Wrist style electronic blood pressure monitor The oscillometric method is the use of blood by the sphygmomanometer ligature balloon tamponade hindered stops flowing gradually relieve the pressure within the airbag so that the blood starts flowing intermittently with the heart beating, and to measure blood pressure pulse of the pulsatile with a patmethod; gradually relieve straps balloon tamponade and process pulsation of blood vessels than the previous beat increases rapidly straps airbags blood pressure is the most hypertension (systolic blood pressure); contrary, steadily began arterylast, the pressure the ligature airbag is the minimum blood pressure (diastolic pressure). What is the diastolic blood pressure; systolic blood pressure and pulse? 1.Systolic blood pressure (hypertension), when a heart contraction, the intake of blood from the ventricle side pressure on the vessel wall, when the blood pressure maximum. 2.Diastolic blood pressure (low pressure) end-diastolic heart, blood temporarily stop the intake of artery stretch and tension on the vascular wall. Inflow of arterial blood continues to flow, there is still pressure on the vessel wall, when blood pressure is called the diastolic blood pressure. 3.Pulse is the heart beating 4.Normal blood pressure values Specifications: Item BLS****3 Theory Oscillography Measurement site Wrist Material ABS&PP Size *6**8mm Screen display year,month,day;Systolic;Diastolic;Pulse and memory function Lifetime ****0 times Voltage DC3V Storage space 2**0groups Close style Manually (auto shut off after idleness one mins) Inflation style Auto inflation Deflation style Auto deflation Measurement range Blood pressure (****9mmHg) (***9.9kPa) Pulse (*****9times/mins) Measurement precision Blood pressure (±3mmHg) (±0.4kPa) Pulse (measured value5%) Use environment Temperature (5 degree to *0 degree) Humidity (*5%**5% RH) Carton size *3**6**3cm Quantity *0pcs/ctn Gross weight *2kg/ctn Certificates CE,ROHS Configuration 1.Blood pressure monitor 2.manual
