Abstract: 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.

Abstract: A novel positive pressure and volume measurement respiratory device is disclosed which provides positive pressure respiratory therapy to the user. Simultaneously the user's inspiration volume can be measured by merely observing the amount of liquid displaced from one container to another. The respiratory therapy device is comprised of two containers connected by flexible tubing which are raised and lowered relative to one another by appropriate linkage connected to a motor either cyclically or intermittently dependent upon the needs of the user. A user tube which communicates with the interior of one container acts as the conduit to the mouth of the user for expelled air when positive pressure is developed within the container.

Abstract: A novel combination inhalation and exhalation respiratory therapy device is shown which allows measurement of the respiratory capacity of the user. Additionally, it is so constructed that the user or one supervising the user may control the rate of inspiration or exhalation while simultaneously measuring the total volume of air inhaled or exhaled. The respiratory therapy device, to be used with a liquid such as water, is comprised of two containers inter-connected by a conduit tube through openings in either the top wall portion or side wall portion of each respective container. Additionally, an opening is provided in the top wall portion of the first container to communicate atmospheric pressure to the surface of the liquid contained therein. A tube is fixedly mounted through the top wall portion of the second container having a user end adapted to be placed in the mouth of the patient.

Abstract: An intermittent pressure pneumatic stocking system for creating pressure changes on selected parts of the body of the user or patient. The pneumatic stocking is filled with air or other suitable gas to a selected low pressure and through slight movements of a bedridden patient intermittent pressure changes to selected external areas of the body are achieved. Movements of the patient cause pressure and volume changes in a first pneumatic sac placed under the patient or wrapped around the torso of the patient. These changes in pressure and volume cause gas displacement through pneumatic tubing to at least one second pneumatic sac located on one of the patient's extremities. The second pneumatic sac is so arranged to surround the particular region such as the calf of a leg. Each of the pneumatic sacs may be divided into a plurality of compartments.

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.
