Description

  The present invention relates to elastic socks, particularly for medical use used for the prevention or treatment of diseases such as venous return disorder of the lower limbs and lymphedema, or for the prevention or reduction of fatigue and swelling of the lower limbs in daily life. It relates to elastic socks. Examples of the elastic socks that are the subject of the present invention include pantyhose that covers from the waist to the foot, stockings that cover from the thigh to the foot, and high socks that cover from the knee to the foot. In addition, in the said various forms, you may not partially cover a leg part below a buttocks part, a foot tip part, or an ankle part.

  Elastic socks are used for the prevention of diseases such as venous return disorders such as varicose veins and venous thrombosis in the lower limbs and lymphedema, or in combination with treatments such as surgical operations and drug therapy for the diseases. This elastic sock is designed to compress the lower limb more strongly from the outside than ordinary socks. In order to effectively promote venous return, the pressure sock is gradually increased from the ankle to the thigh. Is designed to be weak (see, for example, Patent Document 1).

  Patent Document 1 discloses an invention relating to “a stocking worn to improve a leg that has become thick due to a venous return disorder or a lymphatic reflux disorder”, and the compression pressure as shown in FIG. The pressure distribution is disclosed. As shown in FIG. 4, by increasing the tightening pressure as it goes from the thigh F2 to the foot tip F1, the return of body fluid is promoted, and the venous return can be effectively promoted.

  In addition, various elastic socks for treatment have been proposed in which the pressure distribution to the lower limbs by the elastic socks is a special distribution depending on the purpose of treatment.

  By the way, when wearing various conventional elastic socks, the specific part of the socks depends on its monotonous cylindrical shape, highly stretchable fabric, individual body type difference, sock size and type, etc. There is a case where it is not worn on the intended lower limb region, and in this case, there is a problem that the compression pressure distribution applied to the socks is not effectively exhibited.

  In addition, this type of socks has a very strong elasticity because it applies a strong pressure to the lower limbs, and requires a large force when worn. Therefore, it is not easy for women, elderly people, patients with joint disorders, and the like, and the difficulty of wearing socks at an appropriate site is further increased. In view of the circumstances in which venous return disorders are likely to occur particularly in women and the elderly, the above problem becomes an important problem in preventing and treating diseases.

  Furthermore, the elastic socks may be used repeatedly after washing, but depending on the usage situation, the knitted fabric of the socks may gradually loosen or the yarn may stretch, causing the socks to relax from the original state. It can happen. When the socks are worn in the slack state, proper compression cannot be obtained even if the socks are worn at an appropriate site. Usually, since an appropriate mounting position is not clear, there are many cases where the mounting is repeatedly performed without noticing the slack. In the case of loosening, even if it is attached to an appropriate part at the time of next wearing, it will be worn in a loose state. Therefore, unless it is determined whether it is slack and is replaced with a new sock at the appropriate time, a sufficient preventive and therapeutic effect cannot be expected in the long term.

Japanese Utility Model Publication No. 3-85025

  The present invention has been made in view of the above-described problems, and an object of the present invention is to make it possible to accurately wear a sock at a predetermined position and to apply an appropriate compression pressure to the lower limb, thereby providing a leg vein. An object of the present invention is to provide an elastic sock that can effectively prevent or treat diseases such as reflux disorder. It is another object of the present invention to provide an elastic sock that makes it easy to determine the presence or absence of slack in a sock after being used a plurality of times, and that can provide a sufficient preventive and therapeutic effect over the long term.

  In order to solve the above-mentioned problem, the present invention covers at least the ankle part and the calf part, and in the elastic sock comprising a compression pressure distribution in which the compression pressure gradually decreases from the ankle part to the calf part, the ankle part, A mark for part recognition is provided on at least one part of the calf (claim 1).

  Further, the present invention provides an elastic sock that covers at least the ankle part, calf part, knee part, and thigh center part, and has a compression pressure distribution in which the pressure pressure gradually decreases from the ankle part to the thigh center part. A part recognition mark is provided on at least one part of the calf part, knee part, and thigh center part (claim 2).

The invention of claim 1 is a high socks type elastic sock, and the invention of claim 2 is an invention related to a stocking type elastic sock. According to the present invention, in any case, the sock is accurately placed at a predetermined position. The desired therapeutic effect can be obtained. Also, if wearing based on the part recognition mark, there will be almost no difference in positional relationship with the previous wearing, so if socks loose, it will be easier to determine the looseness based on the wearing discomfort .
By the way, the part where the mark is provided may be at least one part of the ankle part, the calf part, the knee part, and the thigh center part, but in order to accurately wear the entire lower limb, the part where the mark is provided is The larger the number, the better, for example, in the case of the invention of claim 2, it is preferable to provide it in all the above-mentioned parts. Of the above portions, the vertical center portion of the socks such as the knee is difficult to align when worn. Therefore, if a guide is provided at this portion, the handleability is improved.

  As an embodiment of the invention of claim 1 or 2, inventions of claims 3 to 10 below are preferable. First, in the elastic sock according to claim 1 or 2, the ratio of the compression pressure of the ankle part, the calf part or the thigh center part is 44 to 40 when the compression pressure of the ankle part is 100. 80, the center of the thigh is in the range of 20 to 65 (claim 3). Further, in the elastic sock according to claim 1 or 2, the pressure of the ankle part, calf part or thigh center part is 21 to 67 hPa, 9 to 54 hPa, 4 to 44 hPa, respectively. (Claim 4). Based on the above, compression pressure and compression pressure distribution suitable for compression therapy and thrombus prevention can be obtained.

  In addition, the compression pressure of each said part is defined as a measurement pressure based on the following measurement parts and measurement methods. First, the measurement site | parts of the said ankle part, calf part, and thigh center part are as follows, respectively. That is, the ankle part is the minimum leg part, the calf part is the maximum leg part, and the thigh center part is the center part between the crotch part and the patella center part.

  The pressure measurement method is as follows. That is, a pressure measuring device MST (manufactured by Salzmann AG) is used, and measurement is performed according to the following procedure. First, a probe of a measuring instrument is installed on the hard wooden or plastic foot. The foot shape has a cylindrical section with a circumference equivalent to the average Japanese body shape, and the foot shape specified there is used for measurement according to the sock size shown below. In addition, when the applicable perimeter of the sock extends over a plurality of sizes, an ankle having the ankle perimeter that is closest to the median of the ankle applicable perimeter of the sock is used for the measurement.

Size 1: Socks with an applicable perimeter in the range of 15 to 19 cm at the ankle and 24 to 30 cm at the calf. An ankle with a circumference of 17 cm at the ankle, 27 cm at the calf, and 41.2 cm at the center of the thigh is used.
Size 2: Socks whose applicable perimeter is in the range of 17 to 21 cm at the ankle and 28 to 34 cm at the calf. An ankle with a circumference of 19 cm at the ankle, 31 cm at the calf, and 44.7 cm at the center of the thigh is used.
Size 3: Socks with an applicable perimeter in the range of 19-23 cm at the ankle and 32-38 cm at the calf. An ankle with a circumference of 21 cm at the ankle, 35 cm at the calf, and 46.5 cm at the center of the thigh is used.
Size 4: Socks having an applicable perimeter in the range of 21 to 25 cm at the ankle and 36 to 42 cm at the calf. An ankle with a circumference of 23 cm at the ankle, 39 cm at the calf, and 48.4 cm at the center of the thigh is used.
Size 5: Socks with an applicable perimeter in the range of ankle 23-27 cm and calf 40-46 cm. A foot with a circumference of 25 cm at the ankle, 43 cm at the calf, and 51.1 cm at the center of the thigh is used.
Next, an elastic sock is attached to the foot mold, the pressure at each part is measured, and this value is taken as the compression pressure.

  Further, in the elastic sock according to any one of claims 1 to 4, the mark can be visually or tactilely recognized (claim 5). When tactile recognition is possible, it is particularly useful when a person with low vision or a blind person wears it.

  Further, in the elastic sock according to any one of claims 1 to 5, the mark can be recognized from both front and back of the sock (claim 6). When wearing a sock, a sock that is wound with its back side (side in contact with the skin) facing outwards may be rewound. By enabling the mark to be recognized from the back side as in the sixth aspect of the invention, it is possible to easily mount the mark at an appropriate position even in the case of the above mounting.

  Further, in the elastic sock according to any one of claims 1 to 6, the mark is provided continuously or repetitively around the sock. ). In this way, since the position of the mark can be recognized from any angle, the operation is simplified not only when the wearer wears the sock himself but also when the assistant wears the socks.

  Furthermore, in the elastic socks according to any one of claims 1 to 7, the mark changes into a predetermined shape when the cloth is stretched by a predetermined ratio as the socks are attached. (Claim 8). By doing so, it is possible to easily recognize whether a specific compression pressure is applied to the wearing site during the wearing of the socks or whether the compression pressure is applied uniformly. In particular, when sock slack occurs, it becomes easy to determine the slack based on the change in the mark shape.

  The elastic sock according to any one of claims 1 to 8, wherein the mark is a yarn knitted into a knitting structure of the sock, and the yarn for the mark is a knitting of the sock. The main yarn constituting the structure is different from the main yarn, and the yarn different from the main yarn is visually or tactilely identifiable (claim 9). . Furthermore, in the elastic sock according to claim 9, the knitting structure of the sock includes a yarn constituting a stitch and an elastic yarn inserted in a lateral direction of the stitch, and the yarn for the mark is A part of the yarn constituting the stitch is formed (claim 10). Although details will be described later, according to the above configuration, the mark yarn is incorporated as a part of the knitting structure of the sock, so that the mark has excellent durability. Furthermore, since the warp yarn constituting the stitch has less influence on the compression pressure of the sock than the elastic yarn inserted in the lateral direction, the mark can be provided while ensuring an appropriate compression pressure.

  According to the present invention, it is possible to easily recognize where the sock should be worn, so that the sock can be worn at a predetermined position, and as a result, it is possible to apply an appropriate compression pressure to the lower limb, It can effectively prevent or treat diseases such as lower limb venous return disorder. In addition, it is possible to provide an elastic sock that can easily determine whether or not the sock is slack after being used a plurality of times, and can obtain a sufficient preventive and therapeutic effect even in the long term.

  An embodiment of the present invention will be described with reference to FIGS. In addition, in each figure, the same number is attached | subjected to the same functional member. 1A and 1B are diagrams showing a state where an elastic sock according to an embodiment of the present invention is attached to a lower limb. FIG. 1A is a diagram related to a stocking type elastic sock, and FIG. 1B is a diagram related to a high sock type elastic sock. It is. FIG. 2 is a partially enlarged view of an example of the mark portion of the elastic sock according to the embodiment of the present invention, wherein a) is a state diagram before mounting, and b) is a state diagram after mounting. FIG. 3 is a view showing a knitting structure including a mark portion of the elastic sock according to the embodiment of the present invention.

  First, FIG. 1 will be described. In FIG. 1 a), 1 is a stocking type elastic sock, and this embodiment passes from the toe portion 2 to the heel portion 3, the ankle portion 4, the calf portion 5, the knee portion 6, and the thigh center portion 7, The elastic sock of the type which covers to the foot mouth part 8 of an upper end is shown. 20 is a mark that makes it possible to recognize which part of the lower limb the stocking should be worn. In the present embodiment, the mark 20 is the four parts of the ankle part 4, the calf part 5, the knee part 6, and the thigh center part 7. It is formed as a continuous straight line.

  Next, FIG. 1b) will be described. In FIG. 1 b), 1 is a high sock type elastic sock according to the present invention. This embodiment is such that the foot passes from the toe portion 2 to the heel portion 3, the ankle portion 4, the calf portion 5, and below the knee portion 6. An elastic sock of the type covering up to the mouth 8 is shown. In the present embodiment, the mark 20 is formed as a straight line continuous around the two portions of the ankle portion 4 and the calf portion 5.

  As the knitting structure in the elastic sock of the present invention, a knitting structure similar to the conventional one can be adopted, and for example, flat knitting, rubber knitting, pearl knitting and the like can be used. Also, the yarn used can be the same as the conventional yarn, nylon multifilament can be used as the yarn constituting the stitch of the knitted structure, and polyurethane elastic yarn can be used as the yarn inserted from the lateral direction into the stitch. The elastic yarn inserted in the lateral direction is particularly preferably a covered yarn in which a polyurethane elastic yarn is used as a core yarn and other yarn is wound around the polyurethane yarn. The compression pressure of the socks can be given a predetermined value by controlling the density of the yarn, the size of the stitches, and the degree of stretch of the elastic yarn.

  Next, details of the mark will be described below. As described above, the position where the mark is placed may be provided in at least one part of the ankle part, calf part, knee part, and thigh center part. Moreover, it should just be provided in either one of the front side (side which does not contact skin) of a sock, or a back side (side which contacts skin), but the direction provided in both front and back is more preferable.

As the shape of the mark, a point, a line, a geometric pattern, a figure or the like can be adopted, and these may be partially installed on the part, or may be continuously or repeatedly installed. In particular, it is preferable to install it continuously or repeatedly around the sock because the position of the mark can be recognized from any angle when worn. Further, it is preferable to form the mark shape so that the mark changes into a specific shape when the sock fabric is stretched to a specific degree. By doing so, the mark can also be used as a standard for recognizing whether a specific compression pressure is applied to the wearing part when wearing the socks. This is based on the fact that the following relationship is established about the tension when a specific part of the sock is stretched in the circumferential direction and the pressure applied to the surface of the part.
Compression pressure (kPa) = 20π × tension (N / cm) / perimeter of target site (cm)

  Next, FIG. 2 will be described. FIG. 2 a) is an enlarged view of the mark portion of the sock before wearing, and the mark is formed by repeatedly providing a rectangular figure 21 around the sock, and is formed by, for example, dye printing. This embodiment shows an example in which the size of the rectangle is designed so that the rectangle 21 is transformed into a square 22 as shown in FIG. 2B) when a specific tension is applied to the sock fabric at the time of wearing. .

  Next, a method for forming marks on socks will be described. As a method of forming the mark, a thread different from the main thread constituting the knitting structure of the sock is knitted (sewn) into the knitting structure of the sock, and a hole or a slit is partially formed in the knitting structure. There are a method of knitting socks so that the slit portion can be recognized as a mark, a method of printing dyes or applying a resin as described above, a method of sticking an adhesive sheet or tape on a predetermined position of a stocking, and the like.

  Of the various forming methods described above, a method of knitting a yarn is preferred. The reason is that the yarn for this mark can be knitted at the same time as the knitting process when manufacturing the socks, which is advantageous in terms of manufacturing. Excellent mark. As the yarn for the mark, the main yarn constituting the knitting structure of the sock is different from the appearance of color, thickness, shape, etc., and can be recognized visually or tactilely. Moreover, it is preferable that the mark yarn is knitted so as not to break the balance of the compression pressure of the socks, and is continuously inserted linearly around the socks, and the line width is preferably 0.05 to 50 mm. . In particular, it is preferable that the knitting structure of the sock is constituted by a yarn constituting the stitch and an elastic yarn inserted in the lateral direction of the stitch, and the mark yarn is adopted as the yarn constituting the stitch. This is because the yarn constituting the stitch has less influence on the compression pressure of the sock compared to the elastic yarn inserted in the lateral direction, and therefore it is easy to ensure an appropriate compression pressure. When the mark yarn is adopted as the yarn constituting the stitch, the stitch may be formed only by the mark yarn, or the main yarn constituting the sock stitch (yarn other than the mark yarn). Alternatively, the yarns to be marked may be inserted along or in parallel, and the stitches may be formed by the two yarns.

  FIG. 3 is an enlarged view of the knitting structure, in which 30 is a yarn constituting a continuous stitch in the longitudinal direction, 31 is an elastic yarn inserted in the transverse direction, and these two yarns constitute the knitting structure of the sock. It is a thread. Reference numeral 32 denotes a mark yarn, which constitutes a part of a sock stitch, for example, has a color different from 30 and 31, and is visually recognizable. In addition, the longitudinal direction as used in the field of this invention means the direction parallel to the manufacturing direction of a knitted fabric, and the waling direction of a knitted fabric corresponds normally. On the other hand, the horizontal direction means a direction orthogonal to the vertical direction, and usually corresponds to the course direction of the knitted fabric.

  Regardless of the method of knitting the mark yarn into the knitted structure, when a method of printing the dye or applying a resin is employed, a known method can be used, for example, inkjet printing, transfer printing, screen printing, etc. Can be mentioned. Moreover, synthetic resin can be applied to the stocking surface, and unevenness can be formed on the surface of the sock depending on the coating thickness, or the tactile sensation can be changed only at the portion where the resin is applied, so that the mark can be recognized tactically. This is particularly useful when a person with low vision or a blind person wears himself.

  Moreover, when an adhesive sheet or a tape is affixed to a predetermined position of the stocking, it can be removed after being mounted, and the aesthetics at the time of mounting is improved.

  Next, examples of the present invention will be described below.

  A flat knitted structure is composed of 50 denier white nylon multifilament, and a 520 denier white covered yarn covering the nylon filament with polyurethane elastic yarn as the core yarn is inserted in the lateral direction of the stitch to form a stocking type sock. . This sock size corresponds to the above-mentioned size 3, and the compression pressure distribution of this elastic sock was 24 hPa at the ankle, 19 hPa at the calf, and 11 hPa at the center of the thigh.

  The mark was formed by inserting a blue polyester multifilament only one course as a stitch of a flat knitted structure when the ankle part and knee part of the nylon multifilament were knitted. Since the mark is formed in a straight line around the ankle and knee and can be visually recognized from both the front and back of the sock, the sock can be easily adjusted to a predetermined position when worn.
