Abstract
The configuration and arrangement of the instrument greatly facilitate safe placement of the instrument and an associated endotracheal tube. The instrument provides a path for guiding movement of the endotracheal tube in a manner that permits the distal end of the tube to move along the instrument directly toward the glottis. The instrument includes a passage into which a telescope is mounted. The arrangement of the guide path and passageway ensure that the advancing end of the tube remains observable as it is advanced to the glottis. Suction is provided to remove fluid etc that would otherwise obscure the view of the tube.
Claims15
An intubation instrument, a portion of which is for insertion into a patient through the patient's mouth, comprising:
- a body having a handle attached thereto;
- an arm attached to the body, the arm having a distal end and being arranged for insertion distal-end first through a patient's mouth and having an anterior surface that faces a patient's lower jaw when the arm is inserted;
- a telescope passage carried by the arm and having an inner end located at the distal end of the arm;
- and
- a guide path formed on the anterior surface of the instrument body and configured for guiding the sliding movement of an endotracheal tube along the anterior surface between the telescope passage and a patient's lower jaw, wherein the guide path includes a loop protruding from the distal end of the arm, through which loop an endotracheal tube is extendable.
An intubation instrument, a portion of which is for insertion into a patient through the patient's mouth, comprising:
- a body having a handle attached thereto;
- an arm attached to the body, the arm having a distal end and being arranged for insertion distal-end first through a patient's mouth and having an anterior surface that faces a patient's lower jaw when the arm is inserted;
- a telescope passage carried by the arm and having an inner end located at the distal end of the arm;
- a guide path formed on the anterior surface of the instrument body and configured for guiding the sliding movement of an endotracheal tube along the anterior surface between the telescope passage and a patient's lower jaw;
- and
- a guard connected to the distal end of the arm and extending distally therefrom with respect to the inner end of the telescope passage thereby to prevent contact between the inner end of the telescope passage and tissue of a patient into whom the arm is inserted.
An intubation instrument, a portion of which is for insertion into a patient through the patient's mouth, comprising:
- a body having a handle attached thereto;
- an arm attached to the body, the arm having a distal end and being arranged for insertion distal-end first through a patient's mouth and having an anterior surface that faces a patient's lower maw when the arm is inserted;
- a telescope passage carried by the arm and having an inner end located at the distal end of the arm;
- and
- a guide path formed on the anterior surface of the instrument body and configured for guiding the sliding movement of an endotracheal tube along the anterior surface between the telescope passage and a patient's lower jaw;
- wherein the guide path includes a loop protruding from the distal end of the arm, through which loop an endotracheal tube is extendable;
- and wherein the handle is an elongated member that is substantially perpendicular to the arm and wherein the guide path includes a channel formed in the handle and through which channel an endotracheal tube may fit, wherein the length of the channel extends in a direction oblique to the arm and the handle thereby to permit the tube to assume a curved orientation away from the handle and along the anterior surface of the arm.
An intubation instrument, a portion of which is for insertion into a patient through the patient's mouth, comprising:
- a body having a handle attached thereto;
- an arm attached to the body, the arm having a distal end and being arranged for insertion distal-end first through a patient's mouth and having an anterior surface that faces a patient's lower jaw when the arm is inserted;
- a telescope passage carried by the arm and having an inner end located at the distal end of the arm;
- and
- a guide path formed on the anterior surface of the instrument body and configured for guiding the sliding movement of an endotracheal tube along the anterior surface between the telescope passage and a patient's lower jaw;
- and wherein the telescope passage includes an outer end through which a telescope may be passed into the telescope passage, the instrument including a clip mounted near the outer end for releasably retaining a telescope in the telescope passage.
