  • Patent number: 8444556
    Abstract: The present invention is a self-retaining laryngoscope composed of a palate brace or blade, a slider, and a tongue blade. The angulated tongue blade puts less force on the blade, reduces trauma, and is not conducive for mechanical failure. The slider interacts with the tongue blade by widening the opening of the mouth, and acts as a bite block. The fenestrated palate blade provides an unobstructed view of the vocal cords during intubation, and allows removal of the laryngoscope over the endotracheal tube without displacing it. The result is a laryngoscope that requires only one hand to use properly, and has superior retraction due to its shape.

The proximal end of the upper blade has a grip portion which can be moved closer to or farther away from the handle attached to the proximal end of the lower blade to open or close the distal ends of the lower and upper blades. The lower blade of the invention has a distal end adapted as an esophageal obturator for obstructing the esophagus. An arytenoid bumper to prevent the laryngoscope from penetrating too far into the esophagus is preferably secured to the distal end of the lower blade. The arytenoid bumper may have a ramp or wedge shape adapted to deflect an intubation tube through a patient's larynx and into the trachea.

  • Patent number: 7458932
    Abstract: A tongue stabilizer includes a tongue-engaging plate that is held on a laryngoscope blade by pressure sensitive adhesive, with a foam strip in-between to compensate for any irregularities between the tongue-engaging plate and the laryngoscope blade. The tongue-engaging plate is cup shape to cradle the tongue to prevent the tongue from interfering with the visibility and process of intubation. A protective strip can be used to cover the adhesive.

  • Publication number: 20080275306
    Abstract: A composite anoscope for ano-rectal diagnostic and surgery, wherein the anoscope (2) also comprises an internal component (1), to be inserted therein, and a suitably shorter external component (3), ending with a conic frustum mantle (18), wherein the anoscope (2) is to be inserted. The three components (1, 2, 3) are all conic frustum shaped hollow bodies having circular cross-section. The internal component (1), when inserted in the anoscope (2), forms therewith a single body having a compact and smooth external surface and an ogival tip. The external component (3) is provided close to its mouth with slotted wings (19, 20), to be fixed to the perianal skin for securing the whole composite anoscope during the diagnostic and surgical operations.

    Abstract: A rigid laryngoscope apparatus has a first and second elongate linear hinge portions joined in mutual coaxial rotation between proximal and distal ends. A first elongate linear handle is connected by a first handle arm to the proximal end of the first hinge portion, and a first blade is connected to the distal end of the first hinge portion. A second elongate linear handle is connected by a second handle arm to the proximal end of the second hinge portion, while a second blade is connected to the distal end of the second hinge portion. The handles are oriented in mutually parallel juxtaposition extending laterally away from the hinge portions and the blades so as to not obstruct the oral cavity.

  • Patent number: 7044910
    Abstract: The present invention relates to the field of medical devices used in the procedures of orotracheal or nasotracheal intubation. Oral or nasal endotracheal intubation procedures are commonly employed to secure a controlled airway and to deliver inhalant oxygen, anesthetic gases, and other therapeutic agents into the trachea and lungs of human and veterinary patients. Such intubation procedures carry a significant risk of dental injury resulting from contact between the laryngoscope blade used for visualization during intubation. The present invention provides an apparatus to reduce dental injury including a modified laryngoscope blade and a disposable insert which is designed to be received and retained in a single step by the modified laryngoscope blade. The disposable insert may be quickly secured by the user, and reduces both direct pressure and shear forces on the maxillary incisor teeth when the laryngoscope blade is placed in a patient's mouth during intubation.
