Nws siv sijhawm ntev npaum li cas hauv centrifuge los cais cov platelets
Nkag Siab Txog Lub Ntsiab Cai ntawm Kev Sib Cais Platelet hauv Centrifugation
Kev siv centrifugation yog ib txoj kev siv dav hauv cov chaw kuaj mob thiab cov chaw kho mob los cais ntau yam khoom ntawm cov qauv kuaj mob. Ib qho tseem ceeb ntawm kev siv cov txheej txheem no yog kev sib cais cov platelets ntawm cov ntshav tag nrho. Cov platelets yog cov khoom tseem ceeb ntawm cov ntshav uas ua rau cov ntshav khov, kho qhov txhab, thiab kho cov ntaub so ntswg. Hauv tsab xov xwm no, peb yuav tshawb nrhiav cov txheej txheem ntawm kev sib cais platelet siv centrifugation thiab tshuaj xyuas cov yam ntxwv uas cuam tshuam rau lub sijhawm xav tau rau kev sib cais no.
Lub Centrifuge: Lub zog rau kev sib cais cov ntshav
Lub centrifuge yog ib qho khoom siv tseem ceeb rau kev sib cais cov ntshav platelet. Nws ua haujlwm raws li lub hauv paus ntsiab lus ntawm lub zog centrifugal, qhov twg cov qauv raug tig sai sai kom sib cais nws cov khoom raws li lawv qhov ceev. Thaum cov ntshav tag nrho raug muab tso rau hauv lub centrifuge, lub zog ntawm kev tig ua rau cov qe ntshav liab hnyav dua poob rau hauv qab, thaum cov platelets sib dua tsim ib lub "txheej buffy." Lub txheej buffy yog txheej ntawm cov qe ntshav liab uas tau poob thiab cov plasma.
Cov Yam Cuam Tshuam Rau Lub Sijhawm Sib Cais Platelet
Muaj ntau yam uas cuam tshuam rau lub sijhawm uas siv los cais cov platelets hauv lub centrifuge. Ib qho tseem ceeb yog qhov ceev ntawm lub centrifuge lossis qhov ceev ntawm kev tig. Kev nce qhov ceev ntawm kev tig ua rau lub zog centrifugal ua rau muaj kev sib cais sai dua. Txawm li cas los xij, qhov ceev siab dhau heev yuav ua rau cov platelets puas tsuaj lossis hloov lawv txoj haujlwm. Yog li ntawd, kev ua kom qhov ceev ntawm kev tig yog qhov tseem ceeb kom ua tiav kev sib cais zoo yam tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm platelet.
Lwm yam uas cuam tshuam rau lub sijhawm sib cais yog hom centrifuge siv. Muaj ntau hom, xws li fixed-angle thiab swinging-bucket centrifuges, txhua tus muaj cov qauv tsim sib txawv, rotor configurations, thiab qhov ceev tshaj plaws. Kev xaiv lub centrifuge tsim nyog nyob ntawm qhov xav tau tshwj xeeb ntawm cov txheej txheem sib cais, suav nrog cov platelet xav tau thiab zoo.
Qhov Ntim Qauv thiab Lub Peev Xwm Centrifuge
Qhov ntim ntawm cov qauv uas tab tom ua yog lwm yam tseem ceeb uas txiav txim siab lub sijhawm sib cais. Cov ntim ntau dua feem ntau yuav tsum siv sijhawm ntau dua rau kev sib cais platelet. Cov centrifuges muaj ntau lub peev xwm sib txawv, thiab kev xaiv lub centrifuge tsim nyog raws li qhov loj me ntawm cov qauv uas xav tau tuaj yeem ua kom zoo dua cov txheej txheem sib cais. Kev thauj khoom ntau dhau ntawm lub centrifuge nrog qhov ntim ntau dhau yuav ua rau kev sib cais tsis tiav lossis poob cov qauv, thaum siv lub centrifuge me me tuaj yeem ua rau lub sijhawm sib cais ntev dua lossis ua rau lub cuab yeej puas tsuaj.
Kev cuam tshuam ntawm qhov kub thiab txias ntawm Centrifuge rau kev sib cais Platelet
Cov centrifuges kuj muaj peev xwm tswj qhov kub thiab txias, uas tso cai rau cov neeg siv ua kev sib cais ntawm qhov kub tshwj xeeb. Qhov kub uas xaiv rau kev sib cais platelet nyob ntawm qhov tshwm sim xav tau. Kev txias lub chamber centrifuge yuav pab khaws cov platelets kom muaj sia nyob, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas xav tau kev khaws cia lossis kev ua tom qab. Txawm li cas los xij, qhov kub qis dua yuav ua rau cov qauv viscosity nce ntxiv, cuam tshuam rau kev ua haujlwm sib cais. Yog li ntawd, nrhiav qhov sib npaug zoo ntawm kev tswj qhov kub thiab qhov ceev sib cais yog qhov tseem ceeb.
Kev Hloov Pauv thiab Kev Txhim Kho Daim Ntawv Thov
Kev sib cais cov ntshav platelet los ntawm kev centrifugation pom ntau daim ntawv thov hauv kev tshawb fawb, kev kuaj mob hauv tsev kho mob, thiab cov txheej txheem kho mob. Nyob ntawm seb lub hom phiaj siv li cas, cov txheej txheem tuaj yeem hloov kho kom zoo dua qhov tso zis platelet thiab kev dawb huv. Piv txwv li, cov kws tshawb fawb kawm txog platelet physiology yuav tsom mus rau kev tau txais cov txiaj ntsig siab yam tsis muaj kev cai huv huv, thaum cov kws kho mob ua cov ntshav platelet tso qhov tseem ceeb rau kev dawb huv thiab kev tsis muaj kab mob ntau dua li qhov tso zis.
Xaus lus, centrifugation yog ib qho cuab yeej muaj zog rau kev cais cov platelets ntawm tag nrho cov ntshav, ua rau lawv cais tawm rau ntau yam kev siv downstream. Lub sijhawm sib cais yog cuam tshuam los ntawm cov yam xws li qhov ceev ntawm centrifuge, qhov ntim ntawm cov qauv, lub peev xwm ntawm centrifuge, qhov kub, thiab cov kev xav tau tshwj xeeb. Los ntawm kev nkag siab txog cov kev hloov pauv no thiab kev ua kom zoo dua ntawm cov txheej txheem centrifugation, cov kws tshawb fawb thiab cov kws kho mob tuaj yeem ua tiav kev sib cais platelet zoo thiab txhim khu kev qha.
