No
The description focuses on standard infrared sensing and basic electronic processing (signal sampling, AD conversion, threshold processing, power management, user interface). There is no mention of AI, ML, or complex algorithms that would typically indicate their use. The clinical trial methodology also aligns with standard thermometer validation, not AI/ML model performance evaluation.

No.
The device is used to detect human body temperature, which is a diagnostic function, not a therapeutic one. It provides information for monitoring but does not directly treat or alleviate a medical condition.

No

This device is described as an electronic thermometer for detecting human body temperature, which is a measurement tool rather than a diagnostic tool. While temperature can be a symptom, the device itself doesn't provide a diagnosis. The "Prompt for fever" feature might indicate a temperature above a threshold, but it still falls short of a medical diagnosis.

No

The device description explicitly mentions an "infrared sensor" and describes physical features like "One-key measurement" and "Automatically power-off," indicating it is a hardware device with embedded software, not a software-only medical device.

Based on the provided information, this device is not an In Vitro Diagnostic (IVD).

Here's why:

  • IVDs analyze samples taken from the human body. The definition of an IVD involves examining specimens such as blood, urine, tissue, etc., outside of the body to provide information about a person's health.
  • This device measures a physical parameter on the human body. The infrared thermometer directly measures the temperature from the ear canal, which is a physical measurement taken in vivo (on the living body), not an analysis of a sample in vitro (in glass/outside the body).

The device is a medical device, specifically a thermometer, but it does not fit the definition of an In Vitro Diagnostic.
