The device description details a standard infrared temperature measurement process involving a sensor, signal amplification, AD conversion, and calculation by a microcontroller (MCU). There is no mention of AI, ML, or any learning algorithms used for temperature determination or interpretation. The performance studies focus on clinical accuracy against a reference standard, not on validating an AI/ML model.
No
The device is an infrared body thermometer used for measuring temperature, which is a diagnostic tool, not a therapeutic one. It does not treat or alleviate any condition.
Yes
Explanation: The device measures human body temperature, which is a physiological parameter used to assess health status and identify conditions like fever, thus contributing to diagnosis.
No
The device description explicitly states it is a "hand-held, reusable, battery powered device" that includes a "temperature sensor" and an "LCD display screen," indicating it is a physical hardware device, not software only.
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.
- Device function: The INFRARED BODY THERMOMETER (Model: YK-001) measures human body temperature by detecting infrared energy radiated from the forehead. This is a non-invasive measurement taken directly from the body surface.
- No sample analysis: The device does not analyze any biological samples taken from the patient.
Therefore, based on the provided information, the device is a medical device used for measuring body temperature, but it does not fit the definition of an In Vitro Diagnostic.

Device Description
The proposed device, INFRARED BODY THERMOMETER, which includes model YK-001 hand-held, reusable, battery powered device, which is intended to detect body temperature from forehead. The proposed device measure temperatures of people by detecting the infrared energy radiated directly from the forehead without physical contact. The distance of the measurement is 3cm~5cm. The proposed device uses a temperature sensor, which can detect the human forehead temperature, object temperature and environment temperature; these temperatures are then transfer to electronic signal and amplified; and then it is transferred to digital signal by AD module in MCU of the proposed device. MCU will calculate the body temperature, and then transfer to screen for display. The device has the following features: About two-second measuring time, measuring Body or Ambient temperature, 99-memory recalls, °C/°F unit switchable, over range message (Hi/Lo), low battery indication, auto shut-off when the device is idle for 15 seconds. When completes, the results will be displayed on the LCD display screen. The device will display 3 different background colors according to the result.
The power supply of INFRARED BODY THERMOMETER (YK-001) is 3.0V DC, it is powered by two AAA batteries.
The reference body site of INFRARED BODY THERMOMETER (Model: YK-001) is armpit.

Description of the test set, sample size, data source, and annotation protocol
The clinical accuracy study for the non-contact thermometer was performed to determine the clinical accuracy. The three groups of subjects being tested were: 1) over 1 month to under 1 year old, 2) children between 1 and 5 years old, and 3) patients over 5 years old.
The study includes 137 subjects. For each age group, the ratio of febrile subjects was more than 30% and less than 50%. 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 test results showed that the accuracy of the proposed device is within acceptable scope specified in ISO 81061-2-56.
