#### Device Description 3.

Digital Automatic Blood Pressure Monitor MD3600 (Subject Device) are non-invasive blood pressure measurement systems for use by medical professional or at home. It is designed to measure the systolic and diastolic blood pressure, and pulse rate of an individual in each measurement and then display the readings on a digital panel.

The Subject Device utilize the oscillometric methodology, in which an inflatable cuff is wrapped around the upper arm of an individual, for blood pressure measurement. This means the monitor detects your blood's movement through your brachial artery and converts the movement into a digital reading.

The Subject Device equipped with Bluetooth transmission, which enable user to transfer the measurement record from the device to a mobile platform through Bluetooth. User can manage the measurement record by using the mobile application.
