  • Publication number: 20140378770
    Abstract: A Glottiscope for assisting with the insertion of an endotracheal tube or an Eschman like stylet into a patient is claimed. The Glottiscope comprises a blade which defines an internal passage for receiving an endotracheal tube or an Eschman like stylet, the blade having a proximal end and a distal end and means for viewing the patient's glottis, wherein the viewing means is disposed at the distal end and in use, below the point of emergence of an endotracheal tube or a stylet/guide (to rail road the endotracheal tube) in the internal passage to provide a view of the patient's glottis, the blade being adapted to direct the viewing means towards the centre of the patient's glottis.

  • Patent number: 8337402
    Abstract: An improved laryngoscope blade for use with a conventional laryngoscope handle and conventional means of illumination. The blade tapers from the handle end to the end that is inserted in the mouth, so that the blade roughly conforms to the shape of the tongue. In addition, the sides of the blade curve upward so as to cradle the tongue. This design allows the intubator to better control the tongue and more easily view the vocal chords during insertion of an endotracheal tube. Furthermore, the ambidextrous, symmetrical design is easier for left-handed doctors and technician to use.

  • Patent number: 7214184
    Abstract: One aspect of the present invention provides a laryngoscope comprising a blade; a doployable mirror, and an operating mechanism, the operating mechanism being arranged to deploy the mirror. The mirror is pivotable with respect to the blade and the arrangement is such that an initial operation of the operating mechanism causes the mirror to be deployed while further operation of the operating mechanism causes the mirror to be pivoted with respect to the blade. In the preferred embodiment, the blade has a pivotable tip which is also operable by the operating mechanism. The deployment of the mirror, the pivoting of the mirror 30 and the pivoting of the tip 18 can all be performed by operation of a single operating mechanism, preferably in the form of a simple lever. The laryngoscope may therefore readily be operated using only one hand and without the need for any dextrous finger movements.

  • Publication number: 20030207229
    Abstract: An ergonomic non-obstructive illuminated examination mirror for dentistry, medicine and surgery, without the need of fiber optics, includes a slim line elongated member having a wire connection passage, a weighted first proximal end with a battery chamber and a second distal end. A removable disposable non-fogging angled reflective mirror head is coupled to the second end of the elongated member. Light to the mirror is provided by a low heat emitting light source attached to the second end of the rod directed toward the angled reflective head. The power source is connected to the low heat light source by one or more conductive wires within the wire passage and a switch, thereby forming a circuit with the power source and the light source, which is activated by a switch connected to the conductive wire connection.

  • Patent number: 6135948
    Abstract: A convertible laryngoscope includes a deployable integral mirror to allow the doctor to clearly view the larynx and more easily insert an endotracheal tube. In many patients, due to injury, deformation, or an existing medical condition, the introduction of the endotracheal tube can be a prolonged and difficult affair, the doctor being forced to work blind when they cannot gain an unobstructed view of the larynx and the path that the cannula or tube needs to travel during intubation. The present invention addresses this problem by providing the above mentioned mirror, which is disposed in a first position proximate the laryngoscope blade during the initial introduction of the blade into the patient's mouth. Once the base of the tongue is reached and depressed, the user may deploy the mirror into a second position extending towards the soft palate that allows a reflected view towards the larynx and epiglottis.

  • Patent number: 5973728
    Abstract: A miniature video camera (18) mounted on a pair of goggles (12) that substantially captures the monocular perspective of the operator's right eye during the medical procedure of direct laryngoscopy and tracheal intubation. The camera is connected to a pentaprism (14) that the operator aligns with the area of interest by slight changes in head position and reference to alignment bands (46) alongside the prism body. The image is reflected through the pentaprism to the camera and then displayed on a nearby video monitor (38). Auxiliary light sources or specialized equipment are not required. Persons other than the laryngoscopist can see the procedure as it is being performed. The pentaprism, camera, and camera mount do not significantly interfere with the operator's vision or performance of direct laryngoscopy or other procedures.
