Variable flow incentive spirometer |
摘要 |
An incentive spirometer for breathing control exercising of post-operative patients having flow varying capability. A patient breathing tube connects through a chamber in a base and through suction tubes to the upper end of a gauge tube in which a calibrated ball having a diameter substantially the same as the gauge tube is movable. Vent means in the gauge tube below the ball allow atmospheric air to act on the lower surface of the ball so that inhalation by the patient will cause the ball to rise in the gauge tube.
