Abstract: An incentive spirometer is disclosed having a helical tube, wherein the helical tube includes a first inlet, second outlet, third outlet, and fourth outlet. The spirometer further includes a chamber, wherein the chamber is in fluid communication with the first inlet, second outlet, third outlet, and fourth outlet of the helical tube; and an object disposed within the spirometer, wherein the object is adapted to move through the first inlet of the helical tube and through either the second outlet, third outlet, or fourth outlet. In addition, the spirometer further includes an inhalation draw tube in fluid communication with the chamber and helical tube.

Abstract: An incentive spirometer is provided that allows a user to achieve Sustained Maximal Inspiration (SMI) through the use of helical tubes. Specifically, the incentive spirometer includes three chambers, wherein each chamber includes a ball traveling upwards through three helical tubes in sequential order and subsequently dropping down through a basket. Here, each of the helical tubes and corresponding baskets generally represent various levels of lung capacity achieved with repetitive use and operation of the incentive spirometer.
