Patent ID: 8312882

Claim:
An artificial respiration device comprising: a tubular element having a proximal end and a distal end, which forms a main channel having an upstream part at the proximal end of the tubular element and a downstream part at the distal end of the tubular element, in which the distal end of the tubular element is configured to connect to an airway of a patient and the proximal end of said tubular element is located outside said patient and the patient's respiratory system is connected to the outside by way of said main channel; auxiliary channels, which are supplied with respiratory gas, and which open into said main channel; and deflecting means internal to said main channel configured to deflect jets of respiratory gas injected into said main channel via said auxiliary channels to converge at a point of convergence inside said main channel, wherein said tubular element comprises at least one lateral safety orifice, which extends through a lateral wall of the tubular element at a location substantially opposite the point of convergence inside the main channel and configured to communicate air from outside the tubular element to the downstream part of said main channel and downstream of said deflecting means.
