Designed to allow cannula patients to vocalize without the need for finger occlusion

All valves provide one-way airflow using a thin silicone hinged diaphragm that opens on inspiration and closes on expiration.

All valves feature our unique cough-release feature, eliminating valve or tube displacement following a forceful cough or excessive airway pressure.
