Abstract

A breathing exerciser, comprising: first and second tubes; a lower cap member having bores for receiving one end of each of the tubes, the lower cap member having a passageway communicating between the first tube and a lower inlet/outlet opening; an upper cap member having bores for receiving the other ends of the tubes, and having a passageway communicating between both the tubes and an upper inlet/outlet opening; a floor member closing the lower end of the second tube; a floatable indicating member disposed in the second tube, the indicating member being upwardly movable during fluid flow into the upper inlet/outlet opening, through the first tube and out of the lower inlet/outlet opening, the amount of upward movement depending upon the rate of fluid flow; a valve assembly for adjusting the effective size of at least one of the inlet/outlet openings, for controlling the fluid flow rate required to move the indicating member over an effective range; and, openings in the second tube for calibrating the effective range, whereby the volume of air inhaled through the exerciser can be monitored and controlled.
