Intended Use
The device is a noninvasive blood pressure measurement system intended to measure the systolic and diastolic blood pressures and pulse rate of an adult individual, over age 18, at home by using a non-invasive technique in which an inflatable cuff is wrapped around the wrist. The cuff circumference is limited to be 5.25" – 7.75".
Device Description
FORTIFIER Digital Wrist Blood Pressure Monitor, LF-01 uses the Oscillometric method to measure the blood pressure. The Oscillometric method is adopted clinically to measure the blood pressure recently. It is not needed to use the stethoscope, as in the traditional measuring method, to monitor the Korotkov sound when deciding the systolic or diastolic pressure. The Oscillometric method senses the vibrating signal via the closed air pipe system and utilizes the microcomputer to automatically sense the characteristics of the pulse signal. Through simple calculation, clinically proven, the reading can reflect the accurate real blood pressure, and the systolic pressure is defined as the pressure when the cuff pressure oscillating amplitude begins to increase and the diastolic pressure as the pressure when the cuff pressure oscillating amplitude stops decreasing.
More Information

No
The description details the use of the Oscillometric method and a microcomputer for signal processing and calculation, which are standard techniques for digital blood pressure monitors and do not inherently indicate the use of AI/ML. There are no mentions of AI, ML, or related concepts like training/test sets.

No.
The device is strictly for measurement and monitoring of blood pressure and pulse rate, not for treatment or therapy.

Yes

The device measures systolic and diastolic blood pressure and pulse rate, which are physiological parameters used to assess a person's health status and can indicate the presence of certain medical conditions. This function aligns with the definition of a diagnostic device.

No

The device description explicitly mentions an "inflatable cuff" and the use of the "Oscillometric method" which involves sensing vibrating signals via a "closed air pipe system." These are hardware components and physical measurement techniques, indicating it is not a software-only device.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
  • Device Function: The description clearly states the device is a "noninvasive blood pressure measurement system" that measures blood pressure and pulse rate by wrapping an inflatable cuff around the wrist. This is a direct measurement of a physiological parameter from the body's surface, not an analysis of a specimen taken from the body.
  • Method: The device uses the "Oscillometric method," which senses vibrations through a closed air pipe system. This is a physical measurement technique, not a chemical or biological analysis of a sample.

The device is a non-invasive physiological monitoring device, not an in vitro diagnostic device.
