Intended Use
The Infrared thermometer is a non-contact infrared thermometer intended for the intermittent measurement of human body temperature from forehead for people of one month old and above. The device is reusable for home use and clinical use.
Device Description
The Infrared Thermometer, Models RN-50A and RN-50B are hand-held device powered by 2*AA batteries and designed to measure human body temperature without contacting patient' forehead. The Infrared Thermometers RN-50A and RN-50B measure the temperature by using the principle of receiving infrared. An object with a temperature higher than absolute zero will radiate a certain amount of infrared energy. According to the infrared energy and wavelength, the surface temperature of the object can be determined. The temperature of human forehead is relatively constant, so the temperature of human forehead can be measured according to this principle. The thermometer adopts a new CMOS compatible thermopile sensor with good sensitivity. The pressure difference generated by the sensor after receiving the infrared signal is amplified and analyzed then display on the LCD screen in digital form. The measurement distance of the subject device is 3~5 cm from the forehead. The only differences among the RN-50A and RN-50B thermometers are size, weight, shape of enclosure.

No
The device description and performance studies focus on standard infrared thermometry principles and clinical validation against a predicate device, with no mention of AI or ML algorithms for temperature measurement or analysis.

No.
The device is an infrared thermometer for measuring body temperature, which is a diagnostic tool, not a therapeutic one. It does not provide treatment or alleviate symptoms.

No

The device is an infrared thermometer for measuring body temperature, which is a measurement device, not a diagnostic device that identifies diseases or conditions.

No

The device description explicitly states it is a hand-held device powered by batteries and uses a thermopile sensor to receive infrared signals, indicating it is a hardware device with embedded software, not a software-only medical device.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information about a person's health. This testing is done outside of the body (in vitro).
  • This Device's Function: The Infrared Thermometer measures human body temperature directly from the forehead. It does not analyze any specimens taken from the body. It is a non-invasive measurement of a physiological parameter.

Therefore, based on the provided information, the Infrared Thermometer is a medical device, but it falls under a different category than In Vitro Diagnostics.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Clinical tests were conducted per ASTM E1965-98(Reapproved 2016) Standard Specification for Infrared Thermometers for Intermittent Determination of Patient Temperature. This clinical study is a randomization, simple blind homologous control, pairing design of clinical investigation, consists of a 161 subjects which were divided into three group age ranges- A Infant group (Group A- (A1) 1 month up to 3 months; (A2)- 3 months up to 1 year), B Child group (greater than 1 to 5 years old) and C Over 5 years old (Above 5 years old). Each group at least has 35 subjects.

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

Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)

Accuracy: Forehead mode: ±0.2°C (0.4°F) within 36.0°C ~ 39.0°C (96.8°F ~ 102.2°F), ±0.3°C(0.5°F) other range

Analysis:

From the comparison table, the subject devices and predicate device have the same Intended use & Indications for Use, Measurement place, Display resolution, Display screen, Auto power-off while no operation and Conformance standard. There are slightly differences between the devices and predicate device as follows:

Different 1:The restriction in use for people of one month old and above, that is the subset patient population of the predicate device, thus no new safety and effectiveness concerns raised due to the difference.

Different 2: Both devices have different measurement range, but they have the same accuracy and the measurement range of subject devices meet the requirements of ASTME1965-98. The difference does not raise new performance questions.

Different 3: Measurement distance of the subject devices is 3-5cm, the predicate device's will be ≤3cm. Although the "measurement distance" of subject device is a little different from the predicate devices. The clinical trial

report of the subject device demonstrates the device meets the clinical accuracy requirements of the standards ISO 80601-2-56 and ASTM E1965-98 within the distance range, the differences between the predicate device and subject device will not affect the safety and effectiveness of the subject device.

Different 4: Both devices have slightly different Operation &Storage Environment, but the subject devices meet the requirements of IEC60601-1 and 80601-2-56.

In conclusion, these differences do not raise any new safety or performance questions.

Software validation was conducted in accordance with a moderate level of concern designation in accordance with the FDA November 2005 document "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices"

9.0 Clinical Accuracy Validation Test Conclusion

Clinical tests were conducted per ASTM E1965-98(Reapproved 2016) Standard Specification for Infrared Thermometers for Intermittent Determination of Patient Temperature. This clinical study is a randomization, simple blind homologous control, pairing design of clinical investigation, consists of a 161 subjects which were divided into three group age

ranges- A Infant group (Group A- (A1) 1 month up to 3 months; (A2)- 3 months up to 1 year), B Child group (greater than 1 to 5 years old) and C Over 5 years old (Above 5 years old). Each group at least has 35 subjects.

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

10.0 Conclusion

Performance testing contained in this submission demonstrates the minor differences in technological characteristics between the subject device and the predicate do not raise different questions of safety and effectiveness. And based on the performance testing and compliance with acceptable voluntary standards, we believe the Infrared Thermometer RN-50A and RN-50B are substantially equivalent to its predicate device in K191251.
