ABSTRACT:
A laryngoscope blade having a self contained base housing integral with a bottom surface of a laryngoscope spatula. The blade is easily attachable and detachable from a standard laryngoscope handle containing a battery pack and axial pin for engagement with the blade's latch. The bulb is easily threaded into the base housing through a central channel and is removable for replacement by turning the bulb's ribbed base protruding from below the base housing. A bundle of light conducting fibers enclosed within a metal sheath transmit light from the housing to a position near the end of the laryngoscope spatual.
