Means Placed In Body Opening To Facilitate Insertion Of Breathing Tube Patents (Class 128/200.26)
  • Patent number: 11350817
    Abstract: The present invention is a system and method for water cycling colonoscopy that includes a colonoscope with a water ejection system and a camera, and a rectal overtube that receives the colonoscope therein. The overtube is placed in the anus and has a vacuum port outside the anus that attaches to a vacuum source. The overtube vacuum port vacuums water emitted by the colonoscope while the colonoscope is moving through the colonic lumen to control the amount of fluid in the colonic lumen. The overtube may be fitted with structures to improve the fit and attachment to the anus, including an inflatable cuff and a flexible skirt.

  • Patent number: 11241147
    Abstract: A guided tracheal intubation system using an autonomous modulated light source, outputting modulated illumination at a constant level, and externally applied to the subject's larynx region. An optical imaging system receives a video stream from within the subject's throat, including modulated illumination from the subject's trachea. A display control system performs signal processing on the modulated content of the images, and outputs frames of those images in which the intensity level of illumination from the trachea can be controlled without any need to change the illumination output from the modulated light source. The light source has no connection with the rest of the system, and need contain no more than a battery, a power supply circuit and a light source. It can therefore be of low cost and can be made disposable, such as in the form of an adhesive patch applied to the subject's neck.

  • Patent number: 10456542
    Abstract: A novel nasogastric tube, that when properly inserted within a person, blocks the esophagus of the person to prevent gastric contents from being aspirated. The tube can be left in place during direct langroscopy and the device can include a preferably inflatable balloon for obstructing the person's esophagus. This balloon can be preferably provided on a slidable tube that allows for head movement/flexion without movement of the balloon placement. The tube can be a dual or single lumen device. With a duel lumen device, a first lumen can be connected to a suction tubing to suction gastric contents from the distal end of the tube, while the other lumen can open up above the cuff to allow for easier ventilation with a bag valve mask/BVM.

    Abstract: An insertion guide facilitates insertion of an endotracheal tube (ETT) into the trachea of a patient instead of the esophagus of the patient. The ETT includes an elongated, somewhat flexible, generally hollow tube and the insertion guide includes an elongated, solid and relatively rigid shaft that is configured to be positioned within the hollow tube of the ETT. The shaft is provided with a radiused portion and/or an angled portion adjacent a distal end of the insertion guide that protrudes outwardly beyond a distal end of the ETT. The radiused portion and/or the angled portion of the shaft facilitate insertion of the distal end of the ETT past the epiglottis and into the trachea of the patient instead of into the esophagus of the patient.

  • Patent number: 10413689
    Abstract: An oropharyngeal airway for use during diagnostic and surgical procedures, comprising a body with a proximal and a distal end. The distal end is sized for insertion through a protective bite block disposed in a patient's mouth. Both sides of the distal end are tapered to a curved distal edge. A flange is transversely opposed at the proximal end, preventing the proximal end from moving through the protective bite block and into the patient's mouth. An elliptically-arched channel in the shape of a lingual contour extends from the proximal end to the distal end. The channel includes a pair of tapered upstanding walls that guide the passage of a surgical instrument through the space between them. The oropharyngeal airway can be constructed of recyclable or biodegradable materials and is compatible with protective bite blocks of all sizes.
