    AI/ML Overview

    The provided document is a 510(k) premarket notification for the Famidoc FDES106 Series Electro-Stimulator devices (including models FDES106, FDES106A, FDES105, and FDES107). It aims to demonstrate substantial equivalence to legally marketed predicate devices.

    Critical Note: This document explicitly states: "The FDES106(ED406) Series Electro-Stimulator did not conduct, nor rely upon, clinical tests to determine substantial equivalence." Therefore, there are no acceptance criteria based on clinical performance metrics (like sensitivity, specificity, accuracy), nor is there any study related to device performance in a clinical context reported within this document. The "acceptance criteria" and "device performance" in this context refer to adherence to established electrical, mechanical, and biocompatibility safety standards.

    Below is an analysis based on the information provided regarding the non-clinical tests and comparisons.


    Acceptance Criteria and Study to Demonstrate Device Meets Criteria

    1. Table of Acceptance Criteria and Reported Device Performance

    Since this is a 510(k) submission for an electro-stimulator, the acceptance criteria are generally based on compliance with recognized safety and performance standards for such devices, and substantial equivalence to predicate devices. The "reported device performance" refers to the device's adherence to these standards and its characteristics as compared to the predicates.

Details are provided in tables in the submission (e.g., Pages 9-11). The differences are presented as not affecting intended use or equivalence.
    Mechanical Features & DesignCompared to predicate devices, devices are internally powered equipment, have Type BF applied part protection, are Class II devices, and have similar features regarding output channels, treatment programs, materials of construction, automatic safety features (e.g., over current trip, no load trip, shut off time), and physical dimensions/weight. The differences are detailed in tables (e.g., Pages 5-8).

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

    • Test Set Description: The "test set" in this context refers to the Famidoc FDES106 Series devices themselves, which underwent non-clinical (bench) testing.
    • Sample Size: The document does not specify a quantitative sample size for the bench testing (e.g., "N units were tested"). It describes the tests generally applied to the device series. It is implied that representative units of each model (FDES106, FDES106A, FDES105, FDES107) were tested to demonstrate compliance.
    • Data Provenance:
      • Country of Origin: The test results are presumably from China, where the manufacturer (Famidoc Technology Co., Ltd.) is located.
      • Retrospective or Prospective: The testing described is prospective, in the sense that the devices were tested against established standards to support the premarket notification.

    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)

    • Ground Truth Establishment: For non-clinical device safety and performance testing, "ground truth" is established by recognized international and national standards (e.g., IEC 60601 series, ISO 10993 series, FDA software guidance). These standards represent a consensus among experts (engineers, medical professionals, regulatory bodies) over years of development and revision.
    • Number of Experts: Not applicable in the sense of individual expert review for each test outcome. Compliance is assessed against the defined requirements of the standards.
    • Qualifications of Experts: The experts involved are those who developed and maintain the relevant IEC and ISO standards, and FDA guidance documents. Their qualifications would typically include extensive experience in electrical engineering, biomedical engineering, materials science, toxicology, and regulatory affairs pertaining to medical devices.

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

    • Adjudication Method: Not applicable. The "adjudication" for non-clinical testing refers to the objective measurement of device parameters against the defined limits or requirements of the standard. There is no human subjective adjudication of the test results themselves, beyond internal quality control and regulatory review for compliance.

    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

    • MRMC Study: No. This is not an imaging or diagnostic device that relies on human readers interpreting results, nor does it incorporate AI. The device is an electro-stimulator for pain relief and muscle conditioning.
    • Effect Size of AI: Not applicable, as there is no AI component or MRMC study.

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

    • Standalone Performance Study: No. This is a physical medical device (electro-stimulator), not a software-only algorithm. The "software verification" mentioned confirms the software functions as designed and complies with FDA guidance, but it's not a standalone performance study in the sense of an algorithm.

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

    • Type of Ground Truth: The ground truth for this submission is compliance with international safety and performance standards (IEC, ISO) and FDA software guidance. This reflects an expert consensus on what constitutes a safe and acceptably performing electro-stimulator. The claims of "substantial equivalence" are based on comparing the device's characteristics to those of legally marketed predicate devices, which themselves have met these regulatory standards.

    8. The sample size for the training set

    • Training Set Sample Size: Not applicable. This is not a machine learning model, so there is no "training set."

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

    • Training Set Ground Truth Establishment: Not applicable, as there is no training set.

    Device Description

    The FDES101(ED401) Series Stimulator, which includes models FDES101(ED401), FDES102(ED402) and FDES103(ED403), are Transcutaneous Electrical Nerve Stimulator and muscle stimulator for pain relief and/or Electrical Muscle Stimulator. The stimulator sends gentle electrical current to underlying nerves and muscle group via electrodes applied on the skin. The parameters of units are controlled by the press buttons. Its intensity level is adjustable according to the needs of patients.
    The three models FDES101(ED401), FDES102(ED402) and FDES103(ED403) have the same housing in a molded portable plastic case with a viewable LCD display, an accessible keypad, and accessible battery storage compartment. The case shape is rectangular. The LCD is located on the upper half of the rectangular face of the device, above the keypad. The LCD is used to display system information to the user.
    The device is equipped with a keypad composed of push buttons which are located below the LCD. The function for each button is defined by a symbol on the LCD corresponding to the button immediately below it. The process to set the parameter and attach lead wires to the five models is also the same. Yet, they have different liquid crystal display and parameters for patients to create their own settings.
    The FDES101(ED401) TENS and EMS Stimulator is the combination unit with the TENS. EMS functions, the function can be selected by press buttons. The range of settings is identical to those of FDES102(ED402) and FDES103(ED403). The difference on the five units can be identified by the LCD display.

    AI/ML Overview

    The provided document is a 510(k) Summary for FAMIDOC TECHNOLOGY CO., LTD.'s FDES101 (ED401) Series Electro-Stimulator. It focuses on demonstrating substantial equivalence to a predicate device rather than providing the results of a de novo study with specific acceptance criteria and performance metrics typically associated with AI/ML device evaluations. Therefore, many of the requested elements are not applicable or cannot be extracted from this type of regulatory submission.

    However, I can extract the information relevant to non-clinical testing for substantial equivalence and general device specifications.

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

    For a 510(k) submission, the "acceptance criteria" for performance are typically substantial equivalence to a predicate device and compliance with relevant safety and performance standards. The "reported device performance" is demonstrated through these comparisons and adherence to standards.

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

    This document describes a 510(k) submission for an electro-stimulator, which is a hardware device. It demonstrates substantial equivalence through comparisons to a predicate device and adherence to international safety and performance standards.

    • No "test set" in the context of AI/ML performance evaluation (e.g., retrospective vs. prospective data, country of origin) is mentioned or applicable here.
    • The comparison is based on the technical specifications and safety testing of the device itself and its components, against those of a predicate device and industry standards.

    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. This is a hardware device submission, not specifically an AI/ML diagnostic or prognostic device that requires expert-established ground truth for a test set.

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

    Not applicable, as there is no "test set" or human expert review process described for performance evaluation in the context of an AI/ML device.

    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 hardware device submission, not an AI/ML device intended to assist human readers. The document explicitly states: "The FDES101(ED401) Series Electro-Stimulator did not conduct, nor rely upon, clinical tests to determine substantial equivalence."

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

    Not applicable. The device is a physical electro-stimulator, not an algorithm.

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

    Not applicable. For this type of device, "ground truth" relates to compliance with engineering and safety standards, and functional equivalence to an already legally marketed device, rather than diagnostic accuracy against a clinical reference standard. The "proof" is through non-clinical bench testing and comparative analysis of specifications against predicate devices.

    8. The sample size for the training set

    Not applicable. This is a hardware device, not an AI/ML algorithm requiring a training set.

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

    Not applicable. As above, this is a hardware device, and the concept of a training set and its ground truth is not relevant to this submission.


    Summary of the Study that Proves the Device Meets Acceptance Criteria:

    The study proving the device meets its "acceptance criteria" (which in this 510(k) context is primarily substantial equivalence to a predicate device and compliance with recognized safety standards) is a non-clinical bench testing and comparative analysis study.

    • The document explicitly states: "The FDES101(ED401) Series Electro-Stimulator did not conduct, nor rely upon, clinical tests to determine substantial equivalence. Nonclinical testing was performed in order to validate the design according with the company's specified design requirements, and to assure conformance with the following voluntary design standards:"

      • IEC 60601-1 "Medical electrical equipment Part 1: General requirements for safety".
      • IEC 60601-1-2 "Medical electrical equipment Part 1-2: General requirements for basic safety and essential performance - Collateral Standard: Electromagnetic compatibility- Requirements and tests, Interpretation Sheet."
      • IEC 60601-1-4 "Medical electrical equipment Part 1-4: General requirements for safety - Collateral standard: Programmable electrical medical systems"
      • IEC 60601-2-10 "Medical electrical equipment Part 2: Particular requirements for the safety of nerve and muscle stimulators"
    • Evidence of Compliance: The submission includes bench testing results, safety reports, and a Risk Analysis Report to demonstrate that any engineering differences from the predicate device "do not affect the intended use or alter the fundamental scientific technology of the device," thus maintaining "the same safety and effectiveness as that of predicate device." Specific comparisons like power source, patient leakage current, electrical/mechanical safety classifications, and material properties are presented.

    • Data Provenance: The comparative data is derived from the technical specifications and test results of the new device manufactured by Famidoc Technology Co., Ltd. (China) and the predicate device (MT9000 Series Electro-Stimulator, K093138, manufactured by Shenzhen Dongdixin Technology Co., Ltd.). This is a retrospective comparison based on existing device specifications and non-clinical test data.

    Intended Use

    Famidoc Infrared Thermometers, models: FDIR-V2, FDIR-V4, FDIR-V5, FDIR-V6, FDIR-V7, FDIR-V9, FDIR-V9-3, FDIR-V10, FDIR-V15, are intended for intermittent measurement and monitoring of human body temperature by consumers in the home.

    Device Description

    Famidoc Infrared FDIR series Thermometers are hand-held, reusable, battery operated devices, which can measure human body temperature in two ways.

    • On forehead, the skin temperature on one's forehead.
    • In ear, the tympanic temperature in one's ear.
      The operation principle is based on Infrared Sensor technology. The IR sensor can output different signal when measuring different object temperature or in different ambient temperature, and the ASIC can turn the signal from IR Sensor to a digital value and display it on the LCD.
      The subject devices (Models: FDIR-V2, FDIR-V4, FDIR-V6, FDIR-V6, FDIR-V7, FDIR-V9, FDIR-V9-3, FDIR-V10, FDIR-V15) are the same series in Famidoc. Their design principle, intended use, indications for use, material, control keys, software and the applicable standards are the same. The differences between them are appearance, some parameters (e.g. LCD size), and some minor functions (e.g. Voice function).
    AI/ML Overview

    The provided document is a 510(k) summary for an Infrared Thermometer. It focuses on demonstrating substantial equivalence to a predicate device rather than presenting a detailed study with specific acceptance criteria and performance metrics for a novel AI/device.

    Therefore, the requested information cannot be fully extracted as it pertains to a different type of device evaluation (e.g., for an AI/ML medical device).

    However, I can provide what information is available in the document regarding performance and equivalence:

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

    The document does not explicitly state acceptance criteria in terms of numerical performance metrics for the thermometer's accuracy against a ground truth. Instead, it relies on conformance to standards.

    Acceptance Criteria (Inferred from standards conformance)Reported Device Performance (from the document)

    Intended Use

    Famidoc Digital Clinical Thermometers are intended for the measurement and monitoring of human body temperature, by doctor or consumers in the hospital or home. It is used alone for human beings at all ages.

    Device Description

    Famidoc Digital Clinical Thermometer (model FDTH-V0-1, FDTH-V0-2, FDTH-V0-3, FDTH-V0-4) are hand-held, reusable, battery operated, maximum device that can measures human body temperature. Models FDTH-V0-1, FDTH-V0-2, FDTH-V0-3, FDTH-V0-4 have the same indication for use. the difference points are their shapes、waterproof function and measurement speed. The operation principle is based on thermistor and ASIC technology, a thermistor using as temperature sensor, the sensor's signal is then calculated and displayed by an ASIC. The digital thermometer comprises a thermistor for temperature sensing, a reference resistor for comparing the resistance of the thermistor, a buzzer for sounding effect, an ASIC and a LCD for calculating and displaying the target temperature digitally which the thermistor is immersed.

    AI/ML Overview

    The document provided describes the Famidoc Digital Clinical Thermometer and its FDA 510(k) summary. Here's a breakdown of the requested information based on the provided text:

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

    Acceptance CriteriaReported Device Performance
    Standards Met:
    ASTM Standard Specification for Electronic Thermometer for intermittent Determination of Patient Temperature (ASTM Ell12-00)Bench testing confirmed accuracy, precision, and repeatability measurements specified in the labeling.
    IEC 60601-1Met
    IEC 60601-1-2Met
    EN 12470-3:2000 (repeatability and standard deviation)Clinical tests proved repeatability and standard deviation are in accord with the demand of EN 12470-3:2000 when applied to humans.

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

    The document mentions "clinical tests" for repeatability and standard deviation based on EN 12470-3:2000. However, it does not specify the sample size used for these tests. The country of origin and whether the data was retrospective or prospective are not mentioned.

    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 information is not provided in the document. The nature of the device (a thermometer) suggests that ground truth would likely be established by a reference temperature standard rather than expert consensus on interpretation.

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

    This information is not provided in the document. Given the type of device, an adjudication method as typically described for image analysis or diagnostic interpretation by experts would not be applicable.

    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

    A multi-reader multi-case (MRMC) comparative effectiveness study is not mentioned in the document. This type of study is typically relevant for AI-powered diagnostic tools that assist human readers, which is not the function of a digital clinical thermometer.

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

    The device itself is a standalone electronic thermometer. The "bench testing" mentioned for accuracy, precision, and repeatability, as well as the "clinical tests" for repeatability and standard deviation, effectively constitute standalone performance assessments. The performance reported in the table (meeting ASTM and IEC standards) is the standalone performance of the device.

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

    For the bench testing and clinical tests, the ground truth would inherently be a highly accurate reference temperature (e.g., from a calibrated standard thermometer or controlled thermal environment). The document doesn't explicitly state "reference temperature" as the ground truth but refers to meeting standards like ASTM Ell12-00, which govern the accuracy of thermometers against such reference standards.

    8. The sample size for the training set

    The device described is a digital clinical thermometer, which is a physical measurement device based on thermistor and ASIC technology. It does not involve a "training set" in the context of machine learning or AI algorithms. Therefore, this question is not applicable to the described device.

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

    As there is no "training set" for this type of device, this question is not applicable.

    1. on forehead, the skin temperature on one's forehead.
    2. in ear, the tympanic temperature in one's ear.
      The operation principle is based on Infrared Sensor technology. IR Sensor can putout different signal when measuring different object temperature or in different ambient temperature, an ASIC can turn the signal from IR Sensor to a digital value and display it by LCD.
    AI/ML Overview

    The provided text does not contain detailed information about a specific study with acceptance criteria and reported device performance in the format requested.

    The document is a 510(k) summary for an Infrared Thermometer. It states that "The device conforms to applicable standards included ASTM E1965-98, EN 12470-5: 2003, IEC 60601-1 and IEC 60601-1-2 requirements." and that "tests in this submission provide demonstrate these small difference do not raise and new questions of safety or effectiveness." This implies that the device was tested against these standards, and its performance met the requirements within them, leading to the conclusion of substantial equivalence to a predicate device.

    However, the specific "acceptance criteria" (e.g., accuracy +/- 0.X degrees C), the numerically "reported device performance," and other details like sample sizes, ground truth establishment, or expert involvement are not explicitly provided in this 510(k) summary. These details would typically be found in the full test reports referenced by the submission to FDA.
