Abstract

The immobilizing mat (1), made from upper and lower PVC layers (2, 3) and filled with polystyrene balls (5) which allow it to go rigid when air is extracted from it through a valve (6), has a strip (7) of PVC fabric stuck to the inside of its upper layer to prevent lengthwise retraction. The strip is slightly shorter than the overall length of the mat, leaving a small gap at each end, and has a narrow section at one end.

Description

<U>MATELAS</U> IMMOBILISATEUR ANTIRETRACTION La présente invention a pour objet un matelas immobilisateur antirétraction à dépression perfectionnée également appelé matelas immobilisateur antirétraction. . The present invention relates to an improved vacuum anti-retraction immobilizer mattress also referred to as an anti-retraction immobilizer mattress. .

On utilise de tels matelas pour immobiliser les personnes blessées ou accidentées notamment sur la voie publique. Ils sont constitués d'une enveloppe souple en PVC, résistante et imperméable à l'air, ladite enveloppe étant remplie de granules ou de billes de polystyrène et munie d'une valve permettant de faire le vide à l'intérieur de l'enveloppe. Such mattresses are used to immobilize injured or injured persons, especially on public roads. They consist of a flexible PVC jacket, resistant and impervious to air, said envelope being filled with granules or polystyrene beads and provided with a valve for evacuating the inside of the envelope.

De tels matelas sont utilisés pour immobiliser des polytraumatisés. Après avoir déposé le blessé sur sa surface, on fait le vide à l'intérieur du matelas. Such mattresses are used to immobilize polytraumatized. After placing the injured on its surface, the inside of the mattress is emptied.

Lorsque l'on fait ,le vide à l'intérieur de l'enveloppe constituant le matelas, celui-ci se rigidifie et se rétracte de plusieurs centimètres dans tous les sens et vient maintenir et enserrer les corps du blessé en l'entourant. When one makes, the emptiness inside the envelope constituting the mattress, this one stiffens and retracts several centimeters in all the directions and comes to maintain and grip the bodies of the wounded by surrounding it.

Si cette rétraction ne présente aucun inconvénient lorsqu'elle intervient dans le sens transversal, c'est-à-dire, en largeur, cette rétraction n'est pas souhaitable dans le sens longitudinal c'est-à-dire en longueur, car dans ce cas la rétraction produit sur le blessé un effet de compression au niveau de l'axe longitudinal de l'organisme, autrement dit, sur la colonne vertébrale du patient dont les effets indésirables sont à redouter sur les traumatisés du rachis. If this retraction presents no inconvenience when it occurs in the transverse direction, that is to say, in width, this retraction is not desirable in the longitudinal direction that is to say in length, because in In this case, the retraction produces a compression effect on the injured person at the level of the longitudinal axis of the body, in other words, on the patient's spine, the undesirable effects of which are to be feared on the traumatized spine.

On a essayé de remédier à cet inconvénient par l'introduction, dans les matelas connus de dispositifs antirétractation constitués par des tubes disposés dans le sens longitudinal pour empêcher ladite rétraction. On a également essayé de disposer des bandes alternées de différentes matières plus ou moins élastiques afin de limiter la rétractation longitudinale sans pour autant empêcher la rétractation transversale. Car si la rétractation du matelas immobilisateur ne doit pas appuyer sur le sommet de la tête et sur les pieds du blessé, elle doit maintenir fermement celui-ci de chaque côté. Certains ont utilisé un élément rigide constitué par une plaquette étroite en bois en matière plastique disposée dans l'axe longitudinal du matelas et maintenue en place dans une poche prévue à cet effet. Cette réalisation ne permet pas le repliement du matelas lorsqu'il n'est pas utilisé. De plus, il nécessite de confectionner une poche sur la face intérieure du matelas entraînant un coût de fabrication plus élevé. An attempt has been made to overcome this disadvantage by introducing into the known mattresses anti-retraction devices constituted by tubes arranged in the longitudinal direction to prevent said retraction. It has also been attempted to arrange alternating strips of different more or less elastic materials to limit longitudinal shrinkage without preventing transverse shrinkage. For if the retraction of the immobilizing mattress should not press the top of the head and the feet of the injured, it must firmly hold the latter on each side. Some have used a rigid element consisting of a narrow wooden plastic wafer disposed in the longitudinal axis of the mattress and held in place in a pocket provided for this purpose. This embodiment does not allow the folding of the mattress when not in use. In addition, it requires making a pocket on the inner face of the mattress resulting in a higher manufacturing cost.

La Demanderesse a procédé .à différents essais sur des matelas antirétractation existants afin de s'affranchir des contraintes de fabrication énumérées ci-dessus. The Applicant has carried out various tests on existing anti-retraction mattresses in order to overcome the manufacturing constraints listed above.

La Demanderesse a constaté, après plusieurs essais, que l'on pouvait supprimer la plaquette de rigidification existante et également les autres dispositifs existants et obtenir un résultat meilleur en collant une simple toile caoutchoutée sur la face intérieure de l'enveloppe du matelas. The Applicant has found, after several tests, that one could remove the existing stiffening plate and also other existing devices and get a better result by sticking a simple rubberized fabric on the inside of the envelope of the mattress.

4n peut également utiliser une toile PVC 1000 deniers semblable à celle constituant l'enveloppe. Cette toile peut être découpée facilement, ce qui permet de lui donner la configuration que l'on désire. Généralement, elle se présente sous la forme d'une bande de 25 centimètres de largeur et de 1,70 m de long ; une de ses extrémités correspondant à la tête du blessé sera plus étroite. Cette bande de PVC 1000 deniers sera contrecollée suivant l'axe longitudinal du matelas.  It is also possible to use a 1000 denier PVC fabric similar to that constituting the envelope. This canvas can be cut easily, which allows to give it the configuration you want. Generally, it is in the form of a band 25 centimeters wide and 1.70 meters long; one of its extremities corresponding to the wounded's head will be narrower. This 1000 denier PVC tape will be laminated along the longitudinal axis of the mattress.

Toutefois la bande contre collée doit être légèrement plus courte que la longueur du matelas. Ses deux extrémités doivent s'arrêter à quelques centimètres du bord du matelas. En effet, lors d'essais, la Demanderesse a constaté que lorsque la bande contre collée s'étendait sur toute la longueur du matelas, celui-ci avait tendance, lorsque l'on faisait le vide à l'intérieur de l'enveloppe, à se rétracter en longueur. Par contre, si la bande contre collée s'arrête à quelques centimètres du bord du matelas, il ne se rétracte pas lorsque l'on fait le vide dans l'enveloppe. However the tape against glued must be slightly shorter than the length of the mattress. Both ends must stop a few inches from the edge of the mattress. Indeed, during tests, the Applicant has found that when the tape against glued extended over the entire length of the mattress, it had a tendency, when it was evacuated inside the envelope, to retract in length. On the other hand, if the tape against glued stops a few centimeters from the edge of the mattress, it does not retract when one empties in the envelope.

La Demanderesse a également constaté que lorsque l'on fait le vide dans l'enveloppe, les billes de polystyrène se rétractent de manière connue par écrasement les unes contre les autres provoquant le serrage et le maintien du corps du patient à l'exception de la surface délimitée par la bande contre collée à l'enveloppe. En effet, les billes de polystyrène agglomérées sous la bande contre collée provoquent sa rigidification empêchant toute rétraction en deçà de son pourtour. The Applicant has also found that when the envelope is evacuated, the polystyrene balls retract in a known manner by crushing against each other causing the tightening and the holding of the body of the patient with the exception of the surface bounded by the tape against glued to the envelope. In fact, the polystyrene beads agglomerated under the adhesive-bonded strip cause its stiffening preventing any shrinkage below its periphery.

En conséquence, la rétraction transversale du matelas selon l'invention peut s'effectuer normalement et enserrer le corps du patient, mais la rétraction longitudinale ne peut s'effectuer sur la longueur de la bande contre collée. Accordingly, the transverse retraction of the mattress according to the invention can be carried out normally and grip the patient's body, but the longitudinal retraction can not be performed along the length of the tape against glued.

L'invention sera mieux comprise à la lecture de la description d'une de ses réalisations et à l'examen du.dessin annexé sur lequel La figure 1 est une vue en plan du matelas immobilisateur selon l'invention. The invention will be better understood on reading the description of one of its embodiments and on examining the appended drawing on which FIG. 1 is a plan view of the immobilizing mattress according to the invention.

La figure 2 est une vue en coupe dudit matelas selon la ligne 2-2 de la figure 1. Figure 2 is a sectional view of said mattress along the line 2-2 of Figure 1.

Comme représenté sur les figures 1 et 2, le matelas immobilisateur anti rétraction selon l'invention est constitué d'une enveloppe 1 formée de deux parois 2 et 3 de forme octogonale en PVC 1000 deniers, résistant et imperméable à l'air, assemblées à leur pourtour par collage 4. Cette enveloppe 1 est remplie de billes de polystyrène 5 et munie d'une valve 6 permettant de faire le vide à l'intérieur. As represented in FIGS. 1 and 2, the anti-retraction immobilizer mattress according to the invention consists of a casing 1 formed of two walls 2 and 3 of octagonal shape made of 1000 denier PVC, resistant and impervious to air, assembled at 4. This envelope 1 is filled with polystyrene beads 5 and provided with a valve 6 for evacuating the interior.

Sur la paroi supérieure, à l'intérieur, on dispose par collage une bande étroite et longue 7 préalablement découpée en PVC 1000 deniers. Le collage est effectué au moyen d'une colle synthétique polymérisable que l'on trouve dans le commerce. On the upper wall, inside, is provided by gluing a narrow strip and long 7 previously cut in 1000 denier PVC. The bonding is carried out by means of a polymerizable synthetic glue which is commercially available.

Cette bande 7 contre collée suivant l'axe longitudinal X-X du matelas 1 sera légèrement plus courte afin de laisser un espace E entre chacune de ses extrémités et le bord 4 du matelas (figure 1). This strip 7 against glued along the longitudinal axis X-X of the mattress 1 will be slightly shorter to leave a space E between each of its ends and the edge 4 of the mattress (Figure 1).

A titre d'exemple, pour un matelas immobilisateur mesurant 2,20 m de longueur sur 0,85 m de largeur, la bande contre collée mesurera 1,70 m de long sur 0,25 m de large. For example, for an immobilizing mattress measuring 2.20 m long and 0.85 m wide, the bonded tape will be 1.70 m long and 0.25 m wide.

L'extrémité 7A destinée à être sous la tête du blessé est plus étroite afin de permettre, lors de la rétraction, le maintien de la tête de chaque côté. The end 7A intended to be under the head of the injured is narrower to allow, during retraction, the maintenance of the head on each side.

Lorsque l'on fait le vide dans le matelas immobilisateur, la rétraction transversale peut s'effectuer sans problème alors que la rétraction longitudinale est impossible. Par ailleurs, lorsque le matelas est rempli d'air par ouverture de la valve 6, l'enveloppe devient molle et on peut facilement le replier pour son magasinage. When the immobilizing mattress is evacuated, the transverse retraction can proceed smoothly while the longitudinal retraction is impossible. Moreover, when the mattress is filled with air by opening the valve 6, the envelope becomes soft and can be easily folded for storage.

Bien entendu, dans la réalisation représentée, on n'a pas décrit les poignées de portage, les sangles destinées à maintenir le blessé, la valve, tous ses éléments étant largement utilisés et connus. De même, les matériaux employés sont perméables aux rayons X.Of course, in the embodiment shown, it has not described the carrying handles, the straps intended to maintain the injured, the valve, all its elements being widely used and known. Similarly, the materials used are permeable to X-rays.
