Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of insoles for relieving and preventing varicose veins in the lower limbs, and more specifically, it relates to an insole for relieving and preventing varicose veins in the lower limbs. Background Technology
[0002] Varicose veins in the lower extremities are a common condition among people who stand for long periods. It is prevalent among teachers, surgeons, chefs, hairdressers, nurses, baristas, bartenders, flight attendants, assembly line workers, laboratory technicians, sales clerks, traffic police, and other professions that require prolonged standing. The incidence rate of varicose veins in my country is 10%, reaching as high as 20-30% in some high-risk occupational groups. There are two main causes of varicose veins: genetics and occupational environment. In some people who stand for long periods, the lack of exercise weakens blood return, and the valves in the blood vessels become lax due to the prolonged impact of gravity causing blood to flow backward, leading to embolism. On the other hand, the bone structure of the feet deforms under the influence of gravity in people who stand for long periods, causing compression (narrowing) of blood vessels, narrowing the blood flow, and making it impossible to prevent backflow, thus leading to embolism.
[0003] Based on the above, the inventors have discovered the following problem: existing insoles have only one function and do not have the effect of relieving or preventing varicose veins in the lower limbs.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide an insole that can alleviate and prevent varicose veins in the lower limbs, in order to achieve a more practical purpose. Utility Model Content
[0005] The purpose and effect of this utility model of an insole for relieving and preventing varicose veins in the lower limbs are achieved by the following specific technical means:
[0006] An insole for relieving and preventing varicose veins in the lower extremities includes an insole body. The insole body is composed of a medial longitudinal arch support module, a lateral longitudinal arch support module, a forefoot transverse arch support module, a toe support module, a heel cup-shaped module, a connecting module, and a heel support pad. The toe support module has a connecting module on one side, the connecting module has a forefoot transverse arch support module on one side, and the forefoot transverse arch support module has a heel support pad on the side away from the connecting module. The heel support pad has a medial longitudinal arch support module and a lateral longitudinal arch support module on both sides, and the heel support pad has a heel cup-shaped module on the side away from the forefoot transverse arch support module.
[0007] Furthermore, the longitudinal height of the forefoot transverse arch support module is 12mm.
[0008] Furthermore, the height of the apex of the inner longitudinal arch support module is 40mm.
[0009] Furthermore, the height of the apex of the outer longitudinal arch support module is 30mm.
[0010] Furthermore, the longitudinal height of the cup-shaped heel module is 26mm.
[0011] Furthermore, the vertical height of the connecting module, toe support module, and heel support pad is 2mm.
[0012] Furthermore, the inner longitudinal arch support module, the outer longitudinal arch support module, the forefoot transverse arch support module, the toe support module, the heel cup-shaped module, the connecting module, and the heel support pad are all made of high-polymer elastic material.
[0013] Furthermore, an anti-slip layer is provided on the underside of the insole body.
[0014] Furthermore, the toe support module, the connecting module, and the heel support pad are provided with massage protrusions.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] In this invention, the design of the medial longitudinal arch support module, which supports the medial longitudinal arch, can alleviate the compression of the posterior tibial aorta and medial plantar arteries caused by the sinking of the navicular bone in flat feet. This maintains the normal geometric shape of the blood vessel walls and ensures smooth blood return.
[0017] The design of the lateral longitudinal arch support module is designed to support the lateral longitudinal arch, which can relieve pressure on the fifth metatarsal tuberosity and prevent compression of the lateral plantar artery.
[0018] The design of the forefoot transverse arch support module is used to support the transverse arch of the foot, which can relieve the compression of the anterior arch artery and the common anterior digital artery by the first to fifth metatarsal bones.
[0019] The design of the toe support module is designed to support the toe joints and can relieve the compression of the proper arteries of the toes by the second to fifth metatarsal bones.
[0020] The design of the heel cup module supports the calcaneus, preventing abnormal force lines caused by calcaneal eversion (leading to flat feet) and relieving vascular pressure on the posterior tibial aorta and medial artery.
[0021] The design incorporates high-polymer elastic material in the medial longitudinal arch support module, lateral longitudinal arch support module, forefoot transverse arch support module, toe support module, heel cup-shaped module, connecting module, and heel support pad. The rebound coefficient of the high-polymer elastic material is between -% and -%. This rebound index can generate a strong pumping effect on blood vessels, thereby generating centripetal return force on blood vessels and thus relieving varicose veins in the user's lower limbs.
[0022] The design incorporates an anti-slip layer at the bottom of the insole to prevent slippage and misalignment between the insole and the sole, thus ensuring a better user experience.
[0023] The design incorporates massage protrusions on the toe support module, connecting module, and heel support pad, which can massage the user's soles and relieve foot fatigue while walking. Attached Figure Description
