【摘要】 透析器是治疗慢性肾脏疾病的三类医疗器械,我国患有慢性肾脏疾病的病人有着庞大的数量。透析器生产工艺研究不仅能够带来巨大的经济效益和社会效益,而且对整个透析器行业的发展都有着巨大的意义。B公司是2003年成立的技术领先的血液净化类医疗设备制造商,致力于血液净化设备及耗材的研发、制造和销售,目前主要产品有血液透析器、体外循环管路、穿刺针、血液透析机等。公司目前在全球范围内的销售已覆盖至欧洲、亚洲、中东、非洲和南美等近60多个国家和地区,公司为国内最大、世界五强的血液净化类产品的专业制造商。然而,B公司透析器生产线以半自动化模式为主,在其产品生产效率和产品质量如何改善以应对未来的市场竞争?本文通过对透析器生产工序分析调查,采用正交实验的方法,对透析器离心工艺进行研究,提高生产效率和低生产过程不良率,从而实现低成本透析器。本文详细介绍了透析器的产品组成及生产工艺过程,以及产能瓶颈。文章通过对B公司的生产工序能力分析,说明了各透析器生产工序特点及产品品质要点,并运用正交实验设计方案对B公司离心工艺的关键影响因素进行识别和分析,之后对B公司的透析器离心工序目前存在的问题做了分析、归纳和总结。然后本文从离心温度高低、离心时间长短、离心转速快慢这3个方向,对透析器的注胶离心工艺实验研究,最终得出高效率、低成本、高品质的透析器生产工艺,提高透析器的生产效率,降低生产过程不良率。对优化B公司透析器生产工艺进行分析和整理,本文最后给出了B公司透析器离心工艺优化对策。更多还原

【Abstract】 The dialyzer is the third type of medical equipment for the treatment of chronic kidney disease.There are a huge number of patients with chronic kidney disease.Studying on the production process of dialysis can not only bring huge economic benefits and social benefits,but also has great significance in the development of the whole dialyzer industry.B company is a leading company founded in 2003,who devotes itself to medical equipment of blood purification,and it is committed to R & D,manufacture and sales of blood purification equipment.The main products are haemodialysers,extracorporeal circulation pipeline,puncture needle,blood dialysis machine etc..The company has currently made its global sales coverage to nearly more than 60 countries and regions,including Europe,Asia,Middle East,Africa and South America.The company is the largest professional manufacturer of blood purification products at home,and the world’s top five professional manufacturer.However,the dialyzer production line in B company is in a semi automated mode,how to improve its production efficiency and product quality in order to deal with the market competition in the future? This paper studies the dialyzer centrifugal process to improve production efficiency and product quality,based on the investigation and analysis of dialyzer production process,using the method of orthogonal experiment.This paper introduces the composition of the product and production process of the dialyzer,and capacity bottlenecks.Through the analysis of process capability of B,this paper shows the dialyzer production process and product quality characteristics and key points.After using the orthogonal experimental design to identify and analyze the centrifugal factors effect,the existing centrifugal process problems were analyzed and summarized.This paper studies injection process from the 3 directions of centrifugal temperature,centrifugation time and speed,and finally we obtains a dialyzer production process with high efficiency,low cost and high quality,which improves production efficiency and reduces the non-performing rate.By analyzing and organizing the optimization of dialyzer production process,this paper finally gives the countermeasures to optimize the dialyzer centrifugal process.更多还原
