A tracheal device for the assisted respiration of a patient includes a first tube having a proximal end to be arranged protruding from the mouth of the patient and connectable to a device for assisted respiration, a distal end adapted to cover an orifice, and a first sealing element coupled externally to the first tube. The tracheal device also includes a second tube having a distal end adapted to cover the orifice, a second sealing element coupled externally to the second tube, and a flexible and collapsible service duct stably coupled to the first tube and the second tube to allow the service duct and the first and the second tubes to be arranged in two configurations.

A fluid delivery and airway management device including a tubular member dimensioned for introducing a fluid into a trachea of a mammal, the tubular member having a proximal portion, a distal portion, and a middle portion between the proximal portion and the distal portion. The tubular member is dimensioned for positioning of the proximal portion in an oral cavity of a mammal, the middle portion in an oropharynx of the mammal and the distal portion in an esophagus of the mammal. An inflatable oral cavity balloon is positioned at the proximal portion and dimensioned to occlude the oral cavity. An inflatable esophageal balloon is positioned at the distal portion and dimensioned to occlude the esophagus. Apertures may be formed within the middle portion such that a fluid introduced into the tubular member is output through the apertures to a trachea.

An articulating tracheoscope control device, a laryngeal mask airway (LMA) device, and an articulating tracheoscope control device and LMA device combination system, that can control precise movement of a distal end of a tracheoscope with a patient's larynx within an angular range of at least 180 degrees and can lock the distal end of the tracheoscope in any desired position within the patient's larynx such that managing the tracheoscope during a tracheostomy procedure is not required in order to monitor the tracheostomy procedure.

An intubation device utilizes a steerable endotracheal tube guide, a novel mechanism to automatically position an endotracheal tube at the laryngeal opening, and a novel system for soft tissue retraction to improve visualization of the laryngeal opening. An ETT is positioned within an overtube having proximal and distal ends and a flexible tip. The distal end houses a feeder mechanism for displacing the endotracheal tube through the overtube. A hood includes a stem, base, and expandable body, and may be affixed to the overtube's distal end. The ETT-containing overtube is precisely positioned at a laryngeal opening via positioning effects of body expansion, activation of a tip director, and/or flexible tip articulation. Unhindered visualization of the laryngeal opening is achieved by the expandable body, pushing the soft tissue outwardly and extensibly. An actuation module controls the feeder mechanism as well as the flexible tip to position flexible tip and endotracheal tube.

A laryngeal mask airway (LMA) intubation guide for use in an endotracheal intubation procedure and in ventilation of a subject, the LMA intubation guide including: an elongate body defining a passageway extending between a proximal opening and a distal opening, for receiving a blade portion of an intubation device; a laryngeal mask at the distal opening, for covering the larynx of the subject; and a ventilation airway extending at least partially along the body, including: a ventilation port at a proximal end of the ventilation airway for connection to a ventilator; and a ventilation aperture at a distal end of the ventilation airway for allowing fluid communication between the ventilation airway and the passageway proximate to the laryngeal mask, the LMA intubation guide being configured to allow intubation of the subject using an endotracheal tube through the passageway, while the subject is ventilated using the ventilation airway.

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. A novel endotracheal tube and novel indwelling catheter also incorporating a balloon component are also disclosed.

Laryngeal mask comprising a dome and a connecting channel configured to produce the artificial ventilation of a patient, wherein the laryngeal mask further comprises an inlet of a gastric aspiration tube, said inlet being located at a distal end of said dome, on the side wall of this dome, wherein said inlet is configured to absorb any gastric secretions from the patient's oesophagus, wherein the laryngeal mask comprises at least a non-return valve located at the distal end of the dome, wherein the valve comprises at least two flexible membranes configured to allow fluid to flow in a single direction from the outside to the inside of the dome, wherein the pipes of the connecting channel connecting the dome with the artificial respirator outside have in their section a geometric configuration classified as an irregular, asymmetric and non-circular polygon.

Nasal tracheal devices include a tube with visual indicia of insertion depth corresponding to patient height and an inflatable cuff. The tube comprises or provides a plurality of lumens that are in fluid isolation including an airpath lumen and a pressurized fluid source for inflating the cuff. The devices may also be configured to suction patient fluid from a location adjacent and/or above the cuff.

Provided is a laryngeal mask airway, comprising a laryngeal mask airway main body (10) and a view device (20). The laryngeal mask airway main body (10) comprises a catheter (12), and a sealing base (13) connected to the distal end of the catheter (12), and the view device (20) comprises a control part (22) and a vidicon (23), wherein an image sensor (231) is formed at the distal end of the vidicon (23), and an air guide channel (101) and a view lumen (103) are formed in the laryngeal mask airway main body (10); and a first blind end part (103a) that is closed by a light-transmitting material is formed at the distal end of the view lumen (103), the vidicon (23) is inserted into the view lumen (103) in a pluggable manner, the distal end of the view lumen (103) and the distal end of the vidicon (23) extend into the sealing base (13), and the distal end of the vidicon (23) can be bent and reset. The vidicon (23) is sealed inside the view lumen (103) and does not come into contact with internal tissue of a patient during use, such that the vidicon (23) can be reused in a relatively safe manner; and the distal end of the vidicon (23) can bypass the epiglottis, and the drooping epiglottis can be pushed aside by means of controlling the distal end of the vidicon (23) to be bent upwards so as to obtain a good view.

Embodiments of the invention relate to a ventilation device comprising: a. a ventilation tube having proximal and distal ends; and b. an inflatable cuff having a proximal bulge portion and a distal neck portion disposed distal to the bulge portion, the inflatable cuff being mounted around the ventilation tube to define proximal and distal cuff attachment locations which are both fixed on an outer surface of the ventilation tube.
