ABSTRACT:
A positive reinforcement respiratory inhalation device is provided for respiratory therapy used primarily for postsurgical patients. The device also provides controlled ingestion of liquid. The respiratory inhalation device includes a container for holding liquid and a first tube projecting through the lid of the container which provides support for a second tube which fits snugly inside the first tube and extends into the container. The second tube has a plurality of openings at various heights in its wall which selectively can be occluded by moving it relative to the first tube. When the container is filled with liquid to a level above a first end of the second tube, the amount of inspiratory effort applied to the second end of the second tube which is required of a patient to withdraw a given amount of liquid from the container can be controlled by adjusting the second tube up or down within the first tube to occlude more or less openings. The more openings occluded, the less effort is required to withdraw a given amount of liquid.
