23 5 DEVICE OPERATION Programming Times Programming Times associated with MEDIVATORS SCOPE BUDDY Endoscope Flushing Aid are dependent on the associated endoscope and the applicable step in the reprocessing workflow. Always verify correct programming times comply with endoscope manufacturers guidelines prior to use. For manual precleaning, programming times should be determined based on endoscope manufacturer recommendations for flushing volumes. For manual High-Level Disinfection, programming times should be determined based on contact time needed for the HLD solution. Flushing Times for Manual Cleaning Published programming times are intended for use during the flushing of detergent and rinse water through endoscope channels as part of the manual precleaning process only. Programming times listed in the provided SCOPE BUDDY Flushing Aid Rinse Matrix are applicable for OLYMPUS, PENTAX, and FUJINON brand endoscopes used with SCOPE BUDDY Flushing Aid units having a serial number > The SCOPE BUDDY Flushing Aid Rinse Matrix for Manual Cleaning can be found by logging onto the MEDIVATORS website located at and navigating to the SCOPE BUDDY Endoscope Flushing Aid page located in subchapters Endoscope Reprocessing/Pre-cleaning. Always verify the correct SCOPE BUDDY Flushing Aid Rinse Matrix is being used for the serial number of the flushing aid in use. The SCOPE BUDDY Flushing Aid Rinse Matrix times for Manual Cleaning are based on in-house validation tests that were conducted using endoscopes with channels in good working condition, free from restrictions and absent of any defects. These rinse times represent the groupings of all like-model endoscopes in terms of channel configuration. Recommended programming times reflect the worst case flushing time in each endoscope grouping. Rinse times may be reduced by individual flow testing of a specific endoscope. Always ensure flushing volumes comply with endoscope manufacturers guidelines. Times stated in the SCOPE BUDDY Flushing Aid Rinse Matrix assume that the connection tubing and hookup kits from SCOPE BUDDY Flushing Aid to the endoscope are primed and full of fluid. Programming times should be extended by 10 seconds if the tubes are not pre-primed. Due to differences in individual endoscope channel performance, users should always verify that the solution volumes meet the manual cleaning requirements of the endoscope manufacturer and/or the facility. Users are encouraged to validate endoscope specific flushing times based on their individual models of endoscopes. The recommended method of checking the flushing times required for a specific endoscopes is to separate the flow of fluid exiting from each channel at the distal end while SCOPE BUDDY Flushing Aid is flushing. Using a small plastic card to help isolate the flow from each channel being checked, direct the individual channel flow into a measuring beaker and record the time it takes to flush the required amount of fluid through each channel. The flushing time required for SCOPE BUDDY Flushing Aid should reflect the time it took for the slowest channel to flow the required volume of fluid. This is usually the air/water channel SCOPE BUDDY Flushing Aid has been designed to be compatible with all flexible endoscopes irrespective of manufacturer. A default flushing time of 2 minutes 30 seconds can be used to ensure delivery of 100 mls of solution through each channel of the majority of endoscopes regardless of manufacturer or endoscope model. Users can validate shorter flushing times following the process above. 19

24 Flushing Times for Manual High-Level Disinfection During Manual High-Level Disinfection SCOPE BUDDY Flushing Aid Programming Times should be set to correspond with the contact time required for High-Level disinfectant being used. Programming times should be extended by 10 seconds if the tubes are not pre-primed with HLD solution. NOTE: Only approved room temperature aldehyde-based high-level disinfectants can be used with SCOPE BUDDY Flushing Aid. NOTE: Do not use chemistries that contain bleach, hydrogen peroxide or alcohol in SCOPE BUDDY Flushing Aid. NOTE: SCOPE BUDDY Endoscope Flushing Aid does not replace an Automated Endoscope Reprocessor (AER). Use During Manual Cleaning SCOPE BUDDY Endoscope Flushing Aid is approved for use in recirculating detergent, high-level disinfectant, and rinse water solutions through endoscope channels. The following instruction should be followed for successful manual cleaning and high-level disinfection of endoscopes NOTE: The endoscope leak test must be performed prior to immersing the endoscope in fluid according to manufacturer s guidelines. NOTE: Endoscope channels should be brushed in accordance with manufacturer s instructions prior to connection to SCOPE BUDDY Flushing Aid. NOTE: Detergent and Rinse Water cleaning solutions can be drawn from either a clean container for a single-pass through SCOPE BUDDY Flushing Aid, or recirculated from the sink through SCOPE BUDDY Flushing Aid. SCOPE BUDDY Flushing Aid can be used in either format depending on the facility s endoscope cleaning procedure.

Daily Quality Assurance Test Items needed: Fluid Intake Tubing (L-1) SCOPE BUDDY Flushing Aid Universal Cleaning Adapter Extension Line (L-3) Flow Verification Tube (QA-1) Graduated Cylinder (QA-2) To verify SCOPE BUDDY Flushing Aid is operating properly and delivering the correct amount of fluid, the Quality Assurance Flow Validation Test must be performed. This validation test should be performed prior to the first use of the day and quickly determines if the device is delivering the correct volume of fluid. The SCOPE BUDDY Flushing Aid validation test is performed using the Flow Verification Tube, Fluid Intake Line, the Universal Cleaning Adapter Extension Line, the SCOPE BUDDY Flushing Aid, and a graduated cylinder. To perform the test, SCOPE BUDDY Flushing Aid is preset to pump for a specific period of time and then after flushing, the dispensed fluid is measured to identify if it is within an acceptable volume range. Although the test can be performed at any time, it is recommended that it be run at the start of each work day. Use the following procedure to perform the test. WARNING: Failure to perform the daily quality test can result in the device not delivering the proper amount of fluid through the channels of an endoscope. NOTE: A 200cc graduated cylinder is required to perform this test. Flow Validation Setup and Tubing Prime: 1.
