Changes and modifications of tracheostomy tubes

Collars for tubes

Many tracheostomy patients need to have a collar fitted on the tube/cannula. The collar needs to have a larger diameter than the tube itself, to keep it sealed tight.
Over time the stoma changes its shape due to the pull of the tubes. This often causes leaking of air and saliva, in which case a collar would eliminate the problem. A collar can also be used by patients who would like to reduce the diameter of the tube/inner cannula in order to be able to speak properly.

Shortening and modification of the curvature of trach tubes

If a patient needs a tube shortened, simply cutting the tube can cause damage to the mucous membrane. Making sure that the tube’s edge is soft and polished, requires the correct equipment and machines, a bit of an effort, however the correct procedure can eliminate the risk of damaging the mucous membranes.
An unsuitable curvature of the tube/inner cannula can also irritate the membranes, especially by the lower edge of the tube/inner cannula. The radius of most tubes on the market can be modified.
Another important aspect of trach tubes is the departure angle to the connecting tube, as the angle affects how much the tube edge rubs up against the mucous membrane. Typically, the joints (elbows) are at a 90-degree angle, which in almost all cases leads to the inner cannula hitting the sternum and a subsequent pull on the tube. This leads to the tube’s lower edge hitting the front of the trachea.
To combat these problems, KRC designed elbows which are at a 70-degree angle (also called a Chinese chimney), counteracting the above-mentioned side effects

Fenestration

KRC can fenestrate most types of tracheostomy tubes available.
