LIQUID-PERMEABLE PRIMARY DRESSING HAVING A FRACTION OF HEAVY METAL
The present invention relates to a fluid-permeable primary dressing in strip form, having pores, perforations or honeycomb lattices, which enable the passage of fluid, further having a content of at least one heavy metal present in elemental or ionic form.
1 . A fluid-permeable primary dressing in strip form, comprising: a plurality of pores, perforations or honeycomb lattices, wherein the plurality of pores, perforation, or honeycomb lattices enable the passage of fluid through the fluid-permeable primary dressing; and at least one heavy metal present in elemental or ionic form disposed within the fluid-permeable primary dressing.
2 . The primary dressing as claimed in claim 1 , wherein the at least one heavy metal present in elemental or ionic form is selected from the group comprising copper, zinc and/or silver.
3 . The primary dressing as claimed in claim 2 , wherein the primary dressing comprises a film having pores and/or perforations.
4 . The primary dressing as claimed in claim 3 , wherein the plurality of pores, perforations or honeycomb lattices are made in three-dimensional form.
5 . The primary dressing as claimed in claim 4 , characterized in that the primary dressing comprises a gauze or a fabric including the plurality of pores, perforations or honeycomb lattices.
6 . The primary dressing as claimed in claim 5 , wherein the primary dressing is a wound contact lattice.
7 . The primary dressing as claimed in claim 6 , wherein the at least one heavy metal present in elemental or ionic form are coated onto the primary dressing.
8 . The primary dressing as claimed in claim 7 , wherein at least one heavy metal present in elemental or ionic form is coextrued into the primary dressing.
9 . The primary dressing as claimed in claim 8 , wherein the primary dressing further comprises a plurality of punched holes, slits, incisions, or recesses that serve to facilitate the passage of fluid.
10 . A wound dressing having a covering which at least partially consists of a primary dressing as claimed in claim 9 .
11 . The wound dressing, as claimed in claim 10 , characterized in that said wound dressing contains a wound exudate-absorbing body.
12 . The wound care products as claimed in claim 11 , wherein the wound exudate-absorbing body has a pattern of incisions and/or punched holes.
13 . The wound care product as claimed in claim 12 , wherein the incisions and/or punched holes are formed and/or arranged such that they facilitate the entry of fluid into the wound care product.
14 . A method of using a primary dressing or a wound dressing as claimed in claim 9 , comprising: applying the primary dressing in a reduced pressure wound care system.
