A&D UB-322 WATCH STYLE WRIST DIGITAL BLOOD PRESSURE MONITOR by A & D ENGINEERING, INC.

The UB-322 is designed to be used by end users who are eighteen (18) years and older at home to monitor their blood pressure (systolic and diastolic) and pulse rate. The end user should not have common arrhythmias, such as atrial or ventricular premature beats or atrial fibrillation. UB-322 is using oscillometric method to conduct the measurement. It is not designed for ambulatory use. The wrist circumference range shall be within 5.3 inches to 7.7 inches.

Device Description

UB-322 Watch Style Wrist Digital Blood Pressure Monitor

AI/ML Overview

This document is a 510(k) clearance letter from the FDA for a blood pressure monitor, not a study report detailing acceptance criteria and performance data. Therefore, the requested information cannot be fully extracted from the provided text.

Specifically, the document does not contain:

A table of acceptance criteria and reported device performance.
Details about the study design, sample sizes (for test or training sets), data provenance, number or qualifications of experts, or adjudication methods.
Information about MRMC studies, standalone algorithm performance, or how ground truth was established.

The document primarily states that the A&D UB-322 Watch Style Wrist Digital Blood Pressure Monitor has been found "substantially equivalent" to predicate devices marketed prior to May 28, 1976. It specifies the "Indications for Use" as:

For end-users 18 years and older at home.
To monitor blood pressure (systolic and diastolic) and pulse rate.
Not for users with common arrhythmias (atrial or ventricular premature beats or atrial fibrillation).
Uses the oscillometric method.
Not designed for ambulatory use.
Wrist circumference range: 5.3 inches to 7.7 inches.

The FDA clearance process for a 510(k) relies on demonstrating substantial equivalence, which often involves comparing the new device's performance to an existing legally marketed predicate device. The detailed performance criteria and the study results demonstrating how the device met those criteria would typically be found in the 510(k) submission itself or a separate validation report, not in the FDA's clearance letter.

Dear Mr. Mosenkis:

We have reviewed your Section 510 (k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
