Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    This invention relates to a device for cleaning the tongue of the user wherein the device combines mechanical scraping of the tongue with the spray action of a liquid, preferably water and possibly water with a chemical additive. When operated, this tongue cleaning device should reduce the amount of odorous bacteria located at the surface and in the papillac of the tongue.  
           [0003]    2. Brief Description of the Prior Art  
           [0004]    In the prior art, it is well known that halitosis or bad breathe is caused by a buildup of bacteria in the mouth where there is an emission of hydrogen sulfide and sulfide methlmercaptan from these bacteria. These bacteria are needed because they assist the digestion process. However, for some persons, these particular bacteria are found in higher numbers causing noticeable cases of halitosis or bad breath. Instances of these noticeable cases of bad breath are evenly split between men and women. The bacteria of the condition known as Halitosis, are classified as anaerobics meaning that these bacteria grow in an area where oxygen is not present. For the tongue, this area is not exclusively on the surface of the tongue but is mostly between the papillac that make up the body of the human tongue.  
           [0005]    Various devices exist that attempt the elimination of the bacteria which causes Halitosis. In U.S. Pat., Des. 267,508 a tongue cleaning device is disclosed with a depiction of tongue scraper. The tongue scraper has an edge which is run over the surface of the tongue in a scraping motion. This scraping eliminates a minimal amount of bacteria since most bacteria grow beneath the surface in the papillac of the tongue. Since scraping the tongue alone is inadequate, continued scraping for effect without noticeable results could lead to soreness or even bleeding on the tongue.  
           [0006]    Other methods for treating Halitosis include brushing the teeth and using dental floss on the teeth; the use of antibiotics; the application of oral rinses to the tongue; and treatments which convert the bacteria into non-odorous forms. Brushing teeth and using dental floss on the teeth are usually inadequate methods to rid the mouth of such bacteria, because the build-up is located on the tongue and not the teeth. Antibiotics have only a temporary effect of eliminating all bacteria but since the bacteria are beneficial, the body will produce more bacteria of possibly resistant strains to replace the eliminated bacteria. The resistant strains could eventually be impervious to the continued use of antibiotics and the problem of over-produced bacteria will return. Also, continued use of antibiotics may lead to infections, in which the infections result from an imbalance of normal oral bacterial levels. Oral rinses which pass the tongue, effect the surface of the tongue and only incidentally reach the papillac of the tongue if at all. Treatments which convert bacteria into non-odorous forms can be lengthy and may require clinical observance which can lead to expense.  
           [0007]    It is seen from the foregoing that there is a need for a device which overcomes the disadvantages found in the prior art concerning the reduction of buildup of odorous bacteria on the surface and in the body of the tongue. Such as device should be able to reduce in an effective and less costly manner; the amount of bacteria buildup on the surface of the tongue and in between the papillac which make up the body of the tongue.  
         SUMMARY OF THE INVENTION  
         [0008]    It is therefore an object of the present invention to provide a device which reliably removes bacteria buildup in between the papillac of the tongue.  
           [0009]    It is therefore a further object of the present invention to provide a device which reliably removes bacteria buildup on the surface of the tongue.  
           [0010]    It is therefore a still further object of the present invention to provide a device for removing bacteria buildup on the surface of the tongue and in the papillac of the tongue in which the device can be disassembled for cleaning.  
           [0011]    It is therefore a still further object of the present invention to provide a device for removing bacteria buildup on the surface of the tongue and in the papillac of the tongue in which the device can be disassembled for changing worn out or broken components.  
           [0012]    It is therefore a still further object of the present invention to provide a device which is portable in size.  
           [0013]    To attain the objects described, there is provided a device which is a mechanical scraper having a sprayer with a nozzle. This sprayer can draw on a water source that has effective chemical additives such as chlorine dioxide. The device achieves the best results when attached with an oral irrigator that can provide pressurized liquid for high energy spraying. High energy spraying would enhance the ability to reach the papillac of the tongue.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0019]    Referring now to the drawings wherein like numerals refer to like elements throughout the several views, one sees that FIG. 1 is a bottom cross-sectional view of the tongue cleaner  10  of the present invention. The tongue cleaner  10  is generally a housing  12  shaped to be grasped by the user to allow the user to grip and manipulate during tongue cleaning. The shape of housing  12  is an elongated rounded body with varying circumferences.  
         [0020]    An mouthpiece  14  is located on the distal end and integral with housing  12 . From the mouthpiece  14 , the circumference of the housing  12  decreases to a gripping area  16 , which is a majority of the outside surface area of the housing  12 . From the gripping area  16 , the housing  12  increases to a slightly larger circumference at the liquid source attachment section  18 . The enlarged circumference of liquid source attachment section  18  allows an oral irrigator to conformably fit to the tongue cleaner  10 . At the liquid source attachment section  18 , two mating prongs  20 , 22  and a liquid source extension  24  are also provided for the fit of an oral irrigator.  
         [0021]    When the tongue cleaner  10  is being used, the housing  12  is pulled in a lateral motion on the surface of the tongue of the user as indicated by direction arrow  17  in FIG. 2. Upon simultaneous activation of the oral irrigator, pressurized liquid emits from a spray nozzle as indicated by spray pattern  19 . These two concurrent actions expose the surface and the papillac of the tongue to the cleansing action of the pressurized liquid thereby reducing the amount of anaerobic bacteria residing in these areas.  
         [0022]    In FIG. 1, mouthpiece  14  is an semi-elliptical housing whose longitudinal axis  26  is perpendicular to the longitudinal axis  28  of the housing  12 . The mouthpiece  14  is rounded at its boundaries for comfortable movement within the mouth of the user. The width of mouthpiece  14  is sized for fitting within the mouth of the user. The mouthpiece  12  also allows detachment of the scraper section  15  for cleaning and replacement of parts. Recess  30  located on the underside of mouthpiece  14  and along longitudinal axis  26 , is provided to allow insertion of scraper section  15 . Located near recess  30  and towards gripping area  16  is spray port  32 .  
         [0023]    Integral to spray port  32  is spray nozzle  34 . In FIG. 2, spray nozzle  34  is sized to produce microfractionated jets of pressurized liquid with a pulsation frequency between 1500 and 6000 pulsations per minute and a spraying surface of 0.5-4 square millimeters when the internal integrated pressure is between 1 and 6 bars. The spray pattern  19  of microfractionated jets would emit from spray nozzle  34 . Pressurized liquid, needed for the spray pattern  19 , may be water with or without chemical additive supplied through liquid channel  38 . Liquid channel  38  is a hollowed section interior to housing  12  and following the longitudinal axis  28  of housing  12 . Pressured water to liquid channel  38  is supplied by liquid source extension  24 , when liquid source attachment section  18  is coupled with an external liquid source.  
         [0024]    Liquid source attachment section  18  preferably couples with a “Broxo-Jet” or “Broxototal” oral irrigator manufactured by Les Produits Associates of Geneva Switzerland, herein incorporated by reference. Alternative liquid sources suitable for the purpose of providing pressurized liquid to the present invention may be used. When provided with the “Broxo-Jet” or “Broxototal” oral irrigators, spray nozzle  34  produces micro-fractioned jets with a pulsated frequency between 1500 and 5000 pulsations/minute, an internal integrated pressure between 1 and 6 bars and spraying surface between 0.5 and 4 square millimeters.  
         [0025]    In FIG. 1, prongs  20 ,  22  are integral with and extrude from liquid attachment section  18  as flexible lengths for attachment to an oral irrigator. The flexibility of prongs  20 ,  22  allow them to be squeezed to fit into corresponding apertures on an oral irrigator and when placed prongs  20 ,  22  snap back to their original position securing the oral irrigator. The direction of flexibility of prongs  20 ,  22  is indicated by arrows  40 . Liquid source extension  24  is a hollowed cylinder used as an additional attachment section to fit with the liquid orifice of an oral irrigator.  
         [0026]    In FIG. 3 the attachment of scraper section  15  is shown, where the figure depicts a cross-sectional end view of mouthpiece  14  of tongue cleaner  10 , looking away from housing  12 . Mouthpiece  14  has recessed areas  44 ,  46  sized to accommodate attachment fixtures  48 ,  50  of scraper section  15 . In FIG. 4 the shape of scraper  49  is depicted which is an end view of mouthpiece  14  looking towards housing  12  with scraper  49  of scraper section  15  depicted. Scraper  49  is a thickened blade having sides edges  51 ,  52 ; opposite faces  54 , ( 56  in FIG. 2); and an edge  58 . Scraper  49  has a width of twenty millimeters plus or minus 50% in the direction of axis  26 . Edge  58  and side edges  51 ,  52  which are in contact with the tongue of the user are flat or have radius not smaller than 50 millimeters. Scraper  49  is preferably made of plated gold however alternatives suitable for the purpose of the present invention may be used.  
         [0027]    Thus by the present invention its objects and advantages are realized and although preferred embodiments have been disclosed and described in detail herein, its scope should be determined by that of the appended claims.
