Microorganisms:
●Ma BI ali ndi spores za mabakiteriya osamva kwambiri, makamaka Bacillus atrophaeus kapena Geobacillus stearothermophilus.
●Ma spores awa amasankhidwa chifukwa chodziwika kuti amakana ethylene oxide, kuwapangitsa kukhala abwino kutsimikizira njira yotseketsa.
Wonyamula:
●Ma spores amagwiritsidwa ntchito kuzinthu zonyamulira monga pepala, chitsulo chosapanga dzimbiri, kapena pulasitiki.
●Chonyamuliracho chimatsekedwa mu phukusi lotetezera lomwe limalola mpweya wa EtO kulowa mkati ndikusunga umphumphu wa spores.
Kupaka koyambirira:
●Ma BI amatsekeredwa muzinthu zomwe zimawonetsetsa kuti zitha kugwidwa mosavuta ndikuyikidwa mkati mwa katundu woletsa.
●Zopakazo zidapangidwa kuti zizitha kulowa mu gasi wa ethylene oxide koma osasunthika ndi zowononga zachilengedwe.
Kuyika:
●Ma BI amayikidwa m'malo omwe ali mkati mwa chipinda chotsekereza momwe mpweya uyenera kukhala wovuta kwambiri, monga pakati pa mapaketi owundana kapena zida zamkati.
●Zizindikiro zambiri zimagwiritsidwa ntchito m'malo osiyanasiyana kuti zitsimikizire kugawidwa kwa gasi kofanana.
Njira yotsekera:
●Chowumitsa chimayendetsedwa mozungulira mozungulira, nthawi zambiri kumaphatikizapo mpweya wa EtO pamlingo wina wake, kutentha, ndi chinyezi kwanthawi yodziwikiratu.
●Ma BI amakumana ndi mikhalidwe yofanana ndi zinthu zomwe zimaseweredwa.
Makulitsidwe:
●Pambuyo pa njira yotseketsa, ma BI amachotsedwa ndikuyikidwa pansi pamikhalidwe yabwino pakukula kwa zamoyo zoyesa (mwachitsanzo, 37°C pa Bacillus atrophaeus).
●Nthawi yamakulitsidwe nthawi zambiri imakhala pakati pa maola 24 mpaka 48.
Kuwerenga Zotsatira:
●Akamakulitsidwa, ma BI amawunikidwa kuti awonetse zizindikiro za kukula kwa tizilombo. Palibe kukula komwe kumasonyeza kuti njira yobereketsa inali yothandiza kupha spores, pamene kukula kumasonyeza kulephera.
●Zotsatira zimatha kuwonetsedwa ndi kusintha kwa mtundu mu kukula kwa sing'anga kapena turbidity.
Kutsimikizira ndi Kuyang'anira:
●Ma BI amapereka njira yodalirika komanso yachindunji yotsimikizira kugwira ntchito kwa njira zotsekera za EtO.
●Amathandizira kuwonetsetsa kuti magawo onse a katundu wosabala afika pamikhalidwe yofunikira kuti akwaniritse sterility.
Kutsata Malamulo:
●Kugwiritsa ntchito ma BI nthawi zambiri kumafunika ndi malamulo ndi malangizo (monga ISO 11135, ANSI/AAMI ST41) kuti atsimikizire ndikuwunika njira zoletsa.
●Ma BI ndi gawo lofunikira kwambiri pamapulogalamu otsimikizira zaumoyo ndi mafakitale, kuonetsetsa chitetezo cha odwala komanso ogula.
Chitsimikizo chadongosolo:
●Kugwiritsa ntchito pafupipafupi ma BI kumathandizira kukhalabe ndi miyezo yapamwamba yoletsa matenda popereka chitsimikiziro chokhazikika cha magwiridwe antchito a sterilizer.
●Ndi gawo la pulogalamu yowunikira njira yoletsa kubereka yomwe ingaphatikizepo zizindikiro za mankhwala ndi zida zowunikira.
Zizindikiritso Zachilengedwe Zokhazikika (SCBIs):
●Izi zikuphatikizapo spore carrier, kukula kwapakati, ndi incubation system mu unit imodzi.
●Pambuyo poyang'anizana ndi njira yolera yotseketsa, SCBI ikhoza kutsegulidwa ndi kulowetsedwa mwachindunji popanda kugwiriridwa kwina.
Zizindikiro Zachilengedwe Zachilengedwe:
●Izi nthawi zambiri zimakhala ndi spore strip mkati mwa envulopu yagalasi kapena vial.
●Izi zimafunikira kusamutsidwa kupita kumalo okulirapo pambuyo pa kutseketsa kwa ma incubation ndi kutanthauzira zotsatira.
Kutengeka Kwambiri:
●Ma BI amazindikira kukhalapo kwa spores za bakiteriya zolimbana kwambiri, zomwe zimapatsa mayeso okhwima a njira yotseketsa.
Kutsimikizira kwathunthu:
●Ma BI amatsimikizira njira yonse yoletsa kutsekereza, kuphatikiza kulowa kwa mpweya, nthawi yowonekera, kutentha, ndi chinyezi.
Chitsimikizo cha Chitetezo:
●Amawonetsetsa kuti mankhwala osabala ndi otetezeka kuti agwiritsidwe ntchito, opanda tizilombo toyambitsa matenda.
