Abstract
Diplomová práce se zabývá návrhem inteligentní matrace pro prevenci proleženin. Cílem práce bylo určit a stanovit kontaktní tlak nepřímou metodou pomocí vhodně stanovených výpočtových vztahů. V rešerši byly řešeny pasivní antidekubitní systémy (matrace), pomocí kterých je možné předejít proleženinám vzniklých působením tlaku. Simulací mechanických vlastností bylo možné zobrazit šíření tlaku v polyuretanové pěně. Na základě výsledků simulace byla stanovena hypotéza s návrhem možného postupu stanovení kontaktního tlaku. Nejprve byla stanovena funkcí distribuce napětí. Pomocí tří tenzometrických snímačů (čidel) umístěných v rovině byly určeny silové odezvy při deformaci pěny. Z nich bylo možné stanovit vzdálenost čidla od zdroje napětí. Tyto hodnoty vzdálenosti byly použity pro určení místa působícího tlakového napětí. Na základě zjištěných výsledků bylo možné určit kontaktní tlak bez nutnosti přímého měření v místě kontaktu.
The Diploma thesis deals with the suggestion of the intelligent mattress for the prevention of the decubitus. The aim of this thesis is to determine the contact pressure by using of the indirect method and with a help of the suitable calculating relations. In the summary there were solved the passive anti-decubitus systems due to them is possible to prevent the decubitus. By the simulation of the mechanical qualities it was possible to show the spreading of the pressure in the polyurethane foam. On the basis of the its results it was determined the hypothesis with the suggestion of the possible procedure of determining of the contact pressure. At first the function of distribution of the voltage was determined. By using of this method it was possible to fill the measured values by the curve which describes their addiction on the contact pressure. The force responses by the deformation of the foam were determined by three tensometric sensors which were placed on the flat surface. From these forces was possible to found out the distance of the sensors from the voltage source. These values of the distance were used for determination of the place of the causing pressure voltage. On the basis of the results it was possible to define the contact pressure without the necessity of the direct measurement in the place of the contact.
