A system, comprising a tube (4) forming a main gas channel (5) connected by its distal end (3) to the patient's airway and an auxiliary channel (8) for an inhaled gas, incorporates at least one inner duct (21), some 200 - 300 microns in diameter, to deliver a liquid to be nebulised. A system, comprising a tube (4) forming a main gas channel (5) connected by its distal end (3) to the patient's airway and an auxiliary channel (8) for an inhaled gas, incorporates at least one inner duct (21), some 200 - 300 microns in diameter, to deliver a liquid to be nebulised. The duct enters the main channel through the tube's proximal end and has an oblique outlet (23) close to that of the auxiliary channel (8). Outside the tube (4) the duct has a section (24) that rises approximately vertically. |
