Patent Images
1. A device for therapeutic treatment of wounds, said device comprising:
- a dressing for contact with a wound and provided with a dry hydrophilic layer for absorbing exudates from the wound, said layer, upon said contact, being free of sufficient hydrating material for electrical conductivity; and
electric supply means for circulating a current in said wound through said dressing, activation of said electric supply means being controlled by subsequent migration of exudates into said layer concomitantly with continuation of a process of exudate absorption by said layer.

Abstract
The invention concerns a device comprising a dressing provided with a layer (8) for absorbing the wound exudates and electric supply means (9) to circulate a current in said wound, through the dressing. The invention is characterized in that said layer (8) consists of a dry hydrophile substantially non-conductive layer at the time it is applied on the wound, the subsequent migration of the exudates into the thickness of said layer (8) controlling the activation of said electric supply means (9), concomitantly with the continuation of the process of exudate absorption by said layer (8).

14. A dressing for use in a device for therapeutic treatment of wounds and for contacting a wound when in use, said dressing comprising:
-
a dry hydrophilic layer for absorbing exudates from a wound, said layer being free of sufficient hydrating material for electrical conductivity when initially put into use; and
an electrode formed on a planar support and covered with said dry hydrophilic layer. - View Dependent Claims (15, 16, 17)

18. A device for therapeutic treatment of wounds, said device comprising:
-
a dressing for absorbing exudates from a wound when in use, said dressing including a dry hydrophilic layer which, when initially put into use, is free of sufficient hydrating material to effect electrical conductivity in said layer; and
electronic circuitry for circulating a current in said wound through said dressing, activation of said electronic circuitry being dependent upon exudate absorption by said layer. - View Dependent Claims (19, 20)
