不同压力等级医疗袜下腿部共偶变形分析

为探究不同压力等级下医疗袜对腿部共偶变形的影响,测量不同压力等级医疗袜的多个姿势中腿部各截面的共偶变形。结果表明:相比较1级压力医疗袜,2级和3级压力医疗袜对中腿部分的共偶变形作用大;在足底用力的情况下(微蹲、自然站立、踮脚站立),足与小腿间的角度为90°时,踝骨围最大;双脚均着地(自然站立、微蹲、正坐)时,膝围大小与大腿和小腿夹角呈负相关,夹角越小,膝围越大。研究结果可为产品设计师和医师在开发和临床应用医疗袜方面提供参考。     

A New Measurement System for Static and Dynamic Clothing Pressure

This study aims to develop a system and measurement method for investigating the static and dynamic pressure behavior of compression products.The self-designed measurement system,named "cloth-press" ( LLY-56B).is a direct measurement method,which is based on a rigid hemisphere with three pressure sensors distributed on its surface.The static pressure is measured at predetermined press depth,and the dynamic pressure is measured under the processing of fabric 3D deformation.The pressure distributions at the basic three sites are accepted as the measurement results.The measurement results provide much information in the field of compression fabric assesment,and the measurement system can be used in scientic research institutes and factories,contributing to optimize process parameters and quality control of compression garment.
