Abstract

The mattress (M) has a sheet connected to another sheet by soldering to form a set of anti-fall inflatable cells (C) which are defined by main transversal solders (4) and secondary connection solders (5) and are aligned along a central longitudinal axis (A) of the mattress, where the cells are individually inflatable. The solders are realized such that the cells present an upper carrier support (SP) at an inflated state. The carrier support forms a cup point that is transversally oriented with respect to the longitudinal axis of the mattress, so that the support is curved towards the exterior.

Description

Domaine techniqueTechnical area

La présente invention concerne le domaine technique des matelas gonflables anti-escarres qui sont utilisés en milieu hospitalier ou similaire pour l'alitement de personnes pendant des durées longues. L'invention a pour objet principal une nouvelle structure de matelas anti-escarres qui permet de réduire le risque de chute du lit pour le patient.The present invention relates to the technical field of inflatable anti-decubitus mattresses which are used in hospital or similar for bed resting people for long periods. The main object of the invention is a new structure of anti-decubitus mattress which makes it possible to reduce the risk of falling of the bed for the patient.

Art antérieurPrior art

Lorsqu'une personne est alitée pendant une durée longue sur un matelas traditionnel, les parties de son corps en contact prolongé avec le matelas subissent des compressions, qui à la longue finissent par provoquer la formation d'escarres. Cet inconvénient est particulièrement accentué lorsque le patient n'est pas en mesure de faire de l'exercice, même pendant une période courte. Le massage local n'est pas une mesure palliative efficace tant qualitativement qu'économiquement pour des patients destinés à être alités pendant une longue période.When a person is bedridden for a long time on a traditional mattress, the parts of his body in prolonged contact with the mattress undergo compressions, which eventually result in the formation of bedsores. This disadvantage is particularly accentuated when the patient is not able to exercise even for a short period. Local massage is not an effective palliative measure both qualitatively and economically for patients destined to be bedridden for a long time.

Dans le but de pallier ce problème de formation d'escarres, une solution connue à ce jour consiste à proposer des matelas gonflables anti-escarres, qui comportent une pluralité de cellules gonflables juxtaposées. Ce type de matelas est décrit par exemple dans le brevet américain US 5 704 084 . Les cellules du matelas anti-escarres sont gonflables individuellement au moyen d'un compresseur ou équivalent et selon une séquence et un cycle de gonflage prédéfinis en sorte de réduire les temps de compression des parties en contact avec les cellules du matelas.In order to overcome this problem of pressure ulcer formation, a known solution to date consists in providing inflatable anti-decubitus mattresses, which comprise a plurality of juxtaposed inflatable cells. This type of mattress is described for example in the US patent US 5,704,084 . The cells of the anti-decubitus mattress are individually inflatable by means of a compressor or equivalent and in a predefined sequence and inflation cycle so as to reduce the compression times of the parts in contact with the cells of the mattress.

En outre, un autre problème important rencontré lors de l'alitement de personne en milieu hospitalier ou équivalent est lié aux chutes accidentelles des personnes alitées. Ce problème est amplifié et dévient critique lorsque les personnes alitées ont des capacités motrices réduites, telles que par exemple des personnes venant de subir une intervention chirurgicale, des personnes totalement ou partiellement paralysées, ou des personnes âgées.In addition, another major problem encountered in the confinement of a person in a hospital setting or equivalent is related to accidental falls of bedridden persons. This problem is magnified and deviates critically when bedridden people have reduced motor skills, such as, for example, people who have just undergone surgery, people who are totally or partially paralyzed, or the elderly.

Pour remédier à ce problème, plusieurs solutions ont été envisagées. Par exemple, une première solution décrite dans la demande de brevet américain US 2006/0282955 consiste à enfiler transversalement, dans une structure comprenant deux coussins longitudinaux, une pluralité de cellules gonflables. Les deux coussins longitudinaux sont surélevés par rapport aux cellules gonflable en sorte d'améliorer le maintien latéral d'un patient allongé sur les cellules gonflables.To remedy this problem, several solutions have been envisaged. For example, a first solution described in the US patent application US 2006/0282955 consists in transversely slipping, in a structure comprising two longitudinal cushions, a plurality of inflatable cells. The two longitudinal cushions are raised relative to the inflatable cells so as to improve the lateral support of a patient lying on the inflatable cells.

Une deuxième solution décrite dans le brevet américain US 6 085 372 consiste à attacher deux coussins le long des bords longitudinaux d'un matelas constitué d'une pluralité de cellules gonflables disposées transversalement.A second solution described in the US patent US 6,085,372 consists of attaching two cushions along the longitudinal edges of a mattress consisting of a plurality of inflatable cells arranged transversely.

Une troisième solution décrite dans le brevet américain US 5 774 917 consiste à réaliser un matelas constitué d'une pluralité de cellules individuelles disposées transversalement au matelas. Chaque cellule individuelle est séparée, au moyen d'un diaphragme central, en deux cellules, une cellule droite et une cellule gauche. Chacune de ces cellules renferme un sac gonflé d'air et une membrane qui permettent de maintenir correctement le patient sur le matelas et éviter son glissement.A third solution described in the US patent US 5,774,917 consists in producing a mattress consisting of a plurality of individual cells arranged transversely to the mattress. Each individual cell is separated, by means of a central diaphragm, into two cells, a right cell and a left cell. Each of these cells contains an inflated bag of air and a membrane that can properly maintain the patient on the mattress and prevent slippage.

Une quatrième solution décrite dans la demande de brevet français FR 2 883 728 consiste à réaliser un matelas composé de cellules gonflables individuelles ayant la forme d'une cuvette et qui sont jointes les unes aux autres au moyen de boutons pression. Plus précisément, les cellules gonflables qui sont assemblées pour former le matelas anti-escarres ont leurs extrémités relevées par rapport à la surface de support qui est destinée à venir en contact avec le corps de la personne alitée.A fourth solution described in the French patent application FR 2,883,728 consists in producing a mattress composed of individual inflatable cells in the form of a bowl and which are joined to each other by means of snaps. More specifically, the inflatable cells which are assembled to form the anti-decubitus mattress have their ends raised with respect to the support surface which is intended to come into contact with the body of the bedridden person.

Ces structures de matelas anti-escarres permettent ainsi de prévenir le risque pour les patients de chutes accidentelles du matelas. Elles présentent cependant l'inconvénient d'être onéreuses car elles sont compliquées à mettre en oeuvre et/ou à fabriquer du fait de leur structure à cellules individuelles. Ces structures de matelas sont pour cette raison principalement destinées à un usage quotidien dans les hôpitaux.These anti-decubitus mattress structures help to prevent the risk of accidental falling of the mattress. However, they have the disadvantage of being expensive because they are complicated to implement and / or to manufacture because of their individual cell structure. These mattress structures are for this reason mainly intended for daily use in hospitals.

Une autre structure de matelas anti-escarres moins onéreuse et plus facile à mettre en oeuvre est par exemple décrite dans le brevet américain US 6 134 732 . Le matelas ainsi divulgué est constitué d'une feuille supérieure soudée sur une feuille inférieure, les soudures étant réalisées de manière à définir et délimiter une pluralité de cellules gonflables disposées transversalement au matelas. Egalement, en sorte de limiter les risque de chutes accidentelles des patients, une structure secondaire à cellules gonflables est positionnée sous le matelas sur lequel le patient est destiné à être alité. Cette structure comprend au moins deux cellules gonflables qui s'étendent longitudinalement par rapport au matelas et qui lorsqu'elles sont gonflées permettent de donner une forme incurvée au matelas de manière à envelopper sensiblement le patient. Bien que plus facile à mettre en oeuvre que les structures de matelas précédemment énoncées, cette solution n'est pas optimale du fait de la nécessité de recourir à une structure secondaire permettant de donner une forme incurvée au matelas sur lequel le patient est allongé.Another less expensive and easier to implement anti-decubitus mattress structure is for example described in US Pat. US 6,134,732 . The thus disclosed mattress consists of an upper sheet welded to a lower sheet, the welds being made to define and delimit a plurality of inflatable cells disposed transversely to the mattress. Also, in order to limit the risk of accidental falls of patients, a secondary structure inflatable cells is positioned under the mattress on which the patient is intended to be bedridden. This structure comprises at least two inflatable cells which extend longitudinally with respect to the mattress and which, when inflated, make it possible to give the mattress a curved shape so as to substantially envelop the patient. Although easier to implement than the above mattress structures, this solution is not optimal because of the need to use a secondary structure to give a curved shape to the mattress on which the patient is lying.

En outre, l'ensemble des matelas anti-escarres divulgués dans ces documents présentent un inconvénient secondaire qui est de ne pas pouvoir soulager les zones d'appui les plus sollicitées, et plus particulièrement les talons.In addition, the set of anti-decubitus mattresses disclosed in these documents have a secondary disadvantage that is not able to relieve the most stressed support zones, and more particularly the heels.

Un dernier inconvénient des structures de matelas anti-escarres précitées est lié au problème de la circulation sanguine du patient. En effet, le gonflement ou le dégonflement des cellules permet de prévenir la formation d'escarres, cependant, en position allongée, la circulation sanguine des patients alités n'est pas bonne en raison de leur immobilité. A ce jour, la seule manière d'améliorer la circulation sanguine de personnes alitées est de relever le dossier du lit et/ou la zone de pieds à l'aide de coussins et/ou de moyens mécaniques.A final disadvantage of the aforementioned anti-decubitus mattress structures is related to the problem of the patient's blood circulation. In fact, the swelling or deflation of the cells makes it possible to prevent the formation of bedsores, however, in an extended position, the blood circulation of the bedridden patients is not good because of their immobility. To date, the only way to improve the blood circulation of bedridden people is to raise the back of the bed and / or the foot area with cushions and / or mechanical means.

Objectif de l'inventionObjective of the invention

Description détailléedetailed description

On a représenté aux figures 1 à 3, un matelas gonflable anti-escarres M destiné à être utilisé en milieu hospitalier ou similaire pour l'alitement de personnes pendant des durées longues.Representatives Figures 1 to 3 , an inflatable anti-decubitus mattress M for use in a hospital or similar for bed resting people for long periods.

En référence aux figures 1 et 2, le matelas gonflable anti-escarres M s'étend le long d'un axe longitudinal central A et comprend une première feuille 1 et une deuxième feuille 2 en matériau thermo-soudable, par exemple en polyuréthane, qui sont liées par thermo-soudage sur toute leur périphérie selon une ligne de soudure périphérique 3 en sorte de former une enveloppe E hermétiquement fermée.With reference to Figures 1 and 2 the inflatable anti-decubitus mattress M extends along a central longitudinal axis A and comprises a first sheet 1 and a second sheet 2 of heat-sealable material, for example polyurethane, which are bonded by thermo-welding on their entire periphery along a peripheral weld line 3 so as to form a hermetically sealed envelope E.

Le matelas M comprend également une pluralité de soudures principales dites transversales 4 et de soudures secondaires dites de liaison 5 qui permettent de délimiter une multitude de cellules antichute C gonflables individuellement s'étendant le long de l'axe longitudinal central A et sensiblement perpendiculairement à cet axe A. Plus précisément, une cellule gonflable C est formée par deux soudures transversales 4 disposées en vis-à-vis l'une de l'autre et reliées entre elles par deux soudures de liaison 5 à proximité des bords longitudinaux du matelas M. Chaque cellule comprend en outre des moyens de gonflage et de dégonflage V de type valve qui permettent de gonfler ou dégonfler les cellules antichute C.The mattress M also comprises a plurality of so-called transversal main welds 4 and secondary bonding welds 5 which make it possible to define a multitude of individually inflatable fall arrest cells C extending along the central longitudinal axis A and substantially perpendicular thereto. A. More specifically, an inflatable cell C is formed by two transverse welds 4 arranged vis-à-vis one another and interconnected by two bonding welds 5 near the longitudinal edges of the mattress M. Each cell further comprises valve-type inflating and deflating means V to inflate or deflate the fall arrest cells C.

De manière connue en soi, lorsque le matelas M est utilisé, toutes les cellules gonflables individuelles C ne sont pas gonflées simultanément, mais sont gonflées et dégonflées individuellement, par l'intermédiaire des valves V, selon un cycle programmé, en sorte de modifier cycliquement les points de compression sur le corps de la personne allongée sur le matelas, ce qui permet de réduire les risques de formation d'escarres.In a manner known per se, when the mattress M is used, all the individual inflatable cells C are not inflated simultaneously, but are inflated and deflated individually, via the valves V, according to a programmed cycle, so as to modify cyclically the pressure points on the body of the person lying on the mattress, which reduces the risk of pressure ulcer formation.

Sur les figures 1 et 3, on a référencé SP la surface supérieure des cellules gonflables C. Cette surface supérieure SP s'étend entre deux soudures transversales 4 et deux soudures de liaison 5 délimitant une cellule gonflable C et forme la surface porteuse de ladite cellule C au contact de laquelle vient le corps de la personne alitée. Lorsque la cellule C est gonflée, cette surface porteuse SP forme avantageusement selon l'invention une cuvette qui est orientée transversalement à l'axe longitudinal central A du matelas M, d'où le nom de cellule antichute.On the Figures 1 and 3 , SP is referred to as the upper surface of the inflatable cells C. This upper surface SP extends between two transverse welds 4 and two bonding welds 5 delimiting an inflatable cell C and forms the bearing surface of said cell C in contact with which the body of the bedridden person. When the cell C is inflated, this carrier surface SP advantageously forms according to the invention a bowl which is oriented transversely to the central longitudinal axis A of the mattress M, hence the name of fall arrest cell.

Plus précisément, les soudures 4 et 5 sont réalisées de manière à ce que les cellules antichute C gonflables individuellement prennent, lorsqu'elles sont gonflées, la forme d'une cuvette orientée transversalement à l'axe longitudinal central A du matelas M. De cette manière, la surface porteuse SP des cellules gonflables C est courbée vers l'extérieur en sorte de faire obstacle au glissement latéral d'une personne allongée sur le matelas M, et de stabiliser latéralement cette personne en position centrale sur le matelas M. On réduit ainsi très sensiblement les risques de chutes accidentelles. Comme représenté à la figure 3, la surface porteuse SP présente une différence de hauteur D entre son point le plus haut, situé aux extrémités de la surface porteuse et son point le plus bas, situé au centre de la surface porteuse. Cette différence de hauteur D s'élève environ à 3 cm dans l'exemple particulier de réalisation des figures annexées. Néanmoins, le cas échéant et pour accentuer la forme de cuvette des cellules lorsqu'elles sont gonflées, on pourra modifier la réalisation des soudures 4 et 5 en sorte d'avoir une différence de hauteur D supérieure à 3 cm.More specifically, the welds 4 and 5 are made in such a way that the individually inflatable fall arrest cells C take, when they are inflated, the shape of a bowl oriented transversely to the central longitudinal axis A of the mattress M. In this way, the carrier surface SP of the inflatable cells C is bent outwards so as to prevent the lateral sliding of a person lying on the mattress M, and to laterally stabilize this person in a central position on the mattress M. thus very significantly the risk of accidental falls. As represented in figure 3 , the carrier surface SP has a difference in height D between its highest point, located at the ends of the bearing surface and its lowest point, located in the center of the bearing surface. This difference in height D is approximately 3 cm in the particular embodiment of the appended figures. Nevertheless, where appropriate and to accentuate the cell shape of the cells when they are inflated, the realization of the welds 4 and 5 can be modified so as to have a difference in height D greater than 3 cm.

Pour aboutir à la mise en oeuvre d'une cellule gonflable C ayant la forme d'une cuvette lorsqu'elle est gonflée, les soudures transversales 4 délimitant une cellule C doivent être réalisées de telle façon que la distance ou largeur I séparant les deux soudures transversales 4 à proximité de l'axe longitudinal central A doit être inférieure à la largeur L séparant lesdites soudures transversales 4 à proximité des soudures de liaison 5 (figure 1). De préférence, la distance ou largeur I est minimale au centre de la cellule C, sur l'axe longitudinal A, et est croissante du centre de ladite cellule antichute C, vers les extrémités de la cellule C jusqu'à atteindre la largeur maximale L. La distance séparant les deux soudures transversales 4 croit progressivement, par exemple et non exclusivement de manière rectiligne, incrémentale ou curviligne comme représenté dans les figures annexées. Les largeurs L et I séparant deux soudures transversales 4 d'une cellule C représentent la demi-circonférence du cylindre formé par ladite cellule, une fois celle-ci gonflée (figure 2). Ainsi, ladite cellule C gonflée a une hauteur h qui est minimale au niveau de l'axe longitudinal central A et une hauteur H qui est maximale au niveau de la jonction entre une soudure de liaison 5 et deux soudures transversales 4. De cette manière, plus la largeur d'une cellule C non gonflée est grande plus la hauteur de la cellule gonflée sera grande.To achieve the implementation of an inflatable cell C having the shape of a bowl when inflated, the transverse welds 4 delimiting a cell C must be made in such a way that the distance or width I separating the two welds transverse 4 near the central longitudinal axis A must be smaller than the width L separating said transverse welds 4 near the bonding welds 5 ( figure 1 ). Preferably, the distance or width I is minimal in the center of the cell C, on the longitudinal axis A, and is increasing from the center of said fall arrest cell C towards the ends of the cell C until reaching the maximum width L The distance separating the two transverse welds 4 increases progressively, for example and not exclusively rectilinearly, incrementally or curvilinearly as shown in the appended figures. The widths L and I separating two transverse welds 4 from a cell C represent the half-circumference of the cylinder formed by said cell, once inflated ( figure 2 ). Thus, said inflated cell C has a height h which is minimum at the central longitudinal axis A and a height H which is maximum at the junction between a bonding weld 5 and two transverse welds 4. In this way, the larger the width of an uninflated cell C, the larger the height of the inflated cell will be.

Par ailleurs, de préférence, le matelas gonflables anti-escarres M comprend trois secteurs de hauteurs différentes. Plus précisément, le matelas M comprend un premier secteur d'extrémité dit de tête Te, un secteur central dit de corps Co et un deuxième secteur d'extrémité dit de talons Ta, lesdits secteurs étant destinés respectivement à supporter la tête, le corps et les talons d'un patient alité sur le matelas M. De manière avantageuse, en sorte d'améliorer la circulation sanguine du patient et de soulager les zones d'appuis les plus fortes (talons), la hauteur h des cellules C est plus grandes au niveau des secteurs d'extrémités de tête Te et de talons Ta qu'au niveau du secteur central de corps Co. Idéalement, la hauteur h des cellules du secteur de talons Ta est plus grande que la hauteur h des cellules du secteur de tête Te. Pour arriver à ce type de structure de matelas gonflable anti-escarres, il suffit de modifier l'agencement des soudures 4 et 5 de manière à ce que la largeur I, séparant deux soudures transversales 4 des cellules C des secteurs de tête Te et de talons Ta soient supérieurs à la largeur I des cellules C du secteur de corps Co. Ce type de structure de matelas peut avantageusement être mise en oeuvre avec des cellules gonflables individuellement (avec ou sans effet antichute) ou des cellules gonflables individuelles.Moreover, preferably, the anti-decubitus inflatable mattress M comprises three sectors of different heights. More specifically, the mattress M comprises a first said end sector Te, a central sector called body Co and a second end sector called heel Ta, said sectors being intended respectively to support the head, the body and the heels of a patient lying on the mattress M. Advantageously, so as to improve the blood circulation of the patient and to relieve the strongest support zones (heels), the height h of the C cells is larger at the ends of the head ends Te and heels Ta at the central area of the body Co. Ideally, the height h of the cells of the heel sector Ta is greater than the height h of the cells of the leading sector You. To arrive at this type of anti-decubitus inflatable mattress structure, it suffices to modify the arrangement of the welds 4 and 5 so that the width I, separating two transverse welds 4 from the C cells of the head sectors Te and heels Ta are greater than the width I of the C cells of the body sector C. This type of mattress structure can advantageously be implemented with individually inflatable cells (with or without a fall arrest effect) or individual inflatable cells.

L'invention n'est toutefois pas limitée à la variante de réalisation de matelas gonflable anti-escarres qui a été décrite en référence aux figures annexées, mais s'étend plus généralement à toute réalisation couverte par les revendications annexées.The invention is however not limited to the embodiment of inflatable mattress anti-decubitus which has been described with reference to the accompanying figures, but extends more generally to any embodiment covered by the appended claims.

Par exemple, dans la variante particulière des figures annexées, les cellules gonflables individuelles C sont juxtaposées selon l'axe A du matelas M et perpendiculairement à cet axe longitudinal A. De cette manière, deux soudures transversales 4 de deux cellules gonflables C consécutives délimitent une zone Z1 vide et non gonflable. Toujours dans la variante particulière des figures annexées, cette zone Z1 a une forme sensiblement oblongue ou ovale, néanmoins, cette forme particulière n'est pas exclusive, ou pourrait également imaginer une zone Z1 ayant par exemple la forme d'un losange (cas où la largeur I séparant deux soudures transversales 4 croît de manière rectiligne). De même, pour que les cellules gonflables C prennent la forme d'une cuvette une fois gonflée, elles ne doivent pas nécessairement être juxtaposées le long du matelas M. On pourrait, en effet, également les disposer le long du matelas M de manière à ce qu'elles soient entièrement indépendantes et espacées les unes des autres (voir figure 4). Enfin, on pourrait également imaginer un matelas gonflables anti-escarres dans lequel on aurait seulement les soudures transversales 4 et de liaison 5 car il n'est pas nécessaire que les feuilles 1 et 2 soient liées par thermo-soudage sur toute leur périphérie le long de la ligne de soudure périphérique 3 pour que les cellules C prennent la forme d'une cuvette lorsqu'elles sont gonflées.For example, in the particular variant of the appended figures, the Individual inflatable cells C are juxtaposed along the axis A of the mattress M and perpendicular to this longitudinal axis A. In this way, two transverse welds 4 of two consecutive inflatable cells C delimit a zone Z 1 empty and non-inflatable. Still in the particular variant of the appended figures, this zone Z 1 has a substantially oblong or oval shape, however, this particular shape is not exclusive, or could also imagine a zone Z 1 having for example the shape of a rhombus ( case where the width I separating two transverse welds 4 increases in a rectilinear manner). Similarly, so that the inflatable cells C take the shape of a bowl when inflated, they do not necessarily have to be juxtaposed along the mattress M. They could, indeed, also be arranged along the mattress M so as to they are completely independent and spaced apart (see figure 4 ). Finally, one could also imagine an inflatable anti-decubitus mattress in which we would have only the transverse welds 4 and connecting 5 because it is not necessary that the sheets 1 and 2 are bonded by thermo-welding on their entire periphery along of the peripheral sealing line 3 so that the cells C take the shape of a bowl when they are inflated.
