Lung exercising device and method

Abstract

A device and method for increasing inhalation strength and capacity of the lungs. The device includes an air inlet and air outlet which are interconnected by a conduit. A valve in the conduit is opened by the pressure differential created when the user inhales through a mouthpiece. The valve is biased to a normally closed position. The biasing force is adjustable so that the force required to open the valve during inhalation can be varied to increase the strength of the users' lungs. A timer is provided for monitoring the length of time of successive inhalations. The method includes the steps of inhaling through a mouthpiece and flexible conduit, creating a vacuum in said conduit of sufficient force to open a variable resistance valve, and breathing in atmospheric air to fill the lungs. The amount of air inhaled is monitored.
