A new device for an automatic determination of coronary sinus blood flow using the thermodilution technique is presented. The measuring equipment consists of four main parts; a thermal dilution-catheter with two signal amplifiers of analogue type, an analogue/digital converter controlled by a microcomputer system, a pump for the control of the rate of injection flow and a control panel and display. The device has been tested in a model test with flow levels between 75 and 200 ml/min. The error between a number of measurements with all parameters unchanged except minor variations in temperatures was less than 5 per cent.
介绍了一种采用热稀释技术自动测定冠状窦血流量的新装置。测量设备由四个主要部分组成：一个带有两个模拟型信号放大器的热稀释导管、一个由微型计算机系统控制的模拟/数字转换器、一个用于控制注射流速的泵以及一个控制面板和显示器。该装置已在流量水平为75至200毫升/分钟的模型试验中进行了测试。在除温度有微小变化外所有参数均保持不变的多次测量中，误差小于5%。
