Device Description

Microlife Upper Arm Automatic Digital Blood Pressure Monitor, Model BP3GT1-6X is designed to measure systolic and diastolic blood pressure and pulse rate of an individual by using a non-invasive MAM (Microlife Average Mode) technique in which an inflatable cuff is wrapped around the upper arm. Our method to define systolic and diastolic pressure is similar to the auscultatory method but uses a capacitor pressure sensor rather than a stethoscope and mercury manometer. The sensor converts 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".
And the device has Irregular Heartbeat Detection (IHD) function. It detects the appearance of irregular heartbeat during measurement and the irregular heart beat symbol "is displayed on the LCD screen if any irregular heart beat signal has been detected. In addition, the device has a traffic light function. And 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.
· The device features an interactive touch screen which operates similarly to traditional buttons, but requires only a light touch of the finger to operate.

The device detects the appearance of irregular heartbeat during measurement and gives a warning signal with the reading once the irregular heartbeat is detected.

Comparison to the 510(k) Cleared Devices (Predicate Devices):

The subject BP3GT1-6X and the predicate device model BP3AP1-3E, use the same oscillometric method with the same fundamental scientific technology to determine the systolic and diastolic blood pressure and pulse rate. Upper arm cuff is inflated automatically by pump and the pressures are transferred via tubing to a sensor in these two units.

They differ by the talking function, MAM, back light, PC-link function and the way to operate the device. The talking function is removed from the subject device; while the MAM, backlight, PC-link function is added to the subject device. The way to operate the predicate device is to press the button, and the subject device requires a light touch of the finger on the screen. But those differences do not affect the accuracy and normal use of this device because they use the same fundamental scientific technology based on clinical declaration of identity and the Declaration of Clinical Identity.

The subject BP3GT1-6X uses the same oscillometric method as the predicate BP3MC1-PC to determine the systolic and diastolic blood pressure and pulse rate. The have the same MAM, backlight, traffic light, PC-link, IHD function and intended use. Based upon the aforementioned information, the two devices are substantially equivalent.

Discussion of Non-Clinical Tests Performed for Determination of Substantial Equivalence are as follows:
