Iindlela zamva nje zokujova nge-High Pressure Injectors zinceda ekunciphiseni inkunkuma engafaniyo nezinye

Itekhnoloji entsha ye-injector ye CT, I-MRIkwayeI-Angiographyiinkqubo zinceda ekunciphiseni umthamo kwaye zirekhoda ngokuzenzekelayo umahluko osetyenzisiweyo kwirekhodi yesigulana.

Kutshanje, izibhedlele ezininzi ziye zaphumelela ekunciphiseni iindleko ngokusebenzisa ii-contrast injectors eziyilwe ngobuchwepheshe obuphambili ekunciphiseni inkunkuma ye-contrast kunye nokuqokelelwa kwedatha ngokuzenzekelayo kwedosi efunyanwa sisigulana.

Okokuqala, masithathe imizuzu embalwa sifunde nge-contrast media.

Yintoni imidiya echaseneyo?

I-contrast media yinto efakwa emzimbeni ukuze yomeleze umahluko phakathi kwezicubu zomzimba kwimifanekiso. I-contrast medium efanelekileyo kufuneka ifumane uxinaniso oluphezulu kakhulu kwizicubu ngaphandle kokuvelisa naziphi na iziphumo ezibi.

Iintlobo zeContrast Media

I-Iodine, iminerali ekhutshwa kakhulu emhlabeni, edwaleni nakwi-brine, isetyenziswa kakhulu kwi-contrast media kwi-CT nakwi-X-ray imaging. I-Lodinated contrast media zezona arhente zisetyenziswa kakhulu, apho i-CT ifuna ubungakanani obukhulu ngokubanzi. Zonke ii-contrast agents ezisetyenziswayo ngoku zisekelwe kwi-triiodinated benzene ring. Ngelixa i-athomu ye-iodine inoxanduva lwe-radiopacity ye-contrast media, i-organic carrier inoxanduva lwezinye iimpawu zayo, ezifana ne-osmolality, i-tonicity, i-hydrophilicity, kunye ne-viscosity. I-organic carrier inoxanduva lweziphumo ezininzi ezimbi kwaye ifumene ingqwalasela eninzi kubaphandi. Ezinye izigulana zisabela kwi-contrast media encinci, kodwa uninzi lweziphumo ezimbi zibangelwa ngumthwalo omkhulu we-osmotic. Ke ngoko, kwiminyaka embalwa edlulileyo abaphandi bagxile ekuphuhliseni i-contrast media enciphisa umthwalo we-osmotic emva kokusetyenziswa kwe-contrast agent.

Yintoni ii-contrast media injectors?

Ii-injectors ze-Contrast zizixhobo zonyango ezisetyenziselwa ukufaka i-contrast media emzimbeni ukuphucula ukubonakala kwezicubu kwiinkqubo zemifanekiso yezonyango. (Thatha i-CT double head high pressure injector njengomzekelo, jonga umfanekiso ongezantsi:)

Indlela iteknoloji entsha esetyenziswa ngayoinjector yoxinzelelo oluphezulukunceda ukunciphisa inkunkuma ye-contrast media ngexesha lokufaka inaliti?

1. Iinkqubo zokujova ezizenzekelayo

Iinkqubo zokujova ezizenzekelayo zinokulawula ngokuchanekileyo ubungakanani bomahluko osetyenzisiweyo, nto leyo enika amathuba amatsha kumasebe e-radiology afuna ukwenza lula nokubhala phantsi ukusetyenziswa kwawo kwemidiya yomahluko. Ngokuhambela phambili kwetekhnoloji,ii-injectors zoxinzelelo oluphezuluziye zavela kwii-injectors ezilula ezenziwe ngesandla ukuya kwiinkqubo ezizenzekelayo ezingalawuli ngokuchanekileyo kuphela ubungakanani be-agent ye-contrast media esetyenzisiweyo, kodwa zikwanceda ekuqokeleleni idatha ngokuzenzekelayo kunye needosi ezenzelwe umntu ngamnye kwisigulana ngasinye.

I-LnkMeduphuhlise ii-contrast injectors ezithile kwiinkqubo ze-intravenous kwi-Computed Tomography (CTkunye neMagnetic Resonance Imaging (I-MRI) kunye neenkqubo zangaphakathi kwemithambo yegazi kwi-cardiac and peripheral intervention. Zonke ezi ntlobo zine zee-injectors zivumela i-automatic injection. Kukwakho neminye imisebenzi ezenzekelayo eyenzelwe ukwenza lula umsebenzi wabantu bezempilo kunye nokuphucula ukhuseleko, njengokuzalisa ngokuzenzekelayo kunye ne-priming, i-automatic plunger advance kunye ne-retract xa uncamathisela kwaye ukhupha iisirinji. Ukuchaneka komthamo kunokwehla ukuya kwi-0.1mL, kuvumela idosi echanekileyo ngakumbi ye-contrast medium injection.

2. Ii-Injectors ezingenasirinji

Ii-injectors zamandla ezingenasyringe ziye zavela njengesisombululo sokunciphisa inkunkuma ye-contrast media. Olu khetho lunika izibonelelo ithuba lokusebenzisa i-contrast media ngokufanelekileyo kangangoko. NgoMatshi 2014, iGuerbet yaqalisa iFlowSens, inkqubo yayo yokufaka i-syringe-free equlunqwe yi-softbag injector kunye nezinto ezilahlwayo ezinxulumene nayo, isebenzisa i-hydraulic, i-syringe-free injector ukuhambisa i-contrast media；Iinjectors ezintsha zeBracco ze-"smart" Empower syringless ziyakwazi ukusebenzisa yonke ithontsi le-contrast efakwe kwinkqubo ukuze zifikelele kwinqanaba eliphezulu. Okwangoku, uyilo lwazo luye lwabonisa ukuba ii-injectors zamandla ezingenasyringe zazilula ukuyisebenzisa kwaye zisebenza kakuhle kune-injector yamandla ene-dual-syringe, kwaye inkunkuma engaphezulu kwi-CT nganye ephuculweyo ye-contrast ibonwe kwi-last. I-injector engenasyringe ikwavumele ukonga iindleko ezimalunga ne-$8 ngesigulana xa kucingwa ngexabiso eliphantsi kunye nokusebenza okuphuculweyo kwezixhobo.

Njengomthengisi,I-LnkMedyenza ukonga iindleko kubathengi bayo kube yeyona nto iphambili. Sizibophelele ekuyileni iimveliso ezisebenzayo, ezikhuselekileyo nezingabizi kakhulu ngokusebenzisa ubugcisa obutsha ukuze songe iindleko kubathengi bethu.
