Ko Dialyzer Inogona Kushandiswazve Kurapa Hemodialysis?

Dialyzer, chinhu chakakosha kudyiwa paitsvo dialysis kurapwa, inoshandisa musimboti wesemi-permeable membrane kuunza ropa kubva kune renal kutadza kurwara uye dialysate mudialyzer panguva imwe chete, uye kuita kuti maviri acho ayerera akatarisana kumativi ese iyo dialysis membrane, nerubatsiro rwemativi maviri solute gradient, osmotic gradient, uye hydraulic pressure gradient. Iyi nzira yekuparadzira inogona kubvisa chepfu uye yakawandisa mvura kubva mumuviri ichizadza zvinhu zvinodiwa nemuviri uye kuchengetedza chiyero che electrolytes uye acid-base.

Dialyzers anonyanya kuumbwa nezvimiro zvekutsigira uye dialysis membranes. Iwo hollow fiber marudzi anoshandiswa zvakanyanya mukuita kwekiriniki. Mamwe mahemodialyzer akagadzirwa kuti ashandiswezve, aine mavakirwo akasarudzika uye zvinhu zvinokwanisa kushingirira kucheneswa kwakawanda uye kuvharisa. Zvichakadaro, ma dialyzer anoraswa anofanirwa kuraswa mushure mekushandiswa uye haagone kushandiswa zvakare. Zvisinei, pave nekukakavadzana uye kuvhiringidzika pamusoro pekuti dialyzers inofanira kushandiswa zvakare. Tichaongorora mubvunzo uyu uye topa imwe tsananguro pazasi.

Zvakanakira uye zvakaipira zvekushandisazve dialyzer

(1) Bvisa chirwere chekutanga chekushandisa.
Kunyangwe zvinhu zvakawanda zvichikonzera kutanga-kushandiswa kwechirwere, senge disinfectant ye ethylene oxide, iyo membrane zvinhu, ma cytokines anogadzirwa neropa kusangana kwe dialysis membrane, nezvimwewo, zvisinei kuti chii chinokonzeresa, mukana wekuitika unodzikira nekuda. kudzokororwa kushandiswa kwe dialyzer.

(2) Kuvandudza bio-kuenderana kwe dialyzer uye kuderedza activation ye immune system.
Mushure mekushandisa dialyzer, chidimbu cheprotein firimu chinonamirwa mukati memukati me membrane, iyo inogona kuderedza iyo yeropa firimu rekuita inokonzerwa neanotevera dialysis, uye kuderedza kuzadzisa activation, neutrophil degranulation, lymphocyte activation, microglobulin kugadzirwa, uye cytokine kuburitswa. .

(3) Kupesvedzera kwechiyero chemvumo.
Chiyero chekuchenesa che creatinine uye urea hachidzike. Iyo inoshandiswa zvakare dialyzers ine disinfected ne formalin uye sodium hypochlorite yakawedzerwa inogona kuve nechokwadi chekuti mareti ekubvisa epakati uye makuru mamorekuru zvinhu (Vital12 uye inulin) anoramba asina kuchinjika.

(4) Deredza hemodialysis mari.
Hapana mubvunzo kuti kushandiswazve kwedialyzer kunogona kuderedza mari yehutano yevarwere vane renal kutadza uye kupa mukana kune zvirinani asi zvinodhura hemodialyzers.
Panguva imwecheteyo, zvikanganiso zvekushandisazve dialyzer zviri pachena zvakare.

(1) Kuita kwakashata kune mishonga inouraya utachiona
Peracetic acid disinfection ichaita kuti denaturation uye kuparara kwe dialysis membrane, uye zvakare kubvisa mapuroteni akachengetwa mu membrane nekuda kwekudzokorora kushandiswa, kuwedzera mukana wekuzadzisa activation. Formalin disinfection inogona kukonzera Anti-N-antibody uye ganda allergies muvarwere

(2) Wedzera mukana wekusvibiswa kwebhakitiriya uye endotoxin ye dialyzer uye kuwedzera njodzi yekutapukira.

(3) Kuita kwe dialyzer kunokonzerwa.
Mushure mokunge dialyzer inoshandiswa kakawanda, nekuda kweprotein uye kuvhara kweropa kuvharidzira fiber bundles, nzvimbo inoshanda inoderedzwa, uye chiyero chekuchenesa uye ultrafiltration rate ichaderera zvishoma nezvishoma. Nzira yakajairika yekuyera iyo fiber bundle vhoriyamu ye dialyzer ndeye kuverenga huwandu hwese hwese fiber bundle lumens mu dialyzer. Kana chiyero chehuwandu hwehuwandu kune brand-nyowani dialyzer iri pasi pe80%, dialyzer haigone kushandiswa.

(4) Wedzera mikana yevarwere nevashandi vezvokurapa vari kuratidzwa kune makemikari reagents.
Zvichienderana nekuongorora kuri pamusoro, kuchenesa uye kuuraya hutachiona kunogona kugadzirisa kukanganisa kwekushandisazve dialyzer kusvika pamwero wakati. Iyo dialyzer inogona kushandiswa zvakare mushure mekuchenesa kwakasimba uye disinfection maitiro uye kupasa bvunzo kuti ive nechokwadi chekuti hapana membrane inoputika kana kuvharika mukati. Yakasiyana neyechinyakare dhizaini reprocessing, kushandiswa kweotomatiki dialyzer reprocessing michina inosuma maitiro akamisikidzwa mudhiyalyzer reprocessing kuderedza zvikanganiso mumabasa emaoko. Muchina uyu unogona kungosuka, kuuraya hutachiona, kuyedza, uye kushungurudza, maererano nekumisa maitiro uye paramita, kuvandudza mashandiro edialysis kurapwa, uku uchivimbisa kuchengetedzwa kwemurwere uye hutsanana.
