Izitayela zakamuva ze-High Pressure Injectors zisiza ekunciphiseni imfucuza engafani

Ubuchwepheshe obusha bokufaka injector CT, I-MRIfuthiI-Angiographyizinhlelo zisiza ukunciphisa umthamo futhi ziqopha ngokuzenzakalelayo umehluko osetshenziselwa irekhodi lesiguli.

Muva nje, izibhedlela eziningi zinciphise ngempumelelo izindleko ngokusebenzisa ama-contrast injector aklanywe ngobuchwepheshe obuthuthukisiwe ekunciphiseni imfucuza ye-contrast kanye nokuqoqwa kwedatha okuzenzakalelayo komthamo isiguli esiwutholayo.

Okokuqala, ake sithathe imizuzu embalwa sifunde ngemidiya yokuqhathanisa.

Kuyini imidiya ephikisanayo?

I-contrast media iyisithako esifakwa emzimbeni ukuze kuthuthukiswe umehluko phakathi kwezicubu zomzimba ezithombeni. I-contrast medium efanele kufanele ifinyelele ukugxila okuphezulu kakhulu ezicutshini ngaphandle kokukhiqiza imiphumela emibi.

Izinhlobo ze-Contrast Media

I-iodine, iminerali ekhishwe ngokuyinhloko enhlabathini, edwaleni kanye nasemanzini acwebezelayo, ivame ukusetshenziswa kwimidiya yokuqhathanisa kokubili i-CT kanye ne-X-ray imaging. Imidiya yokuqhathanisa elodiniwe yizona zinto ezisetshenziswa kakhulu, kanti i-CT idinga inani elikhulu kunawo wonke. Zonke izinto zokuqhathanisa ezisetshenziswa njengamanje ezisebenzisa i-computed tomography (CT) zisekelwe ku-triiodinated benzene ring. Ngenkathi i-athomu ye-iodine inesibopho se-radiopacity yemidiya yokuqhathanisa, i-organic carrier inesibopho sezinye izakhiwo zayo, njenge-osmolality, i-tonicity, i-hydrophilicity, kanye ne-viscosity. I-organic carrier inesibopho semiphumela eminingi emibi futhi ithole ukunakwa okukhulu kubacwaningi. Ezinye iziguli zisabela enanini elincane lemidiya yokuqhathanisa, kodwa imiphumela eminingi emibi ibangelwa umthwalo omkhulu we-osmotic. Ngakho-ke, eminyakeni embalwa edlule abacwaningi bagxile ekwakheni imidiya yokuqhathanisa enciphisa umthwalo we-osmotic ngemva kokuphathwa kwe-contrast agent.

Kuyini ama-contrast media injectors?

Ama-injector okushintshashintshayo amadivayisi ezokwelapha asetshenziselwa ukufaka imidiya yokushintshashintsha emzimbeni ukuze kuthuthukiswe ukubonakala kwezicubu zezinqubo zezithombe zezokwelapha. (Thatha i-CT double head high pressure injector njengesibonelo, bheka isithombe esingezansi:)

Indlela ubuchwepheshe obusha kakhuluumjovo wokucindezela okuphezulukusiza ekunciphiseni ukuchithwa kwemidiya ephikisanayo ngesikhathi sokufakwa?

1. Izinhlelo Zokujova Ezizenzakalelayo

Izinhlelo zokujova ezizenzakalelayo zingalawula ngokunembile inani lokuqhathanisa elisetshenziswayo, okunikeza amathuba amasha eminyangweni ye-radiology efuna ukwenza lula nokubhala phansi ukusetshenziswa kwayo kwemidiya yokuqhathanisa. Ngokuthuthuka kwezobuchwepheshe,ama-injector anamandla aphezuluziye zashintsha kusukela kuma-injector alula asetshenziswa ngesandla kuya ezinhlelweni ezizenzakalelayo ezingalawuli ngokunembile kuphela inani le-ejenti yemidiya yokungafani esetshenziswayo, kodwa futhi ezisiza ukuqoqwa kwedatha okuzenzakalelayo kanye nemithamo eyenzelwe umuntu ngamunye.

I-LnkMedisungule ama-contrast injector athile ezinqubo zokufaka imithambo yegazi ku-Computed Tomography (CT) kanye ne-Magnetic Resonance Imaging (I-MRI) kanye nezinqubo zangaphakathi kwemithambo yegazi ekungeneleleni kwenhliziyo kanye nangaphandle. Zonke lezi zinhlobo ezine zama-injector zivumela ukujova okuzenzakalelayo. Kukhona neminye imisebenzi ezenzakalelayo eyenzelwe ukwenza lula ukuhamba komsebenzi kwabantu bezempilo nokuthuthukisa ukuphepha, njengokugcwalisa okuzenzakalelayo kanye noku-priming, ukuqhubekela phambili kwe-plunger okuzenzakalelayo kanye nokuhoxisa lapho unamathisela futhi ukhipha amasirinji. Ukunemba kwevolumu kungaba ngaphansi kuka-0.1mL, okuvumela umthamo onembile kakhulu womjovo we-contrast medium.

2. Ama-Injector Angenasipendi

Ama-injector kagesi angenasipendi avele njengesixazululo sokunciphisa imfucuza yemidiya ephikisanayo. Lolu khetho lunikeza izikhungo ithuba lokusebenzisa imidiya ephikisanayo ngempumelelo enkulu ngangokunokwenzeka. NgoMashi 2014, i-Guerbet yethule i-FlowSens, uhlelo lwayo lokujova olungenasipendi olwakhiwe nge-injector ye-softbag kanye nezinto ezilahlwayo ezihlobene nayo, isebenzisa i-injector ye-hydraulic, engenasipendi ukuletha imidiya ephikisanayo; Ama-injector amasha e-Bracco "ahlakaniphile" anika amandla i-syringless angakwazi ukusebenzisa yonke ithonsi le-contrast elifakwe ohlelweni ukuze anciphise kakhulu izindleko. Kuze kube manje, ukwakheka kwawo kuye kwabonisa ukuthi ama-injector kagesi angenasipendi ayelula ukuyisebenzisa futhi esebenza kahle kune-injector yamandla e-double-syringe, kanti imfucuza eyengeziwe nge-CT ethuthukisiwe yokungafani ibonwe kulesi sakamuva. I-injector engenasipendi iphinde yavumela ukonga izindleko ezingaba ngu-$8 ngesiguli ngasinye uma kucatshangelwa izindleko eziphansi kanye nokusebenza okuthuthukisiwe kwamadivayisi.

Njengomhlinzeki,I-LnkMedyenza ukonga izindleko kumakhasimende ayo kube yinto eza kuqala. Sizibophezele ekwakheni imikhiqizo esebenza kahle, ephephile futhi engabizi kakhulu ngokusebenzisa ubuchwepheshe obusha ukuze songe izindleko kumakhasimende ethu.
