No
The description focuses on the device's predictive technology based on thermistor resistance and R-C oscillator circuits, which is a traditional method for temperature measurement and prediction, not AI/ML. There is no mention of AI, ML, or related concepts in the document.
No
The device is used for measuring body temperature, which is a diagnostic function, not a therapeutic one. It does not treat or alleviate any condition.
Yes
Explanation: The device is described as being used for "measurement and monitoring of human body temperature," which is a diagnostic function.
No
The device description clearly outlines a hardware-based thermometer utilizing a thermistor and R-C oscillator circuit to measure temperature. It is a physical, hand-held device.
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 these samples outside of the body.
- Device Function: The Microlife QT1JC1 Instant Thermometer measures human body temperature directly from the body (orally, rectally, under the arm). It does not analyze samples taken from the body.
Therefore, based on the provided information, the Microlife QT1JC1 Instant Thermometer is a clinical thermometer, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
Microlife QT1JC1 Instant Thermometer is used for the intermittent measurement and monitoring of human body temperature, orally, rectally and under the arm.
The Microlife QT1JC1 Instant Thermometer is a hand- held, non-sterile, reusable clinical thermometer intended for the determination of human temperature in either predictive ( Instant ) mode ( 5-seconds in oral and rectal mode, 8-seconds in under the arm mode-predicative temperature } , or standard mode ( actual determination of temperature).
The device is for the adult and pediatric population.

Device Description
This Instant thermometer enables very fast and reliable measurements and with its predicative technology the thermometer offers a very high clinical accuracy and has been designed to provide a maximum of user- friendliness
The basic principle of this thermometer is that change of thermistor resistance, caused by changes of temperature, are converted to changes of frequency of R-C oscillator circuit, Therefore, temperature can be given by measuring the frequency of oscillator.
For a give time period (to), by applying to R-C oscillator circuit, changes of temperature will correspond to changes of pulse number

§ 880.2910 Clinical electronic thermometer.
(a)
Identification. A clinical electronic thermometer is a device used to measure the body temperature of a patient by means of a transducer coupled with an electronic signal amplification, conditioning, and display unit. The transducer may be in a detachable probe with or without a disposable cover.(b)
Classification. Class II (performance standards). The device is exempt from the premarket notification procedures in part 807, subpart E of this chapter, subject to the limitations in § 880.9 and the following conditions for exemption:(1) Device is not a clinical thermometer with telethermographic functions;
(2) Device is not a clinical thermometer with continuous temperature measurement functions; and
(3) Appropriate analysis and testing (such as that outlined in the currently FDA-recognized editions, as appropriate, of ISO 80601-2-56, “Medical electrical equipment—Part 2-56: Particular requirements for basic safety and essential performance of clinical thermometers for body temperature measurement,” or ASTM E1965, “Standard Specification for Infrared Thermometers for Intermittent Determination of Patient Temperature,” or ASTM E1112, “Standard Specification for Electronic Thermometer for Intermittent Determination of Patient Temperature,” or ASTM E1104, “Standard Specification for Clinical Thermometer Probe Covers and Sheaths”) must validate specifications and performance of the device.
