Abstract

The cushion is made with the aid of a mould and a counter-mould of the required anatomical shape. A polyurethane pouch is injected with a polymerising material comprising isocyanates and polyols and placed in the mould during the last third of the polymerising time, and the counter-mould applied to it. A pressure can be applied to the counter-mould in a given area of the cushion in accordance with a medical prescription to produce a cushion which compensates for an asymmetrical sitting position.

Description

PROCEDE DE FABRICATION DE
COUSSINS ANTI ESCARRES
ET COUSSINS OBTENUS
La présente invention a pour objet un procédé de fabrication de coussins anti-escarres ainsi que le coussin obtenu.PROCESS FOR MANUFACTURING
ANTI-PRESSURE CUSHIONS
AND CUSHIONS OBTAINED
The present invention relates to a method of manufacturing anti-decubitus cushions as well as the cushion obtained.

II existe actuellement un certain nombre de coussins d'aide à la prévention d'escarres, en particulier des coussins réalisés en gel de polyuréthanne se composant d'une partie plane ce qui permet de répartir la pression au niveau de la zone à risques d'escarres;
Le principal inconvénient de ces coussins est de ne pas présenter de forme anatomique.There are currently a certain number of cushions to aid in the prevention of bedsores, in particular cushions made of polyurethane gel consisting of a flat part which makes it possible to distribute the pressure at the level of the risk zone. bedsores;
The main disadvantage of these cushions is that they do not have an anatomical shape.

Par ailleurs, il existe des coussins antiescarres ayant une forme anatomique formés de différents matériaux composés généralement d'un support et d'un gel (coussin mixte gel plus plaque de mousse) tel que le coussin commercialisé sous la marque ORTHOGEL et objet du brevet FR 2630644. Cette réalisation ne permet toutefois pas de corriger les assises dissymétriques. Furthermore, there are anti-square cushions having an anatomical shape formed from different materials generally composed of a support and a gel (mixed gel cushion plus foam plate) such as the cushion sold under the brand ORTHOGEL and subject of the patent FR 2630644. This achievement does not, however, allow the asymmetrical foundations to be corrected.

La présente invention a pour objet de remédier aux inconvénients énumérés ci-dessus. Elle concerne un procédé de fabrication de coussins antiescarres en gel de polyuréthanne de forme anatomique permettant d'améliorer nettement les résultats obtenus;
La forme anatomique d'un coussin permet d'augmenter la surface de contact et de diminuer ainsi les zones à risques selon l'équation suivante:
P = Poids/surface.The object of the present invention is to remedy the drawbacks listed above. It relates to a process for manufacturing anti-square cushions in polyurethane gel of anatomical shape making it possible to clearly improve the results obtained;
The anatomical shape of a cushion makes it possible to increase the contact surface and thus to reduce the risk zones according to the following equation:
P = Weight / area.

Un tel coussin, selon l'invention permet d'avoir des compensations d'assises dissymétriques selon les prescriptions médicales, en modifiant son épaisseur en fonction des zones souhaitées par compression de la partie à corriger;
Le procédé de fabrication de coussins antiescarres selon l'invention est le suivant: dans ce procédé, on utilise un moule, un contre-moule et une poche en polyuréthanne. Le contre moule correspond à la conformation anatomique que l'on veut obtenir.Such a cushion, according to the invention makes it possible to have asymmetrical seat compensations according to medical prescriptions, by modifying its thickness as a function of the zones desired by compression of the part to be corrected;
The process for manufacturing anti-square cushions according to the invention is as follows: in this process, a mold, a counter-mold and a polyurethane pocket are used. The counter mold corresponds to the anatomical conformation that one wants to obtain.

On injecte tout d'abord dans la poche de polyuréthanne la matière de polymérisation constituée d'isocyanates et de polyols. On dépose ensuite ladite poche dans le moule, dans le demier tiers du temps de polymérisation et on applique le contre-moule. First, the polymerization material consisting of isocyanates and polyols is injected into the polyurethane bag. Said pocket is then deposited in the mold, in the last third of the polymerization time and the counter-mold is applied.

Suivant la prescription médicale, on agit sur le contremoule pour modifier par compression l'épaisseur du coussin sur la zone souhaitée. According to the medical prescription, one acts on the countermold to modify by compression the thickness of the cushion on the desired area.

Ce procédé de réalisation permet d'obtenir un coussin antiescarres de forme anatomique personnalisé pour chaque malade.  This production process makes it possible to obtain an anti-squares cushion of anatomical shape personalized for each patient.
