Idivayisi yokusiza inhliziyo yokwenziwa (i-VAD) iyithuluzi elisetshenziselwa ukusiza noma ukufaka esikhundleni ukusebenza kwenhliziyo futhi livame ukusetshenziswa ukwelapha iziguli ezinesifo senhliziyo. Kumadivayisi okusiza inhliziyo yokwenziwa,injini engenamgogodlaiyisici esibalulekile esikhiqiza amandla okujikeleza ukuze kukhuthazwe ukugeleza kwegazi, ngaleyo ndlela kugcinwe ukujikeleza kwegazi kwesiguli. Lesi sihloko sizoxoxa ngokuklama nokusetshenziswa kwama-motor angenawo umgogodla kumaphampu egazi okwenziwa.
Okokuqala, ukwakheka kwenjini engenamgogodla kudinga ukucabangela indawo yayo yokusebenza ekhethekile kumaphampu egazi okwenziwa. Njengoba amadivayisi okusiza inhliziyo okwenziwa kudingeka asebenze isikhathi eside, amanjini angenamgogodla kudingeka asebenze kahle, azinzile futhi athembeke. Ngaphezu kwalokho, njengoba ukusebenza kwawo kudinga ukuthintana ngqo negazi, ukwakheka kwenjini engenamgogodla kudinga futhi ukucabangela ukuhambisana kwezinto eziphilayo kanye nezakhiwo zokulwa ne-thrombotic. Ngakho-ke, amanjini angenamgogodla avame ukusebenzisa izinto ezikhethekile kanye nezingubo zokugqoka ukuqinisekisa ukusebenza kwawo okuzinzile isikhathi eside egazini.
Okwesibili, ukusetshenziswa kwama-motor angenawo umgogodla kumaphampu egazi okwenziwa kudinga ukucabangela umthelela wawo ekugelezeni kwegazi. I-motor engenawo umgogodla iqhuba ukugeleza kwegazi ngamandla e-centrifugal akhiqizwa ukujikeleza, ngakho-ke ukwakheka kwayo kudinga ukucabangela ukuphathwa kwegazi ngobumnene ukuze kugwenywe amandla okweqisa okweqile kanye nokucindezela egazini. Ngesikhathi esifanayo, ukusebenza kwe-motor engenawo umgogodla kudinga ukuhambisana nesigqi se-circadian somzimba womuntu ukuqinisekisa ukujikeleza kwegazi okuzinzile nokuphumelelayo.
Ezisetshenzisweni ezisebenzayo, ukwakheka nokusetshenziswa kwama-motor angenawo umgogodla kumaphampu egazi okwenziwa kudinga ukusebenzisana eduze nezinye izingxenye, njengezinzwa nezinhlelo zokulawula. Ngokulawula nokuqapha okunembile, i-motor engenawo umgogodla ingafinyelela ukulawulwa okunembile kokugeleza kwegazi kanye nengcindezi ukuze ihlangabezane nezidingo zeziguli ezahlukene.
Ngamafuphi, ukwakheka nokusetshenziswa kwama-motor angenawo umgogodla kumaphampu egazi okwenziwa kuyinkinga yobunjiniyela eyinkimbinkimbi futhi ebalulekile edinga ukucatshangelwa okubanzi kwezinto zokwakha, ukuhambisana kwezinto eziphilayo, imishini yoketshezi nezinye izici. Ngokuthuthuka okuqhubekayo kobuchwepheshe bezokwelapha, ukusetshenziswa kwama-motor angenawo umgogodla kumadivayisi okusiza inhliziyo okwenziwa kuzothuthukiswa futhi kuthuthukiswe, kuhlinzekwe ukwelashwa okusebenzayo nokuphephile kweziguli ezinesifo senhliziyo.
