摘 要随着我国医疗事业的进展和计算机的普与与提高，计算机控制技术越来越多地应用于各行各业中，传统的医疗器械已经不能满足患者的需求了。在此推动下，医疗护理器械的开发势头迅猛，但由于各地经济进展的不平衡性以与诸多人为因素的影响，致使许多先进的医护设备得不到应用，给患者带来了许多不便。为了克服这种困难，研制一套功能齐全、造价低廉的护理器械尤为重要，在这种背景下，计算机控制多功能病理床应运而生了。结合病人的需求，设计了一种能自动实现抬头、屈腿、左右侧翻以与同时实现抬头和屈腿等功能的医用多功能病理床。考虑到该病理床要实现各项功能，特将床板分割成八个部分。驱动方式上采纳液压驱动方式，之所以选用液压系统，是因为其运动速度平稳，有用性强。每个动作实现都是由两个液压缸同时直接驱动，上升和下降则通过改变换向阀方向来实现。整个设计分为三步进行：首先设计出能实现动作要求的液压系统原理图，根据要求选择各标准件；其次，进行液压缸体的结构设计与材料的选择；最后，做液压站的总体设计。关键词：液压系统；液压驱动；病理床 AbstractWith the development of medical treatment and the improvement of computers, computer control technique is more and more applied to all kinds of industries, which results the sufferers don’t satisfy traditional medical instruments. Under the impulse of this, the research of medical instruments greatly engages people's attention. But because of the unbalance of regional economic progress and a great deal of factitious factor, many advanced medical instrument are not suitably used, which brings a lot of inconveniences. In order to overcome difficulties, it is more important to study a suit of medical instrument that is multifunctional and cheap, so multifunctional pathological bed controlled by computer comes into being.A kind of multifunction turn-over bed for patients is introduced in this paper, which has the functions of raising head, curling legs, side turning over from left to right separately, or raising head and curling legs a...
