lub zog centrifugal siv los cais cov ntshav

Kev Taw Qhia

Lub zog centrifugal yog ib lub tswv yim tseem ceeb hauv physics uas ua lub luag haujlwm tseem ceeb hauv ntau yam lag luam, suav nrog tshuaj thiab kev kho mob. Hauv kev kuaj mob, lub zog centrifugal yog siv los cais cov khoom ntshav kom ua ntau yam kev kuaj mob, xws li suav cov qe ntshav, ntaus cov ntshav, thiab kev tshuaj xyuas cov cim tshuaj sib txawv. Tsab xov xwm no lub hom phiaj yog piav qhia txog lub zog centrifugal yog dab tsi, nws tsim li cas, thiab nws siv li cas los cais cov khoom ntshav kom zoo.

1. Nkag Siab Txog Lub Zog Centrifugal

Lub zog centrifugal yog lub zog cuav uas zoo li ua rau lub cev txav mus rau hauv txoj kev voj voog. Txawm hais tias nws zoo li lub zog rub cov khoom tawm ntawm qhov chaw nruab nrab ntawm kev tig, nws yog, qhov tseeb, lub zog sab nraud los ntawm lub zog inertia ntawm ib yam khoom. Vim tias ntshav yog ib yam khoom ua kua, nws ua raws li cov ntsiab cai ntawm cov kua dej dynamics, ua rau nws tsim nyog rau kev sib cais siv lub zog centrifugal.

2. Cov Tshuab Centrifuge: Saib Ze Dua

Cov tshuab centrifuge yog cov khoom siv tshwj xeeb uas siv thoob plaws ntau qhov chaw kho mob los cais cov khoom ntshav. Cov tshuab no ua haujlwm raws li lub hauv paus ntsiab lus ntawm lub zog centrifugal thiab muaj lub rotor sib dhos uas tig nrog kev kub ceev. Cov qauv ntshav raug muab tso rau hauv cov raj lossis cov thawv hauv lub rotor thiab raug tig hnyav, ua rau nws cov khoom sib cais.

3. Cov Ntshav Muaj Dab Tsi

Ua ntej yuav nkag siab txog cov txheej txheem ntawm kev sib cais cov ntshav siv lub zog centrifugal, nws yog ib qho tseem ceeb kom nkag siab txog cov ntshav. Cov ntshav muaj ntau yam sib txawv, suav nrog cov qe ntshav liab (erythrocytes), cov qe ntshav dawb (leukocytes), platelets (thrombocytes), thiab plasma. Cov khoom no muaj qhov sib txawv thiab qhov loj me, ua rau lawv yooj yim rau kev sib cais los ntawm centrifugation.

4. Cov Txheej Txheem ntawm Kev Sib Cais Ntshav

Cov txheej txheem cais cov ntshav muaj ntau kauj ruam los xyuas kom meej tias nws cov khoom sib cais tau zoo. Ua ntej, cov qauv ntshav raug sau los ntawm tus neeg mob siv lub koob txhaj tshuaj lossis lub raj tshwj xeeb sau. Tom qab ntawd, cov qauv ntshav raug xa mus rau hauv cov raj uas tsim tshwj xeeb rau kev centrifugation. Cov raj no feem ntau muaj cim nrog qhov ceev tshaj plaws uas lawv tuaj yeem centrifuged kom tsis txhob puas tsuaj.

5. Xaiv Qhov Ceev thiab Lub Sijhawm Centrifuge Tsim Nyog

Yuav kom ua tiav qhov kev sib cais zoo tshaj plaws ntawm cov khoom xyaw ntawm cov ntshav, nws yog ib qho tseem ceeb heev uas yuav tsum xaiv qhov ceev thiab lub sijhawm tsim nyog rau kev centrifugation. Cov khoom xyaw ntawm cov ntshav sib txawv muaj qhov sib txawv ntawm qhov ceev thiab qhov loj me, uas yuav tsum muaj cov kev ntsuas centrifugation sib txawv. Piv txwv li, yog tias muaj cov qe ntshav yooj yim, qhov ceev qis dua thiab lub sijhawm luv dua yuav txaus, thaum cov kev kuaj mob nyuaj dua yuav xav tau qhov ceev siab dua thiab lub sijhawm ntev dua.

6. Cov Txheej Txheem Sib Cais

Thaum cov raj uas muaj cov ntshav kuaj tau muab tso rau hauv lub centrifuge kom ruaj khov, lub rotor pib tig sai sai. Qhov kev txav tig ua rau muaj lub zog centripetal uas thawb cov ntshav ntom ntom mus rau hauv qab ntawm lub raj, thaum cov ntshav ntom ntom tsawg dua tseem nyob ze rau sab saum toj. Ua li no, cov ntshav sib cais ua ntau txheej sib txawv, uas tuaj yeem nkag mus thiab soj ntsuam tau yooj yim.

7. Nrhiav thiab Tshuaj Xyuas Cov Cheebtsam Ntshav Sib Cais

Tom qab ua tiav cov txheej txheem centrifugation, cov khoom sib cais ntawm cov ntshav tuaj yeem rov qab tau zoo siv lub pipette lossis lwm yam cuab yeej tshwj xeeb. Cov txheej, suav nrog cov qe ntshav liab uas tau ntim rau hauv qab, lub tsho buffy (ib txheej nyias ntawm cov qe ntshav dawb thiab platelets), thiab cov plasma nyob rau sab saum toj, ces raug kuaj xyuas ntxiv thiab kuaj mob.

Xaus lus

Lub zog centrifugal yog ib qho tseem ceeb uas siv rau hauv cov chaw kuaj mob thiab cov chaw kho mob kom cais cov ntshav tau zoo. Los ntawm kev siv lub zog ntawm centrifugation, cov kws kho mob tuaj yeem tau txais cov ntaub ntawv tseem ceeb txog kev noj qab haus huv ntawm tus neeg mob thiab ua qhov kev kuaj mob kom raug. Kev nkag siab txog lub zog centrifugal ua haujlwm li cas thiab nws siv rau hauv kev cais cov ntshav ua rau cov kws kho mob muab kev saib xyuas tus neeg mob zoo dua thiab txhim kho cov txiaj ntsig kev kho mob.
