Automatic sterilizing autoclave
Abstract
Abstract AN AUTOCLAVE FOR STERILIZING ARTICLES BY STEAM UNDER PRESSURE WITH FULLY AUTOMATIC OPERATION THROUGHOUT A STERILIZING CYCLE. AN AUTOMATICALLY CONTROLLED VALVE IN THE AIR-STREAM EXHAUST PASSAGEWAY FROM THE AUTOCLAVE PRESSURE CHAMBER CLOSES THE EXHAUST PASSAGEWAY ONLY AT A PRESELECTED TEMPERATURE IN ORDER TO FIRST EXHAUST AIR FROM THE PRESSURE CHAMBER AT THE BEGINNING OF THE STERILIZING CYCLE, AND OPENS THE EXHAUST PASSAGEWAY AFTER A PREDETERMINED PERIOD AT THE END OF THE STERILIZING CYCLE, AT WHICH TIME THE HEATING ELEMENT IS ALSO AUTOMATICALLY CUT OFF. DURING THE STERILIZING CYCLE, NON-STERILE POCKETS OF AIR IN THE PRESSURE CHAMBER ARE AUTOMATICALLY PURGED THROUGH THE AIR-STREAM EXHAUST PASSAGEWAY BY THE AUTOMATIC CONTROL VALVE.
