Centrifuges rau Nucleic Acid Test ntawm Coronavirus COVID-19

Raws li kev kis mob ntsws uas tshwm sim los ntawm tus kabmob coronavirus COVID-19 tau kis mus thoob plaws tebchaws, ntau thiab ntau tus neeg pib txhawj xeeb tias tus kabmob kis yuav hloov mus rau kev sib kis. Cov kws tshawb fawb thiab kws kho mob tau ua haujlwm ua ke thoob ntiaj teb los kawm ntxiv txog tus kabmob tshiab no thiab sim tsim cov tshuaj tiv thaiv sai li sai tau.

Rau kev kuaj mob hauv chaw kuaj mob, centrifuge yog ib qho ntawm cov cuab yeej tseem ceeb hauv chav kuaj nucleic acid kuaj tus mob coronavirus COVID-19. Raws li cov chaw tsim khoom thiab kev lag luam ntawm lab centrifuge, peb muaj lub luag haujlwm los muab peb lub zog los tawm tsam tus kabmob no. Tam sim no peb muaj 3 tus qauv tsim nyog rau lub chaw kuaj mob thiab kuaj mob.

Rotor:
Lub kaum sab xis Rotor 24x1.5ml, 16000rpm, 23800xg
Nrog aerosol-tight hau

Rotor:
Swing Rotor 48x5ml, 4000rpm, 2980xg
suav nrog ib (stainless nyiag) rotor caj npab thiab 4 (txhuas hlau) cov thoob
Rau cov hlab ntim ntshav (vacutainers) 5ml (13x100mm)
Nrog aerosol-tight hau

Swing Rotor 48x2ml, 4000rpm, 2625xg
suav nrog ib (stainless nyiag) rotor caj npab thiab 4 (txhuas hlau) cov thoob
Rau cov hlab ntim ntshav (vacutainers) 2ml (13x75mm)
Nrog aerosol-tight hau

Cov qauv saum toj no 3 thiab rotors xav tau ntau dua li ntau zaus vim qhov xav tau ntau ntxiv los ntawm kev kuaj mob ntawm tus mob coronavirus COVID-19. Xiangzhi lub tuam txhab tab tom sim qhov zoo tshaj plaws los xyuas kom meej cov khoom tsim thiab muab rau cov qauv no. Thiab ntawm daim ntawv xaj peb xav txog biosafety ua ntej rau cov neeg ua haujlwm hauv chaw kuaj mob, peb txaus siab rau cov lus qhia thiab cov lus pom zoo ntawm kev txhim kho peb cov qauv centrifuge uas tuaj yeem tiv thaiv cov neeg ua haujlwm hauv chaw kuaj mob zoo dua.

Thaum kawg, thov nco ntsoov cov ntsiab lus hauv qab no thaum tuav cov khoom siv phom sij txaus ntshai hauv chav kuaj:
Ua haujlwm hauv cov chaw kuaj mob kuaj mob feem ntau txhais tau tias ua haujlwm nrog cov qauv uas muaj feem kis tau zoo li ntshav lossis lwm yam kua hauv lub cev. Tab sis tuav cov kab mob sib kis los yog cov tshuaj tsis zoo yog qhov muaj nyob hauv cov chaw tshawb fawb thiab. Txhawm rau kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm hauv chaw kuaj mob thiab tiv thaiv kev kuaj mob kis tau tus kab mob (LAIs) lossis lwm yam kev phom sij rau kev noj qab haus huv, kev ceev faj tsim nyog yuav tsum tau ua nyob rau hauv tag nrho cov haujlwm ua haujlwm.

Centrifuge yog ib qhov chaw ntawm aerosols. Muaj ntau yam kev ua ub no - suav nrog kev sau cov raj centrifuge, tshem lub kaus mom lossis lub hau los ntawm cov raj tom qab centrifugation, thiab tshem tawm cov kua supernatant thiab tom qab ntawd rov ua cov pellets - tuaj yeem ua rau tso cov aerosols mus rau hauv chav kuaj ib puag ncig.
Yog li, aerosol-tight hau los yog biocontainment cover yog qhov tseem ceeb rau centrifuging cov qauv phom sij, xws li cov hlab ntim ntshav (vacutainers)

Aerosol-tight hau tsis tiv thaiv kev tsim ntawm aerosols thaum centrifugation; es, lawv xyuas kom meej tias aerosols tsis tuaj yeem los ntawm qhov kaw kaw.
Yog tias lub raj tawg lossis xau, tsis txhob qhib lub centrifuge tsawg kawg 30 feeb tom qab khiav. Txij li qhov no tsis tuaj yeem kuaj pom txhua lub sijhawm ua ntej koj qhib lub thoob lossis rotor (qhov tsis txaus siab tam sim ntawd tuaj yeem yog thawj lub cim ntawm lub raj tawg), peb xav kom tos tsawg kawg 10 feeb txhua lub sijhawm ua ntej koj qhib lub ntim.
Tsis tas li, koj yuav tsum thauj khoom thiab tshem tawm cov thoob lossis rotor hauv lub txee biosafety (tshwj xeeb tshaj yog nyob rau hauv kab mob thiab cov kab mob mycobacteriology) kom txo qis kev pheej hmoo ntawm kev khiav tawm aerosols.
