Abstract
Compression bandage (CB) as a porous material consists of elastic textile that exerts pressure on muscles. Three common types of woven CBs are evaluated. Uniaxial stresses of the input yarns and the produced bandage will be tested. This work presents a new method to predict optimum required tension when applying CB on lower leg ankle and mid-calf positions. Experimental measurements and data analysis using NIS software enable to analyze and calculate the bandage porosity during extension using high speed camera. Practical bandage pressure is measured using PicoPress tester. The obtained results will be compared with theoretical compression forces calculated by a modified Laplace's law equation which predicts graduated compression ranging from 27 to 72 mmHg at the ankle, tapering to 18-8 mmHg below the knee. Results confirm that theoretical pressure is not exactly consistent with practical compression.
