The summary describes a standard infrared thermometer and does not mention any AI or ML capabilities.
No
The device is described as an "electronic clinical thermometer" used to "detect body temperature," which indicates a diagnostic rather than therapeutic purpose.
No
The device is an electronic clinical thermometer used to detect body temperature, which is a measurement tool rather than a device intended for diagnosing a disease or condition.
No
The device description explicitly states it uses an "infrared sensor (thermopile)" to detect temperature, indicating a hardware component is essential to its function.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used outside of the body (in vitro).
- Device Function: The Microlife Digital Infrared Ear Thermometer measures body temperature directly from the auditory canal using infrared radiation. It does not analyze a sample taken from the body.
- Intended Use: The intended use is to detect body temperature, not to diagnose a disease or condition based on a biological sample.
Therefore, based on the provided information, the device is a clinical thermometer used for measuring body temperature, which is not an IVD.

The major differences between the subject modified device IR1DN1 (IR210), and the predicate device IR1DB 1 are the measurement range, probe cover, position indicator, measuring probe and buttons material.
The Indications for Use statement of the subject device is identical to the predicate device. Other differences between the devices are:
1. Measurement range (body mode)
The subject device IR1DN1 (IR210) body mode measurement range is 32.0-43.0 ℃ (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 accommodate more physiologically relevant temperatures. This does not introduce any new risk to the device.
2. Accuracy (blackbody mode)
The modified device's accuracy: ±0.2 °C: 35.0 ~ 42.0 °C, ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------±0.4°F:95.0107.6 °F ±0.5°F:89.694.8°F&107.8~109.4 °F
The predicate device's accuracy: ±0.2°C: 32.042.2°C, ±0.4°F, 89.6108.0°F.
The modified device's measurement range and accuracy are wider than the predicate device. ; these are based on device's performance standards and patient's requirement. These differences do not affect the performance and accuracy according to our Reliability Test Report (ASTM E1965- 98), ISO 80601-2-56 Test Report, and our Clinical Test Report of IR1DN1 (IR210).
9
3. Memory
The modified device IR1DN1 (IR210) can recall the last 30 readings, whereas the predicate device IR1DB1 can only recall the last reading. Only storage reading quantity is different which does not affect the device's performance or safety and effectiveness.
4. Error
Both modified device IR1DN1 (IR210) and the predicate device IR1DB1 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. IR1DN1 (IR210) device will display icon "Er6", IR1DB1 will display icon "Err". Although the icons are different, the purpose is the same. This does not affect the device's performance or safety and effectiveness.
5. Sensor Type
The sensor type of the modified device is TPS23B, whereas the sensor type of the predicate device is OTP-668D2. The difference does not affect the performance and accuracy according to Reliability Test Report (ASTM E1965-98), ISO 80601-2-56 Test Report and Clinical Test Report of IR1DN1 (IR210).
6. Measuring probe material
The measuring probe material of the subject device is PCTG, whereas the measuring probe material of the predicate device is ABS707. The probe is not the patient contacting material. Biocompatibility testing was performed on the PCTG material in accordance with ISO 10993 standard and testing results proved the subject probe material to be biocompatible.
7. Probe cover
The subject device measures with rigid cover (PP), whereas the predicate device measures with a soft cover (PE). Biocompatibility testing was performed on the finished subject probe cover according to the ISO10993 standard. Our Biocompatibility Test Report of the PP material (Rigid Probe Cover) proves the subject probe cover material to be biocompatible. Our Clinical Test Report of IR1DN1 (IR210), showed that the subject probe cover did not affect the subject modified device's accuracy and performance.
8. Position indication
The subject device includes a position indication feature which was not included with the predicate device. This feature has been validated and verified through performance testing and clinical testing.
10
9. IC (Integrated Circuitry)
The integrated circuit model and its features have changes have been verified through performance testing.
10. "Start"/ "Power" button
The button material of the subject device is PMMA, whereas the button material of the predicate device is ABS707. The PMMA material's biocompatibility testing was performed according to ISO10993 standard. Biocompatibility Test Report of PMMA testing proved that the subject button material to be biocompatible.
Based on the aforementioned modifications to the subject device, the subject device does not raise different types of safety and effectiveness questions when compared to the predicate device.
Performance Testing
Testing information demonstrating performance of the Microlife Digital Infrared Ear Thermometer, Model IR1DN1 (IR210) 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.
The following testing was conducted to prove safety and effectiveness as well as substantial equivalence to the predicate devices:
| 1 | AAMI/ANSI ES60601-

Performance Testing Summary
A risk assessment was conducted in accordance is ISO 14971:2007/EN ISO 14971:2012 to assess risk management activities due to modifications to our predicate device. Verification activities that were performed included modifications, associated risk, validation method, and results revealed that all acceptance criteria passed.
Clinical Tests Conducted
Clinical testing was conducted according to ASTM E1965-98 and ISO 80601-2-56. This clinical study is a randomization, simple blind homologous control, pairing design of clinical investigation, consists of 114 subjects, of which 1/3 are infants, 1/3 are children and the rest 1/3 are adults (NOTE: Infants---newborn to one year: Children--- greater than one to five years; Adults---greater than five years old.). The test reports demonstrated that the clinical data, represented by clinical bias, with uncertainty of bias, and clinical repeatability, met the acceptance criteria of the clinical study protocol.
Conclusions
Based on the performance testing, comparison, analysis, and risk assessment, it demonstrated that the Microlife Digital Infrared Ear Thermometer IR1DN1 (IR210) is substantially equivalent to the Microlife Digital Infrared Ear Thermometer IR1DB1, cleared under K003308.
