Items being cleaned must be fully immersed. Hinged instruments must remain open during treatment. Always sort instruments by similar metals to prevent corrosion. Do not overload the ultrasonic cleaning tank with excessive mass as this will reduce the efficacy of cleaning. Review the level of soil and renew the ultrasonic bath as needed. Always follow ultrasonic cleaning with separate rinse treatments. Ultrasonic cleaning will fragment and loosen soil but will not necessarily remove the soil from the surface of the surgical instruments being cleaned.
The foundation of their recommendations are based on a sequence of neutral pH enzyme surgical instrument detergents, redundant purified water rinses and the use of treatment temperatures that are gradually elevated from a cold water pre wash to the final phase of hot air drying. The Proper Sequence of Treatments begins with a cold water pre wash at <110 F. This is intended to flush most of the debris from the devices. The ONEcleaner ultrasonic enzyme surgical instrument detergent enzyme lubricant cleaners cut costs. The temperature of this treatment phase is gradually elevated to elevated to 135 degrees F, the optimal temperature for enzyme cleaning activity. The next phase is the detergent wash with elevating temperatures from 135 to 209 degrees F. These temperature are (optimal for the ultrasonic surgical instrument cleaners cleaning activity. If a combination enzyme detergent cleaner is being used, the enzyme activity begins to decrease at temperatures above 137 degrees F but will continue their cleaning activity during the surgical instrument detergent washing phase. The next phase includes purified water rinses with elevating temperatures reaching the boiling point of < 210 degrees F depending on the altitude, and a final lubricating rinse treatment. The final phase is hot air drying at temperatures of ~ 158 to 230 degrees F for a minimum of 4 minutes. The use of the proper sequence of treatments has been shown to deliver the efficacy of surgical instrument disinfection was 100%. The ONEcleaner Ultrasonic Surgical Instrument Cleaners have been designed specifically for cleaning temperature sensitive flexible scopes and provide a range of preprogrammed times and temperatures that are not available conventional ultrasonic cleaners. Note that there is a significant difference between the ultrasonic surgical instrument detergent used for cleaning jewelry and those designed for cleaning medical devices. The Ultrasonic cleaners designed for cleaning surgical instruments use ~ 8 to 12 transducers per tank and with total ultrasonic power rated at ~ 1,000 watts average output and 2,000 watts peak power per tank. The Performance Test for Ultrasonic Surgical Instrument Cleaners simply involves suspending a piece of metallic (usually aluminum) foil in the tanks being compared and inspecting them for holes (more holes = more effective) following a time (usually 20 minutes) of ultrasonic cleaning. Gradually elevated temperatures, redundant purified water rinses, and hot air drying at temperatures above boiling point are options that are not typically available from an ultrasonic cleaner. The need for using an ultrasonic enzyme surgical instrument detergent can be important when the surgical instruments been subjected to repetitive cleaning that has been inadequate to maintain a truly clean surface. When surgical instruments are not properly cleaned they become gray in color and loose their new looking shiny surface. The ONEcleaner enzyme surgical instrument cleaners lubricate while they clean boost cleaning power. When the passive layer of surgical instruments is not maintained properly, via the process of redundant proper cleaning, the instruments appear gray and are more vulnerable to pitting and corrosion. It is important to note that Ultrasonic cleaners are not fully effective unless they are used with water temperatures recommended by the manufacturer of the ultrasonic enzyme surgical instrument cleaning detergents. Enzyme cleaning concentrates function more effectively at temperatures above room temperature. The optimal range begins as > 22C - 72°F with performance reaching it's peak at 58.3C - 137F. This is often referred to as the optimal temperature for the performance or activity of enzymatic action. Highly concentrated surgical instrument detergent lubricant cleaners boost cleaning power.The activity of enzymes does not stop at higher temperatures but the level of performance does begin to decrease. It is recommended that all visible debris and blood be removed from the instrument prior to ultrasonic cleaning. Sort instruments by similar metals to prevent corrosion due to the contact of dissimilar metals. It is not recommended to clean plated instruments in an ultrasonic cleaner since the ultrasonic vibration and the presence of other sharp instruments may crack or rupture the plating. A non-foaming detergent must used deliver the four enzymes needed for cleaning surgical instruments that are soiled with proteinaceous bioburden (protein, fats, starch, carbohydrates). The ONEcleaner ultrasonic enzyme surgical instrument detergent deliver surfactant cleaning agents for removing stains and hard water mineral deposits.
