A respiratory mask (10) provides improved sealing through the use of an intraoral mouthpiece (12) with a large sealing area. A tubular extension (22), configured at one end to accept standard respiratory fittings, is the conduit for gas delivery to the intraoral mouthpiece. The respiratory mask may also include an intraoral oropharyngeal airway (50) which flexes so that it can be inserted without the need for rotation or use of a tongue blade. The respiratory mask may also include an external shield (58) to enhance sealing and provide a barrier of protection for the healthcare provider. The mask's design allows for a novel handgrip technique that allows a single healthcare provider to ventilate with enhanced sealing.

Cette invention se rapporte à un masque respiratoire qui assure une meilleure étanchéité grâce à l'utilisation d'un embout intrabuccal à large surface d'étanchéité. Un prolongement tubulaire, formé à une extrémité de façon à recevoir les embouts respiratoires standards, constitue le conduit d'amenée de l'air jusqu'à l'embout intrabuccal. Ce masque respiratoire peut également comprendre un passage d'air oropharyngé intrabuccal qui fléchit de façon à pouvoir être inséré sans qu'il soit nécessaire d'effectuer une rotation ou d'utiliser une lame abaisse-langue. Ce masque respiratoire peut également comporter un écran externe qui améliore l'étanchéité et forme une barrière de protection pour le personnel soignant. La conception de ce masque applique une nouvelle technique de prise manuelle qui permet à une seule personne soignante d'effectuer une ventilation avec une meilleure étanchéité.
