Title
(DE) VORRICHTUNG ZUR WUNDBEHANDLUNG UNTER EINSATZ VON UNTERDRUCK
(EN) DEVICE FOR THE TREATMENT OF WOUNDS USING A VACUUM
(FR) DISPOSITIF POUR TRAITER UNE PLAIE EN APPLIQUANT UNE DEPRESSION
Abstract
(DE) Die Erfindung betrifft eine Vorrichtung (100) zur Wundbehandlung des menschlichen oder tierischen Körpers unter Einsatz von Unterdruck, aufweisend: ein Wundabdeckungselement (4), das im am Körper des Patienten angelegten Zustand einen zwischen der jeweiligen Wunde und dem Wundabdeckungselement verbleibenden Wundraum (10) bildet, wenigstens eine Anschlussstelle (5.1), die mit dem Wundraum (10) in Kontakt steht, einen Absorptionskörper (2) der eine in eine Hülle eingefasste Lage eines mit superabsorbierenden Partikeln durchsetzen Textilabschnittes ist, wobei die Hülle flüssigkeitsdurchlässig ist und Poren aufweist, deren Grösse die der superabsorbierenden Partikeln nicht überschreitet. Der der in den Wundraum (10) einzulegende Absorptionskörper (2) weist ein Anfangsvolumen auf, das sich im Laufe des Absorptionsprozesses vergrössert und ein Endvolumen annimmt, so dass die absorbierten Wundsekrete - bedingt durch die Porengrössse der Hülle - innerhalb des Absorptionskörpers und damit unterhalb des Wundabeckungselementes bis zur Entfernung des Absorptionskörpers aus dem Wundraum verbleiben.
(EN) The invention relates to a device for treating wounds (100) on a human or animal using a vacuum. Said device comprises: a wound cover element (4), which when placed on the body of the patient creates a wound cavity (10) between the respective wound and the wound cover element; at least one connection point (5.1), which is in contact with the wound chamber (10); an absorption body (2), which is a cut textile section comprising interspersed super-absorbent particles and enclosed by a sleeve, the latter being permeable to liquid and having pores, whose size does not exceed that of the super-absorbent particles. The absorption body (2) that is to be placed in the wound cavity (10) has an initial volume that increases during the absorption process and reaches a final volume in such a way that the absorbed wound secretions, which are limited by the pore size of the sleeve, remain inside the absorption body and thus under the wound cover element, until the absorption body is removed from the wound cavity.
(FR) L'invention concerne un dispositif (100) pour traiter une plaie sur le corps d'un humain ou d'un animal en appliquant une dépression, ce dispositif comprenant les éléments suivants: un élément couvrant la plaie (4) et qui, lorsqu'il est appliqué sur le corps du patient, ménage un espace (10) entre la plaie et ledit élément; au moins un point de raccordement (5.1) en contact avec cet espace (10); un élément absorbant (2) formé d'une couche textile chargée de particules superabsorbantes, cette couche étant entourée d'une enveloppe perméable aux liquides et dotée de pores dont la dimension n'est pas supérieure à celle des particules. L'invention est caractérisée en ce que l'élément absorbant (2) à insérer dans l'espace (10) de la blessure présente un volume initial qui augmente durant le processus d'absorption pour atteindre un volume terminal, de sorte que les sécrétions absorbées de la plaie, du fait de la dimension des pores de l'enveloppe, restent à l'intérieur de l'élément absorbant, sous l'élément couvrant la plaie, jusqu'à l'enlèvement de l'élément absorbant hors de l'espace de la blessure.
