20.500.12556/RUL-84205 Principi delovanja in zanesljivost aktivnih medicinskih vsadkov Operational principles and reliability of active medical implants Cilj diplomske naloge je ugotoviti verjetnost brezhibnega delovanja nekaterih pogosto uporabljenih medicinskih vsadkov. Izbrani sta bili dve vrsti vsadkov, in sicer srčni spodbujevalnik ter polžev vsadek. Za osvetlitev problematike rizičnosti naprav so v nalogi opisani koncepti električne stimulacije z različnimi metodami. Navedene so stimulacijske metode in tehnološke izvedbe naprav, ki so danes na voljo pri obeh vrstah obravnavanih naprav. Specifika srčnih spodbujevalnikov je, da sta v praksi in v tem diplomskem delu ločeno obravnavana spodbujevalnik in elektrode, ki služijo za dovajanje električnega stimulusa na steno srčne mišice. Polžev vsadek je obravnavan kot enota, ki ima svoj notranji del, ki je namenjen vgradnji, in zunanjo enoto, ki služi za digitalno obdelavo in prenos zvočnih signalov preko radiofrekvenčne povezave na notranjo enoto. Obe vrsti vsadkov predstavljata tveganje za uporabnika zaradi biokompatibilnosti in morebitnih okužb. Verjetnost brezhibnega delovanja naprav, ki je pogojena s tehnološko izvedbo, analiziramo na podlagi pridobljenih podatkov skladno z metodo, ki jo uporabljajo proizvajalci srčnih spodbujevalnikov in polževih vsadkov. Aim of this thesis is to define the performance reliability of often used medical implants. Two types of implants were chosen, namely a pacemaker and cochlear implant. Rudiments of electric stimulation are described to illuminate the problem of hazard devices, which are using different stimulation methods. Stimulation methods and technological performance of devices that are available today are listed for both types of implants. Pacemaker specifics are, in practice and in this thesis examined separately. Pacemaker as a unit and electrodes, which serve to supply heart muscle with electrical stimuli. Cochlear implant is treated as a device with its internal unit, which is intended to be implanted, and an external unit, which is used for digital processing and transmission of signals via a radiofrequency link to the internal unit. Both types of implants represent a risk to the user due to the biocompatibility and possible infections. The performance reliability, which is conditioned by technological implementation, was analysed on the basis of acquired data in accordance with method used by manufacturers of pacemakers and cochlear implants. medicinski vsadki srčni spodbujevalnik polžev vsadek verjetnost brezhibnega delovanja medical implants pacemaker cochlear implant performance reliability true false false Slovenski jezik Angleški jezik Diplomsko delo 2016-07-19 08:07:30 2016-07-19 08:07:32 2022-08-02 01:02:16 0000-00-00 00:00:00 2016 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 34041 Kolman_Urban_-_Principi_delovanja_in_zanesljivost_aktivnih_medicinskih_vsadkov.pdf Kolman_Urban_-_Principi_delovanja_in_zanesljivost_aktivnih_medicinskih_vsadkov.pdf 1 3E16F9020258519E86C24F15FB0D4DE9 46e3590b4bbe9350cd75bac521806f054086b880eb7dd38bc24131b7e7c6971f df793f53-a1b0-11eb-a523-00155dcfd717 20.500.12556/rul/2c0b19fe-a5d5-48dd-8f53-2125f3ec2631 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=87242 Fakulteta za elektrotehniko 0 0 0
