When the utility model works, the hand machine for dentistry needs sterilization is driven to the disinfection optical cavity provided with the combined light source; after a switch is pressed down, the utility model can carry out preheating and strong-light irradiation in succession, and the surface temperature of the sterilized piece irradiated by lights can reach more than 300 DEG C. instantaneously; thus, pathogens adhere to the surface of the sterilized piece are killed; the temperature of a plastic piece at the inner part of the sterilized hand machine is no more than 120 DEG C. The hand machine sterilizing device for dentistry has the advantages of short sterilization time, thorough sterilization, no damage to the sterilized pieces, no pollution, small volume, convenient operation, etc. The utility model is suitable to be placed on a comprehensive therapeutic table for dentistry to carry out real-time sterilization for the hand machine for dentistry, and the utility model has the advantages of low use cost and long service life.
Description
Technical field
This utility model relates to a kind of device that dental handpiece is sterilized.
Background technology
At present to the medical equipment sterilization method methods such as medicining liquid dipping, high temperature steaming, high-temperature steam, high-temperature baking and vacuum high-temperature the most generally of going out.Concerning the sterilization of dental handpiece, roasting its temperature of high temperature must be lower than 134 ℃, in order to avoid the working of plastics of infringement mobile phone inside, but is invalid for the high temperature resistant pathogenic bacteria (as bacillus subtilis) that surpasses a temperature, by boil sterilize limited especially.Adopt routine disinfection liquid (as ethanol etc.) to soak and also just kill the part microorganism selectively, and owing to soak time is generally all longer.In recent years the comprehensive sterilizing machine of a kind of novel vacuum high-temperature enters China market, but the price height is difficult to popularize.
Summary of the invention
The purpose of this utility model provides a kind of being adapted in the dental treatment, the dental handpiece high light bactericidal unit that dental handpiece is sterilized in real time, sterilized, can reach rapidly, sterilization thoroughly, reliable, directly perceived, province's expense, free of contamination effect, and the xenon lamp working life can reach 1,000,000 times.
According to dental handpiece steriliser of the present utility model, it comprises power supply and sterilization optical cavity, it is characterized in that, is provided with the laser pump cavity of coaxial placement in the sterilization optical cavity, and this laser pump cavity is cylindrical, and inner surface is diffuse-reflectance, in this laser pump cavity combined light source is housed.
Adopt advanced switching pulse power technology and will sterilize optical cavity and xenon flash lamp power supply are designed to one, make the volume of equipment can reduce to use like this to be fit to place on the dental unit.
Adopt halogen tungsten lamp or heater strip pre-heating sterilisation optical cavity, can reduce the luminous energy of xenon flash lamp sterilization so significantly.
Adopt two xenon lamps to work simultaneously, the luminous energy of every lamp output can reduce by one times, promptly exports energy and reduces by one times, becomes the order of magnitude to increase under single lamp situation than using the service life of xenon lamp like this.
Laser pump cavity adopts the high reflection of outer surface plating silverskin, the cylindrical glass diffuse-reflectance optical cavity of inner surface hacking, and can make the surface irradiation energy density that is sterilized part that places in the sterilization optical cavity is that this is favourable for reaching thorough sterilization uniformly.
Steriliser also is provided with the dental handpiece anchor clamps, is easily and fast for the installation of mobile phone and the operation of taking off, anchor clamps can be easily from optical cavity one end advance or pull out.
Adopt technique scheme to be implemented in the dental treatment process dental handpiece is sterilized in real time, disinfecting time is short, sterilization is thorough, pollution-free, sterilization is directly perceived, patient is the most acceptant, and only needs disposable input, and use cost is low, is easy to promote.
Brief description of drawings
Below in conjunction with drawings and Examples this utility model is further specified:
Fig. 1 is the axonometric chart of dental handpiece steriliser of the present utility model;
Fig. 2 is the schematic cross-section of sterilization optical cavity;
Fig. 3 is the sketch map of dental handpiece clamp structure;
Fig. 4 is the circuit working functional-block diagram.
Preferred implementation
In Fig. 1: the 1-guidance panel; The 2-power supply box; The 3-optical cavity of sterilizing; 4-dental handpiece anchor clamps; 5-guide rod carrying handle.During operation, hold guide rod carrying handle (5) dental handpiece anchor clamps (4) can be equipped with an end that is sterilized part insert or pull out the sterilization optical cavity (3).
In Fig. 2: the inner surface hacking of glass laser pump cavity (7), outer surface plating high reflectance silverskin; Sterilization optical cavity skin is the cylinder (6) of aluminum structure, not only dispels the heat but also protect inner layer glass laser pump cavity (7); Xenon flash lamp (8), the luminous light of halogen tungsten lamp (9) converge at intracavity with luminous energy after laser pump cavity (7) reflection, can make the luminous energy uniform irradiation place the each several part that is sterilized part (dental handpiece) (10) surface in chamber simultaneously.
Operation principle in Fig. 3 is: dental handpiece is put into retaining ring (12) by the tight cover (11) of end face, during the loading and unloading mobile phone, rotary handle (17), guide rod (15) advances or retreats, utilize the bell of overcoat (14) front end to compress or loosen retaining ring (12), mobile phone is clamped or unclamp by thimble (13).Connecting plate (16) is fixed on the guide rod carrying handle (4) among Fig. 1, and the swing carrying handle then can push mobile phone or pull out the sterilization optical cavity.
In Fig. 4: 18-220V alternating current joint; 19-adds electric switch; The 20-starting switch of sterilizing; The 21-master controller; The pre-heat controller of 22-; The 23-halogen tungsten lamp; The 24-critesistor; The 25-low-voltage rectifier; The 26-high-frequency inverter; The 27-re-pressure device; The 28-high voltage rectifier; 29-energy storage electricity becomes device; The 30-xenon flash lamp; The 31-control of lighting a lamp; 32-xenon lamp trigger.The operation principle of circuit is: after on and off switch (19) closes, power supply powers up, behind Push switch (20), disinfecting process begins, master controller (21) sends instruction to halogen tungsten lamp (23) control of lighting a lamp to pre-heat controller (22), raising when changing to corresponding 100-110 ℃ resistance with cavity temperature of critesistor (24) by placing laser pump cavity then stops heating.Start-up point lamp controller (31) sends signal to xenon lamp trigger (32) simultaneously, xenon lamp (30) is lighted, xenon lamp resistance moment is changed to by infinity and is tending towards " zero " value, the electric energy that is stored in advance on the electricity change device (29) discharges by xenon lamp (30), change the high brightness pulsed light into, after energy has been put on the electricity change device, xenon lamp extinguishes immediately, the xenon lamp internal resistance is converted into infinity again, again electricity change device is charged to predetermined value and waits for that next xenon lamp triggers discharge, when the xenon lamp number of light emission times reaches the guide number that sets in advance in the xenon lamp controller, then stop discharge automatically and cut off the charging that electricity becomes device (29) by master controller, whole disinfecting process finishes.When needs carry out the next round sterilization, behind the Push switch (20), repeat said process again again.
