Description

Pumping slipper for promoting blood circulation {Pumping slipper for promoting blood circulation}

The present invention relates to a pumping slipper capable of stimulating blood circulation.

The feet are the lowest part of the body that supports a person's weight, and when blood circulation is impaired in the feet, swelling of the feet and legs occurs. Many people have swelling in their feet and legs when they sit or stand all day due to school work or work. When the blood delivered from the heart to the capillaries of the legs through the arteries returns to the heart, it can return only by minute movements of the leg muscles. It cannot move smoothly, resulting in numbness and swelling in the legs. The phenomenon of numbness in the legs due to varicose veins in the calf is also the same reason.

Since the feet are an important part of the body as they are called the second heart, there are various shoes on the market that help blood circulation in the feet for these people.

Types of slippers that help blood circulation include slippers having an acupressure function, such as the Korean Patent Registration (20-0197545), and low-frequency slippers, such as the Korean Patent Registration (20-0411485).

An object of the present invention is to provide a shoe that provides a slipper mode/blood circulation promoting exercise mode to promote blood circulation.

Blood pressure is the force of blood flow per unit area of blood vessels. Blood flow velocity is proportional to blood pressure and inversely proportional to flow resistance. Here, the flow resistance of the blood vessel is proportional to the length of the blood vessel and inversely proportional to the cross-sectional area. When the blood vessel is viewed as a constant, blood pressure must be increased to increase the blood flow rate. Therefore, it is necessary to move the leg muscles to increase the blood pressure in the legs, and as a result, blood circulation can be promoted by increasing the blood flow rate.
