Apparatuses and methods for wound therapy
Some embodiments of the present disclosure relate to a wound packing material, suitable for use in negative pressure wound therapy, comprising a body of a porous material, the body comprising frangible regions defining a plurality of portions, the frangible regions allowing the portions to be selectively removed from the body. The wound packing material can be shaped to partially or fully surround a secondary wound packing member, such as a stabilizing structure. Some embodiments further relate to methods of manufacturing the wound packing material, and to methods of its use.
1. A wound treatment apparatus comprising:
a unitary body consisting of a single porous material, the body comprising frangible regions defining a plurality of portions, the frangible regions allowing the portions to be selectively removed from the body so as to form a recess in the body, the recess being bound by a bottom surface and a wall portion; and
a secondary wound filler for positioning within the recess in the body.
2. The wound treatment apparatus of claim 1 , wherein the secondary wound filler comprises a superabsorber.
3. The wound treatment apparatus of claim 1 , wherein the secondary wound filler comprises a 3-D knitted fabric.
4. The wound treatment apparatus of claim 1 , wherein the secondary wound filler comprises a material configured to shed fibers or other particulates into the wound.
5. The wound treatment apparatus of claim 1 , wherein the portions can be removed manually.
6. The wound treatment apparatus of claim 1 , wherein the frangible regions are defined by pre-cuts formed in the body.
7. The wound treatment apparatus of claim 6 , wherein the pre-cuts are parallel.
8. The wound treatment apparatus of claim 7 , wherein the frangible regions are further defined by a second set of parallel pre-cuts formed in the body.
9. The wound treatment apparatus of claim 8 , wherein the frangible regions are further defined by a third set of parallel pre-cuts formed in the body.
10. The wound treatment apparatus of claim 6 , wherein the pre-cuts are formed via laser ablation.
11. The wound treatment apparatus of claim 6 , wherein the pre-cuts are formed via waterjet ablation.
12. The wound treatment apparatus of claim 6 , wherein the pre-cuts are formed via die-cutting.
13. The wound treatment apparatus of claim 1 , wherein the frangible regions are defined by a first set of parallel pre-cuts formed in the body.
14. The wound treatment apparatus of claim 1 , wherein the body of porous material is formed from a wound packing foam.
15. The wound treatment apparatus of claim 1 , wherein the body of porous material comprises a bottom portion, the bottom portion comprising a non-frangible section of porous material.
16. The wound treatment apparatus of claim 15 , wherein the bottom portion is 5-20 mm thick.
17. The wound treatment apparatus of claim 1 , further comprising a wound cover configured to be positioned over the unitary body and sealed to skin surrounding a wound.
18. The wound treatment apparatus of claim 17 , further comprising a source of negative pressure.
19. The wound treatment apparatus of claim 1 , wherein the body of porous material comprises a bowl shaped recess.
20. The wound treatment apparatus of claim 1 , wherein the body of porous material has a cubic shape.
