Abstract

The invention discloses an intelligent compression system made by a shape memory material. The intelligent compression system is used for managing or preventing chronic venous insufficiency and comprises a shape memory module, an excitation module for exciting shape memory effect and a control module receiving information fed back by the shape memory module and controlling excitation process. The shape memory module comprises but not limited to textiles, made by the shape memory material and with a certain function structure, like compressed stockings and compressed bandages. The invention further relates to making of shape memory filaments and shape memory modules different in structure. The intelligent compression system has the advantages that pressure applied on damaged limbs by the shape memory module can be changed and controlled through simple excitation modules, and the defect of pressure lowering of the shape memory module along with time increase can be overcome, so that treatment degree of freedom is increased, treatment effect is improved, and treatment cost is lowered.

Description

technical field [0001] The present invention relates to the field of medical devices, in particular to a compression system based on shape memory materials for managing or preventing chronic venous insufficiency. Background technique [0002] Chronic venous insufficiency seriously affects the quality of life of patients due to persistent pain and discomfort, restricted mobility, long recovery time, high treatment cost, and harsh treatment methods. Chronic venous insufficiency of the lower extremities is a clinical syndrome caused by peripheral venous insufficiency of blood return to the heart, including varicose veins of the lower extremities, primary deep venous valve insufficiency, and deep venous thrombosis of the lower extremities. Compression therapy has been a must for patients battling ailments since ancient times. The external pressure applied to the damaged limb can accelerate the return of venous blood, thereby reducing the venous blood pressure, so as to achieve ...
