The Effect of Structural Parameter on Pressure Behaviour of Tubular Bandage

Compression therapy is the most widely used treatment for venous leg ulcer (VLU), and it has been utilised in different forms for more than four centuries. There are wide varieties of compression bandages available for the treatment of various diseases. A suitable regime has to be selected for the specific problem based on required pressure level. In this paper, a study was conducted on the pressure behaviour of single jersey tubular bandage by varying the Lycra Denier (20, 30, 40 denier), stitch length (mm) in the structure at different limbs circumference (20, 30, 33 cm) on an artificial limb layered with foam of different hardness (10, 20 and 30). The effect of parameters both individually and interactively on the pressure performance of tubular bandage was statistically analysed. As compared to other constructional parameters, stretch (%) of tubular bandage has the most significant impact in generating required bandage pressure. From ANOVA analysis it is concluded that stretch (%) has almost 40% contribution in imparting overall bandage pressure whereas stitch length, lycra denier and limb hardness has 20%, 20% and 16% contribution respectively.
