Intended Use

The infrared thermometer is intended for the measurement and monitoring of human body temperature by doctors or customers in the hospital or at home.

Device Story

EFT-16 series infrared thermometers measure human body temperature via infrared radiation emitted from the forehead or ear. The device uses a Fresnel lens to focus infrared energy onto an internal sensor; a signal processor converts this input into a temperature reading, which is displayed on an LCD screen. Operated by clinicians or patients in clinical or home settings, the device provides intermittent temperature monitoring. It includes a buzzer for alerts and memory storage for 20 measurements. The device aids in clinical decision-making by providing rapid, non-invasive temperature data, potentially benefiting patients through convenient, accessible monitoring.

Clinical Evidence

Clinical testing was conducted per ASTM E 1965-98 Standard Specification for Infrared Thermometers for Intermittent Determination of Patient Temperature. Non-clinical data included biocompatibility (ISO 10993-1, -5, -10), electrical safety (ANSI/AAMI ES60601-1), EMC (IEC 60601-1-2), and performance testing (ISO 80601-2-56). All tests passed, supporting substantial equivalence.

Technological Characteristics

Infrared sensor-based thermometer; forehead and ear measurement modes. Materials: ABS plastic and PE lens filters. Power: 3Vdc battery. Connectivity: None. Display: LCD with 0.1°C/°F resolution. Standards: ANSI/AAMI ES60601-1, IEC 60601-1-2, IEC 60601-1-11, ISO 80601-2-56, ASTM E1965-98.

Indications for Use

Indicated for the measurement and monitoring of human body temperature in patients by clinicians in hospitals or by consumers at home.

Regulatory Classification

Identification

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

#### Justification for the differences:

- 1) Different Indications for Use
As indicated in the comparison table, the subject device can be used both in hospital and home, which the predicate can be used at home only. But the scenario where the device is intended to use require the same performance and clinical requirement considering the usage of such general public device. Moreover, the EFT-16 series Infrared thermometer has been verified and the results show PASS for all test, so the different extra hospital scenario will not introduce any new questions of safety and effectiveness.

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

- 2) Different patient-contacting
The patient-contacting materials of the subject include ABS and PE, and both materials show biocompatible after tested per the international standards ISO10993-5 and ISO 10993-10.

- 3) Different accuracy
The difference accuracy is that the subject shows the accuracy is ±0.2°C(0.4°F) for the whole measurement range, while the accuracy of the predicate is the same when the temperature is 35.5-42.0°C(95.9-107.6°F ) , and minor different accuracy when lower than 35.5°C(95.9°F ) or higher than 42.0°C(107.6°F ). The critical feature meets the requirements of the international standards ISO 80601-2-56:2019 and the FDA recognized specific standard ASTM E 1965-98.

- 4) Different Operating Environment
The subject can operate in a narrower environment condition range than the predicate, while can store in wider environment condition range, but both are minor. More important is that such testing has been verified during the design and development process for the environmental testing, and the results show PASS, so such different will not cause any new safety and effectiveness questions.

- 5) Different Storage Environment
Same explanation as the justification for 4# difference.

- 6) Different Applicable Standards
The difference is that the subject device and the predicate refer to different standard, the former uses the US standard AAMI ANSI ES60601-1, while the predicate uses the international standard IEC60601-1.

- 7) Different Memory Data Limit
The subject can store one more data than the predicate, which is verified during all the testing, and the function shows stable.

As seen in the comparison tables, the subject and predicate devices have similar design features and performance specifications. The main technological differences between the subject and predicate devices are minor differences, including only the appearance, control keys, and operating/storage environment which do not raise different questions of safety or effectiveness. Moreover, as demonstrated in the non-clinical testing, the different technological characteristics do not affect the performance of the EFT-16 series Infrared thermometer system.

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

## 9 Conclusion

Based on the above considerations table, the Proposed Device, the EFT-16 series Infrared thermometer is substantially equivalent to the predicate device Famidoc Infrared thermometer (K113761).
