Un côté du tuyau d'alimentation en oxygène comprend un tuyau de raccordement oral qui est configuré pour être en contact étroit avec les voies respiratoires du patient, et l'autre côté, qui a des conduits branchés, est branché dans un premier orifice d'embranchement menant à un tuyau d'expiration équipé d'un clapet d'expiration, et un second orifice d'embranchement menant à un tuyau de raccordement de sac gonflable, la soupape de commande pour le conduit d'inspiration et d'expiration d'air étant disposée à la position à laquelle le premier orifice d'embranchement et le second orifice d'embranchement sont branchés. Pendant l'inspiration d'air, la soupape de commande pour le conduit d'inspiration et d'expiration d'air ouvre le second orifice d'embranchement et ferme le premier orifice d'embranchement à l'aide d'une pression provenant de l'oxygène provoquée par la compression du sac gonflable. La soupape inférieure du sac gonflable, qui est raccordée à un tuyau de raccordement de récipient d'oxygène, est agencée à une partie d'extrémité à l'intérieur du sac gonflable. Pendant l'inspiration d'air, la soupape inférieure du sac gonflable est fermée par la pression de l'oxygène provoquée par la compression du sac gonflable de telle sorte que l'oxygène à l'intérieur du sac gonflable est évacué vers le tuyau d'alimentation en oxygène.
