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.

Intended Use / Indications for Use
To measure systolic and diastolic blood pressure and heart rate on the wrist using the oscillometric method. Limited to patient over 18 years and wrist circumference between 5.3 to 7.7 inches.
