2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the specific sample sizes used for each non-clinical performance test. It mentions that tests were performed on "proposed device" or "relevant device configurations," implying that samples of the SANSIN Tubing Sets were used.
Data provenance: Given that the manufacturer is Jiangxi Sanxin Medtec Co., Ltd. in Nanchang, Jiangxi, China, and the listed contact person is in Shanghai, China, the data provenance is China. All tests appear to be retrospective (performed on completed devices or materials) and conducted by the manufacturer or a third-party testing facility.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This section is not applicable as the studies described are non-clinical (bench testing) rather than clinical studies involving expert interpretation of patient data. The "ground truth" for these tests is based on objective, quantifiable measurements against established standards and design specifications.
4. Adjudication Method for the Test Set
This section is not applicable as no adjudication method is mentioned or required for non-clinical bench testing. The results are based on objective test measurements.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is relevant for diagnostic devices that involve human interpretation of medical images or data. The SANSIN Tubing Sets are physical medical devices used for delivering hemodialysis, and their performance is evaluated through non-clinical bench tests and compatibility assessments, not human reading studies.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
This question is not applicable as the device is not an algorithm or AI system. It is a physical medical device. The "standalone" performance here refers to the device's ability to meet its specifications independently, which is what the non-clinical tests demonstrate.
7. The Type of Ground Truth Used
The ground truth used for these non-clinical tests is predominantly:
- Established consensus standards: Such as various parts of ISO 10993, ISO 11135, ASTM F88, ASTM F1929, USP, ISO 594-2, and ISO 8638.
- Internal design specifications: For tests like Repeated Closing, Tensile Strength, Endurance Pump, Pressure Leak, Priming Volume, Tubing Compliance, Mechanical Hemolysis, and Stimulated Operation where specific quantitative thresholds would be defined internally by the manufacturer to ensure functional performance and equivalence to the predicate.
- Predicate device characteristics: For comparison of physical performance parameters (e.g., length, priming volume, negative pressure, inner diameter), although the proposed device did not always match the predicate, the testing demonstrated that the proposed device's different characteristics did not raise new safety or effectiveness concerns.
8. The Sample Size for the Training Set
This section is not applicable as the device is not an AI/ML algorithm that requires a training set.
9. How the Ground Truth for the Training Set Was Established
This section is not applicable as the device is not an AI/ML algorithm that requires a training set.

2. Sample Size and Data Provenance
The document does not explicitly state the specific sample sizes used for each non-clinical test (e.g., for BFE, PFE, fluid resistance). It only presents the "Average" values, implying that multiple samples were tested.
The data provenance is from non-clinical tests conducted by the manufacturer, Jiangxi Sanxin Medtec Co., Ltd., based in China. The studies are retrospective in the sense that they are conducted on the finished device to demonstrate compliance with standards.
3. Number of Experts and Qualifications for Ground Truth
This information is not applicable as the evaluation relies on objective non-clinical performance standards and laboratory testing rather than expert-derived ground truth.
4. Adjudication Method for the Test Set
This is not applicable as the device performance is evaluated against predefined objective standards and laboratory test results, not through expert adjudication of ambiguous cases.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No MRMC comparative effectiveness study was done. The device is a medical face mask, and its evaluation is based on material properties and barrier performance, not on interpretation by human readers.
6. Standalone Performance Study
Yes, a standalone (i.e., algorithm only without human-in-the-loop performance) study was done, though the "algorithm" here refers to the device itself, not a software algorithm. The non-clinical tests assess the inherent performance characteristics of the face mask (e.g., filtration efficiency, fluid resistance) independently of human interaction.
7. Type of Ground Truth Used
The ground truth used is based on objective performance standards and laboratory test results as defined by recognized standards such as ASTM F2100:2019. These standards specify quantitative thresholds for various performance metrics (e.g., filtration percentages, pressure differentials, fluid resistance levels).
8. Sample Size for the Training Set
This information is not applicable. The device is a physical product (medical face mask), not an AI/ML algorithm that requires a "training set." The materials and manufacturing processes are designed to meet the performance criteria, and the non-clinical tests verify this compliance.
9. How the Ground Truth for the Training Set Was Established
This is not applicable as there is no "training set" in the context of this device. The design and manufacturing are based on established engineering principles and material science to achieve the required performance for medical face masks as outlined in relevant standards.
