Zusammenfassung:	A check valve for high flow medical gas applications is disclosed. The check valve includes a valve body that defines a flow channel through the valve body from an inlet to an outlet. A movable plunger is in the flow channel of the valve body, with the plunger being constrained in the flow channel between the inlet and the outlet. The plunger comprises a finned frustoconical inlet end a finned frustoconical tip at its outlet which act as flow directing elements which reduce inlet and outlet turbulence at higher medical gas pressures by reducing the gas flow turbulence within the flow channel.
