USING 3D PRINTING TECHNOLOGY TO FULL-SCALE SIMULATION OF THE UPPER RESPIRATORY TRACT
The project "Implementation of rapid prototyping for modelling the upper respiratory tract in normal and typical pathologies" investigates the urgent problem of improving the reliability of diagnosis and effectiveness of treatment of disorders of the nasal breathing. Possibilities of modern 3D-printing technology for creation of individual natural anatomical models of the upper respiratory tract and determination of their aerodynamic characteristics are considered. The characteristics of the laminar boundary layer of the air flow in the parietal region of the nasal cavity are investigated under different modes of breathing in normal and with typical disorders of the nasal breathing. The concept of investigation of the aerodynamic indices of the anatomical structures of the respiratory system by the results of test tests of individual full-scale 3D models, obtained by the data of spiral computed tomography, is being developed. Theoretical bases of the method of computer planning of restorative rhinosurgical interventions in patients with chronic diseases of the nasal cavity are grounded, based on the change of the configuration of the anatomical structures of the nasal cavity taking into account the aerodynamic parameters of respiration. Modern distance learning and testing tools are being created to demonstrate the technology developed, to provide theoretical knowledge, practical skills and to solve situational tasks for a wide range of specialists. Development and research of natural patterns of the upper respiratory tract allows for supplementing and expanding the knowledge about the aerodynamic characteristics of the nasal cavity, to make decisions about therapy in a short period of time. Experience of the Laboratory of the Institute for Multiphase Processes (IMP) of the Leibniz Universität Hannover (LUH) in the development and use of rapid prototyping capabilities in biotechnology will provide technical support to the project.
