Description

Pressure-adjustable lower limb elastic bandage for improving venous reflux

Technical Field

The utility model belongs to the technical field of varicosity apparatus, concretely relates to a low limbs elastic bandage with adjustable a pressure for improving venous return.

Background

Varicose veins of lower limbs are long-term compression of venous vessels of the lower limbs by abnormal blood flow, so that normal functions of valve membranes in the vessels are damaged, excessive blood is accumulated in the vessels, the vessel walls are thinned and the vessels are protruded, blood stasis occurs over time, and thrombus, skin trophism change and ulcer formation are complicated. It is often seen in patients who are permanently standing or heavy physical workers and patients with vascular valve damage caused by deep vein thrombosis of the lower limbs. The lower limb venous blood reflux is promoted, so that the development of varicosity can be delayed, the occurrence of related complications is reduced, and the life quality of patients is improved.

Pressure treatment may improve venous return. Continued pressure applied to the vein may reduce the vessel diameter and reduce the transmural pressure, which may increase the flow rate by a factor of about 2. In the recumbent position, a pressure of 15mmHg is sufficient to restrict superficial and deep veins, improving and accelerating blood flow; when the human body is upright, the same effect can be achieved only by applying pressure as high as 60-90 mmHg. Under physiological conditions, the pressure of the ankle is highest in the lower limb, the pressure of the next knee is lowest, and the pressure of the thigh is lowest. When pressure treatment is carried out, pressure is applied in a segmented mode, the highest supporting pressure is built at the ankle part, and the pressure gradually decreases upwards.
