Description
Technical field:
This utility model relates to medical apparatus and instruments, particularly a kind of protective helmet that prevents electro-optical eye occupation disease.
Background technology:
Industrial, while carrying out electric welding or gas welding, owing to not carrying protective glasses or protective mast, or protective glasses protection effect is bad, the normal damage of penetrating a large amount of ultraviolet in arc light during because of electric welding and cause eye.Ultraviolet operation common under working condition has: electric welding and gas cutting; The heliotype of printing industry; The various light application of film industry; The electrode steel-making of temperature more than 3000 DEG C; Dazzle the eyes worker under dazzling environment on high mountain, snowfield, desert, sea etc., all can accept for a long time a large amount of ultraviolet.Be subject to the cornea of ultraviolet radiation, visible cell nuclear swelling, chromatolysm, necrosis come off.Exfoliation of corneal epithelium, leaves base cell.Conjunctival epithelium is outer to depart from, base cell degeneration.After eye acute exposure ultraviolet, general a few hours just start to have symptom, and incubation period is relevant with the ultraviolet strength time of acceptance.Main clinical manifestation is ocular foreign bodies sense, discomfort, and when serious, eye has burn feeling and severe pain, sheds tears, photophobia, blepharospasm.Examination of eyes: bulbar conjunctiva congestion and edema, corneal epithelium point-like or flaking, corneal sensation is gone down, and pupil is spastic to be dwindled, short-term visual deterioration.Simultaneously with face and eyelid skin flushing, erythema.Prolonged and repeated ultraviolet radiation, can cause chronic blepharitis and conjunctivitis.So electro-optical eye has become a kind of occupation disease, be even more important for the prevention of this occupation disease.The safety device of this occupation disease of prevention at present, as most in electric welder's helmet is hands act formula, on its face shield, be provided with eyeglass, use different face shields instead according to welding operation difference, during as electric welding, adopt No. 7 face shields (referring to filter glass eyeglass), this face shield can effectively stop strong ultraviolet, and during for gas welding or gas cutting, can adopt common sunglasses etc.This structure is the structure of commonly using on the market, and still, its one hand lifts operation, is unfavorable for liberating both hands, and especially, in the time that needs proficiency handheld component is welded, shortcoming highlights.Unresolved this technical problem, occurred the improvement of some helmet-types, adopted the mode of the helmet to be fixed on head by face shield, it liberates both hands, and, eyeglass also has the boosted voltage of employing eyeglass, stimulates FC color depth according to electric light, to adapt to different electric welding operations, but, this fraud is expensive, and repeatedly receives electric light and stimulate the situation that causes booster circuit to damage to happen occasionally, and popularity rate is wideless.In addition, the toxic gas of generation when welding and spark splash, easily respiratory system or the epidermis skin to user damages, and uses the mode of the helmet also can avoid this situation to occur.As Chinese patent application 200920291526.4 discloses a kind of electric welder's helmet, it drives eyeglass rise or fall by driver part, and arranges and consider malicious parts at oral area, it is controlled that this structure rises eyeglass, when use, fall, the used time does not rise, and passes through to consider malicious parts and reduce the injury of toxic gas to human body while welding, but, its defect is: 1, eyeglass is what fix, although fall and start easily,, for difference welding, need to change the different helmets or eyeglass.2, consider malicious component locations and fix, and after the helmet wears, the space after space or the brain at its neck place, easily enters toxic gas, and the long ratio difference of individual face, consider the mouth and nose position that malicious parts position cannot adapt to majority.3, the sputter of splash spark causes clothes, and especially the medicated clothing of incidence, chest is usually damaged.4, wear after the helmet, in the helmet, temperature is higher, and wearer is uncomfortable.In view of above-mentioned technological deficiency, a kind of simple in structure, easy to use in the urgent need to occurring, eyeglass is interchangeable, and respirator position is adjustable, and inner helmet ventilation, blocks a kind of protective helmet that prevents electro-optical eye occupation disease of protection spark sputter on a large scale.
Summary of the invention:
