Isixhobo sokuqokelela igazi se-vacuum sineenxalenye ezintathu: ityhubhu yokuqokelela igazi, inaliti yokuqokelela igazi (kubandakanywa inaliti ethe tye kunye ne-scalp yokuqokelela igazi), kunye nesibambi senaliti.Ityhubhu yokuqokelela igazi ye-vacuum iyona nxalenye yayo ephambili, esetyenziselwa ukuqokelela igazi kunye nokugcinwa.Umlinganiselo othile woxinzelelo olubi lusetwa kwangaphambili kwinkqubo yokuvelisa.Xa inaliti yokuqokelela igazi ihlatywa kumthambo wegazi, ngenxa yoxinzelelo olubi kwityhubhu yokuqokelela igazi, igazi liqukuqela ngokuzenzekelayo kwityhubhu yokuqokelela igazi.Kwityhubhu yokuqokelela igazi;kwangaxeshanye, izongezo ezahlukeneyo zisetwe kwangaphambili kwityhubhu yokuqokelela igazi, enokudibana ngokupheleleyo nenani leemvavanyo zegazi zeklinikhi ezibanzi, kwaye ikhuselekile, ivaliwe kwaye ilungele ukuthuthwa.
Vacuum iityhubhu zokuqokelela igazi' iindidi
1. Ityhubhu engenanto eyomileyo ngaphandle kwezongezo: Udonga lwangaphakathi lwetyhubhu yokuqokelela igazi luhlanganiswe ngokulinganayo kunye neyeza (ioli ye-silicon) ukukhusela udonga.Isebenzisa umgaqo-nkqubo wendalo we-coagulation yegazi ukuze idibanise igazi, kwaye emva kokuba i-serum iyancipha ngokwemvelo, i-centrifuged ukuze isetyenziswe.Isetyenziswa kakhulu 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, uvavanyo lweziyobisi, ukuvavanywa kwe-AIDS, iimpawu ze-tumor, funda i-serum immunity.
2. I-tube ye-coagulation: Udonga lwangaphakathi lombhobho wokuqokelela igazi lufakwe ngokulinganayo ngeoli ye-silicone ukukhusela ukuxhoma udonga, kwaye i-coagulant yongezwa ngexesha elifanayo.Iicoagulants zinokuvula i-fibrin, zijike i-soluble fibrin zibe zii-insoluble fibrin aggregates, emva koko zenze amahlwili efibrin azinzileyo.Ukuba ufuna ukufumana iziphumo ngokukhawuleza, ungasebenzisa i-coagulation tubes.Ngokuqhelekileyo isetyenziselwa i-biochemistry engxamisekileyo.
3. I-tube yokuqokelela igazi equkethe i-gel yokwahlula kunye ne-coagulant: udonga lwe-tube lufakwe i-siliconized kwaye lufakwe nge-coagulant ukukhawuleza ukudibanisa kwegazi kunye nokunciphisa ixesha lokuvavanya.I-gel yokwahlula yongezwa kwi-tube.Ijeli yokwahlula inobudlelwane obuhle kunye ne-PET ityhubhu, kwaye idlala indima yodwa.Ngokuqhelekileyo, nakwii-centrifuges eziqhelekileyo, ijeli yokwahlula inokwahlula izinto ezingamanzi (i-serum) kunye namalungu aqinileyo (iiseli zegazi) egazini.Ukwahlula ngokupheleleyo kwaye uqokelele kwi-tube ukwenza umqobo.Akukho maconsi eoli avelisiweyo kwi-serum emva kwe-centrifugation, ngoko ayiwuvali umatshini.Isetyenziswa kakhulu 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, uvavanyo lweziyobisi, ukuvavanywa kwe-AIDS, iimpawu ze-tumor, funda i-serum immunity.
