This is a 510(k) clearance letter for a medical device (nasal cannula), not an AI/ML-driven device. Therefore, the information typically requested for AI/ML device validation (such as expert consensus, MRMC studies, or training/test set details) is not applicable.
The document describes the device, its intended use, and a summary of non-clinical testing performed to demonstrate substantial equivalence to predicate devices. It clearly states that no clinical testing was performed.
Here's a breakdown of the requested information based on the provided document, highlighting why many points are not applicable for this type of device clearance:
-
A table of acceptance criteria and the reported device performance
- The document lists various non-clinical performance tests but does not provide a table of specific acceptance criteria with corresponding reported device performance values. Instead, it generally states that testing was conducted "to demonstrate substantial equivalence." For example, it lists "Relevant Humidity Output testing" but doesn't state the specific humidity output range considered acceptable or the measured output. This is typical for a 510(k) submission where broad equivalence is the goal rather than meeting precise performance thresholds for novel functionality.
-
Sample sizes used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Not applicable. This is a physical medical device. Testing involved bench tests on manufactured units, not data sets in the AI/ML sense. Data provenance, retrospective/prospective, and sample sizes for test sets (in the context of patient data) are not relevant as no human or clinical data was used for validation.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- Not applicable. No "ground truth" was established by experts in the context of diagnostic performance, image interpretation, or similar AI/ML applications, as this is a physical medical device.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not applicable. There was no test set requiring expert adjudication for performance evaluation.
-
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
- Not applicable. This is not an AI-assisted device, and no MRMC study was conducted. The document explicitly states "No clinical testing was performed."
-
If a standalone (i.e. algorithm only without human-in-the loop performance) was done
- Not applicable. This is not an algorithm-based device.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- Not applicable. The concept of "ground truth" as it applies to AI/ML model validation is not relevant here. The device's performance was evaluated against engineering specifications and industry standards for physical device functionality (e.g., flow rates, material compatibility, strength).
-
The sample size for the training set
- Not applicable. There is no AI/ML model, and thus no training set.
-
How the ground truth for the training set was established
- Not applicable. There is no AI/ML model, and thus no training set or ground truth establishment for it.
In summary, the provided document is a 510(k) clearance for a physical medical device, not an AI/ML-driven product. Therefore, most of the requested information related to AI/ML validation (ground truth, expert studies, training/test sets) is irrelevant to this submission.
The acceptance criteria for this device focus on:
- Biocompatibility: Meeting ISO standards (e.g., ISO 10993 series, ISO 18562 series) to ensure the materials are safe for patient contact and breathing gas pathways. The document lists the specific ISO standards used.
- Performance Bench Testing: Covering aspects like visual inspection, humidity output, thermal overshoot, connection strength, leak testing, headgear testing, shelf life, and useful life. While the specific numerical acceptance criteria for each test (e.g., "humidity output must be within X amount") are not explicitly listed in this summary, the document indicates these tests were performed and implicitly met the company's internal acceptance criteria for demonstrating substantial equivalence.
- Substantial Equivalence: The overarching acceptance criterion for a 510(k) is demonstrating that the device is "as safe and as effective" as a legally marketed predicate device, based on the non-clinical testing performed.
The "Study that proves the device meets the acceptance criteria" for this product consists of the various Non-Clinical Testing described on pages 16-17, primarily Biocompatibility Testing and Performance Testing (Bench), which were conducted to support the claim of substantial equivalence to the predicate devices.
§ 868.5450 Respiratory gas humidifier.
(a)
Identification. A respiratory gas humidifier is a device that is intended to add moisture to, and sometimes to warm, the breathing gases for administration to a patient. Cascade, gas, heated, and prefilled humidifiers are included in this generic type of device.(b)
Classification. Class II (performance standards).
