Device Description

The Microlife Non-Contact Infrared Forehead Thermometer, Model FR1DG1 (NC200) is an electronic thermometer using an infrared sensor to measure infrared energy radiated from the forehead. This energy is collected through the lens and converted to a temperature value. The device uses CapSense Technology to detect distance this technology is used to assist measurement. The concept of proximity sensor detects human electrical proximity level to transform to distance. The distance control feature is added to the user interface to identify the measurement distances are in the correct parameter. In other words, the device will enter into measurement mode after the correct measurement distance is detected. This device can take a measurement automatically when the device detects the distance is appropriate within 5 cm.

AI/ML Overview

The provided text describes the Microlife Non-Contact Infrared Forehead Thermometer, Model FR1DG1 (NC200), and its comparison to a predicate device (Microlife Non-Contact Infrared Forehead Thermometer FR1DZ1, K100953) for substantial equivalence in an FDA 510(k) submission.

Here's an analysis of the acceptance criteria and study information:

1. Table of Acceptance Criteria and Reported Device Performance

The document states that the Microlife Non-Contact Infrared Forehead Thermometer, Model FR1DG1 (NC200) intends to meet the accuracy requirements of the ISO 80601-2-56: 2017 standard (implicitly, as it's listed as a standard the device was tested against and clinical testing was done according to ASTM E1965-98, which typically defines accuracy limits for clinical thermometers).

The device's reported laboratory accuracy is as follows:

Temperature Range (°C)	Accuracy (°C)	Temperature Range (°F)	Accuracy (°F)
35.0 ~ 42.0	±0.2	95.0 ~ 107.6	±0.4
34.0 ~ 34.9	±0.3	93.2 ~ 94.8	±0.5
42.1 ~ 43.0	±0.3	107.8 ~ 109.4	±0.5

The document also mentions that "the test report demonstrated that the clinical data, represented by clinical bias met the acceptance criteria of the clinical study protocol." However, the specific numerical acceptance criteria for clinical bias are not explicitly stated in the provided text.

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

Sample Size for Test Set: 116 subjects.
- 38 infants (newborn to one year)
- 41 children (greater than one to five years)
- 37 adults (greater than five years old)
Data Provenance: The document does not explicitly state the country of origin. It describes a "clinical study" which implies prospective data collection, but does not explicitly state "prospective."

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

This information is not provided in the document. The study is described as a "randomization, simple blind homologous control, pairing design of clinical investigation," and it states that "clinical bias met the acceptance criteria," suggesting a comparison against a reference thermometer measurement taken by an expert, but the number and qualifications of such experts are not detailed.

4. Adjudication Method for the Test Set

The adjudication method is not explicitly stated. The study design mentions "simple blind homologous control" and "pairing design," but doesn't specify how ground truth discrepancies (if any) were resolved or if multiple readers were involved in establishing the ground truth measurements.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

This information is not provided. The text describes a clinical study to assess the accuracy of the device itself, not a comparative effectiveness study involving human readers with and without AI assistance. The device is a thermometer, not an AI diagnostic tool.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

Yes, a standalone study was performed. The clinical testing described is primarily focused on the device's ability to measure temperature directly, without human interpretation of complex images or data where "human-in-the-loop" would typically apply. The "clinical bias met the acceptance criteria" refers to the instrument's performance.

7. Type of Ground Truth Used

The ground truth used was clinical data obtained from a "randomization, simple blind homologous control, pairing design of clinical investigation." In thermometer studies, this typically involves comparing the device's readings against a highly accurate reference thermometer (e.g., a rectal or oral mercury/electronic thermometer, or another gold standard for body temperature measurement) by an expert under controlled conditions. The term "clinical bias" supports this interpretation.

8. Sample Size for the Training Set

This information is not provided. The document makes no mention of a "training set," as the device is a medical measurement instrument. While it has algorithms (e.g., PH15.0 Algorithm for temperature calculation), these are typically developed through engineering and calibration, not through machine learning training sets in the same way an AI diagnostic algorithm would be.

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

This information is not provided, as the concept of a "training set" with established ground truth in the context of machine learning does not directly apply to the development and validation of this type of electronic thermometer. The algorithms for temperature calculation would be based on physical principles, calibration, and engineering, rather than a data-driven training process with labeled ground truth data.

{6}------------------------------------------------

{7}------------------------------------------------

The major differences between the subject modified device FR1DG1 (NC200), and the predicate device FR1DZ1 are the measurement range, auto measurement, and button material.

The Indications for Use statement of the subject device is identical to the predicate device. Other differences between the devices are:

1. Physical Dimension

The physical dimension of the subject device FR1DG1 is 156.7 x 43 x 47 mm, while predicate device FR1DZ1 is 150 x 40 x 39 mm. The difference is caused because of their different appearance, but the difference does not raise any new safety and effectiveness questions. This has been tested and confirmed according to IEC 60601-1-2 EMC; IEC 60601-1, AAMI/ANSI ES60601-1 Safety Test Report and ISO 80601-2-56 Test Report.

2. Measurement range

The subject device IR1DN1 (IR210) body mode measurement range is 32.0-43.0 °C (89.6-109.4 °F), whereas the predicate device IR1DB1 measurement range is 32.0°C ~42.2°C (89.6 ~108.0 °F). The subject device has a wider body mode measurement range to

{8}------------------------------------------------

accommodate more physiologically relevant temperatures. This does not introduce any new risk to the device.

3. Accuracy (blackbody mode/laboratory)

The modified device's accuracy: ±0.2 °C: 35.0 ~ 42.0 °C, ±0.3 °C: 34.0 ~ 34.9 °C & 42.1 ~ 43.0 °C ±0.4 °F: 95.0 ~ 107.6 °F, ±0.5 °F: 93.2 ~~94.8 °F & 107.8~~109.4 °F

The predicate device's accuracy: ±0.2 °C: 36°C to 39°C, ±0.3 °C: 34°C to 35.9°C & 39.1°C to 42.2°C

±0.4 °F: 96.8 - 102.2°F, ±0.5 °F: 93.2 - 96.6°F) &102.4 - 108.0°F

The modified device's measurement range is wider than predicated model; these are based on device's performance standards and client's requirement. These differences do not affect the performance and accuracy.

4. Operating conditions

The operating temperature range of modified device FR1DG1 (NC200) body mode is15~~40°C (59°F~~104°F),whereas the temperature range of predicate device FR1DZ1 is 16~ 40°C (60.8~104°F).The modified device's operating temperature range is wider than predicated model; this is based on device's performance standards . The difference does not affect the performance and accuracy which was evaluated in the performance testing.

5. Storage conditions

The storage temperature range of modified device FR1DG1 (NC200) is -25 ~ 55 °C (-13°F ~~131°F), whereas storage temperature range of predicate device FR1DZ1 is -20~~ 50 °C (-4 ~122°F). The modified device's storage temperature range is wider than predicated model: this is based on device's performance standards and client's requirement. The difference does not affect the performance and accuracy which was evaluated in the performance testing.

6. Date, time, beeper setting

The modified device FR1DG1 (NC200) has date, time, and beeper setting functions, whereas predicate device FRD1Z1 does not have these functions, and these functions do not affect device's performance, safety and effectiveness.

7. Error

Both modified device FR1DG1 (NC200) and the predicate device FR1DZ1 have self-test function. The principle of self-test is the same. Devices can perform a self-test every time when it is switched on to always guarantee the specified accuracy of any measurement, when it has error, it will display signal. FR1DG1 (NC200) device will display icon "Er6", "Er 0", FR1DZ1 will display icon "Err". Although the icons are different, but the purpose means are the same. It does not affect device's performance, safety and effectiveness.

8. Automatic switch-off

The modified device FR1DG1 (NC200) will automatic switch-off approx. 1 minute after last measurement has been taken, whereas predicate device FR1DZ1 will automatic switch-off approximately 3 minute after last measurement has been taken. This is based on client's requirement and it does not affect device's performance, safety and effectiveness.

9. Auto measurement

The software of modified device FR1DG1 (NC200) allows the user to take a simple way to test the body temperature. The software using CapSense Technology to detect distance,

{9}------------------------------------------------

this technology is used to assist measurement, a capacitive sensor detects changes in capacitance to determine the presence of a proximity to conductive objects, the capacitive sensor is embedded in the device probe, the CapSense Controller connects the capacitive sensor and the output to the MCU through a communication interface, such as an I2C. When the device detects the distance is appropriate within 5cm, the device will start measurement automatically, whereas predicate device FR1DZ1 does not have this function, as user need to aim the probe at the center of the forehead with any distance of no more than 5cm and keep pressing the "Start "button to take measurement. The Description and Verification Report of FR1DG1 (NC200) auto measurement function has a detailed description of auto measurement function. It does not affect the performance, safety and effectiveness which was evaluated in the performance testing.

10. Algorithm

The algorithm of Subject model FR1DG1 is PH15.0, while predicate model FR1DZ1 is PS12.The only difference is the algorithm version, because these two models have different UI. However, their temperature calculation algorithm is the same. It does not affect performance and accuracy which was evaluated in the performance testing.

11. Signal processing

For the Subiect model FR1DG1.thermopile and thermistor of the sensor convert the digit signal via 24 bit analog-to digital converter, then calculate the temperate via temperature calculation algorithm, while predicate model FR1DZ1 using 16 bit analog-to digital converter. Their principle is the same, only different bits. 24 bit is more precise than 16 bit. It does not affect performance and accuracy which was evaluated in the performance testing.

12. IC (Integrated Circuitry)

The main IC of the modified device is HY11P14, whereas the IC of the predicate device is SN8P1919. Their temperature calculation algorithms are the same. Just the model is different, and it does not affect performance and accuracy which was evaluated in the performance testing.

13. Touch IC (Integrated Circuitry)

The modified device FR1DG1 (NC200) has touch IC, whereas predicate device FR1DZ1 does not have touch IC. The difference does not affect the performance, safety and effectiveness which was evaluated in the performance testing.

14. Patient-Contact Button material

The button material of modified device FR1DG1 (NC200) is Polymethyl methacrylate (PMMA), whereas the button material of predicate device FR1DZ1 is ABS707. Biocompatibility testing was leveraged from Microlife Digital Infrared Ear Thermometer, Model IR1 DN1 (IR210) (K183663 reference device).

Non-Clinical Performance Testing

Testing information demonstrating performance of the Microlife Non-Contact Infrared Forehead Thermometer, Model FR1DG1 (NC200) in the intended environment of use is supported by testing that was conducted in accordance with Guidance on the Content of Premarket Notification [510(K)] Submissions for Clinical Electronic Thermometers.
