Bulb Laryngoscope

A Miller Bulb Laryngoscope is a rigid laryngoscope with straight Miller blade (sizes 0-4, 70-160 mm) featuring a distal incandescent (xenon, krypton, halogen) or LED bulb at the blade tip for direct illumination during tracheal intubation. The straight blade design allows direct elevation of the epiglottis rather than the indirect vallecula technique, making it the preferred choice for pediatric and neonatal intubation, patients with floppy or prominent epiglottis, and anterior airways requiring direct epiglottic control. Features stainless steel reusable blades (or disposable plastic), ergonomic handles with knurled grip, ISO standard hook-on fittings, and autoclavable options. Light output 500-3,000 Lux depending on bulb type and battery condition. Primary clinical applications include direct epiglottis elevation for tracheal intubation (especially pediatric and neonatal), patients with prominent or floppy epiglottis, anterior airway management, teaching and training (straight blade technique), neonatal resuscitation, and use in resource-limited settings. Class II medical device requiring FDA clearance. Critical safety considerations include pre-use light check (brightness, bulb security), appropriate blade size selection (especially critical in pediatrics), proper lifting technique (direct epiglottic lift, not levering on teeth), pediatric fragility awareness, bulb obstruction risk from secretions, battery verification, and backup device availability.
