No
The description focuses on the oscillometric method and standard signal analysis for blood pressure and pulse rate measurement, with no mention of AI or ML algorithms. The Irregular Heartbeat Detection is described as detecting "irregular heart beat signal," which is a common signal processing technique, not necessarily AI/ML.
No
The device is a blood pressure monitor intended for measurement and detection, not for therapy or treatment.
Yes
The device measures blood pressure and pulse rate, which are physiological parameters used to assess a patient's health status. It also detects irregular heartbeats, which can be indicative of underlying medical conditions. These functions align with the definition of a diagnostic device, as they provide information to aid in the diagnosis or detection of a disease or health problem.
No
The device description explicitly mentions an "inflatable cuff," a "semiconductor sensor," and an "LCD screen," which are all hardware components. The device uses an oscillometric technique involving physical interaction with the patient's wrist via a cuff.
Based on the provided text, 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 description clearly states that this device measures blood pressure and pulse rate using a non-invasive oscillometric technique by wrapping a cuff around the wrist. It does not analyze any samples 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 perform tests on in vitro samples.
Therefore, the Wrist Watch Blood Pressure Monitor, Model BP3NN1-3E, is a medical device, but it falls under the category of a non-invasive physiological monitoring device, not an IVD.
N/A
Intended Use / Indications for Use
The Wrist Watch Blood Pressure Monitor, Model BP3NN1-3E is a device intended to measure the systolic and diastolic blood pressure and pulse rate of an adult individual by using a non-invasive oscillometric technique in which an inflatable cuff is wrapped around the wrist for a circumference range from 13.5 to 21.5cm.
The device detects the appearance of irregular heartbeat during measurement and gives a warning signal with the reading once the irregular heartbeat is detected.

Device Description
Microlife Wrist Watch Blood Pressure Monitor, Model BP3NN1-3E 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 semiconductor 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 can detect electrical signals while inflating . And the device has Irregular Heartbeat Detection (IHD) function. It detects the appearance of irregular heartbeat during measurement and the irregular heart beat symbol "MA" is displayed on the LCD screen if any irregular heart beat signal has been detected. In addition, the device has traffic light function.

Summary of Performance Studies
The subject device Model BP3NN1-3E is from the technical point of view, identical to the predicate blood pressure monitor. Moreover, the measurement algorithm and its program codes of BP3NN1-3E remain unchanged. The fundamental scientific technology of the modified BP3NN1-3E device is the same as the predicate device BP3MO1-3P. Therefore the performance of the BP3NN1-3E in terms of blood pressure measurement would be identical with performance of the predicate device BP3MO1-3P. Repeat clinical testing in accordance with the standard ANSI/AAMI IEC81060-2 for the subject device BP3NN1-3E is therefore not necessary as clinical testing results were not affected by the changes to the subject modified device.

Our method to define systolic and diastolic pressure is similar to the auscultatory method but uses a semiconductor sensor rather than a stethoscope and mercury manometer.

during measurement and the irregular heart beat symbol "MA" is displayed on the LCD screen if any irregular heart beat signal has been detected. In addition, the device has traffic light function.
5. Intended Use:
The Wrist Watch Blood Pressure Monitor, Model BP3NN1-3E is a device intended to measure the systolic and diastolic blood pressure and pulse rate of an adult individual by using a non-invasive oscillometric technique in which an inflatable cuff is wrapped around the wrist for a circumference range from 13.5 to 21.5cm.
The device detects the appearance of irregular heartbeat during measurement and gives a warning signal with the reading once the irregular heartbeat is detected.
Comparison to the 510(k) Cleared Devices (Predicate Devices): 6.
The subject BP3NN1-3E uses the same oscillometric method as the predicate BP3MO1-3P 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.
The subject BP3NN1-3E and the predicate BP3MO1-3P both have a traffic light function, IHD function, and IMT technology. They differ by the sensor they use. The sensor of the modified device is changed to semi-conductor, while the sensor of predicate device is capacitive. However, the sensor difference has no impact on the clinical accuracy in terms of blood pressure detection according to the internal clinical test compared semiconductor and capacitive sensor.
The sensor is the same as used in the predicate device, Model BP3AX1, with 510(k) cleared number K040002.
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 BP3NN1-3E 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.
The following testing was conducted to prove safety and effectiveness as well as substantial equivalence to the predicate devices:
The following National and International Standards were utilized for testing the subject device:

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 BP3NN1-3E tested met all relevant requirements of the aforementioned tests.
8. Discussion of Clinical Tests Performed:
The subject device Model BP3NN1-3E is from the technical point of view, identical to the predicate blood pressure monitor. Moreover, the measurement algorithm and its program codes of BP3NN1-3E remain unchanged. The fundamental scientific technology of the modified BP3NN1-3E device is the same as the predicate device BP3MO1-3P. Therefore the performance of the BP3NN1-3E in terms of blood pressure measurement would be identical with performance of the predicate device BP3MO1-3P. Repeat clinical testing in accordance with the standard ANSI/AAMI IEC81060-2 for the subject device BP3NN1-3E 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:
Conclusions drawn from the non-clinical and clinical tests demonstrate that the subject device is as safe, effective, and performs as well as the predicate device.
