Sterilization
Chemical Solution Sterilization
After finishing the cleaning, select an effective sterilant for chemical solution sterilization of the
operating room equipment. Buffered glutaraldehyde (e.g. Cidex or Hospisept) is recommended.
Do not use quaternary cationic detergents such as zephiran chloride. If the whole unit is to be
sterilized, immerse the transducer but not the electrical connector into the sterilant for the
recommended sterilizing period. Ensure that the dome has been removed. Then rinse all
transducer parts except the electrical connector with sterilized water or saline. The transducer
must be thoroughly dried before storing.
Gas Sterilization
For more complete asepsis, use gas sterilization. The transducer should be completely dry after
cleaning. When ethylene oxide gas is used as the gas disinfectant, follow the operating
instructions provided by the manufacturer of the gas disinfectant.
NOTE
z The disinfectant temperature must not exceed 70°C (158°F). Plastics in the
pressure transducer may deform or melt above this temperature.
