Artificial respiration device for patient suffering from e.g. cardiac arrest, has pressure drop element assuring that utilization pressure of gas is equal to higher value of utilization value range when supply pressure has maximum value

摘要

The device has a tubular shell (5) for forming a main inner canal (7) and connected by its distal end to airway of a patient. The shell has a proximal end (5P) arranged outside the patient. Deflection units are placed inside the canal for converging respiratory gas jets (J) that are injected by auxiliary channels. A respiratory gas supplying conduit (12) has a specific pressure drop element constituted by a stopper (13) assuring that utilization pressure of respiratory gas is equal to a higher value of range of utilization values, when supply pressure of the gas has a maximum value.
