Laryngectomy tubes are used to maintain a patent stoma contracture.
The Provox LaryTubes are available in different lengths. Selecting the optimal length is dependent on the depth and the shape of each individual stoma/trachea. There are various outer diameter in order to achieve optimal fit in different tracheal lumens.
The Provox LaryTubes are designed to be used with the HME cassettes.
Available in three versions:
- The Fenestrated version, designed for use in combination with a voice prosthesis. Several smallfenestrations are preferred over a single large one in order to prevent locking and accidental dislocationof the voice prosthesis. The Provox Brush (7204), normally used for cleaning Provox voice prostheses, isalso suitable for cleaning the fenestrations of the LaryTube.
- The Standard version, made for use without voice prosthesis or when customized fenestration withthe FenestrationPunch is preferred.
- The LaryTube with Ring version, to be worn with an adhesive base plate. Recommended if a cannulais only used during the night or with the Provox FreeHands HME to support the stoma seal.
The Provox LaryButton is a short, self-retaining silicone tracheal cannula. It maintains the opening of the tracheostoma and acts as a holder for other rehabilitation devices of the Provox System including the regular HME cassettes and the Provox FreeHands HME. The main difference between the LaryButton and LaryTube is that the LaryButton is self-retaining in the stoma. Once inserted, it remains in position, taking advantage of the tissue elasticity of the tracheal opening which helps to hold it in place and provide an airtight seal. Of course it also helps to prevent the tracheostoma from shrinking. If needed, wings which are attached to the outer rim of the Provox LaryButton may be used to secure the button with a Provox LaryClip or Provox TubeHolder in order to avoid accidental dislodgement.The Provox LaryButton is particularly well-suited for patients with a circumferential skin fold around the tracheostoma (so called “lip”), however other users may also benefit. To allow for proper selection and sizing, the Provox LaryButton Sizer Kit contains sterilizable and reusable buttons of all lengths and sizes.
Key features:
- The conical shape facilitates a tight fit as it allows the Provox LaryButton to be situated close tothe stoma.
- The Provox LaryButton is intended to be worn in combination with the Provox HME Systemwith optimal fit and stability.
- The Provox LaryButton is constructed from soft silicon material and is atraumatically shaped toreduce negative side-effects such as stoma irritation and bleeding.
