Isampulu yegazi levacuum inamacandelo amathathu: isitya sokuqokelela igazi, inaliti yokuqokelela igazi (kubandakanya inaliti ethe tye kunye nentloko yenaliti yokuqokelela igazi), kunye nesibambi senaliti.Ityhubhu yokuqokelela igazi ye-vacuum iyona nxalenye ephambili, esetyenziselwa kakhulu ukuqokelela kunye nokugcinwa kwegazi.Umlinganiselo othile woxinzelelo olubi lusetwa kwangaphambili kwinkqubo yokuvelisa.Xa inaliti yokuqokelela igazi ingena kumthambo wegazi, ngenxa yoxinzelelo olubi kwityhubhu yokuqokelela igazi, igazi liqukuqela ngokuzenzekelayo kwityhubhu yokuqokelela igazi;Kwangaxeshanye, izongezo ezahlukahlukeneyo zisetwe kwangaphambili kwityhubhu yokuqokelela igazi, enokuhlangabezana ngokupheleleyo neemfuno zovavanyo lwegazi olubanzi olubanzi eklinikhi, kwaye ikhuselekile, ivaliwe kwaye ilungele ukuthuthwa.
Vacuum ityhubhu yokuqokelela igazi kunye nezongezo
Imithanjana yokuqokelela igazi ivacuum yohlulwe ngokwezi ndidi zilandelayo:
1. I-tube engenanto eyomileyo ngaphandle kwezongezo: udonga lwangaphakathi lwetyhubhu yokuqokelela igazi luhlanganiswe ngokulinganayo kunye ne-agent (ioli ye-silicone) ukukhusela udonga.Isebenzisa umgaqo wendalo wokudityaniswa kwegazi ukwenza igazi lijiye, kunye ne-centrifuges yeserum emva kokuba imanzi ngokwemvelo.Isetyenziselwa ikakhulu kwi-serum biochemistry (umsebenzi wesibindi, umsebenzi wezintso, i-enzyme ye-myocardial, i-amylase, njl.), i-electrolytes (i-serum potassium, i-sodium, i-chloride, i-calcium, i-phosphorus, njl.), umsebenzi we-thyroid, ukufunyanwa kweziyobisi, ukufumanisa i-AIDS, i-tumor. abamakishi, kunye ne-serum immunology.
2. I-tube yokukhuthaza i-coagulation: udonga lwangaphakathi lwetyhubhu yokuqokelela igazi lufakwe ngokulinganayo ngeoli ye-silicone ukukhusela ukuxhoma eludongeni, kunye ne-Desheng coagulant yongezwa.I-coagulant inokuvula i-fibrin protease, yenze i-fibrin enyibilikayo ibe yi-insoluble fibrin polymer, emva koko yenze ihlwili lefibrin elizinzileyo.Ukuba ufuna ukufumana iziphumo ngokukhawuleza, ungasebenzisa ityhubhu ye-coagulant.Ngokuqhelekileyo isetyenziselwa i-biochemistry engxamisekileyo.
3. I-tube yokuqokelela igazi equkethe i-gel yokwahlula kunye ne-coagulant: udonga lwe-tube lufakwe i-silicified kwaye lufakwe kwi-coagulant ukukhawulezisa i-coagulation yegazi kunye nokunciphisa ixesha lokuvavanya.I-gel yokwahlula yongezwa kwi-tube.Ijeli yokwahlula inobudlelwane obuhle kunye ne-PET ityhubhu kwaye idlala indima yodwa.Ngokubanzi, nakwi-centrifuge eqhelekileyo, ijeli yokwahlula i-serum ye-Desheng inokwahlula ngokupheleleyo izinto ezingamanzi (i-serum) kunye namacandelo aqinileyo (iiseli zegazi) egazini kwaye ziqokelele kwityhubhu yovavanyo ukwenza umqobo.Akukho kwehla kweoli kwi-serum emva kwe-centrifugation, ngoko umatshini awuyi kuvinjelwa.Isetyenziselwa ikakhulu kwi-serum biochemistry (umsebenzi wesibindi, umsebenzi wezintso, i-enzyme ye-myocardial, i-amylase, njl.), i-electrolytes (i-serum potassium, i-sodium, i-chloride, i-calcium, i-phosphorus, njl.), umsebenzi we-thyroid, ukufunyanwa kweziyobisi, ukufumanisa i-AIDS, i-tumor. abamakishi, kunye ne-serum immunology.
