Claims

[Scope of utility model registration request]

(1) In a gas sampling device comprising an intake/exhaust port to which a detection tube is connected, and an intake/exhaust chamber made of a flexible elastic material whose internal volume is variable by expansion and contraction, and with which the intake/exhaust port communicates, the intake/exhaust chamber A gas sampling device comprising: a counter that counts and displays the number of times a gas sample is drawn from the detection tube by expanding and contracting the detector tube.

(2) a pair of pressing members provided at both ends of the intake and exhaust chamber;
A first push pin fixed to one of the pressing members, a second push pin that is movably elastically mounted on the other of the pressing members and that allows the first push pin to move toward and away from the first push pin, and is operated by the second push pin. 2. A gas sampling device according to claim 1, comprising a mechanical counter having a counter lever.

(3) The gas sampling device according to claim 1, wherein the counter is an electric counter with a built-in battery.
