Tube holders (neck straps) are used to keep your tracheostomy tube in place.
It is important that the area around the stoma is kept clean and dry in order to prevent infection. This is why the neck straps must always be changed when they become dirty or wet, or at least once a day. Wet or dirty straps can cause skin irritation and must be avoided under all circumstances.
