Kodi Dialyzer Ingagwiritsidwenso Ntchito Pochiza Hemodialysis?

Dialyzer, yomwe ndi yofunika kwambiri pochiza matenda a impso, imagwiritsa ntchito mfundo ya nembanemba yomwe ingathe kulowa mkati kuti iwonetse magazi kuchokera kwa odwala omwe ali ndi vuto la aimpso ndikulowa mu dialyzer nthawi yomweyo, ndikupangitsa kuti awiriwo aziyenda molunjika mbali zonse ziwiri. nembanemba ya dialysis, mothandizidwa ndi mbali ziwiri za solute gradient, osmotic gradient, ndi hydraulic pressure gradient. Kubalalika kumeneku kumatha kuchotsa poizoni ndi madzi ochulukirapo m'thupi kwinaku ndikubwezeretsanso zinthu zofunika m'thupi ndikusunga ma electrolyte ndi acid-base.

Ma dialyzer amapangidwa makamaka ndi zida zothandizira ndi nembanemba ya dialysis. Mitundu yopanda kanthu imagwiritsidwa ntchito kwambiri muzachipatala. Ma hemodialyzer ena amapangidwa kuti azigwiritsidwanso ntchito, okhala ndi zomangamanga zapadera komanso zida zomwe zimatha kupirira kutsukidwa kangapo ndi kutsekereza. Pakadali pano, ma dialyzers otayika ayenera kutayidwa akagwiritsidwa ntchito ndipo sangathe kugwiritsidwanso ntchito. Komabe, pakhala mkangano ndi chisokonezo ponena za ngati dialyzer iyenera kugwiritsidwanso ntchito. Tisanthula funso ili ndikupereka kufotokozera pansipa.

Ubwino ndi kuipa kogwiritsanso ntchito ma dialyzer

(1) Kuthetsa matenda oyamba kugwiritsa ntchito.
Ngakhale zinthu zambiri zimayambitsa matenda oyamba kugwiritsa ntchito, monga mankhwala ophera tizilombo toyambitsa matenda a ethylene oxide, nembanemba, ma cytokines opangidwa ndi kukhudzana ndi magazi a nembanemba ya dialysis, etc. kugwiritsa ntchito mobwerezabwereza dialyzer.

(2) Sinthani bio-compatibility ya dialyzer ndikuchepetsa kuyambitsa kwa chitetezo chamthupi.
Pambuyo ntchito dialyzer, wosanjikiza wa mapuloteni filimu Ufumuyo pamwamba pamwamba pa nembanemba, amene akhoza kuchepetsa magazi filimu anachita chifukwa cha dialysis lotsatira, ndi kuchepetsa wowonjezera kutsegula, neutrophil degranulation, lymphocyte kutsegula, microglobulin kupanga, ndi cytokine kumasulidwa. .

(3) Chikoka cha chilolezo cha chilolezo.
Mlingo wa chilolezo cha creatinine ndi urea sikuchepa. Ma dialyzer ogwiritsidwanso ntchito ophera tizilombo toyambitsa matenda ndi formalin ndi sodium hypochlorite yowonjezeredwa amatha kuwonetsetsa kuti chiwongolero cha zinthu zapakatikati ndi zazikulu zama cell (Vital12 ndi inulin) sizisintha.

(4) Kuchepetsa mtengo wa hemodialysis.
Palibe kukayika kuti kugwiritsanso ntchito dialyzer kumatha kuchepetsa ndalama zothandizira odwala aimpso komanso kupereka mwayi wopeza ma hemodialyzer abwinoko koma okwera mtengo.
Panthawi imodzimodziyo, zofooka za kugwiritsanso ntchito dialyzer zikuwonekeranso.

(1) Kuipa kwa mankhwala ophera tizilombo
Peracetic acid disinfection imayambitsa kusokonezeka ndi kuwonongeka kwa nembanemba ya dialysis, ndikuchotsanso mapuloteni omwe amasungidwa mu nembanemba chifukwa chogwiritsa ntchito mobwerezabwereza, ndikuwonjezera mwayi wowonjezera. Formalin disinfection imatha kuyambitsa Anti-N-antibody ndi ziwengo zapakhungu mwa odwala

(2) Wonjezerani mwayi woyipitsidwa ndi bakiteriya ndi endotoxin wa dialyzer ndikuwonjezera chiopsezo chotenga kachilomboka.

(3) Ntchito ya dialyzer imakhudzidwa.
Pambuyo pogwiritsira ntchito dialyzer kangapo, chifukwa cha mapuloteni ndi magazi omwe amatseka mitolo ya fiber, malo ogwira ntchito amachepetsedwa, ndipo chiwerengero cha chilolezo ndi ultrafiltration chidzachepa pang'onopang'ono. Njira yodziwika bwino yoyezera kuchuluka kwa fiber bundle ya dialyzer ndiyo kuwerengera kuchuluka kwa ma lumens a fiber bundle mu dialyzer. Ngati chiŵerengero cha mphamvu zonse ku dialyzer yatsopano ndi yosakwana 80%, dialyzer singagwiritsidwe ntchito.

(4) Wonjezerani mwayi wa odwala ndi ogwira ntchito zachipatala kuti awonetsedwe ndi mankhwala opangira mankhwala.
Kutengera kusanthula pamwambapa, kuyeretsa ndi kupha tizilombo toyambitsa matenda kumatha kubweretsa zolakwika zogwiritsanso ntchito zida zoyatsira pamlingo wina. Dialyzer itha kugwiritsidwanso ntchito pambuyo poyeretsa mosamalitsa ndi njira zophera tizilombo toyambitsa matenda ndikuyesa mayeso kuti zitsimikizire kuti palibe kuphulika kwa membrane kapena kutsekeka mkati. Mosiyana ndi kukonzanso kwapamanja kwachikale, kugwiritsa ntchito makina opangira ma dialyzer kumabweretsa njira zokhazikika pakukonzanso kwa dialyzer kuti muchepetse zolakwika pamachitidwe apamanja. Makinawa amatha kutsuka, kupha tizilombo toyambitsa matenda, kuyesa, ndikuyesa, kutengera njira ndi magawo, kuti apititse patsogolo mphamvu ya chithandizo cha dialysis, ndikuwonetsetsa chitetezo cha odwala komanso ukhondo.
