Exhalation valve assembly |
摘要 |
An exhalation valve assembly for use in a volume ventilator circuit is disclosed that 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. A concentric ring support structure is disposed concentrically about the gas inlet conduit and is configured so as to support a portion of the diaphragm over the chamber.
