Abstract
Description
La présente invention concerne un dispositif à jet dentaire fonctionnant par I compression et dont les dimensions sont suffisamment miniaturisées pour remplacer un cure-dent et facilement jetable. I On connaît jusqu'à présent pour les soins dentaires des bains de bouche, 1 associés ou non à des cure-dents. 11 a été inventé et déposé à l'INPI le 08 mars 2006, un brevet sous le numéro 0602116 et dénommé: dispositif à jet dentaire individuel caractérisé par un réservoir de faible volume contenant un liquide aseptisant et formé par un bouchon doté d'un conduit terminé par un bec effilé. Ce dispositif a l'inconvénient de projeter le liquide aseptisant sous une faible pression entre la partie de la gencive séparant deux dents. The present invention relates to a dental jet device operating by compression and whose dimensions are sufficiently miniaturized to replace a toothpick and easily disposable. To date dental care has been known for mouthwashes, whether or not associated with toothpicks. It was invented and deposited at the INPI on March 08, 2006, a patent under the number 0602116 and called: an individual dental jet device characterized by a small volume reservoir containing a liquid sanitizer and formed by a plug with a conduit finished with a tapered beak. This device has the disadvantage of projecting the liquid sanitizer under a low pressure between the portion of the gingiva separating two teeth.
La présente invention permet de palier à cet inconvénient au dispositif destiné à projeter violemment sous forte pression un mini jet de liquide aseptisant destiné à 15 nettoyer efficacement les interstices séparant deux dents d'une mâchoire. The present invention overcomes this disadvantage to the device for projecting violently under high pressure a mini jet of liquid sanitizer for effectively cleaning the interstices separating two teeth of a jaw.
Le principe consiste à comprimer un mini réservoir plat en plastique séparé par une membrane (4) dont la partie inférieure contient le liquide aseptisant (12). Le réservoir est pourvu à l'intérieur d'un tube (10) terminé à son extrémité supérieure 20 par un conduit (3) guidant le jet. La partie inférieure du tube (20) traverse la membrane (4) et plonge dans le liquide aseptisant En outre, il est doté d'une vanne anti-retour (5) placée au niveau inférieur du tube et destinée à s'obstruer lorsque l'on comprime le réservoir entre le pouce et l'index sur sa partie supérieure. The principle is to compress a plastic mini tank separated by a membrane (4) whose lower part contains the liquid sanitizer (12). The tank is provided inside a tube (10) terminated at its upper end 20 by a conduit (3) guiding the jet. The lower part of the tube (20) passes through the membrane (4) and is immersed in the sanitizing liquid. In addition, it is provided with a non-return valve (5) placed at the lower level of the tube and intended to be clogged when the the reservoir is compressed between the thumb and forefinger on its upper part.
25 Ainsi conçu le dispositif permet de projeter un jet de liquide aseptisant dont la puissance est proportionnelle à la fois à la pression imposée sur le tube plastique souple et le diamètre émergeant du tube capillaire dirigé sur la dent. Le liquide aseptique épuisé est renouvelé en puisant dans le réservoir inférieur lorsque la pression sur le tube cesse. 30 Le fonctionnement ainsi défini, le dispositif, objet de la présente invention, est composé d'un microréservoir (1) réalisé en plastique souple, séparé intérieurement par une membrane (4). Ledit réservoir est coiffé par un bouchon (2) doté à son extrémité d'un effilé (7) constituant l'extrémité du capillaire traversant le bouchon (2) qui est prolongé dans le microréservoir par un tube (10) doté à sa partie inférieure d'une vanne anti-retour (5) surmontée au dessus d'un orifice (6) servant à puiser le liquide antiseptique lorsque le microréservoir reprend sa position de repos. Thus designed the device allows to project a jet of liquid sanitizer whose power is proportional to both the pressure imposed on the flexible plastic tube and the diameter emerging from the capillary tube directed on the tooth. The spent aseptic liquid is renewed by drawing from the lower reservoir when the pressure on the tube ceases. The operation thus defined, the device object of the present invention is composed of a microreservoir (1) made of flexible plastic, internally separated by a membrane (4). Said reservoir is capped by a plug (2) endowed at its end with a taper (7) constituting the end of the capillary passing through the plug (2) which is extended in the microreservoir by a tube (10) provided at its lower part a non-return valve (5) surmounted above an orifice (6) for drawing the antiseptic liquid when the microreservoir returns to its rest position.
L'invention ainsi résumée sera mieux comprise grâce aux dessins annexés qui 10 ne sont présentés qu'à titre d'exemple voulu par l'inventeur. The invention thus summarized will be better understood from the accompanying drawings which are presented only by way of example intended by the inventor.
La figure 1 de la planche 1/1 représente le dispositif vu en coupe. Figure 1 of the plate 1/1 shows the device seen in section.
La figure 2 e la planche 1/1 représente le dispositif de pulvérisation avec la 15 vanne anti-retour du dispositif. Figure 2 and Plate 1/1 shows the spraying device with the non-return valve of the device.
La figure 3 de la planche 1/1 représente l'extrémité utilisée pour pulvériser le liquide antiseptique ayant une forme fantaisie. Figure 3 of Plate 1/1 shows the end used to spray the antiseptic liquid having a fancy shape.
20 En se reportant à la figure 1 de la planche 1/1, on a dessiné le dispositif vu en coupe selon un profil vertical. Referring to Figure 1 of Plate 1/1, the device has been drawn in section in a vertical profile.
Le microréservoir (1) est réalisé en polyvinyle souple de quelque millimètres, de volume en deux chambres, l'une inférieure contenant le liquide antiseptique (12) 25 que l'on introduit au moyen d'un orifice obturable (11), l'autre supérieure (13) que l'on peut comprimer au moyen du pouce et de l'index d'une main. The microreservoir (1) is made of flexible polyvinyl of a few millimeters, of volume in two chambers, the lower one containing the antiseptic liquid (12) 25 which is introduced by means of a closable orifice (11), the another upper (13) which can be compressed by means of the thumb and forefinger of a hand.
Les deux chambres sont séparées au moyen d'une membrane (4) traversant le microréservoir (1). Ce dernier est coiffé au moyen d'un bouchon (2) percé par un 30 capillaire (7). The two chambers are separated by means of a membrane (4) passing through the microreservoir (1). The latter is capped by means of a stopper (2) pierced by a capillary (7).
La partie inférieure du conduit (10) plonge dans le liquide antiseptique contenu dans la chambre inférieure (12) qui retient ledit liquide au moyen d'une vanne anti-retour (5) localisée dans l'alvéole (8) moulée dans le tube (10). The lower part of the duct (10) is immersed in the antiseptic liquid contained in the lower chamber (12) which retains said liquid by means of a non-return valve (5) located in the cell (8) molded in the tube ( 10).
Le liquide contenu dans la partie supérieure du tube (10) est projeté au moyen d'une compression appliquée à la main à l'orifice (6) qui relie le tube (10) au capillaire effilé (7) du bouchon (2), ce dernier projetant le liquide antiseptique contenu au dessus dans la membrane (4) sous l'effet de la compression manuelle des doigts sur la chambre supérieure (3). The liquid contained in the upper part of the tube (10) is projected by means of compression applied by hand to the orifice (6) which connects the tube (10) to the tapered capillary (7) of the stopper (2), the latter projecting the antiseptic liquid contained above in the membrane (4) under the effect of the manual compression of the fingers on the upper chamber (3).
Après la compression, la dépression subie par la chambre (13) réaspire un volume de liquide antiseptisant contenu dans la chambre (12) au moyen de la w antiretour (5) qui s'ouvre par la dépression des deux chambres. After the compression, the depression undergone by the chamber (13) re-aspirates a volume of antiseptic liquid contained in the chamber (12) by means of the w antirétour (5) which opens by the depression of the two chambers.
Lorsque les pressions sont équivalentes entre les chambres (12) et (1 h vanne anti-retour se referme. When the pressures are equivalent between the chambers (12) and (1h non-return valve closes.
On nettoie ainsi successivement les interstices des gencives entre les dents. In this way, the interstices of the gums are cleaned successively between the teeth.
On a représenté sur la figure 2 de la planche 1/1, le fonctionnement de la vanne anti-retour (5). FIG. 2 of plate 1/1 shows the operation of the non-return valve (5).
La vanne anti-retour a été réalisée au moyen de matériaux plus dense que la densité du liquide antiseptique dentaire contenu dans la chambre (12). Ce liquide antiseptique a été introduit ans la chambre (12) au moyen d'un vide de celle-ci provoqué au moment de la fabrication du dispositif à jet dentaire au moyen de l'appendice (11) plastique soudée au moment de la finition.25 La vanne anti-retour (5) est contenue à l'intérieur du tube (10) au niveau où ce dernier traverse la membrane (4) et plonge au fond du niveau du réservoir (12) contenant le liquide antiseptique dentaire. The non-return valve was made of materials denser than the density of dental antiseptic fluid contained in the chamber (12). This antiseptic liquid was introduced into the chamber (12) by means of a vacuum thereof caused at the time of manufacture of the dental jet device by means of the welded plastic appendix (11) at the time of finishing. The check valve (5) is contained inside the tube (10) at the level where the latter passes through the membrane (4) and plunges at the bottom of the level of the reservoir (12) containing the dental antiseptic liquid.
Au repos, le liquide antiseptique dentaire contenu dans la chambre inférieure (12) déborde dans la chambre supérieure (f3) et lorsque le manipulateur exerce une pression sur la chambre (13), celle-ci réalisée en plastique souple se déforme, le liquide antiseptique pénètre dans l'orifice (6) du tube (10) placé au dessus de la membrane (4) et va se projeter avec violence au niveau du capillaire (7) terminant le conduit supérieur (3) solidaire du bec (2). At rest, the dental antiseptic liquid contained in the lower chamber (12) overflows into the upper chamber (f3) and when the manipulator exerts pressure on the chamber (13), the latter made of flexible plastic deforms, the antiseptic liquid penetrates into the orifice (6) of the tube (10) placed above the membrane (4) and will project violently at the level of the capillary (7) terminating the upper duct (3) integral with the spout (2).
Dans une version ergonomique, le bec (2) se termine au moyen d'une figure fantaisie représentant un bec de canard facilement dissociable du conduit supérieur (3) et prolongeant le capillaire (2). Il est possible de réaliser un dispositif fonctionnant selon un principe semblable en réalisant le conduit (10) dont le diamètre est très supérieur au conduit capillaire (7). In an ergonomic version, the spout (2) ends with a fancy figure representing a duckbill easily dissociable from the upper duct (3) and extending the capillary (2). It is possible to produce a device operating according to a similar principle by producing the conduit (10) whose diameter is much greater than the capillary duct (7).
