ULTRASONIC COATING - COV TXHEEJ TXHEEM TXHEEJ TXHEEM NTAWM TXOJ CAI
Abstract : Txoj kev loj hlob ntawm txoj kev siv tshuaj yeeb-yaj-kiab yuav tsum tsim kom muaj kev sib raug zoo thiab sib koom tes ntawm kev kho mob, cov tshuaj yeeb tshuaj, thiab tshuaj kho kab mob. Qhov no yuav tsum muaj ntau dua thiab ntse tshwj xeeb thiab muaj kev sib tw tshwj xeeb rau txoj kev siv tshuaj yeeb dej caw rau ntau txoj kev siv tshuaj tsuag.
Ntsiab lus: active tshuaj; kev siv tshuaj txau ultrasonic;
Kev siv tshuaj, uas yog raws li cov txheej hauv inert yog ntxiv cov khoom siv bioactive, tsis tsuas yog tuaj yeem txhim kho cov ntshav ntawm lub txheej, tab sis kuj nyob rau hauv qhov kev tawm tsam thaum ntxov (plhuav ntawm lub plab), los ntawm kev tso ntshav siab, thiab qhov zoo Siv cov tshuaj tiv thaiv cov platelet deposition, txo cov mob hyperplasia, thiab cov tshuaj tso tawm los ntawm cov yeeb tshuaj yeeb tshuaj cov khoom phom sij thiab txheej txheej.
Qhov txheej txheem ntawm kev siv tshuaj (los yog cov khoom siv yeeb tshuaj) yog qhov tseem ceeb rau txoj kev vam meej lossis tsis ua tiav ntawm txheej txheej txheej. Yog li ntawd, txoj kev loj hlob ntawm cov txheej txheem kev siv tshuaj yeeb tshuaj tau mus rau hauv viav vias tag nrho. Ntau txheej txheej tau hloov tshiab thiab zoo dua. Txawm li cas los, tseem muaj qee cov kev txwv ntawm cov txheej txheem tam sim no. Muaj kev siv lub cev thiab tshuaj kho rau cov yeeb tshuaj nyob rau ntawm lub qhov cua. Ntawm lawv, kev siv lub cev kom haum yog siv immersion thiab txau, thaum siv cov tshuaj siv los ua cov qauv siv electrochemical rau electroplating. Ua ntej, lub soaking thiab txau ntawm txheej txheej, uniformity ntawm txheej coating tsis yooj yim los tswj lub txheej thiab lub ntom ntawm stent yog kuj unsteady, feem ntau yuav tsum rov qab txheej kom tswj cov txheej nplaum zog thiab thickness Lub ntsiab disadvantage ntawm cov txheej txheem electrochemical txheej txheem yog tias cov khoom siv scaffold tsuas yog tsim los ntawm tus neeg xyuas pib lossis lub semiconductor. Cov txheej txheem nyuab nyuab heev thiab cov khoom loj zuj zus tuaj yeem yooj yim. Cov ntaub ntawv siv yeeb tshuaj feem ntau yuav tsum tau hloov tshuaj.
Lub Lag Luam los kov yeej cov kev txwv ntawm cov txheej txheem uas twb muaj lawm cov kev tshawb nrhiav thiab kev tsim kho ultrasonic kho mob cov khoom, ultrasonic txheej txoj kev siv cov hluav taws xob hauv oscillation, ua rau cov neeg muaj zog ua hluav taws xob uas muaj hluav taws xob ua ultrasound. Ultrasonic cavitation tshwm sim thaum nws propagates hauv dej. Ultrasound kev kho mob siv cov qhov dej tawg uas tshwm sim ntawm dej thiab huab cua mus rau cov dej nyob ib ncig ntawm lub qhov ntawm 10-90 micron particles, uas yog txau rau daim nplua coatings. Lub ntsiab zoo ntawm ultrasonic kho mob khoom tsim los ntawm CHI-Fei Ultrasonic yog raws li nram no: cov txheej txheem yog qhov yooj yim thiab yooj yim rau kev lag luam tsis muaj cov khoom siv nyuab; cov tshuaj tso tawm yog yooj yim dua los tswj; qhov loj-scale qhuav yog yooj yim; thiab cov khoom siv scaffold tuaj yeem siv tau rau cov hlau uas tsis yog hlau-hlau uas tau ua stent; lo thiab stent ntog adsorption kaw, tsis yooj yim rau poob tawm; Txheej saum npoo ntau dua, qhov chaw sim tau me ntsis ntawm cov txheej; Tsis tas yuav rov qab ua cov txheej; Kev kawm siab ntawm automation.
