Abstract
The sterilization method is characterized by that the material or body to be sterilized is placed in D. C. electric field for 1-15 min. The invented device for implementing said sterilization method is characterized by that it possesses two electrodes covered with insulating material layer, those electrodes are respectively connected with positive pole and negative pole of the D. C. power supply, and its electric field intensity is 100-6000 v/cm. Said invention is simple in structure and operation, low in cost and can quickly kill all bacteria on the material or body and at the interior of pipe, and doesn't damage those materials.
Description
The present invention relates to a kind of method and device of sterilization.
In the method for Applied Physics phenomenon to material or object sterilization, common have a ultraviolet irradiation method, corresponding device thereof is used in concrete operations often, ultraviolet ray disinfector for example, but owing to had 10% to produce photoreactivation approximately by the pathogenic microorganism behind the ultraviolet radiation, and can not sterilize to the apparatus pipe interior, so ultraviolet is not a sterilization light source reliably, thereby relevant therewith device can not be sterilized effectively.Though the disinfector as pulse hernia lamp is reliable to the apparatus surface sterilization in addition, and is powerless to the sterilization of equipment pipe interior.
The purpose of this invention is to provide a kind of method and device, to remedy the above-mentioned deficiency of prior art with the DC electric field sterilization.
The feature of method of the present invention is that the material that will sterilize or object are placed in the DC electric field about 1-15 minute.
The feature of implementing the employed device of said method is that two electrodes that wrapping insulation material layer are arranged, is connected with negative pole with the positive pole of dc source respectively, its electric field intensity be 100-6000 lie prostrate/centimetre.
Method of the present invention and used device are extremely simple, and cost is low, and operation easily can be killed on material or the object rapidly and the inner all antibacterials of pipe, and the article that are sterilized are not had damage.
Further specify method of the present invention and used device below by embodiment and accompanying drawing.
Accompanying drawing is an apparatus structure sketch map of the present invention.
The external packets of electrode in the accompanying drawing (1) and (2) insulation material layer, and they are connected with the positive and negative electrode of dc source (3) respectively, electric field intensity be 100-6000 volt/centimetre.
Embodiment 1, the sterilization problems of oral cavity high speed turbine mobile phone fails to solve both at home and abroad so far, can deal carefully with method and apparatus of the present invention, two metal copper wires that are with insulation material layer are inserted respectively in the passage and limbers of turbine hand machine for this reason, and this two lead connect on the negative pole of dc source, in addition with the sheet copper of outsourcing insulation material layer, connect the positive pole of dc source, with this copper coin the turbine hand machine shell is wrapped, the antibacterial on the turbine hand machine of switching on after 3 minutes is eliminated entirely.Through 3 days culture experiment, not seeing had bacterial growth.Used dc source is a plurality of aneroid battery, and its voltage is 300 volts, and the mobile phone diameter is 1cm.Sheet copper also can be used closeer copper mesh instead.
Embodiment 2: for the fibergastroscope sterilization, the copper wire among the embodiment 1 is inserted it get in the biopsy hole, the above-mentioned sheet copper that is surrounded by insulation material layer of gastroscope external is wrapped, and switches on after 1 minute, has received the effect of sterilization.Used DC voltage is 5000V, and the external diameter of gastroscope is 1.26cm.
Similar experiment has been done in laparoscopically sterilization, received and the identical effect of gastroscope.To insert in the laparoscopically pipe as the lead of negative pole during experiment, to duodenofiberscope, through the female mirror of duodenum fiber biliary tract, extract peritoneoscope, thoracoscope, internal medicine diagnosis peritoneoscope through the sub-mirror of duodenum fiber biliary tract, fiber endoscopy, fibro-colonoscope, enterofiberscope, gallbladder, the medical treatment peritoneoscope, NCS needle-like peritoneoscope, department of obstetrics and gynecology treatment peritoneoscope, arthroscope all obtains similar effects.
Embodiment 3: when RMB or case history are carried out disinfection, with thickness is that the RMB of 1cm is placed on and is surrounded by insulation material layer and is a bit larger tham between the copper coin of RMB or case history, they connect the both positive and negative polarity of 300 volts of dc sources respectively, switch on 10 minutes, have just received the disinfectant effect.If increase the thickness of RMB or case history, then DC voltage should increase.
Embodiment 4: for fresh-keeping, the vegetables Lay that 10cm is thick is placed between two sheet coppers that are surrounded by insulation material layer, switches on and has received the effect that sterilization is fresh-keeping after 10 minutes, and supply voltage is 5000 volts, and the distance between two copper coins is 10cmn.
Above-mentioned 4 embodiment illustrate that method of the present invention and used device can kill HIV (human immunodeficiency virus), hepatitis B virus, cancerous cell, bacterial propagule and brood cell rapidly, understanding by the applicant, this is owing under the effect of DC electric field, the Na on the pathogenic microorganism cell membrane walls
+, K
+, Cl
-, Ca
2+The normal physiological state destroyed, promptly ionic motion is subjected to the inhibition of DC electric field, and causes the death of pathogenic microorganism.
Claims (3)
1, a kind of sterilizing methods, it is characterized in that will sterilization material or object be placed in the DC electric field 1-15 minute.
2, implement the employed device of the described method of claim 1, it is characterized in that the electrode (1) and (2) that have two to be surrounded by insulation material layer being connected with the both positive and negative polarity of dc source respectively, its electric field intensity be 100-6000 lie prostrate/centimetre.
3, device as claimed in claim 2 is characterized in that described electrode (1), (2) can be tinsel or metallic plate or wire netting.
