<P>PROBLEM TO BE SOLVED: To provide a simple breathing function test device performing a breathing function test in a state without the need of breathing effort, such as a quiet breathing state. <P>SOLUTION: When a subject exhales, exhaled air passes through a one-way valve 81, passes through a hole of a drag body 71, passes through an exhaled air route 61, and reaches a flow sensor 5. When the subject inhales, inhaled air passes through an inhaled air route 62 from the flow sensor 5, passes through a one-way valve 82, and reaches a mouthpiece 50. The subject is made to perform quiet breathing, a flow volume curve and intraoral pressure for the time without a load when the drag body 71 is not connected are acquired, and a flow volume curve and intraoral pressure for the time with a load when the drag body 71 is connected are acquired. Since COPD (Chronic Obstructive Pulmonary Disease) patient is hardly affected by load drag, comparing both is useful for COPD diagnosing. <P>COPYRIGHT: (C)2013,JPO&INPIT |
