Ultrasonics technology has been long recognized as a highly effective cleaning method in healthcare and non-medical fields. Since 1979 CU has safely utilized low intensity sound waves with flexible endoscopes to set into very rapid motion the molecules of water and detergent and create bubbles. When these microscopic bubbles reach critical mass, they implode and create a vacuum that removes contaminants from endoscope surfaces including crevices which may not be readily accessible or areas containing obscure debris.

What’s the advantage of a channel monitoring feature in an AER?

Channel monitoring capabilities utilize sensors that will detect flow through the System 83 Plus purging manifold fluid paths, each adapter and their associated components.

How do I know which adapters are required to reprocess my flexible endoscopes?

Channel connectivity for all scopes in inventory should be reviewed during the initial System 83 Plus in-service. To confirm the recommended channel adapters for a particular brand and model instrument, please refer to the Scope Adaptation Charts such as those available at www.customultrasonics.com. Scope Connection Diagrams are also available illustrating the appropriate connection of channel adapters. Whenever in doubt, always check with Custom Ultrasonics to confirm the correct connections between endoscope and AER. (Contact Custom Ultrasonics when a new scope is purchased).

Does Custom ULtrasonics recommend any particular detergent for cleaning endoscopes during the wash cycle in System 83 Plus?

Custom Ultrasonics recommends the use of Tergal 800 alkaline detergent because this specific solution has been tested and its cleaning performance validated in System 83 Plus. Detergents other than Tergal 800 may be used provided (1) they are specifically formulated for ultrasonic cleaning, (2) they are compatible with the components of the endoscope and System 83 Plus.

Are the endoscopes completely submersed in both detergent and disinfectant during the wash and high-level disinfection cycles?

Yes, in each stage including cleaning, disinfection and rinsing all portions of the endoscope are completely submersed and fully exposed to reprocessing solutions. Additionally, during all cycles solution is flushed through all endoscope channels.

Why do so many channel adapters have to be connected to the Custom Ultrasonics AER?

Unlike some other products which utilize bifurcated or multi-branched adapter tubes, Custom Ultrasonics has always been a proponent of one-on-one channel adapters to ensure optimum flow to each/every channel. Without such individualized channel connections, fluid will take the path of least resistance and flow primarily through the larger sized channels.

Why is it that Custom Ultrasoncis AERs have no automated leak test feature?

Custom Ultrasonics believes that automated leak testing found in AERs have inherent limitations and shortcomings. First, such automated testing does not allow instruments to be tested consistent with endoscope OEM instructions calling for deflection of the distal bending section. Without such flexing and stretching of the distal sheath, tiny “pinhole” leaks may not be detected. Secondly, instructions from these same AERs state that automated leak testing is not a replacement for manual leak testing per OEM recommendations (and manual leak testing should still be performed). Thirdly, the sealed leakage tester connector used in AERs prevents contact of germicide with potentially contaminated surfaces of the scope venting/leak test connector – so, if this connector is contaminated before automated reprocessing, it will remain contaminated.

Can TEE probes be reprocessed in the System 83 Plus Washer/Disinfector?

No, the indications for use for the System 83 Plus Washer/Disinfector state that the System 83 Plus Washer/Disinfector is designed for the simultaneous reprocessing of flexible, submersible endoscopes. The TEE probe is not considered to be an endoscope and therefore, should not be reprocessed in the System 83 Plus Washer/Disinfector.

What’s the benefit of a Custom Ultrasonics scope storage cabinet?

The Model 20000 Endoscope Storage Cabinet is designed to store up to eight flexible endoscopes.  Safety, performance and dependability have been given top priority in the design of this product making it easy to maintain and operate.  The endoscope storage cabinet safely and securely stores your endoscopes when they are not in use.

Can miscellaneous items be reprocessed in the disinfectant reservoir?

NO! Do not place any items to be disinfected in the chemical reservoir. And, do not attempt to reprocess water bottles, syringes, sponges, containers, etc. along with the endoscope in the processing chamber.

How would a Custom Ultrasonics Pre-Processing Sink help my cleaning staff?

The Custom Ultrasonics 83-S6 / 83-S8 Pre-Processing sink is designed to aid in and simplify the performance of manually pre-processing lumened Instruments. The sink is of a size to provide sufficient space to accommodate virtually all instruments and accessories that require manual pre-processing.

 
Why is ultrasonic cleaning so important?

Ultrasonics technology has been long recognized as an effective cleaning method in healthcare and non-medical fields. Since 1979 Custom Ultrasonics has safely utilized ultrasonics with flexible endoscopes to set into very rapid motion the molecules of water and detergent and create bubbles. When these microscopic bubbles reach critical mass, they implode and create a vacuum that removes contaminants from endoscope surfaces including crevices which may not be readily accessible or areas containing obscure debris. This cavitation process dislodges soil from contaminated surfaces and crevices.

Why does Custom Ultrasonics' AERs have high-pressure ports?

High-pressure ports ensure that there is consistent and adequate flow of reprocessing fluids into extremely narrow lumens, longer-length channels and/or lumens with restricted space. Traditionally, elevator-wire channels have been recognized as being most difficult to reprocess due to the additional pressures required to generate sufficient fluid flow through such a channel most of whose volume is occupied by a multi-stranded control wire and long length water jet channels.

 

Does Custom Ultrasonics have microbiological validation data to support its reprocessing claims?

Yes, to support its 510K submission for System 83 Plus Custom Ultrasonics sponsored independent laboratories to perform microbiological simulated-use studies using worst case scenarios. Using a patented site specific test protocol data demonstrating effective cleaning and high-level disinfection was obtained for individual channels, external scope surfaces as well as instrument components (ex. valves). As more complex instruments have been developed, CU has performed additional microbiological studies supporting its reprocessing claims under worst-case conditions for these more challenging multi-channeled flexible endoscopes (certain ultrasound scopes) which have more than 5 internal channels, including an exposed elevator wire channel.
