Idivayisi yokuqoqa igazi levacuum inezingxenye ezintathu: ishubhu lokuqoqa igazi, inaliti yokuqoqa igazi (okuhlanganisa inaliti eqondile kanye nenaliti yokuqoqa igazi esikhunjeni), kanye nesibambi senaliti.Ishubhu lokuqoqa igazi le-vacuum liyingxenye yalo eyinhloko, esetshenziselwa ikakhulukazi ukuqoqa nokulondoloza igazi.Inani elithile lokucindezela okungalungile lihlelwa kusengaphambili enqubweni yokukhiqiza.Lapho inaliti yokuqoqa igazi ibhotshozwa emithanjeni yegazi, ngenxa yokucindezela okungekuhle eshubhuni lokuqoqa igazi, igazi ligelezela ngokuzenzakalelayo eshubhu lokuqoqa igazi.Ethunjini lokuqoqa igazi;ngesikhathi esifanayo, izithasiselo ezihlukahlukene zisethwa kusengaphambili eshubhu lokuqoqa igazi, elingahlangabezana ngokugcwele nenani lokuhlolwa kwegazi lomtholampilo eliphelele, futhi liphephile, livaliwe futhi lilungele ukuthuthwa.
Vacuum amashubhu okuqoqa igazingokuvamile zihlukaniswa zibe izigaba ezilandelayo:
1. Ishubhu eyomile engenalutho ngaphandle kwezithasiselo: Udonga lwangaphakathi lweshubhu lokuqoqa igazi luboshwe ngokulinganayo ngomuthi (amafutha e-silicon) ukuvimbela ukulenga odongeni.Isebenzisa umgomo wokugoqa kwegazi wemvelo ukuze ihlanganise igazi, futhi ngemva kokuba i-serum imvula ngokwemvelo, i-centrifuged ukuze isetshenziswe.Ikakhulu isetshenziselwa i-serum biochemistry (ukusebenza kwesibindi, ukusebenza kwezinso, i-enzyme ye-myocardial, i-amylase, njll.), ama-electrolyte (i-serum potassium, i-sodium, i-chloride, i-calcium, i-phosphorus, njll.), umsebenzi wegilo, ukuhlolwa kwezidakamizwa, ukuhlolwa kwe-AIDS, izimpawu zesimila, i-serum immunity ifunde.
2. I-coagulation tube: Udonga lwangaphakathi lweshubhu lokuqoqa igazi luhlanganiswe ngokulinganayo ngamafutha abicah ukuvimbela ukulenga odongeni, futhi i-coagulant yengezwa ngesikhathi esifanayo.Ama-coagulant angenza i-fibrin isebenze, aguqule i-fibrin e-soluble ibe ama-fibrin aggregate angenakunyakaziswa, bese enza amahlule e-fibrin azinzile.Uma ufuna ukuthola imiphumela ngokushesha, ungasebenzisa amashubhu e-coagulation.Ngokuvamile isetshenziselwa i-biochemistry ephuthumayo.
3. Ishubhu yokuqoqa igazi equkethe ijeli yokuhlukanisa kanye ne-coagulant: udonga lweshubhu lufakwe i-siliconized futhi lumbozwe nge-coagulant ukusheshisa ukuhlangana kwegazi futhi lufinyeze isikhathi sokuhlola.Ijeli yokuhlukanisa yengezwa ku-tube.Ijeli yokuhlukanisa inobudlelwane obuhle ne-PET tube, futhi idlala indima ekuhlukaniseni.Ngokuvamile, ngisho nakuma-centrifuge avamile, ijeli yokuhlukanisa ingahlukanisa izingxenye eziwuketshezi (i-serum) kanye nezingxenye eziqinile (amangqamuzana egazi) egazini.Hlukanisa ngokuphelele futhi uqoqe ku-tube ukuze wenze umgoqo.Awekho amaconsi kawoyela akhiqizwa ku-serum ngemuva kwe-centrifugation, ngakho-ke ayiwuvali umshini.Ikakhulu isetshenziselwa i-serum biochemistry (ukusebenza kwesibindi, ukusebenza kwezinso, i-enzyme ye-myocardial, i-amylase, njll.), ama-electrolyte (i-serum potassium, i-sodium, i-chloride, i-calcium, i-phosphorus, njll.), umsebenzi wegilo, ukuhlolwa kwezidakamizwa, ukuhlolwa kwe-AIDS, izimpawu zesimila, i-serum immunity ifunde.
