Cov txheej txheem kev ua haujlwm thiab kev ua pov thawj zoo ntawm Ethylene Oxide Sterilization Txee

1. Taw qhia

Ethylene oxide (EO) sterilization txee yog dav siv nyob rau hauv kev kho mob, tshuaj, thiab kev lag luam sectors rau sterilizing tshav kub- thiab ya raws - cov khoom rhiab heev. Vim tias muaj kev phom sij thiab kev tswj hwm zoo ntawm EO roj, ob qho tib si cov txheej txheem kev ua haujlwm thiab kev ua pov thawj zoo ua lub luag haujlwm tseem ceeb hauv kev ua kom tsis muaj menyuam muaj txiaj ntsig, tus neeg ua haujlwm kev nyab xeeb, thiab kev ua raws cai. Cov ntaub ntawv no qhia txog cov txheej txheem EO kom tsis muaj menyuam thiab cov txheej txheem kev txheeb xyuas qhov zoo.

 

2. Txheej txheem cej luam ntawm Ethylene Oxide Sterilization

Ethylene oxide sterilization yog ib qho qis -kub roj sterilization txoj kev uas rhuav tshem cov kab mob los ntawm kev cuam tshuam lawv cov DNA thiab cov qauv protein. EO yog qhov tshwj xeeb tshaj yog rau cov khoom siv nyuaj, cov khoom ntxeem tau, thiab ua ntej - cov khoom ntim uas tsis tuaj yeem tiv taus qhov cub lossis hluav taws xob kom tsis muaj menyuam.

 

3. Cov txheej txheem ua haujlwm ntawm Ethylene Oxide Sterilization Txee
3.1 Ua ntej-cua txias

Ua ntej ua kom tsis muaj menyuam, cov khoom raug muab tso rau hauv qhov kev tswj hwm ua ntej - qhov chaw txias qhov chaw uas qhov kub thiab txias ntawm cov av noo nyob ruaj khov. Cov kauj ruam no ua kom cov khoom ncav cuag qhov zoo ntawm cov dej noo, uas yog qhov tseem ceeb rau kev nkag mus rau EO thiab microbial inactivation.

 

3.2 Kev khiav tawm thaum pib thiab tshem tawm huab cua

Thaum thauj khoom mus rau hauv chav ua kom tsis muaj menyuam, huab cua raug tshem tawm los ntawm kev tshem tawm lub tshuab nqus tsev lossis tso dej nitrogen. Tshem tawm cov pa oxygen txo qhov kev pheej hmoo tawg thiab tso cai rau kev faib tawm ntawm EO roj thoob plaws hauv lub chamber.

 

3.3 Humidification

Moisture yog reintroduced rau hauv lub chamber los ntawm kev tswj chav txhaj tshuaj. Cov av noo zoo txhim kho EO txoj kev ua kom tsis muaj menyuam los ntawm kev txhim kho microbial susceptibility thiab gas diffusion.

 

3.4 Ethylene Oxide Gas Txhaj thiab raug

EO roj yog vaporized thiab txhaj rau hauv lub chamber ntawm qhov kev tswj hwm qhov tseeb. Thaum lub sij hawm raug, qhov kub thiab txias, av noo, roj concentration, thiab lub sij hawm raug tswj nyob rau hauv validated txwv kom ua tau raws li qhov yuav tsum tau Sterility Assurance Level (SAL).

 

3.5 Tshaj tawm -Kev tshem tawm cov pa tawm

Tom qab ua kom tsis muaj menyuam, EO roj raug tshem tawm los ntawm kev rov ua dua lub tshuab nqus tsev thiab lub voj voog tshem tawm nitrogen. Cov kauj ruam no txo ​​cov chamber EO concentration kom muaj kev nyab xeeb, tsis yog - qib flammable thiab pib cov txheej txheem desorption los ntawm cov khoom tsis huv.

3.6 Heated Aeration

Cov khoom ua kom tsis muaj menyuam raug xa mus rau qhov chaw cua sov uas muaj EO seem thiab los ntawm - cov khoom raug tso tawm dhau sijhawm. Kev tsim nyog aeration ua kom cov khoom ua tau raws li kev tswj hwm kev txwv tsis pub ua ntej tso tawm.

 

4. Kev Tshawb Fawb Zoo thiab Kev Ua Haujlwm Zoo
4.1 Sterilization txheej txheem validation

EO sterilization txee yuav tsum ua raws li ISO 11135, uas txhais cov kev cai rau kev txhim kho txheej txheem, kev tsim nyog tsim nyog (IQ), kev tsim nyog ua haujlwm (OQ), thiab kev tsim nyog (PQ). Validation qhia tau hais tias txoj kev ua kom tsis muaj menyuam tsis tu ncua ua tiav qhov xav tau SAL ntawm 10⁻⁶.

 

4.2 Kev soj ntsuam thiab kev tswj xyuas niaj hnub

Cov txheej txheem tseem ceeb -xws li qhov kub thiab txias, av noo, EO concentration, siab, thiab lub sij hawm raug- tau soj ntsuam thiab kaw tsis tu ncua. Cov ntsuas tshuaj lom neeg, cov ntsuas tshuaj lom neeg, thiab cov ntaub ntawv thauj khoom yog siv los txheeb xyuas cov txheej txheem tsis tu ncua.

 

4.3 Residual Gas Control thiab Safety Assurance

Cov qib EO seem yuav tsum ua raws li ISO 10993-7 txwv. Cov khoom ua kom tsis muaj menyuam yog tsim los nrog cov chav kaw, cov tshuab kuaj pom cov pa, thiab cov chav kho cua kom ua kom cov neeg ua haujlwm muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig. Kev tswj hwm kev pheej hmoo yog ua raws li ISO 14971.

 

5. Cov lus xaus

Ethylene oxide sterilization txee tso siab rau kev ua tib zoo tswj, ntau- cov txheej txheem kom xa cov kev ua kom tsis muaj menyuam rau cov khoom rhiab heev. Los ntawm cov txheej txheem kev ua haujlwm tau zoo thiab kev kuaj xyuas zoo, EO sterilization systems ua kom tsis muaj menyuam zoo ib yam thaum ua tau raws li kev nyab xeeb thoob ntiaj teb thiab kev tswj hwm. Kev siv tau zoo, kev saib xyuas, thiab kev tswj cov khoom seem yog qhov tseem ceeb rau kev tswj xyuas cov khoom zoo thiab cov neeg siv kev nyab xeeb.
