The invention relates to an apparatus (1) for administering a gas to a person or an animal, provided with a chamber (9) for receiving a quantity of gas to be administered, which chamber is provided with a gas line (3) for supplying gas from a source to the chamber (9) and means for pressurising the gas in the chamber (9), the chamber (9) connecting to a breathing tube (5) for supplying pressurised gas from the chamber (9) to the person or the animal, wherein the breathing tube (5) connects to a discharge channel (26), for discharging gas exhaled by the person or the animal, via a valve (11), which valve (11) restricts the flow of the exhaled gas from the breathing tube (5) to the discharge channel (26) in order to build up gas pressure in the breathing tube (5) during exhalation.

L'invention concerne un dispositif (1) permettant d'administrer un gaz à une personne ou à un animal. Ce dispositif comprend une chambre (9) destinée à recevoir une dose de gaz à administrer. Cette chambre comprend un conduit (3) de gaz permettant d'acheminer le gaz jusque dans la chambre (9) à partir d'une source, et des moyens permettant de pressuriser le gaz contenu dans la chambre. La chambre (9) communique avec un tube (5) respiratoire permettant l'administration du gaz pressurisé contenu dans la chambre (9) à une personne ou à un animal. Ce tube (5) respiratoire communique par l'intermédiaire d'une soupape (11) avec un canal (26) d'évacuation qui évacue le gaz exhalé par la personne ou l'animal. Cette soupape (11) limite le passage de gaz exhalé entre tube (5) respiratoire, et le canal (26) d'évacuation de manière à augmenter la pression du gaz dans le tube (5) respiratoire pendant l'exhalation.
