    AI/ML Overview

    The provided documentation is a 510(k) summary for an Electric Wheelchair (Robooter E60). This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than providing extensive details on a comprehensive clinical study to define and meet specific acceptance criteria in the same way one might for a novel diagnostic or therapeutic device.

    Based on the provided text, the "acceptance criteria" are primarily defined by compliance with a comprehensive set of ISO 7176 series standards for wheelchairs, along with other relevant ISO and ANSI standards. The "study" proving the device meets these criteria refers to the non-clinical testing performed against these standards.

    Here's the breakdown of the requested information based on the document:

    1. Table of Acceptance Criteria and Reported Device Performance

    The acceptance criteria are essentially the requirements set forth by the listed ISO and ANSI standards. The reported device performance is that it met these standards. Since the document doesn't provide specific numerical performance values for each standard (e.g., exact braking distance for a specific test case, or specific stability angles beyond the general 9° dynamic stability), but rather states "test results meet its design specification" or "all test results meet the requirements," a direct comparative table with quantitative acceptance vs. performance for each test is not fully derivable. However, we can represent the overall compliance.

    Acceptance Criterion (Standard Requirement)Reported Device Performance
    Biocompatibility: Conforms to ISO 10993-5 (Cytotoxicity), ISO 10993-10 (Sensitization), ISO 10993-23 (Irritation)All user directly contacting materials are compliant with ISO 10993-5, ISO 10993-10, and ISO 10993-23 requirements.

    Software Verification & ValidationValidation testing of the priority of the on-board "controller rocker" (joystick) over the wireless remote controllers was conducted.

    2. Sample Sizes used for the Test Set and Data Provenance

    The document does not specify sample sizes (e.g., number of devices tested) for the non-clinical tests. It refers to these as "non-clinical tests" and details the standards followed. The data provenance is implied to be from the manufacturer's testing facilities (Shanghai Bangbang Robotics Co., Ltd.) as part of their submission for market clearance. These are prospective tests conducted to demonstrate compliance. There is no mention of country of origin of the data in terms of patient data, as this is a non-clinical submission.

    3. Number of Experts used to establish the Ground Truth for the Test Set and the Qualifications of those Experts

    This information is not applicable and not provided. The "ground truth" for non-clinical performance standards is defined by the standards themselves (e.g., a specific static stability angle, braking distance, etc.). Compliance is assessed by accredited testing bodies or manufacturer's internal quality systems against these defined requirements. There are no "experts" in the context of clinical interpretation to establish ground truth in this non-clinical submission.

    4. Adjudication Method for the Test Set

    This is not applicable to non-clinical technical performance testing. Adjudication methods (like 2+1, 3+1) are typically used in clinical studies involving interpretation by multiple human readers (e.g., radiologists) to establish a consensus ground truth when individual reader opinions might differ.

    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 such study was done or reported. This submission is for an electric wheelchair, a physical medical device, not an AI-powered diagnostic or interpretive tool that would involve human readers. The document explicitly states "No clinical study is included in this submission."

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

    This is not applicable. The device is an electric wheelchair, not an algorithm, and the testing focuses on its physical and electrical safety and performance characteristics.

    7. The Type of Ground Truth Used

    The "ground truth" for the non-clinical tests is the performance metrics and criteria defined within the referenced international standards (ISO 10993, ISO 7176 series, ANSI C63.27) and the device's design specifications. For example, for static stability, the ground truth is the minimum stability angle specified by ISO 7176-1. For braking, it's the effectiveness criteria of ISO 7176-3.

    8. The Sample Size for the Training Set

    This is not applicable. This is a physical medical device, not a machine learning model that requires a training set.

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

    This is not applicable for the same reason as point 8.

    2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    The document does not specify a "test set" in the context of an AI algorithm or data. The performance testing is described as non-clinical testing to ensure compliance with relevant ISO standards. This typically involves testing of physical units of the device. Sample sizes for these types of engineering tests are not usually reported in the same way as for clinical trials or AI validation sets. Data provenance (country of origin, retrospective/prospective) is not applicable or provided.

    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)

    This is not applicable as there is no mention of a "test set" that requires expert-established ground truth. The acceptance is based on compliance with engineering and safety standards.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

    This is not applicable for the type of device and testing described.

    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

    This is not applicable since the device is an electric wheelchair, not an AI-powered diagnostic or assistive tool for human "readers" or clinicians.

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

    This is not applicable as the device is an electric wheelchair, not an algorithm.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

    The "ground truth" for this device's performance is adherence to the measurement and safety requirements specified in the various ISO and ANSI standards listed. For example, for static stability, the ground truth is simply whether the device maintained stability under the specified test conditions.

    8. The sample size for the training set

    This is not applicable as the device is a physical product, not an AI algorithm requiring a training set.

    9. How the ground truth for the training set was established

    This is not applicable.

    AI/ML Overview

    This document describes the FDA's 510(k) clearance for the Shanghai BangBang Robotics Co., Ltd. Electric Wheelchair (Model: BBR-LY-01-01). As such, it focuses on demonstrating "substantial equivalence" to a predicate device rather than providing a detailed study of the device's performance against specific acceptance criteria in the manner an AI/ML algorithm submission would.

    Therefore, many of the requested points are not applicable to this type of regulatory submission for a physical medical device. However, I can extract the relevant information regarding performance and testing.

    1. A table of acceptance criteria and the reported device performance

    For a physical device like an electric wheelchair, "acceptance criteria" are generally compliance with recognized consensus standards. The performance is reported as meeting these standards.

    Acceptance Criterion (Standard Compliance)Reported Device Performance (Compliance)
    Static Stability (ISO 7176-1:2014)Complies

    2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    This information is typically not included in a 510(k) summary for a non-software medical device. Testing against ISO standards usually involves a representative number of physical units, not a "test set" of data in the AI/ML sense. The testing would have been done by the manufacturer (Shanghai BangBang Robotics Co., Ltd. in China) and verified by a recognized testing body.

    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. For a physical device, "ground truth" is established by the direct physical measurement and performance testing against the specifications outlined in the international consensus standards (e.g., measuring stability, braking distance, dimensions). This does not involve expert consensus in the diagnostic sense.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

    Not Applicable. Adjudication methods like 2+1 or 3+1 are used for establishing ground truth in image interpretation or similar diagnostic tasks, typically for AI/ML algorithms. This is not relevant for the performance testing of an electric wheelchair.

    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. MRMC studies are specific to evaluating the impact of AI on human readers (e.g., radiologists interpreting images). This device is a physical product (electric wheelchair) and does not involve "human readers" or "AI assistance" in that context.

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

    Not Applicable. This device is an electric wheelchair, not an algorithm. While it has a control system and Bluetooth connectivity, its primary function is mechanical mobility, and it is always operated with a human in the loop (the user or a remote controller).

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

    The "ground truth" for this device's performance is compliance with international consensus standards (ISO 7176 series and others) through objective performance testing and measurement. For example, the braking distance being 120cm is a factual measurement, not an expert opinion or pathology finding.

    8. The sample size for the training set

    Not Applicable. This is not an AI/ML algorithm, so there is no "training set."

    9. How the ground truth for the training set was established

    Not Applicable. No training set exists for this type of device submission.
