Lub Centrifuge cais cov ntshav li cas?
Kev Taw Qhia:
Kev sib cais ntshav yog ib qho txheej txheem tseem ceeb hauv ntau yam kev kho mob thiab kev tshawb fawb. Ib qho ntawm cov cuab yeej siv feem ntau rau lub hom phiaj no yog lub centrifuge. Hauv tsab xov xwm no, peb yuav tshawb nrhiav seb lub centrifuge sib cais ntshav li cas thiab nws qhov tseem ceeb hauv ntau yam kev siv xws li kev kuaj mob, kev khaws ntshav, thiab kev tshawb fawb txog kev kho mob. Peb yuav kawm txog lub tshuab tom qab kev sib cais ntshav siv lub centrifuge thiab tham txog ntau hom centrifuges siv hauv daim teb no. Yog li, cia peb kawm txog lub ntiaj teb ntawm centrifugation thiab nws lub luag haujlwm hauv kev sib cais cov khoom ntshav.
Kev Nkag Siab Txog Cov Cheebtsam ntawm Cov Ntshav
Ua ntej peb tham txog seb lub tshuab centrifuges cais cov ntshav li cas, nws yog ib qho tseem ceeb kom nkag siab txog cov khoom xyaw ntawm cov ntshav. Cov ntshav feem ntau muaj cov qe ntshav liab (erythrocytes), cov qe ntshav dawb (leukocytes), platelets (thrombocytes), thiab plasma. Txhua yam khoom ua haujlwm sib txawv hauv lub cev. Plasma nqa cov as-ham, cov tshuaj hormones, cov khoom pov tseg, thiab cov tshuaj tiv thaiv kab mob, thaum cov qe ntshav liab thiab dawb pab txhawb kev thauj cov pa oxygen thiab kev tiv thaiv kab mob.
Lub Luag Haujlwm ntawm Centrifugation hauv Kev Sib Cais Ntshav
Kev siv lub zog centrifugal los cais cov khoom me me uas muaj nyob hauv cov kua raws li lawv qhov ceev. Hauv kev sib cais cov ntshav, lub centrifuge siv los cais cov khoom uas tau hais ua ntej. Los ntawm kev tig cov ntshav mus rau qhov ceev ceev, lub centrifuge tsim lub zog centrifugal muaj zog uas thawb cov khoom me me, xws li cov qe ntshav liab, mus rau hauv qab, tsim cov pellet, thaum cov khoom me me, xws li plasma, tseem nyob rau sab saum toj.
Cov Hom Centrifuges Siv Hauv Kev Sib Cais Ntshav
Muaj ntau hom centrifuges siv rau kev sib cais ntshav, suav nrog cov centrifuges uas siv rau saum rooj thiab cov centrifuges uas siv rau hauv lub tub yees. Cov centrifuges uas siv rau saum rooj feem ntau siv rau hauv cov chaw kuaj mob rau kev kuaj ntshav ib txwm muaj, thaum cov centrifuges uas siv rau hauv lub tub yees siv los tswj qhov kub thiab txias thaum lub sijhawm sib cais, ua kom cov khoom uas rhiab heev rau cua sov ruaj khov. Ob hom no ua haujlwm raws li cov hauv paus ntsiab lus zoo sib xws, siv kev txav mus los ceev ceev los tsim lub zog centrifugal uas xav tau.
Cov Txheej Txheem Centrifugation
Cov txheej txheem ntawm kev cais cov ntshav siv lub centrifuge muaj ntau kauj ruam. Ua ntej, cov qauv ntshav raug sau thiab xa mus rau hauv ib lub raj tsim nyog, xws li lub raj centrifuge conical, uas tuaj yeem tiv taus qhov kev sib hloov ceev ceev uas xav tau. Nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo tuav cov qauv kom ntseeg tau tias muaj qhov tseeb thiab ntseeg tau. Thaum cov qauv raug khi rau hauv lub raj, nws raug muab tso rau hauv lub centrifuge, thiab lub hau raug kaw kom ruaj ntseg.
Hauv kauj ruam tom ntej, lub centrifuge raug programmed nrog cov chaw teeb tsa tshwj xeeb xws li lub sijhawm, qhov ceev, thiab kev nrawm. Cov chaw teeb tsa no raug txiav txim siab raws li qhov tshwm sim xav tau thiab cov khoom sib cais. Thaum lub rotor pib tig, lub centrifuge tsim lub zog centrifugal xav tau, ua rau cov khoom sib cais hauv cov ntshav, xws li cov qe ntshav liab, sib cais ntawm cov khoom sib cais tsawg dua. Tom qab lub sijhawm teem tseg, lub centrifuge nres.
Kev Sau thiab Kev Tshawb Fawb Txog Cov Cheebtsam Sib Cais
Tom qab lub centrifuge ua tiav nws txoj kev tig, cov khoom sib cais tuaj yeem sau thiab tshuaj xyuas ntxiv. Nyob ntawm seb qhov kev siv xav tau, cov khoom sib cais tuaj yeem hloov mus rau hauv cov raj sib txawv lossis cov thawv rau kev ua tiav ntxiv. Piv txwv li, yog tias lub hom phiaj tseem ceeb yog kom tau txais plasma, nws tuaj yeem ua tib zoo cais los ntawm lwm cov khoom siv siv lub pipette lossis lwm yam cuab yeej tsim nyog. Ib yam li ntawd, yog tias xav tau cov khoom tshwj xeeb xws li buffy coat (ua los ntawm cov qe ntshav dawb thiab platelets), lawv tuaj yeem rho tawm thiab ua tiav raws li qhov tsim nyog.
Xaus lus:
Kev siv lub tshuab centrifugation yog ib txoj kev tseem ceeb rau kev sib cais cov ntshav, uas tso cai rau cov kws tshawb fawb thiab cov kws kho mob kom tau txais cov ntshav ntshiab rau ntau yam kev siv. Los ntawm kev siv cov ntsiab cai ntawm lub zog centrifugal, cov txheej txheem no ua rau muaj kev sib cais thiab sau cov khoom sib txawv, xws li plasma, cov qe ntshav liab, thiab cov qe ntshav dawb. Lub peev xwm los sib cais cov ntshav kom zoo los ntawm lub tshuab centrifuge tau ua rau muaj kev kuaj mob, kev tshawb fawb, thiab cov txheej txheem kho mob zoo heev, txhim kho kev saib xyuas tus neeg mob thiab pab txhawb rau kev nce qib ntawm kev tshawb fawb hauv kev kho mob.
