Description

The present invention relates to socks. More particularly, it relates to an elastic sock that can be worn in place and under proper compression.

Conventionally, elastic socks have been used for the prevention or treatment of venous return disorders such as varicose veins and venous thrombosis in the lower extremities and diseases such as lymphedema. Such socks are also used to prevent or alleviate fatigue and swelling of the lower limbs in daily life.

Compared to ordinary socks, these elastic socks are designed to strongly compress the lower limbs from the outside, and in order to effectively promote venous return, they are gradually worn from the ankle to the thigh. Designed to reduce pressure. When wearing such elastic socks, specific parts of the sock may not be worn on the intended lower extremity part due to the monotonous cylindrical shape of the sock, individual differences in body shape, size of the sock, etc. There is a problem that the compression pressure distribution applied to the sock is not effectively exhibited. In addition, since this type of socks exerts a strong pressure on the lower limbs, it has very strong elasticity and requires a great deal of force when worn, so it is not suitable for women, the elderly, and patients with joint disorders. , it is not easy to put on, which further increases the difficulty of putting the sock on the right part. In order to solve such a problem, there has been proposed an elastic sock having a predetermined compression pressure distribution and a sock provided with a mark for recognizing the wearing site (see Patent Documents 1 and 2).

The knitting structure of the sock 10 can employ a conventionally known knitting structure, and for example, flat knitting, rubber knitting, pearl knitting, or the like can be used. Also, conventionally known yarns can be used. For example, nylon multifilament can be used as the yarn forming the stitches of the knit structure, and polyurethane elastic yarn can be used as the yarn inserted into the stitches from the lateral direction. As the elastic yarn inserted in the lateral direction, it is preferable to use a covered yarn in which another yarn is wound around a polyurethane elastic yarn as a core yarn. A predetermined value can be applied to the sock by controlling the density of the yarn, the size of the stitches, and the degree of elongation of the elastic yarn.

In the present technology, the compressive pressure applied to the lower limbs is not particularly limited, but it is preferable to provide a compressive pressure distribution in which the compressive pressure decreases sequentially from the ankle portion 3 to the calf portion 4 . For example, when the compressive pressure of the ankle 3 is 100, the ratio of the compressive pressure of the calf 4 is preferably in the range of 44-80. In addition, when the sock 10 covers up to the central thigh portion 7 , it is preferable to have a compressive pressure distribution in which the compressive pressure gradually decreases from the ankle portion 3 to the central thigh portion 7 . For example, when the compression pressure on the ankle 3 is 100, the compression pressure on the calf 4 is preferably in the range of 44-80, and the compression pressure on the central thigh 7 is preferably in the range of 20-65. As a result, a compression pressure and compression pressure distribution suitable for compression therapy, thrombus prevention, and the like can be obtained.

Further, the compressive pressure of the ankle 3, calf 4, or central thigh 7 is preferably 15 to 67 hPa, 9 to 54 hPa, and 4 to 44 hPa, respectively. As a result, a compression pressure and compression pressure distribution suitable for compression therapy, thrombus prevention, and the like can be obtained. The compressive pressure of each part can be measured with respect to the measurement site defined as follows using, for example, a pressure measuring device MST (manufactured by Salzmann AG). That is, the ankle part 3 is the minimum circumference of the lower leg, the calf part 4 is the maximum circumference of the lower leg, and the central thigh part 7 is the central part between the crotch and the central part of the patella.

For example, as shown in FIGS. , dots, lines, geometric patterns, characters, drawings, etc., or a combination of one or more shapes. In addition, when forming so that it can be identified by tactile sensation, a method using a knitting structure that changes the texture such as unevenness on the surface fabric of the sock, a material other than the yarn constituting the knitting structure such as resin, ink, etc. A method of applying or impregnating to give a change in tactile sensation can be used. Moreover, these may be provided partially at the target site, or may be provided continuously, repeatedly, or discontinuously. In the present technology, it is particularly preferable to provide continuously or repeatedly around the sock 10 because the position of the position teaching portion can be recognized from any angle when worn.

In addition, in the present technology, as the position teaching part, in particular, as shown in FIGS. preferable. As a result, not only doctors, nurses, caregivers, etc., but also the wearer himself/herself can visually and reliably grasp the wearing site, as compared with the case where the position is taught by mere lines or the like. The name of the part to be worn corresponds to the target part. If it is 11, it is "toe (toe)", etc., if it is the heel position teaching part 21, it is "heel (heel)", if it is the knee position teaching part 61, it is "knee (knee)", etc. Characters or drawings corresponding to these names can be used. In addition, in the present technology, it is preferable that the name of the wearing part is indicated by characters or drawings on at least one of these position teaching portions. preferably.

In addition, in the present technology, the position teaching unit is configured so that the characters or drawings can be visually recognized when viewed from the leg opening side of the sock 10, as shown in FIGS. It is preferable that the As a result, when a person wearing the sock 10 looks at the foot from above, the character can be confirmed in the normal reading direction, so that the wearing part can be confirmed with certainty. In the present technique, the position teaching part can be provided on the front side (the side that does not contact the skin) and/or the back side (the side that contacts the skin) of the sock 10, but it is preferable to provide it at least on the front side of the sock 10.

Methods of forming the position teaching portion include a method of knitting (stitching) threads into the knitting structure of the sock 10 that are different from the main threads constituting the knitting structure of the sock 10, and a method of partially forming holes or slits in the knitting structure. However, there are a method of knitting the sock 10 so that the holes and slits can be recognized as a position teaching portion, a method of printing dye or applying resin, a method of attaching an adhesive sheet or tape to a predetermined position of the sock, and the like. . In the present technology, a method of knitting threads is particularly preferable as a method of forming the position teaching portion. As a result, the yarn for the position teaching portion can be knitted simultaneously with the knitting process when manufacturing the sock 10, which is advantageous in terms of manufacturing and can be incorporated as part of the knitted structure of the sock 10. As a result, the position teaching portion has excellent durability.

The thread for the position teaching portion may be visually or tactilely recognizable, having a different appearance such as color, thickness, shape, etc. from the main threads constituting the knitted structure of the sock 10. . Moreover, it is preferable that the thread serving as the position teaching portion is woven to the extent that the balance of the compression pressure of the sock 10 is not disturbed, and is continuously inserted in a line around the sock 10. The width of the line is 0.5 mm. 05 to 50 mm is preferred.

In the present technology, in particular, the knitting structure of the sock 10 is composed of yarns that form stitches and elastic yarns that are inserted in the lateral direction of the stitches, and yarns for the position teaching portion are adopted as the yarns that form the stitches. preferably. As a result, the thread forming the stitches has less influence on the compressive pressure of the sock 10 than the elastic thread inserted in the lateral direction, making it easier to secure an appropriate compressive pressure. In addition, when the yarn for the position teaching portion is adopted as the yarn constituting this stitch, the stitch may be formed only by the yarn for the position teaching portion, or the main yarn (position The thread for the position teaching portion may be inserted along or parallel to the thread other than the thread for the teaching portion, and the two threads may be used to form a stitch.

In addition, when the method of printing the dye or applying the resin is adopted instead of the method of weaving the thread for the position teaching portion into the knitted structure, a conventionally known method can be used, such as inkjet printing and transfer printing. , screen printing, and the like. In addition, synthetic resin is applied to the surface of stockings, and unevenness is formed on the surface of the sock depending on the thickness of the application, or the tactile sensation is changed only at the resin-applied portion, so that the position teaching portion can be tactilely recognized. can also In this way, it is particularly helpful for people with poor eyesight to put the sock 10 on themselves. In addition, when an adhesive sheet or tape is attached to a predetermined position of the sock, it can be removed after the sock is worn, thereby improving the aesthetic appearance of the sock when worn.
