Description
- This patent application claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Patent Application No. 61/380,425, filed Sep. 7, 2010, which application is incorporated herein by reference.
- The invention broadly relates to veterinary tooth brushes, more specifically to a veterinary tooth brush having a plurality of brush heads, and even more particularly to a veterinary tooth brush with two or more brush heads arranged in series to simultaneously clean a quadrant of a set of teeth of an animal.
- Regular brushing of the teeth is important in maintaining the oral and general health of humans and animals alike. Plaque accumulates on the surfaces of dogs' and cats' teeth in the same manner as in humans. Some distinct differences do occur though. For instance, the tongue side of a dog's teeth is self-cleansing. Actions such as chewing and panting remove plaque on the inner surfaces of the teeth. Consequently, these surfaces do not need to be cleaned routinely by the owner. Also, often only the cheek side surfaces are available to be cleaned as the tongue sides are difficult to access. Further, plaque accumulates at different rates and concentrations in different areas of the mouth. The maxillary teeth in the back of the mouth near the cheek side salivary glands accumulate plaque the fastest and the canine teeth, also known as the fangs, accumulate minimal plaque. The upper back molars are the most important teeth for breaking down food, whereas the canine teeth are used only for tearing. In addition, the maxillary teeth for a dog and cat are not arranged in a general arch form as in humans. The back most teeth are inset with respect to the teeth in front of them creating an S-shaped arrangement of the maxillary teeth. Finally, there is tremendous variation in the size of canine jaws. The size differences can be divided into three groups, i.e., small, medium and large. The importance of daily home oral care for animals has been well documented. There has been a long-felt need for an animal tooth brush that is effective in reaching the plaque prone teeth and is user-friendly for the pet owner.
- Many devices have been created in an attempt to facilitate effective and proper cleaning of teeth, for example, U.S. Pat. Nos. 4,031,587; 4,738,001; 5,570,487; 5,791,007; 6,807,703; and, 7,383,603. Each of the devices disclosed in these patents suffers from defects and/or shortcomings that render them ineffective, such as complexity of design, improper angulation, insufficient force protection, etc. Thus, each device fails to meet the needs and constraints described above.
- The present invention is a tooth brush which assists a person in brushing an animal's teeth. In an embodiment, the present invention broadly comprises a tooth cleaning apparatus adapted to clean a set of teeth of an animal. The apparatus includes a handle portion having a vibration inducer, a controller for the vibration inducer and a power source, wherein the handle is arranged to enclose the vibration inducer, the controller and the power source. The apparatus further includes a head portion having a brush segment including at least two brush heads, each of the at least two brush heads has a plurality of brushes adapted to simultaneously clean the set of teeth, e.g., a quadrant of teeth. A distal brush head of the at least two brush heads has a plurality of brushes forming a concave surface and a proximal brush head of the at least two brush heads has a plurality of brushes forming a convex surface. In some embodiments, the handle portion is angled with respect to the surface of the brushes such that as the at least two brush heads are applied to the set of teeth, the handle portion is angled away from a midline of the animal's mouth by an angle of approximately 30-45 degrees. This arrangement protects the user from getting bitten by the animal. In some embodiments, the handle portion has a general ergonomic shape to conform to the user's hand.
- In some embodiments, the head portion includes a neck portion and the at least two brush heads. The at least two brush heads include a proximal brush head, i.e., closest to handle portion, and a distal brush head, i.e., furthest from the handle portion. The head portion is detachable from the handle, for example, by a simple twisting motion. The head portion includes at least two discreet brush heads attached to each other. In some embodiments, the proximal brush head is curvilinear outward, i.e., convex, and the distal brush head is curvilinear inward, i.e., concave. In addition to the curvilinear orientation, the distal brush head is held at an angle with respect to the proximal brush head. This is to conform to the S-shaped arrangement of the animal's posterior teeth. The distal brush head may be attached to the proximal brush head through a variety of connection types, e.g., a flexible, semi-flexible or rigid connection. This connection keeps the distal brush head at an angle with respect to the proximal brush head, i.e., a rest state angle. In some embodiments, with pressure, the distal brush head can open to an angle wider than the rest state angle relative to the proximal brush head. In some embodiments, each brush head is made of a plastic material with ultra soft nylon bristles to accommodate the sensitive gingival tissues of the animal. The brush heads, individually and/or in combination, may be made in different sizes, e.g., small, medium, and large, to account for the different jaw sizes of different breeds.
- In an embodiment, the present invention broadly comprises a tooth cleaning apparatus adapted to clean a set of teeth of an animal. The apparatus includes a handle portion and a head portion. The head portion includes a brush segment having at least two brush heads. Each of the at least two brush heads includes a plurality of brushes adapted to simultaneously clean a quadrant of the set of teeth. A distal brush head of the at least two brush heads includes a concave plurality of brushes and a proximal brush head of the at least two brush heads includes a convex plurality of brushes.

The overall dimensions ofhandle portion 10 are arranged to comfortably fit within the hand of a user, e.g., 12 centimeters in length and 2 centimeters in diameter.Handle portion 10 may be made of conventional materials in tooth brush manufacturing, for example, plastics. -
Handle portion 10 is angled with respect to the at least two brush heads, e.g., brush heads 26 and 28, such that as brush heads 26 and 28 are applied toteeth 30, in particular, backmolars 31,handle portion 10 is angled away frommidline 32 of the animal's head by an angle α, wherein α may be between 30-45 degrees (SeeFIG. 7 ). This is so that the most distal brush head, i.e.,brush head 28, can more easily reach around to brush the back most teeth. Also, this arrangement provides protection against the animal biting the user's hand while cleaning its teeth. It should be appreciated that angles larger than 45 degrees may also be used, and such variations are within the scope of the claimed invention. -
Head portion 34 comprises at least two brush heads, e.g.,distal brush head 28 andproximal brush head 26.Distal brush head 28 has backingmember 36 which is curvilinear inwards such that brushes 38 made up ofbristles 39 form a concave shape. Backingmember 36 may be formed from any material known in the art, e.g., plastic, whilebristles 39 may be formed from nylon material. Moreover, in some embodiments, backingmember 36 may be linear, and such variations are within the scope of the claimed invention. In some embodiments,brush head 28 is narrow with respect toproximal brush head 26, being only wide enough for two columns ofbristle tufts 40. Moreover,distal brush head 28 is angled inward with respect toproximal brush head 26, i.e., angle β. Inward angle β may take a variety of values, e.g., approximately 120 degrees.Proximal brush head 26 comprises backingmember 42 that is curvilinear outward so that brushes 44 made up ofbristles 45 form a convex shape. Backingmember 42 may be formed from any material known in the art, e.g., plastic, whilebristles 45 may be formed from nylon material. Moreover, in some embodiments, backingmember 42 may be linear, and such variations are within the scope of the claimed invention.

Proximal and distal brush heads 26 and 28, respectively, are arranged in series forming a relaxed “S” or “Z” shape. This is designed to conform to the “S” shape of the animal's row of teeth. It should be appreciated that regardless of the shape of backingmembers proximal brush head 26 anddistal brush head 28 form curved surfaces, e.g., convex and concave, respectively. It should be further appreciated that the shapes of the proximal and distal brush heads may vary, e.g., both are convex, both are concave, or the proximal brush head is concave while the distal brush head is convex. - In some embodiments, a third intermediate brush head, e.g.,
brush head 48, is affixed between proximal and distal brush heads 26 and 28, respectively.

With mild pressure, e.g., 2-4 Newtons, the connectingmember 56 can extend thereby opening the angle to a larger angle. As the operator moves the brush along the teeth towards the front of the mouth,distal brush head 28 is allowed to flex and extend with respect toproximal brush head 26 thereby riding along the contours of the teeth. Depending on the force desired to alter the angle between the proximal and distal brush heads, a flexible or semi-flexible material may be used, i.e., the less force desired the more flexible the material. - In some embodiments,
distal brush head 28 is solidly affixed toproximal brush head 26 and substantially no flexion/extension is possible. The fixed angle may be obtuse, e.g., 120 degrees. - In some embodiments, the bristles of both proximal and distal brush heads 26 and 28, respectively, are made of nylon. The diameter may be 0.003-0.006 inches. Thus, such bristles will be in the “soft” range. The bristles are on average approximately 10 millimeters in length; however, the bristle lengths may vary depending on the desired surface curvature of the brush head.
- In some embodiments, the distal and proximal brush heads comprise different numbers of brushes. For example, as shown in
FIG. 8 ,proximal brush head 58 comprises rows ofbrushes 60 where each row ofbrushes 60 comprises fourbrushes 62, whiledistal brush head 64 comprises rows ofbrushes 60 where each row ofbrushes 60 comprises a varying number ofbrushes 62 along the length ofdistal brush head 64. In other words, atfirst end 66 ofdistal brush head 64 there are threebrushes 62 in each row of brushes, while atsecond end 68 ofdistal brush head 64 there is onebrush 62 in the last row of brushes. Some of the rows of brushes betweenfirst end 66 andsecond end 68 ofdistal brush head 64 comprise two brushes 62. It should be appreciated that other configurations of brushes are also possible, e.g., an alternating pattern of twobrushes 62 and threebrushes 62, and such variations are within the scope of the claims. Furthermore, it should be appreciated that eachbrush - In some embodiments, the present invention tooth brush is manual, i.e., having no motor, switch or battery. The head portion is substantially the same as the above described embodiments, e.g., with or without the flexible material between the plurality of brush heads. An embodiment of such a tooth brush is shown in
FIG. 9 .Tooth brush 100 compriseshandle portion 102 andhead portion 104.Handle portion 102 may take a variety of forms, e.g., linear, ergonomic, enlarged, etc., and such variations are within the scope of the claims.Head portion 104 may be integral withhandle portion 102, or alternatively, may be releasably secured to handleportion 102, as described above.Head portion 104 comprisesdistal brush head 106 andproximal brush head 108. As shown inFIG. 9 ,distal brush head 106 andproximal brush head 108 may comprise substantiallylinear backing members brushes 114 is formed by varying the lengths ofbrushes 114 such that the brushes collectively they form an S-shape. - Thus, it is seen that the objects of the present invention are efficiently obtained, although modifications and changes to the invention should be readily apparent to those having ordinary skill in the art, which modifications are intended to be within the spirit and scope of the invention as claimed. It also is understood that the foregoing description is illustrative of the present invention and should not be considered as limiting. Therefore, other embodiments of the present invention are possible without departing from the spirit and scope of the present invention.
