- Advanced Using innovative patent dual-balloons/airtubes/sensors technology (instead of other single balloon/sensor ordinary digital blood pressure devices) and contin uous measurement of multi-point pressure between pulses to achieve the most accurate measurement during the record of accurate real state of blood flow. Over 40 countries invention patent applied. - Reliable +/- 2mmHg high accuracy. It imitates Mercury Blood Pressure Monitor,the upper airbag functions as pump bulb for adding pressure,the lower airbag functions as Stethoscope to detect real state of blood flow via pulse wave. - Human voice reminder during the whole measurement process to help users follow the correct instructions and get the acc urate results. - Memory storage up to 100 sets of result,'MEM' button helps users search for measurement results. - Antibacterial design. Removable cuff cloth design realized anti-bacterial/ comfortable/ healthy measurement upon clean ing/replacing. - Support various arm circumference between 17-42cm. - Support data communication with PC/ HI S (Hospital Information System) via USB/ RS-232/RJ-45 ports. - Intelligent Awakening. If no on e use the BPM,it will be in dormant state; If someon e is close to or in front of the sleeve, the 8PM will wake up automatically..
