Wound-covering article with preparation for attachment of a vacuum device

1. A wound-covering article configured for attachment to a vacuum device, said wound-covering article comprising:

a continuous, non-penetrated and undivided film element with reduced gas permeability that comprises a local thinning of penetrable or dividable material as a prearrangement, the local thinning of penetrable or dividable material being thinner than a portion of the film element surrounding the local thinning;

an absorption body configured to absorb liquid from wound exudate when placed on a wound and covered with the film element, said absorption body comprising hydro-active polymers selected from the group consisting of:

i) super-absorbing polymers (SAP) being a copolymer of acrylic acid and sodium acrylate;

ii) fibers of modified cellulose that are capable of converting into a gel by the absorption of liquid from-the wound exudate; and

iii) alginate fibers that are capable of converting into a gel body by the absorption of liquid from-the wound exudate; and

a coupling device configured to connect to said prearrangement,

said coupling device comprising a cannula, a blade, or a hollow needle for perforating the local thinning of the penetrable or dividable material to form a perforation in the local thinning for drawing a vacuum drawn on the wound using the vacuum device connected to the coupling device of the wound-covering article.

2. The wound-covering article according to claim 1 , wherein the prearrangement further comprises:

a) a marking that indicates a possible perforation position;

b) an opening that is closed with a cover; or

c) a flange for the coupling device.

3. The wound-covering article according to claim 1 , wherein the film element is gastight or permeable by water vapor.

4. The wound-covering article according to claim 1 , wherein the film element is transparent at least in sections and comprises a window opening through which material is removable from a wound area located underneath the wound-covering article when in use.

5. The wound-covering article according to claim 1 , wherein the absorption body comprises at least one laminar element of foam and fleece.

6. The wound-covering article according to claim 1 , wherein at least one edge of the wound covering article comprises a laminar adhesive element.

7. The wound-covering article according to claim 1 , wherein the prearrangement has a spacer for limiting a depth of the cannula, blade, or hollow needle during perforation of the local thinning.

8. The wound-covering article according to claim 1 , wherein the wound-covering article further comprises at least one other layer selected from the group consisting of:

a) a wound spacing lattice;

b) a layer with a high drying potential that drains off liquid;

c) a layer comprising modified cellulose;

d) a layer comprising silver or silver ions; and

e) a layer with bonding potential for bacteria.

9. The wound-covering article according to claim 1 , wherein the coupling device comprises at least one element selected from the group consisting of:

a) a flange counterpiece;

b) an adhesive layer; and

c) a compressible dome.

10. A kit for wound care comprising a wound-covering article according to claim 1 and one or more elements selected from the group consisting of:

a) a vacuum device;

b) a vacuum hose for connecting the coupling device to the vacuum device;

c) a filter membrane that allows gas to pass through the vacuum hose but prevents passage of liquid through the vacuum hose;

d) a non-return valve that prevents a backflow of evacuated liquid through the vacuum hose; and

e) a coupling for decoupling the wound-covering article the vacuum device without losing a previously established vacuum.

11. A method for treating a wound, the method comprising:

providing a wound-covering article according to claim 1 ;

placing the absorption body of the wound-covering article on the wound;

covering the absorption body with the film element of the wound-covering article;

connecting the coupling device of the wound-covering element to the prearrangement;

perforating the local thinning using the cannula, blade, or hollow needle of the coupling device to form a perforation in the local thinning; and

drawing a vacuum on the wound through the perforation in the local thinning using a vacuum device connected to the wound-covering article by the coupling device.
