A i-dialyzer, eyaziwa ngokuthi yinso yokwenziwa, iyinto ebalulekileidivayisi yezokwelaphaIsetshenziswa ekuhlaziyweni kwegazi ukuze kususwe ukungcola kanye noketshezi oluningi egazini leziguli ezinenkinga yezinso. Idlala indima ebalulekile enqubweni yokuhlanza igazi, ithatha indawo ngempumelelo yomsebenzi wokuhlunga wezinso. Ukuqonda ukuthi i-dialyzer isebenza kanjani kanye nezingxenye zayo ezahlukahlukene kubalulekile kokubili kochwepheshe bezempilo kanye neziguli.
Umsebenzi we-Dialyzer ku-Hemodialysis
Okuyinhlokoumsebenzi we-dialyzeriwukuhlunga ubuthi, ama-electrolyte, kanye noketshezi oluningi oluvela egazini. Ngesikhathi se-hemodialysis, igazi likhishwa esigulini bese lidlula ku-dialyzer. Ngaphakathi, ligeleza ohlangothini olulodwa lwe-membrane engena kancane, kuyilapho uketshezi olukhethekile lwe-dialysate (i-dialysate) lugeleza ngakolunye uhlangothi. Lokhu kusetha kuvumela imfucuza nezinto eziningi ukuthi zidlule egazini ziye ku-dialysate, kuyilapho kugcinwa izingxenye ezibalulekile njengamaseli egazi namaprotheni.
Izingxenye Eziyinhloko Ze-Dialyzer
Ukuqondaizingxenye ze-dialyzerkusiza ekuqondeni ukuthi isebenza kahle kangakanani. I-dialyzer ejwayelekile iqukethe izingxenye ezilandelayo:
- Izindlu/Ikheyisi– Igobolondo eliyindilinga lepulasitiki elihlanganisa izingxenye zangaphakathi.
- Ama-membrane e-Hollow Fiber– Izinkulungwane zemicu emincane eyenziwe ngezinto ezigeleza igazi kancane lapho kugeleza khona igazi.
- Amakhanda kanye nama-End Caps– Vikela imicu futhi ulawule ukugeleza kwegazi ngaphakathi nangaphandle kwe-dialyzer.
- Amachweba Okungena/Okuphumayo e-Dialysate– Vumela i-dialysate ukuthi ijikeleze imicu.
Indima Yesihlungi Se-Dialyzer
Iisihlungi se-dialyzeryi-membrane engena kancane ngaphakathi kwe-dialyzer. Yiyona ngxenye eyinhloko eyenza kube lula ukushintshana kwezinto phakathi kwegazi ne-dialysate. I-pores yayo encane kakhulu mincane ngokwanele ukuvumela i-urea, i-creatinine, i-potassium, kanye noketshezi oluningi ukuthi kudlule, kuyilapho kuvimbela ukulahleka kwezingxenye ezibalulekile zegazi njengamaseli abomvu egazi namaprotheni. Ikhwalithi kanye nosayizi we-pore we-membrane yesihlungi kuthinta ngqo ukusebenza kahle kwe-dialysis.
Izinhlobo Ezihlukene Ze-Dialyzer
Kunezinhlobo ezininganaizinhlobo ze-dialyzerkuyatholakala, futhi ukukhetha kuncike esimweni sesiguli, ukunikezwa kwemithi yokuhlanza igazi, kanye nemigomo yokwelashwa:
- Ama-Dialyzer Aphansi– Zinezimbobo ezincane, okuvumela ukususwa okulinganiselwe kwama-molecule; zilungele i-hemodialysis ejwayelekile.
- Ama-Dialyzer Ahamba Ngokusheshisa– Inezimbobo ezinkulu zokususa kangcono ama-molecule aphakathi; evame ukusetshenziswa ku-dialysis yesimanje ukuze kususwe ubuthi obuthuthukisiwe.
- Ama-Dialyzer Asebenza Kakhulu– Yakhelwe izindawo ezinkulu zokuhlunga igazi ngokushesha; isetshenziswa kumaseshini e-dialysis asebenza kahle kakhulu.
- Ama-Dialyzer Okusetshenziswa Kanye Uma kuqhathaniswa Nama-Reusable– Kuye ngezinqubo zomtholampilo kanye nezindleko, amanye ama-dialyzer alahlwa ngemva kokusetshenziswa okukodwa, kanti amanye ayahlanzwa futhi aphinde asetshenziswe.
Ukukhetha Usayizi We-Dialyzer Ofanele
Usayizi we-Dialyzeribhekisela kakhulu endaweni engaphezulu kwe-membrane yesihlungi kanye nomthamo wangaphakathi ongaphatha ukugeleza kwegazi. Indawo enkulu engaphezulu isho umthamo omkhulu wokususa imfucuza, okwenza ifaneleke ezigulini ezindala ezinesisindo somzimba esiphezulu. Iziguli zezingane noma lezo ezinevolumu encane yegazi zingadinga ama-dialyzer amancane. Ukukhetha usayizi ofanele kuqinisekisa ukususwa okuphelele kanye nokuphepha kwesiguli.
Isiphetho: Kungani i-Dialyzer Ibalulekile
I-dialyzer iyinhliziyo yesistimu ye-hemodialysis, ethatha indawo yemisebenzi ebalulekile yezinso yeziguli ezinenkinga yezinso. Ngokuqonda izindlela ezahlukene zokuhlolaizinhlobo ze-dialyzer, izingxenye ze-dialyzer, isihlungi se-dialyzeramakhono, kanye nokufanelekausayizi we-dialyzer, abahlinzeki bezempilo bangenza ngcono izinhlelo zokwelapha futhi bathuthukise imiphumela yeziguli. Ngokuthuthuka kobuchwepheshe be-membrane kanye nokwakhiwa kwamadivayisi, ama-dialyzer ayaqhubeka nokukhula, enikeza ukusebenza kahle kanye nenduduzo engcono kwiziguli ezidayisa i-dialysis emhlabeni jikelele.
