Modular design of microcomputer-based medical instruments.
A modular design approach is effective for developing compact microcomputer-based medical instruments. Each instrument consists of two modules: a microcomputer instrument module that provides data conversion and computing functions and a characteristic module that does analog signal conditioning and includes all interfaces to the environment. The five instruments summarized here are: (a) a portable, battery-operated arrhythmia monitor for ambulatory patients; (b) a physician's computer for remote telephone communication with the portable monitor; (c) a battery-powered arrhythmia monitor/recorder for the operating room; (d) a portable, battery-operated biofeedback device for speech therapy; and (e) a neuromuscular blockade monitor for the operating room.
