1. Kev xaiv thiab ntau npaum li cas ntawm anticoagulant
1.1 Xaiv cov tshuaj tiv thaiv coagulant: Nws raug nquahu kom xaiv heparin ua cov tshuaj tiv thaiv coagulant.Oxalate los yog sodium citrate tuaj yeem ua rau cov cell shrinkage zoo cuam tshuam rau kev sib sau thiab deformability ntawm cov qe ntshav liab, ua rau cov ntshav viscosity nce, yog li nws tsis haum rau kev siv.
1.1.2 Dosage of anticoagulant: heparin anticoagulant concentration yog 10-20IU/mL ntshav, theem khoom lossis theem siab concentration kua yog siv rau anticoagulation Agent.Yog tias cov kua tshuaj anticoagulant siv ncaj qha, nws cov nyhuv dilution ntawm cov ntshav yuav tsum raug txiav txim siab.Tib batch ntawm kev sim yuav tsum
Siv tib cov tshuaj tiv thaiv coagulant nrog tib batch tooj.
1.3 Kev tsim cov raj tshuaj tiv thaiv kab mob: yog siv cov kua theem anticoagulant, nws yuav tsum muab tso rau hauv lub khob qhuav los yog lub raj mis iav thiab ziab hauv qhov cub Tom qab ziab, qhov ziab kom qhuav yuav tsum tswj tsis pub tshaj 56 ° C.
Lus Cim: Tus nqi ntawm cov tshuaj tiv thaiv coagulant yuav tsum tsis txhob loj heev kom txo cov nyhuv dilution ntawm cov ntshav;Tus nqi ntawm anticoagulant yuav tsum tsis txhob tsawg dhau, txwv tsis pub nws yuav ncav cuag tsis muaj cov nyhuv anticoagulant.
2. Qauv sau
2.1 Lub Sij Hawm: Feem ntau, cov ntshav yuav tsum tau sau thaum sawv ntxov ntawm lub plab khoob thiab nyob hauv lub xeev ntsiag to.
2.2 Qhov chaw: Thaum noj ntshav, zaum zaum thiab nqa cov ntshav los ntawm venous anterior luj tshib.
2.3 Txo lub sij hawm thaiv venous kom ntau li ntau tau thaum sau ntshav.Tom qab rab koob tau tho rau hauv cov hlab ntsha, tam sim ntawd loosen lub cuff kom nyob ntsiag to li 5 vib nas this kom pib sau ntshav.
2.4 Cov txheej txheem sau cov ntshav yuav tsum tsis txhob nrawm dhau, thiab yuav tsum tsis txhob muaj kev puas tsuaj rau cov qe ntshav liab uas tshwm sim los ntawm lub zog shearing.Rau qhov no, lub lancet lub puab txoj kab uas hla ntawm lub taub yog zoo dua (nws yog zoo dua mus siv ib rab koob saum 7 gauge).Nws tsis pom zoo kom kos lub zog ntau dhau thaum sau cov ntshav, kom tsis txhob muaj lub zog shearing txawv txav thaum cov ntshav ntws los ntawm rab koob.
2.2.5 Kev sib xyaw ua ke: Tom qab cov ntshav tau sau tseg, rub lub koob txhaj tshuaj, thiab maj mam txhaj cov ntshav mus rau hauv lub raj tshuaj ntsuam raws phab ntsa ntawm lub raj kuaj, thiab tom qab ntawd tuav lub nruab nrab ntawm lub raj ntsuas nrog koj txhais tes thiab rub nws los yog xaub nws mus rau hauv ib lub voj voog ntawm lub rooj kom cov ntshav sib xyaw nrog cov tshuaj tiv thaiv coagulant.
Txhawm rau kom tsis txhob muaj ntshav txhaws, tab sis tsis txhob ua kom muaj zog kom tsis txhob hemolysis.
3. Kev npaj cov ntshav ntshav
Kev npaj plasma txais cov txheej txheem kev kho mob niaj hnub, lub zog centrifugal yog li 2300 × g rau 30 feeb, thiab txheej txheej sab saud ntawm cov ntshav tau muab rho tawm, rau kev ntsuas ntshav viscosity.
4. Qauv tso
4.1 Cia qhov kub thiab txias: cov qauv tsis tuaj yeem khaws cia hauv qab 0 ° C.Nyob rau hauv cov xwm txheej khov, nws yuav cuam tshuam rau lub cev lub cev ntawm cov ntshav.
Lub xeev thiab rheological zog.Yog li ntawd, cov ntshav kuaj feem ntau yog khaws cia ntawm chav tsev kub (15 ° C-25 ° C).
4.2 Lub sij hawm muab tso rau: Cov qauv feem ntau raug kuaj hauv 4 teev ntawm chav tsev kub, tab sis yog tias cov ntshav tau noj tam sim ntawd, uas yog hais, yog tias qhov ntsuas tau ua tiav, qhov txiaj ntsig ntawm qhov ntsuas tau qis.Yog li ntawd, nws yog qhov tsim nyog cia qhov kev ntsuam xyuas sawv ntsug li 20 feeb tom qab noj cov ntshav.
4.3 Cov khoom tsis tuaj yeem khov thiab khaws cia hauv qab 0 ° C.Thaum cov ntshav kuaj yuav tsum tau khaws cia rau lub sijhawm ntev dua nyob rau hauv cov xwm txheej tshwj xeeb, lawv yuav tsum tau muab tso rau hauv lub tub yees ntawm 4 ℃, thiab lub sijhawm khaws cia feem ntau tsis pub tshaj 12 teev.Khaws cov khoom kom txaus ua ntej kev sim, Co kom zoo, thiab cov xwm txheej cia yuav tsum tau qhia hauv daim ntawv tshaj tawm.
