The Research And Design Of Semiautomatic Clinic Analyzer

As an important analyzer in medical diagnosis, clinic analyzer can measure dozens of biochemical items. Analyze with other diagnosis data, correctly estimation to patient's organ can be got, and it is also well useful to decision of how to cure for patient aftertime.Although precision demand in diagnosis is basically met and has advantage of low price, semiautomatic climc analyzers developed by domestic companies are on a low level still. Firstly, it has possible to make data in chaos because management system has no group build function. Secondly, operation on analyzer is not convenience. At last, doctors can not observe history of patient's condition on traditional analyzer for there is no mass storage unit on it. Automatic clinic analyzers from abroad have an obvious advantage on areas mentioned above, but most of our fellow countryman can not afford the test charge on them for their too expensive price.Aimed at automatic climc analyzers' advantage on management and low price, this paper presents a new semiautomatic clinic analyzer which has a measure circuit based on microprocessor and a management system on personal computer.This paper introduced the principium of clinic analyzer firstly;then DJ9300 semiautomatic clinic analyzer's overall structure and work flow is presented. The analyzer's hardware modules which have fundamental abilities and good results are researched in this paper later. On these hardware modules, multifunctional management software which has automatic clinic analyzers' management ability is researched. And this analyzer's precision is improved for that Grubbs' test is applied in this system. Furthermore, based on ISO standard, 3S quality control atlas which can help us to control this analyzer's quality is applied on it, an important step forward quality control is made by this way.
