Provox voice prosthesis

In 1990 the first Provox® voice prosthesis was introduced on the market. The Provox® voice prosthesis is bi-flanged and made of medical grade silicone rubber. The prostheses are used worldwide, which is demonstrated by many publications in different languages.

Provox HME System

After a total laryngectomy the patient breathes in and out through the tracheostoma in the neck. Therefore the nasal functions of warming, humidifying and filtering the inhaled air are lost, as well as the upper airway resistance. An HME has three physical properties: 1) Heat and moisture exchange capacity; 2) Resistance and 3) Filtering particles. This literature review concerns the Provox HME System and related accessories manufactured by Atos Medical.
