FIG. 1 shows a block diagram of an overview of an antibacterial dental floss device of one embodiment of the present invention. FIG. 1 shows an antibacterial dental floss device 100 that can be assembled in a compact case 110. The antibacterial dental floss device 100 can be configured with a bobbin 120 which is used to hold a length of a dental floss 125. When a user pulls out a short length of the dental floss 125 from the bobbin 120 it passes over a series of curved guide pins 132 and pulleys 134. The dental floss 125 is routed through a dental floss fraying processor 130 which cuts and frays short sections of a portion of the fibers from which the dental floss 125 is manufactured of one embodiment of the present invention.
The dental floss fraying processor 130 uses electrical power supplied from a battery pack 180 to heat thermal devices to fuse the fibers being cut at a short distance on both sides of the point where the cut is made. Dental floss threads are manufactured in various thicknesses from materials such as polyester, nylon, PTFE and Polymer. These materials can be heated to allow thermal bonding of the fibers to one another. This prevents the cut fibers from being pulled from the floss thread while flossing. The dental floss fraying processor 130 then brushes the cut fibers to create bristles of one embodiment of the present invention.
The bristled dental floss 125 is passed through a oral antibacterial compound reservoir 140 and coated with an oral antibacterial compound, for example antibacterial tooth paste, an all natural ingredient oral antibacterial compound, plaque inhibiting antibacterial compound and antibacterial compounds that contain vitamins. The oral antibacterial compound reservoir 140 can be filled or refilled using a fill tube 145. The user can use a cut off 160 to cut the desired length of bristled dental floss coated with an oral antibacterial compound pulled from the antibacterial dental floss device 100. The user can then apply the antibacterial compound to the teeth and gums while using the bristled floss to remove food particles and brush the tooth surfaces between the narrow spaces that would be difficult to reach with a toothbrush. This will facilitate the removal of plaque and other build up of one embodiment of the present invention.
Once completed with flossing the user can switch on an ultraviolet light lamp 170 built into the antibacterial dental floss device 100 and powered by a battery pack 180. The user will direct the ultraviolet light radiating through the exterior lens 175 of the antibacterial dental floss device 100 to areas inside the mouth including the gums and palate. The germicidal benefits of ultraviolet light will further reduce oral infections. Gum disease can result from bacterial plaque building up between teeth, under the gum line and around dental appliances. The antibacterial dental floss device 100 provides enhanced bristled flossing to better clean the space between teeth, applies an antibacterial compound to the area between teeth, under the gum line and around dental appliances combined with ultraviolet light as an additional germicidal treatment. The antibacterial dental floss device 100 helps fight gum diseases, helps reduce plaque buildup and provides the user with access to advanced oral hygiene treatments in a compact portable device of one embodiment of the present invention.
Detailed Operation:
The foregoing has described the principles, embodiments and modes of operation of the present invention. However, the invention should not be construed as being limited to the particular embodiments discussed. The above described embodiments should be regarded as illustrative rather than restrictive, and it should be appreciated that variations may be made in those embodiments by workers skilled in the art without departing from the scope of the present invention as defined by the following claims.
FIG. 2 shows a block diagram of an overview flow chart of an antibacterial dental floss device of one embodiment of the present invention. FIG. 2 shows the antibacterial dental floss device 100 in the case 110 that can be manufactured from materials for example plastic. The bobbin 120 is installed on a spindle 210 to allow spooled dental floss 200 to play off the bobbin 120 when pulled by the user. The unwinding dental floss 125 enters the dental floss fraying processor 130. The dental floss fraying processor 130 can be configured with one or more fraying cutter module 230 to cut the outer layers of fibers of the floss thread. The cutting blades 136 of the fraying cutter module 230 can be configured to be attached in the inner curved area of a pulley channel 138 as a crescent shaped blade to allow radial cuts of one embodiment of the present invention.
The dental floss fraying processor 130 can be configured with one or more thermal bonding module 240 to fuse fibers a short distance on both sides of the cut. The thermal bonding module 240 is heated by a thermal bonding electrical circuit 250 passing through the thermal bonding module 240 components that are sized to produce resistance to the electrical current and heat sufficiently to fuse the fiber material. The heated-elements 139 of the thermal bonding module can be configured to be attached in the inner curved area of a pulley channel 138 in a crescent shape to allow radial fusing. The thermal bonding electrical circuit 250 draws electricity from one or more battery 260 installed in the battery pack 180 of one embodiment of the present invention.
The fused cuts produce a frayed dental floss 270 that is routed through a bristle brush module 272. The bristle brush module 272 combs the cut fibers away for the main floss thread to produce a bristled dental floss 274. The bristled dental floss 274 enters the oral antibacterial compound reservoir 140 and bathes the bristled dental floss 274 in an antibacterial compound 275 of one embodiment of the present invention. The antibacterial compound 275 is placed in the oral antibacterial compound reservoir 140 using the fill tube 145. The antibacterial compound 275 can be configured for example as a liquid, gel or paste and can be an over the counter product or prescription medication. The bristled dental floss 274 becomes coated or soaked in the antibacterial compound 275 before being separated using the cut off 160. The antibacterial coated bristled dental floss 280 is now available for the user to floss their teeth using the bristled dental floss 274 to brush in between teeth and reach the area of the teeth and gums not accessible with a tooth brush. This allows the user to remove plaque and other build up not just food particles while flossing. The antibacterial compound 275 will be applied to those same hard to reach areas where bacteria and other materials or organisms generally start gum diseases and plaque buildup of one embodiment of the present invention.
The user can treat the oral cavity in its entirety using the ultraviolet light lamp 170 built into the antibacterial dental floss device 100. The user can push a switch button to open an ultraviolet light switched electrical circuit 248 to conduct electricity from one or more battery 260 in the battery pack 180. The electricity through the ultraviolet light switched electrical circuit 248 will power up the ultraviolet light lamp 170. The ultraviolet light lamp 170 will radiate ultraviolet light through the lens 175 into the oral cavity as directed by the user. The benefits of the germicidal ultraviolet light illumination will aid in combating bacteria and other organisms in areas not normally contacted in brushing or flossing for example the roof of the mouth, rear inner cheek tissues and under the tongue. The antibacterial dental floss device 100 can be configured to include an AC current adapter plug-in to allow rechargeable batteries to be installed in the battery pack 180 of one embodiment of the present invention.
The ability of the antibacterial dental floss device 100 to fill prescribed medication into the oral antibacterial compound reservoir 140 provides dentist and other oral specialist the opportunity to effectively treat patients in an outpatient mode. The outpatient can effectively administer those prescribed medications using the same familiar techniques of flossing and save expensive treatment visits to the dental office. The compact portable antibacterial dental floss device 100 can enable a user to easily enhance their preventative oral hygiene to reduce gum disease and bacterial plaque build-up of one embodiment of the present invention.
