Sklar's Jackson Original Style Tracheostomy Tube consists of one obturator, an inner cannula, and an outer cannula. These three pieces work together to ensure that you can breathe properly following a tracheal incision. The obturator is used to safely and gently place the outer cannula into the incision and into the trachea. The outer cannula is the part of the device which keeps the actual incision in the neck open. The neck plate, which is attached to the outer cannula, is where the side slots are located for tying or strapping the tube around the patient's neck, as well as part of the locking mechanism. Once the outer cannula is secured, the obturator is removed and the inner cannula is inserted. The Jackson original style tube features a lock on the faceplate that protrudes upward slightly and swivels over the inner cannula to secure it in place. The original style inner cannula is also designed with "wings" on each side that are used for its removal. This product is the #00 tracheostomy tube. It is curved with an outer cannula diameter of 3mm, and inner cannula diameter of 1.8mm, and an overall length of 33mm.
