1. A facemask for use with a respiratory therapy device or oxygen delivery system comprising:
- a mask portion adapted to conform to a portion of a face of a user to cover a nose and mouth of a user;
said mask portion having an opening therein for receiving therethrough a connector for coupling said facemask to a respiratory therapy device or oxygen delivery system;
a connector adapted to be received and retained in said opening in said facemask for coupling said facemask to a respiratory therapy device or oxygen delivery system;
said connector having a central portion extending outwardly therefrom for engaging and coupling thereto a respiratory therapy device or oxygen delivery system;
said central portion of said connector having carried therein a one-way inspiratory air valve through which inspiratory air may be drawn into said mask portion from a respiratory therapy device or oxygen delivery system when coupled thereto;
said connector having at least one opening formed therein through which expiratory air may be passed from said facemask without passing into a respiratory therapy device or oxygen delivery system when coupled thereto; and
said mask portion having at least one one-way valve formed thereby through which expiratory air may be passed to said expiratory air opening formed in said connector.

Abstract
A non-rebreathing facemask removably securable onto a connector which is attachable directly to an aerosol medication system, illustrated for example as an aerosol cloud enchancer for use in respiratory therapy, or an oxygen delivery system. The connector to which the facemask is secured functions in cooperation with the facemask to provide a valving system for discharging a patient'"'"'s expiratory air outside of the medication or oxygen delivery system, while permitting the patient to smoothly inhale inspiratory air.

7. A connector adapted to be received and retained in an opening in a facemask for coupling the facemask to a respiratory therapy device or oxygen delivery system comprising:
-
a facemask connector having a central portion extending outwardly therefrom for engagement with and coupling to a respiratory therapy device or oxygen delivery system, and a facemask connecting portion for engagement with and coupling to a facemask; said central portion of said connector including a one-way inspiratory air valve through which inspiratory air may be drawn through said connector into a facemask from a respiratory therapy device or oxygen delivery system when coupled thereto; and said facemask connecting portion forming a portion of at least one expiratory air valve through which expiratory air may be passed when said connector is coupled to the facemask without passing the expiratory air into the respiratory therapy device or oxygen delivery system when coupled thereto. - View Dependent Claims (8, 9)
