Intended Use

SteriChek™ Peroxide Reagent Strips provide a convenient means for measuring the concentration of peroxide remaining in water being used to rinse out dialysate lines and dialyzers following disinfection with peroxide/peracetic acid. The chemically treated pad changes color relative to the amount of peroxide remaining in the rinse.

Device Story

Device consists of 0.20 sq inch reagent pad on 3.25 inch opaque polystyrene strip. Pad contains 4-aminoantipyrine (4AAP), 8-amino-2-naphthalene sulfonic acid (ANS), peroxidase, and pH buffer. Input is rinse water from dialysate lines/dialyzers. Peroxidase catalyzes reaction between peroxide and indicators, producing red-purple color proportional to peroxide concentration. User compares pad color to calibrated label blocks (0-10 ppm). Used as rapid screen (<1.0 ppm) or quantitative estimate. Benefits patient by ensuring removal of residual peroxide post-disinfection.

Clinical Evidence

No clinical data. Bench testing only; performance verified by comparing reagent pad color development to calibrated color blocks representing known peroxide concentrations.

Technological Characteristics

Polystyrene strip with chemically treated reagent pad. Indicator system: 4-aminoantipyrine (4AAP) and 8-amino-2-naphthalene sulfonic acid (ANS) with peroxidase and pH buffer. Colorimetric detection method. Dimensions: 3.25 inch x 0.20 inch strip; 0.20 sq inch pad.

Indications for Use

Indicated for measuring residual peroxide concentration in rinse water for dialysate lines and dialyzers post-disinfection with peroxide/peracetic acid.

Regulatory Classification

Identification

A hemodialysis system and accessories is a device that is used as an artificial kidney system for the treatment of patients with renal failure or toxemic conditions and that consists of an extracorporeal blood system, a conventional dialyzer, a dialysate delivery system, and accessories. Blood from a patient flows through the tubing of the extracorporeal blood system and accessories to the blood compartment of the dialyzer, then returns through further tubing of the extracorporeal blood system to the patient. The dialyzer has two compartments that are separated by a semipermeable membrane. While the blood is in the blood compartment, undesirable substances in the blood pass through the semipermeable membrane into the dialysate in the dialysate compartment. The dialysate delivery system controls and monitors the dialysate circulating through the dialysate compartment of the dialyzer.(1) The extracorporeal blood system and accessories consists of tubing, pumps, pressure monitors, air foam or bubble detectors, and alarms to keep blood moving safely from the blood access device and accessories for hemodialysis (§ 876.5540) to the blood compartment of the dialyzer and back to the patient. (2) The conventional dialyzer allows a transfer of water and solutes between the blood and the dialysate through the semipermeable membrane. The semipermeable membrane of the conventional dialyzer has a sufficiently low permeability to water that an ultrafiltration controller is not required to prevent excessive loss of water from the patient's blood. This conventional dialyzer does not include hemodialyzers with the disposable inserts (Kiil type) (§ 876.5830) or dialyzers of high permeability (§ 876.5860). (3) The dialysate delivery system consists of mechanisms that monitor and control the temperature, conductivity, flow rate, and pressure of the dialysate and circulates dialysate through the dialysate compartment of the dialyzer. The dialysate delivery system includes the dialysate concentrate for hemodialysis (liquid or powder) and alarms to indicate abnormal dialysate conditions. This dialysate delivery system does not include the sorbent regenerated dialysate delivery system for hemodialysis (§ 876.5600), the dialysate delivery system of the peritoneal dialysis system and accessories (§ 876.5630), or the controlled dialysate delivery system of the high permeability hemodialysis system § 876.5860). (4) Remote accessories to the hemodialysis system include the unpowered dialysis chair without a scale, the powered dialysis chair without a scale, the dialyzer holder set, dialysis tie gun and ties, and hemodialysis start/stop tray.

The concentration of peroxide in rinse water is obtained by comparing Technological the color of the reagent pad with color blocks on the label. The color Characteristics: blocks are calibrated in terms of peroxide concentration in parts per million (ppm). The device is used as a rapid screening method to detect levels of less than 1.0 ppm, or as a quantitative method to allow estimation of peroxide concentration between 0 and 10 ppm.

> SteriChek™ Peroxide Reagent Strips contain 4-Residual aminoantipyrine (4AAP) and 8-amino-2-naphthalene sulfonic acid (ANS), two colorless compounds which serve as the indicator system, peroxidase and a pH buffer. The reaction of the indicator reagents with hydrogen peroxide is catalyzed by peroxidase. This reaction of the indicators gives rise to a red-purple color. The intensity of the color is proportional to the concentration of the peroxide.

Assessment of The predicate device has been manufactured by Environmental Test Systems, Inc. since its introduction by Serim Research Corporation. Performance: ETS will manufacture the SteriChek™ Residual Peroxide Reagent 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 follows the same test principles as the predicate device.

The SteriChek™ Residual Peroxide Reagent Strips have the same Conclusion: 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 the change of indicators and the trade or proprietary name of the device. The SteriChek™ Residual Peroxide Reagent Strips have no technological characteristics that raise new types of safety or effectiveness questions.
