Isampula yegazi levacuum inezingxenye ezintathu: isitsha sokuqoqa igazi, inaliti yokuqoqa igazi (okuhlanganisa inaliti eqondile kanye nenaliti yokuqoqa igazi esikhunjeni), kanye nesibambi senaliti.Ishubhu lokuqoqa igazi le-vacuum liyingxenye eyinhloko, esetshenziselwa ikakhulukazi ukuqoqa nokulondoloza igazi.Inani elithile lokucindezela okungalungile lihlelwa kusengaphambili enqubweni yokukhiqiza.Lapho inaliti yokuqoqa igazi ingena emthanjeni wegazi, ngenxa yokucindezela okungekuhle eshubhuni lokuqoqa igazi, igazi ligeleza ngokuzenzakalelayo eshubhu lokuqoqa igazi;Ngesikhathi esifanayo, izithasiselo ezihlukahlukene zisethwa kusengaphambili ku-tube yokuqoqa igazi, engahlangabezana ngokugcwele nezidingo zokuhlolwa kwegazi okubanzi emtholampilo, futhi iphephile, ivaliwe futhi ilungele ukuthuthwa.
Vacuum ishubhu lokuqoqa igazi kanye nezithasiselo
Imithambo ye-vacuum yokuqoqa igazi ngokuvamile ihlukaniswa ngezigaba ezilandelayo:
1. Ithubhu eyomile engenalutho ngaphandle kwezithasiselo: udonga lwangaphakathi lwethubhu yokuqoqa igazi luhlanganiswe ngokulinganayo ne-ejenti (amafutha e-silicone) ukuvimbela ukulenga odongeni.Isebenzisa umgomo wokuhlangana kwegazi okungokwemvelo ukwenza igazi lijiye, futhi ikhulise i-serum ngemva kokuba imvula ngokwemvelo.Isetshenziselwa ikakhulukazi 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, ukutholwa kwezidakamizwa, ukutholwa kwe-AIDS, isimila. izimpawu, kanye ne-serum immunology.
2. I-Coagulation promoting tube: udonga lwangaphakathi lweshubhu lokuqoqa igazi luhlanganiswe ngokulinganayo ngamafutha abicah ukuvimbela ukulenga odongeni, futhi i-Desheng coagulant yengezwa.I-coagulant ingenza i-fibrin protease isebenze, yenze i-fibrin encibilikayo ibe i-fibrin polymer enganyibiliki, bese yenza ihlule le-fibrin elizinzile.Uma ufuna ukuthola imiphumela ngokushesha, ungasebenzisa i-coagulant tube.Ngokuvamile isetshenziselwa i-biochemistry ephuthumayo.
3. Ishubhu yokuqoqa igazi equkethe ijeli ehlukanisayo kanye ne-coagulant: udonga lweshubhu lwenziwe i-sililic futhi lumbozwe nge-coagulant ukusheshisa ukuhlangana kwegazi futhi lufinyeze isikhathi sokuhlola.Ijeli yokuhlukanisa yengezwa ku-tube.Ijeli yokuhlukanisa inobudlelwano obuhle ne-PET tube futhi idlala indima yokuhlukaniswa.Ngokuvamile, ngisho nakwi-centrifuge evamile, ijeli yokuhlukanisa i-serum ye-Desheng ingakwazi ukuhlukanisa ngokuphelele izingxenye eziwuketshezi (i-serum) nezingxenye eziqinile (amangqamuzana egazi) egazini futhi zinqwabelane eshubhu lokuhlola ukuze zenze umgoqo.Akukho ukwehla kwamafutha ku-serum ngemva kwe-centrifugation, ngakho umshini ngeke uvinjelwe.Isetshenziselwa ikakhulukazi 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, ukutholwa kwezidakamizwa, ukutholwa kwe-AIDS, isimila. izimpawu, kanye ne-serum immunology.
