The evaluation of surgical instrument washers using en enzyme detergent lubricant cleaner confirmed that the efficacy of disinfection was 100%. All surgical instruments and utensils tested were sterile at the completion of the process.
Summary : Properly Designed Washer Decontaminators Washer Disinfectors are designed to clean all surfaces thoroughly, thereby providing the critical prerequisite for the safe handling, and to disinfect, and the sterilize surgical instruments. Critical cleaners, usually referred to as Washer Decontaminators Washer Disinfectors, perform pre-wash, ultrasonic (optional), detergent washing, purified water elevated temperature rinsing, lubrication and high temperature drying in such a manner as to provide thoroughly clean, stain free and lubricated medical devices. Surgical Instruments cannot be sterilized (be sterile) unless all exposed surfaces are properly cleaned, prior to sterilization, to remove soil (debris, bioburden) and properly rinsed to prevent staining. Not all Washer Decontaminators Washer Disinfectors provide adequate pre-rinsing, pre-cleaning, purified water rinsing, and thereby render higher rejection rates of processed surgical instruments. The proper sequence of treatment and the correct choice of time, temperature and the components used are necessary to render surgical instruments that are critically clean, safe to handle, and have the prerequisite for sterilization. Washer Decontaminators Washer Disinfectors employ a cold water pre-wash to remove gross debris. This removes proteins and lipids, preventing them from being baked onto devices during the high temperature treatments to follow. Then, the ultrasonic process creates millions of micro implosions to loosen and free debris from lock boxes, hinge pins, serrations and other difficult-to-access surface areas.
The Washer Decontaminators Washer Disinfectors detergent wash then applies high flow low pressure water with a cleaning concentrate (at ~ 135 degrees F) in such a manner as to evenly reach all areas of the load and strip bioburden from the surgical instruments. The elevated temperature (at ~ 194 to 209 degrees F) purified water final rinse secures the biocidal process, removes mineral deposits from prior cycles and lubricates the instruments. The high temperature (at ~ 158 to 230 degrees F) dry cycle presents heated, forced air which dries each device. The critical cleaned medical devices are now clean, safe to handle, have the prerequisite for sterilization, and are properly prepared for further reprocessing.
