Description

DISPOSITIF DE MATELAS A DECOMPRESSION MODULAIRE, STATIQUE OU MODULAR, STATIC OR DECOMPRESSION MATTRESS DEVICE
DYNAMIQUE DYNAMIC
La présente invention a pour objet un dispositif matelas à décompression modulaire, statique ou dynamique. The present invention relates to a mattress device with modular, static or dynamic decompression.
Un tel matelas est destiné à être préférentiellement, mais non exclusivement, utilisé dans le domaine hospitalier afin d'éviter la formation des escarres et/ou pour faire prendre à l'utilisateur une posture particulière, ou bien une succession de posture particulières différentes. Such a mattress is intended to be preferably, but not exclusively, used in the hospital field in order to prevent the formation of bedsores and / or to make the user assume a particular posture, or else a succession of different particular postures.
Parmi les plus performants, on connaît par les documents FR 2 953 387 et FR 2 928 250 au nom de la demanderesse des matelas gonflables statiques ou dynamiques, comprenant un ou plusieurs ensembles de cellules gonflables à basse pression réglable, associé à des moyens de gonflage et de gestion de pression permettant de gonfler ou de dégonfler, simultanément et/ou en alternance, une ou plusieurs desdites cellules, permettant, par des opérations de gonflage et dégonflage en alternance, de générer un mouvement de balancement. Among the most efficient, we know from documents FR 2 953 387 and FR 2 928 250 in the name of the applicant static or dynamic inflatable mattresses, comprising one or more sets of inflatable cells at adjustable low pressure, associated with inflation means. and pressure management making it possible to inflate or deflate, simultaneously and / or alternately, one or more of said cells, allowing, by alternating inflation and deflation operations, to generate a rocking movement.
De manière avantageuse, ces matelas comportent plusieurs zones distinctes comportant des juxtapositions de coussins, amovibles individuellement, qui s'étendent selon une direction transversale sensiblement perpendiculaire à la direction longitudinale générale du matelas, ou bien parallèlement à ladite direction longitudinale. Advantageously, these mattresses include several distinct zones comprising juxtapositions of individually removable cushions which extend in a transverse direction substantially perpendicular to the general longitudinal direction of the mattress, or else parallel to said longitudinal direction.
Les cellules de ces matelas sont liées entre elles et/ou reliées individuellement ou par blocs, à des moyens de gonflage et de gestion de pression au travers d'un ensemble de tuyaux, en sorte de créer un ensemble cohérent. S'il est possible de composer un matelas sur mesure, aux caractéristiques du patient, avant sont utilisation, la présence des nombreux tuyaux et raccordements rend difficile, voire impossible, la modification de la composition du matelas après sa mise en fonction. The cells of these mattresses are linked together and / or linked individually or in blocks, to means of inflation and pressure management through a set of pipes, so as to create a coherent whole. While it is possible to compose a custom-made mattress, according to the characteristics of the patient, before use, the presence of numerous pipes and connections makes it difficult, if not impossible, to modify the composition of the mattress after it has been put into operation.
On connaît les documents US 3 042 941, US 6 151 735 et US 6 912 748, relatifs à des matelas gonflables, comprenant une pompe intégrée, constituée d'une cellule renfermant un élément compressible à mémoire de forme, et associée à des valves en sorte de permettre le gonflement de cellules annexes . Ces documents ne permettent toutefois pas de réaliser un matelas à décompression modulaire. The documents US 3,042,941, US 6,151,735 and US 6,912,748 are known, relating to inflatable mattresses, comprising an integrated pump, consisting of a cell containing a compressible shape memory element, and associated with valves in sort of allowing the swelling of annex cells. However, these documents do not make it possible to produce a modular decompression mattress.
La présente invention a pour but de remédier aux inconvénients précités, en proposant un dispositif de matelas à décompression modulaire, statique ou dynamique, ne nécessitant pas d' être raccordé à des moyens de gonflage et de gestion de pression au travers de tuyaux. The object of the present invention is to remedy the aforementioned drawbacks, by proposing a modular, static or dynamic decompression mattress device which does not need to be connected to means of inflation and pressure management through pipes.
Le dispositif de matelas à décompression modulaire, statique ou dynamique selon l'invention, se caractérise en ce qu'il comprend dans une housse, une juxtaposition de cellules gonflables, comprenant chacune une enveloppe étanche, et munie chacune d'au moins deux valves unidirectionnelles à débit contrôlé, dont l'une est adaptée à l'extraction de l'air tandis que l'autre est adaptée à l'introduction de l'air, et en ce que ladite enveloppe comporte intérieurement au moins un bloc de mousse ou analogue, susceptible d'une part de se déformer sous l'action d'un appui sur ladite cellule en sorte de provoquer le dégonflement de ladite enveloppe, et d'autre part de reprendre sa forme hors appui en sorte de provoquer le gonflement de ladite enveloppe par aspiration. The modular, static or dynamic decompression mattress device according to the invention is characterized in that it comprises in a cover, a juxtaposition of inflatable cells, each comprising a sealed envelope, and each provided with at least two unidirectional valves at a controlled flow rate, one of which is adapted to the extraction of air while the other is adapted to the introduction of air, and in that said envelope has internally at least one block of foam or the like , capable on the one hand of being deformed under the action of pressing on said cell so as to cause deflation of said envelope, and on the other hand of resuming its shape without support so as to cause swelling of said envelope by aspiration.
Lors d'un appui sur une cellule, par une partie du corps, la cellule se dégonfle progressivement au rythme du débit contrôlé de la valve d'extraction, et le bloc de mousse s'écrase également. Lorsqu'il n'y a plus d'appui, le bloc de mousse reprend sa forme et entraîne dans sa reprise de forme la cellule qui se regonfle au rythme du débit contrôlé de la valve d'introduction. On obtient ainsi un dégonflement/regonflement de la cellule en fonction de la sollicitation extérieure. When pressing on a cell, by a part of the body, the cell gradually deflates at the rate of the controlled flow rate of the extraction valve, and the foam block also crashes. When there is no longer any support, the foam block returns to its shape and, in its resumption of shape, drives the cell which re-inflates at the rate of the controlled flow rate of the introduction valve. A deflation / re-inflation of the cell is thus obtained as a function of the external stress.
Selon une caractéristique additionnelle du dispositif de matelas selon l'invention, les valves sont positionnées au niveau d' une extrémité de chaque cellule . According to an additional characteristic of the mattress device according to the invention, the valves are positioned at one end of each cell.
Cela permet de s'affranchir des risques de bouchage des valves par l'utilisateur couché sur le matelas. This eliminates the risk of plugging the valves by the user lying on the mattress.
Selon une autre caractéristique additionnelle du dispositif de matelas selon l'invention, les cellules présentent des sections transversales de formes irrégulières . Ainsi, les cellules peuvent présenter, non limitativement, une section ronde, ovale, carrée, rectangulaire etc. Cela permet, par exemple, selon la nécessité de les positionner dans le dispositif de matelas, les cellules sur un côté ou un autre selon les besoins, pour faire une saillie ou un creux par exemple, et cela à tout moment puisqu'il n'y a pas de tuyaux susceptibles d'entraver les déplacements de la cellule. According to another additional characteristic of the mattress device according to the invention, the cells have cross sections of irregular shapes. Thus, the cells can have, without limitation, a round, oval, square, rectangular, etc. section. This allows, for example, according to the need to position them in the mattress device, the cells on one side or another as needed, to make a protrusion or a hollow for example, and this at any time since it does not there are no pipes likely to hinder the movements of the cell.
Selon une autre caractéristique additionnelle du dispositif de matelas selon l'invention, chaque enveloppe est fermée par une fermeture de type zip étanche. According to another additional characteristic of the mattress device according to the invention, each envelope is closed by a sealed zip type closure.
Les enveloppes, qui de préférence sont réalisées dans une matière plastique de type nylon, peuvent être fermées, après introduction du ou des blocs de mousse, par une opération de soudure, il est toutefois préféré une fermeture de type zip étanche, pour permettre le remplacement du ou des blocs si nécessaire . The envelopes, which are preferably made of a nylon-type plastic material, can be closed, after introduction of the foam block (s), by a welding operation, however, a sealed zip-type closure is preferred, to allow replacement. block (s) if necessary.
Selon une autre caractéristique additionnelle du dispositif de matelas selon l'invention, le ou les blocs de mousse ou analogue présente en surface des reliefs particuliers, différents d'un côté par rapport à un autre, chacun dédié à une fonction particulière. According to another additional characteristic of the mattress device according to the invention, the block or blocks of foam or the like has particular reliefs on the surface, different on one side with respect to another, each dedicated to a particular function.
Il est ainsi possible qu'un côté d'une cellule soit plan, tandis qu'un autre par exemple soit échancré dans le sens transversal, pour créer un calage latéral. It is thus possible that one side of a cell is flat, while another, for example, is notched in the transverse direction, to create a lateral wedging.
Les cellules sont disposées transversalement et/ou longitudinalement, et de manière interchangeable et/ou repositionnable, selon les besoins, avec possibilité à tous moments de modification de sa composition . The cells are arranged transversely and / or longitudinally, and in an interchangeable and / or repositionable manner, as required, with the possibility of modifying its composition at any time.
Un matelas selon l'invention est parfaitement autonome, il fonctionne sans compresseur, il bouge sur les propres sollicitations des utilisateurs . A mattress according to the invention is perfectly autonomous, it operates without a compressor, it moves on the user's own requests.
Du point de vue écologique il présente l'avantage de n'avoir pas ou peu d'empreinte carbone en fonctionnement. From an ecological point of view, it has the advantage of having little or no carbon footprint in operation.
Il est à noter qu'un tel matelas n'est pas d'usage strictement médical, il peut très bien être utilisé par des particuliers . D'autre part, il est parfaitement possible d'intégrer au dispositif de matelas une ou plusieurs cellules gonflables de type classique c'est-à-dire non équipée de système à décompression, et destinée à demeurer gonflée. It should be noted that such a mattress is not for strictly medical use, it can very well be used by individuals. On the other hand, it is perfectly possible to integrate into the mattress device one or more inflatable cells of conventional type, that is to say not equipped with a decompression system, and intended to remain inflated.
Les avantages et les caractéristiques du dispositif de matelas selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. The advantages and characteristics of the mattress device according to the invention will emerge more clearly from the description which follows and which relates to the appended drawing, which shows a non-limiting embodiment thereof.
Dans le dessin annexé : In the attached drawing:
- la figure 1 représente une vue schématique en perspective et :avec écorché, d'un dispositif de matelas selon l'invention, - Figure 1 shows a schematic perspective view and: with cutaway, of a mattress device according to the invention,
- la figure 2 représente une vue schématique en perspective d'une partie du même dispositif de matelas. - Figure 2 shows a schematic perspective view of part of the same mattress device.
En référence à la figure 1, on peut voir un dispositif de matelas 1 selon l'invention. Il comporte une housse extérieure amovible 2 représentée partiellement, à l'intérieur de laquelle sont disposées juxtaposées, des cellules gonflables 3. Referring to Figure 1, one can see a mattress device 1 according to the invention. It comprises a removable outer cover 2 shown partially, inside which are arranged juxtaposed, inflatable cells 3.
Chacune de ces cellules 3 comporte une enveloppe étanche 30, munie de deux valves unidirectionnelles à débit contrôlé, dont l'une 31 est adaptée à l'extraction de l'air tandis que l'autre 32 est adaptée à l'introduction de l'air. Each of these cells 3 comprises a sealed envelope 30, provided with two unidirectional controlled flow valves, one of which 31 is suitable for extracting air while the other 32 is suitable for the introduction of air. air.
D'autre part, chaque enveloppe 30 renferme un bloc 33 de mousse ou analogue, à mémoire de forme, susceptible d'une part de se déformer sous l'action d'un appui, et d'autre part de reprendre sa forme hors appui . On the other hand, each envelope 30 contains a block 33 of foam or the like, with shape memory, capable on the one hand of deforming under the action of a support, and on the other hand of resuming its shape without the support. .
On comprendra que lors de la déformation de la cellule 3 sous appui, l'air s'échappe par la valve 31, tandis que lors de la reprise de forme du bloc 33 cela provoque le gonflement de l'enveloppe 30 par aspiration au travers de la valve 32. It will be understood that during the deformation of the cell 3 under pressure, the air escapes through the valve 31, while during the reshaping of the block 33 this causes the envelope 30 to swell by suction through the valve 32.
Les cellules 3 peuvent être de formes différentes, comme on peut le voir, non limitativement, sur la figure 1 que ce soit dans le sens transversal et ou longitudinal, l'enveloppe 30 étant bien entendu de forme appropriée . The cells 3 can be of different shapes, as can be seen, without limitation, in FIG. 1, whether in the transverse and or longitudinal direction, the casing 30 being of course of suitable shape.
On peut ainsi voir une cellule 4 plus large, dans le sens de la longueur du matelas 1, que les autres cellules 3, ainsi qu'une cellule 5 dont la face supérieure 50 est d'une part bombée dans le sens de sa largeur, et creuse dans le sens transversal du matelas 1. We can thus see a cell 4 wider, in the direction of the length of the mattress 1, than the other cells 3, as well as a cell 5 whose upper face 50 is on the one hand convex in the direction of its width, and hollow in the transverse direction of the mattress 1.
Cela permet de construire un matelas sur mesure, en choisissant les cellules 3, en les ordonnant dans la housse, en fonction des besoins. This makes it possible to build a custom-made mattress, choosing 3 cells, ordering them in the cover, as needed.
D'autre part, comme les cellules 3 sont indépendantes, et non reliées à des moyens de gonflage et de gestion de pression, il est possible à tout moment d' échanger une ou plusieurs cellules 3, que ce soit pour un remplacement suite à une défection, ou pour modifier la géométrie du matelas. On the other hand, as the cells 3 are independent, and not connected to inflation and pressure management means, it is possible at any time to exchange one or more cells 3, whether for a replacement following a defection, or to modify the geometry of the mattress.
En référence à la figure 2, qui représente une cellule 3 en vue de dessous, on peut constater que l'enveloppe 30 est fermée au moyen d' une fermeture 34 de type zip étanche . With reference to FIG. 2, which represents a cell 3 seen from below, it can be seen that the casing 30 is closed by means of a closure 34 of the waterproof zip type.
