Intended Use

The Reprocessing Products Corporation Test Strips are intended for use in the monitoring of pH in Dialysate and Water.
The Reprocessing Product Corporation (RPC) pH Test Strips are indicated for determining the pH of acid dialysates, bicarbonate dialysates, or water. These Test Strips are indicated for testing acid/bicarbonate dialysates and water.
pH Test Strips are comprised of two different pH ranges:
pH = 6.8-8.5 (K100-0117) is for acid/bicarbonate dialysate, bicarbonate concentrate and water
pH = 0-14 (K100-0104) is for water used to make up dialysate.

Device Description

Device is semi-quantitative, reagent test strip comprised of a pad impregnated with chemicals which change color upon contact with Dialysate or Water respectively. The pad is attached to a plastic strip for handling.

AI/ML Overview

Here's an analysis of the acceptance criteria and study information for the Reprocessing Products Corporation pH Test Strips, based on the provided text:

1. Acceptance Criteria and Reported Device Performance

The document does not explicitly state pre-defined acceptance criteria in terms of specific quantitative metrics like sensitivity or accuracy percentages. Instead, the performance is described qualitatively.

Acceptance Criteria (Implied)Reported Device Performance
Accurate pH determination (correlation to Hydrogen ion concentration)"The test strip contains a specialized chemical formulation that reacts with the Hydrogen ion concentration in solutions of dialysate and water. The reaction results in a color change which is correlatable to the concentration of Hydrogen ions in the solution."
Consistent and correct color changes across the specified pH ranges"The data confirm that the product consistently generates color changes which match the color blocks for the Reference solution pH. Reference solutions were used to evaluate pH performance between 6.8 and 8.5 in acid/bicarbonate dialysate, bicarbonate concentrate and water, and the pH performance between 0 and 14 in water used to prepare dialysate."
Appropriate performance for intended use (hemodialysis dialysate and water)"These data demonstrate appropriate performance for use in hemodialysis dialysate and water."

2. Sample Size Used for the Test Set and Data Provenance

  • Sample Size: The document does not specify a numerical sample size for the test set. It mentions "Reference solutions were used to evaluate pH performance." This implies a series of solutions at various pH levels within the specified ranges, but the exact number is not provided.
  • Data Provenance: The document does not explicitly state the country of origin. It can be inferred that the testing was conducted by the manufacturer, Reprocessing Products Corporation, based in Tucson, AZ, USA. The data appears to be prospective, as it describes the evaluation of the product's performance against reference solutions.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

The document does not mention the use of experts to establish ground truth for the test set. The ground truth appears to be established by the reference solutions themselves, whose pH values are presumably known through independent, calibrated means (e.g., pH meters).

4. Adjudication Method for the Test Set

No adjudication method is described or implied, as the ground truth is established by reference solutions and the device's color changes are matched against these.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No MRMC comparative effectiveness study is mentioned. This device is a test strip with a visual color change, not an AI-assisted diagnostic tool that would typically involve human readers interpreting images.

6. Standalone (Algorithm Only) Performance Study

Yes, a standalone performance study was done. The "Performance" section explicitly states: "The data confirm that the product consistently generates color changes which match the color blocks for the Reference solution pH." This refers to the device's inherent ability to produce accurate results independent of human interpretation or assistance, by visually matching the color to a provided chart.

7. Type of Ground Truth Used

The ground truth used was reference solutions with known pH values. The device's color changes were compared to the color blocks corresponding to these reference pH values.

8. Sample Size for the Training Set

The concept of a "training set" is not applicable here in the context of machine learning. This device is a chemical reagent test strip, not a machine learning algorithm. Its performance is based on chemical reactions, not trained data.

9. How the Ground Truth for the Training Set Was Established

As explained above, there is no "training set" in the machine learning sense for this type of device. The chemical formulation of the test strip is designed to react in a specific way to different pH levels, and its performance is evaluated against chemically prepared reference solutions.

§ 876.5820 Hemodialysis system and accessories.

(a)
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.
(b)
Classification. (1) Class II (performance standards) for hemodialysis systems and all accessories directly associated with the extracorporeal blood system and the dialysate delivery system.(2) Class I for other accessories of the hemodialysis system remote from the extracorporeal blood system and the dialysate delivery system, such as the unpowered dialysis chair, hemodialysis start/stop tray, dialyzer holder set, and dialysis tie gun and ties. The devices subject to this paragraph (b)(2) are exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.
