  • Orthopedic helmets are used to prevent and correct positional deformities of an infant's skull. Indeed, some infants may develop different pathologies resulting in cranial deformity, such as plagiocephaly, brachiocephaly, asymmetrical brachiocephaly or scaphorephaly. Positional plagiocephaly corresponds to an asymmetry of the cranial box of an infant. That is to say that the skull is not round but flattened, it is deformed.

In addition, when the clip is closed, it is locked to prevent the infant from opening the helmet with the hand, or by vigorously gesticulating the head, and losing the helmet. Locking the fastener consists in setting a constant distance between the two free ends. But poor adjustment can prevent normal growth of the convex parts of the skull.

Description

Casque orthopédique de correction d’une déformation positionnelle crânienne du nourrisson  Orthopedic helmet for correction of cranial positional deformation of infants
Domaine technique de l'invention Technical field of the invention
L’invention concerne les casques orthopédiques de correction d’une déformation positionnelle crânienne du nourrisson. État de la technique The invention relates to orthopedic helmets for correcting a cranial positional deformity of the infant. State of the art
Les casques orthopédiques sont utilisés pour empêcher et corriger des déformations positionnelles du crâne d’un nourrisson. En effet, certains nourrissons peuvent développer différentes pathologies entraînant une déformation crânienne, comme une plagiocéphalie, une brachiocéphalie, une brachiocéphalie asymétrique ou une scaphocéphalie. Une plagiocéphalie positionnelle correspond à une asymétrie de la boîte crânienne d’un nourrisson. C’est-à-dire que le crâne n’est pas rond mais aplati, il est déformé. Les casques orthopédiques visent à permettre au crâne de se former correctement avec le temps. Ces casques conviennent à des nourrissons âgés de trois à dix-huit mois. Orthopedic helmets are used to prevent and correct positional deformities of an infant's skull. Indeed, some infants may develop different pathologies resulting in cranial deformity, such as plagiocephaly, brachiocephaly, asymmetrical brachiocephaly or scaphorephaly. Positional plagiocephaly corresponds to an asymmetry of the cranial box of an infant. That is to say that the skull is not round but flattened, it is deformed. Orthopedic helmets aim to allow the skull to form properly over time. These helmets are suitable for infants aged three to eighteen months.
Un casque orthopédique est fait sur mesure. Il comporte une zone de remodelage délimitant un espace de poussée situé entre une partie aplatie du crâne et la zone de remodelage afin de permettre une croissance du crâne dans l’espace de poussée. Il comporte en outre des zones d’appui en contact avec les parties convexes du crâne de manière à obtenir un crâne rond. An orthopedic helmet is made to measure. It includes a remodeling area defining a thrust space between a flattened portion of the skull and the remodeling area to allow growth of the skull in the thrust space. It further comprises bearing areas in contact with the convex portions of the skull so as to obtain a round skull.
Par ailleurs, du fait de la croissance des os du crâne, il faut augmenter régulièrement la circonférence du casque. Pour cela, le casque est fendu sur une partie latérale, c’est-à-dire qu’il comporte deux extrémités libres, et une attache à fermeture réglable est montée sur les deux extrémités de manière à pouvoir ouvrir et fermer le casque et pour régler une distance séparant les deux extrémités. En réglant l’attache on peut augmenter la distance séparant les deux extrémités et augmenter la circonférence du casque afin de permettre au crâne de croître normalement. En outre, lorsque l’attache est fermée, elle est verrouillée pour empêcher le nourrisson d’ouvrir le casque avec la main, ou en gesticulant vigoureusement de la tête, et de perdre le casque. Le verrouillage de l’attache consiste à régler une distance constante entre les deux extrémités libres. Mais un mauvais réglage peut empêcher une croissance normale des parties convexes du crâne. Moreover, because of the growth of the bones of the skull, it is necessary to increase regularly the circumference of the helmet. For this, the helmet is split on a lateral part, that is to say that it has two free ends, and an adjustable closure fastener is mounted on both ends so as to be able to open and close the helmet and adjust a distance between the two ends. Adjusting the clip can increase the distance between the two ends and increase the circumference of the helmet to allow the skull to grow normally. In addition, when the clip is closed, it is locked to prevent the infant from opening the helmet with the hand, or by vigorously gesticulating the head, and losing the helmet. Locking the fastener consists in setting a constant distance between the two free ends. But poor adjustment can prevent normal growth of the convex parts of the skull.
Certaines attaches sont des bandes auto-agrippantes. Mais de telles bandes peuvent être facilement détachées par le nourrisson avec sa main. D’autres casques ont comme attache une bande munie d’un bouton poussoir, ou une lanière en plastique dentée coopérant avec un système anti-retour pour empêcher la lanière de quitter le système sans l’intervention d’un adulte. En particulier, les attaches à lanière dentée sont bruyantes et font penser à des os qui se cassent, ce qui peut effrayer certains parents lorsqu’ils règlent l’attache. En outre, ces attaches doivent également être réglées correctement et régulièrement pour s’adapter à la croissance osseuse du crâne, et tout mauvais réglage accidentel peut entraîner des traumatismes. Some fasteners are self-gripping tapes. But such strips can be easily detached by the infant with his hand. Other helmets are attached to a strip with a push button, or a toothed plastic strap cooperating with a non-return system to prevent the strap from leaving the system without the intervention of an adult. In particular, toothed strap fasteners are noisy and resemble bones that break, which can scare some parents when they adjust the clip. In addition, these fasteners must also be adjusted correctly and regularly to accommodate bone growth of the skull, and any accidental mis-adjustment may result in trauma.
Objet de l'invention Object of the invention
Un objet de l’invention consiste à pallier ces inconvénients, et plus particulièrement à fournir un casque orthopédique pour traiter les déformations positionnelles du nourrisson, qui permet une croissance du crâne tout en garantissant une bonne tenue du casque sur la tête du nourrisson. An object of the invention is to overcome these disadvantages, and more particularly to provide an orthopedic helmet for treating the positional deformations of the infant, which allows growth of the skull while ensuring a good resistance of the helmet on the infant's head.
Un autre objet est de fournir une attache réglable dont le réglage est silencieux. Another object is to provide an adjustable fastener whose adjustment is silent.
Selon un aspect de l’invention, il est proposé un casque orthopédique de correction d’une déformation positionnelle crânienne du nourrisson, comprenant une calotte ayant deux extrémités libres et une attache configurée pour relier les deux extrémités libres. According to one aspect of the invention, it is proposed an orthopedic helmet for correction of a cranial positional deformation of the infant, comprising a cap having two free ends and a fastener configured to connect the two free ends.
L’attache est élastique pour exercer une force de rappel sur les deux extrémités libres de manière à les rapprocher l’une vers l’autre, et pour permettre un éloignement des deux extrémités libres l’une de l’autre lorsque le crâne du nourrisson exerce une force de poussée supérieure à la force de rappel. The fastener is elastic to exert a restoring force on the two free ends so as to bring them towards each other, and to allow the two free ends to move away from each other when the skull of the infant exerts a pushing force greater than the restoring force.
On offre ainsi un casque dynamique adapté à la croissance du crâne sans nécessiter une intervention extérieure. L’attache élastique n’est pas verrouillée et permet une croissance du crâne. L’attache élastique est réglable automatiquement. Elle procure une force de serrage sur la calotte suffisante pour maintenir le casque sur le crâne du nourrisson, en empêchant le nourrisson de l’enlever du fait de ses mouvements de tête. La force de serrage est inférieure à la pression de poussée du crâne et empêche le crâne de subir un traumatisme du fait du casque. We offer a dynamic helmet adapted to the growth of the skull without requiring external intervention. The elastic fastener is not locked and allows growth of the skull. The elastic fastener is automatically adjustable. It provides a clamping force on the cap sufficient to hold the helmet on the skull of the infant, preventing the infant from removing it because of his head movements. The clamping force is less than the thrust pressure of the skull and prevents the skull from being traumatized by the helmet.
L’attache peut comporter un premier connecteur monté sur une première extrémité libre, un deuxième connecteur monté sur une deuxième extrémité libre, et un moyen élastique adapté pour être relié aux deux connecteurs. The clip may comprise a first connector mounted on a first free end, a second connector mounted on a second free end, and an elastic means adapted to be connected to the two connectors.
Le moyen élastique peut être relié de manière amovible à au moins un connecteur. The elastic means may be removably connected to at least one connector.
Le moyen élastique peut être relié de manière fixe à au moins un connecteur. The elastic means can be fixedly connected to at least one connector.
Le moyen élastique peut être un élastique ayant une forme filaire en boucle fermée. The elastic means may be an elastic having a closed loop wire form.
Le premier connecteur peut comporter une première butée conformée pour être reliée au moyen élastique et un guide allongé en saillie de la première extrémité libre, et le deuxième connecteur comporte une deuxième butée conformée pour être reliée au moyen élastique et au moins un ergot conformé pour coopérer avec le guide afin de permettre un déplacement des extrémités libres le long du guide. The first connector may comprise a first abutment shaped to be connected to the elastic means and an elongated guide projecting from the first free end, and the second connector comprises a second abutment shaped to to be connected to the elastic means and at least one shaped lug to cooperate with the guide to allow movement of the free ends along the guide.
Un orifice allongé peut être formé dans le guide et être conformé pour recevoir ledit au moins un ergot de sorte que ledit au moins un ergot coulisse au sein de l’orifice. An elongate hole may be formed in the guide and be shaped to receive said at least one lug so that said at least one lug slides within the hole.
Selon un mode de réalisation, le deuxième connecteur comporte deux ergots cylindriques pour empêcher une rotation du guide autour d’un ergot. According to one embodiment, the second connector has two cylindrical lugs to prevent rotation of the guide around a lug.
Selon un autre mode de réalisation, le deuxième connecteur comporte un ergot ayant une forme oblongue pour empêcher une rotation du guide autour de l’ergot. According to another embodiment, the second connector comprises a lug having an oblong shape to prevent rotation of the guide around the lug.
L’attache peut être située sur une partie latérale de la calotte. The clip may be located on a side portion of the cap.

L’attache 5 est configurée pour relier les deux extrémités libres 3, 4 ensemble. L’attache 5 est dite à fermeture, car elle peut adopter un état fermé, illustré aux figures 3 à 6, dans lequel elle relie mécaniquement les deux extrémités libres 3, 4, et un état ouvert, illustré aux figures 1 et 2, dans lequel les extrémités libres 3,The fastener 5 is configured to connect the two free ends 3, 4 together. The fastener 5 is said to be closed because it can adopt a closed state, illustrated in FIGS. 3 to 6, in which it mechanically connects the two free ends 3, 4, and an open state, illustrated in FIGS. 1 and 2, in which the free ends 3,
4 ne sont plus reliées entre elles et sont libres de leur mouvement. Lorsque l’attache 5 occupe l’état fermé, on dit que le casque 1 est fermé, et lorsque l’attache 5 occupe l’état ouvert, on dit que le casque 1 est ouvert. 4 are no longer connected to each other and are free from their movement. When the fastener 5 occupies the closed state, it is said that the helmet 1 is closed, and when the fastener 5 occupies the open state, it is said that the helmet 1 is open.
En particulier, l’attache 5 est dite élastique. C’est-à-dire que l’attache 5 est configurée pour occuper une position écartée, depuis une position initiale, lors d’une sollicitation mécanique, notamment une poussée exercée par le crâne 6, et pour reprendre sa position initiale lorsque la sollicitation mécanique disparaît. L’attache 5 est élastique lorsqu’elle occupe l’état fermé. C’est-à-dire que lorsque l’attache 5 occupe son état fermé, les extrémités libres 3, 4 sont libres de se déplacer l’une par rapport à l’autre. A la différence des attaches de l’état de la technique qui sont verrouillées en maintenant une distance constante entre les deux extrémités libres, l’attache 5 selon l’invention, lorsqu’elle occupe un état fermé, l’attache 5 peut occuper des positions variées dans lesquelles la distance entre les extrémités libres varie. En d’autres termes, l’attache 5 est configurée pour exercer une force de rappel sur les deux extrémités libres 3, 4 de manière à les rapprocher l’une vers l’autre. En outre, l’attache 5 est configurée pour permettre un éloignement des deux extrémités libres 3, 4 l’une de l’autre lorsque le crâne 6 du nourrisson exerce une force de poussée supérieure à la force de rappel. In particular, the fastener 5 is called elastic. That is to say that the fastener 5 is configured to occupy a spaced position, from an initial position, during a mechanical stress, in particular a thrust exerted by the skull 6, and to resume its initial position when the solicitation mechanical disappears. The fastener 5 is elastic when it occupies the closed state. That is, when the fastener 5 is in its closed state, the free ends 3, 4 are free to move relative to each other. Unlike the fasteners of the state of the art which are locked by maintaining a constant distance between the two free ends, the fastener 5 according to the invention, when it occupies a closed state, the fastener 5 can occupy various positions in which the distance between the free ends varies. In other words, the fastener 5 is configured to exert a restoring force on the two free ends 3, 4 so as to bring them towards each other. In addition, the fastener 5 is configured to allow a distance of the two free ends 3, 4 of each other when the skull 6 of the infant exerts a thrust force greater than the restoring force.
Lorsque l’attache 5 occupe l’état fermé, comme illustré aux figures 3 à 6, elle relie mécaniquement les extrémités libres 3, 4 et le casque 1 est fermé. L’attacheWhen the fastener 5 occupies the closed state, as illustrated in FIGS. 3 to 6, it mechanically connects the free ends 3, 4 and the helmet 1 is closed. The clip
5 peut occuper une position initiale, illustrée à la figure 3, dans laquelle une distance initiale Di sépare les deux extrémités libres 3, 4. Par exemple la distance initiale Di peut être nulle. Lorsque le crâne 6 grandit, il exerce une force de poussée sur la calotte 2 et tend à écarter les extrémités libres 3, 4 l’une de l’autre. Dans ce cas, l’attache 5 occupe une position écartée, illustrée aux figures 4 à 6, dans laquelle une distance de séparation sépare les deux extrémités libres 3, 4. La distance de séparation est supérieure à la distance initiale Di. Lorsque l’attache 5 occupe une position écartée, elle reste dans l’état fermé, ce qui maintient le casque 1 sur le crâne 6 du nourrisson. En d’autres termes, dans la position écartée, l’attache 5 relie également mécaniquement les deux extrémités 3, 4 entre elles. Les deux extrémités 3, 4 se trouvent alors éloignées l’une de l’autre et sont séparées par la distance de séparation. En outre, l’attache 5 peut occuper une position maximum dans laquelle les extrémités libres 3, 4 sont reliées mécaniquement mais sont éloignées l’une de l’autre d’une distance maximum Dm dont la valeur correspond au maximum de la distance de séparation. 5 can occupy an initial position, illustrated in Figure 3, wherein an initial distance Di separates the two free ends 3, 4. For example the initial distance Di can be zero. When the skull 6 grows, it exerts a thrust force on the cap 2 and tends to spread the free ends 3, 4 of one another. In this case, the fastener 5 occupies a spaced position, illustrated in Figures 4 to 6, wherein a separation distance separates the two free ends 3, 4. The separation distance is greater than the initial distance Di. When the fastener 5 occupies a remote position, it remains in the closed state, which keeps the helmet 1 on the skull 6 of the infant. In other words, in the separated position, the fastener 5 also mechanically connects the two ends 3, 4 between them. The two ends 3, 4 are then separated from one another and are separated by the separation distance. In addition, the fastener 5 can occupy a maximum position in which the free ends 3, 4 are mechanically connected but are spaced from each other by a maximum distance Dm whose value corresponds to the maximum of the separation distance .
Par exemple, l’attache 5 comporte un premier connecteur 9 monté sur la première extrémité libre 3 et un deuxième connecteur 10 monté sur la deuxième extrémité libre 4. En outre, l’attache 5 comporte un moyen élastique 11 adapté pour être relié aux deux connecteurs 9, 10. Selon un mode de réalisation, le moyen élastique 11 est relié de manière amovible à un connecteur 9, 10. Ainsi, on peut retirer le moyen élastique 11 du connecteur 9, 10. Selon un autre mode de réalisation, le moyen élastique 11 est relié aux deux connecteurs 9, 10 de manière amovible. Ainsi on peut retirer le moyen élastique 11 des deux connecteurs 9, 10, comme illustré sur les figures 1 et 2. Dans les deux modes de réalisation, lorsqu’on retire le moyen élastique 11 d’au moins un connecteur 9, 10, les extrémités libres 3, 4 ne sont plus reliées mécaniquement entre elles et l’attache 5 occupe son état ouvert. Dans l’état ouvert, on peut écarter les extrémités 3, 4 au-delà de la distance maximum Dm, et faciliter la mise en place du casque 1 sur le crâne 6. For example, the fastener 5 comprises a first connector 9 mounted on the first free end 3 and a second connector 10 mounted on the second free end 4. In addition, the fastener 5 comprises an elastic means 11 adapted to be connected to both connectors 9, 10. According to one embodiment, the resilient means 11 is removably connected to a connector 9, 10. Thus, the elastic means 11 can be removed from the connector 9, 10. According to another embodiment, the elastic means 11 is connected to the two connectors 9, 10 removably. Thus, the elastic means 11 can be removed from the two connectors 9, 10, as illustrated in FIGS. 1 and 2. In both embodiments, when the elastic means 11 are removed from at least one connector 9, 10, the free ends 3, 4 are no longer mechanically connected to each other and the fastener 5 occupies its open state. In the open state, one can spread the ends 3, 4 beyond the maximum distance Dm, and facilitate the introduction of the helmet 1 on the skull 6.
Avantageusement, le moyen élastique 11 est relié de manière fixe à au moins un connecteur 9, 10. C’est-à-dire que le moyen élastique 11 est fixé de manière permanente à au moins un connecteur 9, 10. Dans ce cas, on peut écarter les extrémités 3, 4 au-delà de la distance maximum Dm, sans risque de perdre le moyen élastique 11. Selon un autre avantage, le moyen élastique 11 peut être relié de manière fixe aux deux connecteurs 9, 10. Dans ce cas, l’écartement maximum des extrémités libres 3, 4 correspond à la distance maximum Dm. Par exemple, le moyen élastique 11 peut être un élastique ayant une forme filaire en boucle fermée, comme illustré sur les figures 3 à 6. Advantageously, the resilient means 11 is fixedly connected to at least one connector 9, 10. That is to say that the elastic means 11 is permanently fixed to at least one connector 9, 10. In this case, the ends 3, 4 can be spread beyond the maximum distance Dm, without the risk of losing the elastic means 11. According to another advantage, the elastic means 11 can be fixedly connected to the two connectors 9, 10. case, the maximum spacing of the free ends 3, 4 corresponds to the maximum distance Dm. By For example, the resilient means 11 may be an elastic having a closed-loop wired form, as illustrated in FIGS. 3 to 6.
Les connecteurs 9, 10 peuvent en outre comporter respectivement deux butées 12, 13 destinées à être reliées au moyen élastique 11. L’élastique 11 est placé autour des butées 12 ,13 et génère une force de rappel lorsqu’on écarte les deux extrémités 3, 4 l’une de l’autre. La force de rappel tend à rapprocher les extrémités 3, 4 l’une vers l’autre lorsque la sollicitation d’écartement des extrémités 3, 4 disparaît ou devient inférieure à la force de rappel. Par ailleurs, le premier connecteur 9 comporte un guide 14 se prolongeant en direction de la deuxième extrémité libre 4. C’est-à-dire que le guide 14 est saillant par rapport à l’extrémité libre 3 sur laquelle il est monté. Le guide 14 s’étend longitudinalement le long d’une courbe, il a une forme allongée. Le guide 14 est destiné à guider l’écartement et le rapprochement des extrémités libres 3, 4 lorsque celles-ci sont en mouvement relatif l’une par rapport à l’autre. The connectors 9, 10 may further comprise respectively two stops 12, 13 intended to be connected to the elastic means 11. The elastic 11 is placed around the stops 12, 13 and generates a restoring force when the two ends are separated 3 , 4 from each other. The return force tends to bring the ends 3, 4 towards each other when the biasing stress of the ends 3, 4 disappears or becomes less than the restoring force. Furthermore, the first connector 9 comprises a guide 14 extending towards the second free end 4. That is to say that the guide 14 is projecting relative to the free end 3 on which it is mounted. The guide 14 extends longitudinally along a curve, it has an elongated shape. The guide 14 is intended to guide the spacing and the approximation of the free ends 3, 4 when they are in relative movement relative to each other.
En outre, le deuxième connecteur 10 comporte au moins un ergot 15 conformé pour coopérer avec le guide 14 de manière à permettre un déplacement des deux extrémités libres 3, 4 le long du guide 14. In addition, the second connector 10 comprises at least one lug 15 shaped to cooperate with the guide 14 so as to allow movement of the two free ends 3, 4 along the guide 14.
Un orifice allongé 16 peut être formé dans le guide 14. L’orifice 16 est conformé pour recevoir un ergot 15 qui coulisse dans l’orifice 16. Par exemple, l’ergot 15 peut avoir une forme oblongue pour empêcher une rotation du guide 14 autour de l’ergot 15. En variante, le deuxième connecteur 10 comporte deux ergots ayant chacun une forme cylindrique. On entend par cylindre, un solide limité par une surface cylindrique engendrée par un ensemble de droites parallèles, notées génératrices, s’appuyant sur une courbe plane fermée, notée directrice, et deux plans coupant les génératrices. Les deux ergots sont espacés l’un de l’autre et placés sur le deuxième connecteur 10 dans le prolongement du guide 14. Les deux ergots cylindriques permettent d’empêcher une rotation du guide 14 autour d’un des deux ergots. Les deux ergots cylindriques, ou l’ergot 15 oblong, garantissent un déplacement des extrémités 3, 4 dans le prolongement du guide 14. An elongate orifice 16 may be formed in the guide 14. The orifice 16 is shaped to receive a lug 15 which slides in the orifice 16. For example, the lug 15 may have an oblong shape to prevent rotation of the guide 14 around the lug 15. Alternatively, the second connector 10 has two lugs each having a cylindrical shape. By cylinder is meant a solid bounded by a cylindrical surface generated by a set of parallel straight lines, denoted generators, based on a closed planar curve, denoted as a director, and two planes intersecting the generatrices. The two lugs are spaced from each other and placed on the second connector 10 in the extension of the guide 14. The two cylindrical lugs can prevent rotation of the guide 14 around one of the two lugs. The two cylindrical lugs, or the oblong lug, guarantee a displacement of the ends 3, 4 in the extension of the guide 14.
Une telle attache 5 a l’avantage d’être silencieuse, c’est-à-dire qu’elle permet un mouvement silencieux des extrémités 3, 4. Such a fastener 5 has the advantage of being silent, that is to say it allows silent movement of the ends 3, 4.
L’orifice 16 peut recevoir une pièce supplémentaire placée entre la première extrémité 3 et l’ergot 15, pour empêcher un serrage du crâne 6 lorsque le nourrisson grandit. Par exemple, la pièce supplémentaire est placée au sein de l’orifice 16 du guide 14, entre l’ergot 15 et la première butée 12. La pièce supplémentaire fait office de cale, et elle permet d’augmenter la distance initiale Di. The orifice 16 may receive an additional piece placed between the first end 3 and the lug 15, to prevent tightening of the skull 6 when the infant is growing up. For example, the additional piece is placed within the orifice 16 of the guide 14, between the lug 15 and the first stop 12. The additional piece serves as a shim, and it allows to increase the initial distance Di.
De préférence, l’attache 5 est située sur une partie latérale de la calotte 2. En effet, la croissance du crâne 6 dans un plan transverse du nourrisson, c’est-à- dire un plan horizontal qui sépare le corps en une partie supérieure (qui contient la tête) et une partie inférieure (qui contient les pieds), est plus rapide que la croissance dans l’axe cranio-caudal (l’axe passant du crâne aux pieds), c’est-à- dire un axe perpendiculaire au plan transverse. L’orifice supérieur 7 permet une poussée de croissance de la boîte crânienne selon l’axe cranio-caudal. Preferably, the fastener 5 is located on a lateral portion of the cap 2. Indeed, the growth of the skull 6 in a transverse plane of the infant, that is to say a horizontal plane which separates the body into a part superior (which contains the head) and a lower part (which contains the feet), is faster than the growth in the cranio-caudal axis (the axis passing from the skull to the feet), that is to say a axis perpendicular to the transverse plane. The upper orifice 7 allows growth of growth of the cranial box along the cranio-caudal axis.
Un tel casque possède une fermeture facile à manipuler, il est particulièrement adapté à la croissance du crâne car il permet de corriger une déformation sans avoir à effectuer un réglage manuel sur le casque. Such a helmet has a closure easy to handle, it is particularly suitable for the growth of the skull as it corrects a deformation without having to perform a manual adjustment on the helmet.
