Description
Technical field
The present invention relates to technical field of medical instruments, be specifically related to a kind of Portable Electronic Blood Pressure Monitor system.
Background technology
The causing circulatory of human body comprises heart, blood vessel and lymphsystem, is interconnected between them, forms " tubing " substantially closed.Normal heart is a strong muscular organ, and just as a water pump, it is beaten around the clock, with having the rhythm and pace of moving things.The contracting of one one, heart, makes blood seething in causing circulatory.Blood is when intravascular flow, and no matter heart contraction or diastole, all produces certain pressure to blood vessel wall.Pressure when the heart contracts in large artery trunks is the highest, and blood is at this moment called " high pressure "; During LV Diastolic, the pressure in large artery trunks is minimum, therefore is called " low pressure ".We said " blood pressure " in fact refers to upper arm brachial artery at ordinary times, i.e. the blood pressure determination of arm nest blood vessel is the indirect determination of aortic pressure.Usually different with the blood pressure in left side on the right side of our measuring blood pressure, the highlyest differ 10 millimetress of mercury, minimum difference is less than 5 millimetress of mercury.
Blood pressure is one of physical signs of wanting of body weight for humans, and suitable blood pressure maintains the metabolic essential condition of human normal.Because modern suffers from cardiovascular disease in the trend of becoming younger, thus in time Measure blood pressure, monitor the change of daily blood pressure to preventing and curing diseases, finding disease early, all significant.
Normal blood pressure is the prerequisite of blood circulation flowing, and blood pressure keeps normal under many factors regulates, thus provides each histoorgan with enough blood volumes, uses and maintains normal metabolism.Hypopiesia too high (hypotension, hypertension) all can cause serious consequence, and it is dead omen that blood pressure disappears, and this all illustrates that blood pressure has extremely important biological significance.
Traditional aeromometer just can carry out correct measurement blood pressure owing to needing more professional skill, which has limited the daily monitoring of ordinary people at home to blood pressure.
