A scope adapted for insertion and manipulation in a difficult pathway is disclosed. The scope comprises at least one module for manipulating the scope. The scope may further comprise an illumination source, an image sensor, a power source, and a viewing member for viewing images of a cavity or other anatomical member of a patient. In one embodiment the scope is intended to facilitate insertion of an intubating device, which comprises an elongated semi-rigid stylet including first and second ends and at least one inner lumen connected to a module. Additionally, a flexible tip is provided for manipulating one end of the scope and allowing greater flexibility when maneuvering a difficult pathway. In another embodiment, fluids are provided through an interior portion of the scope, allowed to at least partially contact the lens located at the distal end of the scope, and subsequently cleanse or defog the lens for improving vision via the scope. A method for navigating a difficult pathway and for using the apparatus described herein is also disclosed.

Video laryngoscope system including a video laryngoscope having a laryngoscope handle and a laryngoscope blade. The video laryngoscope system includes an image capture module with at least two stationary imaging units spaced apart along the laryngoscope blade for providing real-time video streams of a patient's airway passage during an intubation and a controller for enabling a clinician performing the intubation to select one or more of the real-time video streams for real-time display on a display screen to assist intubation of a patient.

A system and method of training the proper placement of an endotracheal tube in a training manikin's trachea using a live video camera located inside the manikin for simultaneous remote display of the manikin's trachea and surrounding area and the relative positioning of the laryngoscope blade and endotracheal tube. The system includes a training manikin, a micro video camera mounted adjacent the nasal cavity of the manikin, with the camera directed at the trachea, a monitor displaying the images being captured by the video camera, and electrical connection connecting the video camera to said monitor.

A laryngoscope 10 includes an elongate blade 20 for insertion into the patient, a handle 12 for manipulating the blade, and a connecting member 30 interconnecting the blade and the handle. The handle axis 14 is laterally spaced from a plane of a blade axis 22 such that the handle is exterior of the patient's mouth when manipulating the blade. In one embodiment, the connecting member 30 has a connecting member axis 34 angled at about 90° relative to the plane of the blade axis 22. The laryngoscope blade is removably connected to the handle, and is fixably secured to the blade.

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.

A laryngoscope blade is detachably connectable to a hook-on-type laryngoscope handle in conformity with International Standard ISO-7376-1 or ISO 7376-3. The blade comprises a rigid housing having a lower, tongue-engaging flange section extending along the length thereof, a proximal base end provided with hooks or fittings for engaging complementary handle hooks or fittings in compliance with ISO-7376-1 and ISO-7376-3, the proximal base being provided with a hook or flange of such length that the hook or flange comes into contact with the top of the handle such that the blade is prevented from rotating downwardly to such a degree that the distal end of the blade comes into contact with the side of the handle and enabling the blade to be elevated into an operating position to maintain conductivity for powering a light source for the blade.

A metal laryngoscope blade with a resiliently elastically deformable metal blade hook-on fitting for removable double snap engagement into an operative intubation position on a laryngoscope handle with a correspondingly sized handle hook-on fitting.

The present invention concerns improved laryngoscope blades, particularly for use in the intubation of patients, for example orotracheal and nasotracheal intubation, and which allow viewing of a portion of the mouth, the pharynx, and the larynx of a patient, and depress the tongue and the structures of the floor of the mouth in order to prevent the tongue of the patient from obstructing the view during examination.

In one embodiment, the present application discloses a laryngoscope blade assembly comprising a blade body and an elastomeric material configured on the blade body, wherein the elastomeric material is permanently adhered to the lower surface, the upper surface or both the lower and the upper surfaces.

The invention discloses a laryngoscope. The laryngoscope comprises a handle and a laryngoscope blade, wherein the handle and the laryngoscope blade form an L shape, a camera is arranged at the end part of the laryngoscope blade, a display which is used for displaying images photographed by the camera is arranged on the handle, a regulating mechanism which is used for regulating the depth of the laryngoscope blade in a throat is arranged between the handle and the laryngoscope blade and comprises a regulating gear and a gear rack, a regulating window and a gear rack accommodating groove are formed in the handle, the regulating gear is rotatably arranged in the regulating window, the gear rack accommodating groove communicates with the regulating window, one end of the gear rack is fixedly connected with the laryngoscope blade, the other end of the gear rack is arranged in the accommodating groove in a sliding manner, and the gear rack is engaged with the regulating gear. The laryngoscope is simple in structure, the position of the laryngoscope blade in the throat can be fine-adjusted up and down, and thus, the laryngoscope can more efficiently work at throats of patients.
