Zhdanova O. Improvement of barrier fabrication technologies for surgical staff

The thesis is devoted to the technology process improvement of effective modern barrier clothing production with the predicted indicators of reliability and ergonomics for medical workers of surgical wards. The peculiarities of the operating conditions of protective barrier medical surgical clothing, which influence the ergonomics and the term of its operation, have been analyzed. The main dangerous and harmful factors of professional activity have been determined, the topography of the these factors influence on the organism of surgeons, as well as the areas of surgical gown according to different functional loading, has been developed. It has been determined that ensuring safe working conditions, reducing the risk of occupational diseases can be possible due to the zonal selection of materials of surgical clothing and sewing threads for its manufacture, creation of a rational structural device, application of the principles of transformation in the design of individual units and clothing in general. The zonal use of textile materials with different degree of barrier protection in different areas of surgical gown has been scientifically substantiated, which provides the necessary level of comfort with optimal protection of surgeons during operations. The recommendations have been suggested on the selection of rational combinations of protective materials, the use of threads with antimicrobial properties, the choice of rational modes of sealing seams in the design and manufacture of surgical gowns. The influence of operational loading and cleaning conditions of surgical gowns on the physic-mechanical indices of the selected materials and joints of the product has been investigated, which made it possible to form a rational package of materials and to choose the threads with the highest quality indicators for manufacturing surgical gowns of the proposed structural device. The mathematical modeling of the adhesion process of the sealed thread seams components has been performed and the criteria for evaluation of their quality have been determined. The range of products has been developed and art and design solutions for surgical gowns with improved protective and ergonomic parameters have been proposed. Keywords: surgical gown, barrier clothing, medical clothing, zonal application of materials, transformation methods.
