Description

Dispositif de positionnement d'un élément de protection et/ou filtrant Positioning device for a protective and / or filter element
Le domaine technique de la présente invention est celui des moyens de filtration des particules en suspension dans l'air respiré et de protection d'une partie du corps .The technical field of the present invention is that of means for filtering particles in suspension in the breathed air and for protecting a part of the body.
On sait que pour filtrer des particules en suspension dans l'air, il est connu d'introduire dans le nez d'un patient des éléments assurant la filtration de ces particules. Ainsi, le brevet WO 95/33520 décrit un dispositif de filtration comportant une armature en forme de monture réalisée à base de caoutchouc ou de matériau plastique, délimitant un cadre dans lequel un élément filtrant est inséré. Ce dispositif est difficilement tolérable par la peau et doit être adapté à la morphologie du patient.It is known that in order to filter particles in suspension in the air, it is known to introduce into the nose of a patient elements ensuring the filtration of these particles. Thus, patent WO 95/33520 describes a filtration device comprising a frame in the form of a frame made from rubber or plastic material, delimiting a frame in which a filter element is inserted. This device is hardly tolerable by the skin and must be adapted to the patient's morphology.
Le brevet CH-A-662 742 décrit un gousset fermé par deux parois et rempli de granulés absorbant les gaz. Ce gousset est incorporé dans chacune des narines d'un patient.Patent CH-A-662,742 describes a gusset closed by two walls and filled with gas-absorbing granules. This gusset is incorporated into each of a patient's nostrils.
Le brevet US-A-3 802 426 décrit un filtre nasal constitué d'une barrette dont les extrémités sont munies d'un filtre constitué par un ensemble de fils, éventuellement imprégnés de médicaments.US-A-3,802,426 describes a nasal filter consisting of a bar, the ends of which are provided with a filter constituted by a set of wires, possibly impregnated with medicaments.
Le brevet US-A-4 267 831 décrit un filtre nasal composé de deux éléments cylindriques, en papier ou matière plastique, dans lesquels un matériau filtrant est incorporé.US-A-4 267 831 describes a nasal filter composed of two cylindrical elements, of paper or plastic, in which a filter material is incorporated.
Ce matériau est constitué de coton, de laine, de feutre, ou de mousse synthétique saturée à l'aide d'un médicament.This material is made of cotton, wool, felt, or synthetic foam saturated with a drug.
Le brevet CH-A-97 538 décrit un filtre nasal constitué d'une monture comprenant une pièce en U aux extrémités duquel sont fixés des cercles support d'un filtre de gaze ou de coton, éventuellement imprégné de médicaments.Patent CH-A-97 538 describes a nasal filter consisting of a frame comprising a U-shaped piece at the ends of which are fixed support circles for a gauze or cotton filter, possibly impregnated with medicaments.
Dans tous les filtres décrits dans ces documents, on retrouve le même principe à savoir une monture sensiblement rigide entourant un filtre. Cette structure n'est pas commode à réaliser et de plus implique une intervention particulière pour fixer ou incorporer l'élément filtrant. De plus, ces dispositifs ne peuvent pas être utilisés comme moyen de protection d'une plaie. On sait que pour éviter qu'une plaie soit à l'air libre il faut appliquer une protection consistant à recouvrir celle-ci à l'aide de tampon de gaze. L'inconvénient de cette manière de faire réside dans le fait que la plaie est en contact avec un corps étranger.In all the filters described in these documents, the same principle is found, namely a substantially rigid frame surrounding a filter. This structure is not easy to produce and moreover requires special intervention to fix or incorporate the filter element. In addition, these devices cannot be used as a means of protecting a wound. We know that to avoid a wound being in the open air, we must apply a protection consisting of covering it with a gauze pad. The disadvantage of this procedure is that the wound is in contact with a foreign body.
Le but de la présente invention est de fournir un dispositif de positionnement très simple à réaliser dans lequel l'interposition de l'élément de protection et/ou filtrant dans son support est très facile à mettre en œuvre.The object of the present invention is to provide a positioning device which is very simple to produce in which the interposition of the protective and / or filtering element in its support is very easy to implement.
L'invention a donc pour objet un dispositif de positionnement d'un élément de protection et/ou filtrant à distance d'une partie corporelle d'un patient, caractérisé en ce qu'il est constitué d'un support sensiblement rigide muni de deux perforations pratiquées par rapport à une ligne de pliage pour délimiter deux volets, les perforations étant destinées à recevoir l'élément de protection et/ou filtrant lorsque les volets sont rabattus l'un sur l'autre suivant ladite ligne de pliage. Selon une caractéristique de l'invention, les perforations sont pratiquées symétriquement par rapport à la ligne de pliage.The subject of the invention is therefore a device for positioning a protective and / or filtering element at a distance from a body part of a patient, characterized in that it consists of a substantially rigid support provided with two perforations made with respect to a fold line to delimit two flaps, the perforations being intended to receive the protective and / or filtering element when the flaps are folded over one another along said fold line. According to a characteristic of the invention, the perforations are made symmetrically with respect to the fold line.
Selon une autre caractéristique de l'invention, l'élément de protection se présente sous la forme d'une lingette micro-aérée et est imbibé d'une substance odorante, médicamenteuse ou cosmétique.According to another characteristic of the invention, the protective element is in the form of a micro-aerated wipe and is soaked with an odorous, medicinal or cosmetic substance.
Selon encore une autre caractéristique de l'invention/ le support se présente sous la forme d'un tissu sensiblement rigide ayant une épaisseur de l'ordre de 2 à 10 mm.According to yet another characteristic of the invention / the support is in the form of a substantially rigid fabric having a thickness of the order of 2 to 10 mm.
Selon une autre caractéristique de l'invention, le support est muni de bandelettes de fixation pour son maintien par rapport à la partie corporelle du patient.According to another characteristic of the invention, the support is provided with fixing strips for its maintenance relative to the body part of the patient.
Selon une variante de réalisation de l'invention, le support se présente à l'état replié sous la forme d'une monture comportant deux éléments de protection.According to an alternative embodiment of the invention, the support is in the folded state in the form of a frame comprising two protective elements.
La monture se présente sous la forme de deux éléments arrondis réunis par un bras de liaison.The frame is in the form of two elements rounded joined by a link arm.
La monture est obtenue à partir d'une toile souple et flexible enduite de substance adhésive naturelle hypoallergénique, par exemple du coton. Les éléments de protection sont en coton tissé et aéré constituant des moyens de filtration et imprégnés de substances odorantes.The frame is obtained from a flexible and flexible canvas coated with hypoallergenic natural adhesive substance, for example cotton. The protective elements are made of woven and ventilated cotton constituting filtration means and impregnated with odorous substances.
Selon encore une autre caractéristique, le support est conformé pour que la monture s'adapte dans les narines d'un patient.According to yet another characteristic, the support is shaped so that the frame fits in the nostrils of a patient.
Un tout premier avantage du dispositif selon l'invention réside dans sa simplicité de réalisation.A very first advantage of the device according to the invention lies in its simplicity of construction.
Un autre avantage réside dans le fait que la fabrication peut être entièrement automatisée. D'autres caractéristiques, détails et avantages de 1 ' invention ressortiront plus clairement de la description donnée ci-après à titre indicatif en relation avec des dessins dans lesquels :Another advantage is that the manufacturing can be fully automated. Other characteristics, details and advantages of the invention will emerge more clearly from the description given below by way of indication in relation to the drawings in which:
- la figure 1 montre la phase initiale de fabrication d'un exemple de réalisation d'un dispositif de protection,FIG. 1 shows the initial manufacturing phase of an exemplary embodiment of a protection device,
- la figure 2 représente le dispositif de protection prêt à l'emploi,FIG. 2 represents the protection device ready for use,
- la figure 3 est une coupe transversale du dispositif de la figure 2, - la figure 4 montre la phase initiale de fabrication d'un autre exemple de réalisation d'un dispositif filtrant,- Figure 3 is a cross section of the device of Figure 2, - Figure 4 shows the initial manufacturing phase of another embodiment of a filter device,
- la figure 5 représente le dispositif filtrant prêt à l' emploi,FIG. 5 represents the filtering device ready for use,
- la figure 6 représente une coupe transversale selon AA de la figure 5, et la figure 7 représente une autre variante de réalisation du support.- Figure 6 shows a cross section along AA of Figure 5, and Figure 7 shows another alternative embodiment of the support.
Sur la figure 1, on a représenté un support 1 définissant une ligne de pliage 2 le long de laquelle ses deux volets 3 et 4 peuvent être repliés l'un sur l'autre.In Figure 1, there is shown a support 1 defining a fold line 2 along which its two flaps 3 and 4 can be folded over one another.
Chaque volet est ajouré de manière sensiblement symétrique par rapport à la ligne de pliage 2 pour délimiter des perforations 5 et 6. Sur le volet 3 par exemple, on applique une bande constituant un élément de protection 7 au niveau de la perforation 6 de manière à la fermer complètement. Puis, on rabat suivant la ligne de pliage 8 le volet 4 contre le volet 3 préalablement enduit de colle, par exemple une colle naturelle hypoallergénique. A titre d'exemple, le support 1 peut être réalisé en toile adhésive 100% coton suffisamment souple et flexible. Ce support 1 est d'une épaisseur telle qu'il permet de maintenir un écart suffisant entre la peau et l'élément de protection. Une épaisseur de l'ordre de 2 à 10 mm, et préférentiellement 4 mm, est suffisante. La matière consituant le support peut être également un produit vendu sous la marque commerciale STYLEX de forte épaisseur, 10 cm par exeple. On peut donc envisager une utilisation à titre préventif. L'élément de protection 7 est réalisé sous forme de lingette micro aérée. Cet élément 7 peut être enduit de substances médicamenteuses, odorantes, cosmétiques soit au cours de la fabrication, soit par le patient lui-même au moment de l'utilisation.Each flap is perforated in a substantially symmetrical manner relative to the fold line 2 to delimit perforations 5 and 6. On the flap 3 for example, a strip is applied constituting a protective element 7 at the perforation 6 so as to completely close it. Then, the flap 4 is folded along the fold line 8 against the flap 3 previously coated with glue, for example a hypoallergenic natural glue. For example, the support 1 can be made of 100% cotton adhesive fabric which is sufficiently supple and flexible. This support 1 is of a thickness such that it allows a sufficient distance to be maintained between the skin and the protective element. A thickness of the order of 2 to 10 mm, and preferably 4 mm, is sufficient. The material constituting the support can also be a product sold under the very thick STYLEX trademark, 10 cm for example. We can therefore consider a preventive use. The protective element 7 is produced in the form of a micro-aerated wipe. This element 7 can be coated with medicinal, odorous, cosmetic substances either during manufacture, or by the patient himself at the time of use.
Sur la figure 2, on a représenté le dispositif de protection destiné à la protection d'une plaie selon lequel le support 1 est muni de part et d' autre d' une bande collante 9 pour être fixée sur la peau. On obtient ainsi un support suffisamment rigide pour être appliqué sur la peau d'un patient à distance d'une plaie et permettre de cette manière une guérison plus rapide. Il va sans dire que le support 1 peut être découpé pour épouser la forme du pavillon de l'oreille d'un patient si on souhaite la protéger. Il est alors maintenu en place par son galbe et sa flexibilité. Le dispositif de protection peut être également utilisé au niveau des doigts, des orteils en étant un simple écarteur et au niveau des yeux. Le dispositif peut se présenter sous la forme d'un fourreau apte à épouser la forme d'un doigt par exemple afin de ne pas gêner les mouvements de ce doigt. Ainsi, ce doigt est protégé totalement des impuretés et la guérison est donc améliorée.In Figure 2, there is shown the protective device for the protection of a wound according to which the support 1 is provided on either side with a sticky strip 9 to be fixed on the skin. A support is thus obtained which is sufficiently rigid to be applied to the skin of a patient at a distance from a wound and in this way allow faster healing. It goes without saying that the support 1 can be cut to match the shape of the pavilion of a patient's ear if it is desired to protect it. It is then held in place by its curve and flexibility. The protective device can also be used at the level of the fingers, the toes by being a simple retractor and at the level of the eyes. The device may be in the form of a sheath capable of marrying the shape of a finger for example so as not to hinder the movements of this finger. So this finger is completely protected from impurities and healing is therefore improved.
Le dispositif de protection peut être enduit d'un gel spécifique d' extraction des épines et apposer pour éviter toute compression de la partie douloureuse. Sur la figure 3, on a représenté une coupe AA selon la figure 2 où l'on voit le support 1 constitué des deux volets 3 et 4 collés l'un contre l'autre emprisonnant l'élément 7 au niveau de sa périphérie. Le support 1 est muni au niveau de ses extrémités de deux bandes de colle 9 lorsqu'on souhaite protéger une plaie corporelle. Il peut être muni de bandelettes pour l'attacher au patient ou d'une attache type Velcro, marque déposée.The protection device can be coated with a specific gel for extracting the thorns and affixed to avoid any compression of the painful part. In Figure 3, there is shown a section AA according to Figure 2 where we see the support 1 consisting of two flaps 3 and 4 glued against one another trapping the element 7 at its periphery. The support 1 is provided at its ends with two strips of glue 9 when it is desired to protect a bodily wound. It can be fitted with strips to attach it to the patient or with a Velcro type fastener, registered trademark.
L'élément 7 peut être un autocollant servant d'adhésif. Sur les figures 1, 2 et 3, on a représenté des perforations 5 circulaires. Il va sans dire que celle-ci peuvent être de forme quelconque, par exemple sous forme d'un cœur, d'une étoile. Le support peut être agrémenté de dessins de fantaisie, éventuellement détachables, des décalcomanis par exemple, ces éléments ayant une fonction esthétique.The element 7 can be a sticker serving as an adhesive. In Figures 1, 2 and 3, there are shown circular perforations 5. It goes without saying that these can be of any shape, for example in the form of a heart, a star. The support can be embellished with fancy designs, possibly detachable, for example decals, these elements having an aesthetic function.
La variante de réalisation représentée sur la figure 4 est destinée à supporter deux éléments filtrants pour être introduite dans le nez d'un patient afin de filtrer les particules du type pollen ou autres . Elle comporte un support 10 se présentant sous la forme d'une toile adhésive stérilisée 100% coton comportant deux volets 11 et 12 repliables l'un sur l'autre suivant la ligne de pliage 13. Chaque volet 11 ou 12 est muni de deux perforations 14 et 15 ou 16 et 17 disposées à distance l'une de l'autre et à proximité immédiate de la ligne de pliage 13. On applique au niveau de chacune des perforations 16 et 17 du volet 11 un élément filtrant 18 ou 19 en recouvrement du bord des perforations 16 et 17. Un élément filtrant peut en variante être appliqué au niveau de chaque perforation. On rabat ensuite le volet 12 enduit de colle contre le volet 11 suivant la ligne de pliage 13 en s' arrangeant pour faire correspondre les perforations 14 et 16 d'une part et les perforations 15 et 17 d'autre part. La colle est du type naturel hypoallergénique. Sur la figure, on a représenté deux éléments filtrants sous forme carrée à coins arrondis. Il va sans dire que cette forme est donnée à titre d'exemple et qu'on peut adopter une forme quelconque. Sur la figure, on a représenté également une ligne 20 suivant laquelle on peut découper le support 10 afin de lui donner une forme particulière. Cette forme peut être adaptée à la morphologie du patient par simple découpe. Sur la figure 5, on a représenté un dispositif apte à être introduit dans le nez d'un patient en vue de la filtration des particules en suspension dans l'air. Ce dispositif est obtenu après pliage du support 10 et découpe de l'ensemble suivant la ligne 20 de la figure 4. Après pliage du volet 12 sur le volet 11, on obtient une monture 21 constituée de deux ailes 22 et 23 sous forme d'éléments arrondis enserrant les deux éléments filtrants 18 et 19. Les dimensions de ce dispositif sont telles qu'il puisse être introduit dans les narines et maintenu en place par simple flexibilité. Dans cette configuration, le dispositif n' est fixé par aucune substance adhésive qui adhère à la peau et est entièrement stérilisé. Il est insensible pour le patient, discret et jetable. Il s'adapte à la forme des fosses nasales et limite ainsi l'entrée des particules microscopiques polluantes et du pollen. Bien entendu, on peut prévoir différentes dimensions en fonction de celles de la cavité nasale des patients. Ces différentes dimensions peuvent être repérées sur la monture à l' aide d'un pointillé. Comme précédemment, les éléments 18 et 19 sont constitués de gaze stérilisée, de coton tissé en armure sous forme de compresse ou éventuellement d'une lingette aérée stérilisée. De plus, ces éléments pourront être odorants pour mieux faciliter la respiration avec par exemple du parfum, des extraits de plantes médicinales utilisées dans les préparations pour inhalation. Ces éléments peuvent être également enduits d'une substance collante pour retenir les particules microscopiques et empêcher leur entrée dans les fosses nasales.The variant embodiment shown in FIG. 4 is intended to support two filter elements to be introduced into the nose of a patient in order to filter particles of the pollen or other type. It comprises a support 10 in the form of a sterilized 100% cotton adhesive fabric comprising two flaps 11 and 12 which can be folded one on the other along the fold line 13. Each flap 11 or 12 is provided with two perforations 14 and 15 or 16 and 17 arranged at a distance from each other and in the immediate vicinity of the fold line 13. A filter element 18 or 19 is applied to each of the perforations 16 and 17 of the flap 11 from the edge of the perforations 16 and 17. A filter element may alternatively be applied at the level of each perforation. Then fold the flap 12 coated with adhesive against the flap 11 along the fold line 13 by arranging to match the perforations 14 and 16 on the one hand and the perforations 15 and 17 on the other hand. The glue is of the natural hypoallergenic type. In the figure, two filter elements are shown in square form with rounded corners. It goes without saying that this form is given by way of example and that any form can be adopted. In the figure, there is also shown a line 20 along which the support 10 can be cut in order to give it a particular shape. This shape can be adapted to the patient's morphology by simple cutting. In Figure 5, there is shown a device adapted to be introduced into the nose of a patient for the filtration of airborne particles. This device is obtained after folding the support 10 and cutting the assembly along line 20 of FIG. 4. After folding the flap 12 on the flap 11, a frame 21 is obtained consisting of two wings 22 and 23 in the form of rounded elements enclosing the two filter elements 18 and 19. The dimensions of this device are such that it can be introduced into the nostrils and held in place by simple flexibility. In this configuration, the device is not fixed by any adhesive substance which adheres to the skin and is completely sterilized. It is insensitive to the patient, discreet and disposable. It adapts to the shape of the nasal cavity and thus limits the entry of microscopic polluting particles and pollen. Of course, different dimensions can be provided depending on those of the patient's nasal cavity. These different dimensions can be identified on the frame using a dotted line. As before, the elements 18 and 19 consist of sterilized gauze, cotton woven in weave in the form of a compress or possibly a sterile aerated wipe. In addition, these elements may be fragrant to better facilitate breathing with for example perfume, extracts of medicinal plants used in preparations for inhalation. These elements can also be coated with a sticky substance to retain microscopic particles and prevent their entry into the nasal cavity.
Sur la figure 6, on a représenté une coupe BB de la figure 5 montrant la disposition des éléments filtrants 18 et 19 en épaisseur maintenus par le support 10. On voit sur cette figure que la partie médiane 24 du support est un bras d'une largeur telle qu'elle s'adapte à la base du nez. Ce bras est de dimension faible, 4 mm de large par exemple, et d'une couleur semblable à celle de la peau du patient. Il est quasiment invisible. Ce dispositif peut être livré en pochette ou sous film protecteur que l'on pourra retirer avant la mise en place. Pour placer ce dispositif dans les narines, il suffit d'appliquer la partie médiane 24 à la base du nez et exercer une simple pression entre le pouce et l'index sur les bords extrêmes du dispositif et l'introduire dans les narines du patient. En reprenant sa forme initiale, le dispositif est bloqué dans les narines. Pour l'extraire, on exerce une pression de chaque côté de l'arête du nez avec le pouce et l'index entraînant une pliure de la partie médiane 24.In Figure 6, there is shown a section BB of Figure 5 showing the arrangement of the filter elements 18 and 19 in thickness maintained by the support 10. We see in this figure that the middle part 24 of the support is an arm of a width as it fits the base of the nose. This arm is of small size, 4 mm wide for example, and a color similar to that of the patient's skin. It is almost invisible. This device can be delivered in a pouch or in a protective film that can be removed before installation. To place this device in the nostrils, simply apply the middle part 24 to the base of the nose and exert a simple pressure between the thumb and forefinger on the extreme edges of the device and introduce it into the patient's nostrils. Returning to its original shape, the device is blocked in the nostrils. To extract it, pressure is exerted on each side of the bridge of the nose with the thumb and forefinger, causing the middle part to bend 24.
Sur la figure 7, on a représenté une variante de réalisation de l'invention selon laquelle l'élément de protection 7 est disposé sur les deux volets du support en recouvrement des perforations. On étale ensuite le produit cosmétique, médicamenteux ou odorant sur l'élément et lorsque le support est replié, on replie en même temps l'élément, ce qui permet d'obtenir une enveloppe renfermant le produit. Cette réalisation permet d'augmenter la durée de diffusion du produit lorsque son utilisation le nécessite. In Figure 7, there is shown an alternative embodiment of the invention according to which the protective element 7 is arranged on the two flaps of the support covering the perforations. The cosmetic, medicinal or odorous product is then spread over the element and when the support is folded, the element is folded at the same time, which makes it possible to obtain an envelope containing the product. This embodiment makes it possible to increase the duration of diffusion of the product when its use requires it.
