Embodiment describes in detail
All publication, patents and patent applications of quoting herein are incorporated herein by reference.The present invention relates to oral care appliance, this device has the size that is applicable to the oral cavity.In one embodiment, this device has the size that is fit to be close to many teeth settings.This oral care appliance in conjunction with a kind of respond the voltage that applies produce the acoustic emitter of pressure pulse.Term used herein " sound " be meant can hear, sound wave or ultrasound wave or vibration.Device of the present invention is used in combination with the oral care substance that contains oral care active agents.Oral care active agents can be any active substance that beneficial effect can be provided tooth or soft tissue.Oral care substance at first can be administered on the device, and then be administered on tooth or the soft tissue, perhaps oral care substance at first can be administered on tooth or the soft tissue, and then device is administered on the oral care substance.Be not bound by theory, it is believed that the concentration on the border of the renewable oral care active agents of acoustic energy or pressure pulse between oral care substance and tooth or tissue surface, this can guarantee the Cmax gradient, diffuses into dental surface and/or surface contact therewith to order about oral care active agents.
With reference to figure 1, oral care appliance constructed in accordance 10 is described now.This oral care appliance 10 comprises acoustic emitter 12 and with this acoustic emitter 12 voltage source of electrical communication is arranged.Voltage source can provide acoustic emitter 12 as required and exchange or unidirectional current.Oral care appliance 10 can further comprise the voltage source of one or more battery 13 forms, perhaps can be connected to the external power source (not shown), as the AC power supplies socket.Oral care appliance 10 has the handle 14 that comprises near-end 16, and acoustic emitter 12 near or be provided with at the far-end 18 of handle 14, this far-end 18 is relative with near-end 16.Acoustic emitter 12 can provide in shell at far-end 18.For starting oral care appliance 10, can on handle, provide switch 22.Acoustic emitter 12 can provide in a variety of forms.For example, acoustic emitter 12 can be used as piezoelectric transducer or magnetic resistance (magnetorestrictive) transducer provides.Piezoelectric transducer can comprise piezopolymer, as polyvinylidene fluoride (PVDF) polymer or copolymer, or comprises the piezoelectric ceramics that produces acoustic energy output.Piezopolymer can provide by form of film.For being reduced to the input of the required power of transducer, available transducer excites another frame for movement with the specific natural frequency compatible with oral care substance, as in addition second piezoelectric membrane.
Acoustic emitter can be greater than about 20KHz, or greater than about 50KHz, or greater than about 100KHz, or greater than about 250KHz, or greater than about 500KHz, or greater than about 1000KHz, and/or less than about 5MHz, or less than about 2MHz, or less than about 1MHz, or less than the frequency work of about 500KHz.When oral care active agents was brightener for tooth such as hydrogen peroxide, preferred frequency range can be about 20KHz to about 500kHz.
Shell 20 has emitting surface 24, and this surface has a certain size part with the front surface that covers one or many teeth.Emitting surface 24 can form the part of acoustic emitter 12 or can be the independent frame for movement that can be excited by acoustic emitter 12, as previously described.In other words, but emitting surface 24 acoustics are coupled to acoustic emitter 12, so that the vibration of acoustic emitter induced vibration in emitting surface 24.In addition, emitting surface 24 can mechanical coupling and acoustics be coupled to acoustic emitter 12, under the situation as the part that forms transducer at it.Emitting surface 24 can have between about 0.5cm
2With about 7cm
2Between or between about 1cm
2With about 5cm
2Between surface area.In one embodiment, emitting surface provides as the smooth surface of not giving prominence to structure.The electric toothbrush form with bristle or layers of brush bristles that oral care appliance 10 can also surround or partly surround emitting surface 24 provides.During use, emitting surface 24 is contacted with oral care composition place greater than about 1 minute, or greater than about 2 minutes, or greater than about 3 minutes, or greater than about 4 minutes, or greater than about 5 minutes, or greater than about 10 minutes, and/or less than about 30 minutes, or less than about 15 minutes, or less than about 10 minutes, or less than about 5 minutes time.In one embodiment, emitting surface has less than about 2W/cm
2, or less than about 1W/cm
2, or less than about 0.5W/cm
2, and/or greater than 0.1W/cm
2, or greater than about 0.25W/cm
2, or greater than about 0.5W/cm
2Sound intensity output.
During use, oral care appliance 10 is moved at the front teeth near surface of maxillary or mandibular arch.Though emitting surface 24 has been used as the contact oral care substance and has described, emitting surface 24 can contact other surface of inserting between oral care substance and the emitting surface 24 also within imagination scope of the present invention.For example, emitting surface 24 can be close to paster surface and be provided with, and this paster surface has the oral care substance that is administered to this material piece opposition side, as shown in Figure 2, so that the acoustic energy of emitting surface 24 is delivered to oral care substance by this material piece.The example that is suitable for paster and oral care substance is set forth in United States Patent (USP) 5,891,453 and 6,136,297.
With reference to figure 3, Fig. 3 is with form diagram another oral care appliance of the present invention of arc dens supporter 122 and acoustic emitter 12.This dens supporter has a certain size to cover a plurality of teeth of maxillary and/or mandibular arch.Dens supporter 122 has first groove or the passage 124 that can insert at least a portion maxillary.Can provide the second channel (not shown) to be used to receive at least some teeth of mandibular arch at the reverse side of first passage 124.First passage 124 has during use the inner surface 126 with the front teeth adjacent setting in surface of maxillary.Dens supporter 122 can be solid or hollow or its combination.If dens supporter 122 is hollow, then can be filled with liquid or gas, be delivered to inner surface 126 with the acoustic energy that helps acoustic emitter 12 by dens supporter 122.During use with the dens supporter 122 of the adjacent setting of tooth front surface within surface 126 can be thinner, or provide as the material layer different with dens supporter 122 remainders, so that inner surface 126 can be used to make the acoustic energy of microphone 12 to be delivered to the oral care composition that is arranged in the dens supporter 122 as barrier film.Microphone 12 is attached on the dens supporter 122, so makes its machinery or acoustics be coupled to inner surface 126, inner surface 126 is used for the acoustic energy that acoustic emitter 12 is produced as emitting surface.If desired, a plurality of acoustic emitters 12 are attached on the dens supporter 122.
