The description focuses on standard infrared temperature measurement technology and does not mention any AI or ML components.
No
An infrared thermometer is designed to measure human body temperature, which is a diagnostic function, not a therapeutic one. It does not treat or alleviate any condition.
Yes
Explanation: The device is designed for "measuring human body temperature" which is a physiological parameter used to diagnose conditions like fever. While it doesn't directly diagnose a disease, it provides data essential for medical diagnosis.
No
The device description explicitly states it is comprised of hardware components such as infrared temperature sensors, signal receiving processor, buttons, buzzer, LCD display, and battery. It also mentions focusing infrared light with a Fresnel lens.
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 to examine specimens outside of the body.
- Device Function: The description clearly states that this device measures human body temperature by receiving infrared energy radiation from the surface of the body (ear or forehead). This is a measurement taken directly from the body, not from a sample taken from the body.
Therefore, based on the intended use and device description, this infrared thermometer is a medical device used for direct physiological measurement, not an in vitro diagnostic device.

Justification for the differences:
- Different Indications for Use and Intended patient population
The predicate and subject device share similar indications for use as shown in their labeling, and the difference is the subject is for people of all ages except neonates/newborns, while the predicate can only be used for people over three months. This difference has been verified by internal verification and an external clinical accuracy study, so this difference will not cause any safety or effectiveness problem.
2) Different Measuring Distance for forehead mode
The predicate device is contacting type for forehead mode, but the subject device is non-contact type. The software and hardware for the subject device is verified to be supportive of the safety and performance declared in the labeling, which will not cause any safety or effectiveness problem.
3) Different Operating/Transport conditions
Minor difference to operation/transport environment for the subject device, but the system has been
7
proven to be safe and effective based on the safety testing conducted under the suggested environment. Environment testing data shows the device can function as intended under the suggested conditions. So those changes will not cause any safety or effectiveness problem.
- Different Memory Data Limit
The subject KFT series thermometer can store 10 sets of data less than the predicate, which is verified through device testing.
-
- Different Patient contact material
The patient contacting materials of the predicate and the subject devices are ABS+PE and ABS, respectively. Both are compliant with international standards ISO 10993-5/ISO10993-10, and the corresponding test reports provided demonstrate material safety.
- Different Patient contact material
-
- Different Physical Dimension and weight
The dimension and weight of the subject device are different from the predicate device. The physical characteristics differences have been verified during the design and development and will not raise any safety or effectiveness problem .
- Different Physical Dimension and weight
- Different display screen and Sound from the device with successful measurement The predicate and subject device differs in nonessential characteristics. The differences have been verified before product release, including hardware and software. No safety or effectiveness problem observed.
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 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 safety and effectiveness of the KFT series Infrared thermometer system.
8. Performance Data
Performance data includes "Non-Clinical Data" and "Clinical Data", brief description of which are shown as below.
Non-Clinical Data:
The following performance data were provided in support of the substantial equivalence determination.
Biocompatibility testing
The biocompatibility evaluation for the KFT series Infrared thermometer were conducted in accordance with the International Standard ISO 10993-1 "Biological Evaluation of Medical Devices -Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA.
The worst case of the whole system is considered tissue contacting for duration of less than 24 hours. The testing necessary for this contact category include Cytotoxicity, Skin Sensitization and Irritation per the Annex A Biological evaluation tests of ISO 10993-1, which have been conducted on the IT series Infrared thermometer device.
8
Electrical safety and electromagnetic compatibility (EMC)
Electrical safety and EMC testing were conducted on the KFT series Infrared thermometer device, consisting of all the modules and accessories in the system. The system complies with the ANSI/AAMI ES60601-1:2005/(R)2012and A1:2012, C1:2009/(R)2012 and A2:2010/(R)2012 Medical electrical equipment Part 1: General requirements for basic safety and essential performance for safety and the IEC 60601-1-2: 2014 Medical electrical equipment-Part 1-2: General requirements for basic safety and essential performance - Collateral Standard: Electromagnetic disturbances -Requirements and tests standard for EMC.
Bench Testing
Bench testing was conducted on the KFT series Infrared thermometer device, consisting of all the accessories in the system. The system complies with the IEC 60601-1-11: 2015 MEDICAL ELECTRICAL EQUIPMENT -Part 1-11: General requirements for basic safety and essential performance -Collateral Standard: Requirements for medical electrical equipment and medical electrical systems used in the home healthcare environment, ISO 80601-2-56: 2009 Medical electrical equipment - Part 2-56: Particular requirements for basic safety and essential performance of clinical thermometers for body temperature measurement standards for performance effectiveness.
Software Verification and Validation Testing
Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "Moderate" level of concern, since a failure or latent flaw in the software could directly result in serious injury or death to the patient or operator.
Clinical data:
Clinical testing is conducted per ISO 80601-2-56 Clause 201.102 Clinical Accuracy Validation, where 116 patients are included in the testing, and with grouping shown below. Both forehead and ear measurement modes are evaluated with accuracy results.
| Age | Number of tested group | Febrile/ Non-febrile |
|---|---|---|
| 1~3 month | 17 | 6/11 |
| 3 months ~1 year | 25 | 12/13 |
| 1~5 years | 38 | 17/21 |
| Above 5 years | 36 | 13/23 |
Summary
Based on the non-clinical and clinical performance as documented in the device development, the subject devices were found to have a performance that is similar to the predicate device.
9. Conclusion
9
Based on the above considerations table, the Proposed Device, the KFT series Infrared thermometer is substantially equivalent to the predicate device EFT-16 series Infrared thermometer (K171214).
