Study On The Modular Technique And Design Of Home Ventilator

With the continuous progress of science and technology,the development of economic level,and the continuous progress of the people's health concept,the consumption scope of people is gradually inclined to the big health industry.Medical products play an increasingly important role in it.Some medical devices are also accepted by the masses and play an important role.In recent years,the high incidence of sleep apnea syndrome and the respiratory system problems caused by aging and air environment deterioration are not optimistic.With the increasing demand of the domestic ventilator Market,more and more domestic and foreign household medical industry is committed to the research and development of the domestic ventilator.However,the domestic ventilator technology is lagging behind,the production models are mostly middle and low home ventilator,and the product lacks innovation and homogenization.The application of modular design is a way to solve the problem,which is conducive to the diversification and customization of products.In this paper,the research on the application of the modular design method in the household ventilator is studied.The research background of the paper is fully analyzed from the aspects of environmental change,respiratory health,the development of the household medical device market and the design trend,and the development of the ventilator and the research on the modular design of domestic and foreign scholars are briefly expounded.The purpose and significance of the study are explained.Then the modular design theory is introduced,then the modularized design theory and the related principles and methods are expounded.The theoretical overview shows that the understanding of the relevant theoretical methods will be presented on the basis of the household respirator or other product examples,and the main purpose of the modular design application is to be clear.The effective way to meet the diversification of the product demand and to cope with the rapid upgrading of the product has provided a theoretical basis for the research and analysis of the modular design of the later household ventilator.Then,a chapter is set up to describe the current situation and development of the household ventilator in detail,which focuses on the understanding of the working principle of the ventilator,the analysis of the functional system and the trend of the future design and development,and set up the knowledge base for the application of the later modular design method.In the next part,the modular design of the household ventilator is used to analyze the modular design of the ventilator from top to bottom.The main design process includes the demand analysis,the module division,the product architecture,the design strategy and so on.Finally,in the design practice,the conceptual design of some modules and the overall product scheme is designed for the functional requirements of the household ventilator in the customization level,and the fuzzy comprehensive evaluation method is used for the comprehensive evaluation of the modular design example.
