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.

#### Device Description: 4.
Microlife Upper Arm Automatic Digital Blood Pressure Monitor, Model BP3MW1-4X(R) is designed to measure systolic and diastolic blood pressure, pulse rate of an individual by using a non-invasive technique in which one inflatable cuff is wrapped around the single upper arm. Our method to define systolic and diastolic pressure is similar to the auscultatory method but use two resistive pressure sensors rather than a stethoscope and mercury manometer. The sensors convert 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 accurately measure blood pressure in pregnant patients including those with known or suspected preeclampsia.
The device detects the appearance of irregular heartbeat during measurement, and the symbol " " "is displayed after the measurement. In addition, the device can be used in connection with your personal computer (PC) running the software. The memory data can be transferred to the PC by connecting the monitor with the PC via cable.

The device can be used in connection with your personal computer (PC) running the Microlife Blood Pressure Analyzer (BPA) software. The memory data can be transferred to the PC by connecting the monitor via cable with the PC.
#### 6. Comparison to the 510(k) Cleared Device (Predicate Device):
The modified subject device model BP3MW1-4X(R) and the predicate device model BP3MC1-PC use the well-known oscillometric method within the software algorithm to determine the systolic and diastolic blood pressure and pulse rate. Upper arm cuff is inflated automatically, deflation rate is controlled by one factory set exhaust valve and the deflation pressures are transferred via tubing to one (or two) sensor(s).
They differ by the early preeclampsia function. AM/PM average function and the operating button. The button of the predicate device is a traditional button, and the buttons of the subject device are touch pad "buttons" which operate similarly to traditional buttons, but require only a light touch of the finger to operate.
Although the cuff used with the subject BP3MW1-4X(R) is changed to a WRR conical cuff, it is the same cuff as cleared in BP3AP1-3E. K111652. The subject device now includes an early pre-eclampsia function. validated according to the ANSI/AAMI/ISO 81060-2:2009 protocol. The
