US 12,599,737 B1 · Laryngoscope blade with a channel

Abstract

The present disclosure relates to a laryngoscope blade modification for endotracheal intubation. The disclosure provides a flexible channel attached to the laryngoscope blade or a rigid channel that opens via a spring system. The channel further incudes a slit along the entire portion of the channel, enabling a guidewire to be loaded into the channel and advanced to a patient's vocal cords and trachea before being dislodged or removed in a quick, efficient manner. An endotracheal tube is then slided over the guidewire into the vocal cords and trachea. Once endotracheal tube is inserted, guidewire is removed and intubation initiated. The present disclosure enables a faster insertion of a guidewire into the vocal cords over conventional methods without wasting precious seconds. By using a guidewire with a soft tip, the incidence of vocal cord injury decreases substantially and intubation performed successfully in a quick manner.

Dependent claims

An apparatus for facilitating the insertion of an endotracheal tube during endotracheal intubation, comprising:

a laryngoscope blade having a length and a width;
and
a guidewire channel having a length and a width sized to slidably receive a guidewire with a slit having opposing edges along the length of the guidewire channel, wherein the opposing edges of the slit contact each other to create a closed position, attached to the laryngoscope blade wherein the guidewire channel directs the guidewire the length of the laryngoscope blade and the slit prevents ingress of liquid into the guidewire channel and allows the guidewire to be removed from the guidwire channel when the endotracheal tube is advanced onto the guidewire outside of the guidewire channel and wherein the slit returns to the closed position and the prevention of ingress of liquid is maintained after the guidewire has been removed;
wherein the guidewire channel has an inner cross-sectional dimension sufficient to permit passage of the guidewire and insufficient to permit passage of an endotracheal tube.

A method of endotracheal intubation, the method comprising:

attaching a guidewire channel to a direct laryngoscope blade;
loading an endotracheal tube on a guidewire;
loading the guidewire into the guidewire channel of the direct laryngoscope;
inserting the direct laryngoscope in the mouth of the patient;
advancing the direct laryngoscope into the oropharynx of the patient;
finding, using direct inspection by an operator, the vocal cords of the patient;
advancing the guidewire towards the vocal cords of the patient;
advancing the guidewire into the trachea of the patient;
dislodging the guidewire partially from the guidewire channel of the direct laryngoscope through a slit in the guidewire channel;
dislodging the guidewire partially from the guidewire channel of the direct laryngoscope through a slit in the guidewire channel while maintaining the slit in a closed position relative to the guidewire or fiber-optic scope to prevent liquid ingress into the guidewire channel;
advancing the endotracheal tube over the guidewire to completely dislodge the guidewire from the guidewire channel wherein the slit returns to a closed position after dislodgment;
advancing the endotracheal tube outside of the guidewire channel into the oropharynx of the patient;
advancing the endotracheal tube into the vocal cords of the patient;
advancing the endotracheal tube into the trachea of the patient;
confirming, the placement of the endotracheal tube, using direct inspection by the operator;
stopping the advancement of the endotracheal tube, once an endotracheal tube cuff is beyond the vocal cords of the patient;
removing the guidewire from the endotracheal tube;
connecting the endotracheal tube to an anesthesia machine circuit;
removing the laryngoscope from the mouth of the patient;
and
securing the endotracheal tube in place to the patient;
wherein the guidewire channel has an inner cross-sectional dimension sufficient to permit passage of the guidewire and insufficient to permit passage of an endotracheal tube.
