when needed.
This cannula comes in 4 sizes and the suction cap is colour coordinated.
