Abstract

The invention relates to an improvement to anti-bedsore mattresses. This improvement lies in the fact that an internal wall (1) makes it possible to obtain a substantial thickness, without the assembly being displaced during inflation and deflation. Another advantage is that it is possible to use low pressures, which improves very distinctly the comfort of the patient and the efficacy of the assembly. <IMAGE>

Description

La présente invention concerne une amélioration aux matelas alternatifs anti-escarres.The present invention relates to an improvement to alternative anti-decubitus mattresses.

Ces matelas, bien connus, sont utilisés dans les hôpitaux ou à domicile pour la prévention ou le traitement des escarres.These well-known mattresses are used in hospitals or at home for the prevention or treatment of bedsores.

Les matelas ou sur-matelas sont en général fabriqués suivant deux modèles principaux :

  • 1) par soudage de deux feuilles plastiques formant au gonflage des éléments gonflables parallèles, longitudinaux, transversaux ou en diagonale, reliés entre-eux par séries paires et impaires, gonflées alternativement. On peut utiliser également des formes en points ou en boules.
    Ce système présente plusieurs défauts :
    • a) au gonflage, l'ensemble se rétracte, et en raison des alternances, il se produit un mouvement d'auto-reptation qui oblige à une remise en place fréquente du matelas.
    • b) de par sa conception, il n'autorise pas des éléments gonflables ou des points très épais et nécessite une pression relativement forte, jusqu'à 150 hPa, pour être efficace ce qui le rend inconfortable pour le malade.
    • c) en raison de sa forme et de la largueur des soudures, la surface en contact avec le corps représente parfois seulement à chaque alternance, le tiers de la surface générale.
  • 2) Aussi, a-t-on été amené à faire des matelas à gros éléments gonflables, généralement interchangeables et, soit les maintenir par des rubans plastiques, soudés sur une base lisse, soit les introduire dans des housses alvéolées difficiles à fabriquer et à désinfecter.
Mattresses or over-mattresses are generally produced according to two main models:
  • 1) by welding of two plastic sheets forming, upon inflation, inflatable elements which are parallel, longitudinal, transverse or diagonal, connected to one another by even and odd series, inflated alternately. You can also use point or ball shapes.
    This system has several faults:
    • a) upon inflation, the assembly retracts, and due to the alternations, there is a self-crawling movement which requires frequent replacement of the mattress.
    • b) by design, it does not allow inflatable elements or very thick points and requires a relatively high pressure, up to 150 hPa, to be effective which makes it uncomfortable for the patient.
    • c) because of its shape and the width of the welds, the surface in contact with the body sometimes represents only at each alternation, a third of the general surface.
  • 2) Also, have we been led to make mattresses with large inflatable elements, generally interchangeable and either maintain them by plastic tapes, welded on a smooth base, or introduce them in honeycomb covers difficult to manufacture and to disinfect.

L'objet de la présente invention est d'éviter au mieux ces inconvénients.The object of the present invention is to best avoid these drawbacks.

Dans ce but, la présente invention consiste en un matelas formé de structures telles que des éléments gonflables, cellules, enceintes ou toute autre forme convenable, et désignée par élément gonflable dans ce qui suit, comportant une paroi interne (1) donnant une dimension déterminée en largeur et de ce fait, une dimension fixe à l'ensemble, quelle que soit la hauteur choisie, par les dimensions des demi-enveloppes supérieure (2) et inférieure (3) qui déterminent la hauteur. Les éléments gonflables ainsi formés ne se chevauchant pas, ils peuvent être fabriqués par unité, par groupe de 2, 3 ou plus, ou sous forme d'un matelas monobloc.For this purpose, the present invention consists of a mattress formed of structures such as inflatable elements, cells, enclosures or any other suitable shape, and designated by inflatable element in the following, comprising an internal wall (1) giving a determined dimension in width and therefore a dimension fixed to the assembly, whatever the height chosen, by the dimensions of the upper (2) and lower (3) half-envelopes which determine the height. The inflatable elements thus formed do not overlap, they can be manufactured per unit, in groups of 2, 3 or more, or in the form of a one-piece mattress.

Ces élements gonflables peuvent comporter une ou plusieurs soudures transversales ou longitudinales (6) ménageant un espace non gonflé, créant ainsi un vide entre matelas et malade à l'emplacement d'un pansement ou d'une cicatrice.These inflatable elements may include one or more transverse or longitudinal welds (6) providing an uninflated space, thus creating a vacuum between mattress and patient at the location of a dressing or a scar.

L'emplacement en question peut être réalisé par une paroi interne seule créant un espace libre entre deux élements gonflables ou en débranchant l'élément gonflable correspondant, afin de ne pas le gonfler à l'emplacement prévu.The location in question can be achieved by an internal wall alone creating a free space between two inflatable elements or by disconnecting the corresponding inflatable element, so as not to inflate it at the intended location.

Ces élements gonflables peuvent également comprendre deux ou plus de deux parois internes (1) semblables à la paroi interne (1), parallèles et superposées, permettant une hauteur plus grande et une largeur équivalente.These inflatable elements can also comprise two or more of two internal walls (1) similar to the internal wall (1), parallel and superimposed, allowing a greater height and an equivalent width.

Les élements gonflables ou groupe d'éléments gonflables peuvent être reliés entre eux par des lacets passant dans des perforations, des boutons pressions, des fermetures adhésives ou a glissière, ou tout autre système (5).The inflatable elements or group of inflatable elements can be linked together by laces passing through perforations, snaps, adhesive or zipper closures, or any other system (5).

La pression utilisée pourra être faible, ce qui améliorera le confort sans affecter l'efficacité et le très léger écrasement fera que le corps du malade reposera sur au moins la moitié de sa surface.The pressure used may be low, which will improve comfort without affecting efficiency and the very slight crushing will cause the patient's body to rest on at least half of its surface.

La paroi interne (1) pourra être perforée ou présenter une longueur plus faible que les enveloppes supérieure (2) et inférieure (3), laissant ainsi un passage aux extrémités pour équilibrer les deux demi- éléments gonflables. Les éléments gonflables seront généralement reliés par séries paires et impaires, par des raccords et tuyaux appropriés.The internal wall (1) may be perforated or have a shorter length than the upper (2) and lower (3) envelopes, thus leaving a passage at the ends to balance the two inflatable half-elements. The inflatable elements will generally be connected in even and odd series, by appropriate fittings and pipes.

L'invention va maintenant être expliquée à l'aide des figures jointes.

  • La figure 1 représente une vue en coupe dans laquelle (1) désigne la paroi interne, (2) et (3) les deux demi-enveloppes, (4) les soudures d'un élément gonflable à l'état gonflé, (5) les perforations utilisées pour relier les éléments entre eux.
  • La figure 2 représente une vue en coupe d'un élément gonflable comportant une soudure centrale (6) créant une moindre hauteur entre deux éléments gonflables adjacents.
  • La figure 3 représente une vue en coupe d'un élément gonflable comprenant plusieurs soudures centrales (6).
  • La figure 4 représente un élément gonflable comportant plusieurs parois internes (1) afin d'obtenir une hauteur plus grande pour une même largeur.
The invention will now be explained using the attached figures.
  • FIG. 1 represents a sectional view in which (1) designates the internal wall, (2) and (3) the two half-envelopes, (4) the welds of an inflatable element in the inflated state, (5) the perforations used to connect the elements together.
  • 2 shows a sectional view of an inflatable element comprising a central weld (6) creating a lower height between two adjacent inflatable elements.
  • Figure 3 shows a sectional view of an inflatable element comprising several central welds (6).
  • FIG. 4 represents an inflatable element comprising several internal walls (1) in order to obtain a greater height for the same width.

L'air peut être remplacé par un autre fluide tel que de l'eau.Air can be replaced by another fluid such as water.

L'invention fonctionne de la façon suivante : Les éléments gonflables regroupés par séries paires impaires sont gonflés alternativement. Ils peuvent également rester gonflés en permanence.The invention operates as follows: The inflatable elements grouped in odd even series are inflated alternately. They can also remain permanently inflated.
