Abstract

A mask is provided for the inhalation of medication, such as asthmatic medication. The mask is molded of a resilient plastic or rubber material and has a central through opening and includes an open front portion adapted to receive an aerosolization chamber which receives medication from a metered dose inhaler. A sidewall expands outwardly from the open front portion and is adapted to fit sealingly on a face covering the mouth and nose. The sidewall is provided with an extension to accommodate the nose. A one-way exhalation valve is provided in the mask, preferably at the far end of the nose accommodating extension for conveying exhaled air to the outside, and preventing entrance of outside air therethrough into said mask.
