Compression Sleeves Design Based on Laplace Laws

Abstract

Compression sleeves are very important to the prevention and control of human limb hyperplasia scaring. The garment pressure is the key determinant of the curative effect, and one of the key factors which influence this value is the precision of Compression sleeves design. In order to study the design and performance of Compression sleeves via relatively simple but accurate methodologies, different deformation formulas of Laplace law were summarized and analyzed. Firstly, it was found that both of the deformation formulas of Laplace law proposed by Maklewska and Leung respectively were based on the principle that the arm radius was calculated by the arm circumference, furthermore, the arm radius, fabric tensile index and the preset clothing pressure were substituted into the Laplace law formula, and the sizes of the Compression sleeves could be calculated. Since the design methods proposed above were easier to implement in practical production, Compression sleeves were designed and manufactured based on the deformation formulas of Laplace law, and garment pressures were tested and compared with the preset pressures. Experimental results showed that garment pressures of the Compression sleeves which were designed based on the Maklewska Laplace law within the scope of the required pressure value, so this deformation could be used for designing the Compression sleeves accurately. However, the sizes of the Compression sleeves which were calculated based on the Leung Laplace law were too small to put on, so the formula of Leung Laplace law was not suitable for designing the Compression sleeves.
