【Abstract】 The independently clinical electrolyte analyzers designed by domestic enterprises tend to plug easily and process data poorly.Therefore the design in which the distribution valve is replaced by the electromagnetic valve is proposed to keep the pipeline unobstructed;furthermore,the AC980 clinical electrolyte analyzer is designed on the basis of the ARM7 processor.Based on this,a programming method which is multi-state,multi-task and multithreading is put forward to control the whole system.A series of tests and experiments prove that the instrument has high veracity and humanized operation,completely meeting the clinical testing requirements.更多还原
