NEW PARADIGMS IN DESIGNING THE MEDICAL TEXTILES

Abstract

Foreign bodies penetrating deep into the wound at the time of tissue damage can cause chronic inflammatory responses that delay healing and can sometimes lead to the formation of granuloma or abscess. In general, a product intended for the treatment of gunshot wounds must be hypoallergenic, non-toxic and biocompatible; be able to prevent microbial contamination, to enable the gas exchange and exudate evacuation; to be flexible and adaptable to body contours; to be able to deliver, with the appropriate kinetics, important therapeutic compounds for the healing process and to be adherent. The researches were focused on performing of coupled simulations of the human body anatomy, analyse of the impact of the military weapons with different ballistic performances against human body, mathematical modeling of the electrospinning process and definition of the textile mesh parameters. The design of the technological process for obtaining the textile structures used in particular case, was performed, with the help of a dedicated software, the simulation of the main areas of interest of the human anatomy, respectively: the circulatory, bone and muscular system. The results of the simulations enabled the description of the phenomena that take place on the human body subject to the action of the 5.45 x 39 mm infantry armament at subsonic speeds and the mathematical model allowed the prediction of the control of the mesh permeability and of the neo tissue cellular growth and proliferation.
