Instrument for direct laryngoscopy with a rigid blade and flexible fiberoptics
View Patent ↗A laryngoscope and flexible viewing device having means to carry an endotracheal tube into a patient and method of using the device are provided. The device allows a single user to view the interior of a patient's anatomy and change the view to better determine the path for intubation. The device can be used by a single individual to simultaneously open the pathway to a patient's trachea and then deliver an intubation device, such as an endotracheal tube, without the assistance of another person. The device provides several options for the practitioner to both visualize the patient's larynx and deliver an endotracheal tube into the trachea, especially in patients considered to have difficult anatomy to intubate. The viewing device in a preferred embodiment is a fiberoptic scope and the device includes a pivoting means to allow the viewing means to provide a more panoramic view of the patient's throat area.
1. A laryngoscope and flexible viewing device with intubation means, comprising:
a handle operationally attached to a viewing member and a laryngoscope blade;
the viewing device comprising a flexible tube having a viewing device, the flexible tube further having means for providing a variable angle view of the interior of a patient's anatomy, the flexible tube being operationally attached to the viewing member and carried adjacent the laryngoscope blade, the flexible tube including a guidewire to guide the intubation device, the guidewire including an end piece pivotal from a first parallel to the guidewire position to a second perpendicular to the guidewire position to keep the guidewire attached to the laryngoscope and flexible viewing device;
the device having means to cause, when desired, the distal end of the flexible tube to pivot to any angle in a range from a linear position to a first pivoted position and back through the linear position to a second pivoted position opposite the first pivoted position;
the laryngoscope blade comprising a rigid element for effecting the opening of a passageway for an endotracheal tube; and
means to carry an intubation device adjacent the flexible tube such that the user alone may view the interior of the patient's anatomy, provide an open passageway and deliver an intubation device.
2. A laryngoscope and flexible viewing device with intubation means, comprising:
a handle operationally attached to a viewing member and a laryngoscope blade, the viewing member being rotationally attached such that it can be pivoted from a storage position to an operational position;
the viewing device comprising a flexible tube having a fiberoptic cable and viewing lens operationally connected thereto, the flexible tube further having means for providing a variable angle view of the interior of a patient's anatomy, the flexible tube operationally attached to the viewing member and carried adjacent the laryngoscope blade, the flexible tube includes a guidewire to guide the intubation device the guidewire includes an end piece pivotal from a first parallel to the guidewire position to a second perpendicular to the guidewire position to keep the guidewire attached to the laryngoscope and flexible viewing device;
the device having means to cause, when desired, the distal end of the flexible tube to pivot to any angle in a range from a linear position to a first pivoted position and back through the linear position to a second pivoted position opposite the first pivoted position;
the laryngoscope blade comprising a rigid element for effecting the opening of a passageway for an intubation device; and
means to carry an intubation device adjacent the flexible tube such that the user alone may view the interior of the patient's anatomy, provide an open passageway and deliver an intubation device.
