EO Residual yog dab tsi?
Ethylene oxide (EO) sterilization yog ib qho ntawm kev siv qis tshaj plaws -kub sterilization txoj kev rau cov khoom siv kho mob. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov khoom siv hluav taws xob kub- rhiab heev xws li catheters, syringes, cov khoom siv phais mob, cov khoom ntim cog, thiab cov khoom siv kho mob hluav taws xob.
Tom qab ua kom tsis muaj menyuam, me me ntawm EO roj thiab nws cov tshuaj tiv thaiv los ntawm cov khoom yuav nyob hauv cov khoom thiab cov khoom ntim. Cov tshuaj no feem ntau hu ua EO residuals thiab tej zaum yuav suav nrog Ethylene Oxide (EO), Ethylene Chlorohydrin (ECH), thiab Ethylene Glycol (EG).
Vim tias cov khoom seem seem tuaj yeem nyob twj ywm hauv cov polymers, foams, ntev lumens, thiab cov txheej txheem ntim ntau, cov khoom seem yuav yog ib feem tseem ceeb ntawm tag nrho cov txheej txheem kom tsis muaj menyuam.
Vim li cas EO Residual Control tseem ceeb
Lub hom phiaj ntawm EO sterilization tsis yog tsuas yog ua kom tiav microbial inactivation tab sis kuj los xyuas kom meej tias cov seem seem raug txo kom tau txais kev txwv ua ntej cov khoom raug tso tawm rau kev kho mob. Residual tswj pab manufacturers:
Biocompatibility:Ua raws li ISO10993 biocompatibility cov cai
Risk txo:Txo cov khoom tso tawm txaus ntshai
Kev sib raug zoo:Txhim kho cov txheej txheem sib xws
Ua raws li:Txhawb kev siv tau thiab kev ua raws cai
Kev xa tawm:Optimize ntau lawm throughput
Rau ntau lub chaw tsim khoom siv kho mob, EO kev tswj cov khoom seem yog suav tias yog qhov tseem ceeb raws li lub voj voog kom tsis muaj menyuam nws tus kheej.
Tej yam cuam tshuam rau EO Residual Levels
Ntau qhov hloov pauv cuam tshuam ntau npaum li cas EO tseem nyob hauv cov khoom tom qab ua kom tsis muaj menyuam.
Khoom siv:Polymeric cov ntaub ntawv xws li PVC, polyurethane, thiab cov qauv ua npuas ncauj yuav nqus tau EO roj ntau dua li cov hlau lossis iav.
Khoom Geometry:Cov khoom lag luam nrog cov lumens ntev, cov kab nqaim, lossis cov txheej txheem sab hauv feem ntau xav tau lub sij hawm aeration ntev dua.
Ntim Design:Multilayer ntim tshuab tuaj yeem ua rau qeeb qhov sib txawv ntawm EO seem thaum lub sij hawm aeration.
Sterilization Parameters:EO concentration, kub, av noo, qib nqus, thiab lub sij hawm raug cuam tshuam tag nrho rau EO nqus thiab desorption cwj pwm.
EO Aeration thiab Residual Reduction Methods
Thawj txoj kev siv los txo EO residuals yog tswj aeration.
Hom aeration systems muaj xws li:
- Chamber aeration
- Independent aeration chav
- Forced kub- cua tshuab
- Negative pressure ventilation systems
Qhov tseem ceeb aeration parameter muaj xws li:
- Kub: 35-60 ° C
- Huab cua ncig tus nqi
- Qhov cua efficiency
- Aeration duration
Nyob ntawm cov khoom siv thiab cov qauv ntim, lub sij hawm aeration yuav nyob ntawm ob peb teev mus rau ob peb hnub.
EO Residual Compliance Requirements
Cov cuab yeej siv kho mob feem ntau ntsuas EO cov seem seem raws li ISO10993-7 cov cai. Kev ntsuas yuav suav nrog kev ntsuas ntawm:
Kev ntsuam xyuas cov seem feem ntau yog muab tso rau hauv cov txheej txheem validation cov kev pab cuam los xyuas kom meej tias cov khoom sterilized raws li cov kev xav tau kev nyab xeeb ua ntej kev ua lag luam tso tawm.
Yuav Ua Li Cas Riches Txhawb EO Residual Control Projects
Riches tsim EO sterilization tshuab nrog kev koom ua ke ntawm kev tswj xyuas qhov seem. Cov kev daws teeb meem engineering tuaj yeem suav nrog cov chav ua kom muaj huab cua ywj pheej, kev ua kom zoo ntawm huab cua, EO cov pa tawm kev kho mob, qhov kub thiab txias -tswj aeration ib puag ncig, thiab PLC- raws li cov txheej txheem saib xyuas.
Rau cov tuam txhab ua cov catheters, cov khoom siv kho mob pov tseg, cov ntim cog cog, thiab lwm yam EO- cov cuab yeej siv tau yooj yim, Riches muab cov txheej txheem ua kom tsis muaj menyuam raws li cov yam ntxwv ntawm cov khoom lag luam, ntim ntau lawm, thiab cov khoom siv hauv tsev.
Los ntawm kev sib txuas cov txheej txheem kev ua kom tsis muaj menyuam, kev tsim lub tshuab aeration, thiab kev sib koom ua ke ntawm kev kho cua sov, Riches pab cov neeg siv khoom txhim kho EO seem tswj kev ua tau zoo thaum txhawb kev siv tau thiab kev tswj hwm lub hom phiaj.
