An improved positive reinforcement respiratory inhalation device of simple construction is provided for respiratory therapy while simultaneously providing to the user controlled ingestion of liquid. The device is used primarily for post-surgical patients when respiratory therapy is most important and restricted liquid intake is usually required. The respiratory inhalation device includes a container for holding liquid and a tube assembly having a first tube slideably coupled to and concentric with the second tube affixed to the container. In one version the tube assembly is affixed to the bottom wall portion of the container. One end of the tube assembly projects to a point adjacent the bottom wall of the container and the second end is adapted for insertion into the mouth of a user. One or the other or both of the first and second tubes are provided with openings in side wall portions thereof whose aperture is adjustable by the sliding movement of one tube relative to the other. The adjustment is made by a longitudinal movement of one tube relative to the second or in a modified embodiment the adjustment in aperture of the openings is made by a rotational movement of one tube about the longitudinal axis of the tube assembly.
