Abstract
A spirometer for encouraging inhalation exercises and particularly for indicating the volume of air that is inhaled by the user. The spirometer comprises a two-part generally cylindrical housing having a bellows assembly positioned therein. A breathing tube is connected to a port in the housing that communicates with the interior of the bellows. By inhaling through the breathing tube the user causes the bellows to contract and a pointer on the bellows coacts with a scale on the housing to indicate the amount of air that has been inhaled. Each of the housing parts is formed with a plurality of spaced apart discrete wall sections and the sections of the two parts interfit with one another to reduce the size of the spirometer for shipping.
