Ingabe I-Dialyzer Ingasetshenziswa Kabusha Ekwelapheni I-Hemodialysis?
I-Dialyzer, into ebalulekile esetshenziswayo ekwelashweni kwe-dialysis yezinso, isebenzisa isimiso solwelwesi olukwazi ukungena kancane ukwethula igazi elivela ezigulini ezihluleka yizinso futhi ilifake ku-dialyzer ngasikhathi sinye, futhi lenze kokubili kugeleze ngendlela ephambene nhlangothi zombili. ulwelwesi lwe-dialysis, ngosizo lwezinhlangothi ezimbili ze-solute gradient, i-osmotic gradient, kanye ne-hydraulic pressure gradient. Le nqubo yokusabalalisa ingasusa ubuthi namanzi amaningi emzimbeni kuyilapho igcwalisa izinto ezidingekayo zomzimba futhi igcina ibhalansi yama-electrolyte ne-acid-base.
Ama-dialyzer akhiwe ikakhulukazi izakhiwo zokusekela kanye nolwelwesi lwe-dialysis. Izinhlobo ze-fiber ezingenalutho zisetshenziswa kakhulu emisebenzini yomtholampilo. Amanye ama-hemodialyzer aklanyelwe ukuthi aphinde asetshenziswe, anokwakhiwa okukhethekile nezinto ezikwazi ukumelana nokuhlanzwa okuningi nokuvalwa inzalo. Okwamanje, ama-dialyzer alahlwayo kufanele alahlwe ngemva kokusetshenziswa futhi awakwazi ukuphinda asetshenziswe. Kodwa-ke, kube nokuphikisana nokudideka mayelana nokuthi ama-dialyzer kufanele aphinde asetshenziswe yini. Sizohlola lo mbuzo futhi sinikeze incazelo ngezansi.
Izinzuzo kanye nokubi zokusebenzisa kabusha ama-dialyzer
(1) Susa i-syndrome yokusetshenziswa kokuqala.
Nakuba izici eziningi zibangela i-syndrome yokusetshenziswa kokuqala, njenge-disinfectant ye-ethylene oxide, i-membrane material, ama-cytokines akhiqizwa ukuthintana kwegazi kwe-dialysis membrane, njll., kungakhathaliseki ukuthi yiziphi izimbangela, amathuba okuba khona azokwehla ngenxa. ekusebenziseni okuphindaphindiwe kwe-dialyzer.
(2) Thuthukisa i-bio-compatibility ye-dialyzer futhi unciphise ukusebenza kwamasosha omzimba.
Ngemuva kokusebenzisa i-dialyzer, ungqimba lwefilimu yamaprotheni lunamathiselwe endaweni engaphakathi yolwelwesi, olunganciphisa ukusabela kwefilimu yegazi okubangelwa i-dialysis elandelayo, futhi kunciphise ukusebenza komphelelisi, i-neutrophil degranulation, activation lymphocyte, ukukhiqizwa kwe-microglobulin, nokukhululwa kwe-cytokine. .
(3) Umthelela wesilinganiso sokuvunyelwa.
Izinga lokucaciswa kwe-creatinine ne-urea alinciphi. Ama-dialyzer aphinde asetshenziswa abulawe amagciwane ane-formalin ne-sodium hypochlorite engeziwe angaqinisekisa ukuthi amazinga okusula ezinto zamangqamuzana aphakathi nendawo nezinkulu (i-Vital12 ne-inulin) ahlala engashintshile.
(4) Yehlisa izindleko ze-hemodialysis.
Akungabazeki ukuthi ukusetshenziswa kabusha kwe-dialyzer kunganciphisa izindleko zokunakekelwa kwezempilo ezigulini ezihluleka izinso futhi kunikeze ukufinyelela kuma-hemodialyzer angcono kodwa abiza kakhulu.
Ngesikhathi esifanayo, ukushiyeka kokusetshenziswa kabusha kwe-dialyzer nakho kuyabonakala.
(1) Ukusabela okungekuhle kuma-disinfectants
I-Peracetic acid disinfection izodala ukubola nokubola kwe-membrane ye-dialysis, futhi isuse amaprotheni agcinwe kulwelwesi ngenxa yokusetshenziswa okuphindaphindiwe, okwandisa amathuba okuba kusebenze umphelelisi. Ukukhishwa kwe-Formalin kungabangela i-Anti-N-antibody kanye nokungezwani komzimba nesikhumba ezigulini
(2) Khulisa ithuba lokungcoliswa amagciwane kanye ne-endotoxin ye-dialyzer futhi kwandise ingozi yokutheleleka ngegciwane
(3) Ukusebenza kwe-dialyzer kuyathonywa.
Ngemuva kokuthi i-dialyzer isetshenziswe izikhathi eziningana, ngenxa yamaprotheni namahlule egazi avimbela ama-fiber bundles, indawo ephumelelayo iyancishiswa, futhi izinga lokusula kanye ne-ultrafiltration rate izokwehla kancane kancane. Indlela evamile yokulinganisa ivolumu ye-fiber bundle ye-dialyzer iwukubala isamba sevolumu yawo wonke ama-lumens enqwaba yefiber ku-dialyzer. Uma isilinganiso sesamba somthamo we-dialyzer entsha sha singaphansi kwama-80%, isidayeli se-dialyzer asinakusetshenziswa.
(4)Ukwandisa amathuba okuthi iziguli kanye nabasebenzi bezokwelapha bachayeke kuma-reagents amakhemikhali.
Ngokusekelwe ekuhlaziyweni okungenhla, ukuhlanzwa kanye nokubulala amagciwane kungavala ukushiyeka kokuphinda usebenzise ama-dialyzer ngokwezinga elithile. I-dialyzer ingasetshenziswa kabusha kuphela ngemva kwezinqubo eziqinile zokuhlanza nokubulala amagciwane kanye nokuhlolwa okuphasile ukuze kuqinisekiswe ukuthi akukho ukugqashuka kolwelwesi noma ukuvaleka ngaphakathi. Ngokuhlukile ekucubunguleni kabusha okungokwesiko okwenziwa ngesandla, ukusetshenziswa kwemishini yokucubungula kabusha i-dialyzer yethula izinqubo ezimisiwe ekucutshungulweni kabusha kwe-dialyzer ukuze kuncishiswe amaphutha ekusebenzeni okwenziwa ngesandla. Umshini ungahlanza ngokuzenzakalelayo, ukhiphe amagciwane, uhlole, futhi uhlukumeze, ngokusho kwezinqubo zokubeka kanye nemingcele, ukuthuthukisa umphumela wokwelashwa kwe-dialysis, kuyilapho uqinisekisa ukuphepha kwesiguli nokuhlanzeka.
I-W-F168-B
Umshini ka-Chengdu Wesley wokucubungula kabusha umshini wokudayela umshini wokudayela othomathikhi wokuqala emhlabeni ukuze isibhedlela sibulale inzalo, sihlanze, sihlole, futhi sisebenzise kabi isicwecwe sokudayela esisetshenziswa kabusha esisetshenziswa ekwelashweni kwe-hemodialysis, nesitifiketi se-CE, siphephile futhi sizinzile. I-W-F168-B enendawo yokusebenza ekabili ingafeza ukucutshungulwa kabusha emizuzwini eyi-12.
Izinyathelo zokuphepha zokusebenzisa kabusha isidayeli se-dialyzer
Ama-dialyzer angasetshenziswa kabusha esigulini esifanayo kuphela, kodwa izimo ezilandelayo azivunyelwe.
1.Izidayalyza ezisetshenziswa iziguli ezinezimpawu zegciwane le-hepatitis B azikwazi ukuphinda zisetshenziswe; ama-dialyzer asetshenziswa iziguli ezinezimpawu zegciwane le-hepatitis C elihle kufanele akhishwe kwezinye iziguli lapho ephinda esetshenziswa.
2.Ama-dialyzer asetshenziswa iziguli ezine-HIV noma ingculazi ngeke aphinde asetshenziswe
3.Ama-dialyzer asetshenziswa iziguli ezinezifo ezithathelwanayo ezithwala igazi awakwazi ukuphinda asetshenziswe
4. Ama-dialyzer asetshenziswa iziguli ezingazwani nezibulala-magciwane ezisetshenziswa ekucubunguleni azikwazi ukuphinda zisetshenziswe.
Kukhona nezidingo eziqinile zekhwalithi yamanzi ye-hemodialyzer reprocessing.
Izinga lebhaktheriya alikwazi ukudlula i-200 CFU/ml ngenkathi ukungenelela okuboshiwe kungu-50 CFU/ml; izinga le-Endotoxin alikwazi ukweqa i-2 EU/ml. Ukuhlolwa kokuqala kwe-endotoxin namagciwane emanzini kufanele kube kanye ngesonto. Ngemva kwemiphumela yokuhlolwa emibili elandelanayo ihlangabezana nezidingo, ukuhlolwa kwebhaktheriya kufanele kube kanye ngenyanga, futhi ukuhlolwa kwe-endotoxin kufanele kube okungenani kanye ezinyangeni ezintathu.
(Umshini wamanzi we-Chengdu Weslsy's RO uhlangana namazinga amanzi ase-US AAMI/ASAIO dialysis angasetshenziselwa ukucutshungulwa kabusha kwe-dialyzer)
Yize imakethe yokusetshenziswa kwama-dialyzer asebenziseka kabusha ibilokhu yehla unyaka nonyaka emhlabeni wonke, isadingeka kwamanye amazwe nasezifundeni ezinomqondo wayo wezomnotho.
