Zochitika Zaposachedwa za Ma Injector Othamanga Kwambiri Zimathandiza Kuchepetsa Zinyalala Zosiyanasiyana

Ukadaulo watsopano wa injector wa CT, MRIndiAngiographyMachitidwewa amathandiza kuchepetsa mlingo ndipo amalemba okha kusiyana komwe kumagwiritsidwa ntchito pa zolemba za wodwala.

Posachedwapa, zipatala zambiri zachepetsa ndalama pogwiritsa ntchito majekeseni oyezera kusiyanitsa mitundu omwe adapangidwa ndi ukadaulo wapamwamba pochepetsa zinyalala za kusiyanitsa mitundu komanso kusonkhanitsa deta yokha ya mlingo womwe wodwala amalandira.

Choyamba, tiyeni titenge mphindi zingapo kuti tiphunzire za zinthu zosiyanitsa mitundu.

Kodi zinthu zosiyanitsa mitundu n'chiyani??

Chophimba chosiyanitsa ndi zinthu ndi chinthu chomwe chimalowetsedwa m'thupi kuti chiwonjezere kusiyana pakati pa minofu ya thupi pazithunzi. Chophimba chosiyanitsa ndi zinthu chabwino kwambiri chiyenera kukhala ndi kuchuluka kwakukulu m'minofu popanda kubweretsa zotsatirapo zoyipa.

Mitundu ya Zosiyanasiyana Zosiyanasiyana

Iodini, mchere womwe umachokera ku dothi, miyala ndi madzi amchere, umagwiritsidwa ntchito kwambiri mu zinthu zotsutsana pa CT ndi X-ray. Zinthu zotsutsana ndi lodinated ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri, ndipo CT imafuna kuchuluka kwakukulu. Zinthu zonse zotsutsana zomwe zimagwiritsidwa ntchito pakali pano za computed tomography (CT) zimachokera ku triiodinated benzene ring. Pomwe atomu ya ayodini imayang'anira kuwala kwa zinthu zotsutsana, chinthu chonyamula zinthu zachilengedwe chimayang'anira zinthu zina, monga osmolality, tonicity, hydrophilicity, ndi viscosity. Chinthu chonyamula zinthu zachilengedwe chimayang'anira kwambiri zotsatirapo zake zoyipa ndipo chalandira chidwi chachikulu kuchokera kwa ofufuza. Odwala ena amachitapo kanthu pang'ono pa zinthu zotsutsana, koma zotsatira zake zambiri zimayambitsidwa ndi katundu waukulu wa osmotic. Chifukwa chake, m'zaka makumi angapo zapitazi ofufuza akhala akuyang'ana kwambiri pakupanga zinthu zotsutsana zomwe zimachepetsa katundu wa osmotic pambuyo popereka zinthu zotsutsana.

Kodi ma injector a contrast media ndi chiyani?

Majekeseni osiyanitsa mitundu ndi zipangizo zachipatala zomwe zimagwiritsidwa ntchito poika zinthu zosiyanitsa mitundu m'thupi kuti ziwonekere bwino minofu ya thupi pogwiritsa ntchito zithunzi zachipatala. (Tengani jekeseni ya CT double head high pressure mwachitsanzo, onani chithunzi chili pansipa:)

Momwe ukadaulo waposachedwa kwambiri mujekeseni ya kuthamanga kwambirithandizani kuchepetsa kutayika kwa zinthu zosiyanitsa pakati pa jekeseni?

1. Makina Opangira Injector Okha

Makina ojambulira okha amatha kuwongolera molondola kuchuluka kwa kusiyana komwe kumagwiritsidwa ntchito, zomwe zimapereka mwayi watsopano kwa madipatimenti a radiology omwe akufuna kusintha ndikulemba momwe amagwiritsira ntchito zosiyanitsa. Ndi kupita patsogolo kwaukadaulo,majakisoni othamanga kwambiriZasintha kuchoka pa ma injector osavuta opangidwa ndi manja kupita ku machitidwe odziyimira okha omwe samangoyang'anira kuchuluka kwa chosinthira chosiyanitsa chomwe chimagwiritsidwa ntchito, komanso amathandizira kusonkhanitsa deta yodziyimira payokha komanso milingo yosiyana kwa wodwala aliyense payekha.

LnkMedyapanga majekeseni osiyanitsa mitundu kuti agwiritsidwe ntchito m'mitsempha mu Computed Tomography (CT) ndi Magnetic Resonance Imaging (MRI) komanso njira zochizira matenda a mtima ndi ziwalo zina. Mitundu yonseyi inayi ya majekiseni imalola jakisoni wodzipangira okha. Palinso ntchito zina zodzipangira zokha zomwe zimapangidwa kuti zichepetse ntchito ya anthu azaumoyo ndikuwonjezera chitetezo, monga kudzaza ndi kuyika ma primer, kupititsa patsogolo ndi kubweza ma plunger odzipangira okha polumikiza ndi kuchotsa ma syringe. Kulondola kwa voliyumu kumatha kutsika kufika pa 0.1mL, zomwe zimathandiza kuti jakisoni wosiyanitsa azitha kuperekedwa molondola.

2. Majekeseni Opanda Sirinji

Ma injector amphamvu opanda syringe aonekera ngati njira yothetsera kutayika kwa zinthu zotsutsana. Njirayi imapatsa malo mwayi wogwiritsa ntchito zinthu zotsutsana moyenera momwe angathere. Mu Marichi 2014, Guerbet idakhazikitsa FlowSens, njira yake yojambulira yopanda syringe yopangidwa ndi injector ya softbag ndi zinthu zina zotayidwa, pogwiritsa ntchito injector ya hydraulic, yopanda syringe kuti ipereke zinthu zotsutsana; Ma injector atsopano a Bracco a "smart" Empower syringless amatha kugwiritsa ntchito dontho lililonse la zinthu zotsutsana zomwe zalowetsedwa mu dongosololi kuti azigwiritsa ntchito ndalama zambiri. Pakadali pano, kapangidwe kawo katsimikizira kuti ma injector amphamvu opanda syringe anali osavuta kugwiritsa ntchito komanso ogwira ntchito bwino kuposa injector yamagetsi ya dual-syringe, ndipo zinyalala zambiri pa CT yowonjezereka ya contrast zimawonedwa kwa wodwalayo. Injector yopanda syringe idalolanso kusunga ndalama pafupifupi $8 pa wodwala aliyense poganizira mtengo wotsika komanso magwiridwe antchito abwino a zida.

Monga wogulitsa,LnkMedzimapangitsa kuti makasitomala athu asamawononge ndalama zambiri. Tadzipereka kupanga zinthu zothandiza, zotetezeka komanso zotsika mtengo kudzera muukadaulo wamakono kuti tisunge ndalama kwa makasitomala athu.
