InHealth Tech Blom-Singer Duckbill Indwelling Voice Prosthesis

InHealth Tech Blom-Singer Duckbill Indwelling Voice Prosthesis is a patient-changeable, one-way slit valve prosthesis that the patient may insert, remove, clean and reinsert. The one-way slit valve prosthesis is designed for placement in a passage between the trachea and the esophagus for voice restoration following laryngectomy. The one-way valve of the Duckbill protects the airway during swallowing and opens under positive pressure so that air crosses into the esophagus to produce voice.
