Daim Ntawv Thov Ntawm Ultrasonic Atomization hauv Balloon Spraying

Tshuaj-eluting balloons (DEBs) thiab functionally coated balloons are core devices in interventional vascular therapy. Lub uniformity ntawm lawv cov coatings, qhov tseeb ntawm cov tshuaj loading, thiab lawv cov morphology nto ncaj qha txiav txim qhov zoo ntawm cov tshuaj thiab kev nyab xeeb. Ultrasonic atomization txheej, nrog nws qhov zoo ntawm qhov tsis tshua muaj siab thiab ua siab mos siab, tsis tu ncua kev faib tawm, kev tswj tau ntau npaum li cas, thiab kev siv cov khoom siv siab, tau dhau los ua cov txheej txheem tseem ceeb rau cov txheej txheem zais pa thiab siv dav hauv kev npaj cov tshuaj -eluting, anti-proliferative, thiab lubricating coatings rau coronary, peripheral thiab peripheral. Kab lus no systematically elucidates tus nqi engineering ntawm ultrasonic atomization nyob rau hauv balloon txheej, npog nws cov txheej txheem kev, core zoo, raug txheej txheem, daim ntawv thov scenarios, thiab kev loj hlob tiam sis.

Ultrasonic Atomization Txau Txoj Cai

Kev hloov hluav taws xob:Lub tshuab hluav taws xob ultrasonic hloov hluav taws xob rau hauv siab - zaus txhua yam kev co (feem ntau 120-180 kHz), uas yog ces xa mus rau atomization nto ntawm lub nozzle;

Ua kua Atomization:Cov ntaub ntawv ua kua tsim cov kab mob capillary ntawm lub atomization nto, uas tau tawg mus rau hauv monodisperse micron - cov tee me me (feem ntau 10-20 μm);

Tsawg-Nyob rau hauv siab:Nrog kev pab los ntawm ib tug tsis muaj zog airflow phau ntawv qhia, cov tee dej yog deposited uniformly thiab nyob rau hauv qis ceev ntawm qhov chaw ntawm lub qhov muag teev, qhuav los ua ib tug zaj duab xis;

Precise Control:Kaw -Txoj kev tswj cov txheej tuab thiab qhov ntom ntom ntawm thaj chaw yog ua tiav los ntawm zaus, lub zog, ntws tus nqi, kev sib hloov ceev, thiab scanning ceev.

Core Technological Advantages

Cov Txheej Txheem Zoo Tshaj Plaws:Qhov me me me me me faib ua kom muaj kev sib koom ua ke ntawm qhov chaw nkhaus thiab qhov muag plooj, txo qis qhov ua yuam kev thiab tiv thaiv kev nyob hauv cheeb tsam tshaj - lossis hauv qab - kev tswj hwm tshuaj.

Tsis tshua muaj siab thiab maj mam ntawm substrate:Tsis muaj qhov siab -siab airflow cuam tshuam tiv thaiv balloon deformation, wrinkling, los yog stretching, kom ntseeg tau tias catheter loj thiab cov qauv precision.

Kev Siv Tshuaj Zoo Tshaj Plaws Zoo Tshaj Plaws:Tsis muaj kev tawg loj heev; Kev siv tshuaj mus txog ntau dua 85%, deb tshaj li cov txheej txheem ib txwm muaj, txo cov nqi ntawm cov tshuaj kim heev.

Precise thiab Controllable Thickness:Txhawb nano- rau micron- theem txheej; customizable ib leeg -txheej / ntau- txheej txheej gradient txheej raws li kev ruaj ntseg - tso tawm thiab tswj - tso tawm cov cai.

Stable Txheej Zoo:Txo cov pinholes, sagging, txiv kab ntxwv tev, thiab crystallization abnormalities, txhim kho biocompatibility thiab kev kho mob tso tawm sib xws.

Wide Compatibility: Tau tshaj cov tshuaj xws li paclitaxel, rapamycin, thiab sirolimus, nrog rau ntau yam kev kho mob polymers thiab hydrophilic txheej txheej txheem.
