Inhealth Tech Blom-Singer® Low Pressure Voice Prosthesis 20Fr, 12mm L
The Low Pressure 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. Like the Duckbill Voice Prosthesis, the one-way valve protects the airway during swallowing and opens under positive pressure so that air crosses into the esophagus to produce voice. The Low Pressure is a patient-maintained device; the patient may insert, remove and clean the device independently.
