The device description explicitly states that the calculation is performed by an ASIC-controlled circuit, which is described as "hard-wire control instead of programmable control." There are no mentions of AI, ML, or related concepts.
No.
The device is solely for measurement and diagnosis, not for treating any condition.
Yes
The device measures body temperature, which is a physiological parameter used to identify or monitor a medical condition, making it a diagnostic device.
No
The device description explicitly details hardware components such as a thermistor, reference resistor, buzzer, ASIC, and LCD, and describes a hand shaking power generation mechanism. It is a physical device with embedded electronics, not software only.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to measure body temperature. This is a physiological measurement taken directly from the patient's body (oral, axillary, rectal).
- Device Description: The device uses a thermistor to measure temperature and displays the result. This is a direct measurement of a physical parameter.
- Lack of In Vitro Activity: IVD devices are designed to examine specimens derived from the human body (like blood, urine, tissue) in vitro (outside the body) to provide information about a physiological state, health, or disease. This device does not perform any analysis on such specimens.
Therefore, this device falls under the category of a clinical thermometer, which is a medical device but not an IVD.
N/A
Intended Use / Indications for Use
The device measures the body temperature of a patient by means of a sensor (transducer) coupled with electronic signal amplification, conditioning and digital LCD (display) unit. The device is reusable and intended for oral, axillary or rectal temperature measurements.

Device Description
The shaker digital thermometer, model ST8S Series, are the electronic thermometers by using a thermistor as the temperature sensor. The signal of sensor is calculated and displayed by an ASIC (Application Specific IC) - controlled circuit, which is considered the hard-wire control instead of programmable control.
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.
ST8S uses a hand shaking power generation mechanism to generate the electrical power required for short time temperature measurement operation. Whenever the generated power is low, the device as well as LCD display are switched off automatically. Regarding the performance of ST8S Series, it was designed and verified according to the US standard ASTM E 1112-00.
