Gulyaikhina E.S. Development of a virtual instrument for computer simulation in the field of clinical laboratory diagnostics

Abstract: The subject of research is the process of creating a computer simulation simulating the conducting a clinical laboratory analysis of biological fluids using a biochemical analyzer Stat Fax® 1904+. Particular attention is driven to the components of the training simulator and to the algorithm for work with it. The article presents features of developing the virtual instrument, caused by its teaching assignment, which consist of the different training levels of users of the system and the possibility of incorrect input data. The author proposes to create three types of users and design features of the software to ensure the accuracy of the data and compliance with the algorithm of the virtual appliance. The paper shows stages of making a computer simulator, such as modeling the system, translation of the model and analyzing the results of the development. The author describes concentrations of a substance in a sample simulated by the software and gives the corresponding formulas for calculations. The study presents a flowchart showing the process of operation of the computer program. The geometric design of application forms and functions of the system is based on this flowchart. A computer simulator created can be used in education at the stage of forming practical skills of students as well as raising the level of professionalism of clinical laboratories. The results of the study can be used in creating training simulators not only for biochemical analysis, but also for other areas of professional activities requiring the use of skills in working with high-tech equipment.
