Hauv cov khoom siv kho mob thoob ntiaj teb, daim ntawv hla tebchaws rau cov khoom lag luam tsis yog daim ntawv cog lus ua lag luam nkaus xwb, tab sis cov txheej txheem zoo thiab kev ua raws cai tau tsim los ntawm cov qauv thoob ntiaj teb, cov cai hauv cheeb tsam, thiab cov kev cai kho mob. Raws li Chav Kawm III cov cuab yeej kho mob, AVF koob yog raug rau kev saib xyuas nruj heev nyob rau txhua qhov kev sib txuas ntawm cov khoom siv, los ntawm kev yuav khoom raw mus rau daim ntawv thov kho mob zaum kawg. Kev nkag siab thiab kov yeej cov teeb meem no yog qhov yuav tsum tau ua ua ntej rau cov lag luam koom nrog hauv kev sib tw thoob ntiaj teb.

Lub hauv paus tseem ceeb teeb meem nyob rau hauv cov khoom specifications thiab biocompatibility. Raws li cov ntaub ntawv, AVF koob feem ntau yog ua los ntawm 304 lossis 316L kho mob- qib stainless hlau. Nyob rau hauv lub ntiaj teb no cov saw hlau, kev muab cov khoom siv no yog qhov nyuaj dua li kev yuav cov hlau zoo tib yam. Cov neeg muag khoom yuav tsum muab cov ntaub ntawv pov thawj tiav thiab cov ntaub ntawv tshawb xyuas kom paub tseeb tias txhua cov khoom siv ua raws li ASTM lossis ISO kev kho mob - qib specifications. Qhov tseem ceeb tshaj, cov koob tiav lawm yuav tsum tau txais kev soj ntsuam biocompatibility raws li ISO 10993 series qauv, xyuas kom tsis muaj kev pheej hmoo ntawm cytotoxicity, rhiab heev, lossis khaus ntawm tib neeg kev sib cuag. Qhov kev ntsuam xyuas no yog thoob ntiaj teb lees paub los ntawm cov neeg tswj hwm thoob ntiaj teb suav nrog US FDA, EU MDR, thiab Tuam Tshoj NMPA, tsim thawj qhov tseem ceeb rau kev xa khoom nkag.

Thib ob, kev tswj hwm kev tswj hwm kev pov thawj zoo ua haujlwm nruj rau kev sib koom tes ntawm cov khoom siv sib koom tes. ISO 9001: 2015 (Quality Management Systems) thiab ISO 13485: 2016 (Kev Tswj Xyuas Khoom Siv Kho Mob Zoo) yog cov pov thawj lees paub thoob ntiaj teb ntawm cov neeg ua haujlwm muaj peev xwm. Tshwj xeeb tsim los rau kev lag luam khoom siv kho mob, ISO 13485 hais txog kev tswj hwm kev pheej hmoo, kev tsim qauv, kev siv tau zoo, thiab tag nrho traceability. Txhawm rau nkag mus rau cov kev lag luam tseem ceeb xws li Europe thiab North America, AVF koob manufacturers yuav tsum tsim thiab txhawb nqa ISO 13485-raws li qhov system thiab dhau qhov kev tshuaj xyuas los ntawm lub cev muaj cai. Qhov no xav tau kev tswj hwm kev muaj peev xwm tshaj li tsuas yog kev tsim khoom muaj peev xwm, ua kom muaj kev tswj hwm tag nrho los ntawm kev lees txais cov khoom xa tuaj thiab tso lub hauv paus rau kev ntseeg siab nrog cov neeg siv khoom thoob ntiaj teb.

Tsis tas li ntawd, cov qauv kev ua tau zoo ntawm cov khoom lag luam tsim kev lag luam teeb meem. Cov yam ntxwv tseem ceeb ntawm cov koob xws li kev nkag mus rau lub zog, kev nruj, kev sib tsoo toughness, thiab corrosion kuj yog tswj hwm los ntawm cov qauv thoob ntiaj teb sib xws (xws li ISO 7864 rau sterile hypodermic koob) thiab kev lag luam- paub txog txoj kev sim. Cov neeg siv khoom nyob hauv ntau lub teb chaws thiab cheeb tsam tuaj yeem tsim cov kev xeem nruj dua. Cov neeg tsim khoom hauv cov saw hlau yuav tsum tau nruab nrog cov chaw soj ntsuam uas tsim nyog thiab muaj peev xwm ua tau zoo los txheeb xyuas cov khoom lag luam tsis tu ncua. Kev tswj hwm lub zog ntawm cov lus qhia ntawm rab koob polished nyob rau hauv 50-100 grams thiab ua cov kev ntsuam xyuas ntawm ASTM F3014-14, raws li tau hais hauv cov ntaub ntawv kev tshaj lij, yog ib qho kev coj ua kom tau raws li cov qauv kev ua tau zoo.

Yog li ntawd, kev sib tw nyob rau hauv lub ntiaj teb no AVF koob muab saw hlau yog ib tug loj kev sib tw nyob rau hauv lub loj hlob ntawm zoo thiab ua raws li systems. Cov tuam txhab lag luam nrog cov ntawv pov thawj zoo, cov txheej txheem nruj nruj, thiab muaj zog hauv - lub peev xwm kuaj hauv tsev tuaj yeem pab cov neeg siv khoom thoob ntiaj teb kev lag luam zoo dua, txo cov kev pheej hmoo nkag mus rau hauv kev lag luam thiab cov nqi sij hawm. Rau cov neeg yuav khoom, kev tshuaj xyuas ntawm tus neeg muag khoom qhov zoo thiab kev ua raws cai yog feem ntau sib npaug tseem ceeb raws li kev ntsuas cov nqi khoom thiab kev ua haujlwm. Qhov kev hloov pauv no ua rau tag nrho cov khoom xa khoom hloov mus rau qhov pom tseeb dua, kev tsim qauv, thiab kev ntseeg tau.
