An artificial airway device (10) of a resilient material for use as a combined obturator and airway device without penetration into a larynx comprising a pre-formed flexible saccular chamber (14) and having a semi-rigid hollow stem (14) projecting from a position at or near one end of the chamber at an obtuse angle and capable of being flexed into a curve that deviates up to 90 degrees from the longitudinal axis of the said chamber, the chamber being provided with one or more openings, and dimensioned and arranged so that in use the chamber is adapted to sealingly engage in a patient's pharynx with at least one opening in communication with the patient's laryngeal inlet and the stem extends into or through the patient's mouth for connection to a breathing circuit.

L'invention porte sur un dispositif artificiel (10) pour voies respiratoires formé dans un matériau résilient et destiné à être utilisé sous forme d'une combinaison obturateur/appareil respiratoire sans le faire pénétrer dans le larynx. Le dispositif de cette invention comprend une chambre sacciforme flexible, préformée (14) pourvue d'une tige creuse semi-rigide (12) faisant saillie du niveau ou à proximité d'une extrémité de la chambre selon un angle obtus et capable de fléchir et prendre la forme d'une courbe déviant jusqu'à 90 degrés de l'axe longitudinal de cette chambre. La chambre est pourvue d'un ou plusieurs orifices, et dimensionnée et agencée de sorte que, en utilisation, elle puisse venir en contact hermétique avec le pharynx du patient, un orifice de la chambre communiquant au moins avec l'orifice du larynx. La tige s'étend dans la bouche du patient pour se raccorder à un circuit de respiration.
