Abstract

PURPOSE: To facilitate an easy handling of an expiration sampling device, by purging the gas within a Douglas bag with the bag attached to the pressure room and then collecting the expired gas of the subject into the bag to send it directly to the analyzing device.
CONSTITUTION: The mouthpiece 1, a flow rate meter to measure the flow rate of the expired gas plus the Douglas bags 3W5 for collection of the expired gas are provided in the pressure room O. The double-position electromagnetic switching valves 6W14 are opened and closed in the conduction and nonconduction of the solenoid each. The valve 6 is opened only when the expired gas is collected, and either one of the valves 7W9 is opened selectively in accordance with the collection of expired gass into either one of the bags 3W5. The valve 10 is opened when the expired gas sampled into the bags 3W5 is sent to the analyzing device, and the valve 11 is attached to the tube line which is constantly open to the room O to be opened when an analysis is required for the air within the room O.
