Antimicrobial Coatings siv Ultrasonic Tsuag Nozzles
Ultrasonic tshuaj txau thev naus laus zis yog siv los pleev cov tshuaj tua kab mob rau ntau yam kev lag luam los ntawm kev kho mob, zaub mov, ntaub, cov khoom siv hluav taws xob rau kev tsim kho cov khoom siv. Tshawb cov tshuab hluav taws xob yog qhov zoo tshaj plaws rau cov ntawv thov uas xav tau cov tshuaj ua kom tsawg ntawm cov tshuaj tua kab mob ua kom haum rau kev ua haujlwm rau ib qho chaw. Cov piv txwv zoo yog nyiaj, tooj thiab zinc oxide, zirconium, Zinc Omadine® (zinc pyrithione), kub nanoparticles thiab titanium dioxide raws antimicrobial cov ntaub ntawv siv los ua colony inhibitors hauv textiles, kws kho mob kho mob thiab lwm qhov chaw
Nyiaj nanoparticles piv txwv yog cov khoom siv kim thiab cov tuam ntxhab xav tau kev txhaj tshuaj zoo nrog me me lossis tsis muaj pov tseg. Cov tshuaj plume plau los ntawm ultrasonic cov tshuaj tsuag nozzle tuaj yeem yooj yim zoo li tus thiab qhov nrawm ntawm cov tshuaj tsuag ntsig tswj tau. Yog tias txheej txheej catheter, ib qho ultrasonic nozzle feem ntau nrog cov kua txaij nqaj nrog qhov nrawm qis yuav tau siv. Hauv kev sib piv, ib qho sib txawv ntawm ultrasonic nozzles nrog vortex configuration khiav ntawm ntau dua velocities yuav raug siv rau txheej textiles. Ob txoj kev teeb tsa ua kom siab hloov mus rau qhov zoo ntawm cov khoom siv txheej, khaws cov pov tseg kom tsawg kawg thaum tswj kev tsim khoom hla.
Antimicrobial Tsuag Tsuag Tsho Rau Hauv Kev lag luam Khoom Noj
Tsis zoo li kev kho mob, cov ntaub thiab cov khoom siv kev tsim kho uas feem ntau siv cov nyiaj raws li cov qauv tshuaj tua kab mob, kev lag luam khoom noj khoom haus tau siv ntau daim ntawv pom zoo los ntawm FDA los kho ntau cov khoom noj khoom haus. Piv txwv, hauv kev lag luam nqaij, Lauric Arginate (LAE) yog siv dav hauv kev npaj los noj cov nqaij (RTE) ua cov tshuaj tua kab mob hauv cov tshuaj hauv cov zaub mov tsawg thaum lub sijhawm kev tsim khoom. Thaum LAE siv nyob rau hauv cov tshuaj tsawg kawg, FDA xav tias kev tua kab mob yog "Ua Cov Khoom Siv," yog li zam nws los ntawm cov neeg siv khoom kawg sau npe. Ultrasonics tsuag nozzles tuaj yeem hno koob tshuaj RTEs nrog micron qib qhov tseeb thiab siab sib txawv, tswj hwm FDA cov cai thiab sau cim zam. Hauv kev lag luam ci kev siv tshuab ultrasonic tshuaj tsuag yog siv tshuaj tsuag poov tshuaj sorbate los inhibit pwm tsim. Ultrasonics minimizes pov tseg ntawm potassium sorbate, tab sis kuj tus nqi ntawm cov khoom tso tawm mus rau ib puag ncig raws li cov pa tawm.
FDA tau teev ntau ntau kaum daim ntawv pom zoo rau cov khoom siv tshuaj tua kab mob thiab cov qauv tshuaj tam sim no tau thov los tshuaj txau, xws li tsev neeg ntawm sodiums (benzoate, diacetate, propionate, hypoclorite, octanoate). Tus nab npawb ntawm cov acids xws li propionic, acetic, sorbic, citric thiab lactic. Cov npe no tseem muaj ntau qhov sib xyaw xws li lactic, citric acids nrog potassium hydroxide. Thaum kawg cov kab mob bacteriophage npaj, carnobacterium thiab lactoferrin raug txau rau cov khoom noj khoom noj uas ua tshuaj tua kab mob. Nws tsis paub nyob rau lub sijhawm no yog tias ib qho ntawm cov ntaub ntawv no tau txau nrog ultrasonic nozzles, tab sis kev tsim kho muaj zog ntawm peb cov thev naus laus zis ultrasonic thiab qhov tseeb tias nyob microbes tau atomized, qiv peb xav tias ntau ntawm cov chemical no tau txau nrog ultrasonic tshuaj tsuag. thev naus laus zis.
