A two-way on-off electromagnetic valve is provided in the expiration transmission passage, and an O.sub.2 sensor is provided between the electromagnetic valve and the sample outlet as a standard gas sensor. The syringe has a capacity capable of collecting several breaths, and a sucking operation is driven at a speed for collecting several breaths in single suction.
