Abstract:
The paper d iscusses the osc illom etr ic me thod to m easure blood pressure, introduces both hardwa re and software system s o f theNoninvasion Dynam ic B lood PressureMon itorw ith C8051 single ch ip m icrocomputer and co lor Liqu id Crystal D isplay ( LCD ) as its core, and g iv es the flow charts. The program s are w ritten in the assemb le languag e of ASM 51. On the bas is of o sc illom etric m ethod, a fuzzy contro l me thod is introduced to rev ise autom atica lly the character istic coe ffic ient for different situa tions, and im proves the m easurem en t prec ision. The m on itor can d isp lay the blood pressure and its trend chart, a lso store and p layback b lood pressure data in 48 hours, and is convenient and effic ient in use. It can correct the errors by itse lf and is o f high clinic va lue
