Compression hosiery is used in the management of a large number of medical conditionsaffecting the venous and lymphatic systems. The appropriate product type, pressureclassification, and design are dependent upon the specific application. Graduatedcompression hosiery is used to improve venous and lymph flow in conditions such as ofvaricose veins, venous leg ulcers, post-operative deep vein thrombosis, and oedema.Venous ulcers are the most frequently occurring type of chronic wound affecting 1-2% of theUK population at any one time. This has a significant impact on healthcare costs anddrastically affects the quality of life of those afflicted with this condition. It is difficult toaccurately assess the cost for the treatment of all of these conditions with compressiontherapies. However, a good indication of the scale of the cost is given by the £800m perannum it is estimated to cost the NHS for the treatment of venous leg ulcers.The cost-effective management of these medical conditions depends upon understanding andknowledge of the behaviour of the bandaging system when deployed upon the leg of thepatient. Currently this understanding is based upon the classification of the bandage and thepressure that it is designed to apply to a limb. As matters stand, hosiery is classified into arange of pressure gradients defined by British Standard 6612: 1985. This Standard is basedupon tests performed employing experimental apparatus known as the HATRA PressureTester. However, there are significant limitations to the capabilities of the HATRA testingequipment.The invention of pressure sensors that are formed by a new, printable, ink-based technologyhas made it possible to create a testing apparatus that is far closer to a simulacrum of thehuman leg. It is proposed that such a device will allow the laboratory testing of compressionstockings and bandages that accurately reflects their behaviour when applied to patients.

压力袜用于治疗影响静脉和淋巴系统的大量医疗状况。适当的产品类型、压力分类和设计取决于具体应用。分级压缩袜用于改善静脉曲张、腿部静脉溃疡、术后深静脉血栓和水肿等情况下的静脉和淋巴液流动。静脉溃疡是最常发生的慢性伤口类型，曾影响过 1-2% 的英国人口。这对医疗费用产生重大影响，并极大地影响患有这种疾病的人的生活质量。很难准确评估通过加压疗法治疗所有这些病症的费用。然而，NHS 每年用于治疗腿部静脉溃疡的费用估计为 8 亿英镑，这很好地说明了费用的规模。这些医疗状况的成本效益管理取决于对绷带系统在患者腿部部署时的行为的理解和了解。目前，这种理解基于绷带的分类及其设计用于施加到肢体的压力。就目前情况而言，袜子被分为英国标准 6612: 1985 定义的一系列压力梯度。该标准基于使用称为 HATRA 压力测试仪的实验设备进行的测试。然而，HATRA 测试设备的功能存在很大的局限性。采用新型可印刷墨水技术形成的压力传感器的发明，使得创建更接近人类腿部模拟物的测试设备成为可能。据建议，这种设备将允许对压力袜和绷带进行实验室测试，准确反映它们应用于患者时的行为。
