ABSTRACT:
A method and apparatus assures effective operation of sterilizers, especially those of the pre-vacuum type. The apparatus performs two principal methods: (1) testing for completeness of air removal from a sterilizer chamber, including the re-entrainment of air in the load due to air leaks in the chamber, vacuum system and/or steam system, and (2) the testing for effective sterilization conditions. Also, performed are three secondary methods: (i) identifying of causes of sterilizer faults, (ii) providing of preventive maintenance procedures (an Early Warning) (iii) identifying of procedures to correct sterilization faults in progress. These methods are illustrated for the two principal modes of operation: (a) the performance of a Bowie and Dick type test, as is usually done on a once-a-day basis; and (b) monitoring the sterilizer during load conditions.
