Abstract

A method of making a three-dimensional wound packing member is described, the method comprising the steps of: taking material selected from at least one of the following forms comprising perforated sheet, net, woven, non-woven and knitted material; subjecting the at least one material to at least one forming process selected from the processes comprising rolling into tubes, braiding, knotting and knitting to form a three-dimensional and resilient structural unit member for packing into a wound.

Claims (16)

1 . A method of making a three-dimensional wound packing member, the method comprising the steps of: taking material selected from the group consisting of perforated sheet, net, woven, non-woven and knitted material; subjecting the at least one material to at least one forming process selected from the group consisting of rolling into tubes, braiding, plaiting, knotting and knitting, so as to form a three-dimensional and resilient structural wound packing unit member for packing into a wound characterised by a porosity level of the wound packing unit member being controlled by a degree of tightness of said forming process.

2 . A method according to claim 1 wherein rolled tubes of the selected material are then formed into a resilient wound packing unit member by a forming process selected from the group consisting of braiding, plaiting, knotting and knitting, so as to form a resilient structural wound packing unit member.

3 . A method according to claim 1 wherein the individual wound packing member units are further treated by a technique selected from the group consisting of adhesively bonding, heat sealing and mechanically fixing to preserve a structural integrity of each wound packing unit member.

4 . A method according to claim 1 further comprising the step of linking together a plurality of the individual structural wound packing unit members so formed into a chain.

5 . A method according to claim 4 further comprising the step of cutting the chain into an appropriate number of units to suit a specific wound to be treated.

6 . A method according to claim 4 wherein the wound packing member units are linked by a thread.

7 . A method according to claim 6 wherein the thread is a plastics material monofilament.

8 . A method according to claim 1 wherein when the selected material is rolled into a tube, the porosity of the tube is partly controlled by the degree of tightness of rolling.

9 . A method according to claim 6 wherein a porosity of the resulting wound packing member unit is partly controlled by the degree of tightness of a plaiting, braiding, knitting or knotting step.

10 . A method according to claim 1 wherein materials comprising said wound packing member units do not adhere to growing tissue.

11 . A method of making a three-dimensional wound packing member according to claim 1 wherein a tube is first formed by rolling of the selected material and them forming said tube into a doughnut shape by rolling of the tube along its axis.

12 . A three-dimensional wound packing member unit comprising a material selected from the group consisting of perforated sheet, net, woven, non-woven and knitted material, wherein the material is processed so as to form a three-dimensional and resilient structural wound packing unit member, and wherein the wound packing member has a porosity level controlled by the processing.
