Tshiab injector technology rau CT, MRIthiabAngiographysystems pab txo cov koob tshuaj thiab cia li sau qhov sib piv siv rau cov ntaub ntawv tus neeg mob.
Tsis ntev los no, ntau thiab ntau lub tsev kho mob tau ua tiav txiav cov nqi los ntawm kev siv cov tshuaj txhaj tshuaj sib txawv uas tsim los nrog cov thev naus laus zis siab hauv kev txo qis qhov sib piv pov tseg thiab kev sau cov ntaub ntawv siv tau rau cov koob tshuaj uas tus neeg mob tau txais.
Ua ntej tshaj plaws, cia peb siv ob peb feeb los kawm txog kev sib piv cov xov xwm.
Dab tsi yog qhov sib piv media?
Contrast media yog ib yam tshuaj txhaj rau hauv lub cev los txhim kho qhov sib txawv ntawm lub cev nqaij daim tawv ntawm cov duab. Qhov nruab nrab zoo sib xws yuav tsum ua kom muaj siab heev hauv cov ntaub so ntswg yam tsis muaj kev cuam tshuam tsis zoo.
Hom Contrast Media
Iodine, ib qho ntxhia tau muab rho tawm feem ntau los ntawm cov av, pob zeb thiab brine, feem ntau yog siv hauv kev sib piv xov xwm rau ob qho tib si CT thiab X-ray duab. Lodinated contrast media yog cov neeg siv ntau tshaj plaws, nrog CT xav tau qhov loj tshaj plaws tag nrho. Tag nrho cov tam sim no siv suav tomography (CT) cov neeg ua haujlwm sib txawv yog ua raws li lub nplhaib triiodinated benzene. Thaum lub iodine atom yog lub luag hauj lwm rau lub radiopacity ntawm qhov sib piv xov xwm, cov organic carrier yog lub luag hauj lwm rau nws lwm yam khoom, xws li osmolality, tonicity, hydrophilicity, thiab viscosity. Cov neeg nqa khoom organic yog lub luag haujlwm rau feem ntau ntawm cov teebmeem tsis zoo thiab tau txais kev saib xyuas los ntawm cov kws tshawb fawb. Qee tus neeg mob hnov mob me me ntawm qhov sib piv xov xwm, tab sis feem ntau ntawm cov teebmeem tshwm sim yog kho los ntawm qhov loj osmotic load. Yog li, ob peb lub xyoo dhau los cov kws tshawb fawb tau tsom mus rau kev tsim cov xov xwm sib txawv uas txo qis osmotic load tom qab kev tswj hwm tus neeg sawv cev sib txawv.
Contrast media injectors yog dab tsi?
Contrast injectors yog cov cuab yeej kho mob uas ua haujlwm rau kev txhaj tshuaj zoo sib xws rau hauv lub cev txhawm rau txhim kho qhov pom ntawm cov ntaub so ntswg rau kev kho mob cov txheej txheem.(Muab lub CT ob lub taub hau siab injector ua piv txwv, saib daim duab hauv qab no :)
Yuav ua li cas cov thev naus laus zis tshiab tshaj plaws hauvsiab injectorpab txo cov khib nyiab ntawm qhov sib piv media thaum txhaj tshuaj?
1.Automated Injector Systems
Automated injector systems tuaj yeem tswj hwm tus nqi sib piv siv, uas muaj peev xwm tshiab rau cov tuam haujlwm hluav taws xob saib xyuas kom yooj yim thiab sau lawv qhov sib piv kev siv xov xwm. Nrog rau kev txhim kho thev naus laus zis, lubsiab injectorstau hloov zuj zus los ntawm cov phau ntawv yooj yim injectors mus rau automated systems uas tsis tsuas yog tswj tus nqi ntawm qhov sib piv xov xwm tus neeg sawv cev siv, tab sis kuj pab txhawb automated cov ntaub ntawv sau thiab tus kheej koob tshuaj rau txhua tus neeg mob.
LnkMedtau tsim tshwj xeeb sib txawv injectors rau cov txheej txheem intravenous hauv Computed Tomography (CT) thiab Magnetic Resonance Imaging (MRI) thiab rau cov txheej txheem intraarterial hauv plawv thiab peripheral cuam tshuam. Tag nrho plaub hom kev txhaj tshuaj no tso cai rau kev txhaj tshuaj tsis siv neeg. Kuj tseem muaj qee qhov kev ua haujlwm tsis siv neeg tsim los ua kom yooj yim rau kev noj qab haus huv cov neeg ua haujlwm thiab txhim kho kev nyab xeeb, xws li tsis siv neeg sau thiab priming, tsis siv neeg plunger ua ntej thiab thim rov qab thaum txuas thiab tshem cov koob txhaj tshuaj. Lub ntim precision tuaj yeem poob mus rau 0.1mL, ua kom cov koob meej ntau dua ntawm qhov sib piv nruab nrab txhaj tshuaj.
2. Syringeless Injectors
Syringeless hwj chim injectors tau tshwm sim los ua ib qho kev daws teeb meem los txo qhov sib piv cov ntaub ntawv pov tseg. Qhov kev xaiv no muab lub sijhawm los siv cov xov xwm sib txawv raws li qhov ua tau. Thaum Lub Peb Hlis 2014, Guerbet launched FlowSens, nws cov koob txhaj tshuaj tsis pub txhaj tshuaj muaj li ntawm lub hnab mos thiab cov khoom siv pov tseg, siv lub tshuab hydraulic, cov tshuaj tsis pub txhaj tshuaj kom xa cov xov xwm sib piv; Bracco tus tshiab "ntse" Ua kom muaj zog syringless injectors tuaj yeem siv txhua qhov poob. ntawm qhov sib txawv loaded rau hauv lub system rau siab tshaj plaws kev lag luam. Txog tam sim no, lawv cov qauv tsim tau ua pov thawj tias cov tshuaj txhaj tshuaj tsis muaj zog tau siv ntau dua thiab ua haujlwm tau zoo dua li ob lub koob txhaj tshuaj lub zog txhaj tshuaj, nrog ntau cov pov tseg ntawm qhov sib piv-txhim kho CT pom rau yav tom ntej. Lub syringeless injector kuj tso cai rau tus nqi txuag ntawm $ 8 ib tus neeg mob thaum xav txog tus nqi qis thiab txhim kho kev ua haujlwm ntawm cov cuab yeej.
Raws li tus neeg muag khoom,LnkMedua rau kev txuag nqi rau nws cov neeg siv khoom yog qhov tseem ceeb tshaj plaws. Peb tau cog lus los tsim cov khoom lag luam zoo, nyab xeeb thiab kev lag luam ntau dua los ntawm kev tsim kho thev naus laus zis kom txuag nqi rau peb cov neeg siv khoom.
