US 2025/0025029 A1 · NOVEL ILLUMINATING LARYNGOSCOPE AND METHOD OF INTUBATION

Abstract

A laryngoscope and a method of using the laryngoscope in intubating mammals are described. The laryngoscope comprises a pen light grip for holding the laryngoscope like a pen, and an elongate probe attached coaxially via probe grip, wherein the elongate probe (14) is elongate and tapered such that the distal tip of the probe has the smallest cross section profile as compared to any cross section of the probe taken between the tip of the probe and the portion of the probe proximate the probe grip, and where the probe is curved and deflects away from the axis of probe and pen light grip and is substantially made from a material that transmits and or scatters light. The tip angle of deflection is 50 degrees and the deflection measured in mm is 50 mm. The tip 22 is twice as high as it is wide and, at the near tip point, the cross sectional profile is narrower than it is tall.

Dependent claims

A laryngoscope for providing a clear and direct view of the larynx during endotracheal intubation of a mammal, comprising:

a pen grip for holding the laryngoscope like a pen,
an elongated probe;
attached coaxially with the pen grip, wherein:
the elongated probe is elongated and tapered such that a distal tip of the probe has a smallest cross section profile as compared to any cross section of the probe taken between the tip of the probe and a portion of the probe proximate the grip;
the elongated probe is curved and deflects away from the axis of probe and pen grip;
and the elongated probe is substantially made from a material that transmits light;
and
a light source that is directed to the probe, and wherein light incident on the probe is transmitted or scattered in such a way that the probe becomes illuminated and emits light for aid in intubation.

A method for intubating a mammal, comprising:

providing a laryngoscope comprising:
a pen grip for holding the laryngoscope like a pen;
an elongated probe attached coaxially with the pen grip, wherein:
the elongated probe is elongated and tapered such that a distal tip of the probe has a smallest cross section profile as compared to any cross section of the probe taken between the tip of the probe and a portion of the probe proximate the grip;
the elongated probe is curved and deflects away from the axis of probe and pen grip;
and the elongated probe is substantially made from a material that transmits light;
and a light source that is directed to the probe, wherein light incident on the probe is transmitted or scattered in such a way that the probe becomes illuminated and emits light for aid in intubation.
with a first hand, holding the grip of the laryngoscope in a pen grip;
passing the probe of the laryngoscope into the buccal cavity of the mammal and along the roof of the mouth in contact with the hard palate;
pushing the probe caudally, dorsal to the epiglottis, lifting the soft palate with the probe;
visualising the proximal larynx;
applying local anesthetic to the larynx;
pushing the lubricated tip of the probe of the laryngoscope into the small fornix of the vocal folds between the arytenoid cartilages;
raising the tip of the probe dorsally whist pushing it caudally thereby opening the arytenoid cartilages;
using a second hand, passing a lubricated endotracheal tube ventral to (underneath) the laryngoscope and into the proximal larynx;
and
withdrawing the laryngoscope as the endotracheal tube tip is passed gently between the arytenoids.
