Ingabe i-dialyzer ingaphinde isetshenziswe kabusha ukwelashwa kwe-hemodialysis?

I-Dialyzer, ibalulekile ekwamukeleni ukwelashwa kwe-dialysis yezinso, isebenzisa umgomo wolwelwesi olungavunyelwene khona ukwethula iziguli ze-membrane ngasikhathi sinye, ngosizo lwezinhlangothi zombili ze-solute, i-osmotic gradient. Le nqubo yokuhlakazeka ingasusa ubuthi kanye namanzi amaningi emzimbeni ngenkathi igcwalise izinto ezidingekayo zomzimba futhi ilondoloze ibhalansi yama-electrolyte nesisekelo se-acid.

Ama-dialyzers ikakhulukazi akhiwa izinhlaka zokusekelwa kanye nama-dealysis membranes. Izinhlobo eziyize eziyize zisetshenziswa kakhulu ekusebenzeni kwemitholampilo. Ezinye i-hemodialyezers zenzelwe ukusebenza kabusha, ngokwakhiwa okukhethekile nezinto zokwakha ezingamelana nokuhlanzwa okuningi nokuzinza. Okwamanje, amadili anciphayo kufanele alahlwe ngemuva kokusetshenziswa futhi akwazi ukusetshenziswa kabusha. Kodwa-ke, kube nengxabano nokudideka ngokuthi abazidlayo kufanele baphinde basebenzise. Sizohlola lo mbuzo futhi sinikeze incazelo engezansi.

Izinzuzo kanye nokubi kwama-dialyer aphinde ahlolwe kabusha

(1) Susa i-syndrome yokusetshenziswa kokuqala.
Yize izici eziningi zibangela i-syndrome yokusetshenziswa kokuqala, njengokubulala amagciwane e-ethylene oxide, impahla ye-membrane, ama-cytokines akhiqizwa ngokuxhumana kwegazi kohlelo lwe-membrane, njll.

(2) Thuthukisa ukuhambisana kwe-bioly ye-dialyzer futhi kunciphise ukusebenza kwamasosha omzimba.
Ngemuva kokusebenzisa i-dialyzer, ungqimba wefilimu yamaprotheni unamathiselwe endaweni yangaphakathi yolwelwesi, olunganciphisa ukusabela kwefilimu elibangelwa i-dialysis elilandelayo, futhi adambise ukusebenza, ukukhiqizwa kwe-lymphoculin, ukukhiqizwa kwe-cytokine, nokukhishwa kwe-cytokine.

(3) Ithonya lokuthola isilinganiso semvume.
Izinga lokuthola imvume le-creatinine ne-urea alinciphi. Ama-dialyzers aphindaphinde abulawa amagciwane nge-formalin ne-sodium hypochlorite angaqinisekisa ukuthi amazinga okuthola imvume yezinto eziphakathi nezikhulu ze-molecular (vital12 ne-Inulin) zihlala zingashintshiwe.

(4) Yehlisa izindleko ze-hemodialysis.
Akungatshazwa ukuthi ukusetshenziswa kwe-dialyzer kunganciphisa izindleko zokunakekelwa kwezempilo zokuthola iziguli ze-renal ukwehluleka futhi zinikeze ukufinyelela kwe-hemodialyer ebizayo kodwa ebizayo
Ngasikhathi sinye, ukushiyeka kokusebenzisa kabusha kwe-dialzer nakho kusobala.

(1) Ukuphendula okunamandla kokubulala amagciwane
I-Peracetic acid disinfection izodala ukungcola nokubola kosuku lwe-membrane, futhi ikhiphe amaprotheni agcinwe ku-membrane ngenxa yokusetshenziswa okuphindaphindiwe, andise amandla okusebenza okuphindaphindiwe. I-formalin disinfection ingadala i-anti-n-antibody kanye nokungezwani kwesikhumba ezigulini

(2) Khulisa ithuba lokungcoliswa kwegciwane kanye ne-endotoxin ye-diarzer futhi wandise ubungozi bokutheleleka

(3) Ukusebenza kwe-dialyzer kuthonywa.
Ngemuva kokuthi i-dialyzer isetshenziswa kaninginingi, ngenxa yamaprotheni kanye nama-cloots egazi avimba izinqwaba zefayibha, indawo esebenzayo incishisiwe, futhi izinga lokuthola imvume kanye nezinga le-ultrafilstration lizokwehla kancane. Indlela ejwayelekile yokulinganisa ivolumu ye-fiber tunge ye-dialyzer ukubala inani eliphelele lazo zonke izinqwaba ze-fiber linduns ku-dialyzer. Uma isilinganiso sesikhundla esiphelele se-dialyzer entsha sha singaphansi kwama-80%, i-dialyzer ayikwazi ukusetshenziswa.

(4) Khulisa amathuba eziguli kanye nabasebenzi bezokwelapha bevezwa ama-reagents amakhemikhali.
Ngokusekelwe ekuhlaziyweni okungenhla, ukuhlanza kanye namagciwane kungenza ukushiyeka kwama-dialyzers aphinde aphinde ahlolwe ngezinga elithile. I-Dialyzer ingasetshenziswa kuphela ngemuva kokuhlanza okuqinile nokuhlanza izinqubo zokubulala amagciwane futhi idlule izivivinyo zokuqinisekisa ukuqhekeka kukalwelwesi noma ukuvimba ngaphakathi. Okuhlukile kokuphindiselwa kwencwajana yendabuko, ukusetshenziswa kwemishini ye-dialyzer ephindaphindwayo ye-DIALYzer kwethula izinqubo ezijwayelekile ekuvuseleleni amadoriji ukunciphisa amaphutha ekusebenzeni ngesandla. Umshini ungahlambulula ngokuzenzakalela, uthathe amagciwane, uhlole, futhi usebenzise, ​​ngokusho izinqubo namapharamitha, ukuze uqinisekise umphumela wokulashwa kwe-dialysis, ngenkathi uqinisekisa ukuphepha kweziguli kanye nenhlanzeko.
