Abstract

An airway intubation device having a one-piece molded body of biocompatible material with an ergonomically designed hand piece for left hand manipulation. The body includes a cap piece and linear-curved-linear insertion piece having a channel in one side thereof for insertion of an endotracheal tube. The channel has a wide entry portal disposed ahead of the hand piece so that a clinician may load the channel with a tube while the insertion piece is in the mouth of the patient without having to view the entry portal. The device may include a viewing system with a camera so that a clinician can view the insertion of the tube between the vocal cords of a patient without contact.

Dependent claims

An airway intubation device for permitting a clinician to indirectly view a patient's vocal cords, the airway intubation device comprising:

a hand piece;
an insertion piece having a first end and a second end opposite the first end, the insertion piece including a first linear portion having a first axis, contiguous with a curved portion, contiguous with a second linear portion having a second axis inclined at a predetermined angle relative to the first axis, the second linear portion including a truncated tip which includes a flange member blunting the truncated tip to avoid tissue damage during intubation, the hand piece and the insertion piece comprising a rigid single body of thermoplastic material;
the insertion piece further including a bore extending from the first end to the second linear portion and an endotracheal tube channel next to the bore, such that a lateral plane intersecting the endotracheal tube channel and the bore is perpendicular to a second plane encompassing the first axis and the second axis, the endotracheal tube channel having an open slot on a side of the endotracheal tube channel such that if an endotracheal tube is positioned in the endotracheal tube channel, the endotracheal tube is between the open slot and the bore, wherein the endotracheal tube channel has an entry portal extending along the first end and terminating before the curved portion, and an exit portal extending along the second end, wherein the entry portal has a proximal end axially opposite a distal end, and wherein the proximal end of the entry portal is substantially wider than the distal end of the entry portal and the endotracheal tube;
disposed within the bore at the second linear portion, an illumination system including a light emitting diode for illuminating the patient's vocal cords, and an image gathering system including a camera;
an image viewing system including a video display screen electrically connected to the camera;
and
an energy source retained in the hand piece and powering the image gathering system, the image viewing system and the illumination system.

An airway intubation device for permitting a clinician to indirectly view a patient's vocal cords, the airway intubation device comprising:

a hand piece having a longitudinal axis;
an insertion piece having a first end and a second end opposite the first end, the insertion piece including a first linear portion having a first axis, contiguous with a curved portion, contiguous with a second linear portion having a second axis inclined at a predetermined angle relative to the first axis, the second linear portion including a truncated tip which includes a flange member blunting the truncated tip to avoid tissue damage during intubation, and further including a bore extending from the first end to the second linear portion, the hand piece and the insertion piece comprising a rigid single body;
disposed within the bore at the second linear portion, an illumination system including a light emitting diode for illuminating the patient's vocal cords, and an image gathering system including a camera;
an endotracheal tube channel next to the bore such that a lateral plane intersecting the endotracheal tube channel and the bore is perpendicular to a second plane encompassing the first axis and the second axis, the endotracheal tube channel having an open slot on a side of the endotracheal tube channel such that if an endotracheal tube is positioned in the endotracheal tube channel, the endotracheal tube is between the open slot and the bore, the endotracheal tube channel having an interior geometry with three points of contact between the endotracheal tube and the interior geometry, wherein the endotracheal tube channel has an entry portal extending along the first end and terminating before the curved portion, and an exit portal extending along the second end, wherein the entry portal has a proximal end axially opposite a distal end, and wherein the proximal end of the entry portal has a flared width and is substantially wider than the distal end of the entry portal and the endotracheal tube;
an image viewing system including a video display screen electrically connected to the camera;
and
an energy source retained in the hand piece and powering the image gathering system, the image viewing system and the illumination system.
