Abstract
To carry out modeling of moisture transfer processes in multilayer medical application materials for forecasting of targeted transport of drugs of a certain effective concentration into the lesion center, based on the geometric parameters of the wounds. Using digital image processing techniques in a computer environment have developed methods for designing three-dimensional fluid propagation effects in multilayer medical wound dressings. Modern wound dressings have been found to be multilayer multidimensional compositions with complex fluid kinetics. Additionally, the wounds on the human body itself have a complex space geometric shape. This requires taking into account the volumetric effects when analyzing and forecasting the processes of wetting and fluid flow in such systems. An algorithm for ordering the boundary of a wound by digital photography with the subsequent processing of a wound image in a computer environment is proposed. To evaluate the moisture transport properties for the controlled release of medicinal substances at the desired concentration in different layers of wound dressings, an experiment was made with wetting from two and three sources, followed by three-dimensional modeling. It has been experimentally found that the parameters of the layered distribution of liquid moisture in multilayer dressings vary significantly.. The results of the simulation are suitable for making prompt decisions about the type, the required geometric parameters of medical materials and wound dressings. The proposed method of establishing the real geometry of the wound, together with three-dimensional modeling, allows to predict the exact boundaries of the application of the drug, to calculate its required amount and time of movement to the wound. Using 3D computer graphics of discrete objects, methods have been developed to predict the conditions for the reliable functioning of multilayer dressings. Investigated processes of transport and distribution of liquid moisture can be used in the selection of components of the raw material composition, structure and number of layers of multilayer wound dressings, taking into account the real geometric profile of the wound.
