摘　　要：本文介绍以ＭＣＳ—５１系列单片机为基础的医用阻抗、导纳图呼吸波消除仪的研制。它采用双ＣＰＵ并行处理结构，对反映血液循环状态的阻抗或导纳波进行动态处理，以消除呼吸波等生理干扰信号。该仪器具有模入、模出接口，可与各种医用阻抗仪及心脏功能检测仪配接。In this paper, we introduce a development of clinical admittance or impedence plethysmography breathe wave eliminating instrument which based on MCS─51 processor.Using dual processor paralell processing architecture, it dynamically processes admittance or impedence wave which reflect the status of blood circulation , and eliminates the breathe wave and other physiology interfering signals. This instrument has interfaces for input and output, so it can be connected with various kinds of clinical impedence instruments and cardiac function detecting instruments.
