A single use laryngoscope handle for use in a dual component laryngoscope assembly including (i) a laryngoscope blade having a spatula and intended for dual snap fit engagement on the laryngoscope handle to dispose the spatula into an operative intubation position generally transverse to the laryngoscope handle, the spatula having a distal spatula end remote from the laryngoscope handle in the operative intubation position, and (ii) an illumination arrangement including an electrical operated illumination source for selectively providing illumination at the distal spatula end in the operative intubation position, the single use laryngoscope handle having a longitudinal handle axis and comprising: a) an elongated tubular plastic hand grip having a leading hand grip end, a trailing hand grip end and a power source assembly compartment between said leading hand grip end and said trailing hand grip end; b) a power source assembly for storage in said power source assembly compartment for electrical operating the electrical operated illumination source in the operative intubation position, and c) a plastic end cap for mounting on said trailing hand grip end in a pre-actuated position, said plastic end cap having an upright and axially directed central support member for supporting said power source assembly at said leading hand grip end in said pre-actuated position in an upright handle orientation of the laryngoscope handle with said leading hand grip end above said trailing hand grip end characterized by said plastic end cap including a transverse end plate and an upright end wall, the transverse end plate having at least one axial directed plastic frangible member facing radial outward away from said support member for engaging a respective throughgoing aperture formed in a lowermost end of said trailing hand grip end, such that the frangible member protrudes into the throughgoing aperture to abut against the upright end wall, and such that a manual actuation of said end cap from said pre-actuated position breaks said at least one plastic frangible member and detaches said end cap from said trailing hand grip end whereupon said power source assembly readily slides downwardly and outwardly from said trailing hand grip end in said upright handle orientation under gravitational force thereby preventing re-use of said single use laryngoscope handle. a) an elongated tubular plastic hand grip having a leading hand grip end, a trailing hand grip end and a power source assembly compartment between said leading hand grip end and said trailing hand grip end; b) a power source assembly for storage in said power source assembly compartment for electrical operating the electrical operated illumination source in the operative intubation position, and c) a plastic end cap for mounting on said trailing hand grip end in a pre-actuated position, said plastic end cap having an upright and axially directed central support member for supporting said power source assembly at said leading hand grip end in said pre-actuated position in an upright handle orientation of the laryngoscope handle with said leading hand grip end above said trailing hand grip end characterized by said plastic end cap including a transverse end plate and an upright end wall, the transverse end plate having at least one axial directed plastic frangible member facing radial outward away from said support member for engaging a respective throughgoing aperture formed in a lowermost end of said trailing hand grip end, such that the frangible member protrudes into the throughgoing aperture to abut against the upright end wall, and such that a manual actuation of said end cap from said pre-actuated position breaks said at least one plastic frangible member and detaches said end cap from said trailing hand grip end whereupon said power source assembly readily slides downwardly and outwardly from said trailing hand grip end in said upright handle orientation under gravitational force thereby preventing re-use of said single use laryngoscope handle.
