This invention is generally related to hygienic, therapeutic, and medical care methods, devices, and applications.
The medical benefits of far-infrared radiation on the living body have been known for a long time, and therefore, there are far-infrared devices on the market for improving human and animal health. Most of these devices produce far-infrared radiation by using ceramic materials. In order to generate far-infrared radiation at intensities suitable for therapy or sterilization, the ceramic materials must be heated to high temperatures, sometimes few hundred degrees C. This limits the use of existing far-infrared devices in many hygienic-therapeutic applications, for example, using them for dental oral care or hair care to kill bacteria and microbes, and to rejuvenate teeth, gums and hair. In addition, the generation of far-infrared radiation in these devices is not energy-efficient; efficiencies typically are only a few percent or less. Therefore, there exists a strong need for hygienic-therapeutic far-infrared devices which will produce intense far-infrared radiation with high efficiency, and would operate at relatively low temperatures.
The devices with ceramic far-infrared radiation sources might also cause some health problems. Most of the ceramics are made from powder or clay and during their use, the ceramic materials can chip off (erode) from the surface and can be inhaled by the living body. Therefore, there is a great need for intense infrared radiation sources that are more environmentally safe and do not expose humans or animals to health risks.
Another limitation of the devices with ceramic far-infrared radiation sources is fixed radiation spectra which cannot be changed to increase the effectiveness of therapy. The living body is most influenced by infrared radiation within the wavelength range of 8 to 12 microns and many currently used devices cannot deliver radiation at this spectral range.
To mitigate the previously stated issues of using ceramics as far-infrared sources in hygienic-therapeutic devices, this invention proposes to use novel conductive sources emitting intense far-infrared radiation with a high conversion efficiency of energy to radiation, typically greater than 90%. In nature, conductive materials follow the “black body” radiation phenomenon and they do not emit intense far-infrared radiation. However, there are some conductive materials, like carbon fiber and other materials proposed in this invention, which emit very intense far-infrared radiation with extremely high conversion efficiencies of energy to radiation.
The invention discloses novel hygienic-therapeutic or personal care devices that are based upon intense far-infrared sources where radiation is generated by novel conductive materials. The proposed conductive materials do not follow the Wien's law (“black body” law), i.e. the materials in a wide range of temperatures have a few orders of magnitude more intense infrared radiation than typical conductive materials. In addition, the far-infrared sources generate radiation with very high efficiency, typically greater than 90%.
The scope of the invention includes, for example, far-infrared hygienic-therapeutic/personal care devices selected from the group consisting of: toothbrush, hairbrush, hair dryer, hair straightener, comb, elastic bandage, pad, pain-reliever device, body massager, hygienic therapeutic illuminator, and other far-infrared hygienic-therapeutic/personal care devices.
All patents, patent applications, and literature cited or referenced in this description are incorporated herein by reference in their entireties. In the case of inconsistencies, the present disclosure, including definitions and usage, will control.
The disclosure generally describes novel hygienic-therapeutic or personal care devices that are based upon intense far-infrared sources in which radiation is generated by novel conductive materials 101. The conductive materials are specially designed and made to radiate ten to thousands times stronger far-infrared radiation than typical conductive materials 100, and such strong far-infrared radiation is achieved with high, typically greater than 90%, conversion efficiency of energy to radiation. The radiation properties of the proposed conductive materials do not follow the Wien's law (“black body” law) as is shown in
It should be understood that the figures illustrate certain components (i.e., conductive source 101, dielectric-ceramic source 102, electric heater 103, power supply 104) as contained within housing 110. In alternative embodiments, however, these components maybe partially or wholly external to the particular devices. For example electronics 106, a computer or processor 107 and a power supply 104 maybe partially or wholly external to the housing 110 on the bandage as illustrated in
The scope of the invention includes, for example, far-infrared hygienic-therapeutic/personal care devices selected from the group consisting of: toothbrush, hairbrush, hair dryer, hair straightener, comb, elastic bandage, pad, pain-reliever device, body massager, hygienic therapeutic illuminator, and other far-infrared hygienic-therapeutic/personal care devices. Examples of the devices are illustrated in
In an embodiment, the invention considers the use of the novel conductive materials which emit high intensity far-infrared radiation. The conductive material, for example, a carbon fiber made as a wire 101, is placed in a toothbrush head and connected to a toothbrush battery 104 as is shown in
The scope of the invention includes far-infrared sources made of the novel conductive materials selected from the group of: super conductive, conductive, or semiconductive. These materials emit far-infrared radiation at intensities much higher, usually ten to thousands times higher, than is predicted by the Wien's law (“black body” law). In addition, these materials produce this radiation with very high efficiency.
Another embodiment of the invention considers delivering electric energy to the radiation source 101 in different modes: DC (direct current), AC (alternative current), frequency, or pulse. The use of the single mode or the plurality modes in the device allows tuning the far-infrared radiation of the device according to body properties and hygienic-therapeutic needs.
Although the invention has been explained in relation to its preferred embodiment as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
This application claims the benefit of U.S. Provisional Application Ser. No. 60/846,879 filed Sep. 25, 2006, entitled “Conductive Far-Infrared Devices”, which is incorporated by reference.
