Chophimba cha Biocontainment cha Chidebe cha Rectangular

Nthawi: 2022-01-22 Phokoso: 166

Chidebe chomakona anayi chokhala ndi mabowo 12 amapangidwa mwapadera kuti azigwira ndi 5ml(13x100mm) ndi 2ml(13x75mm) machubu osonkhanitsira magazi (mavacutainers). Ndi machubu okwana 48 nthawi imodzi, ma swing out rotor 48x5ml ndi 48x2ml amapereka ntchito yabwino kwambiri m'ma laboratories ozindikira matenda m'chipatala.

Komabe, kugwira ntchito m'ma laboratories ozindikira matenda nthawi zambiri kumatanthauza kugwira ntchito ndi zitsanzo zomwe zitha kupatsirana ngati magazi kapena madzi ena am'thupi. Koma kuthana ndi tizilombo toyambitsa matenda kapena mankhwala owopsa ndikofalanso m'ma laboratories ofufuza. Kuwonetsetsa chitetezo cha ogwira ntchito mu labotale ndikupewa matenda omwe amapezeka mu labotale (LAIs) kapena zoopsa zina zaumoyo, kusamala koyenera kuyenera kutsatiridwa munthawi yonseyi.

Centrifuge ndi gwero limodzi la aerosols. Zochita zambiri - kuphatikiza kudzaza machubu apakati, kuchotsa zipewa kapena zotsekera pamachubu pambuyo pa centrifugation, ndikuchotsa madzi ochulukirapo ndikuyimitsanso ma pellets - zitha kupangitsa kuti ma aerosol atulutsidwe kumalo a labotale.
Chifukwa chake, chivundikiro cha biocontainment ndichofunikira pakuyika zitsanzo zowopsa, monga machubu osonkhanitsira magazi (ma vacutainers)

Zophimba za biocontainment sizilepheretsa mapangidwe a aerosols panthawi ya centrifugation; m'malo mwake, amawonetsetsa kuti ma aerosols sangatuluke munjira yotsekedwa.
Ngati chubu chasweka kapena kutayikira, musatsegule centrifuge kwa mphindi 30 mutathamanga. Popeza izi sizingadziwike nthawi zonse musanatsegule zidebe kapena rotor (kusagwirizana kwadzidzidzi kungakhale chizindikiro choyamba cha kusweka kwa chubu), timalimbikitsa kuyembekezera mphindi 10 nthawi zonse musanatsegule zitsulo.
Komanso, muyenera kukweza ndi kutsitsa zidebe kapena rotor mu kabati yoteteza zachilengedwe (makamaka mu virology ndi mycobacteriology) kuti muchepetse chiopsezo chothawa ma aerosol.
Biosafety ndiyofunikira kwa ogwira ntchito ku labu, timayamikira kwambiri upangiri ndi malingaliro owongolera mapangidwe athu a centrifuge omwe amatha kuteteza ogwira ntchito ku labu bwino.
