A tracheostomy (trach) tube is a curved tube that is inserted into a tracheostomy stoma (the hole made in the neck and windpipe). There are several different brands of tracheostomy tubes, but all have similar parts. The tracheostomy tube consists of three parts: outer cannula with flange (neck plate), inner cannula, and obturator. The outer cannula is the outer tube that holds the tracheostomy open. A neck plate extends from the sides of the outer tube and has holes to attach cloth ties or velcro strap around the neck. The inner cannula fits inside the outer cannula. It has a lock to keep it from being coughed out, and it is removed for cleaning. The obturator fits inside the tube to provide a smooth surface that guides the tracheostomy tube when it is being inserted. There are different types of tracheostomy tubes available and the patient should be given the tube that best suits his/her needs. The frequency of these tube changes will depend on the type of tube and may possibly alter during the winter or summer months. Practitioners should refer to specialist practitioners and/or the manufacturers for advice. Tracheostomy Questions? E-mail tracheostomysupport@jhmi.edu |
