Lub Centrifuge: Cais Cov Clot ntawm Cov Mix
Kev Taw Qhia Txog Centrifugation thiab Kev Ntshav Clotting
Kev siv centrifugation yog ib txoj kev siv tseem ceeb hauv ntau yam kev tshawb fawb thiab kev kho mob los cais cov khoom sib xyaw raws li lawv qhov ceev. Ib qho ntawm cov chaw tseem ceeb uas kev siv centrifugation ua lub luag haujlwm tseem ceeb yog hauv kev kho mob, tshwj xeeb tshaj yog kev txhaws ntshav. Tsab xov xwm no piav qhia txog qhov tseem ceeb thiab cov txheej txheem ntawm lub centrifuge hauv kev cais cov ntshav txhaws ntawm cov khoom sib xyaw.
To taub txog kev txhaws ntshav
Kev txhaws ntshav, lossis kev txhaws ntshav, yog ib qho txheej txheem nyuaj uas tiv thaiv kev los ntshav ntau dhau thaum cov hlab ntsha raug puas tsuaj. Nws muaj ntau cov kauj ruam sib law liag uas cov platelets, cov hlwb tshwj xeeb hauv peb cov hlab ntsha, tsim ib lub qhov ntawm qhov chaw raug mob thiab ua rau cov protein txhaws. Txawm li cas los xij, hauv qee yam mob, kev txhaws ntshav ntau dhau tuaj yeem tshwm sim thiab ua rau muaj kev cuam tshuam loj rau kev noj qab haus huv. Hauv cov xwm txheej zoo li no, kev cais cov ntshav txhaws ntawm cov ntshav yuav tsum tau ua.
Lub Ntsiab Cai ntawm Centrifugation
Kev siv lub tshuab centrifugation siv lub hauv paus ntsiab lus ntawm kev sib cais cov khoom sib xyaw raws li lawv qhov ceev los ntawm kev siv kev tig ceev ceev. Lub tshuab centrifuge yog lub tshuab uas ua tiav cov txheej txheem no los ntawm kev tig cov qauv ntawm qhov ceev ceev, tsim lub zog centrifugal uas cais cov khoom raws li lawv qhov hnyav. Hauv cov ntsiab lus ntawm kev txhaws ntshav, lub tshuab centrifuge tuaj yeem pab cais cov ntshav txhaws ntawm cov qe ntshav tsis txhaws thiab cov ntshav plasma.
Cov ntawv thov hauv kev kho mob thiab kev tshawb fawb
Lub luag haujlwm ntawm lub centrifuge hauv kev kho mob nthuav dav tshaj qhov tsuas yog kev sib cais cov ntshav txhaws ntawm cov khoom sib xyaw. Cov kws kho mob vam khom cov txheej txheem no rau ntau lub hom phiaj, suav nrog kev kuaj mob thiab saib xyuas cov kab mob. Cov centrifuges siv dav hauv cov chaw soj nstuam los sib cais cov khoom ntawm cov ntshav, xws li cov qe ntshav liab thiab cov qe ntshav dawb, plasma, thiab platelets. Tsis tas li ntawd, cov kws tshawb fawb vam khom cov txheej txheem sib cais los kawm txog cov yam ntxwv ntawm cov khoom tshwj xeeb kom ntxaws ntxiv.
Hom Centrifuges
Cov centrifuges muaj ntau hom thiab qhov loj me, txhua tus tsim los rau kev siv tshwj xeeb. Cov centrifuge uas siv ntau suav nrog tabletop centrifuges, microcentrifuges, thiab ultracentrifuges. Tabletop centrifuges me dua thiab haum rau cov haujlwm niaj hnub, thaum microcentrifuges yog cov chav me me siv rau kev ua cov qauv me dua. Ultracentrifuges, ntawm qhov tod tes, loj dua thiab tuaj yeem tig cov qauv ntawm qhov ceev dua, ua rau kev sib cais ntawm cov ntim loj dua thiab cov khoom me me zoo.
Cov Txheej Txheem Centrifugation rau Kev Sib Cais Clot
Yuav kom cais cov ntshav txhaws tawm ntawm cov khoom sib xyaw, lub centrifuge siv ob kauj ruam: centrifugation thiab decantation. Ua ntej, cov qauv uas muaj cov ntshav txhaws thiab cov khoom nyob ib puag ncig raug muab tso rau hauv lub raj centrifuge, uas tom qab ntawd raug muab tso rau hauv lub centrifuge. Thaum qhib, lub centrifuge pib tig sai sai, tsim lub zog uas thawb cov khoom ntom ntom dua, xws li cov ntshav txhaws, mus rau hauv qab ntawm lub raj. Cov khoom kua nyob ib puag ncig nce mus rau saum.
Kev Tshem Tawm thiab Kev Sau Cov Cheebtsam Sib Cais
Tom qab centrifugation, kauj ruam tom ntej yog decantation, qhov twg cov supernatant (cov kua saum toj ntawm cov ntshav txhaws) raug nchuav tawm lossis tshem tawm siv lub pipette. Cov txheej txheem no tso cov ntshav txhaws uas tau sib cais rau hauv qab ntawm lub raj. Cov ntshav txhaws tuaj yeem raug sau thiab tshuaj xyuas ntxiv, yog tias xav tau. Los ntawm kev sib cais cov ntshav txhaws ntawm cov khoom sib xyaw, cov kws tshawb fawb thiab cov kws kho mob tuaj yeem tau txais kev nkag siab zoo txog cov khoom sib xyaw ntawm cov ntshav txhaws, cov qauv, thiab cov teeb meem tsis zoo uas muaj.
Kev nce qib hauv kev siv tshuab centrifugation
Tau ntau xyoo los lawm, kev nce qib hauv kev siv tshuab centrifugation tau ua rau muaj kev ua haujlwm zoo dua thiab raug dua. Cov tshuab centrifuges niaj hnub no muaj cov chaw teeb tsa programmable, uas tso cai rau cov kws tshawb fawb kho qhov ceev, lub sijhawm, thiab qhov kub kom haum rau cov kev xav tau tshwj xeeb. Tsis tas li ntawd, cov yam ntxwv kev nyab xeeb siab heev txo qhov kev pheej hmoo ntawm kev ua qias tuaj ntawm cov qauv thiab kev puas tsuaj ntawm cov khoom siv. Cov kev txhim kho no tau pab txhawb rau kev nce qib hauv kev tshawb fawb kho mob thiab kev kuaj mob hauv tsev kho mob.
Xaus lus
Xaus lus, lub centrifuge ua lub luag haujlwm tseem ceeb hauv kev cais cov ntshav txhaws ntawm cov khoom sib xyaw hauv kev kho mob thiab kev tshawb fawb. Los ntawm kev siv cov ntsiab cai ntawm centrifugation, cov thev naus laus zis no ua rau muaj kev sau cov qauv huv rau kev tshuaj xyuas ntxiv. Nrog rau kev nce qib tas mus li, cov txheej txheem centrifugation txuas ntxiv mus, pab txhawb kev nkag siab thiab kev kho mob ntawm ntau yam kab mob ntshav txhaws thiab txhim kho cov txiaj ntsig kev kho mob thoob ntiaj teb.
