Airway devices and methods of use thereof

An airway device comprising:

• an elongated blade comprising:
• first and second longitudinal edges and proximal and distal lateral edges, each of the proximal and distal lateral edges connecting the first longitudinal edge to the second longitudinal edge at opposing sides thereof,
• a proximal region proximate to the proximal lateral edge, and a distal region proximate to the distal lateral edge,
• a pair of side components arranged laterally spaced-apart on the elongated blade, wherein each of the side components is arranged to project outwardly from a first face of the elongated blade at the distal region thereof;
• a distal plate region defined by a space separating the pair of side components, dimensioned for a device to pass therethrough towards a distal tip of the blade;
• a ramp joined to the first face of the blade at the distal region thereof, wherein the ramp comprises a first ramp longitudinal side, an opposing second ramp longitudinal side, and proximal and distal ramp lateral sides each connecting the first ramp longitudinal side to the second ramp longitudinal side at opposing sides thereof, the ramp being positioned between the pair of side components;
• a distal conduit extending laterally on the elongated blade, the distal conduit being arranged proximal or distal to proximal lateral sides of the side components along a longitudinal axis of the blade, the distal conduit defining a channel dimensioned to allow passage of the device;
• and
• an epiglottis elevating bar joined to the distal conduit at a proximal lateral edge of the epiglottis elevating bar, the epiglottis elevating bar being arranged to extend distally from the distal conduit, and above the ramp.

• one or more second blades;
• and
• a rail joined on the elongated blade, the rail defining a channel dimensioned to receive the one or more second blades, wherein the one or more second blades is moveable within the channel along a longitudinal axis of the rail,
• wherein the one or more second blades comprise a roll-down blade, and wherein the roll-down blade comprises an elongated body having first and second longitudinal sides and proximal and distal lateral sides, each the proximal and distal lateral sides connecting the first to the second longitudinal sides at opposite sides thereof,
• and wherein the elongated blade defines an elongated slot between the first and second longitudinal edges of the elongated blade, the elongated slot being dimensioned for the roll-down blade to pass therethrough.
