  • Patent number: 10709322
    Abstract: A laryngoscope with integrated and controllable suction includes a handle and a blade. A suction port is at the proximal end of the handle and is configured for connection to an air source. The suction port defines an opening into one or more air flow paths defined through the laryngoscope, which each terminate at one or more intake ports. In some embodiments, a valve is interposed into each air flow path to regulate air flow along each air flow path. Such a valve is operably connected to a switch mounted on an exterior surface of the laryngoscope, such that manipulation of the switch causes the valve to open or close, thus allowing the physician or other medical professional to control the air flow and selectively apply constant or intermittent suction.

    Abstract: A suction unit is placed inside the handle of a laryngoscope to allow portable suction to be utilized during intubation without requiring multiple devices. The suction tip can be attached to the distal end of the laryngoscope blade. Replacing the light on a laryngoscope with an LED allows for a small watch-sized battery to be used instead of current large batteries taking up the handle space. This opens up the handle space to make room for the suction unit. Evacuated fluids and discharge exit into a tube and into a portable receptacle.

  • Patent number: 6955645
    Abstract: An element for a phonomicrosurgical modular glottiscope system comprises a proximal end; a distal end; a pair of opposing curved sides intersecting at an apex line; a substantially planar base, and internal channels disposed within the base. The base plate is removably attached to the pair of curved sides, and the base and curved sides define a lumen extending from the proximal end to the distal end. The internal channels include a first internal channel that provides illumination to the distal end and a second internal channel that provides aspiration to the distal end. In operation, the distal end of the element is inserted into a body cavity and the lumen provides visualization of the distal end and access to the distal end for tools inserted into the lumen from the proximal end. A method of manufacturing the element is also disclosed.

  • Patent number: 6106458
    Abstract: An anesthetic laryngoscope for manual oxygen jet-ventilation, including a handle with a handle housing having a lower end, a first oxygen supply tube, and a battery container mounted in the handle housing. A blade having an observation light and a second oxygen supply tube mounted thereon is mounted on the lower end of the handle means. The first oxygen supply tube is connected to the second oxygen supply tube, and a manual oxygen on/off valve is provided on one of the first and second oxygen supply tubes. Preferably, the manual oxygen on/off valve is a manually controlled two-position, two-way valve to enable generation of a pulsing supply of oxygen through an ejector nozzle at the end of the second oxygen supply tube.

  • Patent number: 5702351
    Abstract: A disposable laryngoscope blade connects to a handle especially to facilitate endotracheal intubation of a patient. The blade includes a base portion that attaches to the handle, and an elongated blade portion extends from a proximal end to terminate in a distal tip. The blade portion is arcuate and flattened so as to have a flat upper wall and a flat lower wall joined at lateral edges, and the lateral edges converge toward the distal tip. The blade includes a passageway therethrough so that a vacuum source may attach to a nipple near the proximal end and an inlet port is formed near the distal tip so that fluids may pass through the blade portion. The handle carries a battery power source and electrical contacts. The base portion of the blade also has contacts so that, when the blade is mounted a circuit is completed to power a light source disposed on the blade portion.

  • Patent number: 5665052
    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: 5571071
    Abstract: An improved laryngoscope blade is described wherein the blade includes an anesthetic-containing reservoir. In a first preferred embodiment for providing an anesthetic spray at the distal end of the blade, the blade includes a conduit for providing fluid communication between the reservoir and the distal end of the blade and a fluid delivery means for expelling the anesthetic from the reservoir and for propelling it through the conduit. In a second preferred embodiment for providing an anesthetic gel to the upper surface of the blade, the blade includes a fluid conduit manifold for providing fluid communication between the reservoir and the upper surface of the blade. In an alternative preferred embodiment for providing an anesthetic gel to the tipper surface of the blade, the blade includes a porous layer located on the upper surface of the blade, the porous layer being adapted to contain an anesthetic gel.
