PassyMuir

Invented by a patient named David Muir, the Passy-Muir® Tracheostomy & Ventilator Swallowing and Speaking Valve is a simple medical device used by tracheostomy and ventilator patients. When placed on the hub of the tracheostomy tube or in-line with the ventilator circuit, the Passy-Muir Valve redirects air flow through the vocal folds, mouth and nose enabling voice and improved communication.
