Abstract

The method involves inflating cell assemblies of a mattress with same pressure, and measuring internal pressure of the mattress when a patient is lying over the mattress. One of the cell assemblies is deflated such that the patient lies on the other assemblies. Pressure increase in the latter cell assemblies is measured, and the pressure due to the presence of the body of the patient is determined. The morphology of the patient is estimated, and a correlation between the pressure variation and the pressure level to be applied to the mattress is made.

Description

La présente invention a pour objet un procédé de détermination automatiqueThe present invention relates to an automatic determination method

de la pression de gonflage à appliquer à un matelas dynamique, en fonction de la morphologie du patient placé sur ledit matelas.  the inflation pressure to be applied to a dynamic mattress, depending on the morphology of the patient placed on said mattress.

Un tel procédé est destiné à équiper les matelas dynamiques du type comprenant plusieurs cellules gonflables susceptibles d'être gonflées et dégonflées en alternance selon une périodicité déterminée, afin de créer un mouvement de surface et ainsi modifier les points de pression entre le corps du patient et le matelas, pour éviter la formation d'escarres.  Such a method is intended to equip dynamic mattresses of the type comprising several inflatable cells that can be inflated and deflated alternately according to a determined periodicity, in order to create a surface movement and thus modify the pressure points between the body of the patient and the mattress, to prevent the formation of bedsores.

Il existe une pression de gonflage optimale, qui dépend essentiellement de la morphologie du patient, c'est-à-dire de la répartition de la masse. De plus, cette pression optimale peut être différente selon le type de travail à réaliser.  There is an optimal inflation pressure, which depends essentially on the morphology of the patient, that is to say, the distribution of the mass. In addition, this optimal pressure may be different depending on the type of work to be performed.

Les matelas dynamiques sont équipés de manomètres ce qui permet de régler la pression de gonflage, mais la pression optimale est déterminée de manière théorique en fonction d'une approximation de la morphologie.  The dynamic mattresses are equipped with manometers which makes it possible to regulate the inflation pressure, but the optimal pressure is determined theoretically according to an approximation of the morphology.

Cette manière de procéder est donc tout à fait aléatoire, 20 puisqu'elle ne prend en compte qu'une surface de contact estimée, qui peut être très éloignée de la réalité.  This way of proceeding is therefore quite random, since it takes into account only an estimated contact area, which can be very far from reality.

La présente invention a pour but de remédier à cet inconvénient, en proposant un procédé pour la détermination automatique de la pression de gonflage à appliquer à un matelas dynamique, en fonction de la morphologie du patient, quelle que soit la position de ce dernier.  The present invention aims to overcome this disadvantage, by providing a method for the automatic determination of the inflation pressure to be applied to a dynamic mattress, depending on the morphology of the patient, regardless of the position of the latter.

Le procédé de détermination automatique de la pression de gonflage à appliquer à un matelas dynamique, en fonction de la morphologie du patient placé sur ledit matelas, où ledit matelas est du type comprenant plusieurs cellules gonflables susceptibles d'être gonflées et dégonflées en alternance selon une périodicité déterminée afin de créer un mouvement de surface et ainsi modifier les points de pression entre le corps du patient et le matelas, ledit matelas comprenant au moins deux ensembles de cellules où les cellules de chacun desdits ensembles communiquent entre-elles, et où les cellules d'un ensemble sont réparties entre les cellules du ou des autres ensembles, et où ledit matelas est associé à des moyens de mesure de la pression interne de chacun desdits ensembles, des moyens de gonflage et de dégonflage de chacun desdits ensembles de cellules, ainsi que des moyens de traitement des informations recueillies par lesdits moyens de mesure, le procédé se caractérise essentiellement en ce qu'il consiste à réaliser successivement les opérations suivantes: gonfler toutes les cellules à une même pression, 10 - mesurer la pression interne du matelas lorsque le patient est couché dessus, -dégonfler au moins un ensemble de cellules, en sorte que le patient ne repose que sur les autres, - mesurer l'augmentation de la pression dans le ou les 15 autres ensembles de cellules gonflées, et déterminer la pression due à la présence du corps du patient, - estimer la morphologie du patient et faire une corrélation entre la variation de pression et le niveau de pression à appliquer au matelas.  The method of automatically determining the inflation pressure to be applied to a dynamic mattress, according to the morphology of the patient placed on said mattress, wherein said mattress is of the type comprising several inflatable cells that can be inflated and deflated alternately according to a periodicity determined to create a surface movement and thereby change the pressure points between the patient's body and the mattress, said mattress comprising at least two sets of cells where the cells of each of said sets communicate with one another, and where the cells of an assembly are distributed between the cells of the other assembly or sets, and wherein said mattress is associated with means for measuring the internal pressure of each of said sets, means for inflating and deflating each of said sets of cells, and that information processing means collected by said measuring means, the process is cara It essentially consists in successively performing the following operations: inflating all the cells at the same pressure, measuring the internal pressure of the mattress when the patient is lying on it, deflating at least one set of cells, that the patient relies only on the others, - measuring the increase of the pressure in the other 15 or more sets of inflated cells, and determining the pressure due to the presence of the patient's body, - estimating the morphology of the patient and making a correlation between the variation of pressure and the level of pressure to be applied to the mattress.
