Abstract
An inhalation device for use in respiratory therapy is described. The inhalation device or incentive breathing exerciser includes an inner bellows whose deflection allows accurate measurement of the initial volume of air inhaled by a patient and an outer bellows for measuring larger volumes of air after a valve in the inner bellows opens. The exerciser permits measurement of the true volume of air inhaled by a patient and is equipped with a simple timer for measuring the interval of time an inhaled breath is held. Removable handles and the flexible bellows permit collapse of the device for storage and shipment as a compact unit.
