The description focuses on standard oscillometric blood pressure measurement and irregular heartbeat detection using a well-known technique. There is no mention of AI, ML, or any related concepts in the device description, intended use, or performance studies.
No
The device is intended to measure blood pressure and pulse rate, and detect irregular heartbeats, but it does not provide any treatment or therapy.
Yes
The device measures systolic and diastolic blood pressure and pulse rate, and also detects irregular heartbeats, which are all indicators of a diagnostic function.
No
The device description clearly states it is a "Microlife Wrist Watch Blood Pressure Monitor" that uses an inflatable cuff and a capacitor pressure sensor, indicating it is a hardware device with integrated software. While it connects to PC software, the core medical device is the physical blood pressure monitor.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information about a person's health.
- Device Function: The Microlife Wrist Watch Blood Pressure Monitor, Model BP3NU1-4X, measures blood pressure and pulse rate non-invasively by using a cuff wrapped around the wrist. It does not analyze any specimens taken from the body.
- Intended Use: The intended use is to measure physiological parameters (blood pressure and pulse rate) directly from the individual, not to analyze samples.
Therefore, based on the provided information, this device falls under the category of a non-invasive physiological monitoring device, not an In Vitro Diagnostic device.

Device Description
Microlife Wrist Watch Blood Pressure Monitor, Model BP3NU1-4X is designed to measure systolic and diastolic blood pressure and pulse rate of an individual by using a non-invasive technique in which an inflatable cuff is wrapped around the wrist. Our method to define systolic and diastolic pressure is similar to the auscultatory method but uses a capacitor pressure sensor rather than a stethoscope and mercury manometer. The sensor converts tiny alterations in cuff pressure to electrical signals, by analyzing those signals to define the systolic and diastolic blood pressure and calculating pulse rate, which is a well - known technique in the market called the "oscillometric method".
The device has Irregular Heartbeat Detection (IHD) function. It detects the appearance of irreqular heartbeat during measurement and the irreqular heart beat symbol " is displayed on the LCD screen if any irregular heart beat signal has been detected. In addition, the device can be used in connection with your personal computer (PC) running the Microlife Blood Pressure Analyzer (BPA) software. The memory data can be transferred to the PC by connecting the monitor with the PC via USB cable.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The subject device Model BP3NU1-4X is from the technical point of view, identical to the predicate blood pressure monitor. Moreover, the measurement algorithm and its program codes of BP3BS1-3C remain unchanged. The fundamental scientific technology of the modified BP3BS1-3C device is the same as the predicate device BP3NU1-4X. Therefore the performance of the BP3NU1-4X in terms of blood pressure measurement would be identical with performance of the predicate device BP3BS1-3C. Repeat clinical testing in accordance with the standard ANSI/AAMI SP10 for the subject device BP3NU1-4X is therefore not necessary as clinical testing results were not affected by the changes to the subject modified device.

6. Comparison to the 510(k) Cleared Devices (Predicate Devices):
The subject BP3NU1-4X and the predicate device model BP3BS1-3C, use the same oscillometric method with the same fundamental scientific technology to determine the systolic and diastolic blood pressure and pulse rate. Wrist cuff is inflated automatically by pump and the pressures are transferred via tubing to a sensor in these two units.
They differ by the traffic light function, Blood Pressure Analyzer Software version, and MAM function. The traffic light function and MAM function are added to the subject device. But those differences do not affect the accuracy and normal use of this device because they use the same fundamental scientific technology . Therefore repeated clinical test in accordance with the standard ANSI/AAMI SP10 is not necessary, please refer to "Clinical Declaration of Identity" in EXHIBIT #9a.
The subject BP3NU1-4X and the predicate BP3MO1-3P both has traffic light function. And the traffic light function has no impact on the clinical accuracy in terms of blood pressure detection.
7. Discussion of Non-Clinical Tests Performed for Determination of Substantial Equivalence are as follows:
Testing information demonstrating safety and effectiveness of the Microlife Wrist Watch Blood Pressure Monitor, Model BP3NU1-4X in the intended environment of use is supported by testing that was conducted in accordance with the FDA November 1993 Draft "Reviewer Guidance for Premarket Notification Submissions". DCRND, which outlines Electrical, Mechanical and Environmental Performance requirements.
5
The following testing was conducted:
- a. Reliability Test Storage test
- b. Reliability Test Operating test
- c. Reliability Test Vibration test
- d. Reliability Test Drop test
- e. Reliability Test Life test
- EMC Test ﺖ
None of the testing demonstrated any design characteristics that violated the requirements of the Reviewer Guidance or resulted in any safety hazards. It was our conclusion that Microlife Wrist Watch Blood Pressure Monitor, Model BP3NU1-4X tested met all relevant requirements of the aforementioned tests.
8. Discussion of Clinical Tests Performed:
The subject device Model BP3NU1-4X is from the technical point of view, identical to the predicate blood pressure monitor. Moreover, the measurement algorithm and its program codes of BP3BS1-3C remain unchanged. The fundamental scientific technology of the modified BP3BS1-3C device is the same as the predicate device BP3NU1-4X. Therefore the performance of the BP3NU1-4X in terms of blood pressure measurement would be identical with performance of the predicate device BP3BS1-3C. Repeat clinical testing in accordance with the standard ANSI/AAMI SP10 for the subject device BP3NU1-4X is therefore not necessary as clinical testing results were not affected by the changes to the subject modified device.
9. Software information:
Software validation was conducted in accordance with a moderate level of concern designation in accordance with the FDA November 2005 document "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices".
10. Conclusions:
We have demonstrated that there are no significant differences between the Microlife Wrist Watch Blood Pressure Monitor, Model BP3NU1-4X and the predicate devices, Model BP3BS1-3C and Model BP3MO1-3P, in terms of safety and effectiveness based on electrical, mechanical and environmental test results per the FDA DCRND November 1993 Draft "Reviewer Guidance for Premarket Notification Submissions", and the ANSI/AAMI Voluntary Standard, SP10: 2008, AAMI / ANSI / IEC 80601-2-30:2009.
