DESCRIPTION OF A PREFERRED EMBODIMENT

A tongue deodorizing device 10 is depicted in FIG. 1 and comprises a tongue contacting instrument 12 and a water or fluid supply 14 removably connectable to the tongue contacting instrument 12. The tongue contacting instrument 12, as best shown in FIGS. 1-6, comprises a tongue contacting member 16 and a handle 18 connected to the tongue contacting member 16. The tongue contacting member 16 has a distal or forward end 20 and has a proximal or rearward end 22 spaced longitudinally from the forward end 20. The forward end 20 defines a distal or forward end of the tongue contacting instrument 12. The rearward end 22 is connected with the handle 18. The tongue contacting member 16 is bisected lengthwise or longitudinally by a longitudinal plane P1 containing a central longitudinal axis X of the handle 18. The central longitudinal axis X is also the central longitudinal axis of the tongue contacting instrument 12, and the entire instrument 12 is bisected longitudinally by the longitudinal plane P1. The tongue contacting member 16 has a length or longitudinal dimension in the longitudinal plane P1 and has a width or lateral dimension perpendicular to its length and to the longitudinal plane P1. The tongue contacting member 16 comprises at least one tongue contacting side or face 24 and, preferably, comprises opposed tongue contacting sides or faces 24 and 26. The tongue contacting side 24 may be considered a first tongue contacting side and comprises a stainless steel tongue rubbing surface 28 for being rubbed against the surface of the tongue. The tongue contacting side 26 may be considered a second tongue contacting side and comprises a tongue scraping element 30 for scraping the surface of the tongue and a debris collecting surface 32 bordered by the tongue scraping element 30 for collecting debris scraped from the surface of the tongue by the tongue scraping element 30. The tongue scraping element 30 extends continuously and without interruption from one lateral side of rearward end 22 to the opposite lateral side of rearward end 22.

The tongue rubbing surface 28 is a smooth, solid surface bordered or bounded by the tongue scraping element 30. The tongue rubbing surface 28 extends in the longitudinal direction between the forward and rearward ends 20 and 22, and extends in the lateral direction perpendicular to the longitudinal direction. The tongue rubbing surface 28 is preferably continuously curving with a convex curvature in the lengthwise or longitudinal direction, and with a convex curvature in the widthwise or lateral direction. The configuration of the tongue rubbing surface 28 may be considered similar to the exterior surface configuration of a dome or bowl. As depicted in FIG. 3, the longitudinal convex curvature of the tongue rubbing surface 28 may be somewhat asymmetrical, having a steeper or more pronounced convex curvature extending distally from rearward end 22 and having a more gradual or less steep convex curvature extending proximally from distal end 20. The tongue rubbing surface 28 may thusly be composed of surface segments of different radii of curvature. For example, the longitudinal convex curvature of the tongue rubbing surface 28 may have a proximal radius of curvature extending distally from rearward end 22 and may have a distal radius of curvature, greater than the proximal radius of curvature, extending proximally from distal end 20. Thus, the elevation of the tongue rubbing surface 28 from the tongue scraping element 30 in the longitudinal direction may increase more gradually in the proximal direction from distal end 20 than the elevational increase in the distal direction from rearward end 22. It should be appreciated, however, that the tongue rubbing surface 28 can have a symmetrical longitudinal convex curvature. The lateral convex curvature of the tongue rubbing surface 28 may be symmetrical on each side of plane P1 as shown in FIGS. 5 and 6. The configuration of the tongue rubbing surface 28 is advantageous for establishing close contact with the surface of the tongue. When the tongue rubbing surface 28 is pressed against and rubbed along the surface of the tongue, the tongue will deformably conform or substantially deformably conform to the configuration of the tongue rubbing surface to establish close contact with at least a substantial portion of the tongue rubbing surface.

The tongue scraping element 30 extends along the perimeter of the tongue contacting member 16 and is preferably continuously curving between the lateral sides of rearward end 22. The tongue scraping element 30 may follow a substantially elliptical, ovoid or oblong configuration or path between the lateral sides of rearward end 22. Accordingly, the length of the tongue contacting member 16 along the longitudinal plane P1 may be greater than the maximum width of the tongue contacting member 16 perpendicular to the longitudinal plane P1. The forward end 20 of the tongue contacting member 16 is located along the tongue scraping element 30 in alignment with the longitudinal plane P1. The tongue scraping element 30 comprises one or more tongue scraping edges and/or tongue scraping surfaces for scraping the surface of the tongue. The tongue scraping element 30 comprises a tongue scraping surface 34 of narrow width connecting the tongue rubbing surface 28 to the debris collecting surface 32, and a tongue scraping edge 35 formed by the juncture of tongue scraping surface 34 with the debris collecting surface 32. The tongue scraping edge 35 is disposed in a lateral plane P2, perpendicular to the longitudinal plane P1, except for rearward end segments of the tongue scraping edge 35 which curve angularly from the lateral plane P2. As best depicted in FIGS. 3 and 5, the lateral plane P2 containing the tongue scraping edge 35 is offset from the central longitudinal axis X in parallel relation therewith. The direction in which the tongue rubbing surface 28 is elevated from the lateral plane P2 and from the tongue scraping element 30 is perpendicular to the lateral plane P2. Both the tongue scraping surface 34 and the tongue scraping edge 35 can be used to scrape the surface of the tongue to remove material therefrom, but the angled corner formed at edge 35 will be most advantageous for removing adherent material from the surface of the tongue.

The debris collecting surface 32 is a smooth, solid surface bounded or bordered by the tongue scraping edge 35. The debris collecting surface 32 preferably has a concave curvature that follows the convex curvature of the tongue rubbing surface 28. Accordingly, the debris collecting surface 32 may have a longitudinal concave curvature that follows the longitudinal convex curvature of the tongue rubbing surface 28, and the debris collecting surface 32 may have a lateral concave curvature that follows the lateral convex curvature of the tongue rubbing surface 28. The configuration of the debris collecting surface 32 may thusly be considered similar to the interior surface of a dome or bowl. The debris collecting surface 32 defines a debris collecting cavity, depression or recess 36 bordered or bounded by the tongue scraping edge 35.

The rearward end 22 of the tongue contacting member 16 comprises a neck 37 that tapers proximally in width between its lateral sides to connect with handle 18. The neck 37 also curves angularly from the lateral plane P2 to connect with the handle 18, which establishes the parallel offset between the lateral plane P2 of the tongue scraping edge 35 and the central longitudinal axis X of the handle 18. The configuration of the neck 37 provides a smooth tapered transition between the tongue contacting member 16 and the handle 18. The tongue scraping element 30, including the tongue scraping surface 34 and the tongue scraping edge 35, may extend along the neck 37 but these portions or segments of the tongue scraping element 30 will not generally be used to scrape the tongue. Rather, the portion of the tongue scraping element 30 that lies in or along the lateral plane P2 will in general be used to scrape the tongue.

The handle 18 includes a handle body having a distal or forward end joined to the rearward end 22 or neck 37 of the tongue contacting member 16 and having a rearward or proximal end 38 defining a rearward or proximal end of the tongue contacting instrument 12. A water or fluid transport channel 42 extends within the handle body and has a water or fluid inlet 43 at the proximal end 38 and has a water or fluid outlet 44 adjacent the tongue rubbing surface 28. The proximal end 38 of the handle 18 is removably connectible to the water supply 14 to supply water to the fluid inlet 43. The handle 18 has a handle body comprising a longitudinally elongate outer member 40, the water or fluid transport channel 42 extending along the outer member 40, the water or fluid inlet 43 at the proximal end 38 in communication with the fluid transport channel for receiving water from the water supply 14, and the water or fluid outlet 44 adjacent the tongue rubbing surface 28 for discharging water from the fluid transport channel 42. The outer member 40 has a cylindrical portion 46 coaxial with the central longitudinal axis X and extending distally from a terminal proximal end 48 of the cylindrical portion 46 to an angled or sloping distal extension 50 of the outer member 40. The distal extension 50 extends distally from the cylindrical portion 46 at an angle in close overlapping relation over the rearward end 22 or neck 37 of the tongue contacting member 16 to terminate at a terminal distal end 52 of the outer member 40. The terminal distal end 52 can be rounded, arcuate or blunt and can have a convex curvature. The distal extension 50 can be angled and/or curved to follow or conform to the angle and/or curve of rearward end 22 or neck 37, which extends distally or forwardly from the handle at an angle to the central longitudinal axis X. The fluid outlet 44 is located in the terminal distal end 52 and is disposed over and adjacent the tongue rubbing surface 28 at a location adjacent, near or close to the rearward end 22 or neck 37 such that water discharged from the fluid outlet 44 is caused to flow over at least a substantial portion of the tongue rubbing surface 28. The fluid outlet 44 is preferably centered with respect to the width of the tongue contacting member 16 and, therefore, the fluid outlet 44 can be in longitudinal alignment with the distal end 20 of the tongue contacting member 16 along the longitudinal plane P1. The fluid outlet 44 comprises one or more apertures, slots or holes of any desirable configuration in the terminal distal end 52. The fluid outlet 44 is depicted by way of example as an elongate, slightly curved slot extending in a direction transverse to the longitudinal plane P1.

The fluid outlet 44 is in fluid communication with the fluid transport channel 42, and the fluid transport channel 42 can extend within the outer member 40. Accordingly, the terminal proximal end 48 of the outer member 40 can be an open end serving as the fluid inlet 43 as shown in dotted lines in FIG. 3, and the outer member 40 can be tubular or at least partly hollow to contain the fluid transport channel 42 therein in communication with the open terminal proximal end 48 and with the fluid outlet 44. The open terminal proximal end 48 of outer member 40 can be receivable with a snug friction fit within an end of a conduit of water supply 14 to supply water to the fluid transport channel for discharge from the fluid outlet 44 as explained further below.

It is also possible to design the handle 18 with a handle body that includes an inner member 54 disposed within the outer member 40 as depicted in FIGS. 1-4 and 6. The inner member 54 can extend proximally from the open terminal proximal end 48 of the outer member 40 to an inner member terminal proximal end 56. The proximal extension of the inner member 54 beyond the terminal proximal end 48 of the outer member 40 can be receivable with a snug friction fit within an end of the conduit of water supply 14 to supply water to the fluid transport channel for discharge from the fluid outlet 44 and assist removable connection of the proximal end of the handle 18 to the water supply 14 as discussed further below. The terminal proximal end 56 of the inner member 54 can be an open end serving as the fluid inlet 43, as shown in solid lines in FIG. 3, and the inner member 54 can be tubular or at least partly hollow to contain the fluid transport channel therein in communication with the open terminal proximal end 56 and with the fluid outlet 44. Alternatively, the inner member 54 can have an external or outer dimension sufficiently smaller than the internal or inner dimension of the outer member 40 so that the fluid transport channel 42 is defined by a gap or space between the internal surface of the outer member 40 and the external surface of the inner member 54, which gap or space is placed in communication with the conduit of water supply 14 by reception of the terminal proximal end 48 within an end of the conduit. It should be appreciated that any suitable arrangement providing fluid communication between a fluid inlet at the proximal end of the handle 18 and the fluid outlet 44 in the terminal distal end 52 of the handle can be used as the fluid transport channel 42.

In a representative but not limiting example of a tongue contacting instrument 12, the tongue contacting instrument has an overall length from distal end 20 to the terminal proximal end 56 of or about 6.5 inches and has a maximum width, corresponding to the maximum width of the tongue contacting member 16, of or about 1.31 inches. At least the tongue rubbing surface 28 is made of stainless steel, and it is desirable that at least the tongue contacting member 16 be made in its entirety of stainless steel. Preferably, the entire tongue contacting instrument 12 is made of stainless steel. The tongue contacting member 16 and the handle 18 can be made integrally, unitarily or monolithically as a single part. The tongue contacting member 16 can be made separately from the handle 18 and assembled to the handle in any suitable manner. Where the handle 18 includes an inner member within the outer member, the outer and inner members can be separate components assembled in any suitable manner.

The water supply 14 is depicted in FIG. 1 and comprises a container 58 for holding a quantity of water, a conduit 60 for connecting the container 58 to the fluid inlet 43 of the handle 18, and a flow control mechanism 62 for controlling the flow of water from container 58 to the fluid inlet 43. The container 58 can have any suitable configuration and, preferably, the container 58 has a configuration and size to hold about 6-8 ounces of water. The container 58 can include indicia 63, such as a fill line, indicating the level to which the container must be filled with water to obtain a quantity of water within the container in the range of about 6-8 ounces. The container 58 can be made of transparent material or can be provided with a transparent window allowing the water level in the container to be visualized for alignment of the water level with the indicia 63. A supply orifice or port 64 is provided in a top of the container 58 for supplying plain water to the container from an available water source such as a tap or faucet. A discharge orifice or port 66 is provided in a bottom of the container 58 for discharging or releasing water from the container via gravitational force.

The container 58 is depicted by way of example as comprising a top wall 68, a bottom wall 70 and four side walls 72 connecting the top and bottom walls. The top wall 68 and the bottom wall 70 may have a square peripheral configuration with rounded corners, and the side walls 72 can be arranged to form or meet at rounded corners corresponding to those of the top and bottom walls. The supply orifice 64 includes an aperture in the top wall 68 of any suitable peripheral configuration. The supply orifice 64 may be centered in the top wall 68. The indicia 63 is depicted as a fill line on the side walls 72 extending around the entire periphery of the container. The discharge orifice 66 is formed by a passage extending entirely through a coupling member 76 located in the bottom wall 70. The coupling member 76 includes a sealing disk 78 disposed on or in the bottom wall 70 along the interior side of the container 58 and a stem 80 extending from the sealing disk 78 through the bottom wall 70 to a connector element 82 located exteriorly of the container 58. The discharge orifice 66 extends through the sealing disk 78, the stem 80 and the connector element 82 in a vertical direction and may be centrally located in the bottom wall 70. The connector element 82 can have a truncated conical configuration or any suitable configuration to be removably received within an end of conduit 60 with a snug friction fit. The container 58 can be provided with a handle 84 by which the container can be suspended or hung from an available structure, such as a door knob 86, at an elevation to assist the gravitational discharge of water from the container through the coupling member 76. The handle 84 can have any desirable configuration and is illustrated as a bail having ends attached to the top wall 68. The container 58 can be made of various materials including rigid materials and/or resilient, flexible or deformable materials. Preferably, the configuration of the container and the materials from which it is made facilitate thorough cleaning for reuse. In a representative but not limiting example, the container 58 has a height of or about 3¼ inches, a width of or about 1¾ inches, and a depth of or about 1¾ inches.

The conduit 60 comprises a length of flexible tubing or hose having open ends removably connectible with the proximal end of handle 18 and with the connector element 82 of coupling member 76 and having a lumen extending therethrough. The conduit 60 is of sufficient length to extend from the container 58 to the instrument 12 while allowing the tongue contacting member 16 to be placed in the mouth of the user. It is preferred that the conduit 60 have a tubular wall that is resiliently collapsible or deformable.

The flow control mechanism 62 can be designed in various ways to control the flow of water from container 58 into the fluid transport channel 42 of the tongue contacting instrument 12. The flow control mechanism 62 comprises a clamp 90 mounted on the conduit 60 near the end of the conduit that is to be connected with the coupling member 76. The clamp 90 includes a bracket 92 removably attached on the conduit 60, a clamp arm 94 pivotally connected to an end of the bracket 92 by a hinge 96, and a locking arm 98 extending from an end of the bracket 92 opposite the hinge. The bracket 92 is formed with a recess for retentively receiving the conduit 60 in a removable manner. Although it may be preferable for the bracket 92 to be placed on the conduit 60 near the end of the conduit that is to be connected to the coupling member 76, the bracket 92 can be placed at other locations along the conduit 60 by removable retention of the conduit in the recess of the bracket. The clamp arm 94 is angularly connected to the bracket 92 via the hinge 96 and extends toward the locking arm 98. The clamp arm 94 carries a protuberance 100 that faces toward the conduit 60. The clamp arm 94 has a slot or notch, not visible in FIG. 1, for receiving the locking arm 98 in releasable locking engagement when the clamp 90 is in a closed or clamped position.

The clamp 90 is depicted in FIG. 1 in an open or unclamped position in which the locking arm 98 is not received in the slot in the clamp arm 94 and the protuberance 100 does not press against the conduit 60 in a constricting manner. Accordingly, the lumen through the conduit 60 is not constricted in size and fluid flow through the conduit is not restricted. The clamp 90 is moved from the open position to the closed position by manually pivoting the clamp arm 94 toward the conduit 60 in the direction of the arrow in FIG. 1. Pivotal movement of the clamp arm 94 toward the conduit 60 causes the locking arm 98 to enter the slot in the clamp arm 94 and causes the protuberance 100 to press against and deform the conduit 60 in a constricting manner. The locking arm 98 will be in locking engagement with the clamp arm 94 when the clamp 90 is in the closed position, and the locking engagement between the locking arm 98 and the clamp arm 94 can be obtained through a frictional and/or mechanical interengagement. In the case of clamp 90, the locking arm 98 is provided with a curved configuration to assist frictional retention of the locking arm in the slot of clamp arm 94 when the clamp is in the closed position. In the closed position for clamp 90, the protuberance 100 pressing against the conduit 60 collapses the conduit wall and constricts or closes the lumen of the conduit to restrict or prevent fluid flow past the clamp 90. The clamp 90 can be moved from the closed position to the open position by manually releasing the clamp arm 94 from engagement with the locking arm 98. The clamp 90 can be provided with or made from materials providing a spring bias by which the clamp 90 is normally disposed in or assumes the open position.

When the conduit 60 is connected with the fluid inlet 43 of handle 18 and with the coupling member 76 of container 58 and the clamp 90 is in the open position, water is discharged from the container 58 into the conduit 60 due to gravitational force, and the water flows through the conduit 60 and the fluid transport channel 42 of the tongue contacting instrument 12 for discharge from the fluid outlet 44. The tongue deodorizing device 10 is designed so that the water is discharged from the fluid outlet 44 at a flow rate of or about 0.2 ounce-0.4 ounce per second. Accordingly, a quantity of or about 6-8 ounces of water in container 58 is discharged from the fluid outlet 44 in about 20-30 seconds.

The tongue deodorizing device 10 can be used to accomplish or perform two different modes of tongue deodorization. One mode of tongue deodorization involves a mechanical scraping action performed with the tongue scraping element 30 of the tongue contacting instrument 12. A second mode of tongue deodorization involves a non-mechanical reaction that is caused to occur due to contact of the stainless steel tongue rubbing surface 28 with the tongue in the presence of the flow of water 102 discharged from the fluid outlet 44. The mechanical mode of tongue deodorization can be performed with or without a flow of water provided to the mouth. In addition, it is preferable to perform the mechanical mode of tongue deodorization first, closely followed by performance of the non-mechanical mode of tongue deodorization.

In order to perform the mechanical mode of tongue deodorization, the user manually grasps the handle 18 and manipulates the tongue contacting instrument 12 via the handle to place the tongue scraping element 30 in contact with the tongue, and especially the dorsum of the tongue. The user manipulates the handle 18 to press the tongue scraping element 30 against the tongue while moving it along the surface of the tongue in a scraping action to remove material from the surface of the tongue. Typically, one lateral side of the scraping element 30 will be used to scrape the tongue with the opposite lateral side of the scraping element 30 elevated from the tongue as the tongue contacting member 16 is moved in the direction of the elevated lateral side. It is desirable to contact the dorsum of the tongue with the tongue scraping element 30 as far back or posterior as possible on the tongue, within comfort limits of the user, and to draw the tongue scraping element forwardly or anteriorly along the tongue in a posterior to anterior scraping stroke, but scraping strokes can be performed in any direction along the surface of the tongue. Desirably, the scraping strokes will be repeated numerous times to remove as much material as possible from the tongue and, in particular, the coating on the dorsum of the tongue. Either or both of the tongue scraping surface 34 and the tongue scraping edge 35 can be used to scrape material from the tongue. As the tongue scraping element 30 is moved along the surface of the tongue, material scraped from the tongue by the tongue scraping element is directed toward and collected on the debris collecting surface 32 and in the debris collecting cavity 36. Following the mechanical mode of tongue deodorization or at any time during the mechanical mode of tongue deodorization, debris collected on the debris collecting surface 32 and in the debris collecting cavity 36 can be removed by removing the tongue contacting member 16 from the mouth and rinsing the debris collecting surface and cavity with water. Water can be supplied to the mouth during the mechanical mode of tongue deodorization, and water can be supplied to the mouth using the water supply 14 and the fluid transport channel of the tongue contacting instrument 12 as explained below.

In order to perform the non-mechanical mode of tongue deodorization, the ends of conduit 60 are respectively connected to the proximal end 38 of handle 18 and to the connector element 82 of container 58 to place the fluid inlet 43 in fluid communication with the container 58, which is supplied with the designated quantity of water 102. Plain ordinary water is supplied to the container 58 from an available water source, such as a tap or faucet, via the supply orifice 64. At this point in the procedure, the clamp 90 will be in the closed position so that the water does not yet flow into the fluid inlet 43 and fluid transport channel 42 of the tongue contacting instrument 12. The user manually grasps the handle 18 and manipulates the tongue contacting instrument 12 via the handle 18 to place the tongue rubbing surface 28 in contact with the tongue, and especially the dorsum of the tongue. The user manipulates the handle 18 to press the tongue rubbing surface 28 against the tongue and releases the clamp 90 for movement to the open position so that the water 102 flows by gravity from the container 58 and is discharged from the fluid outlet 44 of the tongue contacting instrument 12. While the water 102 is being discharged from the fluid outlet 44, the user manipulates the handle 18 to move the tongue rubbing surface 28 along the surface of the tongue. The tongue rubbing surface 28 is rubbed along as much as possible of the dorsum of the tongue, within comfort limits of the user. The tongue rubbing surface 28 can be rubbed against the surface of the tongue using back and forth rubbing strokes in any direction on the tongue. The water 102 is discharged from the fluid outlet 44 onto the tongue rubbing surface 28, as well as onto the tongue surface being contacted therewith. The water flows longitudinally and laterally over the tongue rubbing surface 28 as well as between the tongue rubbing surface and the surface of the tongue. The stainless steel tongue rubbing surface 28 in contact with the tissue of the tongue is reactive with the water 102 to bring about a non-mechanical reaction that reduces odor arising from the tongue. The quantity and flow rate of water 102 from the fluid outlet 44 ensures that a sufficient amount of water is present in the region where the tongue rubbing surface 28 contacts the surface of the tongue to effectively bring about the deodorizing reaction. The tongue rubbing surface 28 is rubbed against the tongue until the entire quantity of water in container 58 has been discharged from the fluid outlet 44. The first and second modes of tongue deodorization can be performed separately or in combination at desired intervals to deodorize the tongue.

Inasmuch as the present invention is subject to many variations, modifications and changes in detail, it is intended that all subject matter discussed above or shown in the accompanying drawings be interpreted as illustrative only and not be taken in a limiting sense.
