Description

la présente invention concerne une brosse à dents destinée notamment mais non esxclusivement à l'usage vétérinaire, pour le nettoyage dentaire de canidés et/ou de félidés.the present invention relates to a toothbrush intended in particular but not exclusively for veterinary use, for the dental cleaning of canines and / or felines.

Les problèmes parodontaux, tels que la parodontopathie, sont très fréquemment rencontrés chez les chiens et les chats ; cette maladie atteint plus électivement les dents du groupe incisif, qu'il est fréquent de devoir extraire en l'absence de prophylaxie.Periodontal problems, such as periodontal disease, are very commonly encountered in dogs and cats; this disease affects the teeth of the incisor group more electively, which it is common to have to extract in the absence of prophylaxis.

Tout comme chez l'homme, le seul moyen pour protéger les dents de ces animaux consiste en un brossage régulier, de préférence avec une pâte dentifrice adaptée, pour éliminer la plaque dentaire se développant sur la dent et dans le sulcus gingival et empêcher par le fait la constitution de tartre.As in humans, the only way to protect the teeth of these animals is by regular brushing, preferably with a suitable toothpaste, to remove the dental plaque developing on the tooth and in the gingival sulcus and prevent by the builds up tartar.

Les brosses à dents classiques, constituées d'un manche rectiligne dont l'une des extrémités, munie de poils, constitue la tête de travail, ne sont pas pratiques à utiliser pour un opérateur qui généralement effectue le nettoyage face à l'animal. Etant donné la forme particulière de la mâchoire des animaux, ces brosses nécessitent en effet des déplacements angulaires importants pour traiter toute la surface dentaire ; ces mouvements ne permettent pas une efficacité optimale du brossage et ne facilitent pas le travail du technicien qui doit en même temps maintenir fermement l'animal souvent agité en permanence.Conventional toothbrushes, consisting of a straight handle, one end of which, provided with bristles, constitutes the working head, are not practical to use for an operator who generally performs cleaning in front of the animal. Given the particular shape of the jaws of animals, these brushes indeed require significant angular displacements to treat the entire dental surface; these movements do not allow optimal brushing efficiency and do not facilitate the work of the technician who must at the same time firmly maintain the animal, often agitated constantly.

la présente invention a pour but de proposer un outil adapté à l'usage vétérinaire, permettant un brossage facile et efficace des dents de tous types d'animaux.The present invention aims to provide a tool suitable for veterinary use, allowing easy and effective brushing of the teeth of all types of animals.

la brosse à dents selon l'invention est constituée d'une tête de travail en forme de brosse munie de poils, solidaire d'un manche de préhension. La tête est décalée vers l'extérieur, du côté du dos du manche et disposée en retrait par rapport à l'axe dudit manche, la partie active des poils étant orientée vers ledit axe . La tête de travail est avantageusement raccordée au manche par un prolongement intermédiaire ; selon un mode de réalisation préféré, la brosse à dents comporte une tête orientée d'un angle de l'ordre de 30 à 50° environ par rapport à l'axe du manche ; cet angle est de préférence de 45° environ.the toothbrush according to the invention consists of a brush-shaped working head provided with bristles, integral with a grip handle. The head is offset towards the outside, on the side of the back of the handle and disposed in withdrawal with respect to the axis of said handle, the active part of the bristles being oriented towards said axis. The working head is advantageously connected to the handle by an intermediate extension; according to a preferred embodiment, the toothbrush has a head oriented at an angle of about 30 to 50 ° about the axis of the handle; this angle is preferably about 45 °.

Ces caractéristiques particulières permettent à un opérateur positionné face à l'animal, ou sur le côté, d'être très à l'aise pour brosser efficacement les dents de ce dernier.These particular characteristics allow an operator positioned in front of the animal, or on the side, to be very comfortable in effectively brushing the latter's teeth.

Etant donné l'application particulière de cette brosse et notamment en liaison avec l'agitation permanente de l'animal, il est nécessaire à l'opéarateur d'avoir une prise en main solide du manche pour réaliser des gestes précis. A cet effet, la brosse à dents comporte un manche "outil", constitué d'un corps sensiblement cylindrique, bombé sur le dos. Ce manche est conformé pour être facilement préhensible en pleine main ; sa longueur est adaptée pour un positionnement correct dans la main de l'utilisateur et à cet effet, son extrémité est destinée à venir reposer dans le fond de la paume, au niveau de l'éminence hypothénar.Given the particular application of this brush and in particular in connection with the permanent agitation of the animal, it is necessary for the operator to have a solid grip of the handle to perform precise gestures. To this end, the toothbrush has a "tool" handle, consisting of a substantially cylindrical body, curved on the back. This handle is shaped to be easily gripped in the hand; its length is adapted for correct positioning in the hand of the user and for this purpose, its end is intended to come to rest in the bottom of the palm, at the level of the hypothenar eminence.

Selon une disposition complémentaire, le dos du manche est muni, au moins sur sa partie avant, d'un bossage longitudinal, en saillie, formant guide de rotation. Ce bossage constitue un appui permettant d'imprimer un mouvement de roulis du manche, au moyen du pouce ou de l'index par exemple, pour faire pivoter facilement la brosse dans un sens ou dans l'autre. L'association manche-outil et guide de rotation assure tout type de prise en main, quelle que soit la taille de cette main.According to an additional arrangement, the back of the handle is provided, at least on its front part, with a protruding longitudinal boss, forming a rotation guide. This boss constitutes a support making it possible to impart a rolling movement of the handle, by means of the thumb or the index finger for example, to easily rotate the brush in one direction or the other. The handle-tool and rotation guide association ensures any type of grip, regardless of the size of this hand.

Toujours selon l'invention, la brosse à dents comporte un ergot de protection et de blocage, disposé dans le prolongement du dos de son manche, au niveau du raccordement du prolongement de la tête. Cet ergot permet un appui du pouce ou de l'index de l'utilisateur, assurant ssurant ainsi stabilité, guidage et précision ; il permet également une protection de ce pouce et de la main pour éviter leur butée contre les dents de l'animal ou une morsure accidentelle.Still according to the invention, the toothbrush comprises a protection and locking lug, arranged in the extension of the back of its handle, at the connection of the extension of the head. This lug allows support of the user's thumb or forefinger, thus ensuring stability, guidance and precision; it also allows protection of this thumb and hand to avoid their abutment against the teeth of the animal or an accidental bite.

Les brosses à dents classiques ne sont pas non plus adaptées à un brossage convenable en application vétérinaire. Cette inadaptation est liée à la forme particulière de la mâchoire des animaux et, également, à leur grande sensibilité gingivale. L'invention a également pour but de pallier à cet inconvénient et, selon une disposition complémentaire, la tête de brossage est constituée d'un support dans lequel sont implantées des touffes de poils, lesdits poils ayant des longueurs déterminées de façon à définir une surface de brossage convexe. Les poils centraux de la brosse ont ainsi une longueur plus importante que les poils d'extrémité. les poils utilisés sont choisis parmi les plus souples.Conventional toothbrushes are also not suitable for proper brushing in application veterinary. This maladjustment is linked to the particular shape of the jawbone of the animals and, also, to their great gingival sensitivity. The invention also aims to overcome this drawback and, according to an additional arrangement, the brushing head consists of a support in which tufts of bristles are implanted, said bristles having lengths determined so as to define a surface convex brushing. The central bristles of the brush thus have a greater length than the end bristles. the bristles used are chosen from the most flexible.

Mais l'invention sera encore illustrée, sans être aucunement limitée, par la description suivante d'un mode de réalisation particulier, donné à titre d'exemple et représenté sur les dessins annexés dans lesquels :

  • la figure 1 est une vue de côté de la brosse à dents selon l'invention ;
  • la figure 2 est une section, selon 2-2 de la figure 1 ;
  • la figure 3 est une vue partielle montrant leraccordement de la tête de travail à la partie intermédiaire.
   tel qu'on l'a représent, sur les figures, la brosse à dents est constituée d'une tête de travail 1 solidarisée au manche de préhension 2 par une partie intermédiaire 3.However, the invention will be further illustrated, without being in any way limited, by the following description of a particular embodiment, given by way of example and shown in the appended drawings in which:
  • Figure 1 is a side view of the toothbrush according to the invention;
  • Figure 2 is a section along 2-2 of Figure 1;
  • Figure 3 is a partial view showing the connection of the working head to the intermediate part.
as shown, in the figures, the toothbrush consists of a working head 1 secured to the grip handle 2 by an intermediate part 3.

La tête de brossage 1 est constituée d'un plateau support 4 dans lequel sont implantés les poils 5, par touffes, qui forment la brosse proprement dite. La partie intermédiaire 3 est en forme de prolongement du support 4 et elle vient se raccorder à l'extrémité du manche 2, de façon décalée par rapport à l'axe longitudinal 6 de ce dernier.The brushing head 1 consists of a support plate 4 in which the bristles 5 are located, in tufts, which form the brush itself. The intermediate part 3 is in the form of an extension of the support 4 and it is connected to the end of the handle 2, offset from the longitudinal axis 6 of the latter.

Ce décalage, selon un angle a de l'ordre de 30 à 50°, et de préférence voisin de 45°, est réalisé vers l'extérieur, du côté du dos 7 du manche 2. La tête de brossage 1 se situe en retrait par rapport à l'axe longitudinal 6 du manche 2 et la partie active des poils 5 implantés dans le support 4 est orientée vers cet axe 6.This offset, at an angle a of the order of 30 to 50 °, and preferably close to 45 °, is made outwards, on the back side 7 of the handle 2. The brushing head 1 is set back relative to the longitudinal axis 6 of the handle 2 and the active part of the bristles 5 implanted in the support 4 is oriented towards this axis 6.

La tete 1 est éloignée de l'extrémité du manche 2 et du coude de l'outil grâce à la partie intermédiaire inclinée 3. La longueur de cette partie intermédiaire 3 est adaptée à tout type d'animal ; cette longueur, de l'ordre de 7 à 10 cm, correspond de préférence à la profondeur de mâchoire la plus importante chez le chien de grande taille, à partir de la commissure des lèvres.The head 1 is distant from the end of the handle 2 and from the elbow of the tool thanks to the inclined intermediate part 3. The length of this intermediate part 3 is suitable for any type of animal; this length, of the order of 7 to 10 cm, preferably corresponds to the greatest jaw depth in large dogs, from the corner of the lips.

les différentes parties : tête 1, manche 2 et partie intermédiaire 3, se situent dans le même plan orienté parallèlement à l'axe des poils 5.the different parts: head 1, handle 2 and intermediate part 3, are located in the same plane oriented parallel to the axis of the bristles 5.

Afin de permettre une bonne prise en main de la brosse, le manche 2 est en forme de manche "outil". Il consiste en un corps sensiblement cylindrique et légèrement bombé au niveau de la partie arrière du dos 7. Le manche 2 présente un diamètre légèrement croissant de l'avant vers l'arrière ; le diamètre moyen est de l'ordre de 2 à 2,5 cm. la longueur b du manche est de l'ordre de 10 à 13 cm ; elle est adaptée pour un positionnement correct et une bonne tenue dans la main de l'opérateur quelle que soit sa taille. Cette longueur doit en effet permettre à l'extrémité du manche de venir reposer dans le fond de la paume de l'opérateur, contre son éminence hypothénar.In order to allow a good grip of the brush, the handle 2 is in the form of a "tool" handle. It consists of a substantially cylindrical and slightly domed body at the rear part of the back 7. The handle 2 has a slightly increasing diameter from the front to the rear; the average diameter is of the order of 2 to 2.5 cm. the length b of the handle is of the order of 10 to 13 cm; it is suitable for correct positioning and good grip in the operator's hand, whatever its size. This length must indeed allow the end of the handle to come to rest in the bottom of the operator's palm, against its hypothenar eminence.

Cette longueur, adaptée à la forme particulière du manche, permet un excellent blocage de l'outil, nécessaire à son utilisation pour le traitement d'animaux parfois récalcitrants.This length, adapted to the particular shape of the handle, allows excellent locking of the tool, necessary for its use for the treatment of sometimes recalcitrant animals.

Comme on le remarque figure 2, la base du manche 2 comporte un méplat 2a qui détermine une surface de pose pour l'outil, avec la tête 1 surélevée. Cette caractéristique présente des avantages au niveau pratique et également au niveau de l'hygiène en évitant le contact des poils 5 avec la surface support : on l'obtient grâce à la position en retrait de la tête 1 par rapport à l'axe 6 du manche 2.As can be seen in Figure 2, the base of the handle 2 comprises a flat part 2a which defines a bearing surface for the tool, with the elevated head 1. This characteristic has advantages at a practical level and also at a hygienic level by avoiding contact of the bristles 5 with the support surface: this is obtained by the recessed position of the head 1 relative to the axis 6 of the round 2.

Toujours en liaison avec son utilisation particulière, la zone coudée de raccordement entre le prolongement 3 de la tête 1 et le manche 2 comporte un ergot de protection et de blocage 8, en saillie. Cet ergot 8 est disposé sur la courbure de l'outil, dans le prolongement du dos 7 du manche 2 ; sa zone avant 8a permet la création d'un obstacle pour éviter les contacts des doigts ou de la main du technicien avec les dents de l'animal. Sa zone arrière 8b peut être adaptée, légèrement en creux pour le calage du pouce ou de l'index du manipulateur en fonction des régions dentaires à nettoyer. Cette caractéristique permet d'améliorer le blocage, le guidage, la stabilité et la précision de l'outil. La zone de calage 8b peut avantageusement être munie de rainures antidérapantes 8c, en saillie. Le positionnement de cet ergot 8, dans l'angle aigu formé par le manche et le prolongement 3 du support 4, permet d'obtenir une protection efficace au cours du brossage, lors du va et vient de l'outil, ou contre certaines agressivités de l'animal.Still in connection with its particular use, the angled connection zone between the extension 3 of the head 1 and the handle 2 comprises a protruding and locking lug 8, projecting. This lug 8 is disposed on the curvature of the tool, in the extension of the back 7 of the handle 2; its front zone 8 a allows the creation of an obstacle to avoid contact of the technician's fingers or hand with the teeth of the animal. Its rear zone 8b can be adapted, slightly recessed for the setting of the thumb or the index finger of the manipulator according to the dental regions to be cleaned. This characteristic makes it possible to improve the blocking, the guiding, the stability and the precision of the tool. The landing zone 8b can advantageously be provided with non-slip grooves 8c projecting. The positioning of this lug 8, in the acute angle formed by the handle and the extension 3 of the support 4, makes it possible to obtain effective protection during brushing, during the coming and going of the tool, or against certain aggressiveness of the animal.

Afin de parfaire l'efficacité de la brosse à dents, on a prévu sur la partie avant du dos 7 du manche 2, un bossage longitudinal, en saillie, visible en section figure 2. Cet bossage, en forme de guide de rotation 9, s'étend de la base de l'ergot 8 jusqu'à sensiblement la partie centrale du manche 2 ; il constitue un appui pour le pouce ou les doigts du manipulateur permettant d'imprimer un mouvement de roulis du manche 2 dans la main, lequel mouvement de roulis est utile notamment pour changer le côté de brossage. Le guide 9 permet également de soutenir le doigts en position arrêtée, au choix de l'utilisateur et quel que soit l'angle de rotation choisi.In order to perfect the effectiveness of the toothbrush, there is provided on the front part of the back 7 of the handle 2, a protruding longitudinal boss, visible in section FIG. 2. This boss, in the form of a rotation guide 9, extends from the base of the lug 8 to substantially the central part of the handle 2; it constitutes a support for the thumb or the fingers of the manipulator making it possible to impart a roll movement of the handle 2 in the hand, which roll movement is useful in particular for changing the brushing side. The guide 9 also makes it possible to support the fingers in the stopped position, at the choice of the user and whatever the angle of rotation chosen.

La qualité de brossage de la mâchoire de l'animal est améliorée par une conformation particulière de la surface de brossage réalisée par l'association des poils 5. Les poils 5 sont implantés par touffes dans le plateau support 4, de façon classique. Le nombre de touffes et le nombre de poils, associés à leur resserrement, sont adaptés selon la surface de brossage désirée. Cette surface de brossage peut varier de l'ordre de 1 à 3 cm² suivant l'animal à traiter. On peut aussi prévoir unr brosse comportant 24 à 42 touffes de poils s'étendant sur trois ou quatre rangées parallèles.The brushing quality of the animal's jaw is improved by a particular conformation of the brushing surface produced by the association of the bristles 5. The bristles 5 are implanted in tufts in the support plate 4, in a conventional manner. The number of tufts and the number of bristles, associated with their tightening, are adapted according to the desired brushing surface. This brushing surface can vary on the order of 1 to 3 cm² depending on the animal to be treated. It is also possible to provide a brush comprising 24 to 42 tufts of bristles extending over three or four parallel rows.

La mâchoire des canidés en particulier n'est pas rectiligne ; elle présente, latéralement, une courbure concave. On a adapté la tête de la brosse à cette configuration particulière en prévoyant des poils d'extrémité 5a plus courts que les poils centraux 5b. Les poils d'extrémité 5a peuvent avoir une longueur de l'ordre de 0,6 cm et les poils centraux une longueur de l'ordre de 1 cm ; les poils intermédiaires ont une longueur comprise entre ces deux valeurs de façon à conférer à la brosse une surface de brossage convexe, visible figure 1.The jaws of canines in particular are not straight; it has, laterally, a concave curvature. We adapted the brush head in this particular configuration by providing end bristles 5 is shorter than the hairs central 5b. The end bristles 5 a can have a length of the order of 0.6 cm and the central bristles a length of the order of 1 cm; the intermediate bristles have a length between these two values so as to give the brush a convex brushing surface, visible in FIG. 1.

La surface de brossage correspond à un arc de cercle dont le rayon est de l'ordre de 2,43 cm. Cette forme particulière de la brosse proprement dite permet à la tangente de l'arc de cercle de s'insinuer dans les creux et améliore la qualité du nettoyage.Les gestes nécessitent moins de précision de la part du technicien et cette forme permet également de faciliter la préhension de dentifrice d'un pot de conditionnement.The brushing surface corresponds to an arc of a circle whose radius is around 2.43 cm. This particular shape of the brush itself allows the tangent of the arc to creep into the hollows and improves the quality of cleaning. The gestures require less precision on the part of the technician and this shape also makes it possible to facilitate gripping toothpaste from a packaging jar.

Etant donné la grande sensibilité gingivale des animaux, on utilisera de préférence des poils 5 très souples soit par exemple obtenus au moyen de fibres souples polyamide 6-12 de 17/100ème de diamètre, soit à partir de fibres extra-souples polyamide 6-12 de 15/100ème de diamètre, soit une combinaison des deux.Given the great gingival sensitivity of the animals, preferably very soft bristles 5 will be used, for example obtained by means of flexible polyamide 6-12 fibers 17 / 100th in diameter, or from extra-flexible polyamide 6-12 fibers. 15 / 100th in diameter, a combination of both.

On peut par exemple prévoir une tête de grande dimension, pour les grands animaux, avec une oo plusieurs rangées de poils internes, ayant une souplesse moyenne (souple polyamide 6-12 de 17/100ème), encadrées par une ou plusieurs rangéers de poids latéraux extra-souples (polyamide 6-12 de 15/100ème ) et une tête de petite dimension, pour les petits animaux, avec uniquement des poils extra-souples polyamide 6-12 de 15/100ème.One can for example provide a large head, for large animals, with oo several rows of internal hairs, having a medium flexibility (flexible polyamide 6-12 of 17 / 100th), framed by one or more storiers of lateral weights extra-flexible (polyamide 6-12 15 / 100th) and a small head, for small animals, with only extra-flexible polyamide 6-12 hair 15 / 100th.

On a représenté, sur la figure 3, le plateau 4 de la tête de travail 1, vu de dos, et raccordé à la partie intermédiaire 3 qui s'étend dans le même plan. La partie intermédiaire 3 se rétrécie du manche 2 vers le plateau 4 pour former un coin qui se raccorde audit plateau en formant deux étranglements latéraux 10. Une fois la tête 1 introduite dans la gueule de l'alimal, cette caractéristique facilie le brossage de la face médiale de la denture dans le cas où l'animal ferme la mâchoire. La forme particulière de la partie intermédiaire 3 permet de forcer l'introduction de la brosse pour réaliser les mouvements de va et vient nécessaires.There is shown in Figure 3, the plate 4 of the working head 1, seen from the back, and connected to the intermediate part 3 which extends in the same plane. The intermediate part 3 narrows from the handle 2 towards the plate 4 to form a corner which connects to said plate by forming two lateral throttles 10. Once the head 1 introduced into the mouth of the animal, this characteristic facilitates brushing of the medial face of the teeth in the case where the animal closes the jaw. The particular shape of the intermediate part 3 makes it possible to force the introduction of the brush to make the necessary back and forth movements.

Le plateau support 4 comporte de préférence des bords arrondis pour le rendre aussi atraumatique que possible en cas de contact avec la gencive de l'animal.The support plate 4 preferably has rounded edges to make it as atraumatic as possible in the event of contact with the gum of the animal.

La brosse à dents selon l'invention est obtenu e monobloc, à l'exception des poils 5, par moulage d'un matériau plastique tel que du polyprolylène.The toothbrush according to the invention is obtained in one piece, with the exception of the bristles 5, by molding a plastic material such as polyprolylene.

Dans d'autres variantes, il sera possible de prévoir une brosse à dents à tête interchangeable de façon à permettre une adaptation rapide de l'outil en fonction de l'animal, ou pour changer aisément cett tête en cas d'usure.In other variants, it will be possible to provide a toothbrush with interchangeable head so as to allow rapid adaptation of the tool according to the animal, or to easily change this head in the event of wear.

Les signes de référence insérés après les caractéristiqes techniques mentionnées dans les revendications ont pour seul but de faciliter la compréhension de ces dernières et n'en limitent aucunement la portée.The reference signs inserted after the technical characteristics mentioned in the claims have the sole purpose of facilitating the understanding of the latter and in no way limit their scope.
