The Puritan Bennett GoodKnight H2O is an accessory intended to warm and add moisture to the inspiratory gas flow for administration to a patient undergoing CPAP or bi-level therapy.
It is intended for use with adult patients receiving CPAP or Bi-level therapy for the treatment of Obstructive Sleep Apnea in the homecare and hospital environments.
The GoodKnight H2O is a microprocessor-controlled heated passover humidifier used to provide evaporated water content to dry breathing gases, during treatment of Obstructive Sleep Apnea.
The GoodKnight H2O has an ABS enclosure and a heater plate positioned in the front of the unit. A humidification chamber slides onto the heater plate and is held in place by a rim on the enclosure. The unit controls are located at the back of the device.
The technological characteristics of the GoodKnight H2O Heated Humidifier are equivalent to that of the predicate device.
The GoodKnight H2O is equivalent in terms of type (heated passover humidification), configuration (chamber, mounting arrangements), environmental conditions of use and control method (software).
Non-clinical testing of the GoodKnight HyO has been carried out and covered mechanical safety, electrical safety, thermal safety, EMC, software verification and validation and performance.
The GoodKnight H2O meets the performance and safety requirements of ISO 8185 related to humidification systems and which includes also the requirements of IEC 60601-1. The product complies also to the relevant USA deviations from UL 2601-1 and to the applicable requirements of the FDA Reviewers Guidance (November 1993).
The provided text is a 510(k) summary for the Puritan Bennett GoodKnight H2O Heated Humidifier. It describes the device, its intended use, and claims substantial equivalence to a predicate device. However, it does not contain the detailed information necessary to answer all parts of your request regarding acceptance criteria and a specific study proving the device meets those criteria, particularly in the context of an AI-powered device.
The document discusses non-clinical testing for mechanical, electrical, thermal safety, EMC, software verification, validation, and performance. It also states the device "meets the performance and safety requirements of ISO 8185 related to humidification systems and which includes also the requirements of IEC 60601-1."
Since this is a non-AI medical device (a heated humidifier), many of your questions related to AI-specific elements (like sample size for test/training sets, experts for ground truth, MRMC studies, standalone algorithm performance) are not applicable or cannot be answered from the provided text.
Here's what can be extracted and inferred:
1. A table of acceptance criteria and the reported device performance
| Acceptance Criteria Category (Derived from Standards) | Reported Device Performance |
|---|---|
| Mechanical Safety (per ISO 8185, IEC 60601-1, UL 2601-1) | Met requirements. Specific parameters not detailed, but likely include structural integrity, material compatibility, and resistance to physical stress during normal use. |
| Electrical Safety (per ISO 8185, IEC 60601-1, UL 2601-1) | Met requirements. Specific parameters not detailed, but likely include leakage currents, dielectric strength, and grounding integrity. |
| Thermal Safety (per ISO 8185, IEC 60601-1, UL 2601-1) | Met requirements. Specific parameters not detailed, but likely include surface temperatures, heating element control, and prevention of overheating. |
| Electromagnetic Compatibility (EMC) (per relevant standards) | Met requirements. Specific parameters not detailed, but likely involve emission and immunity standards. |
| Software Verification and Validation (per relevant standards and FDA Guidance) | Met requirements. Confirms software functions as intended and meets specifications. |
| Humidification Performance (per ISO 8185) | Met performance requirements. Specific humidification output (e.g., water vapor content, temperature) not detailed, but ISO 8185 specifies minimum humidification performance for respiratory gas humidifiers. |
| Overall Safety and Effectiveness (per FDA Reviewers Guidance) | Deemed to operate safely in its intended environment and be effective in fulfilling its intended use. |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
This document describes non-clinical testing on the device itself, not a machine learning model. Therefore, "test set" and "data provenance" in the AI context are not applicable. The testing was likely conducted in a laboratory setting (Mallinckrodt Développement France).
3. 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. Ground truth for a physical device's performance is established through objective measurements against a standard, not by expert consensus on data interpretation.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. This is for an AI algorithm evaluating data.
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
Not applicable. This is a physical medical device, not an AI assistance system.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. There is no algorithm in the AI sense. The device operates "standalone" in its intended function.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" for this device's performance would be established through objective physical measurements against the specified limits and ranges defined in the referenced international standards (ISO 8185, IEC 60601-1, UL 2601-1, and FDA Reviewers Guidance). For example, temperature measurements for thermal safety, electrical measurements for electrical safety, or humidity measurements for humidification performance.
8. The sample size for the training set
Not applicable. There is no AI training set for this physical device.
9. How the ground truth for the training set was established
Not applicable.
