Cov Qauv Cuam Tshuam Elastic Tsim Polyvinyl Cawv Hluav Taws Xob Hluav Taws Xob

Pos us micrhpheres yog constressible hydrogel microspheres nrog cov duab tsis tu ncua, du los ua cov tshuaj kho mob ntawm polyvinyl cawv (pva) cov ntaub ntawv. Purnolic jearcheles muaj macromer muab tau los ntawm polyvinyl cawv (PVA), thiab yog-resigable, thiab muaj nyob hauv ntau yam ntawm cov ntau thiab tsawg. Kev tshuaj tiv thaiv yog 0.9% sodium vloride tov. Cov ntsiab lus dej ntawm tag nrho polymerized micymerized yog 91% ~ 94%. Jearchares tuaj yeem ua siab ntev compression ntawm 30%.
Cov embum siv jecholm
Cov emburbic tsom iav yog npaj los siv rau cov embolization ntawm cov qog ntshav (avps) thiab hypervascular qog, suav nrog uterine fibroids. Los thaiv cov ntshav rau lub hom phiaj, cov qog lossis malformation yog stinved ntawm cov as-ham thiab shrinks loj.
Cov embumic jookpheres tuaj yeem xa los ntawm cov microcatheters cov raug nyob hauv 1.7- 4 FL ntau. Thaum siv lub sijhawm siv, cov embolic lub micropheres tau sib xyaw nrog cov neeg saib xyuas tus neeg uas tsis muaj kev daws teeb meem. Cov embum siv jearchpheres yog npaj rau ib qho kev siv thiab tau muab cov khoom tsis huv thiab tsis muaj pyrogenic. Cov cuab yeej teeb tsa ntawm embolic microphere tau piav qhia hauv lub rooj 1 thiab rooj 2 hauv qab no.
Ntawm ntau qhov loj me me ntawm embolic micrpheres, qhov loj me uas tuaj yeem siv rau uterine fibroid embolization yog 500-700μm, 700-900μm thiab 900-1200μm.
