Description

Brosse à dents à usage vétérinaireToothbrush for veterinary use
La présente invention concerne une brosse à dents destinée notamment, mais non exclusivement à l'usage vétérinaire pour le nettoyage dentaire des canidés et/ou des félidés.The present invention relates to a toothbrush intended in particular, but not exclusively for veterinary use for the dental cleaning of canids and / or felines.
Cette brosse à dents n'existe pas. Les vétérinaires spécialisés en dentisterie affirment que le seul moyen de protéger les dents des petits animaux est de brosser régulièrement les dents. Il faut savoir que la maladie parodontale ou parodontopathie est la maladie buccale la plus fréquemment rencontrée chez lescanidés et les félidés. Celle-ci atteint plus electivement les dents du groupe incisif qu'il est fréquent de devoir extraire en l'absence de prophylaxie.This toothbrush does not exist. Veterinarians specializing in dentistry claim that the only way to protect the teeth of small animals is to brush their teeth regularly. It should be known that periodontal disease or periodontopathy is the most frequently encountered oral disease in canines and felines. This more electively reaches the teeth of the incisor group which it is frequent to have to extract in the absence of prophylaxis.
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 ef¬ fectue le nettoyage face à l'animal. Etant donné la forme particulière de la mâchoire des animaux, ces brosses nécessitent en effet des dépla¬ cements 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. Le nettoyage devant être effectué face à l'animal.Conventional toothbrushes, consisting of a rectilinear handle, one end of which is 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 animal jaw, 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. Cleaning should be done in front of the animal.
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. lit à cet effet, la tête de la brosse forme un angle de 135° envi¬ ron avec le manche et présente un ou deux ergots placés d'un côté ou de part et d'autre du manche et situés 3 cm environ avant la courbure.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. bed for this purpose, the head of the brush forms an angle of 135 ° envi¬ ron with the handle and has one or two pins placed on one side or on either side of the handle and located about 3 cm before the curvature .
La première variante est une brosse à dents d'une seule pièce.The first variant is a one-piece toothbrush.
La deuxième variante est une brosse à dents a têtes interchangea¬ bles. La manche se termine alors par une partie mâle de section hexa¬ gonale évitant toute rotation de la partie interchangeable. La tête interchangeable comprend une partie femelle creuse de section hexa¬ gonale qui s'emboite par friction sur le manche. Cette friction s'exerce sur une longueur de 3 cm environ, ce qui permet une bonne stabilité de la tête dans son logement. Il faut exercer une pression pour obtenir l'emboîtement aximun. La désinsertion se faisant par simple traction simultanée des deux parties. Cette tête interchangeable est coudée formant un angle de 135°.The second variant is a toothbrush with interchangeable heads. The sleeve then ends with a male part of hexa¬ gonal section avoiding any rotation of the interchangeable part. The interchangeable head includes a hollow female part of hexa¬ gonal section which fits by friction on the handle. This friction is exerted over a length of approximately 3 cm, which allows good stability of the head in its housing. It is necessary to exert a pressure to obtain the nesting aximun. The disinsertion is done by simple simultaneous pull of the two parts. This interchangeable head is bent at an angle of 135 °.
FEUILLE DE REMPLACE ENT Le fait que cette brosse forme un angle de 135° avec le manche est l'une des originalités de cette invention qui permet d'être très à l'aise pour brosser les dents d'un chien car l'homme se trouve en face du chien. Une brosse à dents entièrement rectiligne ne serait pas du tout commode. De même, la grosseur et la longueur du manche favorisent une bonne tenue de la brosse dans la main. Les ergots des deux côtés du manche permettent le calage soit de l'index soit du pouce en fonctions des régions dentai¬ res à nettoyer.REPLACEMENT SHEET ENT The fact that this brush forms an angle of 135 ° with the handle is one of the original features of this invention which makes it very comfortable to brush the teeth of a dog because the man is in front of the dog. A fully straight toothbrush would not be at all convenient. Similarly, the size and length of the handle promote good grip of the brush in the hand. The lugs on both sides of the handle allow the setting either of the index finger or the thumb depending on the dental regions to be cleaned.
La troisième variante est une brosse à dents selon l'invention qui est constituée d'une tête de travail en forme de brosse, solidaire d'un manche de préhension et décalée vers l'extérieur, en retrait par rapport à l'axe dudit manche. La tête de travail est de préférence 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 40 à 50° enriron par rapport à l'axe du manche ; cet angle est de préférence de 45° environ.The third variant is a toothbrush according to the invention which consists of a brush-shaped working head, integral with a grip handle and offset towards the outside, set back with respect to the axis of said handle. . The working head is preferably connected to the handle by an intermediate extension. According to a preferred embodiment, the toothbrush has a head oriented at an angle of 40 to 50 ° around the axis of the handle; this angle is preferably about 45 °.
Ces caractéristiques particulières permettent à un opérateur posi¬ tionné face à l'animal, ou sur le côté, d'être très à l'aise pour bros¬ ser 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 a l'opérateur 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 formé pour être facilement préhensible en pleine main. Sa longueur est adaptée pour un bon positionnement dans la main de l'utili¬ sateur, son extrémité étant 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 formed to be easily gripped in the hand. Its length is suitable for good positioning in the hand of the user, its end being intended to come to rest in the bottom of the palm, at the level of the hypothenar eminence.
Selon une disposition complémentaire, cette brosse comporte un manche dont le dos est muni, au moins sur sa partie avant, d'un bossage longitu¬ dinal, en saillie formant guide de rotation. Ce bossage constitue un ap¬ pui permettant d'imprimer un mouvement du roulis du manche, au moyen du pouce ou de l'index par exemple, pour faire pivoter facilement la brosse dans un sens ou 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, this brush comprises a handle, the back of which is provided, at least on its front part, with a longitu¬ dinal boss, projecting forming a rotation guide. This boss constitutes an ap¬ permi to print a movement of the roll 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 association and rotation guide 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 man¬ che, au niveau du raccordement du prolongement de la tête.Still according to the invention, the toothbrush comprises a protection and blocking lug arranged in the extension of the back of its sleeve, at the connection of the extension of the head.
FEUILLE DE REMPLACEMENT 3 Cet ergot permet un appui du pouce ou de l'index de l'utilisateur, as¬ surant ainsi stabilité, guidage et précision ; il permet également une protection ._e ce pouce et de la main pour éviter leur butée contre les dents de l'animal ou une morsure accidentelle.REPLACEMENT SHEET 3 This lug allows support of the thumb or the index finger of the user, thus ensuring stability, guidance and precision; it also provides protection for your thumb and hand to prevent them from abutting the animal's teeth or 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 à pour but de pallier 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'extré¬ mité. Les poils utilisés sont choisis parmi les plus souples.Nor are conventional toothbrushes suitable for proper brushing in veterinary applications. This maladjustment is linked to the particular shape of the jaws of animals and, also, to their great gingival sensitivity. The object of the invention is to overcome this drawback and, according to a complementary 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 convex brushing surface. . The central bristles of the brush thus have a greater length than the bristles of extremity. The bristles used are chosen from among the most flexible.
De toute façon, l'invention sera mieux comprise à l'aide des dessins shëmatiques annexés représentant à titre d'exemples non limitatifs quelques formes de réalisation de cette brosse à dents pour félidés et/ ou canidés.In any case, the invention will be better understood with the aid of the appended schematic drawings showing, by way of nonlimiting examples, some embodiments of this toothbrush for felines and / or canines.

La figure 6 est une vue de profil de la brosse à dents selon l'in¬ vention.Figure 6 is a side view of the toothbrush according to the invention.
Lafigure 7 est une section selon 2-2 de la figure 6.Figure 7 is a section along 2-2 of Figure 6.
La figure 8 est une vue partielle montrant le raccordement de la tête de travail à la partie intermédiaire.Figure 8 is a partial view showing the connection of the working head to the intermediate part.
Tel qu'on l'a représenté sur les figures, la brosse à dents est constituée d'une tête de travail 1 solidarisée du manche de préhension 2 par une partie intermédiaire 3.As shown in the figures, the toothbrush consists of a working head 1 secured to the grip handle 2 by an intermediate part 3.
FEUILLE DE REMPLACEMENT La tête de brossage 1 est constituée d'un plateau de 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.REPLACEMENT SHEET The brushing head 1 consists of a support plate 4 in which the bristles 5 are located, in tufts, which form the actual brush. 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 40 à 50° et de préfé¬ rence voisin de 45°, est réalisé vers l'extérieur, du côté du dos 7 du manche 2. La tête de brossage 1 se situe donc en retrait par rapport à l'axe longitudinal 6 du manche 2 et la partie active des poils 5 implan¬ tés dans le support 4 est orientée vers cet axe 6.This offset, at an angle a. on the order of 40 to 50 ° and preferably around 45 °, is made outwards, on the back side 7 of the handle 2. The brushing head 1 is therefore 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 tête 1 est éloignée de l'extrémité du manche 2 et du coude de l'outil grâce à la partie intermédiaire incliné 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 longueur de la mâchoire la plus importante chez le chien de grande taille, à partir de la commissure des lèvres.The head 1 is moved away from the end of the handle 2 and from the elbow of the tool by virtue of the inclined intermediate part 3. The length of this intermediate part 3 is suitable for any type of animal * , this length of the around 7 to 10 cm, preferably corresponds to the longest jaw length in large dogs, starting from the corner of the lips.
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 cy¬ lindrique 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'ar¬ rière ; le diamètre moyen est de l'ordre de 2 à 2,5cm. La longueur b_ du manche est de l'ordre de 10 à 13 cm ; elle est adaptée pour un position¬ nement 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 ëminence 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 body which is substantially cylindrical and slightly rounded at the level of the rear part of the back 7. The handle 2 has a slightly increasing diameter from the front towards 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 holding in the operator's hand, whatever its size. This length must in fact 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 trai¬ tement 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 animals that are sometimes recalcitrant.
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 suréle¬ vée. 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.As can be seen in Figure 2, the base of the handle 2 has a flat 2a which determines a laying surface for the tool, with the head 1 suréle¬ vée. This characteristic has advantages at the practical level and also at the hygienic level by avoiding the contact of the bristles 5 with the support surface.
Toujours en liaison avec son utilisation particulière, la zone coudée de raccordement entre le prolongement 3 de la tête 1 et la manche 2 com¬ porte un ergot de protection et de blocage 8, en saillie.Still in connection with its particular use, the angled connection zone between the extension 3 of the head 1 and the sleeve 2 has a protective and locking lug 8, projecting.
FEUILLE DE REMPLACEMENT 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'amélio¬ rer le blocage, le guidage, la stabilité et la précision de l'outil. La zone de calage 8b_ peut avantageusement être munie de rainures antidéra¬ pantes 8£ , 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'ob¬ tenir une protection efficace au cours du brossage, lors du va et vient de l'outil, ou contre certaines agressivités de l'animal.REPLACEMENT SHEET This lug 8 is disposed on the curvature of the tool, in the extension of the back 7 of the handle 2; its front area 8a. allows the creation of an obstacle to avoid contact of the technician's fingers or hand with the animal's teeth. Its rear zone 8b can be adapted, slightly recessed, for setting 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 wedging zone 8b_ can advantageously be provided with anti-slip grooves 8 £, 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 7. Ce 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 mani¬ pulateur 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 doigt en position arrêtée, au choix de l'utilisateur et quel que soit l'angle de rotation choisi. 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 de support 4 de façon classique. Le nombre de touffes et le nom¬ bre 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 ainsi prévoir une brosse comportant 24 à 42 touffes de poils s'étendant sur trois ou quatre ran¬ gées parallèles.In order to perfect the effectiveness of the toothbrush, a longitudinal boss has been provided on the front part of the back 7 of the handle 2, visible in section Figure 7. This boss, in the form of a rotation guide 9 s' 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 finger in the stopped position, at the choice of the user and whatever the angle of rotation chosen. 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 cm 2 depending on the animal to be treated. It is thus 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'extré mité 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 1 cm ; les poils intermédiaires ont une longueur comprise en tre ces deux valeurs de façon à conférer à la brosse une surface de bros sage convexe, visible figure 6.The jaws of canines in particular are not straight; it presents, laterally, a concave curvature. The brush head has been adapted to this particular configuration by providing end bristles 5a_ which are shorter than the central bristles 5b. The end bristles 5a_ can have a length of the order of 0.6 cm and the central bristles a length of 1 cm; the intermediate bristles have a length comprised between these two values so as to give the brush a convex, smooth bros surface, visible in FIG. 6.
FEUILLE DE REMPLACEMENT 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 propre¬ ment dite permet à la tangente de l'arc de cercle de s'insinuer dans les creux et améliorer la qualité du nettoyage. Les gestes nécessitent moins de précision de la part du technicien et cette forme permet éga¬ lement de faciliter la préhension de dentifrice d'un pot de condition¬ nement.REPLACEMENT SHEET The brushing surface corresponds to an arc of a circle whose radius is around 2.43 cm. This particular shape of the clean brush allows the tangent of the arc to creep into the recesses and improve the quality of cleaning. The gestures require less precision on the part of the technician and this shape also makes it possible to facilitate the gripping of toothpaste from a packaging jar.
Etant donné la grande sensibilité gingivale des animaux, on utili¬ sera 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 et 15/100ème de diamètre, soit une combinaison des deux.Given the great gingival sensitivity of the animals, it will preferably be very soft bristles 5, for example obtained by means of flexible polyamide 6/12 fibers 17 / 100th in diameter, or from extra flexible polyamide fibers 6 / 12 and 15 / 100th in diameter, a combination of the two.
On peut par exemple prévoir une tête de grande dimension, pour les grands animaux, avec une ou plusieurs rangées de poils internes souples polyami e o/12 de 17/100ème encadrées par une ou plusieurs rangées de poils latéraux extra souples polyamide 6/12 de 15/100ème et unetête de petite dimension, pour les petits animaux, avec uniquement des poils extra-souples.One can for example provide a large head, for large animals, with one or more rows of flexible internal polyami eo / 12 of 17 / 100th hairs framed by one or more rows of extra flexible polyamide side hairs 6/12 of 15 / 100th and a small head, for small animals, with only extra-soft bristles.
On a représenté sur la figure 8, 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 pla¬ teau 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'animal, cette caractéristique facilite le brossage de la face média- le de ls denture dans le cas où l'animal ferme la mâchoire. La forme par¬ ticulière de la partie intermédiaire 3 permet de forcer l'introduction de la brosse poux réaliser les mouvements de va et vient nécessaire.There is shown in Figure 8, 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 wedge which connects to said plate by forming two lateral throttles 10. Once the head 1 inserted into the mouth of the animal, this characteristic facilitates brushing of the media side of the teeth if the animal closes the jaw. The particular shape of the intermediate part 3 makes it possible to force the introduction of the lice brush to carry out the movements back and forth necessary.
Le plateau support 4 comporte de préférence des bords arrondis pour le rendre aussi atraumatique que possible en cas de contact avec la m⬠choire 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 jaw of the animal.
La brosse à dents selon l'invention est obtenue monobloc, à l'excep¬ tion des poils 5, par moulage d'un matériau plastique tel que du polypro- pylène.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 polypropylene.
Les signes de référence insérés après les caractéristiques techni¬ ques 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.
