The power wheelchair can be folded/ expanded manually. The Left and right handrails (joystick) can be interchange.

Here's a breakdown of the acceptance criteria and study information for the Power Wheelchair, based on the provided document.

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria for the Power Wheelchair (models D03, D05, D06, D09, D11, D16, D22, D23, D26, D36) are implicitly defined by compliance with a comprehensive set of ISO standards. The reported device performance is indicated by the statement that the device met all design specifications and passed all tests.

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

• Sample Size for Test Set: The document does not specify a distinct "test set" in terms of patient data or images. Instead, the testing refers to physical devices (the specific models D03, D05, D06, D09, D11, D16, D22, D23, D26, D36) and their components. The tests performed are bench tests conducted on these physical devices to verify their performance against engineering standards.
• Data Provenance: Not applicable as the testing involves physical device performance, not data from human subjects. The testing is prospective in the sense that the manufacturer tested their newly designed device models to confirm compliance. The manufacturing location is Anhui, China.

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

Not applicable. This is a technical performance study of a physical device against engineering standards. Ground truth as typically defined for AI/diagnostic studies (e.g., expert consensus on medical images) is not relevant here. The "ground truth" is defined by the technical specifications and requirements of the referenced ISO standards.

4. Adjudication Method for the Test Set

Not applicable. There is no human interpretation or consensus required for the test results; the tests involve quantifiable measurements (e.g., stability angles, braking distances, electrical properties) that either meet or do not meet the specified criteria in the standards.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No. An MRMC study is not relevant for this type of device (a power wheelchair). It's typically used for evaluating diagnostic or screening tools where human readers interpret patient data (e.g., radiology images).

6. If a Standalone Study (i.e., Algorithm Only Without Human-in-the-Loop Performance) Was Done

Yes, in essence, the entire suite of non-clinical bench testing constitutes a "standalone" evaluation of the device's physical and electrical performance without human operation as a variable beyond what is required to execute the test protocols. The Bluetooth remote control functionality (a form of "algorithm") was also tested in a standalone manner for effectiveness and cybersecurity.

7. The Type of Ground Truth Used

The "ground truth" (or reference standard) for these tests is the quantitative and qualitative requirements set forth in the extensive list of ISO and IEC engineering standards (e.g., ISO 7176 series, IEC 62133-2, IEC 60601-1-2, ANSI C63.27, ISO 14971, ISO 10993 series). These standards define the acceptable performance limits and test methodologies for power wheelchairs.

8. The Sample Size for the Training Set

Not applicable. This is not an AI/ML device where a "training set" of data is used for model development. The development process would involve engineering design and iterative prototyping, not data-driven model training.

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

Not applicable, as there is no training set for an AI/ML model.

The provided text is a 510(k) Premarket Notification from the FDA for a Power Wheelchair. It describes the device, compares it to predicate devices, and outlines the non-clinical testing performed to establish substantial equivalence. However, it does not contain information about a study proving the device meets acceptance criteria related to AI/ML performance, human reader improvement with AI assistance, or expert ground truth establishment for medical imaging or similar AI applications.

The document explicitly states:

• "No animal study and clinical studies are available for our device. Clinical testing was not required to demonstrate the substantial equivalence of the power wheelchair to its predicate device." (Page 17, Section IX)
• The comparison tables (Table 1, Table 2, Table 3) detail physical, mechanical, and electrical characteristics, and safety standards met (ISO, IEC, EMC, biocompatibility). These are engineering and safety performance criteria for a wheelchair, not AI/ML performance.

Therefore, I cannot provide the requested information regarding AI/ML acceptance criteria and a study that proves the device meets those criteria, as the provided text pertains to a power wheelchair and not a medical device involving AI/ML for diagnostic or therapeutic purposes.

If you have a document describing an AI/ML medical device and its validation study, please provide that, and I will be able to answer your questions.
