Spirometer with calibrated air tube, calibration data printed on tube |
摘要 |
The present calibrated air tube, includes a resistive element (22) which is located in the hollow space of the tubular portion (12). This resistive element (22) is adapted for providing a linear resistance versus pressure response, and is sized and adapted to cause a pressure difference or differential as air flows in the hollow space across this element. The preferred calibrated air tube has a pressure response, is useful in a spirometer, and includes a tubular member. Calibration information is associated with the air tube to a model pressure response of a model air tube having substantially the same dimensions and configurations as the air tube. |
