Respiratory care apparatus of the type comprising a respiratory gas generator incorporating means for establishing, during an inspiratory phase in a supply conduit leading to an inspiratory orifice associated with an expiratory valve, a substantially constant pressure of a respiratory gas, regardless of the flow rate of the inspiratory gas, characterised in that the means for establishing a substantially constant pressure comprise an ejector 1 of the diffuser type 1 leading into the said supply conduit 5. In contrast to those ventilators with multiple ventilation modes, which apply generally to intubated or tracheotomized patients, the invention applies to patients who are connected to the apparatus by means of a simple mask surrounding the nose and the mouth, a nasal mask or a mouthpiece. <IMAGE> |
