Intended Use

The Panasonic wrist blood pressure meter, model EW 284, is intended to measure systolic and diastolic blood pressure using a pressurized cuff worn around the wrist.

Device Story

Battery-powered digital electronic blood pressure meter; uses pressurized cuff worn on wrist to measure systolic/diastolic blood pressure and pulse rate. Device features memory storage for 60 readings, recall/memory/clear buttons, and audible tone control. Operated by user; intended for non-invasive monitoring. Output displayed on screen; provides blood pressure values and pulse rate. Benefits include convenient, portable blood pressure tracking for users.

Clinical Evidence

Bench testing only. Hardware and software testing conducted to verify that modifications to model EW284 did not affect safety or effectiveness. All devices passed testing.

Technological Characteristics

Battery-charged non-invasive digital electronic blood pressure meter. Features pressurized cuff, LCD display, 60-reading memory, and audible tone switch. Modifications include harmonized JIS specifications, expanded measurement range (0-300 mmHg), and updated operational buttons. Noise safety <65 dB at 1m.

Indications for Use

Indicated for the measurement of systolic and diastolic blood pressure in individuals using a wrist-worn pressurized cuff.

Regulatory Classification

Identification

A noninvasive blood pressure measurement system is a device that provides a signal from which systolic, diastolic, mean, or any combination of the three pressures can be derived through the use of tranducers placed on the surface of the body.

## PREDICATE DEVICE

#### Name of Predicate Devices A.

Panasonic wrist blood pressure meter, models EW273, EW277, EW278, and EW279.

#### B. Device Description

The wrist blood pressure meter is a battery-charged non-invasive digital electronic blood pressure meter manufactured by Matsushita Electric Works, Ltd., (MEW) Osaka, Japan. The wrist blood pressure meter is intended to measure systolic and diastolic blood pressure using a pressurized cuff worn around the wrist.

#### IV. BACKGROUND

In 1995, the Panasonic wrist blood pressure meter models EW273, EW278, and EW279 were cleared for market (K942422). Panasonic intends to market an additional device, model EW284. This model is substantially equivalent to Panasonic's previously cleared devices.

#### DEVICE DESCRIPTION V.

Model EW284 is a wrist blood pressure meter.

#### VI. INTENDED USE

Model EW284 is intended to measure systolic and diastolic blood pressure using a pressurized cuff worn around the wrist.

#### SUBSTANTIAL EQUIVALENCE COMPARISON VII.

## Intended Use

The intended use for model EW284 is identical to that of Panasonic's 510(k) cleared wrist blood pressure meter models.

## Technological Characteristics

The design of model EW284 is the same as Panasonic's previously cleared wrist blood pressure meter models EW273, EW277, EW278, and EW279. Minor modifications were made to product specifications to harmonize with Japan Industry Standards (JIS). The measurement range, display functionality, and device dimensions were also modified for ease of use. Data memory and retention have increased from 30 to 60 readings. Three buttons and a switch were added. The recall, memory, and memory clear buttons can be

used to obtain or delete pulse rate information that is stored in memory. The "♪" switch allows the user to control whether audible tones are provided during measurement, when an error occurs, and at the conclusion of the measurement. Differences between model EW284 and Panasonic's previously cleared devices are described in Table 1.

# VIII. PERFORMANCE DATA

Hardware and software testing was conducted to verify that the changes made to model EW284 have not affected the safety and effectiveness of this device. All devices passed all tests and are qualified for use.

#### CONCLUSIONS IX.

The Panasonic Corporation wrist blood pressure meter, model EW284, is substantially equivalent to previously cleared Panasonic Wrist Blood Pressure Meter models EW273, EW277, EW278, and EW279.
