Description

Technical Field

[0001] The utility model relates to the technical field of insoles, in particular to an insole for improving varicose veins of lower limbs. Background Art

[0002] Varicose veins in the lower limbs are a common disease among people who stand for a long time. There are two causes of varicose veins in the lower limbs: one is genetic, and the other is caused by the occupational environment. In some people who stand for a long time, the lack of exercise weakens the blood flow back, and the blood vessel valves are impacted by the gravity backflow of blood for a long time, causing relaxation, which leads to embolism. On the other hand, the bone structure of the soles of people who stand for a long time deforms under the action of gravity, resulting in compression (narrowing) of the blood vessels, thinning of the blood return, and failure to prevent the backflow of blood, which leads to embolism.

[0003] The Chinese patent publication number CN215775925U discloses a special insole for teachers and people who stand for a long time. The arch support and protection pad is arranged below the insole body, and is used to support and protect the position of the arch of the human foot. It can provide good support and protection for the foot, provide mechanical control during long-term standing, relieve the pressure on the leg, thereby protecting the foot and calf muscles, and preventing muscle contraction from affecting the centripetal flow of venous blood, thereby causing varicose veins in the lower limbs, etc. The first support and protection pad and the second support and protection pad are arranged on the inner and outer sides below the arch support and protection pad, which can support and protect the foot, balance and stabilize the foot, relieve the pressure on the foot, prevent the foot from tilting, stabilize the center of gravity, balance the body, make the foot evenly stressed, and avoid causing great pressure on the local position of the legs due to unstable center of gravity, thereby affecting the centripetal flow of venous blood.

[0004] Existing insoles use a variety of complex support structures to support the soles of the feet, but do not make different response plans based on the distribution of blood vessels in the soles of the feet. The improvement effect is insufficient, and many blood vessels are still easily squeezed. Utility Model Content

[0005] In view of the above problems, the utility model aims to solve the above problems. One purpose of the utility model is to provide an insole for improving varicose veins of the lower limbs to solve the above problems, improve the support position and height of the sole, improve the compression of blood vessels, ensure blood circulation, and effectively prevent the occurrence of varicose veins of the lower limbs.

[0006] The solution adopted in this embodiment is as follows: An insole for improving varicose veins of the lower extremities, including a transverse arch support part of the forefoot located at the arch position and a toe support part located at the toe position. The height of the raised part of the transverse arch support part of the forefoot is greater than that of the toe support part, and the height of the transverse arch support part of the forefoot gradually decreases along the direction close to the toe support part; A suspended part is formed between the transverse arch support part of the forefoot and the toe support part, and the suspended part is located at the metatarsal position of the sole. It effectively relieves the extrusion of a large number of blood vessels at the metatarsal position by the insole and effectively prevents the occurrence of varicose veins of the lower extremities.

[0007] Specifically, for the toe support part, the toe support part extends from the little toe to the position of the second toe, and the length of the toe support part is getting longer and longer. The length of the front end of the toe support part extends to the end of the insole, and the length of the rear end of the toe support part extends to the connection between the phalanx and the metatarsal bone. The suspended part extends to the position of the big toe.

[0008] Further, along the length direction of the insole, a protruding part is formed by the middle area of the transverse arch support part of the forefoot protruding towards the toe direction. The protruding part is arc-shaped, and both sides of the protruding part contract away from the toe direction.

[0009] For effective support, the preferred size selection is that the raised height of the toe support part is 2 - 5 mm, the maximum raised height of the transverse arch support part of the forefoot is 20 - 30 mm, and the spacing of the suspended part is 12 - 50 mm.

[0010] For better support of the inner side of the sole, it also includes a medial longitudinal arch support part located on the inner side of the sole. The medial longitudinal arch support part is connected to the transverse arch support part of the forefoot. The height of the medial longitudinal arch support part is greater than that of the transverse arch support part of the forefoot, and the medial longitudinal arch support part protrudes towards the arch direction.

[0011] Among them, the preferred solution is that the medial longitudinal arch support part raises the side edge of the transverse arch support part of the forefoot. The height of the highest point of the medial longitudinal arch support part is 35 - 45 mm, and the front end of the medial longitudinal arch support part extends to be flush with the front end of the transverse arch support part of the forefoot.

[0012] For better support of the outer side of the sole, it also includes a lateral longitudinal arch support part located on the outer side of the sole. The lateral longitudinal arch support part is located in the middle of the insole. The front end of the lateral longitudinal arch support part extends to be connected with the transverse arch support part of the forefoot as a whole. The lateral longitudinal arch support part raises the side edge of the transverse arch support part of the forefoot, and the raised height of the lateral longitudinal arch support part is less than the raised height of the medial longitudinal arch support part.

[0013] Further, both the outer longitudinal arch support part and the inner longitudinal arch support part bulge inward at the intersection of the rear sole and the arch, and this position is the highest point of the outer longitudinal arch support part and the inner longitudinal arch support part. The distance from the highest point of the outer longitudinal arch support part to the rearmost end of the insole is 50 - 60 mm, and the distance from the highest point of the inner longitudinal arch support part to the rearmost end of the insole is 100 - 120 mm.

[0014] In order to reduce the extrusion of blood vessels in the rear part of the sole, a concave part is formed by the downward depression between the outer longitudinal arch support part and the inner longitudinal arch support part.

[0015] Preferably, it further includes a heel cup-shaped part arranged around the rear sole. The middle part of the cup-shaped part is depressed downward to form a rear sole support part. The rear sole support part is integrally connected with the concave part, and the distance between the highest point of the cup-shaped part and the lowest point of the rear sole support part is 20 - 35 mm.

[0016] The insole of the present utility model for improving varicose veins of the lower extremities has the following technical effects:

[0017] The insole of the present application for improving varicose veins of the lower extremities includes a front sole transverse arch support part located at the arch position and a toe support part located at the toe position. The height of the convex front sole transverse arch support part is greater than that of the toe support part, and the height of the front sole transverse arch support part gradually decreases along the direction close to the toe support part; a suspended part is formed between the front sole transverse arch support part and the toe support part. The suspended part is located at the metatarsal position of the sole, and a large number of blood vessels are concentrated in the front sole. The suspended part enables a large number of blood vessels not to be extruded, effectively relieving the extrusion of a large number of blood vessels in the metatarsal position by the insole and effectively preventing the occurrence of varicose veins of the lower extremities.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. It should be noted that, without conflict, the embodiments in this application and the features in the embodiments may be combined with each other arbitrarily.

[0025] The following will, with reference to the accompanying drawings and embodiments, elaborate on the insole for improving varicose veins of the lower extremities in detail.

[0026] As Figure 1 、 Figure 2 shown, an insole provided by the present utility model for improving varicose veins of the lower extremities is integrally formed of a polymer elastic material, and a circulating driving force is generated on the blood through the compression and rebound performance of the material. Its elastic expansion and contraction function can cause a pumping effect on blood vessels. Consequently, a centripetal pressure is generated on the blood, enhancing the blood return power of blood vessels. It can enable blood vessels with poor blood flow to restore blood supply capacity.

[0027] The specific components of the insole include the transverse metatarsal arch support part 3 at the arch of the foot and the toe support part 1 at the toe position. The height of the convex part of the transverse metatarsal arch support part 3 is greater than that of the toe support part 1, and the height of the transverse metatarsal arch support part 3 gradually decreases along the direction close to the toe support part 1. Supporting the sole of the foot from the arch of the foot, the gradually decreasing height allows this area of the sole of the foot to gradually hang in the air, thereby reducing the extrusion of blood vessels. It mainly has a great alleviating effect on the extrusion of the first to fifth metatarsal bones on the plantar arterial arch and the common plantar digital arteries. A suspension part 2 is formed between the transverse metatarsal arch support part 3 and the toe support part 1, and the suspension part 2 is located at the metatarsal position of the sole of the foot. It effectively alleviates the extrusion of a large number of blood vessels at the metatarsal position by the insole and effectively prevents the occurrence of varicose veins in the lower extremities. There are a large number of blood vessels near the metatarsal position, and the common plantar digital arteries are distributed in this area, and this position is under long-term stress when the human body stands. The toe support part 1 lifts and supports the four toes, giving a support point to the front end of the sole of the foot, so that the extrusion force on the sole of the foot at the position of the suspension part 2 is effectively reduced, and at the same time, it can relieve the extrusion of the second to fifth phalanges on the proper plantar digital arteries.

[0028] Specifically, for the toe support part 1, the toe support part 1 extends from the little toe to the position of the second toe, and the length of the toe support part 1 is getting longer and longer. The length of the front end of the toe support part 1 extends to the end of the insole, and the length of the rear end of the toe support part 1 extends to the connection between the phalanx and the metatarsal bone. The suspension part 2 extends to the position of the big toe. The toe support part 1 is designed to adapt to the different lengths of the four toes, and the length is the shortest at the position of the little toe. There is no toe support part 1 aligned to support in the area of the big toe. When standing, the area where the thumb is located is under greater force, so the sinking height also needs to be greater, so that the extrusion force on the thumb by the insole is reduced.

[0029] Further, along the length direction of the insole, a protruding part 31 is formed by the middle area of the transverse metatarsal arch support part 3 protruding towards the toe direction. The protruding part 31 is arc-shaped, and both sides of the protruding part 31 contract away from the toe direction. The middle position of the transverse metatarsal arch support part 3 is relatively prominent, adapting to the distribution of the bones on the sole of the foot and effectively providing uniform support for the sole of the foot. For effective support, the preferred size selection is that the convex height of the toe support part 1 is 2 - 5 mm, and 3 mm is preferably used in this embodiment. The maximum convex height of the transverse metatarsal arch support part 3 is 20 - 30 mm, and 20 mm is preferably used in this embodiment. The spacing of the suspension part 2 is 12 - 50 mm. In this embodiment, the gap at the little toe position is preferably 12 mm, and the spacing at the big toe position is 50 mm. The above dimensions and other dimensions of this insole can be adaptively modified according to different foot shapes and sizes after scanning the foot pressure with a plantar pressure detection device.

[0030] For better support of the inner side of the sole, it further includes a medial longitudinal arch support part 5 located on the inner side of the sole. The medial longitudinal arch support part 5 is connected to the transverse metatarsal arch support part 3. The height of the medial longitudinal arch support part 5 is greater than that of the transverse metatarsal arch support part 3, and the medial longitudinal arch support part 5 protrudes towards the arch of the foot. It supports the medial longitudinal arch and relieves the compression of the posterior tibial aorta and the medial plantar artery vessels caused by the sinking of the navicular bone and flat feet. It keeps the blood vessel wall in a normal geometric shape and ensures smooth blood return. Preferably, the medial longitudinal arch support part 5 raises the modified side edge of the transverse metatarsal arch support part 3. The height of the highest point of the medial longitudinal arch support part 5 is 35 - 45 mm, and the preferred height is 40 mm. The front end of the medial longitudinal arch support part 5 extends to be flush with the front end of the transverse metatarsal arch support part 3. The medial longitudinal arch support part 5 raises the middle position on the inner side of the insole and supports the arch of the foot from the inner side.

[0031] For better support of the outer side of the sole, it further includes a lateral longitudinal arch support part 4 located on the outer side of the sole. The lateral longitudinal arch support part 4 is located in the middle of the insole. The front end of the lateral longitudinal arch support part 4 extends to be connected with the transverse metatarsal arch support part 3 as a whole. The lateral longitudinal arch support part 4 raises the modified side edge of the transverse metatarsal arch support part 3. The raising height of the lateral longitudinal arch support part 4 is less than the raising height of the medial longitudinal arch support part 5. The lateral longitudinal arch support part 4 supports the lateral longitudinal arch, relieves the pressure at the tuberosity of the fifth metatarsal bone, and prevents the compression of the lateral plantar artery vessels.

[0032] Furthermore, both the lateral longitudinal arch support part 4 and the medial longitudinal arch support part 5 protrude towards the inner side at the intersection of the rear part of the sole and the arch of the foot. This position is the highest point of the lateral longitudinal arch support part 4 and the medial longitudinal arch support part 5. The distance from the highest point of the lateral longitudinal arch support part 4 to the rearmost end of the insole is 50 - 60 mm, preferably 55 mm. The distance from the highest point of the medial longitudinal arch support part 5 to the rearmost end of the insole is 100 - 120 mm, preferably 110 mm. The lateral longitudinal arch support part 4 and the medial longitudinal arch support part 5 limit both sides of the sole, and at the same time, the inner protruding positions of the two support the bones. To reduce the compression of the blood vessels in the rear part area of the sole, a concave part 9 is formed by the depression between the lateral longitudinal arch support part 4 and the medial longitudinal arch support part 5. The concave part 9 makes the blood vessels slightly suspended, so that the blood vessels at this position are not easily compressed.

[0033] Preferably, it further includes a heel cup portion 6 disposed around the rear foot sole. A rear foot sole support portion 8 is formed by downward depression in the middle of the cup portion. The rear foot sole support portion 8 is integrally connected to the concave portion 9. The distance between the highest point of the cup portion and the lowest point of the rear foot sole support portion 8 is 20 - 35 mm, and the preferred distance is 30 mm. The sunken rear foot sole support portion 8 is provided at the rear foot sole position, so as to support the foot sole in cooperation with the transverse arch support portion 3 of the front foot. The heel cup portion 6 supports the calcaneus, prevents the abnormal force line caused by calcaneal valgus (resulting in valgus flat foot), and relieves the vascular pressure of the posterior tibial artery and the medial artery.
