A i-dialyzer, ngokuvamile eyaziwa ngokuthi izinso zokwenziwa, ibalulekileidivayisi yezokwelaphaesetshenziswa ku-hemodialysis ukuze kukhishwe udoti kanye noketshezi oluningi egazini leziguli ezinokwehluleka kwezinso. Idlala indima ebalulekile enqubweni ye-dialysis, ibuyisela ngempumelelo umsebenzi wokuhlunga wezinso. Ukuqonda ukuthi i-dialyzer isebenza kanjani kanye nezingxenye zayo ezahlukahlukene kubalulekile kubo bobabili ochwepheshe bezempilo neziguli.
Umsebenzi we-Dialyzer ku-Hemodialysis
Owokuqalaumsebenzi we-dialyzerukuhlunga ubuthi, ama-electrolyte, noketshezi oluningi egazini. Phakathi ne-hemodialysis, igazi likhishwa esigulini futhi lidlule ku-dialyzer. Ngaphakathi, igeleza eceleni kolunye uhlangothi lwe-semi-permeable, kuyilapho uketshezi olukhethekile lwe-dialysis (i-dialysate) lugeleza ngakolunye uhlangothi. Lokhu kusetha kuvumela udoti nezinto ezingaphezulu ukuthi zidlule egazini ziye ku-dialysate, kuyilapho kugcinwa izingxenye ezibalulekile njengamaseli egazi namaprotheni.
Izingxenye Eziyinhloko Ze-Dialyzer
Ukuqonda iizingxenye ze-dialyzerisiza ekuqondeni ukuthi isebenza kahle kangakanani. I-dialyzer ejwayelekile iqukethe izingxenye ezilandelayo:
- Izindlu/Izindlu- Igobolondo lepulasitiki eliyicylindrical elifaka izingxenye zangaphakathi.
- I-Fiber Membranes Engenalutho- Izinkulungwane zemicu emincane eyenziwe ngezinto ezikwazi ukungena kalula lapho igazi ligeleza khona.
- Izihloko kanye nezinhlamvu zokugcina– Vikela imicu futhi ulawule ukugeleza kwegazi ukungena nokuphuma ku-dialyzer.
- I-Dialysate Inlet/Outlet Ports- Vumela i-dialysate ukuthi ijikeleze imicu.
Iqhaza Lesihlungi Se-Dialyzer
Iisihlungi se-dialyzeriwulwelwesi olungena kancane ngaphakathi kwe-dialyzer. Yingxenye eyinhloko eyenza kube lula ukushintshana kwezinto phakathi kwegazi ne-dialysate. Izimbotshana zayo ezincane kakhulu zincane ngokwanele ukuvumela i-urea, i-creatinine, i-potassium, noketshezi okweqile ukuthi kudlule, kuyilapho kuvimbela ukulahleka kwezingxenye ezibalulekile zegazi njengamangqamuzana egazi abomvu namaprotheni. Izinga kanye nosayizi wembotshana wolwelwesi lwesihlungi kuthinta ngqo ukusebenza kahle kwe-dialysis.
Izinhlobo ezahlukene ze-Dialyzer
Kukhona ezininganaizinhlobo ze-dialyzeretholakalayo, futhi ukukhetha kuncike esimweni sesiguli, incwadi kadokotela ye-dialysis, nezinjongo zokwelashwa:
- I-Low-Flux Dialyzers- Yiba nezimbotshana ezincane, okuvumela ukususwa okulinganiselwe kwama-molecule; ilungele i-hemodialysis ejwayelekile.
- I-High-Flux Dialyzers- Yiba nezimbotshana ezinkudlwana zokususa ama-molecule aphakathi nendawo; evame ukusetshenziswa ku-dialysis yesimanje ukuze kukhishwe ubuthi obuthuthukisiwe.
- Ama-Dialyzer Asebenza Kakhulu- Yakhelwe ngezindawo ezinkulu ezingaphezulu ukuze ihlunge igazi ngokushesha; isetshenziswa kumaseshini we-dialysis osebenza kahle kakhulu.
- Ukusebenzisa Okukodwa vs. Ama-Dialyzer Asebenziseka Kabusha- Ngokuya ngamaphrothokholi omtholampilo kanye nezindleko, amanye ama-dialyzers ayalahlwa ngemva kokusetshenziswa okukodwa, kuyilapho amanye akhishwa inzalo futhi aphinde asetshenziswe.
Ukukhetha Usayizi We-Dialyzer Ofanele
Usayizi we-dialyzeribhekisela ikakhulukazi endaweni engaphezulu yolwelwesi lwesihlungi kanye nevolumu yangaphakathi ekwazi ukuphatha ukugeleza kwegazi. Indawo engaphezulu isho umthamo omkhulu wokukhipha udoti, okuyenza ifanele iziguli zabantu abadala ezinesisindo somzimba esiphezulu. Iziguli zezingane noma lezo ezinevolumu ephansi yegazi zingadinga ama-dialyzer amancane. Ukukhetha usayizi ofanele kuqinisekisa ukuvunyelwa okuphelele nokuphepha kwesiguli.
Isiphetho: Kungani I-Dialyzer Ibalulekile
I-dialyzer iyinhliziyo yohlelo lwe-hemodialysis, ingena esikhundleni semisebenzi ebalulekile yezinso ezigulini ezinokwehluleka kwezinso. Ngokuqonda okuhlukileizinhlobo ze-dialyzer, izingxenye ze-dialyzer, isihlungi se-dialyzeramakhono, futhi ezifaneleusayizi we-dialyzer, abahlinzeki bezempilo bangathuthukisa izinhlelo zokwelashwa futhi bathuthukise imiphumela yesiguli. Ngokuthuthuka kobuchwepheshe be-membrane kanye nokwakhiwa kwedivayisi, ama-dialyzer ayaqhubeka nokuvela, enikeza ukusebenza kahle nokunethezeka kweziguli ze-dialysis emhlabeni wonke.
