Blom-Singer Lo Pressure Voice Prosthesis by InHealth

Inhealth Tech Blom-Singer Low Pressure Voice Prosthesis. 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.
