Cov ntshav ncig thoob plaws lub cev, muab cov as-ham rau txhua qhov chaw thiab tshem tawm cov khib nyiab, yog li nws yuav tsum tau tswj hwm nyob rau hauv qhov xwm txheej ib txwm muaj. Txawm li cas los xij, thaum cov hlab ntsha raug mob thiab tawg, lub cev yuav tsim ntau yam kev tsis haum, suav nrog vasoconstriction kom txo cov ntshav poob, platelet aggregation los thaiv qhov txhab kom tsis txhob los ntshav, thiab kev ua haujlwm ntawm cov coagulation factors los tsim cov thrombus ruaj khov dua los thaiv cov ntshav tawm thiab Lub hom phiaj ntawm kev kho cov hlab ntsha yog lub cev lub cev hemostasis mechanism.

Yog li ntawd, lub cev cov nyhuv hemostatic tuaj yeem muab faib ua peb ntu. Thawj ntu yog tsim los ntawm kev sib cuam tshuam ntawm cov hlab ntsha thiab platelets, uas hu ua thawj hemostasis; qhov thib ob yog kev ua haujlwm ntawm cov coagulation factors, thiab kev tsim cov reticulated coagulation fibrin, uas qhwv cov platelets thiab dhau los ua ib qho thrombus ruaj khov, uas hu ua secondary hemostasis, uas yog Qhov peb hu ua coagulation; txawm li cas los xij, thaum cov ntshav nres thiab tsis ntws tawm, lwm qhov teeb meem tshwm sim hauv lub cev, uas yog, cov hlab ntsha raug thaiv, uas yuav cuam tshuam rau cov ntshav, yog li qhov thib peb ntawm hemostasis yog Cov nyhuv yaj ntawm thrombus yog tias thaum cov hlab ntsha ua tiav cov nyhuv ntawm hemostasis thiab kho, thrombus yuav yaj kom rov qab tau cov ntshav ntws zoo.

Pom tau tias qhov kev coagulation yog ib feem ntawm hemostasis. Lub cev hemostasis yog qhov nyuaj heev. Nws tuaj yeem ua haujlwm thaum lub cev xav tau nws, thiab thaum cov ntshav coagulation tau ua tiav nws lub hom phiaj, nws tuaj yeem yaj cov thrombus hauv lub sijhawm tsim nyog thiab rov zoo. Cov hlab ntsha raug thaiv kom lub cev tuaj yeem ua haujlwm li qub, uas yog lub hom phiaj tseem ceeb ntawm hemostasis.

Cov kab mob ntshav feem ntau poob rau hauv ob pawg hauv qab no:

​

1. Cov hlab ntsha thiab cov ntshav tsis zoo

Piv txwv li: vasculitis lossis cov ntshav platelets qis, cov neeg mob feem ntau muaj cov pob me me los ntshav hauv qab qis, uas yog purpura.

​

2. Cov yam ntxwv tsis sib xws ntawm cov ntshav coagulation

Xws li cov kab mob hemophilia uas muaj txij thaum yug los thiab cov kab mob Wein-Weber lossis cov kab mob siab cirrhosis uas tau txais los, lom nas, thiab lwm yam, feem ntau muaj cov pob khaus ecchymosis loj heev ntawm lub cev, lossis cov ntshav tawm hauv cov leeg nqaij tob.

Yog li ntawd, yog tias koj muaj cov ntshav tsis zoo li saum toj no, koj yuav tsum sab laj nrog kws kho mob ntshav sai li sai tau.
