Inhealth Tech Blom-Singer Low Pressure Voice Prosthesis is a silicone one way flapper valve prosthesis designed for placement in a passage between the trachea and the esophagus for voice restoration following laryngectomy. The one way valve protects the airway during swallowing and opens under positive pressure so that air crosses into the esophagus to produce voice. It is a patient maintained device so that the patient may insert, remove and clean the device independently.
