ることを特徴とする医療用ガスミキサー。 Two flow rate adjustment valves consisting of an airtight plunger, an integrated needle, and an orifice are arranged at both ends of a lever that moves around the rotation axis, and one end of this lever is moved by rotation of the mixture ratio adjustment knob, and this flow rate adjustment valve is When one of the needles opens, the other closes, and the needle has a cross-sectional shape that is quadratic in order to change the gas flow rate almost linearly with respect to the amount of movement and to keep the mixed gas flow rate constant. A medical gas mixer characterized in that the plunger is formed in a curved shape, and further has a structure in which the needle abuts the orifice via an internal spring and is further compressed to close the plug.
