More Information

Not Found

No
The summary describes a standard digital blood pressure meter and does not mention any AI or ML capabilities.

No
Explanation: The device is intended to measure blood pressure, not to treat any condition. While it can be used in a therapeutic context (e.g., monitoring blood pressure during treatment), its primary function as described is measurement, not therapy.

No

Explanation: The device measures blood pressure, which is a physiological parameter, but the provided text does not state that it is used to diagnose a medical condition. It is a measurement device, not a diagnostic one.

No

The device description explicitly states it is a "digital electronic blood pressure meter" and mentions a "pressurized cuff worn around the wrist," indicating it includes hardware components for measurement.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD devices are used to examine specimens derived from the human body (like blood, urine, or tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening.
  • This device measures blood pressure in vivo (within the body) by applying a cuff to the wrist. It does not analyze any bodily fluids or tissues.

The description clearly states its purpose is to measure blood pressure using a cuff worn around the wrist, which is a non-invasive, in vivo measurement.

III. PREDICATE DEVICE

A. Name of Predicate Devices

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, EW277, EW278, and EW279 were cleared for market (K942422). Panasonic intends to market an additional device, model EW280. This model is substantially equivalent to Panasonic's previously cleared devices.

V. DEVICE DESCRIPTION

Model EW280 is a wrist blood pressure meter.

VI. INTENDED USE

Model EW280 is intended to measure systolic and diastolic blood pressure using a pressurized cuff worn around the wrist.

VII. SUBSTANTIAL EQUIVALENCE COMPARISON

Intended Use

The intended use for model EW280 is identical to that of Panasonic's 510(k) cleared wrist blood pressure meter models.

Technological Characteristics

The design of model EW280 is the same as previously cleared Panasonic 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. Differences between model EW280 and Panasonic's previously cleared devices are described in Table 1.
