Sterility yog hais txog qhov tshwm sim ntawm kev muaj sia nyob ntawm ib qho kab mob tom qab ua kom tsis muaj menyuam, tseem hu ua sterility assurance level (SAL), feem ntau hais tias yog 10-n. Tam sim no, qhov kev pom zoo yog tias SAL10-6 tsis muaj menyuam.
Cov kev ua kom tsis muaj menyuam muaj xws li: kev kub siab ua kom tsis muaj menyuam, hydrogen peroxide plasma sterilization, ethylene oxide sterilization, ionizing hluav taws xob sterilization, thiab ziab tshav kub kom tsis muaj menyuam.
Kev sib piv ntawm txoj kev ua kom tsis muaj menyuam, cov qauv, kev siv, qhov zoo thiab qhov tsis zoo
1. Kev kub siab Steam Sterilization
Lub hauv paus ntsiab lus: tua cov kab mob feem ntau los ntawm irreversibly coagulating thiab denaturing enzymes thiab proteins nyob rau hauv cov kab mob.
Daim ntawv thov: Feem ntau yog siv los kho dej, tshuaj, tswj kev kho mob pov tseg thiab cov khoom tsis ntxeem tau uas nws qhov chaw raug ncaj qha rau chav. Rau perforated loads thiab cov twj paj nruag, qhov ntsuas kub thiab lub sij hawm ua kom tsis muaj menyuam yog 132-135 degree rau 3-4 feeb. Feem ntau siv sterilization kub yog 121 degree thiab 132 degree.
Qhov zoo: tsis muaj tshuaj lom thiab ib puag ncig tus phooj ywg, cov txheej txheem yooj yim los tswj thiab saib xyuas, kev ua kom tsis muaj menyuam sai thiab ua haujlwm tau zoo, cov txheej txheem kom tsis muaj menyuam muaj kev cuam tshuam tsawg heev los ntawm cov organic lossis inorganic paug, lub sijhawm ua kom tsis muaj menyuam yog luv, thiab nws tuaj yeem nkag mus tau zoo. instrument pob thiab lumen-type instruments.
Qhov tsis zoo: kev puas tsuaj rau cov khoom siv hluav taws xob kub, qhov rov ua kom tsis muaj menyuam yuav ua rau cov cuab yeej phais mob puas tsuaj, thiab tuaj yeem ua rau cov cuab yeej xeb vim cov pob ntub dej, muaj peev xwm scalding.
2. Hydrogen Peroxide Plasma Sterilization
Lub hauv paus ntsiab lus: Hydrogen peroxide plasma muaj cov haujlwm oxidative siab thiab tua cov kab mob los ntawm kev rhuav tshem cov cellular proteins, enzymes thiab nucleic acids.
Daim Ntawv Thov: Siv rau kev ua kom tsis muaj menyuam ntawm cov khoom siv kho mob uas tsis ruaj khov rau cov cua sov thiab noo noo.
Qhov zoo: kev nyab xeeb thiab ib puag ncig tus phooj ywg, tsis muaj tshuaj lom, lub voj voog ua kom tsis muaj menyuam ntawm 28-75 feeb, tsis xav tau kev tshuaj xyuas, haum rau kev ua kom tsis muaj cua sov thiab noo noo rhiab cov khoom, yooj yim rau kev khiav lag luam, nruab thiab saib xyuas, thiab sib xws nrog cov twj paj nruag feem ntau.
Disadvantages: Tsis haum rau cov ntawv fibers, paj rwb thiab linen, cov khoom ua kua, qhov luaj li cas ntawm cov kab noj hniav me me (50 ~ 270 L), tsis haum rau endoscopy los yog cov cuab yeej nrog slender lumen, yuav tsum tau siv cov khoom ntim khoom (xws li polypropylene ntim. los yog polyolefin tube hnab, thiab lwm yam), hydrogen peroxide tej zaum yuav muaj kuab lom nyob rau hauv koob ntau tshaj 1 ppm.
3. Ethylene Oxide Sterilization
Lub hauv paus ntsiab lus: Ethylene oxide induces cell tuag los ntawm alkylating proteins, DNA, thiab RNA, irreversibly tiv thaiv cell metabolism thiab replication.
Daim ntawv thov: siv rau cov khoom muaj kev pheej hmoo siab uas tsis tiv taus cov dej noo thiab cua sov.
Qhov zoo: Nws tuaj yeem ua kom tsis muaj cua sov-rhiab thiab noo noo-rhiab cov khoom siv kho mob yam tsis muaj teeb meem rau nws cov ntaub ntawv, tuaj yeem nkag mus rau cov khoom ntim thiab cov khoom siv lumen zoo, lub thawv ntim ib zaug thiab lub zog tsis zoo, txo qhov kev pheej hmoo ntawm cov pa tawm, yooj yim rau kev khiav lag luam. siv thiab saib xyuas, sib xws nrog feem ntau cov twj paj nruag.
Disadvantages: tus nqi siab, muaj peev xwm tsim kev puas tsuaj rau cov neeg mob thiab cov neeg ua haujlwm kho mob. Nws yuav tsum tau soj ntsuam ntev ntev kom tshem tawm cov roj ethylene oxide residual. Lub sterilizer yog me me ({0}}L), tshuaj lom, carcinogenic thiab flammable. Lub tank yuav tsum tau muab khaws cia rau hauv lub thawv ntim khoom tawg, uas yuav tsum tau ua kom tsis muaj menyuam ntev thiab lub sijhawm tshuaj xyuas.
4. Ionizing Radiation Sterilization
Lub hauv paus ntsiab lus: Cov-ray emitted los ntawm radioisotope cobalt 60 yog siv los ua kom tsis muaj menyuam zoo. Cov-ray tuaj yeem tsim cov hlwb los tsim cov dawb radicals, rhuav tshem cov metabolism hauv ib txwm, thiab tom qab ntawd ua rau cov kab mob tsis ua haujlwm.
Daim ntawv thov: Tsawg kub kom tsis muaj menyuam siv rau ntau yam khoom siv kho mob (xws li hloov cov ntaub so ntswg, tshuaj, khoom siv kho mob).
Qhov zoo: Nws tuaj yeem nqa tawm ntawm chav tsev kub yam tsis muaj kev tshwj xeeb rau qhov kub thiab txias ib puag ncig, kev ua kom tsis muaj menyuam yog qhov sib xws thiab meej, qhov nrawm nrawm, thiab nws tuaj yeem ua haujlwm tsis tu ncua. Haum rau kev ua kom tsis muaj menyuam loj.
Qhov tsis zoo: tus nqi siab ntawm kev ua kom tsis muaj menyuam, qee cov khoom tuaj yeem hloov lawv cov khoom tom qab hluav taws xob, xyuam xim rau kev tiv thaiv kev nyab xeeb.
5. Qhuav cua sov Sterilization
Lub hauv paus ntsiab lus: Cov kab mob tuag yog tshwm sim los ntawm kev kub siab oxidation ntawm cov khoom ntawm tes.
Daim ntawv thov: Rau cov ntaub ntawv uas tsis tiv taus cua sov los yog tsis tuaj yeem nkag los ntawm cov cua sov (xws li hmoov, cov khoom siv roj av, cov khoom siv ntse). Lub sijhawm thiab qhov kub thiab txias tshaj plaws yog 170 degree thiab 60 min, 160 degree thiab 120 min, thiab 150 degree thiab 150 min.
Qhov zoo: non-toxic, environmentally friendly, qhuav cua sov txee yog ib qho yooj yim rau nruab, kuj tsis tshua muaj nqi khiav lag luam, tuaj yeem nkag mus rau cov ntaub ntawv, tsis-corrosive rau hlau thiab sharps, thiab lwm yam.
Disadvantages: Qhov ceev ntawm sterilization tshav kub nkag thiab tua microbial yog qeeb, thiab sterilization yog siv sij hawm. Qhov kub thiab txias tsis haum rau cov khoom siv feem ntau.
Ntxiv rau txoj kev ua kom tsis muaj menyuam saum toj no, kev kho mob / kws kho mob kom tsis muaj menyuam kuj tseem muaj lwm yam kev ua kom tsis muaj menyuam, xws li peracetic acid sterilization, ozone sterilization, ultraviolet irradiation sterilization, microwave sterilization, filtration sterilization, thiab lwm yam.
