The Relaxometer is a computer-controlled system developed for reliable clinical experimental measurements on neuromuscular block. This system is based on an adapted personal computer (Atari 1040 ST) with a monochrome monitor (Atari SM 124), and a microcomputer-driven slave unit (stimulator). There are several stimulation patterns available: single twitch at 0.1 and 1 Hz, single train-of-four, continuous train-of-four every 12 seconds, and tetanic stimulation at 50 Hz for 5 seconds followed by posttetanic count. The system is equipped with a temperature module for continuous monitoring of the skin/muscle temperature and a rechargeable battery to allow uninterrupted measurements if the apparatus is disconnected from the line power. All acquired data, computer-calculated parameters (onset time, duration time, recovery index, train-of-four ratio, tetanic fade, and posttetanic count), and the mechanomyogram are presented on screen continuously, are stored on floppy disk, and can be printed in a well-organized format.
松弛度测量仪是一种为神经肌肉阻滞的可靠临床实验测量而开发的计算机控制系统。该系统基于一台适配的个人计算机（雅达利1040 ST），配有单色显示器（雅达利SM 124），以及一个由微型计算机驱动的从属单元（刺激器）。有几种刺激模式可供选择：0.1赫兹和1赫兹的单次抽搐、单次四个成串刺激、每12秒一次的连续四个成串刺激，以及50赫兹持续5秒的强直刺激，随后进行强直刺激后计数。该系统配备有一个温度模块，用于持续监测皮肤/肌肉温度，还有一个可充电电池，以便在仪器与市电断开连接时能进行不间断测量。所有采集到的数据、计算机计算的参数（起效时间、持续时间、恢复指数、四个成串刺激比值、强直衰减和强直刺激后计数）以及肌机械图会持续显示在屏幕上，存储在软盘上，并能以条理清晰的格式打印出来。
