The description focuses on the oscillometric method and standard signal analysis techniques for blood pressure and pulse rate. While it detects atrial fibrillation, the mechanism described doesn't explicitly mention or imply the use of AI/ML. The performance studies and predicate devices also do not suggest AI/ML is involved.
No
This device is a diagnostic device used for measuring blood pressure and detecting atrial fibrillation, not a therapeutic device that treats a condition.
Yes.
The device is intended to measure and detect atrial fibrillation, which are diagnostic purposes.
No
The device description explicitly mentions physical components like inflatable cuffs, resistive pressure sensors, and electrical signals, indicating it is a hardware device with integrated software, 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 tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The Microlife WatchBP Office AFIB measures blood pressure and detects atrial fibrillation using a non-invasive oscillometric technique applied to the upper arm. It does not analyze samples taken from the body.
- Intended Use: The intended use clearly states it measures physiological parameters (blood pressure, pulse rate, etc.) of an individual using a cuff on the arm.
- Device Description: The description reinforces the non-invasive nature of the measurement using pressure sensors and the oscillometric method.
Therefore, this device falls under the category of a non-invasive medical device for physiological monitoring, not an in vitro diagnostic device.

Device Description
Microlife Upper Arm Automatic Digital Blood Pressure Monitor, Model WatchBP Office AFIB (TWIN200 AFS) is designed to measure systolic and diastolic blood pressure, pulse rate, pulse pressure (PP) and mean arterial pressure (MAP) of an individual by using a non-invasive technique in which one (or two) inflatable cuff(s) is (are) wrapped around the single (or dual) upper arm(s). Our method to define systolic and diastolic pressure is similar to the auscultatory method but use two resistive pressure sensors rather than a stethoscope and mercury manometer. The sensors convert tiny alterations in cuff pressure to electrical signals, by analyzing those signals to define the systolic and diastolic blood pressure and calculating pulse rate, pulse pressure (PP) and mean arterial pressure (MAP), which is a well known technique in the market called the "oscillometric method".
The device has >, > and > measurement modes and has atrial fibrillation detection function, inflation pressure setting function, measurement intervals setting function etc.
The > mode is selected for blood pressure measurement of patients to confirm if a patient is suitable for the oscillometric method.
The > mode is selected to complete a fully-automated triple measurements on both arms according to recommended ESH/AHA blood pressure measurement protocols for a patient's first office visit.
The > mode is selected to perform an automated duplicate measurements on the preferred arm for prompt and accurate office measurements.

5. Intended Use:
The Microlife Upper Arm Automatic Digital Blood Pressure Monitor, Model WatchBP Office AFIB (TWIN200 AFS) is a device intended to measure the systolic and diastolic blood pressure, pulse pressure (PP) and mean arterial pressure (MAP) of an adult individual by using a non-invasive oscillometric technique in one (or two) inflatable cuff(s) is (are) wrapped around the single (or dual) upper arm(s).
The device detects the appearance of atrial fibrillation during measurement and gives a warning signal with the reading once the atrial fibrillation is detected.
Comparison to the 510(k) Cleared Device (Predicate Device): 6.
The subject modified device, Model WatchBP Office AFIB (TWIN200 AFS) and our predicate device, Model WatchBP Office (Twin200), use the well-known oscillometric method within the software algorithm to determine the systolic and diastolic blood pressure and pulse rate. Upper arm cuff(s) is (are) inflated automatically, deflation rate is controlled by one (or two) factory set exhaust valve(s) and the deflation pressures are transferred via tubing to one (or two) sensor(s).
The sole differences between the two models are the measurement mode names, sensor type and additional features such as atrial fibrillation detection function. However, the differences do not affect the accuracy and normal use of this device.
The atrial fibrillation detection function is the same with what is used in our predicate device Model BP3MQ1-2D, 510(k) cleared under K080337.
