Compression dressing
There is provided herein a compression dressing comprising a first cushion layer ( 1 ) and a second support layer ( 2 ) wherein the two layers ( 1,2 ) are connected to each other in the unstretched state by means of a stich-bonding process via an elastic sewing thread, the stich length being 1.5 to 3mm/U at a sewing thread tension of at most 4 cN.
1. A compression bandage comprising a first cushioning layer ( 1 ) and a second supporting layer ( 2 ), wherein the first cushioning layer ( 1 ) and the second supporting layer ( 2 ) are connected to one another in an unstretched state via an elastic sewing thread by means of stitch-bonding where the stitch length is 1.5 to 3 mm at a sewing thread tension of not more than 4 cN, and wherein a material of the cushioning layer ( 1 ) and the supporting layer ( 2 ) is nonelastic and comprises a non-woven material; and wherein the compression bandage is only elasticized by means of stitch-bonding.
2. The compression bandage of claim 1 , wherein a thickness of the cushioning layer ( 1 ) is 0 . 6 - 1 . 2 mm.
3. The compression bandage of claim 1 , wherein the cushioning layer is comprised of a thermofusion nonwoven material.
4. The compression bandage of claim 1 , wherein the supporting layer ( 2 ) is comprised of a thermobond nonwoven material.
5. The compression bandage of claim 1 wherein the elastic sewing thread is selected from the group consisting of cotton spun crepe threads, cotton twisted crepe threads, textured polyamide yarns, textured polyester yarns, rubber threads, polyurethane elastane threads and combinations thereof.
6. The compression bandage of claim 1 , wherein the compression bandage has a stretching threshold which indicates a maximum stretchability.
7. The compression bandage of claim 6 , wherein the maximum stretchability corresponds to a therapeutically predefined application of the compression bandage configured to be on a limb of a wearer.
8. The compression bandage of claim 1 , wherein the compression bandage has an elastic modulus of 4-10 N/mm 2 .
9. The compression bandage of claim 1 , wherein the compression bandage has an increase in stretch of less than 50%.
10. A compression bandage combination comprising a first compression bandage as claimed in claim 1 , and also a second compression bandage.
11. The compression bandage combination of claim 10 , wherein the first compression bandage exerts a working pressure configured to be on a limb in an applied state and the second compression bandage a resting pressure.
12. The compression bandage of claim 8 , wherein the compression bandage has an elastic modulus of 5-9 N/mm 2 .
13. The compression bandage of claim 8 , wherein the compression bandage has an elastic modulus of 6-8 N/mm 2 .
14. The compression bandage of claim 9 , wherein the compression bandage has an increase in stretch of less than 35%.
15. The compression bandage of claim 9 , wherein the compression bandage has an increase in stretch of less than 25%.
16. The compression bandage combination of claim 10 , wherein the second compression bandage is applicable over the first compression bandage.
17. The compression bandage of claim 1 , wherein the first cushioning layer ( 1 ) is a wound contact layer.
18. A compression bandage consisting of a first cushioning layer ( 1 ) and a second supporting layer ( 2 ), wherein the first cushioning layer ( 1 ) and the second supporting layer ( 2 ) are connected to one another in the unstretched state via an elastic sewing thread by means of stitch-bonding where the stitch length is 1.5 to 3 mm at a sewing thread tension of not more than 4 cN, and wherein a material of the cushioning layer ( 1 ) and the supporting layer ( 2 ) is nonelastic and comprises a non-woven material; and wherein the compression bandage is only elasticized by means of stitch-bonding.
19. The compression bandage of claim 1 , wherein the first cushioning layer ( 1 ) and the second supporting layer ( 2 ) are in direct contact with each other.
