Kev ua tiav ntawm ib qho Ethylene Oxide (ETO) sterilizer xav tau ntau tshaj li lub tshuab nws tus kheej; nws xav tau ib qho kev txhim kho zoo ntawm cov khoom siv hluav taws xob tseem ceeb, kev ruaj ntseg, thiab kev txhawb nqa tsis tu ncua. Ua kom ntseeg tau tias cov kev cai no tau ua tiav yog qhov tseem ceeb rau cov txheej txheem kev ua haujlwm, kev nyab xeeb ntawm tus neeg teb xov tooj, thiab kev tswj hwm kev tswj hwm (xws li ISO 11135).

Hauv qab no yog cov lus qhia dav dav rau cov kev pabcuam tseem ceeb thiab cov txheej txheem tsim nyog rau kev ua haujlwm siab ETO sterilization suite.

1. Core Utilities rau Sterilization Cycle

Cov khoom siv hluav taws xob no tau koom ncaj qha rau hauv cov txheej txheem tshuaj thiab lub cev ib puag ncig ntawm lub tshuab kom tsis muaj menyuam.

  • Ethylene Oxide (EO) Gas Supply: Tus thawj sterilant, feem ntau yog muab rau hauv 100% EO cartridges los yog lub tog raj kheej pressurized (piv txwv li, EO / CO? mixs).
  • Cov Cuab Yeej Cuab Yeej (Steam/Electricity): Kev tswj qhov kub thiab txias yog qhov tseem ceeb. Cov tshuab siv chav dej los yog lub tsho dej kub los tswj lub chamber nruab nrab 37 ° C thiab 55 ° C. Ntau qhov chaw xav tau a Ntshiab Steam Generator los tiv thaiv kev kis kab mob.
  • Humidification: Txij li thaum EO tsuas yog siv tau rau hauv qhov chaw ntub dej, dej / chav dej yog txhaj rau lub sijhawm ua ntej kom ncav cuag cov txheeb ze av noo (RH).
  • Lub tshuab nqus tsev: Lub tshuab nqus tsev twj tso kua mis skid yog tsim nyog los tshem tawm cov huab cua (thaum pib) thiab tshem tawm cov roj seem (tom qab lub voj voog aeration).
  • Compressed Cua: Cov huab cua huv, qhuav compressed yuav tsum tau ua kom cov pneumatic li qub thiab pab txhawb cov huab cua ntshiab thaum lub sij hawm aeration thiab purging.

2. Kev nyab xeeb thiab ib puag ncig Infrastructure

Vim hais tias Ethylene Oxide yog ob qho tib si tshuaj lom thiab kub heev, tshwj xeeb kev ruaj ntseg systems tsis yog sib tham.

Cua thiab cua tshuab

  • Dedicated Room Exhaust: Khaws cia tsis zoo siab nyob rau hauv ETO suite kom tiv thaiv kev tsiv teb tsaws ntawm cov pa mus rau qhov chaw ua haujlwm nyob ib sab.
  • Sterilizer Exhaust System: Ib txoj kab tshwj xeeb uas coj cov roj los ntawm lub chamber mus rau qhov kev tshem tawm (scrubber lossis catalytic oxidizer) kom muaj kev nyab xeeb ntawm ib puag ncig.

EO Kev Tshawb Fawb thiab Kev Tshawb Fawb

  • Gas Detection Systems: Kev saib xyuas huab cua tsis tu ncua nrog cov sensors thiab lub tswb txhawm rau txhawm rau txhawm rau txhawm rau EO hauv lub sijhawm tiag tiag, ua kom cov neeg ua haujlwm nyab xeeb.

3. Pre- thiab Post-Sterilization Logistics

Kev ua haujlwm tau zoo yuav tsum muaj qhov chaw tshwj xeeb rau:

  • Cov chav ua ntej: Qhov twg cov khoom yog stabilized ntawm qhov kub thiab av noo theem ua ntej nkag mus rau lub sterilizer.
  • Chav Aeration: Rhaub, ventilated qhov chaw siv los tawm cov roj seem EO los ntawm cov khoom tsis huv thiab ntim khoom.

4. Kev Ua Raws Cai thiab Kev Pab Txhawb

Kom tswj tau Sterility Assurance Levels (SAL) thiab cov cuab yeej siv tau ntev, cov kev pabcuam txuas ntxiv yuav tsum tau ua.

Validation Services (IQ/OQ/PQ)

Kev nruj nruj ua kom cov txheej txheem ua tau raws li cov qauv thoob ntiaj teb:

  • Installation Qualification (IQ): Xyuas kom tseeb tias cov cuab yeej raug ntsia raws li cov chaw tsim khoom thiab kev nyab xeeb specifications.
  • Kev Tsim Nyog Ua Haujlwm (OQ): Paub meej tias lub kaw lus ua haujlwm raug raws li nws cov kev txwv.
  • Kev Kawm Txuj Ci (PQ): Lub sijhawm tseem ceeb tshaj plaws, ua pov thawj cov txheej txheem tsis tu ncua ua tiav a $10^{-6}$ SAL siv cov cim qhia txog roj ntsha (BIs).

Kho thiab Calibration

  • Kev Tiv Thaiv Kev Kho Mob: Teem sijhawm hloov cov gaskets, lim dej, thiab cov twj tso kua mis los tiv thaiv kev xau thiab kev poob qis.
  • Sensor Calibration: Txhua zaus calibration ntawm qhov kub, siab, thiab av noo sensors kom paub meej lub voj voog rov ua dua.

Kev cob qhia thiab cov ntaub ntawv

  • Kev cob qhia neeg ua haujlwm: Cov kev pabcuam dav dav suav nrog kev tuav roj, teb thaum muaj xwm txheej ceev, thiab kev txhais cov ntaub ntawv lub voj voog.
  • Audit-Ready Documentation: Cov ntaub ntawv hluav taws xob lossis lub cev taug qab cov voj voog ncig, keeb kwm kev saib xyuas, thiab cov ntaub ntawv raug tus neeg ua haujlwm.
