"¾ Regarding the method.

(Background technology)

Covering equipment that covers an urban area of rest and secures, supports, compresses, protects, keeps warm, and corrects that part is a shoulder for medical and sports use. , Elbows, hands, hips, knees, feet, etc., joints used in the city, chest, abdomen, hips, forearms, upper arms, thighs, lower legs, etc. Various types are known in terms of form, structure, and material from the viewpoint of operability and operability. First of all, the morphological aspects are roughly divided into lollipops and cylindrical ones. As for the structural aspect, the thick body covering the affected area Rigid, non-stretch, stretchable material to partially secure, support, compress, protect, heat, or correct the body-covered city Materials with different genders, materials with different cushioning characteristics, materials with different thicknesses, etc. are combined, and a belt etc. of the main body is added. In terms of materials, in addition to the materials with the above-mentioned properties, there are materials with air permeability and materials with high hygroscopicity. These are simple or composite materials such as woven fabric, knitted fabric, nonwoven fabric, plastic, and rubber foam. Consists of materials.

These S-braces have high fitness, good operability, good wearing feeling, and can be fixed, supported, pressed, protected, kept warm, or corrected only at the required location. Although it is necessary, various devises have been made since the human body has a different body shape and is not a planar structure. For example, in order to improve the fitting property, the attachment method is a binding method, the auxiliary belt is attached to the brace, and the system is tightened again from the brace, the three-dimensional structure is incorporated into the brace design, and the directionality of the material is adopted. In view of the above, we use techniques for draping and sewing, and combine materials with various characteristics from the material side. Further, in order to improve operability, in the mounting method, the knitting method is changed to a touch method using a hook-and-loop fastener, and the band method is changed to a cylindrical method. In addition, fixing only the necessary parts, supporting, pressing, protecting, keeping warm, correcting, etc. For this purpose, three-dimensional sewing technology has been used,-. Auxiliary belts have been installed-Thick materials have been used, pad materials have been added, and various materials have been combined. I have.

However, conventional covering devices do not always have sufficient fitting properties for individual patients.Complicated structures require specialized assistants to wear them, and the weight becomes large, so it takes a long time. Wearing the device is painful for the patient, and there is no one that only focuses on the area where it is needed.

There are also brassieres for foundations, such as brassieres for beautiful breasts, bottom dolls for waistline and hip dolls, and dollars for hip babies. There are stockings to improve your health. These orthoses are made by knitting into a cylinder using nylon yarn or urethane yarn, or sewing a woven fabric. The foundation knitted in a cylindrical shape changes the size, changes the thickness and type of the thread, changes the structure, etc., according to the body shape with a knitting structure, because it partially compresses and changes the supporting force To provide the desired function. In addition, the foundation made of sewing is composed of different materials such as knitted fabrics, woven fabrics and non-woven fabrics, materials with different physical properties, and materials with different physical properties, or they are superimposed into a three-dimensional structure. There is something. However, these conventional foundations have the drawbacks of being very complex in terms of production and consequently being expensive, and have been found to correspond exactly to the different body types of different wearers. It is practically impossible to have a function as an option.

INDUSTRIAL APPLICABILITY The present invention is suitable for medical, sport, or foundation, which has a high fit, which is appropriate for the patient's symptoms and individual body shape, and which is easy to use and comfortable to wear.

In the above-described method for manufacturing a covering device, a treatment agent is applied or adhered in a liquid state or a solid state to a predetermined portion of a stretchable material constituting a main body made of a stretchable material and a non-stretchable material or a stretchable material, By integrating the treatment agent with the elastic material, the elasticity of a predetermined portion of the elastic material constituting the thick body is changed.

According to the present invention, a treatment agent is soaked in a predetermined portion of a main body made of an extensible material to change the expansion and contraction characteristics of only that portion. Therefore, it is possible to apply an appropriate acting force, that is, a fixing force, a supporting force, a pressing force, etc., to a necessary location according to the condition of the wearer of the pylon. The rational treatment and prevention can be performed. It becomes possible. In addition, since the orthosis itself has an elastic material and a processing agent such as resin integrated, the thickness and weight are almost the same as those of the elastic material, and there is a complex auxiliary belt without giving a foreign body feeling. The mounting operation is easy because it has not been done, and it can be worn by the elderly or children without any burden. Furthermore, since the treatment agent is simply applied and adhered to the elastic material without combining and sewing various materials as in the past, the manufacturing process is very simple and leads to cost reduction. .

The soaking treatment of the treatment agent may be performed before or after forming the body from the stretchable material and the non-stretchable material or the stretchable material. After forming the main body, it may be cut or sewn to form a thicker, or after forming the main body from a stretchable material and a non-stretchable material or a stretchable material, the elastic material constituting the main body May be subjected to a soaking treatment of the treatment agent at a predetermined location.

When the body is composed of elastic and non-elastic materials, it is effective for orthotics that require fixation force, for example, there are rib fracture fixation bands and low back pain bands.Specifically, it is the diseased part in rib fracture fixation Non-elastic element on the side What is necessary is just to use a material, and it is only necessary to perform soaking treatment using an elastic material on the unaffected side. For the lower back pain zone, a non-stretchable material may be used for the abdomen, and a stretchable material may be used for other areas, and the soaking treatment may be appropriately performed there. When the main body is composed of only elastic material, it is effective mainly for equipment for partially fixing, supporting, and compressing joints, and for foundations for adjusting the body shape. Joint orthoses include hand joints, elbow joints, knee joints, and ankle joints, and foundations include a hip-up gadget, a bottom girdle, and a postpartum abdomen.
