Parts of a Trach Tube
The faceplate, or neck flange, is where the ties or sutures are connected to secure
the tube in place. Here you will also see numbers and letters that indicate what kind of trach tube you have in place as well as the dimensions of the tube.
This is the main body of the tube that is inserted into the trachea. A single cannula tube consists of only one cannula. A dual cannula tube also has an inner cannula.
Dual cannula trach tubes have an inner cannula sits inside the outer cannula and can be removed for cleaning or replacement to help manage secretions.
Standard adult tracheostomy tubes are typically 75mm in length; however, for necks that may be thicker in diameter, longer tracheostomy tube are available.
Some tubes have cuffs that block the airway when inflated by way of the inflation line for patients who require ventilation or have poor swallowing ability. The pilot balloon indicates whether or not there is air in the cuff.
The purpose of the obturator, which is sometimes called a pilot, is to assist with the insertion of the tracheostomy tube. The inner cannula is removed and the obturator inserted which has a blunt tip and cushions the placement of the tube in the trachea to avoid tissue damage. Immediately following placement, the obturator is removed and replaced with the inner cannula.
