近十多年来生物医学的一个重要特点,是电子工程技术越来越广泛地渗透、影响和促进了生物医学的发展。在日益增加的电子医疗仪器中,病人监护装置作为一个新的分支,在国内外都得到迅速的发展。国外医院中已普遍采用,并且从床边单参数监护,发展到多床位、多参数的集中监护。我国最近几年已有床边监护仪的生产,而中心监护系统也正在研制中,不少医院已投入临床使用。实践表明,使用监护仪对冠心病人和危重病人的急救以及其他一些病人的监护,具有肯定的临床效果。一、监护系统工作原理病人监护仪器是在诊断测量仪器的基础上发展起来的,把原来用于诊断测量的部分生理参数,例如:心电图、心率、体温、呼吸和血压等;进行连续的测量和显示,使医护人员及时方便地了解病情 An important feature of biomedicine in the past decade or so has been the increasingly widespread penetration of electronic engineering technology, which has influenced and promoted the development of biomedicine. In a growing number of electronic medical devices, patient monitoring devices, as a new branch, have been rapidly developed both at home and abroad. Foreign hospitals have been widely used, and from the bedside single-parameter monitoring, the development of more beds, multi-parameter centralized care. In recent years, the bedside monitor has been manufactured in our country, and the center monitoring system is under development. Many hospitals have already put into clinical use. Practice shows that the use of monitors on patients with coronary heart disease and critically ill patients and custody of some other patients, with certain clinical results. First, the monitoring system works Patient monitoring equipment is developed on the basis of diagnostic measurement instruments, the original part of the physiological parameters used for diagnostic measurements, such as: ECG, heart rate, body temperature, respiration and blood pressure; continuous measurement and Display, so that medical staff in a timely manner to understand the condition
