Abstract
A laryngoscope device for use in the performance of direct laryngoscopy, the device including a laryngoscope blade portion connectable to a laryngoscope handle through a connector, the laryngoscope blade comprising an ultraviolet light, a white light and an imaging or viewing device at the same distance relative to the distal end of the laryngoscope blade.
Claims25
A device for use in the performance of an endotracheal intubation, comprising:
- a laryngoscope blade having a proximate portion and a distal portion with a distal end, the laryngoscope blade connectable to a laryngoscope handle through a connection section;
- at least two different light sources carried by the laryngoscope blade and in equal distance from the distal end of the laryngoscope blade, the two light sources comprising an ultraviolet light source and a white light source that, in combination, allows for the illumination of ultraviolet light being absorbed and self promotes back light from phosphorous reactions;
- and
- an imaging device carried by the laryngoscope blade a distance from the distal end that is substantially equal to the distance between the distal end and the ultraviolet light source and the white light source,
- wherein the ultraviolet light source and the white light source include ends that light is emitted from, and the light sources are stacked white light and ultraviolet light LEDs combined into a single integrated unit including epoxy holding compartments that contain the white light source and the ultraviolet light source, the epoxy holding compartments integrated together into a single unit and including epoxy extending beyond the ends of the ultraviolet light source and the white light source so that the epoxy holding compartments form an external dual-domed configuration.

A laryngoscope for use in viewing the vocal chords and trachea of a patient while performing endotracheal intubation or attempting to remove a foreign body obstructing the trachea, comprising:
- a laryngoscope handle adapted for gripping by a user;
- a laryngoscope blade having a proximal portion configured for connection to the laryngoscope handle and a distal portion configured for insertion into a patient's mouth into an operative position, the distal portion having a distal end facing an opening of the trachea in the operative position;
- at least two different light sources carried by the laryngoscope blade and both located at a first distance from the distal end of the laryngoscope blade, the at least two light sources comprising an ultraviolet (UV) light source and a white light source, the light sources being stacked white light and ultraviolet light LEDs and together configured to provide illumination in a portion of the trachea extending from the trachea opening, and the UV light source configured to prompt the visible effects of fluorescence and phosphoresence in illuminated tissues in the trachea and to produce phosphorescence from absorption of UV light in a foreign body having a phosphor content located in the illuminated portion of the trachea;
- and
- an imaging device carried by the laryngoscope blade and configured to produce an image of the illuminated portion of the trachea and any foreign object obstructing the illuminated portion,
- wherein the light sources are combined into a single integrated unit including epoxy holding compartments that contain the white light source and the ultraviolet light source, the epoxy holding compartments integrated together into a single unit and each epoxy holding compartment including a domed configuration so that the epoxy holding compartments form an external dual-domed configuration.
