Abstract

A laryngoscope constructed of materials including metal components having very low magnetic susceptibilities is described. The battery powering the laryngoscope lamp is a lithium battery also constructed of materials having low magnetic susceptibilities. The battery further includes a unique terminal configuration that prevents the inadvertent use of other batteries, including non-magnetic batteries, in the laryngoscope. A unique lamp retaining mechanism provides for quick and easy replacement of the lamp.
