The device description explicitly states that an ASIC (Application Specific IC) is used for calculation and display, indicating a fixed, non-programmable control system, which is not characteristic of AI/ML. The document also explicitly states "Not Found" for mentions of AI, DNN, or ML, and descriptions of training/test sets, which are typically associated with AI/ML development.
No
The device is a digital thermometer, intended for measuring human body temperature, not for treating any condition.
No
The device is a digital thermometer intended for measuring human body temperature, which is a measurement function, not a diagnostic one. While temperature can be a symptom, the device itself doesn't interpret or diagnose a condition.
No
The device description explicitly details hardware components such as a thermistor, reference resistor, buzzer, ASIC, LCD, and battery. It is an electronic device, not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to measure human body temperature. This is a direct measurement of a physiological parameter within the body, not an analysis of a sample taken from the body (like blood, urine, or tissue).
- Device Description: The description details the components used to measure temperature directly from the body (thermistor, ASIC, LCD). There is no mention of analyzing biological samples.
- Lack of IVD Characteristics: IVD devices typically involve:
- Analyzing samples (blood, urine, tissue, etc.).
- Detecting or measuring substances within those samples (analytes).
- Providing information for diagnosis, monitoring, or screening of diseases or conditions.
This digital thermometer simply measures a physical property (temperature) of the human body.

Device Description
The Digital Thermometers, models MT-XX8 and MT-XX9, are the electronic themometers using a thermistor as the temperature sensor. The signal of sensor is calculated and displayed by an ASIC (Application Specific Integrated Circuit) control instead of programmable control. Basically MT-XX8 and MT-XX9 have the same control with the exception of the different measuring range caused by some small different design in IC circuit.
From the construction point of view, the digital thermometer comprises of a thermistor for measuring sensor, a reference resistor for comparison of temperature, a buzzer for sounding effect, an ASIC for calculating, and LCD for displaying the measuring temperature digitally for which the thermistor contacts.
This system uses a 1.5V DC battery for operation of complete system whenever the battery is low, the ASIC circuit will detect the low battery condition automatically, and displays 'Low battery' in LCD display. Regarding the performance of MT-XX8 and MT-XX9, it was designed and verified according to the US standard ASTM E1112-98.
