Isingeniso:
Amasethi okumnika i-PVC adlala indima ebalulekile emkhakheni wezokwelapha ngokunikeza indlela ephephile nephumelelayo yokuletha uketshezi nemithi ezigulini.Ukuqinisekisa ukuphepha kwesiguli nokusebenza okuthembekile, kubalulekile ukuba nokuqonda okuphelele kwenqubo yokukhiqiza kanye namazinga ekhwalithi ahlotshaniswa namasethi wokumnika we-PVC.Kulesi sihloko, sizohlola izici ezibalulekile zokukhiqizwa kwesethi yokumnika kwe-PVC futhi sigqamise ukubaluleka kwezinyathelo zokulawula ikhwalithi.
Isigaba 1: Uhlolojikelele lwe-PVC Infusion Set Production
1.1 Ukuqonda Izingxenye
Amasethi okufakwa kwe-PVC ahlanganisa izingxenye ezimbalwa, okuhlanganisa igumbi lokudonsa, isilawuli sokugeleza, inaliti, ishubhu, nesixhumi.Ingxenye ngayinye idlala indima ebalulekile ekuqinisekiseni ukulethwa koketshezi olunembile nokunciphisa ingozi yokungcoliswa.
1.2 Inqubo Yokukhiqiza
Lesi sigaba sizohlinzeka ngesinyathelo ngesinyathelo uhlolojikelele lwenqubo yokukhiqiza yamasethi okufakwa kwe-PVC, kusukela ekukhethweni kwezinto zokusetshenziswa kuya ekuhlanganisweni kokugcina.Sizoxoxa ngokubaluleka kokugcina izinyathelo zokulawula ikhwalithi eziqinile esigabeni ngasinye ukuze siqinisekise ubuqotho bomkhiqizo.
Isigaba sesi-2: Ukulawulwa Kwekhwalithi Ekukhiqizeni Isethi Yokumnika kwe-PVC
2.1 Ukuhambisana Namazinga Okulawula
Sizogcizelela ukubaluleka kokuthobela izindinganiso zokulawula zikazwelonke nezamazwe ngamazwe, njengemihlahlandlela ye-ISO kanye ne-FDA, ukuze siqinisekise ukuphepha nokusebenza ngempumelelo kwamasethi okumnika kwe-PVC.Ukuthola izitifiketi ezidingekayo kanye nokucwaningwa kwamabhuku okuvamile kuzogqanyiswa njengezici ezibalulekile zokugcina ukuthotshelwa kwemithetho.
2.2 Ukuhlolwa Kwempahla Engavuthiwe
Lesi sigaba sizoxoxa ngokubaluleka kokuhlolwa okuqinile kwezinto ezingavuthiwe, njenge-PVC resin, plasticizers, nezithasiselo, ukuze kuqinisekiswe ukuthi ziyahlangabezana nezindinganiso zekhwalithi ezidingekayo.Sizochaza izingozi ezingaba khona ezihlobene nokusebenzisa izinto ezisezingeni eliphansi kanye nomthelela wazo ekuphepheni kwesiguli.
2.3 Ukuhlolwa Komugqa Wokukhiqiza
Sizochaza izindlela ezahlukahlukene zokulawula ikhwalithi ezisetshenziswa phakathi nenqubo yokukhiqiza, okuhlanganisa ukuhlolwa okungaphakathi kwenqubo, ukulinganiswa kwemishini yokuhlola, nokuhambisana nezinqubo ezijwayelekile zokusebenza.Ukugqamisa ukuthi lezi zinyathelo zisiza kanjani ekuhlonzeni ukuchezuka noma ukonakala kusenesikhathi, ngaleyo ndlela kuncishiswe amathuba okuthi imikhiqizo enephutha ifinyelele emakethe, kuzoba into ebalulekile okugxilwe kuyo.
2.4 Ukuvala inzalo nokupakishwa
Ukubaluleka kwezindlela ezifanele zokuvala inzalo kanye nokupakishwa okuyinyumba ekugcineni ubunyumba nobuqotho bamasethi okufakwa kwe-PVC kuzochazwa.Sizoxoxa ngezindlela ezihlukene zokuvala inzalo ezisetshenziswayo, njengegesi ye-ethylene oxide noma i-gamma irradiation, kanye nezinqubo zokuqinisekisa ezikhona ukuze kuqinisekiswe ukusebenza kwazo.
Isigaba 3: Ukuqinisekisa Ikhwalithi Nokuphepha Komkhiqizo
3.1 Ukuhlolwa Kokuqinisekisa Ikhwalithi
Lesi sigaba sizoveza izivivinyo zokuqinisekiswa kwekhwalithi okuhlukahlukene okwenziwa kumasethi wokumnika aqediwe e-PVC, okuhlanganisa ukuhlola ukuvuza, ukunemba kwezinga lokugeleza, nokucijiswa kwenaliti.Ukubaluleka kokuhlolwa kwenqwaba nokuhlaziywa kwezibalo ekuqinisekiseni ikhwalithi engaguquki kuwo wonke ukukhiqizwa kuzogcizelelwa.
3.2 Ukuthobelana Namazinga E-Biocompatibility
Ukubaluleka kokwenza ukuhlolwa kwe-biocompatibility ukuze kuqinisekiswe ukuthi izinto ezisetshenziswa kumasethi wokumnika we-PVC azibeki ubungozi noma ukusabela okubi lapho kuthintana nezicubu zomuntu kuzoxoxwa ngakho.Sizogqamisa ukuhlolwa okuhlukile okwenziwe, okufana ne-cytotoxicity nokuhlolwa kokucasuka.
Isiphetho:
Ngokuqonda inqubo yokukhiqiza nokusebenzisa izinyathelo zokulawula ikhwalithi eziqinile, ochwepheshe bezokunakekelwa kwempilo bangenza izinqumo ezinolwazi lapho bekhetha futhi besebenzisa amasethi wokumnika we-PVC.Ukunamathela ezindinganisweni zokulawula, ukwenza ukuhlola okuqinile, nokusebenzisa izinyathelo eziqinile zokulawula ikhwalithi kubalulekile ekuqinisekiseni ukuphepha, ukwethembeka, nokusebenza ngempumelelo kwamasethi okumnika i-PVC ukuze asetshenziswe kwezokwelashwa.
