Electronic muscle stimulator to prevent thrombosis - promotes return circulation of blood by causing contractions of muscular sheath of veins

摘要

The electronic stimulation is programmed to operate automatically and is designed to prevent the occurrence of embolisms in hospital patients. It achieves this by preventing stagnation of blood in the veins by increasing the tone of the muscles surrounding the veins. This has the effect of massaging the veins and assisting the return arcuation of the blood veins themselves is promoted.
