Intended Use

The Microlife Wrist Watch Blood Pressure Monitor, Model BP3MO1-3P 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 BP3MO1-3P 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 can detect electrical signals while inflating. And the device has Irreqular Heartbeat Detection (IHD) function. It detects the appearance of irreqular heartbeat during measurement and the irregular heart beat symbol "44 " is displayed on the LCD screen if any irreqular heart beat signal has been detected. ' In addition, the device has traffic light function.

AI/ML Overview

The provided text does not contain detailed acceptance criteria and a study that proves the device meets specific performance criteria. Instead, it describes a 510(k) summary for a blood pressure monitor, focusing on its substantial equivalence to predicate devices and general non-clinical testing.

However, based on the information provided, here's what can be extracted and inferred:

1. A table of acceptance criteria and the reported device performance:

The document explicitly states that a repeated clinical test in accordance with the standard ANSI/AAMI SP10 was not necessary because the subject device (BP3MO1-3P) is technically identical to a predicate device (BP3MK1-3) and internal testing demonstrated that design changes did not affect clinical accuracy.

Therefore, specific numeric acceptance criteria and reported device performance from a dedicated clinical study against those criteria are not available in this document. The "Performance" is indirectly reported by the claim of substantial equivalence and no impact on accuracy from internal testing.

Acceptance Criteria (Inferred from industry standards)Reported Device Performance (as stated in the document)
Blood pressure detection accuracy (e.g., mean difference and standard deviation from reference method as per ANSI/AAMI SP10)"The internal clinical test on BP3MO1-3P demonstrates that the clinical accuracy in terms of blood pressure detection and normal use of this device is not affected by change of signal detection technology to IMT technology. The other differences (traffic light function and medication alarm function) have no impact on the clinical accuracy in terms of blood pressure detection."
Irregular Heartbeat Detection (IHD) function performanceDevice "detects the appearance of irregular heartbeat during measurement and gives a warning signal." (No specific accuracy metrics provided).
Pulse rate detection accuracyImplied to be accurate and unaffected, similar to blood pressure.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

The document mentions an "internal clinical test on BP3MO1-3P," but it does not specify the sample size for this test. It also does not specify the country of origin of the data or whether it was retrospective or prospective.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

The document provides no information on the number of experts used or their qualifications for establishing ground truth for any internal clinical testing mentioned.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

The document does not specify any adjudication method for the test set.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

The document describes a medical device (blood pressure monitor), not an AI algorithm. Therefore, no MRMC comparative effectiveness study involving human readers and AI assistance was conducted or reported.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:

The device is a standalone blood pressure monitor. The performance described is its inherent function of measuring blood pressure and detecting irregular heartbeats. However, the document does not use the term "standalone performance" in the context of an algorithm. The entire device's performance is standalone as per its function.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

For blood pressure monitors, the "ground truth" for accuracy is typically established by simultaneous measurements using a reference standard auscultatory method (e.g., using a mercury manometer and stethoscope by trained observers), often following protocols like those outlined in ANSI/AAMI SP10. While not explicitly stated, this is the standard practice for such devices.

8. The sample size for the training set:

The document does not mention a training set in the context of an AI algorithm or machine learning. The device operates based on the "oscillometric method," which is a well-known and established technique, not one that typically requires a large-scale "training set" in the modern AI sense.

9. How the ground truth for the training set was established:

As no training set is mentioned in the context of AI/ML, this information is not applicable/provided.

5. Intended Use:

The Wrist Watch Blood Pressure Monitor, Model BP3MO1-3P 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.

6. Comparison to the 510(k) Cleared Devices (Predicate Devices):

The subject BP3MO1-3P and the predicate device model BP3MK1-3 (BP W100). 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.

to

The differences between the two models are the IMT technology, traffic light function and medication alarm function. The traffic light function is added to the subject device, while the medication alarm function is removed from subject device. But the differences do not affect the accuracy and normal use of this device because they use the same fundamental scientific technology based on the internal clinical test on BP3MO1-3P.

The signal detection technology is same with what is used in the predicate device. Model HEM-609N, with 510(k) cleared number K042505.

The subject BP3MO1-3P and the predicate BP3MC1-PC both have 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 BP3MO1-3P 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.

{2}------------------------------------------------

  • a. Reliability Test Storage test
  • Reliability Test Operating test ﻗ
  • Reliability Test Vibration test ﻥ
  • d. Reliability Test Drop test
  • e. Reliability Test Life test
  • EMC Test f.

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 BP3MO1-3P tested met all relevant requirements of the aforementioned tests.

Discussion of Clinical Tests Performed: 8.

The subject device Model BP3MO1-3P is from the technical point of view, identical to the predicate blood pressure monitor Model BP3MK1-3 (BP3MK1-3). The internal clinical test on BP3MO1-3P demonstrates that the clinical accuracy in terms of blood pressure detection and normal use of this device is not affected by change of signal detection technology to IMT technology. The other differences (traffic light function and medication alarm function) have no impact on the clinical accuracy in terms of blood pressure detection. Therefore repeated clinical test in accordance with the standard ANSI/AAMI SP10 is not necessary.

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".
