Device Description Blood Pressure Monitor TMB-2287-B is designed to measure systolic pressure, diastolic pressure and pulse rate of adult by a non-invasive technique, with an inflatable cuff wrapped around the upper arm. The method to define systolic and diastolic pressure is similar to auscultatory method, though it uses an electronic pressure sensor rather than a stethoscope and mercury manometer. The sensor converts tiny alternations of cuff pressure into electrical signals. Based on analysis of these signals, the systolic and diastolic blood pressure is defined, and the pulse rate is calculated. This is an extensively used technique applied in blood pressure monitors, also known as "oscillometric method". The main components of the Blood Pressure Monitor include main unit and cuff. For the outer housing of the main unit, it's made of HIPS material. As for accompanying cuffs, five types of cuffs have been clinically validated to be matched with the device, suitable for population aged at or over three and with arm circumference from 22cm~52cm. The cuff is consisted of fabric and an inflatable bladder inside. For critical electronic components, there is medical switch power supply, PCB, thermistor, pressure pump, motor, release valve and pressure sensor. The device also enjoys a function of detecting irregular pulse rate. When measurements were {5}------------------------------------------------ performed, the monitor will record all pulse intervals and calculate the average. If two or more pulse intervals were recorded, and the difference between each interval and the average is larger than ±25% of the average; or if four or more pulse intervals were recorded, and the difference between each interval and the average is larger than ± 15% of the average, the irregular pulse symbol will be displayed along with measurement results. An embedded Bluetooth wireless connection module in the device allows it to connect with matching receiving ends. When a measurement is done, the results will be displayed on LCD, and the measured data will be transferred to the APP via Bluetooth. With the use of software (including APP) and Bluetooth communication module, the wireless software function and hardware function are solely intended to transfer, store, convert formats, or display medical device data and results (blood pressure and pulse rate readings), without controlling or altering the functions or parameters of any connected medical devices, which is not be intended for active patient monitoring, therefore, based on the FDA guidance titled "Medical Device Data Systems, Medical Image Storage Devices, and Medical Image Communications Devices" (issued on September 28, 2022.), this software function is belong to Non-device-MDDS, and the hardware function is belong to Device-MDDS, they are not subject to FDA laws and regulations applicable to devices. ### 5.
