Tekinoroji nyowani yejekiseni ye CT, MRIuyeAngiographymasisitimu anobatsira kuderedza dose uye otomatiki anorekodha musiyano unoshandiswa kune rekodha yemurwere.
Munguva ichangopfuura, zvipatara zvakawanda zvakabudirira kuderedza mari nekushandisa majekiseni ekusiyanisa akagadzirwa nehunyanzvi hwepamusoro mukuderedza kuraswa kwekusiyanisa uye kuunganidza data otomatiki kune dosi inotambirwa nemurwere.
Chekutanga, ngatitorei maminetsi akati wandei kuti tidzidze nezvekusiyanisa media.
Chii chinonzi kusiyana media?
Contrast media chinhu chinopinzwa mumuviri kuti chiwedzere mutsauko pakati pematishu emuviri pamifananidzo. Iyo yakanakira yekusiyanisa svikiro inofanirwa kuwana yakanyanya kukwirisa mumatishu pasina kuburitsa chero yakaipa mhedzisiro.
Mhando dzeKusiyanisa Media
Iodine, chicherwa chinotorwa zvakanyanya kubva muvhu, dombo uye brine, inowanzoshandiswa mukusiyanisa midhiya kune ese CT uye X-ray imaging. Lodinated different media ndiyo inonyanya kushandiswa, neCT inoda huwandu hukuru hwese. Yese parizvino inoshandiswa computed tomography (CT) kusiyanisa maajenti anobva pane triiodinated benzene ring. Nepo iyo atomu yeiodine ine basa reiyo radiopacity yekusiyanisa midhiya, iyo organic carrier ine basa rezvimwe zvinhu zvayo, senge osmolality, tonicity, hydrophilicity, uye viscosity. Iyo organic carrier ndiyo inokonzeresa yakawanda yeakaipa mhedzisiro uye yakagamuchira kutariswa kwakawanda kubva kune vaongorori. Vamwe varwere vanoita kune zvidiki zvekusiyanisa midhiya, asi yakawanda yeakaipa mhedzisiro inopindirana nehombe osmotic mutoro. Nekudaro, mumakumi mashoma emakore apfuura vaongorori vakatarisa mukugadzira midhiya inosiyanisa iyo inoderedza iyo osmotic mutoro mushure mekusiyanisa mumiriri kutonga.
Chii chinonzi majekiseni ekusiyanisa media?
Majekiseni ekusiyana (Contrast injectors) zvishandiso zvekurapa zvinoshandiswa kubaya majekiseni ekusiyanisa kupinda mumuviri kuti awedzere kuoneka kwematishu ekurapwa. (Tora CT double head high pressure injector semuenzaniso, ona mufananidzo uri pazasi:)
Iyo tekinoroji nyowani mukatihigh pressure injectionbatsira kuderedza marara ekusiyanisa media panguva yejekiseni?
1.Automated Injector Systems
Otomatiki majekiseni masisitimu anogona kunyatso kudzora huwandu hwekusiyanisa hunoshandiswa, hunopa mikana mitsva yemadhipatimendi eradiology anotarisa kukwenenzvera uye kunyora mutsauko wavo wekushandiswa kwenhau. Nekufambira mberi kwetekinoroji, iyohigh pressure injectorsdzakashanduka kubva kune akareruka majekiseni echinyorwa kuenda kune otomatiki masisitimu ayo asingangotarisiri chaizvo huwandu hweanosiyanisa media agent inoshandiswa, asi zvakare kufambisa otomatiki kuunganidza data uye madosi emunhu kune mumwe nemumwe murwere.
LnkMedyakagadzira majekiseni akasiyana-siyana ekugadzirisa intravenous muComputed Tomography (CT) uye Magnetic Resonance Imaging (MRI) uye nokuda kwemaitiro emukati mukati memwoyo uye peripheral kupindira. Ese aya marudzi mana emajekiseni anobvumira otomatiki jekiseni. Kune zvakare mamwe mabasa otomatiki akagadzirirwa kurerutsa mafambiro ehutano hwevanhu uye kuwedzera kuchengetedzeka, senge otomatiki kuzadza uye priming, otomatiki plunger kumberi uye kudzoreredza kana uchibatanidza nekubvisa masirinji. Iyo chaiyo vhoriyamu inogona kudzika kusvika ku0.1mL, inogonesa yakanyatso dhamu yejekiseni repakati.
2. Syringeless Majekiseni
Siringeless magetsi majekiseni abuda semhinduro yekudzikisa mutsauko kutambisa media. Iyi sarudzo inopa zvivakwa mukana wekushandisa mutsara media zvinobudirira sezvinobvira. Muna Kurume 2014, Guerbet yakatanga FlowSens, jekiseni rayo risina jekiseni rinoumbwa nejekiseni rebag rakapfava uye rinoraswa rinoraswa, richishandisa hydraulic, jekiseni-isina jekiseni kuendesa midhiya yakasiyana; yekusiyanisa yakatakurwa muhurongwa hwehupfumi hwepamusoro. Kusvika pari zvino, dhizaini yavo yaratidza kuti jekiseni remagetsi risina jekiseni raishandisa nyore kushandisa uye kushanda zvakanaka kupfuura jekiseni remagetsi rejekiseni, riine marara akawanda pakusiyanisa-yakakwidziridzwa CT inocherechedzwa kune yekupedzisira. Jekiseni risina jekiseni rakabvumirawo kuchengetedza mari inosvika madhora masere pamurwere kana tichifunga nezvemutengo wakaderera uye nekuvandudza kushanda kwemidziyo.
Semutengesi,LnkMedinoita kuchengetedza mari kune vatengi vayo chinhu chekutanga. Isu takazvipira kugadzira zvigadzirwa zvinoshanda, zvakachengeteka uye zvehupfumi kuburikidza nehunyanzvi hwekuvandudza tekinoroji kuchengetedza mutengo kune vatengi vedu.
