Solcart B Powder Dialysis Concentrate is intended for use in bicarbonate hemodialysis for acute and chronic renal failure, or acute intoxication with dialyzable substances.

Solcart B consists of a powder concentrate used to prepare bicarbonate concentrate solution for use in hemodialysis. Solcart B is a non-refillable polypropylene cartridge containing dry sodium bicarbonate [in compliance with European Pharmacopoeia (Ph. Eur.) and United States Pharmacopoeia (USP)] for hemodialysis. It must be used together with a suitable acid concentrate and water meeting the requirements of the Association for the Advancement of Medical Instrumentation (AAMI). The Solcart B cartridge is designed to fit into cartridge holder adapters affixed to the hemodialysis machine. The 1100g cartridge may only be used with B. Braun hemodialysis machines for which the use of powder bicarbonate cartridges is a stated option and the machine is equipped with a holder for the bicarbonate cartridge.

This document describes the Solcart B Sodium Bicarbonate Powder Dialysis Concentrate, 1100g Cartridge, and its acceptance criteria for market clearance.

Here's the breakdown of the information requested:

1. Table of Acceptance Criteria and Reported Device Performance

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

The document does not specify exact sample sizes for the package/ship tests, performance tests, or stability tests. It generally states that "The proposed device was subjected to package and ship tests" and "performance testing was conducted," and "stability testing conducted."

• Data Provenance: The studies were conducted by B. Braun Avitum AG (Germany) and B. Braun Medical Inc. (USA). The nature of these tests (e.g., in-house testing, third-party validation) typically implies a prospective design for these specific engineering and performance evaluations.

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

This type of information (number and qualifications of experts) is not typically relevant or disclosed for this type of device (sodium bicarbonate powder for hemodialysis). The "ground truth" for this device's performance would be established by objective measurements against predefined chemical, physical, and functional specifications, rather than expert interpretation of complex data like medical images.

4. Adjudication Method (e.g., 2+1, 3+1, none) for the Test Set

Adjudication methods like 2+1 or 3+1 are used for studies involving subjective reader interpretations (e.g., medical imaging). For hardware/material testing of a hemodialysis concentrate, such methods are not applicable. The device performance is assessed through direct physical and chemical measurements.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was Done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

No MRMC comparative effectiveness study was conducted or is applicable for this device. This is a material component (sodium bicarbonate powder) for a hemodialysis system, not an AI-powered diagnostic or assistive tool for human readers.

6. If a Standalone (i.e. algorithm only without human-in-the loop performance) was Done

This question is not applicable. The device is a physical product (sodium bicarbonate powder cartridge), not an algorithm or software. It does not have a "standalone" or "human-in-the-loop" performance in the context of AI or software.

7. The Type of Ground Truth Used

The ground truth for this device's performance is based on predefined specifications for:

• Chemical composition and purity of sodium bicarbonate.
• Physical properties (e.g., concentration upon dissolution).
• Compatibility with B. Braun hemodialysis machines (functional performance).
• Stability over time.
• Integrity of packaging and shipping.

These specifications would be derived from industry standards (e.g., European Pharmacopoeia, United States Pharmacopoeia, AAMI) and internal product requirements.

8. The Sample Size for the Training Set

This question is not applicable. There is no "training set" in the context of machine learning or AI involved with this device. Performance is validated through standard engineering and pharmacological testing, not through training an algorithm.

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

This question is not applicable, as there is no training set for this device.
