Intended Use
The Delwa-Star® WS-FM Blood Pressure and Body Fat Monitor is intended for use by adults with moderately active to inactive lifestyles for measuring the systolic and diastolic blood pressure, and pulse rate (heart rate) by using an inflated cuff which is wrapped around the wrist. The device is also intended to estimate body fat by bioelectrical impedance analysis.
Device Description
The Delwa-Star® WS-FM Blood Pressure and Body Fat Monitor uses bioelectrical impedance analysis, a well established technique, for body fat assessment. It measures the systolic and diastolic blood pressure, and pulse rate (heart rate) by use of an inflatable cuff that is wrapped around the wrist, a LCD display, a semiconductor sensor, and internal air pump, a battery power source and keys for operation.

No
The description focuses on standard bioelectrical impedance analysis and blood pressure measurement techniques, with no mention of AI or ML.

No
The device is a monitor intended for measurement and assessment, not for treating or providing therapy for a medical condition.

Yes
The device is described as "measuring the systolic and diastolic blood pressure, and pulse rate (heart rate)" and also "estimate body fat by bioelectrical impedance analysis." These are measurements related to physiological states, indicating that the device provides information for diagnosis or monitoring.

No

The device description explicitly lists hardware components such as an inflatable cuff, LCD display, semiconductor sensor, internal air pump, battery power source, and keys for operation.

Based on the provided information, the Delwa-Star® WS-FM Blood Pressure and Body Fat Monitor 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.
  • Device Function: The Delwa-Star® WS-FM measures blood pressure and pulse rate using a cuff on the wrist (a non-invasive method) and estimates body fat using bioelectrical impedance analysis (also a non-invasive method). These measurements are taken directly from the body, not from a sample taken from the body.
  • Intended Use: The intended use describes measuring physiological parameters (blood pressure, pulse rate, body fat) directly from the user.

Therefore, the device's function and intended use clearly fall outside the scope of in vitro diagnostics.
