Abstract
Description
La présente invention a pour objet un dispositif anti-talonnement d'un support souple tel qu'un coussin, matelas ou analogue, et plus particulièrement un dispositif permettant d'anticiper un risque de talonnement.The subject of the present invention is an anti-heeling device of a flexible support such as a cushion, mattress or the like, and more particularly a device making it possible to anticipate a risk of being tied up.
Un tel dispositif est notamment destiné à équiper les supports souples, en mousse ou gonflables destinés à recevoir le corps de patients, tels que par exemple un coussin ou un matelas pour la prévention et le traitement des escarres, utilisé et conçu en vue d'empêcher les risques de talonnement, c'est-à-dire les risques de contact du corps dudit patient avec la partie la plus dure du support ou la base sur laquelle repose ledit support.Such a device is particularly intended to equip the flexible supports, foam or inflatable for receiving the body of patients, such as for example a cushion or a mattress for the prevention and treatment of bedsores, used and designed to prevent the risk of bottleneck, that is to say the risk of contact of the body of said patient with the hardest part of the support or the base on which said support.
On sait que les personnes contraintes pour des raisons médicales ou physiques de rester une longue période dans une certaine position, assise ou alitée par exemple, sont susceptibles de développer des nécroses de la peau en des points particuliers du corps au niveau desquels le corps prend appui et où la circulation sanguine est réduite voire interrompue.It is known that persons who are forced for medical or physical reasons to stay for a long time in a certain position, sitting or bedridden for example, are likely to develop necrosis of the skin at particular points in the body at which the body is supported. and where the blood circulation is reduced or interrupted.
Pour pallier ces inconvénients on sait qu'il faut élargir la surface de contact du corps du patient avec le support ce qui peut être obtenu avec notamment des supports gonflables, tels que des matelas ou analogues, présentant une pression de gonflage adéquate.To overcome these drawbacks it is known that it is necessary to enlarge the contact surface of the body of the patient with the support which can be obtained with particular inflatable supports, such as mattresses or the like, having an adequate inflation pressure.
Pour des supports gonflables, du fait de la morphologie différente des patients ainsi que de l'inégalité de la répartition de leur masse, il est nécessaire d'approprier la pression de gonflage selon les caractéristiques de l'utilisateur, en sorte d'une part, que la pression ne soit pas trop élevée pour atteindre une surface de contact, entre le corps et le support, la plus grande possible, et d'autre part que l'enfoncement ne dépasse pas un certain seuil au-delà duquel il y a risque de talonnement, c'est-à-dire risque de création d'une zone de contact avec la structure portant le support gonflable.For inflatable supports, because of the different morphology of the patients as well as the inequality of the distribution of their mass, it is necessary to appropriate the inflation pressure according to the characteristics of the user, so on the one hand that the pressure is not too high to reach a contact area, between the body and the support, the greatest possible, and secondly that the depression does not exceed a certain threshold beyond which there is a risk of bottleneck, that is to say risk of creating a contact zone with the structure carrying the inflatable support.
Pour remédier à cet inconvénient, il est connu d'adapter la pression et de vérifier le niveau d'enfoncement en glissant une main entre le support gonflable et le corps, technique qui demeure aléatoire et évidemment dérangeante pour le patient.To overcome this disadvantage, it is known to adapt the pressure and check the level of depression by sliding a hand between the inflatable support and the body, a technique that remains random and obviously disturbing for the patient.
Pour tenter de pallier cet inconvénient il a été proposé d'équiper les supports gonflables de manomètres permettant de faire correspondre la pression de gonflage à la morphologie de l'utilisateur et plus exactement au poids et à la taille de celui-ci en utilisant des tableaux ou analogues établissant des correspondances.In an attempt to overcome this drawback, it has been proposed to equip the inflatable supports with manometers making it possible to match the inflation pressure to the morphology of the user and more exactly to the weight and the size of the latter by using tables. or analogous connecting.
Cependant, la masse corporelle est répartie différemment. Ainsi pour un même poids et une même taille, la pression de gonflage optimale peut être différente.However, body mass is distributed differently. Thus for the same weight and the same size, the optimal inflation pressure may be different.
De plus, ce n'est pas en augmentant la pression de gonflage qu'il est possible de prévenir un risque de talonnement.In addition, it is not by increasing the inflation pressure that it is possible to prevent a risk of tailgating.
La présente invention a pour but de remédier aux divers inconvénients précités en proposant un dispositif anti-talonnement d'un support souple tel qu'un coussin, matelas ou analogue, et plus particulièrement un dispositif, permettant d'anticiper un risque de talonnement d'une très grande fiabilité tout en étant de conception simple et d'utilisation aisée et, pour les supports gonflables, s'affranchissant du contrôle de la pression de gonflage.The object of the present invention is to remedy the various aforementioned drawbacks by proposing an anti-heeling device of a flexible support such as a cushion, mattress or the like, and more particularly a device, making it possible to anticipate a risk of tailwindness. a very high reliability while being simple design and easy to use and, for inflatable media, free from the control of the inflation pressure.
Selon l'invention, le dispositif anti-talonnement d'un support souple tel qu'un coussin, matelas ou analogue, comprenant un côté supérieur et un côté inférieur, se caractérise essentiellement en ce qu'il comporte, intérieurement, au moins un moyen prévu apte à permettre l'évaluation de la distance qui sépare lesdits côtés supérieur et inférieur, associé à un moyen apte à délivrer un signal lorsque ladite distance atteint une valeur seuil.According to the invention, the anti-heeling device of a flexible support such as a cushion, mattress or the like, comprising an upper side and a lower side, is essentially characterized in that it comprises, internally, at least provided means adapted to allow the evaluation of the distance separating said upper and lower sides, associated with means capable of delivering a signal when said distance reaches a threshold value.
Le support souple est destiné à être placé, par son côté inférieur, sur une structure rigide ou non, un sommier ou analogue par exemple, et à recevoir, sur son côté supérieur, un objet ou un corps à supporter. Dans le cas d'un enfoncement du support souple, en un point comme en plusieurs, selon une profondeur prédéterminée, il y a émission d'un signal permettant d'informer qu'il est nécessaire de rectifier la pression de gonflage.The flexible support is intended to be placed, by its lower side, on a rigid structure or not, a bed base or the like for example, and to receive, on its upper side, an object or a body to support. In the case of a depression of the flexible support, at a point as in several, according to a predetermined depth, there is emission of a signal to inform that it is necessary to rectify the inflation pressure.
La profondeur prédéterminée correspond au seuil limite de talonnement. Elle peut aussi correspondre à une valeur supérieure à celle limite de talonnement en sorte de permettre d'anticiper le talonnement, et ainsi ne pas atteindre celui-ci.The predetermined depth corresponds to the limit threshold of bottleneck. It can also correspond to a value greater than the limit of bottleneck so as to allow to anticipate the bottleneck, and thus not reach it.

Selon une forme de réalisation préférentielle de cette autre variante du dispositif selon l'invention, il comporte un circuit imprimé relié à une connexion électrique et comprenant au moins deux bornes distantes, ces dernières étant destinées à coopérer avec un élément déformable réalisé en matériau conducteur électriquement séparé desdites bornes par un élément intercalaire évidé, réalisé en matériau isolant électriquement, ledit élément déformable étant apte à être forcé dans ledit élément intercalaire sous le déplacement de la paroi supérieure, en direction de la paroi inférieure, et à établir une liaison entre lesdites bornes à partir d'un certain niveau de déplacement.According to a preferred embodiment of this other variant of the device according to the invention, it comprises a printed circuit connected to an electrical connection and comprising at least two distant terminals, the latter being intended to cooperate with a deformable element made of electrically conductive material separated from said terminals by a hollow intermediate element, made of electrically insulating material, said deformable element being able to be forced into said intermediate element under the displacement of the upper wall, in the direction of the lower wall , and to establish a connection between said terminals from a certain level of displacement.

Outre le fait que le dispositif selon l'invention permette de résoudre le problème posé, ce mode de réalisation présente l'avantage de pouvoir réaliser un contact sans créer de point dur sur le corps du patient.In addition to the fact that the device according to the invention solves the problem, this embodiment has the advantage of being able to make contact without creating a hard spot on the body of the patient.
Le circuit imprimé 21 peut être plus ou moins complexe, c'est-à-dire, par exemple, prévu apte à permettre de repérer l'emplacement du ou des contacts, autorisant ainsi la localisation des zones qui présentent un risque.The printed
En référence maintenant à la figure 5, on peut voir un autre mode de réalisation du dispositif selon l'invention. On retrouve un support gonflable 1, une paroi inférieure ou alèse 2 et une paroi supérieure 3 constituée d'une juxtaposition d'alvéoles 30, dont en l'occurrence un seul est représenté.Referring now to Figure 5, we can see another embodiment of the device according to the invention. There is an
Dans ce mode de réalisation, la paroi inférieure ou alèse 2 présente une partie 25 déformable qui présente un profil permettant de superposer, à une certaine distance l'une de l'autre, deux électrodes 26 et 27, en sorte que l'enfoncement de l'alvéole 30, au-delà d'un certain seuil, provoque la déformation de la partie 25 jusqu'à mettre en contact les deux électrodes 26 et 27.In this embodiment, the bottom wall or
On notera que ce mode de réalisation permet d'envisager des mesures de plusieurs seuils au même emplacement.It should be noted that this embodiment makes it possible to envisage measurements of several thresholds at the same location.
On notera également que ce mode de réalisation peut être appliqué à un support autre que gonflable, en mousse souple par exemple, dans lequel sont prévus des moyens, tels qu'une cavité par exemple, pour permettre l'entrée ou non en contact des deux électrodes.Note also that this embodiment can be applied to a support other than inflatable, flexible foam for example, wherein are provided means, such as a cavity for example, to allow the entry or not in contact with the two electrodes.
En référence maintenant à la figure 6, on peut voir un autre mode de réalisation du dispositif selon l'invention, dans lequel est disposée au droit d'une alvéole 30, une cellule 6 gonflée à une certaine pression et s'étendant sur une certaine hauteur entre la paroi inférieure ou alèse 2, et la paroi supérieure 3.Referring now to Figure 6, we can see another embodiment of the device according to the invention, wherein is disposed in line with a
Lorsque la quantité d'air dans l'élément gonflable 1 n'est pas suffisante, la paroi supérieure 3 vient comprimer la cellule 6, et par la mesure de la pression interne de cette dernière on peut détecter un risque de talonnement.When the amount of air in the
La cellule 6 peut être solidaire aussi bien de la paroi inférieure 2 que la paroi supérieure 3, mais également être entièrement libre.The
Dans ce mode de réalisation, le signal émis peut être aussi bien un signal d'origine électrique, qu'un signal d'origine pneumatique.In this embodiment, the transmitted signal may be both an electrical source signal, a pneumatic origin signal.
En référence maintenant à la figure 7 on peut voir un autre mode de réalisation du dispositif selon l'invention, où la paroi inférieure 2 est munie d'un moyen émetteur 28, et la paroi supérieure 3 d'un moyen récepteur 31, ou inversement.Referring now to Figure 7 we can see another embodiment of the device according to the invention, wherein the
Les moyens émetteur 28 et récepteur 31 sont aptes à permettre de mesurer, de manière précise si nécessaire, la distance qui les sépare, en sorte que, lorsque cette distance passe en deçà d'une certaine valeur, puisse être émis un signal.The transmitter means 28 and
Ce mode de réalisation peut également être utilisé pour équiper des supports en mousse souple, les moyens émetteur et récepteur étant placés intérieurement, sous la surface du côté supérieur et sous la surface du côté inférieur.This embodiment can also be used to equip flexible foam supports, the transmitter and receiver means being located internally, below the surface of the upper side and under the surface of the lower side.
