摘要

The present invention relates to a system (1) for obtaining measuring characteristic correction factors for a respiratory flow measuring device (50) using a differential pressure difference. The system (1) has a 3 L syringe (10), a detecting unit (20), an A/D converter (30) and a computer (40). The 3 L syringe (10) is connected to a respiratory tube of the respiratory flow measuring device (50) through a duct line. The detecting unit (20) detects volume variation within the syringe (10) and outputs the detected result as a voltage signal. The A/D converter (30) converts a volume variation signal, detected as the voltage signal by the detecting unit (20), and a differential pressure variation signal, detected as a voltage signal by a differential pressure sensor (54) through a signal extracting circuit (56) into digital signals. The computer (40) calculates measuring characteristic correction factors using the digital signals.
