① The present invention combines mechanical pressure with electrical stimulation of acupoints to complement each other. At present, the products on the market are all single-function products. This design organically combines two treatment methods with different mechanisms of action, which can complement each other, and the expected effect is better.

②The product design is more in line with the principle of bionics. The gastrocnemius muscle pump mainly promotes the venous return of the lower extremities. Therefore, when the lower limbs of the human body move normally, the gastrocnemius muscle pump plays a role, and there will be no blood stasis and thrombosis. According to the contraction and relaxation rules of the gastrocnemius pump muscle group during ordinary people's activities, acupoints and electrical stimulation parameters are selected, which is in line with the principle of bionics.

③The product is small in size, easy to operate, easy to carry and use. Products currently on the market are either bulky or cumbersome to operate. Even in the professional departments of the hospital, the unreasonable frequency of use affects the therapeutic effect, making non-drug therapy fail to fully exert its therapeutic effect. This product design can make up for the above shortcomings, making non-drug therapy effective in preventing lower extremity venous thrombosis. Get down to it.
