No
The description focuses on standard oscillometric blood pressure measurement and irregular heartbeat detection using established techniques, with no mention of AI or ML. The performance studies are based on electrical, mechanical, environmental, and standard blood pressure measurement testing, not AI/ML model validation.
No
The device is intended to measure blood pressure and pulse rate, and detect irregular heartbeats, which are diagnostic/monitoring functions, not therapeutic interventions.
Yes
Explanation: The device measures systolic and diastolic blood pressure and pulse rate, and it also detects irregular heartbeats, which are all diagnostic indicators of a patient's health status.
No
The device description clearly indicates it is a physical blood pressure monitor with an inflatable cuff and electronic pressure sensor, which are hardware components. While it includes software (Microlife Blood Pressure Analyzer BPA software), it is not solely software.
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 such as blood, urine, or tissue that have been taken from the human body to detect diseases or other conditions.
- Device Function: The Microlife Wrist Watch Blood Pressure Monitor, Model BP3BS1-3C measures blood pressure and pulse rate using a non-invasive technique (a cuff wrapped around the wrist). It analyzes pressure changes within the cuff.
- No Sample Analysis: The device does not analyze any biological samples taken from the body. It interacts directly with the body externally.
Therefore, it falls outside the definition of an In Vitro Diagnostic device.

Device Description
Microlife Wrist Watch Blood Pressure Monitor, Model BP3BS1-3C is designed to measure systolic and diastolic blood pressure, 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 an electronic 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 an Irregular Heartbeat Detection (IHD) function. It detects the appearance of irregular heartbeat during measurement and the irregular heart beat symbol "is displayed on the LCD screen if any irreqular 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.

Clinical Tests:
ANSI/AAMI SP10: 2008 "National Standard for Manual, Electronic or Automated Sphygmomanometers" testing was performed. All relevant sections were addressed and testing conducted. The BP3BS1-3C met all relevant requirements of this standard, as applicable to our modified device.
The BP3BS1-3C is, from a technical point of view, identical to the predicate device, Model BP3MK1-3 (BP W100). 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 BP3MK1-3 (BP W100) device. Therefore the performance of the BP3BS1-3C in terms of blood pressure measurement would be identical with performance of the predicate BP3MK1-3 (BP W100) device. Repeat clinical testing in accordance with the standard ANSI/AAMI SP10 for the subject BP3BS1-3C device is therefore not necessary as clinical testing results were not affected by the changes to the subject modified device.

5. Intended Use:
The Microlife Wrist Watch Blood Pressure Monitor. Model BP3BS1-3C 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.
The device detects the appearance of irregular heartbeat during measurement and gives a warning signal with the reading once the irreqular heartbeat is detected.
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.
6. Comparison to the 510(k) Cleared Device (Predicate Device):
The modified device model BP3BS1-3C and the predicate device model BP3MK1-3 (BP W100) use the well-known oscillometric method within the software algorithm to determine the systolic and diastolic blood pressure and pulse rate. Wrist cuff is inflated automatically, deflation rate is controlled by one factory set exhaust valve and the deflation pressures are transferred to one sensor.
The major difference between the two models is the additional feature PC-link function. However, the difference does not affect the accuracy and normal use of this device.
The PC-link function is similar with what is used in the predicate device BP3BU1-4U, which was 510(k) cleared under K061558.
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 BP3BS1-3C 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:
- 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 ﮩﺖ
2
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 BP3BS1-3C tested met all relevant requirements of the aforementioned tests.
8. Discussion of Clinical Tests Performed:
ANSI/AAMI SP10: 2008 "National Standard for Manual, Electronic or Automated Sphygmomanometers" testing was performed. All relevant sections were addressed and testing conducted. The BP3BS1-3C met all relevant requirements of this standard, as applicable to our modified device.
The BP3BS1-3C is, from a technical point of view, identical to the predicate device, Model BP3MK1-3 (BP W100). 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 BP3MK1-3 (BP W100) device. Therefore the performance of the BP3BS1-3C in terms of blood pressure measurement would be identical with performance of the predicate BP3MK1-3 (BP W100) device. Repeat clinical testing in accordance with the standard ANSI/AAMI SP10 for the subject BP3BS1-3C device 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". In addition, since our device requires the use of off-the-shelf software to operate the PC-link function, we adhered to the FDA September 1999 document "Guidance for Off-The-Shelf Software Use in Medical Devices".
10. Conclusions:
We have demonstrated that there are no significant differences between the Microlife Wrist Watch Blood Pressure Monitor Model BP3BS1-3C and the predicate devices, Model BP3MK1-3 (BP W100) and Model BP3BU1-4U, 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.
