Multifunctional intubating guide stylet and laryngoscope
First Claim
Patent Images
1. An intubating guide stylet and laryngoscope, comprising:
- a rigid curved body, having a distal end for fitting into human oral and pharyngeal passageways, said body containing therein both a means for viewing and a means for illuminating a field adjacent said distal end of said body, and a laryngoscope blade affixed to said distal end of said body;
a hollow tubular stylet having a distal end and a proximal end, said stylet being affixed to said body by a connection remote from said stylet distal end, said hollow stylet having an inner diameter adapted to permit a flexible guide member having a distal end to be passed therethrough, and an outer diameter adapted to permit an endotracheal tube to be mounted on the exterior of said stylet;
said stylet distal end being located adjacent said distal end of said body such that, upon passage of a flexible guide member through said stylet, the flexible guide member will be manipulated to position the guide member at a desired position in a patient'"'"'s anatomy with direct vision by said illuminating and viewing means of said body, such that an endotracheal tube, when mounted to said stylet, may be advanced along the stylet onto the guide member to be positioned in the patient at the desired position in the patient'"'"'s anatomy.

Abstract
A multifunctional intubating stylet and laryngoscope, and a method of intubating a patient, comprise a laryngoscope body, and a hollow tubular intubating stylet affixed to and extending generally parallel to the laryngoscope body. An endotracheal tube is mounted on the exterior of the stylet. A guide member is passed through the interior of the stylet and advanced through the patient'"'"'s vocal cords into the trachea. The endotracheal tube is then advanced along the guide member until it is established in a desired location in the patient'"'"'s trachea to permit ventilation of the patient.

10. A medical optical device comprising:
-
a rigid body having a distal end and a fiber optic optical channel for viewing a target area, and a fiber optic illuminating channel for providing light to the target area; a hollow tubular stylet having a distal end and a proximal end, said stylet being affixed to said body by a connection remote from said stylet distal end, said hollow stylet having an inner diameter sized to permit a flexible member to be passed therethrough, and an outer diameter sized to permit a flexible tube to be mounted on the exterior of said stylet;
said stylet distal end being located adjacent said distal end of said body such that, upon passage of a flexible guide member through said stylet, the flexible guide member will be manipulated to position the guide member at a desired position in a patient'"'"'s anatomy with direct vision by said illuminating and viewing means of said body, such that a flexible tube, when mounted to said stylet, may be advanced along the stylet onto the guide member to be positioned in the patient at the desired position in the patient'"'"'s anatomy. - View Dependent Claims (11, 12, 13)
