Cov Dialyzer puas tuaj yeem rov siv tau rau kev kho mob hemodialysis?

Dialyzer, uas yog ib qho tseem ceeb rau kev kho lub raum dialysis, siv lub hauv paus ntsiab lus ntawm ib tug semi-permeable daim nyias nyias los qhia cov ntshav los ntawm lub raum tsis ua hauj lwm cov neeg mob thiab dialysate rau hauv lub dialyzer tib lub sij hawm, thiab ua rau ob qho tib si ntws nyob rau hauv opposite lus qhia ntawm ob sab. lub dialysis membrane, nrog kev pab los ntawm ob sab solute gradient, osmotic gradient, thiab hydraulic siab gradient. Cov txheej txheem dispersion no tuaj yeem tshem tawm cov co toxins thiab dej ntau dhau ntawm lub cev thaum rov ua kom lub cev xav tau cov tshuaj thiab tswj qhov sib npaug ntawm electrolytes thiab acid-base.

Dialyzers feem ntau yog tsim los ntawm cov qauv kev txhawb nqa thiab cov ntawv lim dej. Hom hollow fiber ntau yog siv rau hauv kev kho mob. Qee cov hemodialyzers yog tsim los siv tau, nrog rau kev tsim tshwj xeeb thiab cov khoom siv uas tuaj yeem tiv taus ntau yam kev ntxuav thiab kom tsis muaj menyuam. Lub caij no, cov dialyzers pov tseg yuav tsum muab pov tseg tom qab siv thiab tsis tuaj yeem rov qab siv dua. Txawm li cas los xij, muaj kev tsis sib haum xeeb thiab tsis meej pem txog seb puas yuav tsum tau siv cov dialyzers. Peb yuav tshawb nrhiav lo lus nug no thiab muab qee qhov kev piav qhia hauv qab no.

Qhov zoo thiab qhov tsis zoo ntawm reuse dialyzers

(1) Tshem tawm cov tsos mob thawj zaug.
Txawm hais tias muaj ntau yam ua rau cov tsos mob thawj zaug, xws li cov tshuaj tua kab mob ntawm ethylene oxide, cov khoom siv membrane, cov cytokines uas ua los ntawm cov ntshav sib cuag ntawm lub tshuab lim dej, thiab lwm yam, tsis muaj teeb meem dab tsi tshwm sim, qhov tshwm sim yuav txo qis vim. mus rau rov siv lub dialyzer.

(2) Txhim kho bio-compatibility ntawm lub tshuab lim dej thiab txo qhov ua kom lub cev tiv thaiv kab mob.
Tom qab siv lub dialyzer, ib txheej ntawm cov yeeb yaj kiab protein txuas mus rau sab hauv ntawm daim nyias nyias, uas tuaj yeem txo cov ntshav zaj duab xis cov tshuaj tiv thaiv los ntawm kev lim ntshav tom ntej, thiab txo qis kev ua kom tiav, neutrophil degranulation, lymphocyte activation, microglobulin ntau lawm, thiab cytokine tso tawm. .

(3) Kev cuam tshuam ntawm kev tshem tawm tus nqi.
Qhov tshem tawm ntawm creatinine thiab urea tsis txo qis. Cov dialyzers rov qab siv tshuaj tua kab mob nrog formalin thiab sodium hypochlorite ntxiv tuaj yeem ua kom ntseeg tau tias qhov kev tshem tawm ntawm cov khoom nruab nrab thiab loj molecular (Vital12 thiab inulin) tseem tsis hloov.

(4) Txo cov nqi hemodialysis.
Tsis muaj qhov tsis ntseeg tias dialyzer rov siv dua tuaj yeem txo cov nqi kho mob rau cov neeg mob lub raum tsis ua haujlwm thiab muab kev nkag tau zoo dua tab sis kim dua hemodialyzers.
Nyob rau tib lub sijhawm, qhov tsis txaus ntawm dialyzer rov siv dua kuj pom tseeb.

(1) Cov tshuaj tsis zoo rau cov tshuaj tua kab mob
Peracetic acid disinfection yuav ua rau lub denaturation thiab decomposition ntawm lub dialysis daim nyias nyias, thiab kuj tshem tawm cov proteins uas khaws cia nyob rau hauv daim nyias nyias vim hais tias rov siv dua, ua rau kom muaj feem ntawm kev ua kom ntxiv. Formalin tshuaj tua kab mob tuaj yeem ua rau Anti-N-antibody thiab tawv nqaij ua xua rau cov neeg mob

(2) Ua kom muaj feem ntawm cov kab mob thiab endotoxin paug ntawm lub tshuab lim dej thiab ua rau muaj kev pheej hmoo ntawm kev sib kis

(3) Kev ua haujlwm ntawm lub tshuab lim dej tau cuam tshuam.
Tom qab siv lub tshuab lim dej ntau zaus, vim tias cov protein thiab cov ntshav txhaws thaiv cov pob khoom fiber ntau, qhov chaw ua haujlwm tau txo qis, thiab tus nqi clearance thiab ultrafiltration yuav maj mam txo. Ib txoj hauv kev los ntsuas cov fiber ntau ntim ntawm lub dialyzer yog xam cov ntim tag nrho ntawm cov fiber ntau lumens hauv lub tshuab lim dej. Yog tias qhov piv ntawm tag nrho lub peev xwm rau lub tshuab lim dej tshiab yog tsawg dua 80%, lub tshuab lim dej tsis tuaj yeem siv.

(4) Ua kom muaj feem ntau ntawm cov neeg mob thiab cov neeg ua haujlwm kho mob raug cuam tshuam rau cov tshuaj reagents.
Raws li kev soj ntsuam saum toj no, kev ntxuav thiab tshuaj tua kab mob tuaj yeem ua rau qhov tsis zoo ntawm cov tshuab lim dej rov qab siv rau qee qhov. Lub dialyzer tsuas tuaj yeem rov qab siv tau tom qab siv cov txheej txheem tu thiab tshuaj tua kab mob nruj thiab dhau cov kev ntsuam xyuas kom tsis txhob muaj cov membrane tawg lossis txhaws hauv. Sib txawv ntawm kev siv phau ntawv rov ua dua tshiab, kev siv cov tshuab dialyzer reprocessing tsis siv neeg qhia cov txheej txheem txheej txheem rau hauv lub tshuab lim dej kom txo tau qhov yuam kev hauv phau ntawv ua haujlwm. Lub tshuab tuaj yeem tuaj yeem yaug, tshuaj tua kab mob, kuaj, thiab cuam tshuam, raws li kev teeb tsa cov txheej txheem thiab cov txheej txheem, txhawm rau txhim kho cov txiaj ntsig ntawm kev lim ntshav, thaum ua kom cov neeg mob muaj kev nyab xeeb thiab huv.
