# Note 1

The subject device is used for ages 12 months and older. However, the predicate is used for infants and adults. The user population of the subject device is subset of the predicate. And the manufacturer had conducted clinical accuracy trial to verify measurement accuracy for declared patient population according to ISO 80601-2-56. Therefore, this difference does not raise new safety and effectiveness questions.

# Note 2

Measurement distance of the subject devices is 3-5cm, the predicate device's will be in the range of 1-6cm. And the manufacturer had conducted clinical accuracy trial to verify measurement accuracy for declared patient population according to ISO 80601-2-56 based on the measurement distance 3-5 cm. The performance test result of subject device shows the accuracy meets the requirements within the distance range. Therefore, this difference does not raise new safety and effectiveness questions.

## Note 3

The subject devices and predicate device have different measurement range and different laboratory accuracy specification, but the laboratory accuracy and the measurement range of subject devices meet the requirements of ASTME1965-98. And clinical accuracy also had been validated according to ISO 80601-2-56. Therefore, the difference does not raise new safety and effectiveness questions.

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

# Note 4

The memory capacity of predicate device is different from subject devices, but the memory function does not affect accuracy of measurement and does not impact the performance of subject devices.

# Note 5

There is minor difference on the temperature operation condition between predicate device and subject device. But the subject device also had pass IEC60601-1-11 and the labelling will indicate the operation condition. Therefore, this difference does not impact of safety and effectiveness.

# Note 6

There is minor difference on the size and weight between predicate device and subject device. But this difference does not impact of safety and effectiveness.

# Note 7

There is minor difference on the material of device case and enclosure between predicate device and subject device. But the operator or patient contacting parts' in the subject device all complied with ISO 10993-5, ISO 10993-10. Therefore, the difference would not cause issue of safety and effectiveness.

# 9. Summary of Clinical Test

Clinical study for non-contact thermometer was performed to determine the clinical accuracy and to provide comparison with predicate device. The study excluded subjects with medical conditions such as inflammation at the measuring sites and subjects using medications known to affect body temperature.

The clinical tests evaluated 100 subjects which were divided into two group age ranges- children (1 to 5 years old) and adult (greater than 5 years old). The clinical accuracy of the proposed device was evaluated by ISO 80601-2-56 - clinical bias with stated uncertainty and clinical repeatability. The clinical test results showed that the accuracy of the proposed device is within acceptable scope specified in ISO 81061-2-56.

Based on the result, the clinical performance of the subject device complied with the requirement of ASTM E1965-98 (2016).

## 10. Conclusion

Based on the performance testing, comparison and analysis provided it was concluded that the subject device Medical infrared forehead thermometer (Model: HG01, HG01 V1,HG06) is substantially equivalent to the cleared predicate Non-contact Forehead Thermometer (K131243) Model JPD-FR100.
