Hemodialysis - yini le nqubo?

Ukuze ahlanze igazi compounds nitrogen bese electrolyte e amacala uma izinso akakwazi ukubhekana nomsebenzi wabo, hemodialysis isetshenziswa. Hlobo luni inqubo? Yiphathe njalo le "izinso yokufakelwa" - idivayisi ekhethekile ehlanganisa izingxenye ezintathu. Ake sicabangele ngokuningiliziwe lokho okushiwo yinkulumo inqubo.

Hemodialysis - kuyini?

Le nqubo ubizwa nangokuthi ngokukhishwa kobuthi egazini extracorporeal. Leli gama ugcizelela okushiwo inqubo - a filtration zemvelo, okumele kwenziwe yi-izinso, kuqhutshwa ngaphandle komzimba. Exchange izidakamizwa ngokusebenzisa ulwelwesi semipermeable ngokuthi hemodialysis. Kuyini kusukela iphuzu kwamakhemikhali umbono? Ulwelwesi ubizwa wageza nge uhlangothi igazi equkethe electrolyte kanye nemfucumfucu ye-nitrogen. Ngakolunye uhlangothi - the dialysate. Ketshezi ezimbili ukudala i umyela okuhlushwa, ngawo egazini metabolites excreted. Ulrafiltratsiya, okuyinto hemodialysis (ukuthi luyini lolo daba futhi uyini inqubo yomhlangano, sizochaza kamuva kancane) Kwenziwa usebenzisa ama-apharathasi ekhethekile.

"Izinso Artificial"

Le yunithi siqukethe izingxenye ezintathu. Kudivayisi njengoba - ebaluleke kakhulu kubo unikezwa ulwelwesi lulwimi permeable, eyenziwe zokwenziwa impahla noma i-cellulose. Lo msuka obusebenzayo nokunikeza zokuhlunga umzimba imikhiqizo imfucuza kanye ubuthi. Futhi, iyunithi yakhiwa kudivayisi ukusuthisa igazi ngokusebenzisa tube, futhi idivayisi wokulungiselela dialysate. Igazi Ibuye ibe namaprotheni atholakala, ama-bacterium, ama-elementi letinkhulu agcinwe ngu ulwelwesi. Khona babuyela emzimbeni emthanjeni. Igazi dialyzer sidla ngokusebenzisa tube usebenzisa futha roller. Uhlelo nokulinganisa ijubane ukugeleza kwegazi futhi ingcindezi. Uqaphe ngalezi zinkomba udokotela hemodialysis. Iphinde inquma ukubunjwa ikhambi zelashwe - kuye ezingeni electrolyte ku -plasma yegazi, kumele ilungiswe. Ezimweni eziningi, le amabanga lokuhlushwa potassium, ngezinye izikhathi - sodium.

Ubani odinga "izinso yokufakelwa"?

Iziguli zelashwe kuboniswa izifo ezithile, ezifana ezingamahlalakhona ukwehluleka kwezinso, ezinzima utshwala poisoning, ukweqisa izidakamizwa izidakamizwa futhi abanye ubuthi. Ngaphandle zelashwe nesineke ungafa. Ngemva le nqubo, abantu ungaqhubeka ukuphila okuvamile. Izimo ngilifeze ezinye ukopha, isifo sofuba yamaphaphu (ifomu esebenzayo), izimila abulalayo kwengqondo, ukuguga ebukhoneni sikashukela, isifo sokuqina kwemithambo yegazi, i-hepatitis okungamahlalakhona, isifo sokuqina kwesibindi ukwehluleka inhliziyo nezinye izifo ezithize. Hemodialysis is mhlawumbe eyenziwa cishe kathathu ngesonto, ubude bayo - amahora angaba ngu-4. Ungenza lokhu inqubo ngokuhambisana nezinhlelo ezihlukahlukene. Eqinisweni, kuye ngohlobo ulwelwesi esetshenziswa, hemodialysis kungenziwa nsuku zonke noma ukunciphisa inani izinqubo ezimbili ngesonto.
