Ultrasonic Spray txheej tshuab siv hauv kev lag luam kho mob

Nyob rau hauv xyoo tas los no, ultrasonic atomization spraying tshuab tau ua tiav kev nkag mus thoob plaws thiab hauv - daim ntawv thov tob hauv kev lag luam kho mob vim nws qhov tshwj xeeb thev naus laus zis. Cov thev naus laus zis tshiab no, uas sib koom ua ke ultrasonic vibration thiab precision spraying, tsis tau tsuas yog tawg los ntawm ntau qhov kev txwv ntawm cov txheej txheem kho mob ib txwm muaj tab sis kuj tau qhib txoj kev txhim kho tshiab hauv cov chaw tseem ceeb xws li kev xa tshuaj, kev tsim khoom siv kho mob, thiab cov ntaub so ntswg engineering, txhaj tshuaj muaj zog rau hauv kev txhim kho thev naus laus zis thiab kev txhim kho kev lag luam zoo.

Lub hauv paus ntsiab lus tseem ceeb ntawm ultrasonic atomization spraying tshuab yog nyob rau hauv kev siv siab - zaus ultrasonic vibration (feem ntau nyob rau hauv thaj tsam ntawm 40kHz-100kHz) los tsim cov dej tsis sib xws ntawm cov khoom ua kua ntawm micron lossis txawm nanometer nplai. Cov tee dej no yog tom qab ntawd txau mus rau lub hom phiaj ntawm qhov chaw los ntawm kev tswj hwm huab cua. Tsis zoo li kev siv tshuaj tua kab mob thiab tshuaj tua kab mob, cov cuab yeej no tsis tas yuav muaj kev pab roj siab siab -. Hloov chaw, nws hloov hluav taws xob hluav taws xob mus rau hauv lub tshuab hluav taws xob los ntawm lub tshuab hluav taws xob, ua rau cov kua ua rau lub khob hliav qab- zoo li huab cua nyob rau saum npoo ntawm ultrasonic transducer. Kev faib tawm me me ntawm cov tee dej yog qhov sib xws, thiab cov txheej txheem txau yog cuam tshuam -dawb thiab txaws{13}}dawb, ua tiav qhov tseeb ntawm thaj chaw lub hom phiaj. Nws cov txheej txheem thev naus laus zis tseem ceeb yog nyob rau hauv qhov hloov kho qhov me me (yuav kho tau hauv 1-100 micrometer ntau), siab -kev tswj cov txheej tuab (yuam tsis tshaj ± 1%), thiab cov yam ntxwv tsis zoo uas tshwm sim los ntawm kev tsis sib cuag nrog tshuaj tsuag. Cov txiaj ntsig thev naus laus zis no tau tsim lub hauv paus ruaj khov rau nws daim ntawv thov hauv kev kho mob. Hauv daim ntawv thov kev kho mob, ultrasonic atomization spraying tshuab qhia muaj zog adaptability thiab innovation. Nyob rau hauv lub tshav pob ntawm kev xa tshuaj, cov cuab yeej no tau ua tiav kev hloov pauv hauv kev kho cov kab mob ua pa.

Cov tshuaj pleev ib ce raug kev txom nyem los ntawm qhov tsis sib xws ntawm cov tee me me thiab kev siv tshuaj tsawg, thaum ultrasonic atomization txau cov cuab yeej tuaj yeem atomize cov tshuaj daws rau hauv ultrafine tee ntawm 1-5 micrometers, uas tuaj yeem nkag mus ncaj qha rau hauv alveoli ntawm lub ntsws, txhim kho kev nqus tshuaj zoo. Piv txwv li, rau cov neeg mob uas muaj mob hawb pob thiab mob ntsws obstructive pulmonary disease (COPD), portable nebulizers siv ultrasonic atomization spraying tshuab tau precisely xa cov tshuaj xws li glucocorticoids rau qhov txhab, nce kev siv tshuaj ntau dua 30% piv rau cov khoom siv tshuaj, thiab txo cov kev mob tshwm sim ntawm kev siv tshuaj.

Hauv kev tsim khoom siv kho mob, ultrasonic atomization txau tshuab tau dhau los ua cov txheej txheem tseem ceeb hauv kev npaj cov khoom tseem ceeb rau siab -kawg cov cuab yeej kho mob. Implantable kho mob cov cuab yeej xws li dag lub plawv li qub thiab vascular stents yuav tsum tau biocompatible coatings kom txo tau lub cev tsis muaj zog thiab txhim kho implantation ua tau zoo. Cov txheej txheem txheej txheem txheej txheem raug kev txom nyem los ntawm cov txheej txheem tsis sib xws thiab cov adhesion tsis zoo, thaum ultrasonic atomization txau tshuab tuaj yeem ua cov txheej txheem biomaterials xws li polylactic acid thiab chitosan rau saum npoo ntawm cov cuab yeej, tsim cov txheej txheem ua haujlwm nrog cov tuab tswj tau (5-50 micrometers) thiab muaj zog adhesion. Lub tuam txhab kho mob siv cov thev naus laus zis no tau tsim cov tshuaj eluting stents nrog txheej txheej kev ua yuam kev tswj tsis pub dhau 5%, cov tshuaj tso tawm ruaj khov, thiab 15% siab dua qhov chaw kho mob implantation zoo dua piv rau cov khoom siv. Cov khoom no tau txais NMPA ntawv pov thawj thiab muaj nyob rau hauv ntau lawm.

Tsis tas li ntawd, nyob rau hauv thaj chaw ntawm cov ntaub so ntswg engineering thiab cov tshuaj regenerative, ultrasonic atomization spraying tshuab muab cov kev daws teeb meem tshiab rau kev hloov kho ntawm peb -dimensional biological scaffolds. Cov thev naus laus zis no tuaj yeem txau cov tshuaj bioactive xws li kev loj hlob thiab cytokines rau saum npoo ntawm cov ntaub ntawv scaffold, tsim kom muaj biomimetic microenvironment uas txhawb nqa cell adhesion, proliferation, thiab sib txawv. Kev tshawb fawb cov ntaub ntawv qhia tau hais tias cov pob txha cov ntaub so ntswg engineering scaffolds kho nrog ultrasonic atomization spraying pom ib tug 40% nce nyob rau hauv cell adhesion thiab ib tug 30% acceleration nyob rau hauv vivo osteogenic tus nqi piv rau untreated scaffolds, muab ib tug tshiab kev daws teeb meem rau kev kho mob cov teeb meem xws li cov pob txha tsis xws luag.

Piv rau cov txheej txheem kho mob ib txwm muaj, ultrasonic atomization spraying tshuab muaj ntau qhov zoo: Ua ntej, nws yog qhov tseeb thiab tswj tau, tso cai rau kev hloov pauv ntawm cov tee me me, tshuaj tsuag thickness, thiab kev pab them nqi, ua tau raws li cov kev cai nruj nruj ntawm kev kho mob. Qhov thib ob, nws yog ib qho yooj yim thiab tsis yog - puas tsuaj, nrog rau tsis yog - tiv tauj cov tshuaj tsuag thiab cov yam ntxwv ntawm kev vibration qis kom tsis txhob muaj kev puas tsuaj rau cov tshuaj bioactive (xws li tshuaj thiab cov hlwb), ua kom muaj kev ruaj ntseg ntawm cov khoom siv kho mob. Thib peb, nws muaj txiaj ntsig zoo thiab tus phooj ywg zoo ib puag ncig, ua tiav kev siv cov khoom siv ntau dua 85% thaum lub sij hawm txau, txuag 30% -50% ntawm raw cov ntaub ntawv piv rau cov txheej txheem ib txwm siv, thiab tshem tawm cov organic hnyav evaporation, ua raws li cov qauv tsim ntsuab hauv kev kho mob kev lag luam. Plaub, nws yog qhov sib xws heev, hloov mus rau ntau hom khoom siv kho mob, suav nrog dej-raws li, roj-raws li, thiab cov khoom siv bioactive, ua rau nws haum rau ntau yam kev siv. Cov kws tshaj lij hauv kev lag luam taw qhia tias daim ntawv thov ntawm ultrasonic atomization txau tshuab hauv kev kho mob tsis tau tsuas yog txhawb kev txhim kho cov khoom siv kho mob thiab txhim kho cov teebmeem kev kho mob, tab sis tseem ua kom cov txheej txheem hauv cheeb tsam ntawm cov khoom siv kho mob siab.

Nrog rau kev siv thev naus laus zis txuas ntxiv thiab maj mam txo tus nqi, cov thev naus laus zis no xav kom ua tiav hauv ntau qhov chaw tshwj xeeb xws li kev xa tshuaj tiv thaiv, xa tshuaj tawv nqaij, thiab kho hniav. Nyob rau hauv lub neej yav tom ntej, nrog rau kev sib sib zog nqus technologies xws li kev txawj ntse txawj ntse thiab Internet ntawm tej yam nrog ultrasonic atomization spraying tshuab, tiag tiag - lub sij hawm optimization thiab tej thaj chaw deb saib xyuas ntawm cov txheej txheem tsis yuav tsum tau paub ntxiv, muab muaj zog technical support rau txoj kev loj hlob ntawm tus kheej thiab precision tshuaj. Nws tau kwv yees tias lub ntiaj teb kev lag luam loj rau ultrasonic atomization txau cov cuab yeej thiab cov kev pabcuam cuam tshuam hauv kev kho mob yuav tuav qhov nruab nrab txhua xyoo kev loj hlob ntawm ntau dua 20% hauv tsib xyoos tom ntej, dhau los ua qhov tseem ceeb ntawm kev loj hlob rau kev kho mob thev naus laus zis.
