Abstract:
Abstract: Objective To satisfy the requirements of the testing and calibration for spirometer by designing and producing an intelligent spirometer testing and calibrating system for generating standard respiratory curves of human and automatically testing and calibrating the spirometer. Methods The system was developed based on piston cylinder driven by a computer control servo motor. Results The tests on the executions and performances of the developed system showed that the system could not only precisely produce 24 standard forced expiratory vital capacity curves and 26 peak expiratory flow waveform curves which were recommended by American Thoracic Society, but also provide the detailed data of the tested spirometer. Conclusion The proposed system is suitable for intellectually testing and analyzing the accuracy and frequency-speed response of the tested and calibrated spirometers. Moreover, the system is also useful for doctors to investigate the pulmonary function indicators which were provided by the spirometry.
