在生物医学工作中常涉及计数和测量问题,象每分钟的呼吸、脉搏的次数等,还有一些医疗科研仪器,象呼吸机、灌注机等也需要计量次数,频率等参数。作者曾为医学研究参加过一种多用测量仪的研制,采用CMOS数字集成电路制成,该仪器使用CL102集成组件,使安装和调试简单,体积缩小,工作稳定,其功能得到 In the biomedical work often involves counting and measurement problems, such as the number of breaths per minute, pulse, etc., and some medical research equipment, such as ventilators, perfusion machines, also need to measure frequency, frequency and other parameters. The author has participated in the development of a multi-purpose measuring instrument for medical research, using CMOS digital integrated circuits, the instrument uses CL102 integrated components, so that the installation and commissioning is simple, the volume is reduced, the work is stable, and its function
