Device description Wrist Blood Pressure Monitor, model: BPM-W1VL is a Noninvasive Blood Pressure Measurement System that is intended to measuring blood pressure through oscillation mensuration. The subject device will automatically start to take measurements after the inflation of the cuff is finished, the results will show the systolic pressure and diastolic pressure with pulse rate. The blood pressure monitor will store the measurements automatically; The record maybe revisited. It measures blood pressure and pulse rate through inflating cuff which rounding the wrist of patients. The BPM-W1VL is small, portable and used at home or in medical facilities environment. The Wrist Blood Pressure Monitor consists of two parts: main unit and cuffs. The BPM-W1VL is composed of PCBA, crystal oscillator, pump, valve, enclose, and LCD. ## Principle of operation: This product uses the Oscillometric Measuring method to detect blood pressure. When the cuff is fully inflated to reach a pressure above systolic pressure, no blood flow occurs through the artery. As the cuff is deflated below the systolic pressure, the reducing pressure exerted on the artery allows blood to flow through it and sets up a detectable vibration in the arterial wall. When the cuff pressure falls below the patient's diastolic pressure, blood flows smoothly through the artery in the usual pulses, without any vibration being set up in the wall. Vibrations occur at any point where the cuff pressure is sufficiently high that the blood has to push the arterial wall open in order to flow through the artery. The vibrations are transferred from the arterial wall, through the air inside the K253133 Page 2 of 9 {6} cuff, into a transducer in the monitor that converts the measurements into electrical signals. Hence when it starts inflating the cuff, meanwhile, the unit detects pressure oscillations generated by beat-to-beat pulsatile, which is used to determine the systolic and diastolic pressure, and pulse rate. And Wrist circumference is 13.5-21.5 cm. # 7. Indications for Use The Wrist Blood Pressure Monitor is intended to measure the systolic and diastolic blood pressure as well as the pulse rate of person older than twelve (12) years via non-invasive oscillometric technique in medical facilities or at home. The intended wrist circumference is 13.5-21.5 cm. # 8. Contraindication 1). Patients with severe heart (including significantly irregular heart rhythm, Bigeminy, trigeminy, isolated ventricular premature beat (VPB), atrial fibrillation), liver or kidney disease or blood circulation disorders. 2). Newborns, infants, children, people with mental disorders and people who cannot explain their thoughts; 3). The one who with upper limb trauma don't use this device; 4). The one who with artificial heart and skin ulcers is prohibited to use this device. 5). Patients are Pregnant; 6). Patients has been diagnosed with preeclampsia. 7). Patients with diabetes. 8). Patients who are undergoing vasoactive treatment. 9). Patients with (such as atrial fibrillation). 10). Patients with peripheral artery disease or other conditions that affect arterial compliance. # 9.

Moreover, bench testing contained in this submission supplied demonstrate that the differences existed between BPM-W1VL and HWA10 do not raise any new questions of safety or effectiveness. The non-clinical tests support the safety of the device and the hardware and software verification and validation demonstrate that the Wrist Blood Pressure Monitor, model: BPM-W1VL performs as intended in the specified use conditions are same with predicate device. The clinical performance tests demonstrate that the Wrist Blood Pressure Monitor, model: BPM-W1VL performs comparably to the predicate device that is currently marketed for the same intended use. Thus, the Wrist Blood Pressure Monitor, model: BPM-W1VL is Substantially Equivalent (SE) to the predicate device. 9 / 9 K253133 Page 9 of 9
