  • Patent number: 10925590
    Abstract: The uvula retractor is an elongate, arcuate body having a hooked handle at one end and a raised platform or flat spoon at the opposite end for lifting the uvula for access to the region behind the uvula. The uvula retractor arm has a plurality of clefts or holes defined therein for hooking the retractor onto a mouth gag once the uvula is properly retracted. A channel housing a fiber optic cable extends along the posterior side of the retractor. A fiber optic connector adapted for attachment to a light source extends from the retractor adjacent the handle. The inferior end of the retractor has at least one rib or support web beneath the raised platform, which supports the lower end of the channel and aims the light emitting end to illuminate the area behind the retracted uvula.

  • Publication number: 20140275784
    Abstract: A conscious sedation airway, CSA, useable during conscious or unconscious sedation. The CSA includes an elongate body with an anterior flange depending therefrom. The body includes a central portion with superior and inferior plates extending a distance beyond a distal end of the body in an inferiorly curved arrangement. A midline opening and two lateral openings extend through the length of the central portion and are configured to receive apparatus, like endoscopes, cannula, and catheters. The superior and inferior plates aid to maintain a position of the tongue and to guide apparatus inserted through the midline opening toward the posterior oropharynx. The anterior flange prevents swallowing the CSA. The body does not extend into the pharynx to enable use in conscious patients and/or those with intact gag reflexes. And a nasopharyngeal airway can be placed without removing the CSA to allow bag ventilation of the patient.

  • Patent number: 6558392
    Abstract: A device and method for distracting a temporomandibular joint and/or repositioning a dislocated disc in a patient. The device comprises upper and lower elongated members that are releasably coupled together by an arrangement that allows pivoting and sliding relative movement. Each member includes a handle at one end and an opposite distal tip configured for engaging teeth of the upper and lower jaws. The lower member includes a clamp for adjustably securing the patient's mandible to the lower member. The device may also include an auxiliary, height adjustable fulcrum located forwardly of the coupling between the members. The auxiliary fulcrum permits the operator to obtain a more advantageous lever, which is useful for freeing a locked jaw in a patient suffering from intra-articular adhesions. The distal tips and/or receptacles mounted on the distal tips may be detachable from a base portion of the device to enhance adaptability of the device to different size patients and anatomies.

  • Patent number: 6244865
    Abstract: A tongue positioning device is disclosed for positioning the tongue within a user's mouth. The device includes a tongue positioning mouthpiece that includes a mouthpiece body with a center hole therein. A flange portion extends around the periphery of the mouthpiece body that forms an acoustic seal with the teeth and lips of a patient during use. A pair of bite blocks protrude from the mouthpiece body on opposing lateral sides of the center hole. A tongue bridge is fixedly secured to the bite blocks via a pair of downwardly extending arms. The tongue bridge includes a platform area where a patient's tongue is placed under when the mouthpiece is used. A cylindrical portion extends from the mouthpiece body in a direction away from the flange. An optional filter is removable from the cylindrical portion and acts as a protective barrier for viruses, bacteria, microbes, and other pathogens. The filter includes a removable filter body containing a filter media.

  • Patent number: 6234962
    Abstract: A one-piece equine dental speculum having an open frame, extending from one side of a horse's mouth, across in front of the incisors to the opposite side of the mouth. Bite plates are affixed at the front of the speculum to engage the incisors when the speculum is fully inserted. Two V-shaped projections extending rearward from each end of the bite plates act as wedges to engage the incisors and force them towards the upper and lower bite plates, forcing the jaws apart. Simply, insertion requires placing the speculum frame around the horse's mouth, placing the V-shaped projections between the upper and lower incisors and pushing until the incisors are “walked” along the upper and lower surfaces of the V-shaped projections to open the jaws. Once fully inserted, the incisors are held in place at the bite plates preventing the jaws from closing. Nose and head straps hold the speculum in place in the horse's mouth.
