Ozone disinfection apparatus for oral surgery instrumentsThis utility model relates to a kind of disinfector, especially dental instrument ozone gas disinfector.
Now, in department of stomatology, Hospital, the anti-institute of tooth,, bring difficulty for the sterilization of clinical dental instrument because dental instrument uses the popularity of object and the high particularity of sterilization requirement.At first, the oral cavity is various antibacterials and the virus position of easily living away from home, its quantity can reach hundreds of more than, wherein many is pathogenic bacterium.Secondly, the internal structure that dental instrument has is meticulous, has micromachine, sealing ring etc., the non-refractory that has, perishable, easily get rusty, and sterilization method commonly used such as high steam, antiseptic solution soak, ultraviolet radiations etc. come with some shortcomings again and limitation.So dental instrument sterilization at present is a comparatively weak ring in department of stomatology, Hospital, the anti-institute of the tooth sterilizing part.
The chemical property of ozone is active, belongs to strong oxidizer.It has intensive bactericidal action, can kill vegetative forms of bacteria and brood cell, virus, fungus, destroy Botulinum toxin etc.It can be directly and cell have an effect, cause the oxidation-reduction process blocking-up of the substance metabolism of antibacterial, thus the growth that destroys antibacterial with bred, cause the death of antibacterial, be listed in high effect disinfectants.The sterilization of employing ozone gas has the advantages that diffusibility is good, permeability is strong, and the antibacterial inside and outside to apparatus all can produce kill activity; And ozone gas does not produce high temperature, and toxic residue is little, decompose fast, so less to the corrosivity of apparatus, can prolong service life of apparatus.Thereby, high-concentrated ozone gas depoisoning a kind of good disinfectant measure of can yet be regarded as.Also adopt this class sterilization method as " a kind of box ozone sterilization device (ZL90214091.4) ", " dentistry disinfector (ZL912043140.8) " patent.But because its ozonator adopts wavelength all>2000

, thereby the ozone concentration of generation is on the low side, can not kill antibacterial in short-term effectively; Or not having ozonolysis equipment in the disinfector, the leaking to bring to environment of ozone polluted and to the harm of operator's health; Or though the ozone decomposer arranged, adopting wavelength is 2000
~4000
Light source irradiation handle, easily cause high temperature and influence the aging of apparatus parts.
This utility model is intended to overcome the deficiency that above-mentioned disinfector exists, provide the special low pressure mercury lamp of a kind of employing to excite high-concentrated ozone gas that dental instrument is carried out sterilization, and have an automatic disinfector of controlling of closed that contains the ozonolysis equipment of special ozone decomposition material composition, can remove operator's trouble and worry.
This utility model can be realized by following technical proposals.
A kind of dental instrument ozone gas disinfector of being made up of casing, electric ballast, electronic control circuit and ozonized gas generator is characterized in that: the ozonized gas generator that can excite high-concentrated ozone gas to take place at casing inner top rear side is a kind of special low pressure mercury lamp; Ozonolysis equipment and ozonolysis equipment open system are arranged in the inboard of casing inner bottom part; On the right side of casing inner bottom part the humidification dish is housed; In the intravital middle and upper part of case two stainless steel instruments dishes are set, card has cellular aperture, and a rustless steel cross bar is housed on every plate, for shelving apparatus; Being positioned at the casing right side is an airtight electric appliance control box, and case is built-in with an electronic automatic control device; Inward flange at hermatic door is stained with the sealing strip that the silicone rubber of anti-ozone is made.Described caliber<the 20mm that can excite the special low pressure mercury lamp of high-concentrated ozone gas, its profile is a straight pipe type, or the H type, or the U type, the wavelength of its generation<2000

The described special low pressure mercury lamp that can excite high-concentrated ozone gas, in
work 15 minutes the time, ozone concentration>200mg/m in the case
3Described ozonolysis equipment is to be built-in with a kind of ozone of making of material that can ozone decomposition at a rustless steel closed enclosure to decompose sheet and aerofoil fan, in rustless steel closed enclosure both sides one wicket is arranged respectively, have the cam of opening or closing the both sides wicket on the axle of AC servo motor, aerofoil fan is independently controlled by control circuit.Described humidification dish is a kind of long-pending square or circular rustless steel water dish of certain surface that has.Described electronic automatic control device adopts integrated circuit to form, and also comprises start-up circuit, intervalometer, relay, controllable silicon, frequency divider, buzzer.Described box sealing door adopts corrosion resistant plate, cold-rolled steel sheet to make, and its surface is coated with anti-ozone coating, and appearance is again through the plastic-blasting or the processing of spraying paint.
A kind of dental instrument ozone gas disinfector that this utility model provides has following superiority:
(1) owing to adopt the special low pressure mercury lamp can excite high-concentrated ozone gas, when work in the time of 15 minutes, ozone concentration>200mg/m in its case3Work 30 minutes the time, colibacillary eradicative rate can reach 99.99%; Work 30 minutes the time, can destroy the hepatitis B surface purifying antigen.
(2) owing to adopt airtight technology, disinfector leakage rate when work is minimum, and its ozone leakage rate is better than the index of the one-level air standard of national regulation.
(3) owing to adopt the automatic ozone decomposer, arrive in the disinfecting time of setting, ozonolysis equipment is worked automatically, can remove ozone through a few minutes, and residual volume reaches the index of national industrial hygiene standard.
(4) owing to adopt electronic automatic control device, disinfector has auto-conversion function, and intuitive display, easy to operate is a kind of ideal dental instrument sterilize instruments.
