Product Literature/Brochure from Boston Medical Products Inc

The Montgomery Speaking Valves are 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. Choose from premium silicone or medical grade plastic (MGP) models. All valves feature our unique cough-release feature, eliminating valve or tube displacement following a forceful cough or excessive airway pressure. Features: Easy-to-use and durable; Low resistance to inspired airflow; Exclusive cough-release feature; 2 models to choose from.
