No
The summary describes a standard oscillometric blood pressure monitor and does not mention any AI or ML components or capabilities.

No
The device measures blood pressure and heart rate, which is a diagnostic function, not a therapeutic one. It does not treat or prevent any specific disease or condition.

Yes
Explanation: The device measures systolic and diastolic blood pressure and heart rate, which are used to assess a patient's health status and identify potential medical conditions, thus making it a diagnostic device.

No

The device description explicitly states "Rossmax Automatic Wristwatch Blood Pressure Monitor, model Z40," which indicates a hardware device (a wristwatch blood pressure monitor) and not a software-only medical device.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or treatment.
  • This device measures blood pressure and heart rate directly on the wrist using the oscillometric method. This is a non-invasive measurement taken from the body itself, not from a specimen derived from the body.

Therefore, based on the provided information, the Rossmax Automatic Wristwatch Blood Pressure Monitor, model Z40, is a non-IVD medical device.
