Calibration and performance verification device for diagnostic spirometer

摘要

3-liter calibration The performance of the diagnostic spirometer is achieved by placing two syringes side-by-side in parallel and connecting the servomotor, servo driver, uniaxial robot, and controller that drives the two syringes to one panel to automatically drive two syringes And an apparatus for calibrating and verifying performance of a diagnostic spirometer capable of automatically setting and inputting various velocities and correcting an airflow of an accurate volume and providing the same to a diagnostic spirometer. Through the above-described apparatus, the user can repeatedly provide any desired airflow and volume to the spirometer by automatically setting the airflow value within the range of 0 to 15 [LPS] by using the servo motor, The direct performance comparison of the diagnostic spirometer product can be made possible, and the manual correction work can be performed accurately by setting various speeds.
