多功能床的设计
摘要
随着全球人口老龄化速度加快，护理业服务受到了严峻的挑战，医疗系统和社会保 险系统面临着前所未有的压力。为老年患者及行动不便患者服务的护理型病床的需求正 在不断增加。
针对这一现象，本文详细论述了针对缺乏自理能力的老年人以及行动不便的病人而 设计的多功能护理病床的基本结构和功能原理。该病床能够帮助病人实现坐起、屈膝、 翻身、吃饭及排便，解决病人护理过程中的诸多不便，进而增强了我国的护理业服务， 有力地促进了我国医疗保健事业的发展。
本设计本文首先基于人机工程学，对病床的各项功能进行了原理分析、方案选择、 零件尺寸计算以及强度较核，根据相关标准及调研结果，制定了护理床的设计原则，功 能要求及设计指标；完成了护理床本体的总体方案设计。
然后，采用自上而下的方法完成了护理床结构详细设计并给出了全套的设计图。主 要包括总体框架、抬腿部件、抬背部件、翻身部件等功能模块。其中，排便部件极大地 体现了对老年人的关怀。

Abstract
With the accelerated aging of the global population, nursing services industry are facing severe challenges, hea1th systems and social insurance system faces unprecedented pressure・ Mobility for older patients and patients with type care services are increasing the demand for hospital beds・
In response to t his phenomenon, the paper discusses in det ail the lack of self-care ability for the elderly and patients with reduced mobility multi—purpose care beds designed for the basic strueture and functional principles・ The beds can help patients achieve sit, knees, stand up, eat and defecate, patient care process to solve the inconvenience, thus enhancing our country's nursing services industry, vigorously promoted the development of China，s medical care・ Firstly, the design based on ergonomics, on the bed of the principle functions of the analysis, program selection, part size calcula tions and st reng th t han nuclear, according to the releva nt st andards and research resuIts, developed a nursing bed design principles, functional requirements and design specifications; complete body care bed overall design. Then, using the to p-down approach to comple te the det ailed design of the nursing bed st rue ture and gives a full set of design drawings ・ Includes general framework leg parts, lift the back piece, turning parts and other functiona
