Warm moist respiration gases provision device - uses heating elements associated with atomisation chamber allowing thermal disinfection using raised temp. maintained for timed interval

摘要

The respiration gases provision device uses an atomisation chamber (40) incorporating heating devices (52, 60) for the water and a spray jet (56) supplied with pressurised air. The heating devices (52, 60) allow thermal disinfection of the atomisation chamber (40) by heating to a temp. of about 125 degrees C. The obtained temp. is maintained for a time interval of variable duration. Pref. the atomisation chamber (40) has an inlet (68) and outlet (70) above the water level on opposite sides. The inlet (68) is preceded by a gas pre-heating chamber (32) with a further heating device (34) and a pressurised air and oxygen connection. The respiration line (74) feeding the air mixture to the patient is coupled to the outlet (70). ADVANTAGE - Simple, effective disinfection of atomisation chamber.
