Electro optic ophthalmia
Tsis tas li ntawd, peb yuav tsum to taub tias luv luv - lub sij hawm raug rau ultraviolet tshuaj tua kab mob teeb kuj yuav muaj qee yam cuam tshuam rau lub cev, uas yuav ua rau electro- optic ophthalmia.
Tom qab tshwm sim ntawm cov kab mob no, cov neeg mob feem ntau muaj cov tsos mob xws li qhov muag liab thiab o, qhov muag qhuav thiab kua muag. Hauv qhov xwm txheej hnyav, lawv tseem yuav ua rau qee qhov kev puas tsuaj rau lub zeem muag. Feem ntau, yog tias koj irradiate lub teeb ultraviolet rau 30 mus rau 60 feeb, nws yuav ua rau qhov tshwm sim ntawm electro-optic ophthalmia, uas feem ntau yog tshwm sim los ntawm kev nqus ntawm ntau cov ultraviolet rays los ntawm cov hlwb ntawm pob txha. epithelium thiab cov ntaub so ntswg ntawm conjunctiva.
Yuav ua li cas ntxiv tiv thaiv tus kab mob coronavirus tshiab tau dhau los ua lub ntsiab lus ntawm kev txhawj xeeb rau tib neeg tom qab lawv rov ua haujlwm. Cov tshuaj tua kab mob ultraviolet tau dhau los ua txoj kev siv tshuaj tua kab mob zoo tshaj plaws rau qee qhov chaw lossis cov tib neeg vim nws txoj kev siv yooj yim, tsis muaj kev hloov ntau zaus thiab tus nqi nruab nrab. Txawm li cas los xij, yog tias lub teeb tshuaj tua kab mob ultraviolet tsis siv kom raug, nws tseem yuav ua rau peb puas tsuaj sai dua tus kab mob. Yog li ntawd, xyuam xim rau cov ntsiab lus hauv qab no hauv kev siv:

2. Ultraviolet disinfection lamps in schools and other public places shall be installed in a safe and appropriate position to avoid children's touch. Special control switches shall be set and controlled by special personnel to prevent misoperation.
3. Ultraviolet sterilization nrog lub zog tsim nyog thiab ntau npaum li cas yuav tsum raug xaiv raws li thaj chaw ntawm cov chaw tshwj xeeb kom ua tiav cov txiaj ntsig zoo kom tsis muaj menyuam. Feem ntau, lub sijhawm tshuaj tua kab mob irradiation yuav tsum tsis pub tsawg tshaj 30 feeb. Nws raug nquahu kom muab tshuaj tua kab mob hauv chav ntawm 10 15 square metres rau 40 feeb.
4. Tsis txhob siv cov tshuaj tua kab mob ultraviolet ua lub teeb pom kev zoo. Nws tsis tsim nyog qhib lub teeb ultraviolet rau lub sijhawm ntev. Lub sijhawm tshuaj tua kab mob yuav tsum yog 30 feeb-1 teev.
