ABSTRACT:
A volume-type incentive spirometer for respiration therapy is disclosed. The spirometer includes a central tubular support on which is mounted a collapsible bellows-like chamber. Fluid communication is provided between the support and the interior of the chamber and, further, between the support and a patient. The collapsible chamber includes a top plate by which the chamber is mounted on the support, a bottom plate for biasing the collapsible chamber to an open position, and an intervening flexible, readily collapsible side wall joining the top and bottom plates. The collapsible chamber or the collapsible chamber and support member may be disposable. The spirometer provides respiratory exercise so that alveolar inflation is assured.
