    Abstract: An illumination device for a speculum may include a first housing part and a second housing part that define a cavity therein. The illumination device may further include a pull tab configured to move from a first position to a second position. When the pull tab moves from the first position to the second position, the pull tab may be disposed so as to allow an electric circuit to be complete so as to provide illumination from an illumination source. When the pull tab is disposed in the first position, the pull tab may be positioned to interrupt the electric circuit such that the illumination device is in an unilluminated state.

  • Patent number: 7563227
    Abstract: 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.

    Abstract: A device for facilitating intubation including an elongate tube inserted in a conventional endotracheal tube. An imaging device (e.g., a nasopharyngoscope) is inserted through the device, and the device is then inserted through an endotracheal tube. The device includes a control wire and handgrip to curve the distal end of the device into an L-shaped configuration, which is produced via a series of interlinked, truncated ring-like elements disposed along the distal portion of the tube. The amount of force applied to the handgrip controls the degree of bend in the distal end of the device. The L-shaped configuration facilitates the proper visualization of the vocal cords by the imaging device.

    Abstract: The invention is a self-retaining disposable laryngoscope having dual light conductive blades that open and lock apart laterally and/or radially. The invention has two curved blades: a tongue blade and a palate blade. These two blades may be separated and locked apart by a ratchet mechanism in the instrument's handle while they remain parallel. This provides a bite block, pushes down the tongue, and makes the invention self-retaining in the airway. The palate blade may be rotated about an axis in the handle of the instrument and locked in position by a ratchet mechanism to spread the distal ends of the blades. This lifts the palate and epiglottis and opens the airway.

A locking mechanism is provided integrally with the laryngoscope which is selectively movable between an unlocked position, in which the blade remains movable between its inoperative and operative positions, and a locked position, in which, upon movement of the locking mechanism to the locked position while the blade is in its operative position, thereafter fixes the blade in the operative position until such time that the locking mechanism is moved to the unlocked position.

  • Patent number: 5584795
    Abstract: A pivoting laryngoscope has a power-driven spatula for performing intubation in patients. The laryngoscope includes a handle for gripping the laryngoscope, and a curved spatula blade having one end connected to the handle. The spatula blade is subdivided into a plurality of adjacent, sequentially arranged sections. At least two of the sections are pivotally connected together at a fulcrum. A motorization assembly is located within the handle and is activatable for generating movement. A motion transmission assembly operatively connects the motorization assembly to at least one of the sections for transmitting the movement of the motorization assembly to the section, whereby the section is moved relative to the fulcrum and within a predetermined arc, thereby changing a curvature of the curved spatula blade.

  • Patent number: 5551946
    Abstract: A multifunctional intubating stylet and laryngoscope, and a method of intubating a patient, comprise a laryngoscope body, and a hollow tubular intubating stylet affixed to and extending generally parallel to the laryngoscope body. An endotracheal tube is mounted on the exterior of the stylet. A guide member is passed through the interior of the stylet and advanced through the patient's vocal cords into the trachea. The endotracheal tube is then advanced along the guide member until it is established in a desired location in the patient's trachea to permit ventilation of the patient.

  • Patent number: 5542904
    Abstract: A handgrip for an electro-optical diagnostic-device set comprises a tubularly-shaped battery housing (10) for receiving variously-shaped energy sources (31, 33, 36, 38) therein to energize a lamp of an instrument head at a second end of the tubularly-shaped battery housing. There is a set of releasable end covers 40 for an opposite, first, end of the tubularly-shaped battery housing, with each of the end covers having a substantially identical cover attaching element (42) as that of the other end covers for mating with an opposite housing attaching element of the housing, but with each end cover being shaped differently from the other end covers, so as to accommodate an energy source different from energy sources accommodated by the other end covers.

  • Patent number: 5438976
    Abstract: This invention relates to a teeth protector for a laryngoscope blade which protector comprises at least one cushioning device of deformable material deformed around at least one selected surface of the laryngoscope blade and adapted to retain a deformed shape and having a self-adhering surface character adapted to adhere to when pressed upon the selected surfaces which surfaces correspond to surfaces which would contact a patient's teeth if the at least one cushioning device were not used. The teeth protector is adaptable for use with virtually all laryngoscope blade styles. A cushioning device comprising beeswax is particularly useful in the teeth protector.
