Abstract:
The combination of biochemistry analyzer and medical expert system was proposed in this report. Biochemistry analyzer is one of the most important analytical instrument used in clinical detection. It could take immunological examination and biochemical analysis for blood, urine, pleural effusion and cerebrospinal fluid and other body fluids. Medical expert system is an intelligent program system with knowledge and experience of a large number of medical specialists. It could use the knowledge and method of medical experts to solve and deal with problems in the field. This system mainly includes human interface, inference engine, interpreter, knowledge acquisition procedures, integrated database and knowledge base. Some parts of system design, such as the expression and design, and interpretation mechanism of the knowledge base, have been interpreted in details. It adopts production as an expression of knowledge. Generally, knowledge was expressed as if the conditions, then the conclusion form. Interpretation mechanism use the error counter propagation of neural network to train the algorithm (BP algorithm for short).The combination could automatically conduct comprehensive analysis of various data generated by the instruments, and then obtain the science theoretical foundation and the most reasonable specialist conclusions. This report provides an overview of the system design of medical expert system.
