Iingozi ezinokwenzeka ezibangelwa ukusebenzisa i-lasers: umonakalo we-laser radiation, umonakalo wombane, umonakalo owenziwe ngoomatshini, umonakalo werhasi yothuli.

1.1 Inkcazo yeklasi yeLaser
Iklasi 1: Ikhuselekile ngaphakathi kwesixhobo. Ngokuqhelekileyo oku kungenxa yokuba umqadi uvalelwe ngokupheleleyo, njengakwi-CD player.

I-Class 1M (Iklasi ye-1M): Ikhuselekile ngaphakathi kwesixhobo. Kodwa kukho iingozi xa ujoliswa ngeglasi yokukhulisa okanye ngemakroskopu.

Udidi 2 (Iklasi 2): Ikhuselekile phantsi kweemeko zokusetyenziswa eziqhelekileyo. Ukukhanya okubonakalayo kunye nobude be-400-700nm kunye ne-blink reflex yeso (ixesha lokuphendula i-0.25S) linokuphepha ukulimala. Ezo zixhobo zihlala zinamandla angaphantsi kwe-1mW, njengezikhombisi zelaser.

Iklasi ye-2M: Ikhuselekile ngaphakathi kwesixhobo. Kodwa kukho iingozi xa ujoliswa ngeglasi yokukhulisa okanye ngemakroskopu.

I-Class 3R (i-Class 3R): Amandla adla ngokufikelela kwi-5mW, kwaye kukho umngcipheko omncinci wokulimala kwamehlo ngexesha le-blink reflex. Ukujonga kulo mqadi kangangemizuzwana emininzi kunokubangela umonakalo okhawulezileyo kwiretina

Udidi 3B: Ukuvezwa kwimitha yelaser kunokubangela umonakalo okhawulezileyo emehlweni.

Iklasi yesi-4: I-Laser inokutshisa ulusu, kwaye kwezinye iimeko, ukukhanya kwelaser esasazekileyo kunokubangela umonakalo wamehlo kunye nolusu. Banga umlilo okanye ugqabhuko-dubulo. Iilaser ezininzi zamashishini kunye nezesayensi ziwela kule klasi.

1.2 Inkqubo yomonakalo we-laser ikakhulu yimpembelelo ye-thermal ye-laser, uxinzelelo olulula kunye ne-photochemical reaction. Amalungu awonzakeleyo ikakhulu ngamehlo kunye nolusu lomntu. Umonakalo wamehlo omntu: Inokubangela umonakalo kwi-cornea kunye ne-retina. Indawo kunye noluhlu lomonakalo luxhomekeke kwi-wavelength kunye nenqanaba le-laser. Umonakalo owenziwe ngelaser emehlweni abantu untsokothile. Imiqadi yelaser ethe ngqo, ebonakalisiweyo kwaye ibonakaliswe ngokwahlukeneyo inokonakalisa amehlo abantu. Ngenxa yempembelelo yokugxila kwiliso lomntu, ukukhanya kwe-infrared (okungabonakaliyo) okukhutshwe yile laser kuyingozi kakhulu kwiliso lomntu. Xa le radiation ingena kumfundi, iya kujoliswa kwiretina kwaye emva koko itshise iretina, ibangele ukulahleka kombono okanye ubumfama. Umonakalo eluswini: I-laser enamandla ye-infrared ibangela ukutshisa; I-ultraviolet lasers inokubangela ukutshisa, umhlaza wolusu, kunye nokwandisa ukuguga kolusu. Umonakalo we-Laser eluswini ubonakaliswa ngokubangela amanqanaba ahlukeneyo e-rashes, i-blisters, i-pigmentation, kunye nezilonda, de izicubu ezingaphantsi kwe-subcutaneous zitshatyalaliswe ngokupheleleyo.

1.3 Iiglasi ezikhuselayo
Ukukhanya okukhutshwa yilaser yimitha engabonakaliyo. Ngenxa yamandla aphezulu, nokuba umqadi osasazekileyo usenokubangela umonakalo ongenakulungiseka kwiiglasi. Le laser ayizi nezixhobo zokukhusela amehlo e-laser, kodwa ezo zixhobo zokukhusela amehlo kufuneka zinxitywe ngamaxesha onke ngexesha lokusebenza kwelaser. Iiglasi zokhuseleko zeLaser zonke zisebenza kubude obukhethekileyo bobude. Xa ukhetha iiglasi ezifanelekileyo zokhuseleko lwe-laser, kufuneka ukwazi olu lwazi lulandelayo: 1. I-laser wavelength 2. Imowudi yokusebenza kwe-Laser (ukukhanya okuqhubekayo okanye ukukhanya kwe-pulsed) 3. Ubuninzi bexesha lokuvezwa (ukuqwalasela imeko embi kakhulu) 4. Ubuninzi bombane obuninzi bombane ( I-W / cm2) okanye ubuninzi be-irradiation yamandla obuninzi (J / cm2) 5. Ubuninzi obuvumelekileyo be-exposure (MPE) 6. Ubuninzi bokukhanya (OD).

1.4 Ukonakaliswa kombane
Umbane wobonelelo lwamandla wesixhobo selaser sisigaba esithathu esitshintshanayo ngoku 380V AC. Ufakelo kunye nokusetyenziswa kwezixhobo ze-laser kufuneka zisekelwe ngokufanelekileyo. Ngethuba lokusetyenziswa, kufuneka ubeke ingqalelo kukhuseleko lombane ukukhusela ukulimala kombane. Xa uqhaqha i-laser, ukutshintshwa kwamandla kufuneka kucinywe. Ukuba kwenzeka ukulimala kombane, amanyathelo onyango achanekileyo kufuneka athathwe ukukhusela ukulimala okwesibini. Iinkqubo zonyango ezichanekileyo: cima amandla, ukhulule ngokukhuselekileyo abasebenzi, biza uncedo, kwaye ukhaphe abonzakeleyo.

1.5 Ukonakala koomatshini
Xa ugcina kwaye ulungisa i-laser, ezinye iindawo zinzima kwaye zinemiphetho ebukhali, enokubangela umonakalo okanye ukusikeka ngokulula. Kuya kufuneka unxibe iigloves ezikhuselayo, izihlangu ezichasene ne-smash kunye nezinye izixhobo zokukhusela

1.6 Umonakalo werhasi nothuli
Xa kusenziwa inkqubo ye-laser, uthuli oluyingozi kunye neegesi ezinetyhefu ziya kuveliswa. Indawo yokusebenzela kufuneka ixhotyiswe ngokufanelekileyo ngezixhobo zokungenisa umoya kunye nokuqokelela uthuli, okanye unxibe iimaski zokukhusela.

1.7 Iingcebiso ngokhuseleko
1. La manyathelo alandelayo anokuthathwa ukuphucula ukhuseleko lwezixhobo zelaser:
2. Ukunciphisa ukufikelela kwizibonelelo ze-laser. Cacisa amalungelo okufikelela kwindawo yokusetyenzwa kwelaser. Izithintelo zinokuphunyezwa ngokutshixa ucango kunye nokufakela izibane ezilumkisayo kunye neempawu ezilumkisayo ngaphandle kocango.
3. Phambi kokuba ungene elabhoratri ukuze usebenze ukukhanya, xhoma uphawu olulumkileyo olukhanyayo, layita isibane esilumkisayo, kwaye wazise abasebenzi abakufutshane.
4. Phambi kokuba usebenzise i-laser, qinisekisa ukuba izixhobo ezijoliswe ekukhuseleni izixhobo zisetyenziswa ngokuchanekileyo. Kubandakanya: iibhaffles ezikhanyayo, iindawo ezikwazi ukumelana nomlilo, iiglasi, iimaski, izitshixo zeengcango, izixhobo zokungenisa umoya, kunye nezixhobo zokucima umlilo.
5. Emva kokusebenzisa i-laser, cima i-laser kunye nonikezelo lwamandla ngaphambi kokuba uhambe
6. Phuhlisa iinkqubo zokusebenza ezikhuselekileyo, uzigcine kwaye uzihlaziywe rhoqo, kwaye womeleze ulawulo. Ukuqhuba uqeqesho lokhuseleko lwabasebenzi ukuphucula ulwazi lwabo ngothintelo lweengozi.
