ABSTRACT:
A speech prosthesis device which is inserted into a surgically created opening communicating the trachea and esophagus of a laryngectomized patient includes a one-way valve assembly that permits air to be channeled air from the patient's trachea into the patient's esophagus while preventing flow of esophageal material into the trachea. The present invention provides an improvement in such prosthesis devices by providing that the membrane-like, tabbed flap or disc is seated at an angle which is oblique in reference to the longitudinal axis of the tubular housing of the device be, preferably, oval shaped, and that the tabbed flap or disk be superiorily hinged to the tubular housing. The predetermined and uniform resistance to airflow offered by the one-way valve assembly of the present invention is substantially less than the resistance offered by a normal human larynx.
