ABSTRACT:
Device for respiratory assistance, comprising a tube (4) which forms a main channel (5) and which is intended to be connected via its distal end (3) to the respiratory tract of a patient so that said main channel (5) connects the respiratory system of said patient to the outside, with said device moreover comprising at least one auxiliary channel (8) formed in the wall of said tube (4) and permitting the insufflation of a respirable gaseous jet into said respiratory system and opening into said main channel (5) in the vicinity of the distal end (7) of the latter.
According to the invention, this device is distinguished by the fact that it comprises a controlled valve (21) capable of closing at least partially the proximal end of said main channel (5), at least during insufflation of said gaseous jet.
