Description

Insoles provided for diabetic socks and a manufacturing method thereof {INSOLES PROVIDED IN DIABETIC SOCKS AND THEIR MANUFACTURING METHOD}

The present invention relates to an insole, and more particularly, to an insole provided in diabetic socks and a manufacturing method thereof.

If you suffer from diabetes, blood circulation is not smooth, your senses are dull, and your resistance to bacterial infection is reduced. Accordingly, even if a wound occurs in the body, pain is not felt well due to dulled senses, and even minor wounds progress rapidly due to low healing power and resistance to germs, causing serious complications such as ulcers and gangrene.

In particular, the feet are unavoidably subjected to weight and shock, and are likely to be neglected. Diabetic patients have dry feet and rough skin that is prone to cracks and injuries. In the case of a wound, it is difficult to detect the wound early because the senses are dulled due to neurological complications, and the bacterial resistance is weakened, so the wound is attached or complications caused by bacteria occur, and it is easy to develop into an ulcer.

Diabetic foot ulcers, also called diabetic foot ulcers, are collectively referred to as neuropathy, structural deformities, skin nails, skin and nail changes, foot ulcers, infections, and vascular diseases that occur in the feet of patients with diabetes. When diabetic foot progresses, even small wounds do not heal and become ulcers.

Therefore, it is a thin, soft cotton or wool blend material for diabetic patients who need to pay more attention to foot care. Socks (diabetic socks) are recommended. In addition, it is desirable for diabetic patients to wear diabetic socks even at home to protect their feet.

On the other hand, the “uneven physical external force” that is applied to the foot while wearing socks and puts a burden on it is the uneven pressure on the sole caused by the body weight (even when not wearing socks), the heel or toe tip between the skin and the sock. It can be divided into friction, friction and pressure by partially stitched lines (seam lines), and pressure on the band part that prevents socks from flowing down. The finely rough surface of the woven sock becomes a factor that increases the uneven external force acting on the sole of the foot where pressure is not applied and the tip of the toe or heel where friction occurs.

This non-uniform physical external force caused by wearing socks causes corns, warts, wounds, etc. even in normal people, but becomes a risk factor that can cause diabetic feet in diabetic patients.

Products related to diabetic socks are being developed to solve the above problems, but these socks minimize the pressure applied to the skin by the socks, prevent the socks from flowing down, easily absorb sweat, and have various characteristics related to the shape and physical properties of the pad part. It is only for reducing the impact during walking by walking, and it does not mention or suggest/teach any concepts or ideas about reducing the above-mentioned 'external force' for diabetic patients.

Hereinafter, an insole provided in a diabetic sock according to a preferred embodiment of the present invention will be described in detail with reference to the drawings. 1 is a perspective view of an insole provided in a diabetic sock. 2 is a plan view of an insole provided in a diabetic sock. FIG. 3 is a cross-sectional view A-A of FIG. 2 . 4 is a cross-sectional view of an insole provided in a diabetic sock. 5 is a conceptual diagram of distribution of an external force applied to a foot. Hereinafter, descriptions of conventionally known matters are omitted or simplified to clarify the gist of the present invention.

In addition, in the present invention, 'socks' is a concept that includes overshoes and overshoes as worn on the feet in addition to shoes. In addition, although the term 'diabetic socks' is used in the present invention, it does not exclude the use of ordinary people other than diabetic patients.

1 to 5, the insole 1 provided in the diabetic socks according to an embodiment of the present invention protects the user's feet and minimizes the uneven physical external force applied to the feet when the user lives indoors. can do. Here, users may include not only diabetic patients but also people who live and work indoors. The insole 1 provided in the diabetic socks may include a body 100, a pressure distributing unit 200, and wing units 300.

The body 100 is formed in an ergonomic shape so that the overall shape is the same or similar to that of a person's foot, so that the user's foot can be stably protected, and the body 100 is formed in the same or similar shape to the human foot, so that the contact area By maximizing this, it is possible to reduce the weight and pressure applied to the user's feet. In addition, the main body 100 may be provided with an arch portion 110 capable of supporting the arch portion of the user's foot, and thus, a space is eliminated between the user's foot and the main body 100 to distribute weight and pressure. It can be easy. In addition, the main body 100 may be provided with a pressure distribution unit 200 on one surface, and may be provided with a wing unit 300 at an edge.

In addition, the main body 100 may be formed of OrthoLite material, which has excellent air permeability, excellent resilience and shock absorption, and suppresses odor. OrthoLite has excellent adhesiveness and can prevent a hydrolysis phenomenon in which the main body 100 and the fabric 120 laminated on one surface of the main body 100 are decomposed by water. Accordingly, the insole 1 provided in the diabetic socks can be washed with water without considering the decomposition of the main body 100 and the fabric 120 by water. Although the material of the main body 100 in the present invention has been described as an example of OrthoLite, the material of the main body 100 of the present invention is not limited to OrthoLite, and the same or similar functions can be performed. If available, it can be substituted.

Here, the whole or part of the fabric 120 laminated on the surface of the main body 100 may be formed of an antibacterial material. For example, it may be formed by laminating a semi-permanently antibacterial fabric on the surface of the main body 100 instead of a general fabric, or by using antibacterial yarn on a toe area with a high possibility of infection.

In addition, the adhesive means used to laminate the fabric 120 on the main body 1 may be at least one or a mixture of one or more of a film form, a liquid form, a water-based adhesive, and a hot melt adhesive. The bonding means permeates through air holes, which are characteristics of OrthoLite forming the main body 100, and can bond the main body 1 and the fabric 120 with stronger adhesive strength.

The pressure distribution unit 200 may be provided on one surface of the body 100 and may be provided at a predetermined height. In the present invention, the position of the pressure distributing unit 200 is not limited, but as shown in FIG. 5, it is preferable to be provided at a position corresponding to the metatarsal bone where the most weight and pressure are applied. Accordingly, the weight and pressure applied to the user's foot, that is, "uneven physical external force" can be evenly distributed and minimized, and impact can be minimized.

In addition, the pressure distribution unit 200 may be formed in a transverse direction and may be formed in a preset width and length. Both side ends of the pressure distributing unit 200 may be formed such that a distance from the wing unit 300 is equal to or less than a predetermined reference distance (eg, 5 mm). That is, the pressure distributing unit 200 may be formed with a width larger than that of the metatarsal bone of the insole wearer. The pressure distributing unit 200 may be formed with a sufficient width to correspond to the metatarsals of various insole wearers. Accordingly, it is applicable to various foot sizes of users.

In addition, the pressure distributing unit 200 may be formed of the same OrthoLite material as the main body 100 . However, like the main body 100, the material is not limited to OrthoLite, and any material that can perform the same or similar function can be substituted.

The wing portion 300 may be formed to be bent from the edge of the body 100 in the direction of one surface to extend by a predetermined height, and may be formed in a shape that gradually becomes thinner as it extends from the edge of the body 100 in the direction of one surface. can Accordingly, the end of the fabric 120 laminated on one surface of the main body 100 and the elastic end of the wing portion 300 can be bonded more firmly. At this time, the height of the wings 300 may be extended to a constant height as a whole, but may be extended to a different height depending on the position, and the height may vary only in one section.

In addition, the wing portion 300 is formed to extend by a predetermined height to wrap around the outer circumference of the user's sole, thereby minimizing friction between the user's foot and the inner surface of the sock and absorbing shock such as colliding with an external object. can be done

In addition, the wing portion 300 may have a curved portion 310 formed in a round shape, and the curved portion 310 is laminated on one surface of the outer curved portion 311 bonded to the inside of the sock 400 and the main body 100. It may include internal bends 312 to which the fabric is bonded. At this time, the outer curve 311 and the inner curve 312 are formed in a round shape, so that the outer curve 311 and the socks 400 and the inner curve 312 and the fabric 120 are bonded to each other. adhesive strength can be maximized. And, by making the thickness of the wing part 300 thin as it goes from the bottom to the top, the wing part 300 can be easily bent inward and outward. Accordingly, even if an external force is applied to the wing 300 or the sock 400 after wearing the insole, the sock 400 attached to the outer curve 311 of the wing 300 may not be easily separated from the wing 300. there is.

In addition, the round shape of the inner curve 312 is also applied to the heel portion of the user's foot, so that the user's heel is also in close contact with the main body 100 and the wing portion 300 to remove foreign body sensation during use.
