摘要
用廉价的TP-801单板计算机及A/D,D/A电路构成自动处理系统。该系统对血压(或心室内压)信号进行实时处理,定时打印心率、收缩压,舒张压及平均压。也可单独作为心率计,由数码管显示心率,并于D/A转换器输出至描记仪。
ABSTRACT An auto-processing system used to record the blood pressure signal was designed. It consists of a low price TP-801 microcomputer and A/D—D/A converting circuits. The system may be used to process the blood pressure (or intra-ventricula pressure) signals and to print heart rate (HR), systolic pressure, diastolic pressure, mean arterial pressure in an assigned time interval. It can be also used as HR counter, HR can be displayed by LED display of TP-801 and inputo ink-recorder system by D/A converting circuit.
