一、前言射流技术是六十年代发展起来的一门自动控制新技术,它利用流体在特定元件中流动的某些物理现象实现自动控制。应用射流元件,可以制成各种数字式和模拟式射流自动控制装置。射流控制装置具有稳定可靠、适应性强、易于制造和结构简单等特点,在宇宙航空、原子能化工、机床、造船、医疗、轻工等部门有着广泛的应用。医学临床上使用的医疗器械,往往要求可靠性高、寿命长,结构简单,操作方便。这些正好是射流元件具有的特点。因此,射流技术一问世就受到医疗器械研制部门的重视。本文主要介绍几种射流控制的人工心脏和呼吸器。利用射流元件的振荡现象和放大作用,可以制成可靠性高、寿命长的人工心 I. Introduction Jet technology is a new automatic control technology developed in the 1960s that uses automatic control of certain physical phenomena that a fluid flows in a particular component. Application of jet components, can be made into a variety of digital and analog automatic jet control device. Jet control device is stable and reliable, adaptable, easy to manufacture and simple structure and other characteristics in the aerospace, atomic energy chemical industry, machine tools, shipbuilding, medical, light industry and other departments have a wide range of applications. Medical clinical medical equipment, often require high reliability, long life, simple structure, easy to operate. These are exactly the characteristics jet components have. Therefore, the advent of jet technology by the medical device development department attention. This article describes several jet-controlled artificial hearts and respirators. The use of jet components of the phenomenon of oscillation and amplification, can be made of high reliability, long life of the artificial heart
