Izesekeli ze-ECMO System Breathing ze-ECMO "amaphaphu okufakelwa" okokusebenza
I-ECMO, noma i-extracorporeal membrane pulmonary oxygenation, iyindlela esekela ukuphila esebenzisa umshini wokwenziwa okhethekile ukuze ikhiphe igazi enhliziyweni, ishintshisane ngegesi, ilungise izinga lokushisa layo futhi ilisefe ibuyele emithanjeni yomzimba. I-ECMO njengamanje iyindlela eyinhloko yokweseka ukwehluleka okukhulu kwe-cardiopulmonary futhi iye yachazwa "njengendlela yokugcina" yeziguli ezinenyumoniya ye-neocoronary enzima.
Imishini eyisisekelo yomshini wokwenziwa wenhliziyo-amaphaphu ihlanganisa
(1) Iphampu yegazi: Ingxenye eyinhloko yokushayela ukugeleza kwegazi eligcwele umoya-mpilo ngendlela eqondile ngaphandle komzimba futhi libuyele emithanjeni yomzimba, emiselela umsebenzi wokugudluzwa kwegazi wenhliziyo.
(2) Ithuluzi lokugeleza kwegazi eline-oxygen unidirectional.
(3) I-Oxygenator: Ikhipha umoya-mpilo egazini le-venous, ikhipha isikhutha, futhi ithatha indawo yamaphaphu ukuze ishintshisane ngegesi.
(4) I-Thermostat: Umshini osebenzisa izinga lokushisa lamanzi azungezayo elinesihlukanisi sensimbi esincanyana ukuze kube ne-thermal conductivity ukwehlisa noma ukuphakamisa izinga lokushisa kwegazi. Ingase ibe khona njengengxenye ehlukile kodwa ihlanganiswe kakhulu ne-oxygenator.
(5) Isihlungi: Idivayisi equkethe isihlungi se-microporous polymeric material, esibekwe kumjikelezo wokuphakelwa kwegazi emithanjeni, esetshenziselwa ukuhlunga ngempumelelo i-micro-thrombi eyakhiwe izingxenye zegazi noma amagesi, njll.
Isici sokuhlunga somshini wamaphaphu okwenziwa we-HENGKO senziwe ngensimbi engagqwali yebanga le-316 enembayo ephezulu yokuhlunga futhi ingahlunga izinhlobo ezahlukahlukene zezinhlayiya ezihlanganisa amagciwane, amagciwane namaconsi amanzi. Inezinzuzo zokungena kahle, ukuhlunga okuhle, ukuvikela uthuli, iphephile, ayinabuthi, futhi ayinaphunga. Usayizi we-pore uklanywe ngokukhethekile futhi usatshalaliswa ngokulinganayo, futhi ungasetshenziswa izikhathi eziningi ngaphandle kokuwashwa. Ivikela umjikelezo wokuphefumula wesiguli ekungcoleni ngegciwane futhi ivimbele izinhlayiya ezinkulu zothuli ukuthi zingangeni emshinini futhi zidale umonakalo.
