Description

Sterilizer for dentistry

A kind of dentistry disinfector of dental care decontaminating apparatus, it is applicable to the sterilization use of worm gear head, straight handpiece car stone.

Provide condition owing to characteristics, temperature and the anatomic form thereof of physiology of oral cavity for various microorganisms, antibacterial and settling down of virus with propagation, a large amount of antibacterials have been posted in the adult oral cavity, its quantity is big, more than the kind classification, occupy first of each one of whole body, show according to the stomatology data, contain the microorganism of 200-400 kind in people's the oral cavity, containing bacterial number in every milligram of saliva is 1.5 * 10 ⁸These may give rise to diseases after germs have invaded the human body when resistance of human body weakens.At present particularly the worm gear head used of the therapeutic equipment that uses in dental operation of oral medical unit such as dentistry therapy instrument, straight handpiece car stone are because the new head of dismounting and change rapidly after the operation both at home and abroad, and the way that only adopts medicining liquid dipping or carry out high temperature steaming is carried out sterilizing.Because the wherein a lot of spare parts of its internal structure, complex geometry such as worm gear head straight handpiece Che Shi adopt the nonmetallic materials manufacturing, more part has adopted the manufacturing of bonding way in assembling, thereby can not stand ethanol one class sterilization medicinal liquid for a long time and soak and can not bear the high temperature steaming baking, thereby cause the shortcoming that head can not thorough disinfection.

The utility model proposes a kind of in order to overcome above-mentioned shortcoming without medicinal liquid immersion or high temperature steaming.The dentistry disinfector of the long tubular frame structure that its adopts alternately, even, spaced ultraviolet tube and ozonizer are formed utilizes ultraviolet penetrating to sterilize and ozone broad-spectrum disinfectant and worm gear head, straight handpiece, Che Shi etc. are carried out sterilization effectively.

This utility model dentistry disinfector is that it of realizing by following measure is made up of preceding bracing ring, back bracing ring, carrying bolt, tailstock, ultraviolet tube, ozonizer, exciting circuit and time control circuit block, expanded metal lath etc.Its structure as shown in Figure 1, ultraviolet tube before and after it is characterized in that being contained on the bracing ring and ozonizer alternately, evenly, be spaced circular or polygon and square, the identical two kinds of pipes of its quantity respectively be 2-6.Round diameter is the 40-230 millimeter.Polygon, square circumscribed circle diameter are the 70-260 millimeter.Work sterilization chamber diameter or polygon, square inscribed circle diameter are the 20-40 millimeter, and length is the 100-300 millimeter, shown in accompanying drawing 3 accompanying drawings 4.

Operation principle of the present utility model is that the mode of utilizing ultraviolet and ozonization characteristic to combine carries out disinfection to type medical instrument for dental use worm gear head, straight handpiece and car stone.Ultraviolet is strong to microorganism, antibacterial and virus its penetration power that carries out disinfection in the radiation mode, but, the apparatus complex geometry forms the dead angle because still easily being blocked, influence sterilization effect, and ozone is wide-spectrum bactericide, strong because of it for the gas diffusibility, can be full of each corner but it exist the penetration power difference weakness, both are in conjunction with carrying out sterilization thereby remedied weakness separately mutually and make Disinfection Effect remarkable, but the mini-fan accelerate ozone O that installs on the tailstock ₃Concentration is even.The operation of this dentistry disinfector and time by exciting circuit and the time control circuit finish.

This utility model compared with prior art has following advantage:

1. the worm gear head of type medical instrument for dental use use and the parts of straight handpiece generally adopt nonmetallic materials to make.The assembling of Che Shi etc. has also been adopted the binding agent cementation, therefore they can not bear immersion of medicinal liquids such as ethanol or the steaming and decocting of long period, and this dentistry disinfector has adopted ultraviolet rays and ozone to carry out disinfection and avoided the use medicinal liquid to soak or steaming and decocting, the service life that influence has improved worm gear head or straight handpiece greatly.

2. because ultraviolet tube utilizes ray to penetrate sterilization, its penetration power is strong, sterilization is fast.And ozone utilization diffusion sterilization can not occur sterilizing the dead angle they work simultaneously to have played and keep sterilizing separately advantage, the part of covering the shortage mutually, thereby the sterilization that has improved worm gear head, straight handpiece, Che Shi etc. effectively, changed that cross infection can not get solving for a long time in the dental operation shortcoming.

3. this dentistry disinfector, volume is little, in light weight, easy to use, and it can be placed directly on the dental operation platform and use, and has reduced attached facility or the equipment of helping such as sterilization medicinal liquid vessel, baking oven, electric furnace.
