Description
- This application is a continuation of U.S. Ser. No. 12/847,915, filed on Jun. 30, 2010, the entire disclosure of which is hereby expressly incorporated herein by reference.
- This application is not referenced in any microfiche appendix.
- The present invention relates to a laryngoscope, more specifically, toward a disposable laryngoscope having a rigid cylindrical body for clearing, visualizing, and accessing, the intubation pathway.
- A laryngoscope is used to assist with the placement of a tube into a patient's trachea to aid with the oxygenation of the patient. The prior art laryngoscope uses either a straight or curved blade that allows for the visualization of the patient's vocal cords which are used for locating the patient's larynx and subsequently the trachea. This reduces the risk of intubating the patient's esophagus which would cause air to be blown into the stomach, causing stomach distension and vomiting not to mention depriving the patient of oxygen, and possibly death.
- The presence of blood, saliva, vomit secretions can interfere with the proper placement of the laryngoscope. Further, in emergency situations, the proper placement of the laryngoscope must be done in a quick and safe manner. However, despite good technique by the health care provider utilizing the laryngoscope described in the prior art, there is still a need for an improved laryngoscope that can be used in difficult or emergency situations in and out of a medical facility.
- The present invention satisfies the needs discussed above. The present invention is generally directed toward a laryngoscope, more specifically, toward a disposable laryngoscope having a rigid cylindrical body for clearing and visualizing the intubation pathway to assist with the intubation of a patient in an emergency situation or a patient known for having difficult intubation capability.
- One aspect of the present invention includes a laryngoscope having a handle, a cylindrical tube and an optical subassembly. The handle has distal and proximate ends and a cavity for the seating of the optical subassembly. Further, the handle can be configured in a bent or straight configuration. A bougie and a suction catheter can be included to create an emergency airway kit to be used by emergency medical services inside as well as outside of a medical facility, i.e. a hospital.
- The cylindrical tube is hollow and also has distal and proximate ends. The proximate end of the handle is in communication with the proximate end of the tube. The optical subassembly is located within the handle and extends into the tube.
- The tube also has openings located at its proximate and distal ends. These openings allow the healthcare provider to visualize the proper placement of the laryngoscope within the patient's mouth and throat. To aid with the insertion of the cylindrical tube, the distal opening is oriented at an angle relative to the vertical cross sectional plane of the tube.
- The tube can be made from a metal, a transparent material or translucent material or a combination of the three. The transparent or translucent material will aid in the illumination of the tube along its entire length which will also aid in the proper placement thereof. This is important in those emergency situations where they be excessive bleeding and/or vomiting which may quickly come up the laryngoscope thereby not obstructing the light source. Further, a suction catheter can be used to assist with the removal of the excessive blood and/or vomit from the patient's airway.
- One aspect of the optical subassembly includes a light source located within the handle, a power source such as one or more batteries located also within a handle and in communication with the light source. A light carrier such as a fiber optic cable is in communication with the light source and extends from the handle into the tube wherein it produces light so that the healthcare provider can see the tube and into the patient's mouth and throat to aid in the proper placement thereof. In difficult intubation patients or those in an emergency situation, the health care provider passes a bougie through the laryngoscope between the vocal cords and into the trachea. The laryngoscope is removed, and the endotracheal tube (which allows ventilation of the patient) is guided over the bougie into the trachea to gain safe and quick control of the patient's airway.
- Another aspect of the present invention includes the tube as described above with the addition of a strip of protective material located along the tube proximate to its proximate end. The inclusion of this material is to protect the patient's teeth during use. The material can be made from a rubber or other flexible type of material.
- Another aspect of the present invention includes the tube as described above further having side ports that can be used for suction and/or jet intubation.
- Another aspect of the present invention includes the laryngoscope tube as described above but is configured to be connectably attached through existing laryngoscope handles. This connection can be swivel and/or hinged and can be removable.
- Another aspect of the present invention includes a method of using the laryngoscope tube as described above to secure the airway of a patient. In a difficult or emergency situation where the visualization of a patient's larynx is impaired, the medical provided holds the inventive laryngoscope by the handle and inserts the cylindrical tube into the patient's throat, looking through the cylindrical tube until the larynx is visualized. At that point, a bougie is inserted through the cylindrical tube between the patient's vocal cords and into the patient's trachea. The inventive laryngoscope is removed along the bougie, leaving the bougie in place. The bougie can then guide an endotracheal tube into the patient's trachea. Once in place, the bougie is then removed and the endotracheal tube can be used to ventilate the patient.
- Upon reading the included description, various alternative embodiments will become obvious to those skilled in the art. These embodiments are to be considered within the scope and spirit of the subject invention, which is only limited by the claims which follow and their equivalents.
