Intended Use

The UA-767F and UA-767FAC are designed to be used by users who are older than twelve (12) years at home or clinics to monitor their blood pressure (systolic and diastolic) and pulse rate. The arm circumference range shall be between 8.7 inches (22.0 cm) and 17.7 inches (45.0 cm).

Device Description

UA-767F and UA-767FAC have the same design except UA-767FAC having an AC plug for an external AC adapter connection. Both devices use an inflatable cuff which is wrapped around the patient's upper arm. After the user pushes the "START" button, the cuff is inflated automatically by an internal pump of UA-767F and UA-767FAC. The systolic and diastolic blood pressures are determined by oscillometric method. The deflation rate is controlled by the internal exhaust valve. There is a quick exhaust mechanism so that the cuff pressure can be completely released urgently. There is a maximum pressure safety setting at 300mmHg. UA-767F and UA-767FAC will not inflate the cuff higher than 300mmHg. UA-767F and UA-767FAC will turn on an irregular heartbeat indicator if an irregular heartbeat was detected during the measurement process. At the end of the measurement, the systolic and diastolic pressures with pulse rate are shown on the LCD and stored in the device memory. The cuff is also deflated automatically to 0 mmHg at the same time.

AI/ML Overview

This document is a 510(k) K141201 premarket notification from A&D Engineering, Inc. for their UA-767F and UA-767FAC Digital Blood Pressure Monitors. This type of submission focuses on demonstrating substantial equivalence to a predicate device, rather than conducting a de novo clinical trial with specific acceptance criteria and detailed study results as would be found in a PMA.

Therefore, the requested information, particularly regarding a multi-reader multi-case (MRMC) comparative effectiveness study, standalone algorithm performance, and detailed ground truth establishment for training and test sets, is not applicable to this type of regulatory submission and is not provided in the document. This submission primarily relies on compliance with recognized standards and a comparison of technical specifications to predicate devices.

1. Table of acceptance criteria and the reported device performance

The document doesn't explicitly define "acceptance criteria" in the context of a clinical trial for individual performance metrics, but rather references adherence to recognized standards like ANSI/AAMI/IEC 80601-2-30:2009 for "essential performance." The key performance metrics mentioned are accuracy for blood pressure and pulse rate, which align with the requirements of such standards.

Performance MetricAcceptance Criteria (from standard references)Reported Device Performance (UA-767F & UA-767FAC)
Blood Pressure Accuracy+/- 3mmHg (or +/- 2% of measured value for predicate)+/- 3mmHg
Pulse Accuracy+/- 5 % (pulse)+/- 5 %
Measurement Range (BP)20 to 280 mmHg (predicate)0 - 299 mmHg
Measurement Range (Pulse)30 to 200 beats/min30 to 200 beats/min
Maximum Pressure SafetyN/A (implied by standard adherence)No inflation higher than 300mmHg
Irregular Heartbeat DetectionMore than +/-25% to the mean interval of all pulse intervals (predicate)No change – the same

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 does not provide details of a specific clinical test set with sample size, data provenance, or study design (retrospective/prospective). The submission relies on "design verification and design validation activities based on the comparison... with the predicate devices" and adherence to recognized international standards. This suggests testing was likely internal and focused on meeting technical specifications rather than a full-scale clinical trial.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This information is not applicable and not provided in the document. The device is a non-invasive blood pressure monitor that directly measures physiological parameters, not an AI or imaging device requiring expert interpretation for ground truth.

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

This information is not applicable and not provided in the document, as it pertains to expert adjudication of ground truth for interpretive devices, which this is not.

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

No. This is not an AI-assisted device and therefore an MRMC study is not relevant or included in this submission.

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

The device itself is a standalone blood pressure monitor. Its performance is measured directly against reference standards (as implied by adherence to standards like ANSI/AAMI/IEC 80601-2-30), not as an algorithm's output requiring human interpretation as a separate step. The document states, "The systolic and diastolic blood pressures are determined by oscillometric method." The reported accuracy falls under the device's inherent design and measurement capabilities.

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

For blood pressure monitors, "ground truth" typically refers to measurements obtained through a validated reference method (e.g., auscultation by trained observers using a mercury sphygmomanometer) as part of the testing required by standards like ANSI/AAMI/IEC 80601-2-30. The document does not explicitly state the specific method used for ground truth, but its reliance on these standards implies their methodologies were followed.

8. The sample size for the training set

This information is not applicable and not provided. This device is a hardware-based measurement device, not an AI/machine learning model that typically relies on a "training set."

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

This information is not applicable and not provided, as there is no "training set" in the context of this device.

4. Predicate Devices

A&D Model UA-767PBT Digital Blood Pressure Monitor with 510(k) number K043217 A&D Model UA-1000 Family Digital Blood Pressure Monitors with 510(k) number K111686 Predicate devices are designed and manufactured by the same company and facilities as the modified devices UA-767F and UA-767FAC.

ട. Device Description - Technological and Operational Characteristics

UA-767F and UA-767FAC have the same design except UA-767FAC having an AC plug for an external AC adapter connection. Both devices use an inflatable cuff which is wrapped around the patient's upper arm. After the user pushes the "START" button, the cuff is inflated automatically by an internal pump of UA-767F and UA-767FAC. The systolic and diastolic blood pressures are determined by oscillometric method. The deflation rate is controlled by the internal exhaust valve. There is a quick exhaust mechanism so that the cuff pressure can be completely released urgently. There is a maximum pressure safety setting at 300mmHg. UA-767F and UA-767FAC will not inflate the cuff higher than 300mmHg. UA-767F and UA-767FAC will turn on an irregular heartbeat indicator if an irregular heartbeat was detected during the measurement process. At the end of the measurement, the systolic and diastolic pressures with pulse rate are shown on the LCD and stored in the device memory. The cuff is also deflated automatically to 0 mmHg at the same time.

Discussion of standards used in the design verification and design validation 8.

We conducted design verification and design validation activities based on the comparison of the UA-767F and UA-767FAC with the predicate devices. Based on the changes, we conducted the appropriated test methodology and pass/fail criteria. After the tests were conducted, the test records were collected in the design history file (DHF).

A&D Medical follows FDA regulation and international standards in our medical device development and manufacturing processes. The following standards were used to demonstrate compliance to FDA recognized consensus standards for the UA-767F and UA-767FAC devices.

  • . ANSI/AAMI/IEC 80601-2-30:2009 Medical electrical equipment - Part 2-30: Particular requirements for the basic safety and essential performance of automated noninvasive sphygmomanometers.
  • . AAMI/ANSI 60601-1:2006 Medical electrical equipment. General requirements for basic safety and essential performance
  • AAMI/ANSI/IEC 60601-1-2:2007 Medical electrical equipment. General ● requirements for basic safety and essential performance. Collateral standard. Electromagnetic compatibility. Requirements and tests
  • . AAMI/ANSI/ISO 14971:2012 Medical devices. Application of risk management to medical devices

There is no new material involved from the predicate devices to UA-767F and UA-767FAC. So, there is no need to conduct any biocompatibility tests.

UA-767F and UA-767FAC met all applicable requirements of the standards. None of the test demonstrated that the UA-767F and UA-767FAC bring new issues of safety and effectiveness.

Substantial Equivalence Conclusion:

UA-767F and UA-767FAC Digital blood pressure monitors have the following similarities to the predicate devices, UA-1000 family and UA-767PBT digital blood pressure monitors, which previously received the 510(k) clearance.

As a conclusion, the intended use of the modified device, UA-767F and UA-767FAC as described in its labeling, has not changed as a result of the modifications. The fundamental scientific technology of the modified device, UA-767F and UA-767FAC, has not changed, either. The results of the previous activities demonstrate that the A&D Medical UA-767F and UA-767FAC Digital Blood Pressure Monitors are as safe, as effective, and performs as well as or better than the predicate devices.
