ABSTRACT:
An exhalation valve assembly for use in a volume ventilator circuit is disclosed. The valve assembly comprises a valve body defining a chamber with a gas inlet conduit and a gas outlet conduit, both in flow communication with the chamber. A diaphragm extends across the chamber and selectively closes off the gas inlet conduit. Upwardly extending strut members are disposed on an inside surface of the valve body and are used to position a removable ring member adjacent the diaphragm. The ring member is configured so as to support a portion of the diaphragm over the chamber.
