ABSTRACT:
Method and apparatus are provided for ultrasonic cleaning and decontaminating, disinfecting, or sterilizing articles, such as surgical instruments, in a single piece of equipment. Energy transmission through a unitized shell wall coupled with deep vacuum conditions in the chamber enables rapid degasification, enhanced cavitation providing effective and efficient ultrasonic cleaning in a sealed vessel capable of carrying out high pressure sterilization.
Sonic energy transducers are rigidly mounted externally of the unitized shell to achieve desired cavitation substantially uniformly throughout the volume of the chamber established for placement of articles to be ultrasonically washed and biocidally treated.
