Inspiratory mask device for avoiding occlusion by using contractility during patient breathing

The invention relates to the technical field of suction hoods, and discloses an inspiratory mask device for avoiding occlusion by using contractility during patient breathing. The device comprises anadsorption cover, a connecting belt is fixedly connected to the side wall of the adsorption cover, a movable belt penetrates through the side wall of the connecting belt, a folding pipe is movably connected to the side wall of the adsorption cover, a placing groove penetrates through the side wall of the adsorption cover, a movable plate penetrates through the side wall of the placing groove, anda movable pipe penetrates through the axis of the top side of the adsorption cover. When the placing groove is not subjected to contractility when gas is sucked in any more, the movable plate reboundsto the original position, the movable plate straightens the side wall of the adsorption cover, and blockage of the respiratory tract caused by the gas exhaled from the patient is avoided. Due to thefact that the interior of th
