ABSTRACT:
A respiratory exerciser which includes a hollow tubular body having at least two openings at one end and an opening at the other end. A piston is reciprocally slidable in the tubular body. A mouthpiece assembly is removably connectable to one opening at the one end of the body so that when the patient inhales and exhales the piston will reciprocate accordingly. Adjustment structure is on the one end to regulate the size of at least another of the openings therein to control the size of the access opening to atmosphere at the one end as the patient breathes through the mouthpiece assembly. An indicator is associated with the adjustment structure to designate the relative size of the access opening to atmosphere at the one end. The structure permits use of the device as an exerciser for inhaling or exhaling and provides adjustment for accommodating changes in strength required by the patient in the exhaling and inhaling exercises.
