Abstract

A medical toothbrush features that the cathode coating is connected to the negative electrode of battery A, whose positive electrode is connected via leaf sping with the negative electrode of battery B, whose positive electrode is connected to anode plate, and all of them are sealed in the cavity of brush except cathode coating and anode plate to form a open-loop circuit. When teeth are brushed, the saliva or tooth-consolidating agent plays the role of automatic switch to form a closed-loop circuit for medical purpose.

Description

Medical toothbrush

The present invention relates to a kind of medical toothbrush

Chinese patent CN1040918A disclose a kind of ' miniature ionic oral therapeutic device ', its profile such as same toothbrush, one group of conductive bristle of being made by tungsten-boron fiber composite is arranged in the bristle on the brush, this group conductive bristle links to each other with power cathode in the brush holder, on brush holder surface the bare metal sheet of a slice as positive plate is housed near bristle, it with brush holder in positive source be connected, during use, between conductive bristle and sheet metal, produce little electric current, thereby conductive bristle release of trace elements, to be used as treatment and control to oral disease, but this miniature ionic oral therapeutic device has following deficiency: the one, and its conductive bristle must be made in 1200--1300 ℃ high-temperature hydrogen medium, has certain degree of difficulty; The 2nd, conductive bristle is that a kind of tungsten-boron complex fiber material hardness is very high, and is very big to evil glaze wearing and tearing.The 3rd, the various material expansion coefficient differences of composite are very big, because the difference of ambient temperature is directed at expanding with heat and contract with cold of material, the difficulty to production technology increases like this.And present the quality shakiness.

Chinese patent CN1073607A discloses that a kind of ' electrotherapeutic toothbrush ' it provides a kind of conductive bristle simple for production, bristle arrange in a variety of forms and when brushing teeth dental bed and tooth can place fully in the electric field scope that is produced between this conductive bristle, with the electrotherapeutic toothbrush of the different-effect that plays prevention and treatment oral disease.But this electrotherapeutic toothbrush has following deficiency: the one, forgotten that electrotherapeutic toothbrush will be this with the treatment, and it exactly omits the marrow of CN1040918A, how treatment.The 2nd, its conductive bristle is with two groups of nickel--the chromium silk is formed, and the two hardness is all very high, and is very big to the dentium nitor wearing and tearing.The 3rd, nickel, chromium all are heavy metals, all are poisonous lewis' acids in electric field or under the wearing and tearing.Harm to organism is very big.Obviously the inventor is not the insider.

The objective of the invention is provides a kind of special electrode coating (hereinafter to be referred as cathod coating) that simply contains series of rare earth element and trace element of making to substitute conductive bristle in order to solve above-mentioned technical deficiency, thoroughly solved the wear problem of conductive bristle to dentium nitor, and inherited the marrow of CN1040918A patent, this in addition special coating also contains a certain amount of trace element such as boron, calcium, manganese, molybdenum, zinc, copper, cobalt, vanadium, chromium, cadmium, nickel, barium, antimony, stannum, selenium, Deng 25 kinds of elements that organism is required, also solved simultaneously under certain electric field intensity, can discharge the technical know-how of a certain amount of trace element selectively, for example trace element--the normal contents of copper in organism is in 32--100PPM (microunit 1PPM=1 * 10 ^-6Gram), promptly present the crisp symptom of skeleton (comprising dentale), but when surpassing 100PPM, understand trace element equally and poison if be lower than 32PPM--also can present the crisp or crisp phenomenon of dentale of skeleton.The present invention discharges selectively, in other words, when oral cavity copper content is lower than 32PPM, its meeting copper ion releasing and dentale carry out ion exchange or oral mucosa absorbs, but when copper content surpasses 100PPM or during near 100PPM, it can not carry out Copper Ion Exchange with dentale again or be attached to Ya Biao and brushed by toothbrush.The present invention does not just pay effect like this, and in other words it can not only efficient medical odontopathy, oral pathology, and can make the articles for daily use that keep healthy, the generation of preventing tooth diseases oral pathology in advance.

In order to achieve the above object, the present invention is design like this: description of drawings, cathod coating [1] coated on arbitrary metallic conductor surface as negative electrode, by conductive adhesive [10] or directly be connected with the negative pole of battery [3], and the positive pole of battery [3] links by the negative pole of reed [4] with battery [9], and the positive pole of battery [9] links to each other with positive plate [6] again.Except that cathod coating [1] and positive plate [6] are contained in arbitrary relevant position of brush [7], all the other all are sealed in brush [7] the inside by bonnet [5], put brush holder [8] to strengthen feel.So just, become the open circuit loop.When brushing teeth, saliva or just served as automatic interrupter for the specially designed toothpaste of medical toothbrush.Having made into closed circuit loop makes the present invention bring into play medical function.

Saliva is an electrolyte, but weak electrolyte,--its component of tooth reinforcing agent is: methylcellulose---250 grams for the medical function inventor that can bring into play medical toothbrush has to greatest extent designed a kind of toothpaste especially, 12-alkanol sodium sulfate--750 grams, spice--200CC.White sugar--850 grams, sodium fluoride--450 grams.Distilled water 3000CC.Above-mentioned mixed body is a transparent colloid.

Commodity of the present invention king by name god in age brush.Trade mark is a WL board description of drawings: [1] special electrode material coating (negative electrode) [2] bristle [3] battery [4] reed [5] bonnet [6] anode [7] brush [8] brush holder [9] battery [10] conductive adhesive
