Umhlahlandlela Ophelele Wamazinga Amazwe Ngamazwe, Ububanzi, Nezinzuzo
Imishini yezokwelapha idlala indima ebalulekile ekunakekelweni kwezempilo, isiza odokotela ukuthi bahlonze, belaphe futhi baqaphe iziguli.Kodwa-ke, lapho izinto zezokwelapha zingavalwanga inzalo ngendlela efanele, zingabeka engcupheni enkulu ezigulini ngokudlulisela amagciwane ayingozi, amagciwane, namanye amagciwane.Ukuze kuqinisekiswe ukuphepha kwemishini yezokwelapha, abakhiqizi kufanele bahambisane nemithetho eqinile yokuvala inzalo.Kulesi sihloko, sizoxoxa ngamaleveli amathathu okungasebenzi kwemishini yezokwelapha, ububanzi obuhambisanayo, kanye nezindinganiso zamazwe ngamazwe eziwachazayo.Sizophinde sihlole izinzuzo zezinga ngalinye nokuthi ziqinisekisa kanjani ukuphepha kwemishini yezokwelapha.
Ayini amazinga amathathu okuba sterility?
Amaleveli amathathu okungasebenzi kwemishini yezokwelapha yilawa:
Oyinyumba: Umshini oyinyumba awunawo wonke ama-microorganisms asebenzayo, okuhlanganisa amagciwane, amagciwane, isikhunta, nezinhlamvu.Ukuvala inzalo kutholakala ngezindlela ezihlukahlukene, okuhlanganisa umusi, igesi ye-ethylene oxide, nemisebe.
Ukubulala amagciwane kwezinga eliphezulu: Umshini okhishwa amagciwane ezingeni eliphezulu alinawo wonke ama-microorganisms ngaphandle kwenani elincane lama-bacterialspores.Ukubulala amagciwane kwezinga eliphezulu kufinyelelwa ngezibulali magciwane zamakhemikhali noma inhlanganisela yezibulala-magciwane zamakhemikhali nezindlela ezibonakalayo ezifana nokushisa.
Ukubulala amagciwane kweleveli emaphakathi: Idivayisi efakwa ezingeni eliphakathi nendawo yokubulala amagciwane ayinawo amagciwane amaningi, okuhlanganisa amagciwane, amagciwane, nesikhunta.Ukubulala amagciwane ezingeni eliphakathi kufinyelelwa ngezibulali magciwane zamakhemikhali.
Amazinga wamazwe ngamazwe encazelo yamazinga amathathu okuba sterility
Izinga lamazwe ngamazwe elichaza amazinga amathathu okuvalwa kwedivayisi yezokwelapha yi-ISO 17665. I-ISO 17665 icacisa izidingo zokuthuthukiswa, ukuqinisekiswa, nokulawulwa okujwayelekile kwenqubo yokuvala inzalo kumishini yezokwelapha.Iphinde inikeze isiqondiso ekukhetheni indlela efanele yokuvala inzalo ngokusekelwe kokubalulekile kwedivayisi, idizayini, nokusetshenziswa okuhlosiwe.
Amaleveli amathathu okuba sterility ahambisana nabuphi ububanzi?
Ububanzi bamaleveli amathathu wobunyumba bedivayisi yezokwelapha yilaba:
Oyinyumba: Umshini oyinyumba uneleveli yokuqinisekisa ukuvuthwa (SAL) ka-10^-6, okusho ukuthi kunethuba elilodwa esigidini sokuthi i-microorganism ephilayo ibe khona kudivayisi ngemva kokuvalwa inzalo.
Ukukhishwa kwamagciwane kwezinga eliphezulu: Idivayisi ekhishwa amagciwane kwizinga eliphezulu inokwehliswa kwelogi okungenani okungu-6, okusho ukuthi inani lama-microorganisms kudivayisi lincishiswa nge-factor yesigidi esisodwa.
Ukubulala amagciwane kweleveli emaphakathi: Idivayisi ekhishwa amagciwane ezinga eliphakathi inokwehliswa kwelogi okungenani okungu-4, okusho ukuthi inani lama-microorganisms kudivayisi lincishiswa ngenani lezinkulungwane eziyishumi.
Izinzuzo zamaleveli amathathu wokuba sterility
Amaleveli amathathu okwenziwa kwemishini yezokwelapha aqinisekisa ukuthi izinto zezokwelapha azinawo amagciwane ayingozi, anciphisa ingcuphe yokutheleleka kanye nokusulelana ngokwehlukana.Imishini ebulalayo isetshenziselwa izinqubo zokuhlasela, njengokuhlinzwa, lapho noma yikuphi ukungcola kungabangela izifo ezinzima.Ukubulala amagciwane okusezingeni eliphezulu kusetshenziselwa izinto ezibaluleke kakhulu, njengama-endoscopes, ahlangana nolwelwesi lwamafinyila kodwa angangeni kuwo.Ukubulala amagciwane kweleveli emaphakathi kusetshenziswa kumadivayisi angabalulekile, njengama-cuffs womfutho wegazi, ahlangana nesikhumba esiphelele.Ngokusebenzisa amazinga afanelekile okuvala inzalo, ochwepheshe bezokwelapha bangaqinisekisa ukuthi iziguli zivikelekile kumagciwane ayingozi.
Isifinyezo
Kafushane, amaleveli amathathu okwenziwa kwedivayisi yezokwelapha ayinyumba, izinga eliphezulu lokubulala amagciwane, kanye nokubulala amagciwane okuleveli emaphakathi.Lawa mazinga aqinisekisa ukuthi izisetshenziswa zezokwelapha azinawo ama-microorganisms ayingozi futhi zinciphisa ingozi yokutheleleka kanye nokungcoliswa kwezifo ezihlukahlukene.I-ISO 17665 izinga lamazwe ngamazwe elichaza izidingo zokuthuthukiswa, ukuqinisekiswa, nokulawulwa okujwayelekile kwenqubo yokuvala inzalo yamadivayisi ezokwelapha.Ububanzi bamaleveli amathathu obunyumba buhambisana ne-SAL ka-10^-6 yamadivayisi angenalutho, ilogu encishisiwe okungenani engu-6 yokukhishwa kwamagciwane kwezinga eliphezulu, kanye nokwehliswa kwelogi okungenani okungu-4 kokukhishwa kwamagciwane kweleveli emaphakathi.Ngokunamathela emazingeni afanelekile okuvalwa inzalo, ochwepheshe bezokwelapha bangaqinisekisa ukuthi iziguli zivikelekile kumagciwane ayingozi, futhi nemishini yezokwelapha iphephile ukuthi ingasetshenziswa.
