Device Facts

• Record ID: K980164
• Device Name: STERICHEK PERACETIC ACID REAGENT STRIPS
• Applicant: Environmental Test Systems, Inc.
• Product Code: MSY · Gastroenterology, Urology
• Decision Date: Apr 16, 1998
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 876.5665
• Device Class: Class 2

Indications for Use

SteriChek Peracetic Acid Reagent Strips provide a convenient means for determining the effective levels of peracetic acid in dialyzer reprocessing. The chemically treated pad changes color relative to the amount of peracetic acid in the dialyzer reprocessing mix.

Device Story

Device consists of reagent-treated pad on polystyrene strip; used to detect peracetic acid concentration in dialyzer reprocessing solutions. User dips strip into solution; chemical reaction between peracetic acid, starch, potassium iodide, and pH buffer oxidizes iodide to iodine; forms gray/purple or black color indicating acceptable levels; absence of color indicates insufficient levels. Visual comparison of color change after 10 seconds allows clinician to verify reprocessing efficacy. Benefits patient by ensuring dialyzers are properly disinfected before reuse.

Clinical Evidence

Bench testing only.

Technological Characteristics

Reagent pad containing starch, potassium iodide, and pH buffer affixed to 3.25 x 0.20 inch white opaque polystyrene strip. Sensing principle: chemical oxidation-reduction reaction resulting in colorimetric change. Standalone, non-electronic, visual-read device.

Indications for Use

Indicated for determining effective peracetic acid levels during dialyzer reprocessing in hemodialysis settings.

Regulatory Classification

Identification

A water purification system for hemodialysis is a device that is intended for use with a hemodialysis system and that is intended to remove organic and inorganic substances and microbial contaminants from water used to dilute dialysate concentrate to form dialysate. This generic type of device may include a water softener, sediment filter, carbon filter, and water distillation system.

Special Controls

*Classification.* Class II (special controls). The device, when it is a water purification subsystem disinfectant, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.

## SteriChek Peracetic Acid Reagent Strips 510(k) Safety and Effectiveness Summary - January 15, 1998 Environmental Test Systems, Inc. (Page 2 of 2)

The concentration of peracetic acid in dialyzer reprocessing is obtained Technological Characteristics: by observing the absence or concentration of color. None or minimal color after 10 seconds indicates insufficient levels of peracetic acid and dark color (gray/purple) or black indicates acceptable levels of peracetic acid.

> SteriChek™ Peracetic Acid Reagent Strips contain starch, potassium iodide and a pH buffer. When reacted with peracetic acid, the iodide is oxidized to iodine, forming a gray/purple color with starch.

The predicate device has been manufactured by Environmental Test Assessment of Performance: Systems, Inc. since its introduction by Serim Research Corporation. ETS will manufacture the SteriChek™ Peracetic Acid Strips using the same manufacturing and quality assurance procedures to produce a product identical in performance to the marketed device, but with a new name. The change in formulation provides for different color development but follow the same test principles as the predicate device.

Conclusion: The SteriChek™ Peracetic Acid Reagent Strips have the same intended use as the predicate device. There will be no changes in the design, materials, or other features compared to the predicate device, other than a change in color development and the trade or proprietary name of the The SteriChek™ Peracetic Acid Reagent Strips have no device. technological characteristics that raise new types of safety or effectiveness questions.

Dear Mr. Piekarski:

We have reviewed your Section 510/k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalion assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register.
