Abstract
Description
La présente invention a pour objet un dispositif de matelas basse pression réglable, utilisé notamment pour empêcher la formation d'escarres.The subject of the present invention is a mattress device adjustable low pressure, used in particular to prevent pressure ulcer formation.
Une escarre consiste en une nécrose de la peau résultant d'un défaut d'irrigation sanguine, il se développe souvent chez les personnes obligées de rester longtemps alitées, car la pression qu'exerce le poids du corps peut engendrer, en des points particuliers, une interruption de la circulation sanguine.A pressure ulcer consists of a necrosis of the skin resulting from a lack of blood supply, it often develops in people who have to stay in bed for a long time because the pressure that the weight of the body exerts can generate, at points individuals, an interruption in blood circulation.
On connaít déjà des matelas permettant d'améliorer le confort du
patient en certains points du matelas. C'est le cas du matelas
proposé dans le document EP 0 046 008, lequel comporte une
cavité dans laquelle est placé un insert qui comprend une base
gonflable dont la face supérieure présente des reliefs adaptés à
soutenir un corps humain, et qui est recouverte d'une couverture
définissant avec elle un espace dans lequel est insufflé un gaz
sous pression en sorte que, même si ladite couverture est
perforée pour permettre l'échappement dudit gaz par le haut, la
pression de celui-ci demeure légèrement supérieure à celle de la
base gonflable.We already know mattresses to improve the comfort of
patient at certain points on the mattress. This is the case with the mattress
proposed in
Si le matelas objet de ce document accroít le confort du patient, il ne permet pas toutefois d'empêcher la formation d'escarres puisqu'il est statique.If the mattress covered by this document increases the comfort of the patient, it does not prevent the formation since it is static.
C'est également le cas du dispositif de matelas objet du document WO 00 18275, lequel consiste en un système de matelas à modules multiples, permettant, dans un lit à deux places, à chacun des utilisateurs de personnaliser son côté de lit, et d'augmenter la longévité du lit, du fait de l'interchangeabilité des éléments composant celui-ci, lesquels éléments peuvent être des éléments tubulaires gonflés à une pression donnée. This is also the case for the mattress device which is the subject of the WO 00 18275, which consists of a mattress system with multiple modules, allowing, in a double bed, to each user to customize their bed side, and increase the longevity of the bed, due to interchangeability elements composing this one, which elements can be tubular elements inflated to a given pressure.
Pour pallier l'inconvénient des matelas du type de ceux précités, on a proposé des dispositifs de matelas ou analogue qui présentent des qualités dynamiques permettant réellement d'éviter que les personnes alitées ne développent des escarres. Ce résultat est obtenu par la création d'un mouvement à la surface du matelas au moyen d'une circulation d'un fluide, ce qui engendre en quelque sorte un massage du patient.To overcome the disadvantage of mattresses of the type of those mentioned above, mattress devices or the like have been proposed which have dynamic qualities that actually allow to prevent bedridden people from developing bedsores. This is achieved by creating a movement at the surface of the mattress by means of a circulation of a fluid, this which somehow generates a massage for the patient.
Il existe différents types de ces dispositifs de matelas, les plus efficaces sont ceux comportant des cellules gonflables s'étendant transversalement, réparties longitudinalement, et que l'on peut, par l'intermédiaire d'un moyen de gonflage, gonfler alternativement ou simultanément, à une pression variable, de manière à créer en surface du matelas un mouvement tel qu'une vague par exemple.There are different types of these mattress devices, the more effective are those with inflatable cells extending transversely, distributed longitudinally, and that it is possible, by means of an inflation means, to inflate alternately or simultaneously, at a variable pressure, so as to create a movement on the surface of the mattress such as vague for example.
Le gonflement des cellules peut être réalisé avec de l'eau, mais on utilise de préférence de l'air, dont le transport est plus facilement maítrisable et qui présente des temps de réaction plus courts.Cell swelling can be done with water, but preferably, air is used, the transport of which is more easily controllable and has reaction times shorter.
De manière générale, un tel matelas consiste en une succession de cellules gonflables soudées entre-elles ou maintenues par une enveloppe, l'ensemble étant recouvert d'une housse en matière textile souple.Generally, such a mattress consists of a succession inflatable cells welded together or held by a envelope, the whole being covered with a material cover flexible textile.
Pour certains de ces dispositifs, toutes les cellules communiquent entre-elles, elles peuvent même consister en un boudin gonflable agencé en un serpentin. De tels dispositifs sont d'un usage et d'une efficacité limités, puisqu'ils ne permettent pas de faire varier la pression de manière différente en des points différents.For some of these devices, all cells communicate with each other, they can even consist of a inflatable tube arranged in a serpentine. Such devices are of limited use and effectiveness, since they do not not allow you to vary the pressure differently at different points.
Sur d'autres dispositifs de matelas, il est proposé de séparer les cellules en plusieurs zones, pour pouvoir les alimenter de manière indépendante, et ainsi offrir des mouvements plus variés.On other mattress devices, it is proposed to separate the cells in several zones, in order to be able to supply them with independently, and thus offer more movements varied.
On connaít également des dispositifs de matelas du type de celui
décrit dans le document EP 0 445 539, et qui consiste en un
matelas à l'usage de patients souffrant d'escarres et/ou
d'incontinence, comportant sur au moins une face, au moins une
région où la consistance du matelas peut être modifiée. A cet
effet, le matelas comporte au moins une cavité apte à recevoir
un insert, lequel peut être constitué d'une multiplicité de
chambres gonflables individuellement et à volonté au moyen d'un
fluide.We also know mattress devices of the type of that
described in
Ce dispositif de matelas, comme la plupart, présente des inconvénients, particulièrement en matière d'entretien. En effet, les cellules sont directement exposées aux salissures et souillures, puisque uniquement protégées par la housse. Or, malgré le fait que ces cellules soient généralement conçues pour pouvoir être lavées, voire stérilisées, cela demeure une opération peu aisée, et contraignante.This mattress device, like most, has disadvantages, particularly in terms of maintenance. In effect, the cells are directly exposed to dirt and soiling, since only protected by the cover. Gold, despite the fact that these cells are generally designed to being able to be washed or even sterilized, this remains a operation not very easy, and restrictive.
En outre, les dispositifs de matelas connus sont généralement adaptés à une personne de taille moyenne, ce qui présente des inconvénients pour les personnes de grande ou petite taille.In addition, known mattress devices are generally suitable for a medium-sized person, which presents disadvantages for tall and short people.
Par ailleurs, les patients ne demeurent pas toujours alités, ils peuvent également prendre une position semi-allongée, sur un fauteuil par exemple, laquelle peut également favoriser le développement d'escarres. On connaít toutefois des fauteuils recouverts d'un dispositif de matelas basse pression réglable, dont le fonctionnement est analogue à ceux utilisés sur un lit, il est cependant difficile, pour des raisons évidentes de coût, de mettre à la disposition d'une seule personne un lit et un fauteuil chacun équipé d'un dispositif de matelas tel que décrit précédemment. In addition, patients do not always stay in bed, they can also take a semi-recumbent position, on a chair for example, which can also promote development of bedsores. However, we know armchairs covered with an adjustable low pressure mattress device, whose functioning is analogous to those used on a bed, however, it is difficult, for obvious cost reasons, to provide a single bed and a chair each equipped with a mattress device as described previously.
La présente invention a pour but de proposer un dispositif de matelas basse pression réglable, utilisé notamment pour empêcher la formation d'escarres, permettant de remédier aux divers inconvénients précités.The object of the present invention is to propose a device for adjustable low pressure mattress, used in particular to prevent the formation of pressure sores, making it possible to remedy the various aforementioned drawbacks.
Le dispositif de matelas basse pression réglable, utilisé notamment pour empêcher la formation d'escarres, objet de la présente invention, est du type comportant plusieurs cellules gonflables alternativement, simultanément ou à pression variable, et il se caractérise essentiellement en ce que lesdites cellules sont incorporées, individuellement et/ou groupées, dans au moins un insert destiné à être placé, de façon amovible, dans au moins une excavation pratiquée dans une face du matelas.The adjustable low pressure mattress device used in particular to prevent the formation of pressure sores, the subject of the present invention is of the type comprising several cells inflatable alternately, simultaneously or by pressure variable, and it is essentially characterized in that said cells are incorporated, individually and / or grouped, in at least one insert intended to be placed, so removable, in at least one excavation made in one face of the mattress.
Le dispositif de matelas selon l'invention peut comporter soit plusieurs inserts incorporant une ou plusieurs cellules gonflables et prenant place dans des excavations pratiquées dans le matelas à des emplacements spécifiques, soit un seul insert incorporant plusieurs cellules gonflables réparties en groupes de manière à correspondre à des emplacements spécifiques.The mattress device according to the invention can comprise either several inserts incorporating one or more cells inflatable and taking place in excavations made in the mattress in specific locations, i.e. a single insert incorporating several inflatable cells divided into groups so as to correspond to specific locations.
Selon une caractéristique additionnelle du dispositif selon l'invention, le matelas consiste en un bloc de mousse synthétique recouvert d'une housse de protection amovible.According to an additional characteristic of the device according to the invention, the mattress consists of a block of foam synthetic covered with a removable protective cover.
Selon une autre caractéristique additionnelle du dispositif selon l'invention, chaque insert consiste en un bloc de mousse synthétique susceptible d'être recouvert d'une housse de protection amovible, et dans lequel est pratiqué au moins un logement destiné à accueillir au moins une cellule gonflable.According to another additional characteristic of the device according to the invention, each insert consists of a block of foam synthetic material which can be covered with a cover removable protection, and in which at least one housing intended to accommodate at least one inflatable cell.
Selon une autre caractéristique additionnelle du dispositif selon l'invention, le matelas et l'insert sont réalisés par superposition de deux couches de mousses synthétiques de caractéristiques différentes en sorte que la couche supérieure soit agréable au contact.According to another additional characteristic of the device according to the invention, the mattress and the insert are produced by superposition of two layers of synthetic foam different characteristics so that the top layer be pleasant to the touch.
Selon un premier mode de réalisation du dispositif selon l'invention, il comporte plusieurs inserts dont au moins deux, de dimensions égales et où les cellules gonflables sont disposées différemment, sont interchangeables.According to a first embodiment of the device according to the invention, it comprises several inserts, at least two of which, of equal dimensions and where the inflatable cells are arranged differently, are interchangeable.
Deux inserts du dispositif de matelas selon l'invention, les deux inserts extrêmes par exemple, peuvent ainsi présenter les mêmes caractéristiques dimensionnelles, par contre les cellules gonflables peuvent y être réparties différemment, en sorte qu'un échange de positions peut permettre de modifier les emplacements spécifiques à traiter. Cela permet avantageusement d'adapter le dispositif de matelas selon l'invention à la taille du patient.Two inserts of the mattress device according to the invention, the two extreme inserts for example, can thus present the same dimensional characteristics, however cells inflatables can be distributed differently, so that a swapping positions can change locations specific to be treated. This advantageously makes it possible to adapt the mattress device according to the invention for the size of the patient.
De manière avantageuse, au moins l'un des inserts du premier mode de réalisation est relié au compresseur d'air indépendamment des autres inserts, en sorte qu'il puisse être utilisé comme coussin.Advantageously, at least one of the inserts of the first embodiment is connected to the air compressor independently of the other inserts, so that it can be used as a cushion.
Selon un second mode de réalisation du dispositif selon l'invention, il comporte un insert qui incorpore au moins deux groupes de cellules gonflables, et qui est réversible dans le sens de la longueur.According to a second embodiment of the device according to the invention, it comprises an insert which incorporates at least two groups of inflatable cells, and that is reversible in the sense of length.
Selon une caractéristique additionnelle du second mode de réalisation du dispositif selon l'invention, l'insert comporte deux groupes inégaux en nombre de cellules gonflables, le groupe le plus grand en nombre de cellules gonflables est destiné à prendre place sous le bassin du patient, tandis que le groupe le plus petit en nombre de cellules gonflables est destiné à prendre place sous les pieds ou sous la tête dudit patient, selon l'orientation donnée audit insert. According to an additional characteristic of the second mode of embodiment of the device according to the invention, the insert comprises two groups unequal in number of inflatable cells, the group the largest number of inflatable cells is intended for take place under the patient's pelvis, while the group smaller number of inflatable cells is intended for take place under the feet or under the head of said patient, according to the orientation given to said insert.
Selon une autre caractéristique additionnelle du dispositif selon l'invention, l'épaisseur de l'insert va en décroissant à partir de la fin du groupe le plus important en nombre de cellules gonflables jusqu'à son extrémité comportant l'autre groupe de cellules gonflables.According to another additional characteristic of the device according to the invention, the thickness of the insert decreases to from the end of the largest group in number of inflatable cells up to its end with the other group of inflatable cells.
De manière avantageuse, l'insert du second mode de réalisation du dispositif selon l'invention, est muni, du côté du groupe de plus petit nombre de cellules gonflables, de moyens de fixation au dossier d'un fauteuil.Advantageously, the insert of the second embodiment of the device according to the invention, is provided, on the side of the group of smaller number of inflatable cells, means of attachment in the back of an armchair.

En référence aux figures 1 et 2, on peut voir que selon un
premier mode de réalisation, un dispositif de matelas basse
pression réglable, utilisé notamment pour empêcher la formation
d'escarres, selon l'invention se présente sous la forme d'un
bloc 1 d'un matériau souple mais relativement ferme tel qu'une
mousse de matière synthétique, dans lequel sont pratiquées des
excavations 10, 11 et 12 où logent des inserts, respectivement
13, 14 et 15, qui incorporent chacun des cellules gonflables 16
de forme allongée et disposées parallèlement les unes à côté des
autres, et qui sont reliées, de manière indépendante ou non, à
un compresseur d'air, non représenté.With reference to FIGS. 1 and 2, it can be seen that according to a
first embodiment, a low mattress device
adjustable pressure, used in particular to prevent formation
pressure ulcers according to the invention is in the form of a
On notera que le dispositif de matelas selon l'invention est, en utilisation, recouvert d'une housse amovible, non représentée.It will be noted that the mattress device according to the invention is, in use, covered with a removable cover, not shown.
Il y a lieu également de noter que, dans une variante de
réalisation non représentée, le bloc 1 peut consister en un
matelas gonflable qui, après gonflage, laisse subsister une ou
plusieurs lumières aptes à recevoir les inserts. Un tel matelas
présente des avantages du point de vue nettoyage et stockage.It should also be noted that, in a variant of
embodiment not shown,
Comme on peut le voir sur la figure 2, les excavations 10, 11 et
12 sont réalisées dans la face inférieure du bloc 1, en sorte
que les inserts 13, 14 et 15 y sont introduits par en dessous,
et également que le bloc 1 est constitué de deux couches 17 et
18 de matériaux différents, en l'occurrence des mousses
synthétiques qui peuvent être solidarisées par collage. La
couche supérieure 17 est de faible épaisseur par rapport à la
couche inférieure 18, ces couches peuvent être toutes les deux
réalisées dans le même matériau tel qu'une mousse polyuréthanne
base poly éther, avec une différence de traitement pour la
couche supérieure 17, en sorte que celle-ci soit agréable au
contact, même au travers de la housse de protection.As can be seen in Figure 2,
On notera que dans le mode de réalisation représenté, les
excavations 10, 11 et 12 sont pratiquées dans la totalité de
l'épaisseur de couche inférieure 18 en sorte que les inserts 13,
14 et 15 viennent directement au contact de la couche supérieure
17 il est toutefois possible qu'il subsiste une partie de la
couche inférieure 18 entre les inserts 13, 14 et 15 et la couche
supérieure 17.Note that in the embodiment shown, the
Les inserts 13, 14 et 15 consistent en des blocs faits dans un
matériau de préférence identique à celui dont est fait le bloc
1, et dans lesquels sont réalisés des logements pour les
cellules 16 qui consistent en des enveloppes étanches, telles
que des tubes ou gaines, qui peuvent être identiques à celles
utilisées sur les dispositifs actuels.Inserts 13, 14 and 15 consist of blocks made in a
material preferably identical to that of which the block is made
1, and in which are housed for
Par le gonflement et/ou le dégonflement des cellules 16 en
alternance ou simultanément selon des séquences prédéfinies, on
crée à la surface du matelas un mouvement assimilable par le
patient à un massage. Le gonflement et le dégonflement des
cellules 16 est assuré par le compresseur d'air, qui lui-même
est commandé par un processeur qui peut éventuellement être
programmé pour tenir compte de l'état et/ou du poids du patient.By the swelling and / or deflation of the
Avantageusement, le dispositif de matelas selon l'invention est
d'un entretien aisé, puisque les inserts 13, 14 et 15 sont
protégés dans le bloc 1. Par ailleurs, il est également possible
que chacun des inserts 13, 14 et 15 soit enveloppé dans une
housse de protection.Advantageously, the mattress device according to the invention is
easy maintenance, since the
En référence maintenant à la figure 3, on peut voir que, selon
une variante du premier mode de réalisation du dispositif de
matelas selon l'invention, ce dernier comporte un bloc 2
constitué du rapprochement par collage de deux couches 27 et 28
en mousse de matière synthétique, et dans lequel sont pratiquées
trois excavations 20, 21 et 22 destinées à loger des inserts
respectivement 23, 24 et 25 qui incorporent chacun des cellules
gonflables 26, les excavations 20, 21 et 22 étant réalisées dans
la face supérieure du bloc 2, les inserts 23, 24 et 25 y étant
donc introduits par le dessus.Referring now to Figure 3, we can see that, according to
a variant of the first embodiment of the
mattress according to the invention, the latter comprises a block 2
consisting of the joining by bonding of two
Les inserts 23, 24 et 25, qui de préférence sont enveloppés
chacun dans une housse de protection non représentée, sont
constitués d'un bloc de matière identique à celle de la couche
inférieure 28, recouvert d'une couche de matière identique à
celle de la couche supérieure 27, de manière à réaliser une
continuité lorsque les inserts 23, 24 et 25 sont logés dans les
excavations respectivement 20, 21 et 22.
Bien entendu, dans cette variante, l'ensemble du bloc 2 est également enveloppé dans une housse de protection.Of course, in this variant, the whole of block 2 is also wrapped in a protective cover.
On notera que l'un au moins des inserts 23, 24 et 25, peut être
désolidarisé de l'ensemble pour pouvoir être relié de manière
autonome au compresseur, et servir de coussin sur une chaise ou
analogue.It will be noted that at least one of the
En référence maintenant à la figure 4, on peut voir le même bloc
2 pour lequel les inserts extrêmes 23 et 25 ont été intervertis,
c'est à dire qu'ils ont été placés dans les excavations
respectivement 22 et 20. Referring now to Figure 4, we can see the same block
2 for which the
Or, les cellules 26 des inserts 23 et 25 ne sont pas
régulièrement réparties, elles sont groupées d'un côté, et pas
du même selon l'insert considéré. Aussi, l'inversion des inserts
23 et 25 permet de modifier les caractéristiques dimensionnelles
de la partie active du dispositif de matelas, qui est la plus
petite sur la figure 3 et la plus grande sur la figure 4.However, the
Il serait possible d'obtenir le même résultat en retournant les
inserts 23 et 25, toutefois, il se poserait le problème du
passage des alimentations en air, non représentées, qui sont
connectées à ceux-ci latéralement.It would be possible to obtain the same result by returning the
En référence maintenant aux figures 5 et 7, on peut voir selon
un second mode de réalisation, qu'un dispositif de matelas selon
l'invention comporte un bloc 3 dans la face supérieure duquel
est pratiquée une excavation 30 où est logé un insert 31, le
bloc 3 et l'insert 31 étant également constitués de la
superposition de deux couches de matériaux différents, en
l'occurrence une couche supérieure 32 et une couche inférieure
33, toutes deux d'une mousse polyuréthanne base poly éther,
celle de la couche supérieure 32 étant traitée pour être
agréable au contact, même au travers d'une housse de protection.Referring now to Figures 5 and 7, we can see according to
a second embodiment, that a mattress device according to
the invention comprises a
L'insert 31 renferme des cellules gonflables 34 réparties en
deux groupes 35 et 36 d'un nombre différent de cellules
gonflables 34. Ainsi, dans ce mode de réalisation, le groupe 35
est constitué de six cellules gonflables 34 tandis que le groupe
36 est constitué de trois cellules gonflables 34.The
Par ailleurs, l'excavation 30 représente en longueur environ les
deux tiers du bloc 3, et est décalée d'un côté, en sorte que
lorsque l'insert 31 y est introduit, le groupe 35 occupe
sensiblement la région centrale du bloc, celle destinée à
soutenir le bassin du patient. Aussi, selon l'orientation du
bloc 3 sur le lit, le groupe 36 de cellules gonflables 34 est
destiné à soutenir la tête ou les pieds du patient. Furthermore, the
On notera que l'insert 31 peut être introduit dans l'excavation
30 sous la housse de protection du bloc 3 ou par-dessus celle-ci.Note that the
En référence à la figure 6, on peut voir selon une variante que
l'épaisseur de l'insert 31 va en décroissant progressivement à
partir de la dernière cellule gonflable 34 du groupe 35, jusqu'à
l'extrémité de l'insert 31 du côté de du groupe 36. Cette
caractéristique permet d'obtenir, lorsque le groupe 36 est
destiné à soutenir les pieds du patient, une décharge
progressive physio-anatomique des membres inférieurs du patient,
allant du creux poplité aux parties rétro-achiléennes.Referring to Figure 6, we can see according to a variant that
the thickness of the
En référence maintenant à la figure 8, on peut voir que l'insert
31 peut être utilisé comme matelas pour un fauteuil, non
représenté, dans ce cas il est divisé en deux parties, une
partie 37 qui incorpore le groupe 35 de cellules 34 et qui
constitue l'assise, et une partie 38 qui incorpore le groupe 36
de cellules 34 qui sert d'appui à la tête du patient et la zone
dépourvue de cellules contre laquelle prend appui le dos. On
notera que la partie 38 comporte des moyens 39 de fixation au
fauteuil, tels que des sangles.Referring now to Figure 8, we can see that the
Dans cette configuration, la variation d'épaisseur de l'insert
31, en l'occurrence de sa partie 38, permet de décharger
progressivement le tronc du patient, des lombaires jusqu'aux
omoplates.In this configuration, the variation in thickness of the
Dans une variante, non représentée, les différents inserts consistent chacun en une bande de tissu ou analogue, éventuellement imperméabilisé, sur une face de laquelle sont solidarisées transversalement des enveloppes longitudinales destinées chacune à recevoir une cellule gonflable. Après enlèvement des cellules, la bande de tissu ou analogue peut être lavée aisément et être pliée et rangée. In a variant, not shown, the different inserts each consist of a strip of fabric or the like, possibly waterproofed, on one side of which are joined transversely to the longitudinal envelopes each intended to receive an inflatable cell. After removal of cells, tissue band or the like may be easily washed and folded and stored.
Cette variante de réalisation est particulièrement adaptée à être associée à un matelas gonflable, l'ensemble consistant alors en un entourage gonflable, un boudin périphérique par exemple, au centre duquel est disposée la bande de tissu munie de ses enveloppes transversales renfermant les cellules gonflables, lesquelles sont bien entendu de même épaisseur que l'entourage.This variant is particularly suitable for be associated with an inflatable mattress, the set consisting then in an inflatable surrounding, a peripheral tube by example, in the center of which is placed the strip of fabric provided of its transverse envelopes containing the cells inflatable, which are of course the same thickness as the entourage.
Le dispositif de matelas selon l'invention, offre de nombreux avantages par rapport aux dispositifs existants. Outre les facilités de nettoyage aussi bien du matelas que des éléments actifs que constituent les cellules gonflables, la modularité et la réversibilité des éléments qui le composent donnent au dispositif selon l'invention une grande polyvalence d'utilisation.The mattress device according to the invention offers numerous advantages over existing devices. Besides the easy cleaning of both the mattress and the elements inflatable cells, modularity and the reversibility of the elements that compose it give the device according to the invention great versatility of use.
