Abstract
Single use laryngoscope handle for use in an ISO 7376 compatible dual component laryngoscope assembly with an illumination arrangement. The laryngoscope handle includes a plastic hand grip, a plastic end cap, and at least one plastic frangible member for engaging a hand grip and an end cap in a pre-actuated position of an end cap which is broken on application of a relatively minor manual detachment force to the end cap, thereby precluding subsequent use of the laryngoscope handle.
Claims12
A single use laryngoscope handle for use in a dual component laryngoscope assembly including (a) 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 (b) an illumination arrangement including an electrically 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 electrically operating the electrically operated illumination source in the operative intubation position, and
- c) a plastic end cap mounted on said trailing hand grip end in a pre-actuated position, said plastic end cap having an upright 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,
- said plastic end cap including a transverse end plate and an upright end wall, the transverse end plate having at least one axially extending plastic frangible member extending from the transverse end plate between the upright end wall and the upright support member, the frangible member facing radially outward away from said upright 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 in the pre-actuated position, 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 single use laryngoscope handle having a longitudinal handle axis and comprising:
- a) an elongated tubular 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 a power source assembly compartment for electrically operating an electrically operated illumination source in an operative intubation position, and
- c) an end cap mounted on said trailing hand grip end in a pre-actuated position, said end cap having an uptight 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,
- said end cap including an upright end wall and having at least one axially extending frangible member disposed between the upright end wall and the upright support member, the frangible member facing radially outward away from said upright support member for engaging said trailing hand grip end, the frangible member abutting against the upright end wall in the pre-actuated position, such that a manual actuation of said end cap from said pre-actuated position breaks said at least one 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, and
- said end cap including a cap ring disposed between said upright support member and said at least one frangible member and configured to ensure snapping of said at least one frangible member on said manual actuation of said end cap from said pre-actuated position.
A single use laryngoscope handle having a longitudinal handle axis and comprising:
- an elongated tubular 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;
- a power source assembly for storage in a power source assembly compartment for electrically operating an electrically operated illumination source in an operative intubation position;
- and
- an end cap mounted on said trailing hand grip end in a pre-actuated position, said end cap having an upright 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, said end cap including an upright end wall and having at least one axially extending frangible member disposed between the upright end wall and the upright support member, the frangible member facing radially outward away from said upright support member for engaging said trailing hand grip end, the frangible member abutting against the upright end wall in the pre-actuated position, such that a manual actuation of said end cap from said pre-actuated position breaks said at least one 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.
