Intended Use
Fudakang Digital Thermometers are intended for the measurement and monitoring of human body temperature by doctor or consumers in the hospital or home. BT-A11CN, BT-A21CN, BT-A41CN can be used for axillary measurement, oral measurement and rectal measurement.
Device Description
Fudakang digital thermometers are hand-held, reusable, battery operated. The models include BT-A11CN, BT-A21CN, and BT-A41CN. All the models have the same indication for use. The difference points are their shapes, colors, voice function, and measurement speed. The operation principle is based on thermosensor and ASIC technology. A thermistor is used as thermosensor. The ASIC gets the sensor's signal from human body, then processes the signal and calculates the result, after that displays the temperature result by a LCD. The digital thermometer comprises a thermistor for getting temperature signal, a reference resistor for comparing the resistance of the thermistor, a buzzer for sounding effect, an ASIC for processing the target temperature digitally, and a LCD for displaying the temperature result.
More Information

No
The device description explicitly states the operation principle is based on thermosensor and ASIC technology, processing signals and calculating results without mentioning AI or ML.

No
The device is described as a digital thermometer for measuring and monitoring human body temperature, which is a diagnostic function, not a therapeutic one.

No

A thermometer measures body temperature, which is a symptom. It does not provide a diagnosis of a disease or condition. The "Intended Use" states it's for "measurement and monitoring of human body temperature," which is a vital sign, not a diagnostic finding.

No

The device description explicitly states it is a hand-held, reusable, battery-operated device comprising hardware components like a thermistor, ASIC, buzzer, and LCD.

Based on the provided information, 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 Fudakang Digital Thermometer measures human body temperature directly from the body (axillary, oral, rectal). It does not analyze samples taken from the body.
  • Intended Use: The intended use is for "measurement and monitoring of human body temperature," which is a direct physiological measurement, not an in vitro test.

Therefore, the Fudakang Digital Thermometer falls under the category of a medical device for physiological measurement, not an in vitro diagnostic device.
