Abstract
Description
La présente invention entre dans le domaine médical et paramédical, plus particulièrement dans l'assistance à l'alitement de patient.The present invention is in the medical and paramedical field, more particularly in assistance with patient bed rest.
L'invention concerne un dispositif d'alitement de type matelas gonflable, intégrant un gyroscope.The invention relates to an inflatable mattress bedding device, incorporating a gyroscope.
De manière connue, l'alitement prolongé d'un patient entraîne la formation d'escarres, à savoir des lésions cutanées liées à une compression des tissus mous avec le matelas. Pour prévenir la formation d'escarre, les lits sont équipés de matelas gonflables à air, approvisionnés par un compresseur. La pression d'air à l'intérieur du matelas est calculée en fonction de la morphologie du patient.In known manner, the prolonged bed rest of a patient causes the formation of bedsores, namely skin lesions related to compression of the soft tissues with the mattress. To prevent bedsores, the beds are equipped with inflatable air mattresses, supplied by a compressor. The air pressure inside the mattress is calculated according to the morphology of the patient.
Un inconvénient réside dans le changement de décubitus d'un patient, lors de son passage d'une position allongée à assise, ou inversement.A disadvantage lies in the change of a patient's decubitus, during his passage from an extended position to sitting, or vice versa.
On notera que le changement de position s'effectue généralement par levage de la partie supérieure du lit, où repose le buste du patient, communément dénommée "relève-buste". Pour ce faire, les lits présentent une articulation et une motorisation adaptée pour lever et abaisser cette partie relève-buste.Note that the change of position is usually done by lifting the upper part of the bed, where rests the patient's bust, commonly referred to as "back-bust". To do this, the beds have a hinge and a motor adapted to lift and lower this part back-bust.
Lors de ce changement de stature, la répartition de la masse appliquée sur le matelas par le corps du patient change considérablement. En particulier, le poids appliqué au niveau du fessier augmente lorsque le patient est passe en position relevée, pour atteindre un maximum en position assise, et inversement. Sans modification de la pression, cette augmentation de la répartition de la masse peut provoquer un pincement ou "talonnement" des parois supérieure et inférieure du matelas, créant aussi un point de contact du fessier avec le sommier du lit. De plus, le matelas étant subdivisé intérieurement en cellules, cet appui plus important sur une zone limitée repousse l'air vers les autres cellules et en modifie la pression interne. Outre la détérioration potentielle du matelas, la prévention des escarres n'est alors plus assurée.During this change of stature, the distribution of the mass applied to the mattress by the body of the patient changes considerably. In particular, the weight applied to the buttock increases when the patient is in the raised position, to reach a maximum sitting position, and vice versa. Without changing the pressure, this increase in mass distribution can cause pinching or "bottlenecking" of the upper and lower walls of the mattress, creating a point of contact of the buttocks with the bed base. Moreover, since the mattress is internally divided into cells, this support is more important on a limited area pushes the air towards the other cells and modifies the internal pressure. In addition to the potential deterioration of the mattress, prevention of pressure ulcers is no longer ensured.
Actuellement, les compresseurs sont équipés de moyens de commande permettant d'augmenter ou de diminuer manuellement la pression interne du matelas. Un opérateur doit alors modifier la pression à chaque changement de position. En particulier, on augmente la pression du matelas ou des cellules de la zone supportant le fessier, lors de la mise en position assise, et inversement.Currently, the compressors are equipped with control means for manually increasing or decreasing the internal pressure of the mattress. An operator must then change the pressure at each change of position. In particular, it increases the pressure of the mattress or cells of the area supporting the buttocks, when sitting and vice versa.
Cette opération manuelle présente l'inconvénient d'obliger l'opérateur, le plus souvent le personnel hospitalier, à intervenir sur le compresseur, alors qu'il doit s'occuper en même temps du patient. Parfois, l'opérateur n'est pas informé ni formé à l'utilisation du compresseur, ne modifiant pas la pression.This manual operation has the disadvantage of requiring the operator, most often the hospital staff, to intervene on the compressor, while he must attend to the patient at the same time. Sometimes the operator is not informed or trained to use the compressor, not changing the pressure.
Des systèmes existants tentent de pallier cet inconvénient en modifiant la pression automatiquement par passage de palliés. De tels systèmes sont rapportés sur le matelas et peuvent être reliés à la motorisation du relève-buste et, lors du passage de seuils d'inclinaison du relève-buste, augmentent la pression ou la diminuent. En particulier, un seuil de déclenchement de l'augmentation de la pression est situé à 30°.Existing systems attempt to overcome this disadvantage by changing the pressure automatically by passing palliated. Such systems are reported on the mattress and can be connected to the motor of the backrest and, during the passage of inclination thresholds of the backrest, increase the pressure or decrease. In particular, a threshold for triggering the increase in pressure is located at 30 °.
Un exemple de ce fonctionnement est décrit au travers du document
Si l'opérateur n'a plus à se soucier de modifier manuellement la pression, de tels systèmes modifient la pression du matelas par passage de paliers, entrainant une baisse du confort pour le patient et n'empêchant pas, lors du changement de pression, le risque de talonnement du matelas le temps que la pression soit stabilisée audit pallié, en particulier lors d'une augmentation de pression. En effet, le compresseur ne peut pas augmenter ou diminuer instantanément la pression. Par ailleurs, le matelas doit alors être relié à la motorisation du lit, entraînant des obligations techniques de compatibilité coûteuses à surmonter et limitant forcément cette compatibilité vue le grand nombre de matelas et de lits existants.If the operator does not have to worry about manually changing the pressure, such systems change the pressure of the mattress by passing bearings, causing a decrease in comfort for the patient and does not prevent, during the pressure change, the risk of the mattress settling until the pressure is stabilized at said palliated, especially during an increase in pressure. Indeed, the compressor can not increase or decrease the pressure instantly. Furthermore, the mattress must then be connected to the motorization of the bed, resulting in expensive technical compatibility requirements to overcome and necessarily limiting this compatibility to the large number of mattresses and existing beds.
En outre, l'état de la technique vise à déterminer les changements de position du matelas au travers de ceux du lit, rendant dépendant le matelas et son compresseur avec la structure du lit.In addition, the state of the art aims to determine the changes in position of the mattress through those of the bed, making dependent the mattress and its compressor with the structure of the bed.
De plus, pour certaines morphologies de patient, un changement d'inclinaison du relève-buste de seulement 15° nécessite un changement de la pression interne du matelas, qui n'est actuellement pas réalisée.In addition, for certain patient morphologies, a change of inclination of the backrest of only 15 ° requires a change in the internal pressure of the mattress, which is currently not performed.
L'invention a pour but de pallier les inconvénients de l'état de la technique, en proposant de contrôler les variations d'inclinaison du relève-buste, même minimes, pour adapter en continu la pression interne du matelas.The invention aims to overcome the disadvantages of the state of the art, proposing to control variations of inclination of the backrest even small, to continuously adapt the internal pressure of the mattress.
En particulier, l'invention vise à dissocier le matelas pour le rendre totalement indépendant de la structure du lit. La présente invention réside dans le fait d'avoir combiné, directement audit matelas, à l'intérieur et au niveau de sa partie supérieure, et non au niveau de l'armature du lit, des moyens électroniques à même de détecter directement et précisément le moindre changement de l'angle d'inclinaison de ladite partie supérieure du matelas.In particular, the invention aims to dissociate the mattress to make it completely independent of the structure of the bed. The present invention lies in the fact of having combined, directly to said mattress, inside and at the level of its upper part, and not at the level of the frame of the bed, the electronic means capable of directly and accurately detecting the slightest change in the angle of inclination of said upper part of the mattress.
En effet, l'invention se concentre uniquement sur la partie du matelas constituant le dossier, en vue de modifier la pression interne des cellules du matelas situées au niveau de l'assise, voire de diminuer la pression de celles dudit dossier. Ce choix spécifique et précis provient du fait que le passage d'un décubitus allongé à assis, ou inversement, implique une modification importante de l'appui du corps (tandis que le soulèvement des jambes n'induit pas une fluctuation aussi forte).Indeed, the invention focuses solely on the portion of the mattress constituting the folder, to change the internal pressure of the cells of the mattress at the seat, or to reduce the pressure of those of said folder. This specific and precise choice comes from the fact that the transition from a supine position to sitting, or conversely, involves a significant modification of the support of the body (while the lifting of the legs does not induce such a strong fluctuation).
Pour ce faire, le matelas intègre un gyroscope uniquement au niveau du relève-buste, de manière à détecter tout changement d'inclinaison et modifier automatiquement et de façon continue la pression du matelas.To do this, the mattress incorporates a gyroscope only at the level of the backrest, so as to detect any change of inclination and automatically change and continuously the pressure of the mattress.
Pour ce faire l'invention concerne un dispositif d'alitement de type matelas gonflable comprenant une enveloppe hermétique et un compresseur pourvu d'un canal d'approvisionnement en air sous pression relié à ladite enveloppe, caractérisé par le fait qu'il comprend des moyens gyroscopiques intégrés à l'intérieur dudit matelas au niveau de sa partie supérieure, lesdits moyens gyroscopiques étant reliés à des moyens électroniques de régulation de la pression équipant ledit compresseur.To this end, the invention relates to an inflatable mattress bedding device comprising a hermetic envelope and a compressor provided with a pressurized air supply channel connected to said envelope, characterized in that it comprises means gyroscopic integrated inside said mattress at its upper part, said gyro means being connected to electronic means for regulating the pressure equipping said compressor.
Selon d'autres caractéristiques, aucunement limitatives, lesdits moyens gyroscopiques se présentent sous la forme d'un capteur de la position angulaire de ladite partie supérieure dudit matelas.According to other characteristics, in no way limiting, said gyroscopic means are in the form of a sensor of the angular position of said upper part of said mattress.
Avantageusement, ledit capteur mesure uniquement la position angulaire de la partie supérieure dudit matelas et lesdits moyens de régulation comprennent une unité de transcription en continu desdites positions mesurées en données de pressurisation et des moyens de communication audit compresseur de la pression de gonflage dudit matelas en fonction desdites données.Advantageously, said sensor only measures the angular position of the upper part of said mattress and said regulation means comprise a continuous transcription unit of said positions measured in pressurization data and means of communication to said compressor of the inflation pressure of said mattress according to said data.
Préférentiellement, ledit matelas comprend au niveau de sa partie supérieure au moins une cellule interne gonflable statique.Preferably, said mattress comprises at its upper part at least one static inflatable internal cell.
Selon un mode de réalisation, ledit dispositif comprend au moins une sangle en matériau élastique cousue en au moins deux points à une paroi intérieure latérale longitudinale dudit matelas, lesdits points de couture étant espacés de manière à recevoir en maintien lesdits moyens gyroscopiques.According to one embodiment, said device comprises at least one strap of elastic material stitched at at least two points to a longitudinal inner side wall of said mattress, said stitching points being spaced apart so as to receive said gyroscopic means.
De plus, lesdits points de couture peuvent coïncider avec les coutures existantes entre ladite paroi latérale longitudinale et les parois supérieure et inférieure dudit matelas.In addition, said stitches may coincide with existing seams between said longitudinal sidewall and the upper and lower walls of said mattress.
Selon un autre mode de réalisation, ledit dispositif comprend une partie amovible et que lesdits moyens gyroscopiques sont assujettis à ladite partie amovible.According to another embodiment, said device comprises a removable part and said gyroscopic means are subject to said removable part.

La présente invention concerne un dispositif d'alitement de type matelas gonflable 1.The present invention relates to a bed rest device of the inflatable type 1.
Un tel matelas 1 comprend une enveloppe hermétique 2 et un compresseur (non représenté) pourvu d'un canal d'approvisionnement 3 en air sous pression relié à ladite enveloppe 2.Such a mattress 1 comprises a
Selon le mode préférentiel de réalisation, ledit matelas 1 présente une forme parallélépipédique rectangle pourvu d'une paroi supérieure 4, d'une paroi inférieure 5, de deux parois latérales 6 s'étendant longitudinalement et de deux parois latérales 7 d'extrémités, lesdits parois 4,5,6,7 étant solidarisées entre elles au niveau de leurs bords adjacents respectifs, en particulier par des coutures intérieures.According to the preferred embodiment, said mattress 1 has a rectangular parallelepipedal shape provided with an upper wall 4, a
De plus, ledit matelas 1 comprend intérieurement des groupes distincts de cellules gonflables, approvisionnés de façon indépendante par ledit compresseur. En d'autres termes, les groupes de cellules présentent des pressions de gonflage différentes, en fonction de leur position au niveau dudit matelas 1. En outre, ledit compresseur comprend des moyens électroniques de régulation de la pression permettant de modifier la pression interne de chacun desdits groupes. En particulier, un groupe d'au moins une cellule gonflable est prévu statique, à savoir que la pression interne appliquée par ledit compresseur est stabilisée, restant constante ou approximativement constante, en dehors des phases de gonflage initiale du matelas 1 et de dégonflage total, ainsi que lors d'une étape de régulation initiale de la pression interne du matelas 1 en fonction des paramètres morphologiques du patient.In addition, said mattress 1 internally comprises distinct groups of inflatable cells, supplied independently by said compressor. In other words, the groups of cells have different inflation pressures, as a function of their position at said mattress 1. In addition, said compressor comprises electronic means for regulating the pressure making it possible to modify the internal pressure of each one. said groups. In particular, a group of at least one inflatable cell is provided static, namely that the internal pressure applied by said compressor is stabilized, remaining constant or approximately constant, outside the initial inflation phases of the mattress 1 and total deflation, as well as during a step of initial regulation of the internal pressure of the mattress 1 as a function of the morphological parameters of the patient.
Avantageusement, cette cellule statique ou ce groupe de cellules statiques se situe au niveau de la partie supérieure 8 dudit matelas 1, à savoir au niveau de la tête de lit où repose le buste du patient et coïncidant sur la plus grande partie de sa surface, avec la partie articulée en rotation du lit, dite "relève-buste".Advantageously, this static cell or group of static cells is located at the
A ce titre, comme évoqué précédemment, ledit lit comprend un relève-buste articulé en rotation, de manière à passer d'une position escamotée à relevée, passant par des positions intermédiaires, et inversement. Ces positions sont respectivement visibles sur les
Avantageusement, ledit dispositif de matelas 1 selon l'invention comprend des moyens gyroscopiques 9 intégrés à l'intérieur dudit matelas 1 au niveau de sa partie supérieure 8. De plus, lesdits moyens gyroscopiques 9 sont reliés à des moyens électroniques de régulation de la pression équipant ledit compresseur. Cette liaison peut s'effectue de façon filaire, au travers d'un câble 10 de communication et d'alimentation. Selon un autre mode de réalisation, lesdits moyens gyroscopiques 9 sont autonomes, intégrant une batterie et reliés audit compresseur par une liaison de communication sans fil.Advantageously, said mattress device 1 according to the invention comprises
On notera que le câble 10 présente une longueur suffisante par rapport à la longueur du matelas 1 et au canal d'approvisionnement en air 3, long duquel ledit câble 10 s'étend et est assujetti jusqu'à sa connexion avec ledit compresseur, notamment au sein d'une gaine de protection enfermant ledit canal 3 et le câble 10.It will be noted that the
Selon une caractéristique particulière, lesdits moyens gyroscopiques 9 se présentent sous la forme d'un capteur 11 de la position angulaire de ladite partie supérieure 8 dudit matelas 1. Dans ce mode préférentiel de réalisation, ledit capteur 11 ne fait que mesurer les variations de la position angulaire de la partie supérieure 8, sans les traiter et les communiquant directement au compresseur.According to a particular characteristic, said gyroscopic means 9 are in the form of a
A ce titre, ledit capteur 11 ne mesurant qu'uniquement la position angulaire de la partie supérieure 8 dudit matelas 1, lesdits moyens de régulation comprennent une unité de transcription en continu desdites positions mesurées. La transcription effectuée permet de traiter les positions mesurées et de les changer en données de pressurisation. Lesdits moyens de régulation comprennent alors des moyens de communication audit compresseur de la pression de gonflage dudit matelas 1, en particulier des groupes de cellules, en fonction desdites données transcrites.As such, said
A titre d'exemple, un traitement de transcription peut consister à augmenter la pression des cellules situées au niveau de l'assise du patient, lorsque une augmentation angulaire de la partie supérieure 8 est détectée, à savoir que le relève-buste passe dans une position relevée pour assoir le patient, et inversement. De plus, cette augmentation peut être prévue proportionnelle par rapport à la variation de l'angle détectée. En outre, l'augmentation de pression peut être modifiée par rapport aux pressions des groupes de cellules configurées initialement en fonction de la morphologie détectée.By way of example, a transcription treatment may consist in increasing the pressure of the cells situated at the level of the patient's seat, when an angular increase of the
Par exemple, pour une augmentation de l'angle de la partie supérieure 8 d'une valeur détectée de 10 degrés, alors la pression interne des cellules correspondantes peut être augmentée de 5 mbar (500 Pa), tandis que pour une augmentation de 35° la pression sera augmentée de 15 mbar (1500 Pa).For example, for an increase in the angle of the
Selon une caractéristique additionnelle, ledit matelas 1 comprend au moins une sangle 12 en matériau élastique cousue en au moins deux points, de préférence selon au moins deux lignes de coutures, à une paroi intérieure latérale longitudinale 6 dudit matelas 1. De plus, lesdits points de couture sont espacés de manière à recevoir en maintien lesdits moyens gyroscopiques 9. En somme, la sangle 12 est cousue sur l'intérieur du matelas 1, ménageant un espace à l'intérieur duquel est glissé le capteur 11, en déformant élastiquement ladite sangle 12. Ledit capteur 11 est alors maintenu, mais en cas de traction du son câble 10, alors il s'extrait dudit espace au lieu d'être arraché de son câble 10.According to an additional feature, said mattress 1 comprises at least one
On notera que ledit capteur 11 peut comprendre un boîtier extérieur conformé de manière à ménager en périphérie extérieure un décroché formant une gorge centrale s'étendant transversalement, permettant d'améliorer le maintien par rapport à ladite sangle 12 et aussi servir de détrompeur pour un positionnement optimal au sein du matelas 1.It will be noted that said
Selon une autre particularité, lesdits points de couture coïncident avec les coutures existantes entre ladite paroi latérale longitudinale 6 et les parois supérieure 4 et inférieure 5 dudit matelas 1. Cette fixation précise à ce niveau permet, d'une part, de coudre directement ladite sangle 12 au moment de la fabrication du matelas 1 et, d'autre part, de rendre ses coutures invisibles depuis l'extérieur.According to another feature, said stitching points coincide with the existing seams between said
Selon un autre mode de réalisation, ledit matelas 1 peut comprendre une partie amovible et lesdits moyens gyroscopiques sont assujettis à ladite partie amovible. En particulier, ladite partie amovible peut être un coussin gonflable, destiné à être positionné au niveau du relève-buste, voire une housse de recouvrement de toute ou partie dudit matelas 1, en particulier de cette partie amovible.According to another embodiment, said mattress 1 may comprise a removable part and said gyro means are subject to said removable part. In particular, said removable portion may be an airbag, intended to be positioned at the level of the backrest, or a covering cover of all or part of said mattress 1, in particular of this removable part.
Ainsi, le dispositif d'alitement de type matelas gonflable 1 selon l'invention permet de modifier en continu la pression interne des cellules ou groupes de cellules gonflables, en fonction des variations de l'inclinaison du relève-buste du lit. De plus, le fait que le matelas 1 intègre un gyroscope au niveau des cellules statiques de la partie supérieure 8, permet de limiter les mouvements de cette partie, alors que les pressions des autres cellules peut être modifiées, notamment dans le cadre d'un traitement de prévention des escarres. Le gyroscope ne subit donc pas ces mouvements, évitant une modification de la pression non désirée si aucune réelle inclinaison n'est réalisée au niveau du relève-buste.Thus, the bed resting device inflatable type 1 according to the invention allows to continuously change the internal pressure of cells or groups of inflatable cells, depending on the variations of the inclination of the backrest bust of the bed. In addition, the fact that the mattress 1 integrates a gyroscope at the level of the static cells of the
Par ailleurs, l'intégration d'un capteur électronique au niveau du matelas 1 permet d'introduire une mémoire interne, stockant des données et des caractéristiques propres à chaque matelas, notamment ses modes de fonctionnement et de pressurisation. Il est alors possible, directement en le connectant au compresseur, que ce dernier le reconnaisse et adapte automatiquement se gestion de la pression en fonction des données embarquées au sein de la mémoire dudit capteur 11.In addition, the integration of an electronic sensor level of the mattress 1 allows to introduce an internal memory, storing data and characteristics specific to each mattress, including its modes of operation and pressurization. It is then possible, directly by connecting it to the compressor, that the latter recognizes it and automatically adapts pressure management according to the data embedded in the memory of said
