20.500.12556/RUL-148975 Izdelava merilne postaje za merjenje delovanja turbinske srčne črpalke Construction of a measuring station for measuring the operation of the turbine heart pump Levi ventrikularni srčni pomožni sistemi uporabljajo turbinsko centrifugalno črpalko LVAD za podporo bolnikom s hudim srčnim odpovedovanjem. Problem obstoječih črpalk LVAD je pomanjkanje regulacije pretoka in tlaka v kratkih časovnih intervalih, kar negativno vpliva na kakovost življenja bolnikov. Magistrsko delo se osredotoča na pregled, klasifikacijo, karakterizacijo turbinskih črpalk LVAD. Delovno karakteristiko črpalke bomo preučili ter testirali odzivnost in sposobnost njenega delovanja pri različnih pogojih. Zasnovali bomo dve merilni postaji – prva za merjenje karakteristike črpalke in druga za simuliranje uporov krvožilnega sistema ter spremljanje odzivnosti črpalke na spremenljiv upor. Cilj raziskave je razvoj nadzornega sistema za turbinske črpalke LVAD, ki bo omogočal natančno in prilagodljivo mehansko cirkulacijsko podporo krvožilnemu sistemu, kar bo izboljšalo rezultate zdravljenja bolnikov. The master's thesis focuses on left ventricular assist devices (LVADs), which use a centrifugal turbine pump to support patients with severe heart failure. The main problem with current LVAD turbine pumps is the lack of flow and pressure regulation in short time intervals hindering patients' quality of life. The thesis includes a review of LVAD turbine pumps, their classification, and clinical applications. It aims to measure the pump's performance characteristics and test its responsiveness under various conditions. Two measurement stations will be designed: one to measure the pump's performance based on rotational frequency and the other to simulate resistances in the circulatory system and monitor the pump's response to variable resistance characteristics. The research's long-term goal is to develop a control system for LVAD turbine pumps, providing precise and adaptive mechanical support to the heart system and improving patient treatment outcomes. črpalka LVAD turbinska centrifugalna črpalka karakteristika črpalke prilagodljiva mehanska podpora regulacija LVAD pump centrifugal turbine pump performance characteristics adaptive mechanical support regulation true false false [Ž.
