Kutheni Kubalulekile Ukusebenzisa I-High Pressure Injector Ukujova I-Contrast Media Ngexesha Lovavanyo Lwe-CT Oluphuculweyo?

Ngexesha lovavanyo lwe-CT oluphuculweyo, umqhubi usebenzisa i-injector enoxinzelelo oluphezulu ukufaka ngokukhawuleza i-contrast agent kwimithambo yegazi, ukuze amalungu, izilonda kunye nemithambo yegazi ekufuneka ijongwe zibonakale ngokucacileyo. I-injector enoxinzelelo oluphezulu ingafaka ngokukhawuleza nangokuchanekileyo inani elaneleyo le-contrast media enoxinzelelo oluphezulu kwimithambo yegazi yomzimba womntu, ithintele i-contrast media ukuba inganciphisi ngokukhawuleza emva kokuba ifakwe emzimbeni womntu. Isantya sihlala simiselwa ngokwendawo yovavanyo. Umzekelo, kuvavanyo lwesibindi oluphuculweyo, isantya sokufaka sigcinwa kuluhlu lwe-3.0 - 3.5 ml/s. Nangona i-injector enoxinzelelo oluphezulu ifaka ngokukhawuleza, lo gama nje imithambo yegazi yomntu inokuqina okuhle, izinga lokufaka likhuselekile. Idosi ye-contrast agent esetyenziswa kwi-CT scan ephuculweyo imalunga ne-1000 yevolumu yegazi lomntu, engayi kubangela ukuguquguquka okukhulu kumthamo wegazi lomntu.

Xa i-contrast media ifakwa kwimithambo yomntu, umntu uya kuziva enomkhuhlane wendawo okanye kwane-systemic fever. Oku kungenxa yokuba i-contrast agent yinto yekhemikhali eneempawu eziphezulu ze-osmotic. Xa i-injector enoxinzelelo oluphezulu ifakwa kwimithambo ngesantya esiphezulu, udonga lwemithambo yegazi luya kuvuselelwa kwaye umntu uya kuva iintlungu zemithambo yegazi. Ingasebenza ngokuthe ngqo kwimisipha egudileyo yemithambo yegazi, ibangele ukwanda kwemithambo yegazi yendawo kwaye ivelise ubushushu kunye nokungonwabi. Oku ngokwenene yimpendulo ye-contrast agent engeyi kulimaza umzimba womntu. Iya kubuyela kwimeko yesiqhelo ngokukhawuleza emva kokuphucula. Ke ngoko, akukho mfuneko yokoyika okanye ukungaqondi kakuhle ukuba umkhuhlane wendawo okanye wenkqubo uyenzeka xa i-contrast agent ifakwa.

I-LnkMed igxile kushishino lwe-angiography kwaye ngumenzi oqeqeshiweyo obonelela ngezisombululo zomfanekiso.I-CT single,Intloko ezimbini ze-CT , I-MRIkwayeI-DSAIi-injectors zoxinzelelo oluphezulu zisetyenziswa kakhulu kwizibhedlele ezinkulu ekhaya nakwamanye amazwe.
Sijonge ukwenza iimveliso zethu zisebenze ngakumbi ukuhlangabezana neemfuno zakho ezijoliswe kwisigulane kwaye ziqatshelwe ziiarhente zonyango kwihlabathi liphela.
