  • Patent number: 11602268
    Abstract: In one embodiment, the present invention relates to a laryngoscope. The laryngoscope includes a blade. The blade includes a first end and a second end extending along the longitudinal axis of the blade. The blade further includes a first edge defining a first side of the blade, as well as a second edge defining a second side of the blade, and the first edge and the second edge extend along a longitudinal axis of the blade. The blade further includes a first curvature from the first end to the second end extending upward along a vertical axis, and a second curvature from the first edge to the second edge also extending upward along the vertical axis. The second curvature allows for considerable tongue control without the need for a large flange that typically causes significant risk of damage to a patient's teeth and other sensitive surrounding tissue.
