Covlaser excimer- feem ntau emitting ultraviolet B (UVB) lub teeb ntawm308nm ua- yog dav siv nyob rau hauv dermatology rau tsom phototherapy nyob rau hauv tej yam kev mob xws li psoriasis, vitiligo, thiab eczema. Tsis zoo li siab - lub zog phais lasers, excimer laser muab ibtsis yog-thermal, tsis yog-ablativekoob tshuaj UV hluav taws xob rau thaj chaw ntawm daim tawv nqaij, sparing ib puag ncig cov ntaub so ntswg. Txawm li cas los xij, txawm tias nws precision,308 nm UVB hluav taws xob ua rau muaj kev phom sij loj heev, tshwj xeeb tshaj yog rau lub qhov muag thiab tsis yog - hom tawv nqaij. Tsim nyogcov txheej txheem kev nyab xeebyog qhov tseem ceeb los tiv thaiv kev raug mob hnyav.
1. Tej yam tseem ceeb ntawm Excimer Lasers
A. Ocular Hazards
308 nm UVB yog nqus tau los ntawm lub pob kws thiab lub lens.
Kev raug mob hnyav tuaj yeem ua rauphotokeratitis(qhov mob "sunburn" ntawm lub pob kws), nrog cov tsos mob tshwm sim tom qab 6-12 teev tom qab- raug: liab, tearing, txawv teb chaws - lub cev hnov, thiab photophobia.
Kev mob ntev los yog rov tshwm sim tuaj yeem ua raucataract tsimlos yog conjunctival puas.
⚠️ Lus Cim: Qhov muag uatsis yogpom lub teeb UV- cov neeg mob thiab cov neeg ua haujlwm yuav raug pom yam tsis muaj kev paub tam sim ntawd.
B. Daim tawv nqaij raug mob
Overexposure tuaj yeem ua rauerythema (sunburn -zoo li cov tshuaj tiv thaiv), blistering, los yog hyperpigmentation.
Rov ua dua - koob tshuaj UV raug yog qhov paubpheej hmoo rau daim tawv nqaij carcinogenesis, txawm tias qhov kev kho mob excimer txo qis tag nrho lub cev raug piv rau tag nrho -lub cev UVB txee.
C. Kev pheej hmoo thib ob
Kev xav: Thaum UVB cuam tshuam tsis zoo ntawm ntau qhov chaw, cov hlau ci los yog cov cuab yeej nyob ze ntawm thaj chaw kho mob tuaj yeem tawg tawg.
Ozone tiam: Qee lub tshuab excimer qub tuaj yeem tsim cov kab ozone thaum ua haujlwm; Kev pom zoo kom muaj chav cua txaus.
2. Core Safety Measures
A. Kev Tiv Thaiv Qhov Muag- Tsis yog -Tshaj tawm
Txhua tus neeg hauv chav kho mob yuav tsum hnavUV- thaiv cov iav tsom iav tshwj xeeb ntsuas rau308nm ua.
Txheem ntshiabtsom iav kev nyab xeeblos yog looj tsom iav dubtsis txhob thaiv UVB zoo.
Eyewear yuav tsum:
Sau npe nrogKev tiv thaiv wavelength (piv txwv li, "UV 200-400 nm" lossis "308 nm thaiv")
Muabkev pab them nqi kho mobtiv thaiv peripheral raug
Yuav hnav los ntawmtus neeg mob, tus neeg teb xov tooj, thiab cov neeg soj ntsuam
✅ Kev xyaum zoo tshaj plaws: Sivopaque tsom iavlos yogpolycarbonate shieldsnrog ntawv pov thawj UV absorption. Rau kev kho mob ntawm lub ntsej muag nyob ze ntawm lub qhov muag, xav txog kev tiv thaiv ntxiv (xws li, hlau occluders los yog cov ntaub qhwv ntub rau ntawm daim tawv muag kaw)-tab sistsis txhob cia siab rau daim tawv muag ib leeg.
B. Tiv thaiv daim tawv nqaij
Npog tag nrho cov tawv nqaij uas tsis yog - hom phiajnrog phuam, ntaub ntaub, los yog UV-paque ntaub.
Thovbroad -spectrum sunscreen (SPF 50+)mus rau thaj chaw uas nyob ib sab yog tias tsis muaj kev pab them nqi tag nrho (txawm tias muaj kev cuam tshuam rau lub cev).
Siv covkoob tshuaj tsawg tshaj plawsraws li hom tawv nqaij thiab qhov tsawg kawg nkaus erythema koob tshuaj (MED) kuaj thaum tsim nyog.
C. Tswj Kev Kho Ib puag ncig
Ua kev kho mob hauv achav tshwj xeebnrog:
Cov cim ceeb toom ("UV Laser hauv Kev Siv - Kev Tiv Thaiv Qhov Muag Yuav Tsum") ntawm lub qhov rooj
Yam tsawg kawg nkaus reflective nto ze ntawm tes
Tsim nyog qhov cua tshuab
Xyuas kom covhandpiece taub yog ib txwm qhia ntawm lub hom phiaj ntawm daim tawv nqaij-Tsis txhob mus rau qhov muag lossis tsis pom lub cev.
3. Tus neeg mob-Txoj kev nyab xeeb tshwj xeeb
Qhia cov neeg mob kom kaw qhov muagthaum kho lub ntsej muag lossis tawv taub hau-txawm nrog tsom iav.
Tsis txhob kho qhov txhab nyob ze ntawm qhov muagtshwj tsis yog siv cov ntaub thaiv qhov muag tshwj xeeb raws li txoj cai nruj.
Cov ntaub ntawv kho tsis tau(dose, cheeb tsam, ntu ntu) txhawm rau tiv thaiv kev noj ntau dhau.
Tshuaj ntsuam rau photosensitizing tshuaj(piv txwv li, tetracyclines, thiazides, St. John's wort) ua ntej kho.
4. Kev cob qhia cov neeg ua haujlwm yuav tsum muaj
Txhua tus neeg ua haujlwm ua haujlwm lossis pab nrog excimer lasers yuav tsum tau txais kev cob qhia npog:
Xwm ntawm 308 nm UVB hluav taws xob thiab cov teebmeem lom
Kev siv thiab tshuaj xyuas ntawm UV-cov tsom iav tiv thaiv
Kev teb thaum muaj xwm txheej ceev rau qhov raug xwm txheej (xws li, qhov muag dej yogtsis yogqhia rau UV keratitis; Cov tsos mob thiab kev kho mob ophthalmology xa mus yog mob hnyav)
Ntaus-kev nyab xeeb kev ua haujlwm tshwj xeeb (piv txwv li, tswj qhov tseem ceeb, emission qhia teeb)
Kev cob qhia yuav tsum tau kho dua tshiabtxhua xyoolos yog thaum cov cuab yeej tshiab tau qhia.
5. Cov Khoom Siv & Kev Nyab Xeeb Kev Nyab Xeeb
Tsis tu ncua tshuaj xyuas cov handpiece rau cov kab nrib pleb los yog misalignment uas yuav ua rau cov kab tawg tawg.
Xyuas kom covemission qhia lub teebua haujlwm kom raug (feem ntau cov khoom siv teeb pom kev thaum ua haujlwm).
Tsis txhob hla kev ruaj ntseg interlocks lossis ua haujlwm nrog kev tiv thaiv kev puas tsuaj.
Xaus
Thaum lub 308 nm excimer laser yog ib qho cuab yeej tseem ceeb rau kev tsom mus rau phototherapy, nwsultraviolet tso zis xav tau kev hwm. Tsis zoo li cov lasers pom, UV hluav taws xob tsis pom thiab tsis mob thaum lub sijhawm raug- ua kom muaj kev tiv thaiv tseem ceeb. Los ntawm kev tswj hwm kev siv tsis tu ncuawavelength-kev tiv thaiv qhov muag tsim nyog, daim tawv nqaij tiv thaiv, thiabtswj cov txheej txheem khiav haujlwm, cov chaw kho mob tuaj yeem xa cov kev kho mob zoo thaum tiv thaiv cov neeg mob thiab cov neeg ua haujlwm los ntawm kev tiv thaiv kev puas tsuaj.
Nco ntsoov: in UVlaser kev nyab xeeb, koj yuav tsis hnov qhov kev puas tsuaj mus txog thaum nws lig dhau lawm. Kev tiv thaiv los ntawm kev qhuab ntuas- tsis tawm tsam- yog tus qauv kev saib xyuas.
Cov kev taw qhia no ua raws li ANSI Z136.3 (Kev Nyab Xeeb Siv Lasers hauv Kev Kho Mob) thiab ICNIRP cov lus pom zoo rau kev tiv thaiv UV hluav taws xob. Nco ntsoov ua raws li koj lub chaw tsim khoom cov lus qhia thiab cov cai tswj hwm hauv zos.
