Anti-embolism stockings, the similarities and differences

The medical textiles sector is growing annually, estimated to reach $2.7 billion by 2018. Predominantly attributed to the growing and ageing population, and consequently there has been a vast increase in venous disorders. Currently 61% of the British population are thought to be at risk of deep vein thrombosis (DVT), of which the majority is avoidable given the correct prophylaxis. Anti-embolism stockings (AES) are used to prevent DVT when hospitalised patients are supine for long periods of time. The market place is competitive, with numerous brands striving to win the local British National Health Service contract. It is a commodity market, with low profit margins but high volumes. The aim of this research was to seek an understanding of the AES on the market, exploring the different construction techniques, knit notations and yarn characteristics in three popular AES brands, with the overall aim of providing a basis of knowledge to improve product development, product efficacy and ultimately save lives.
