ityhubhu yovavanyo lwe-vacuum yonyango yokuqokelela igazi
Inkcazelo emfutshane:
Ityhubhu yovavanyo emfusa ligorha lovavanyo lwenkqubo ye-hematology, kuba i-ethylenediaminetetraacetic acid (EDTA) kuyo inokwenza ngokufanelekileyo i-calcium ion kwisampulu yegazi, isuse i-calcium kwindawo yokusabela, ibhloke kwaye imise inkqubo ye-endogenous Or extrinsic coagulation. ukuthintela ukujiya kwesampulu, kodwa ingenza ukuba i-lymphocyte ibonakale i-nuclei emile okwentyatyambo, kwaye ingavuselela ukudityaniswa kweeplatelet ezixhomekeke kwi-EDTA.Ke ngoko, ayinakusetyenziselwa uvavanyo lwe-coagulation kunye novavanyo lomsebenzi weplatelet.Ngokuqhelekileyo, siyayiguqula kwaye sixube igazi ngokukhawuleza emva kokuqokelelwa kwegazi, kwaye isampuli nayo kufuneka ixutywe phambi kovavanyo, kwaye ayikwazi ukuba i-centrifuged.
Ngoku uqokelelo lwegazi luthandwa kakhulu kwaye lusetyenziswa ngokubanzi, uhlobo lokuqokelela igazi lwetyhubhu yokuqokelela igazi lukhuselekile kwaye lusebenza ngakumbi ekuqokeleleni igazi.Indlela yokugcinwa kwevacuum yokuqokelela uxinzelelo lwegazi olubi isetyenziselwa ukuvavanya igazi elitsalwa ngabantu, kwaye imibala eyahlukeneyo isetyenziselwa ukumela iindlela ezahlukeneyo zokugcina.Ngoko ke zeziphi iindawo ezinokuthi zisetyenziswe uhlobo olutsha lwetyhubhu yokuqokelela igazi kubomi bemihla ngemihla nakwiindawo zonyango?
Ngawaphi amabala ekunokuthi kusetyenziswe kuwo imibhobho yokuqokelela igazi?
1. Ukuqokelela okukhulu kuyafuneka ngexesha lovavanyo lomzimba
Kwiimviwo zomzimba eziququzelelwa zizikolo, iimviwo zomzimba emsebenzini, okanye iimviwo zobuqu, ukutsalwa kwegazi lolunye lweemviwo eziqhelekileyo.Ngoko ke, ukwenzela ukuba kuqinisekiswe ukuchaneka kolwazi lwegazi lwabavavanyi, ityhubhu yokuqokelela igazi isetyenziselwa ukugcina igazi.Ngoko ke, xa kuyimfuneko ukutsala igazi ukuze kuhlolwe abantu ngokomzimba, kuyimfuneko ukusebenzisa uluhlu olukhulu lweetyhubhu zokuqokelela igazi.
2. Ukuqokelelwa kwezikhululo zegazi zothando
Kubomi bemihla ngemihla, sihlala sibona izindlu zokunikela ngegazi ezisecaleni kwendlela kunye neemoto zokunikela ngegazi ezikolweni, zonke ezo ziqokelela iintlobo ezininzi zegazi kwiimfuno zonyango.Ngeli xesha, ityhubhu yokuqokelela igazi iyadingeka ukuqokelela umthombo wegazi obonelelwa luluntu.Indlela encinci kunye nefanelekileyo yokugcina kunye nokugcina inani elikhulu leenqanawa ze-vacuum.
Imfuneko yovavanyo lwaselabhoratri
Ukongeza kwiindawo zonyango, iityhubhu zokuqokelela igazi zisetyenziswa kwiilebhu ezisetyenziselwa uvavanyo lwezonyango.Isebenza njengendawo yokugcina xa kufuneka kwenziwe ulingelo ngegazi.
Okwesine, isikolo esifanelekileyo soqeqesho
Omnye ummandla ukwizikolo zonyango ukuze abafundi bafunde.Kubafundi bezonyango, ukufunda malunga nolwazi olusisiseko lwetyhubhu yokuqokelela igazi kunye nokufunda ukuqokelelwa kwegazi sisisiseko sokufunda, kwaye ukuseta iityhubhu zokuqokelela igazi eziyeleleneyo esikolweni nako kukuba abafundi baqhubeke bephucula ubuchule babo bokuzisebenzisa ngokwesiseko sokuziqhelanisa. .
Ezi ndawo zikhankanywe ngasentla yimida yetyhubhu yokuqokelela igazi enokusetyenziswa.Kufuneka isetyenziswe ngokuchanekileyo kwindawo yonyango, ibonelele ngezixhobo zokufunda kwindawo yesikolo, kwaye yandise umthamo wokugcinwa kwegazi ngaphandle ukulungiselela iimeko eziphuthumayo.Xa ukhetha ezi ndawo, kufuneka uqwalasele ukuba yeyiphi i-vacuum yokuqokelela igazi esemgangathweni ofanelekileyo wokukhetha kunye nokusebenzisa.
