【摘要】：尿液分析仪是临床检验中不可缺少的医疗工具,它能够准确并且快速地检查出人体尿液的各个重要成份,反应人体的各项生理指标,是医生对患者做出正确诊断的一项重要依据。当前,尿液分析仪已经普遍运用至各个医疗组织之中。尽管市面上的尿液分析仪种类繁多,但是大部分尿液分析仪的使用范围还局限于医疗机构。因而,开发一款可以满足基层社区、广大农村甚至于每家每户而使用的,性能稳定、技术先进、价格实惠、操作简易且基本功能齐全的普及型尿液分析仪,具有重要意义。本文首先对当前尿液分析仪的现状、发展趋向与现存的问题,做了简明介绍,并且以国内外现有尿液分析仪为对象,重点研究其机械构造、检测模式、稳定性、准确度以及信息处理等多个层面,并且在此基础上,确定了所研发的普及型尿液分析仪的基本技术参数需求。在满足基本技术要求的前提下,该尿液分析仪的设计,本着制造成本低、使用成本低、操作简便的原则,达到普及化的目的。其中,根据技术参数要求,完成了普及型尿液分析仪的基本设计,包括尿液分析仪的控制系统、下位机系统、上位机系统、操作界面等等。针对尿液分析仪的工作原理,规划电路体系、简单化电路,并增强系统的信息处理水平以及调控的可靠度。制定了可靠度高的通信协议,完成了上位机对于下位机的调控,使得尿液分析仪能够正常工作。并且对下位机系统的各个模块进行开发,实现尿液分析仪的自动控制。
[Abstract]:Urine analyzer is an indispensable medical tool in clinical testing. It can accurately and quickly check out the important components of human urine and reflect the physiological indexes of human body. Is an important basis for doctors to make a correct diagnosis of patients. At present, urine analyzers have been widely used in various medical organizations. Although there are many kinds of urine analyzers on the market, But the use of most urine analyzers is still limited to medical institutions. Therefore, the development of a urine analyzer that can be used in grass-roots communities, rural areas and even every household has stable performance, advanced technology, and affordable prices. The universal urine analyzer with simple operation and complete basic functions is of great significance. Firstly, the present situation, development trend and existing problems of the present urine analyzer are briefly introduced in this paper. And taking the existing urine analyzer at home and abroad as the object, it focuses on the mechanical structure, detection mode, stability, accuracy and information processing, and on this basis, The basic technical parameters of the developed universal urine analyzer are determined. On the premise of satisfying the basic technical requirements, the design of the urine analyzer is based on the principle of low manufacturing cost, low use cost and simple operation. According to the requirements of technical parameters, the basic design of the universal urine analyzer is completed, including the control system of the urine analyzer, the lower computer system, the upper computer system, Operation interface and so on. Aiming at the working principle of urine analyzer, planning circuit system, simplifying circuit, and enhancing the level of information processing and the reliability of control of the system, the communication protocol with high reliability is established. The control of the upper computer for the lower computer is completed, so that the urine analyzer can work normally, and each module of the lower computer system is developed to realize the automatic control of the urine analyzer.
