3.4.1 eto sterilizer tshuab Kub Qhov Chaw Ua Haujlwm
Qhov ntsuas kub ntawm eto sterilizer yog: 30 txog 70 ° C, nrog kev tswj tsis raug ntawm ?2 ° C.
3.4.2 Temperature Uniformity ntawm lub tshuab ethylene oxide
Qhov kub tsis sib xws ntawm eto sterilizer yuav tsum ua raws li cov cai hauv qab no:
Thaum lub ntim ntawm lub sterilization chamber yog ?5m³, tsawg kawg yog 10 ntsuas cov ntsiab lus yuav tsum tau muab tso rau.
Thaum lub ntim yog >5m³, rau txhua qhov ntxiv 1m³, ib qho ntsuas ntxiv yuav tsum tau ntxiv.
Thaum lub ntim yog ?10m³, yam tsawg kawg 20 ntsuas cov ntsiab lus yuav tsum tau teem nyob rau hauv lub chamber, nrog rau qhov ntsuas kub ?40 ° C, thiab qhov kub ntawm qhov sib txawv ntawm txhua qhov ntsuas yuav tsum tsis txhob tshaj ± 3 ° C.
3.4.3 Sterilization Chamber Leakage Rate
3.4.3.1
Testing should be conducted before the injection phase of the sterilizing agent and the humidification phase (if using an inserted temperature and pressure display device). The pressure should be preset by the manufacturer, and the test pressure should be less than -20 kPa and at least 20 kPa lower than the preset sterilization pressure.
3.4.3.2
If the pressure during any stage of the sterilization cycle is below atmospheric pressure, after reaching the preset pressure, all valves connected to the sterilization chamber should be closed, and the vacuum pump should stop working. The pressure in the sterilization chamber should be monitored for at least 5 minutes, during which the pressure rise must not exceed 0.3 kPa/min.
3.4.3.3
Thaum lub siab ua hauj lwm ntawm lub eo chamber yog ntau tshaj 5 kPa, yuav tsum tau ua ib tug zoo siab leakage test, uas yuav tsum tau ua ua ntej lub nqus tsev vacuum theem. Los ntawm kev kub siab nrog cov roj inert (xws li huab cua) kom nyob rau hauv 10% ntawm lub preset ua hauj lwm siab, lub siab nyob rau hauv lub sterilization chamber yuav tsum tau saib xyuas tsawg kawg yog 5 feeb, thaum lub sij hawm lub siab poob yuav tsum tsis txhob ntau tshaj 0.3 kPa / min.
3.4.4 eto sterilizer tshuab nqus tsev vacuum
Nyob rau hauv tsis muaj-load tej yam kev mob, eo chamber yuav tsum ncav cuag -15 kPa los ntawm atmospheric siab nyob rau hauv ?6 feeb; ncav cuag -50 kPa hauv 30 feeb; thiab ncav cuag -75 kPa hauv ?40 feeb.
3.4.5 Humidification nyhuv ntawm eto sterilizer tshuab
Nyob rau hauv tsis muaj-load tej yam kev mob, thaum tus txheeb ze humidity yog ?40% RH, lub eo sterilization tshuab yuav tsum muaj peev xwm ua kom cov txheeb ze humidity tsawg kawg yog 75% los yog siab dua los ntawm lub humidification system.
3.4.6 Siab Setting Range ntawm Sterilization Chamber
Lub siab teeb tsa ntau yam rau lub sterilization chamber yog -0.08 MPa rau +0.08 MPa.
3.4.7 Qib Siab Tshaj Plaws ntawm eto sterilizer tshuab
Qhov siab tshaj plaws suab nrov (A-hnyav) ua los ntawm eto sterilization chamber yuav tsum yog ?65 dB.
3.4.8 Cov tsos mob thiab cov qauv ntawm ethylene oxide sterilizer
3.4.8.1
Cov duab yuav tsum yog upright, nrog ib tug du thiab huv si saum npoo, cov xim sib xws, thiab tsis muaj burrs, ntse npoo, thiab tawg. Yuav tsum tsis muaj qhov pom tseeb khawb lossis tsis xws li pob.
3.4.8.2
Tag nrho cov ntawv nyeem, cov duab, cov cim, thiab lwm yam, ntawm qhov chaw yuav tsum tau luam tawm kom meej, nrog rau cov cim uas meej, meej, thiab ruaj khov.
3.4.8.3
Cov fasteners yuav tsum raug ntsia kom ruaj ntseg, thiab tag nrho cov kev tswj cov keyboards thiab kev hloov kho pob qhov rooj (khawm) yuav tsum ua haujlwm yooj yim thiab ntseeg tau, tsis muaj kev cuam tshuam.
