PORTABLE SPIROMETER CAPABLE OF MEASURING LUNG CAPACITY

摘要

PURPOSE: A portable spirometer is provided to reduce power consumption by analyzing a breath signal with software of a PC. ;CONSTITUTION: The breath flow of a subject is inputted to a small breath tube(110) for measuring one way air flow. A breath signal processor generates a breath signal from the breath flow and generates an analysis target signal by amplifying a signal level and removing a noise included in the breath signal. A breath signal analyzing unit(130) produces a diagnosis parameter by analyzing the analysis target signal. A display unit(140) displays the breath signal analysis result.;COPYRIGHT KIPO 2011
