The STERRAD VELOCITY Biological Indicator (BI) /Process Challenge Device (PCD) is a selfcontained biological indicator, used in conjunction with the STERRAD VELOCITY Reader, that is intended for frequent monitoring and periodic testing of the STERRAD Sterilization Cycles, using rapid readout technology that provides a final fluorescence result in 15 minutes at the incubation temperature of 57 ± 2ºC. The STERRAD VELOCITY BI/PCD can also be determined as growth-positive or growth-negative via an optional visual pH-based color change result (using bromocresol purple) if used for frequent monitoring purposes. When using this method, the biological indicator must be cultured in an incubator at 55-60°C for 5 to 7 days to get a final visual result. The STERRAD VELOCITY BI/PCD consists of a glass fiber disc containing a minimum of 1 x 100 Geobacillus stearothermophilus (ATCC 7953) spores and a glass ampoule containing nutrient growth medium and non-fluorescent substrate, as well as a vial, cap, cap label, insert, and chemical indicator. The spore disc, growth media ampoule, and insert are contained in a clear plastic vial with a vented cap. The cap is designed with sterilant ingress openings which allow for penetration of hydrogen peroxide vapor into the vial during the sterilization process. The chemical indicator (CI), placed on the top of the cap, is a Type 1 process indicator that changes color from red/pink to yellow with some red/orange/brown dots when exposed to hydrogen peroxide. The STERRAD VELOCITY BI/PCD has the same a-glucosidase enzyme system for the fundamental scientific technology as the predicate device cleared under K182404. The a-glucosidase enzyme, which is generated naturally during growth of G. stearothermophilus and released during spore germination, hydrolyzes the bond between the glucose and 4-methylumbelliferyl (4-MU) moieties of 4methylumbelliferyl a-D-glucopyranoside (α-MUG). In the combined state, α-MUG is not fluorescent. Once the bond between the glucose and 4-MU is hydrolyzed, the 4-MU component becomes fluorescent when excited with UV light. Therefore, the a-glucosidase enzyme in its active state can be detected by measuring the fluorescence produced by the enzymatic hydrolysis of a-MUG. The resultant fluorescent by-product (4-MU), is detected by the Reader and the fluorescent signal is used to determine the positive or negative result of the biological indicator. The measured enzyme activity is reduced upon exposure to hydrogen peroxide. As the enzyme activity is directly correlated with the spore outgrowth, the reduction of the enzyme activity below a certain level indicates that all spores have been inactivated. The level of the fluorescence response is determined using the algorithm developed for the STERRAD VELOCITY BI/PCD and is used to distinguish between the positive and negative responses. The STERRAD VELOCITY Reader is designed to automatically read the STERRAD VELOCITY BI/PCD to obtain the final fluorescence result in 15 minutes at the incubation temperature of 57 ± 2℃. The STERRAD VELOCITY Reader utilizes the fluorometric assay method to detect the enzyme activity from the BI and the fluorescence emitted from the BI is converted into a voltage. This voltage reading is then used by the fluorescence algorithm in the Reader to determine the final fluorescence result. There are eight individual BI incubation wells in the STERRAD VELOCITY Reader. Its heater system is designed to maintain the biological indicators at 57 ± 2℃ to promote the outgrowth of the indicator organisms. Each well contains an ultraviolet light source that excites fluorescence in the growth medium, and a photodetector to detect that fluorescence. The STERRAD VELOCITY Reader features a touch screen for an effective user interface. Directly under each well is a well number illuminated by a well status indicator light. Three colors (white, green, and red) and two states (off and solid line) are used for the indicator light on the touch screen to show the status of the BI processing. The Reader has a thermoplastic exterior which makes it easy to clean and maintain. A built-in barcode scanner coupled with network connectivity makes maintaining sterilization records easy. The STERRAD VELOCITY Reader of the subject device has the same hardware and uses same fundamental scientific technology as the predicate device cleared under K182404. Only the algorithm for fluorescence reading has been modified in the subject device to reduce the fluorescence readout time from 30 minutes to 15 minutes.

The ASP AEROFLEX™ Automatic Endoscope Reprocessor (AER) with AUTOSURE™ MRC Monitor is indicated for use with high-level disinfectant ASP AERO OPA™ ortho-Phthalaldehyde Solution to achieve high-level disinfection of flexible semi-critical endoscopes. Manual cleaning of endoscopes is required prior to placement in the AER.

The AEROFLEX Automatic Endoscope Reprocessor (AER) with AUTOSURE MRC Monitor is designed to provide high-level disinfection for flexible, submersible endoscopes that have been manually cleaned. The AEROFLEX system consists of the software-driven AER, the AUTOSURE MRC reagent, AERO-OPA™ disinfectant solution, and AEROZYME™ enzymatic detergent. The AEROFLEX AER with AUTOSURE MRC Monitor is indicated for use with high-level disinfectant ASP AERO-OPA ortho-Phthalaldehyde Solution to achieve high-level disintection of semi-critical endoscopes; high-level disinfection requires that the AER be used with the AERO-OPA Solution per its Instructions for Use. Manual cleaning of endoscopes is required prior to placement in the AEROFLEX AER. After an endoscope is manually cleaned according to its manufacturer's recommended procedures, it is loaded into the AER. After starting the reprocessing cycle, the AER displays its progress during the cycle and signals that the cycle is complete on the control panel and with an audible tone. The minimum recommended concentration (MRC) of ASP AERO-OPA ortho-Phthalaldehyde Solution is automatically checked and verified by the AER for every cycle using an integrated MRC monitor and reagent. The MRC monitor- tests the OPA concentration in every high-level disinfection cycle without the use of test strips; if the OPA concentration is below the MRC the system cancels the cycle and notifies the user. To reduce user error and facilitate assurance of disinfection efficacy, the AEROFLEX System uses Radio Frequency Identification (RFID) technology to identify the ASP-branded consumables that are used with the system. Additionally, to enable electronic record-keeping by hospitals, the AEROFLEX system can be configured by users to transmit cycle printout information and/or print cycle records from the facility's network; the AEROFLEX System will also be compatible with ASP ACCESS™ Technology to allow automated record keeping.
