A dual blade laryngoscope having a folding handle and a manually installable lighting cartridge. The laryngoscope includes two spaced apart parallel blades and a wall spanning both. A slot is formed at one end of the parallel blades for receiving the lighting cartridge. A translucent or transparent lens covers a visualization channel defined between the parallel blades. The folding handle includes an axle to enable pivoting between a deployed position and a stowed position, and a projection which activates the lighting cartridge. The lighting cartridge and the transparent lens are removable. Each of the parallel blades has a curved portion at forward ends thereof to facilitate managing soft tissue and directional control of an endotracheal tube during insertion in a patient. A tooth guard pad of compliant rubber-like material may be permanently affixed to the underside of lower blade.
