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.

The present disclosure relates to airway devices. It is applicable to supraglottic devices including laryngeal airway devices and to their methods of manufacture. The present disclosure is particularly applicable to laryngeal airway devices for human and veterinary use. The device includes an airway tube having a distal end and a proximal end, the distal end of the airway tube is provided with a pre-formed and non-inflatable peri-pharyngeal bowl. The peri-pharyngeal bowl includes a posterior bowl portion having a back dorsal portion and a side wall extending around and depending from the periphery of the back dorsal portion to define an internal space, and further includes a resiliently deformable flange extending laterally from the side wall of the back dorsal portion which defines an extended internal space, the resiliently deformable flange has inner and outer surfaces that extend to a circumferential edge.

The invention is an endotracheal intubation for preventing injury to throat, vocal cords and trachea. The endotracheal intubation comprises a hollow intubation body with a variable outer diameter. The hollow intubation body comprises a front end and a tail end, an inner intubation wall and an outer intubation wall, and having a retracted state with a smaller outer diameter and an expanded state with a larger outer diameter. When the endotracheal intubation inserted into a patient’s trachea needs to be replaced, as long as the hollow intubation body of the new endotracheal intubation is in the retracted state, it can be inserted into the hollow intubation body to be replaced, and when reaching the position, the hollow intubation body to be replaced is withdrawn, and finally the new hollow intubation body is changed into the expanded state, i.e. the replacement operation of the endotracheal intubation is completed.

An airway management device comprising a body having a proximal end for receiving an oxygen supply tube and an distal end for insertion into a trachea of a patient; said body including a linear portion adjacent to the proximal end and a curved portion adjacent to the distal end; said body including an external shell and having a first bore through said shell for receiving the oxygen supply tube; wherein flexural strength for said airway management device is provided by said shell.

The add-on device senses moisture at a distal end of the add-on device, and in case of detection of excessive wetness, provides suction to the distal end of the device through a cavity passing along the device, the suction is provided via a suction outlet channel extending from a proximal end of the device.

A neonatal laryngeal mask airway (NLMA) can be used for airway management in the neonate in emergent situations, e.g., respiratory distress syndrome after premature birth, and nonemergent situations, e.g., elective surgery. The NLMA includes a back plate and a cuff. The back plate provides a shelf, a back plate opening, and a wall, which is perpendicular to the shelf, that surrounds a portion of the back plate opening. The cuff is coupled completely around a perimeter of the back plate. The cuff is configured for inflation from an uninflated state to an inflated state in a patient with a pharynx, a larynx with a laryngeal inlet, and a trachea. In the inflated state, the cuff forms a seal around the laryngeal inlet to isolate the larynx from the pharynx, and the back plate is configured to guide a catheter inserted through the back plate opening into the trachea.

A medicament delivery device (“MDD”) having a delivery tube and a laryngeal mask having an anterior patient-contacting surface. In some embodiments of the invention, the laryngeal mask has an epiglottis-holding ridge. In some embodiments of the invention, the laryngeal mask has a cuff-portion providing at least a portion of an anterior patient-contacting surface, the cuff-portion being shaped and positioned to create a side-groove facing away from the anterior patient-contacting surface. In some embodiments of the invention, the laryngeal mask has a plurality of ridges on a posterior-side of the laryngeal mask opposite the anterior patient-contacting surface (the “posterior-side ridges”), the posterior-side ridges being shaped and positioned relative to the anterior patient-contacting surface so as to push against the patient and thereby push the anterior patient-contacting surface against the patient.
