Laryngoscope
A laryngoscope comprises a handle and an elongated blade detachably fixed to the handle. The blade includes a stationary portion having a longitudinal axis, a distal end of the stationary portion of the blade having a surface angled and upwardly and outwardly. A movable portion of the blade has a surface for engaging the tongue of the patient. The movable portion is mounted to the stationary portion of the blade for rotation about an axis substantially along the longitudinal axis of the blade. An operating member is manipulated by a user for rotating the movable portion of the blade. Laryngoscopy of a patient includes at least a rotating motion of the movable portion of the blade. In one embodiment, the laryngoscope comprises a tubular handle and an arcuate tubular blade integral with the handle.
1. A device for inserting into a mouth of a patient having a tongue for intubating the patient, the intubation device comprising:
a tubular handle;
an arcuate tubular blade integral with the handle, the blade including
a stationary portion having a longitudinal axis and an upper surface, and
a movable portion having an upper surface for engaging the tongue of the patient, the movable portion mounted to the stationary portion of the blade for rotation about an axis substantially parallel to the longitudinal axis of the stationary portion of the blade from a first position of the movable portion where the upper surface of the movable portion is continuous with the upper surface of the stationary portion; and
an operating member configured to be manipulated by a user for rotating the movable portion of the blade to a second position relative to the stationary portion of the blade such that the upper tongue engaging surface of the movable portion of the blade moves upwardly from the handle,
wherein intubation of the patient by manipulation of the handle includes at least the rotating motion of the movable portion of the blade for moving the tongue.
2. The laryngoscope as recited in claim 1 , wherein the operating member comprises an elongate rod integrally formed with the movable portion of the blade.
3. The laryngoscope as recited in claim 1 , wherein the tubular handle comprises means for directing a camera toward a distal end of blade.
