ABSTRACT:
Methods for improving speech and other functions of a tracheostomized patient are disclosed, together with an apparatus for carrying out the methods. The methods involve providing the patient with a tracheostomy valve that prevents airflow at all times except when the patient inhales. A way for doing so by positively biasing a flexible diaphragm against a valve seat is disclosed, together with a rivet structure for effecting such bias.
