由任何加压包扎系统产生的绷带下压力在患者进行身体活动期间可能变化。了解小腿肌肉泵运动过程中绷带下压力的变化具有重要意义。本文旨在分析运动过程中绷带下压力的主导因素及其相互作用。在这项工作中，由于小腿肌肉泵的运动（扩张或收缩）的腿的周向变化模拟使用放置在人体模型上的气囊的扩张或收缩动作。这项研究已经进行了使用一个本土开发的原型泵或压缩空气的气囊使用气缸活塞安排。研究了一系列市售绷带，分析了气囊在一个膨胀或收缩周期中绷带伸展性（E）、绷带张力（T）和气囊膨胀或收缩量（A）等主要因素对绷带下压力的影响。选择了不同水平的因子，并准备了一个完整的析因设计，以获得在所有因素水平组合下的绷带下压力。结果表明，在动态模式下，短拉伸绷带的绷带下压力变化较大（p值< 0.05）。绷带下压力的变化通过增加气囊的膨胀或收缩量而增加，并且当绷带以更高的张力水平缠绕时也增加（p值< 0.05）。N-way ANOVA结果表明，上述因素（EA和AT）的一些交互作用也显著影响绷带下压力变化（p值< 0.05）。该原型提供了一种更简单的方法来评估在不同条件下的绷带行为，而无需进行体内绷带下的压力测量，因此可以用于评估和比较在不同条件下的不同压缩绷带的有效性，然后将其应用于受伤的腿上。(C)2012年组织活力协会。由爱思唯尔有限公司出版。保留所有权利。
The sub-bandage pressure produced by any compression bandaging system is likely to vary during the physical activities taken by the patient. It is of significant importance to understand the variation of sub-bandage pressure during the exercise of calf muscle pump. The present paper aims to analyse the dominating factors and their interactions on the sub-bandage pressure during exercise. In this work the circumferential change of the leg because of the exercise of the calf muscle pump (expansion or contraction) is simulated using expansion or contraction actions of an air bladder placed on a mannequin. The study has been carried out using an indigenously developed prototype by pumping or squeezing of air in air bladder using cylinder-piston arrangement. A series of commercially available bandages were studied and the impact of the major factors, namely bandage extensibility (E), bandage tension (T) and the amount of bladder expansion or contraction (A) on the sub-bandage pressure during one cycle of expansion or contraction of air bladder have been analysed. Different levels of the factors have been chosen and a complete factorial design was prepared to obtain the sub-bandage pressure at all combination of the levels of the factors. The results showed that the sub-bandage pressure variations were higher for short-stretch bandage under dynamic mode (p value < 0.05). The variation in sub-bandage pressure were increased by increasing the amount of expansion or contraction of the air bladder and also increased when the bandage was wrapped at higher tension level (p-value < 0.05). N-way ANOVA results showed that some of the interactions effects of these above factors (EA and AT) also significantly affecting the sub-bandage pressure variations (p-value < 0.05). The prototype provides a simpler method to assess the bandage behaviour under different conditions without doing in vivo sub-bandage pressure measurement, and hence could be used to evaluate and compare the effectiveness of different compression bandage under different conditions, prior to their application on the wounded leg.
