Abstract

Wound dressing system for introduction into a wound, comprising at least one planar capillary membrane system, characterized in that the at least one planar capillary membrane system is arranged in a pouch-shaped wound dressing which is closed at its outer edge and which has an upper face, a lower face and a interior of the pouch, wherein the lower face and the upper face are each formed from a planar material, and the lower face is permeable to fluids, wherein the at least one planar capillary membrane system is arranged in the interior of the pouch and is connected to at least one supply line, such that liquids, media, gases and/or other substances can be conveyed through the supply line and the at least one capillary membrane system, and wherein the at least one supply line is connectable, outside the pouch-shaped wound dressing, to a unit for supply or disposal.

First claim

1 . A wound dressing system for introducing into a wound, comprising at least one planar capillary membrane system, characterized in that the at least one planar capillary membrane system is arranged in a pouch-shaped wound dressing, which is closed at its outer edge and which has an upper face, a lower face and a interior of the pouch,
wherein the lower face and the upper face are each formed from a two-dimensional material, and the lower face is permeable to fluids, wherein the at least one planar capillary membrane system is arranged in the interior of the pouch and is connected to at least one supply line, such that liquids, media, gases and/or other substances can be conveyed through the supply line and the at least one capillary membrane system, and wherein the at least one supply line is connectable to a supply unit or disposal unit outside the pouch-shaped wound dressing.

2 . The pouch-shaped wound dressing system according to claim 1 , characterized in that the lower face of the pouch-shaped wound dressing is formed from a nonwoven, two-dimensional material or a semi-permeable microporous flat membrane.

3 . The pouch-shaped wound dressing system according to claim 2 , characterized in that the lower face of the pouch-shaped wound dressing is formed from a semi-permeable microporous flat membrane.

4 . The pouch-shaped wound dressing system according to claim 1 , characterized in that the lower face of the pouch-shaped wound dressing has a water permeability of at least 0 . 01 mL/(min•cm 2. bar).

5 . The pouch-shaped wound dressing system according to claim 1 , characterized in that the lower face of the pouch-shaped wound dressing has openings.

6 . The pouch-shaped wound dressing system according to claim 1 , characterized in that the connection of the at least one planar capillary membrane system with the at least one supply line can be located in the interior of the pouch and the at least one supply line exits from the pouch-shaped wound dressing via a through-opening fitted to its external cross-section so as to be impermeable to fluids.

7 . The pouch-shaped wound dressing system according to claim 1 , characterized in that the connection of the at least one planar capillary membrane system with the at least one supply line is arranged on the upper face outside the pouch-shaped wound dressing, and the at least one planar capillary membrane system for connection to the at least one supply line exits from the pouch-shaped wound dressing via a through-opening fitted to be impermeable to fluids.

8 . The pouch-shaped wound dressing system according to claim 1 , characterized in that a drainage system is arranged in the interior of the pouch which is suitable for removing exudate from wounds to be treated.

9 . The pouch-shaped wound dressing system according to claim 8 , characterized in that the drainage system is a drainage catheter which exits from the pouch-shaped wound dressing via a through-opening fitted to its cross-section to be impermeable to fluids and is connectable to a vacuum unit.

10 . The pouch-shaped wound dressing system according to claim 1 , characterized in that the capillary membrane system is designed in the form of a mat of mutually parallel capillary membranes, wherein the capillary membranes in the mat are connected to one another by means of spaced and mutually parallel connection elements and are held at a distance from one another by the connection elements.

11 . The pouch-shaped wound dressing system according to claim 1 , characterized in that the capillary membranes are embedded with at least one of their ends in the at least one supply line.

12 . The pouch-shaped wound dressing system according to claim 11 , characterized in that the capillary membrane system is connected to two supply lines, wherein the capillary membranes are embedded with their opposite ends in a respective supply line.

13 . The pouch-shaped wound dressing system according to claim 1 , characterized in that the capillary membranes have a transmembrane flow for water in the range of 0.01 to 50 mL/(min•cm 2. bar).
