Description

  The present invention relates to a supporter attached to a joint in a body.

Conventionally, for example, a supporter has been widely used for fixing, supporting, compressing, or keeping warm the knee joint or elbow joint of the body. As such a supporter, there is one proposed in Patent Document 1, for example. This supporter has a core material having a modulus larger than that of the elastic material forming the main body on a part of the surface of the main body (supporter main body) made of the elastic material formed in a cylindrical shape, and the elongation of the core material. A reinforcing material formed by laminating a surface material that restricts the above is adhered, and the modulus of the reinforcing material is set to a size that can restrict the movement of the affected area within the range of motion. As a result, in normal daily living conditions with little changes in muscles and ligaments, the body structure can be followed only by changes, and when the movement is intense, the elasticity of the reinforcing material is added due to the change in the body only and strong. Stress acts to suppress further muscle and ligament movement.
Japanese Patent No. 2894778

  However, in the thing of the said patent document 1, since the reinforcing material which is hard to extend suddenly from the main body which is comparatively easy to extend is arranged, it is difficult for a reinforcing material to follow the movement of a knee joint part or an elbow joint part. . Therefore, for example, when used as a supporter that protects the ligaments of the knee joint and elbow joint, even if the ligaments of the knee joint and elbow joint are partially covered with a reinforcing material, When the knee joint portion moves, the reinforcing material is lifted from the knee joint portion (skin surface) and a gap is easily formed between the knee joint portion and the reinforcing material is likely to be displaced from the ligament of the knee joint portion. If such lifting or misalignment occurs, the vicinity of the knee joint cannot be properly protected and fixed.

  In addition, a part of the left end piece 74a of this embodiment also serves as a part of the first medium strong tensile stress part 71.

  The fifth middle strong tensile stress portion 75 and the sixth middle strong tensile stress portion 76 are for preventing slippage from the elbow joint after mounting, and the fifth middle strong tensile stress portion 75 is the axis of the supporter body 1. The supporter body 1 is disposed on the arm slot 11 side in the direction over the entire circumference in the circumferential direction.

  On the other hand, the sixth medium strong tensile stress portion 76 is disposed on the arm opening 12 side in the axial direction of the supporter body 1 over the entire circumference in the circumferential direction of the supporter body 1.

  The second medium strong tensile stress portions 72a and 72b to the sixth medium strong tensile stress portion 76 are formed in the same manner as the first medium strong tensile stress portion 71 (see FIG. 7).

  Moreover, in this embodiment, between the 1st side collateral ligament coating | coated part 31 and the 2nd side collateral ligament coating | coated part 32 in the front surface of the supporter main body 1, the 1st side collateral ligament coating | coated part 31 and 2nd side collateral with respect to the said ligament are provided. A positioning portion 8 for positioning the ligament covering portion 32 is provided.

  The positioning part 8 of this embodiment is displayed on the elbow head section display part 81 as the elbow head covering part forming means displayed on the surface of the outer cylindrical body 1 a of the supporter body 1 and the elbow head section display part 81. The left and right center point indicating part 82 is also comprised.

  The elbow head section display unit 81 includes two curved display pieces 81a and 81b, which are arranged so as to oppose the upper part and the lower part, and thereby cover the elbow head of the elbow part inside thereof. The elbow head covering portion 83 having a shape is partitioned so that it can be recognized by the user in appearance. The elbow head covering portion 83 is configured such that its center O is on the left-right center line O1.

  Further, the left and right center point specifying part 82 clearly shows the left and right center of the elbow head covering part 83, and the curved display piece 81 a and the left and right sides are arranged inside the upper curved display piece 81 a of the elbow head section display part 81. It is disposed at a position where the center line O1 intersects.

  Next, the manufacturing method of this elbow supporter is demonstrated. First, a tricot knitted long knitted body is formed using two types of yarns, nylon yarn and polyurethane yarn, and the long knitted body is cut into two rectangular shapes as shown in FIG. The sheet bodies 9a and 9b are manufactured.

  And the urethane type resin piece 2a is made to be scattered by apply | coating urethane type resin to the surface of one sheet body 9a of them by screen printing.

  Thereby, the first strong extension stress region portions 131 and 132, the second strong extension stress region portions 141 and 142, the third strong extension stress region portions 151 and 152, and the fourth strong extension stress region portion 160 are formed. At the same time, the first medium strong tensile stress region 171, the second medium strong tensile stress region 172 a, 172 b, the third medium strong tensile stress region 173, the fourth medium strong tensile stress region 174 a, 174 b, the fifth A medium strong tensile stress region 175 and a sixth medium strong tensile stress region 176 are formed.

  Then, the other sheet body 9b is overlaid on the surface of the one sheet body 9a. Then, in this state, bonding is performed by applying a predetermined pressure for a predetermined time at a predetermined temperature with a press machine.

  As a result, the urethane-based resin pieces 2a in the first strong tensile stress region portions 131 and 132 to the fourth strong tensile stress region portion 160 and the urethanes in the first medium strong tensile stress region portion 171 to the sixth medium strong tensile stress region portion 176. The system resin piece 2a and the sheet bodies 9a and 9b are bonded to each other.

  In this state, the supporter body 1 is formed by the two sheet bodies 9a and 9b, and each of the first strong extension stress region portions 131 and 132 to the fourth strong extension stress region portion 160 is more than the supporter body 1. First strong extension stress portions 31 and 32 to fourth strong extension stress portions 6 having strong extension stress are formed. At the same time, each of the first medium strong tensile stress region 171 to the sixth medium strong tensile stress region 176 has a tensile stress stronger than that of the supporter body 1, and the first strong tensile stress portions 31, 32 to The first medium strong extension stress part 71 to the sixth medium strong extension stress part 76, whose extension stress is weaker than the four strong extension stress parts 6, are formed.

  Here, since the tensile test of each of the supporter main body, the strong tensile stress portion, and the medium strong tensile stress portion was performed, the measurement data is shown in FIG. In this test, the test piece was stretched by 20%, 50%, and 80% in the longitudinal direction (axial direction) and lateral direction (circumferential direction) for the supporter main body, the strong tensile stress portion, and the medium strong tensile stress portion, respectively. The tensile force (gf) at the time of the acquisition was acquired and compared. Further, a test piece having a width of 25 mm was used as a test piece, and measurement was performed under the conditions of a grip interval of 10.0 cm and a tensile speed of 5 cm / min.

  As a result, the strong extension stress portion required the largest extension force, and then the supporter main body extended with the smallest extension force in the medium extension stress portion. That is, the strong extension stress portion had the strongest extension stress, followed by the medium strength extension stress portion, and the supporter body had the weakest extension stress.

  In addition, since the extensibility test was conducted together with the tensile test, the result is also shown in FIG. This extensibility test was carried out by examining the elongation rate of each test piece with an extension force of 1 kgf, 1.5 kgf, and 2.25 kgf. The tensile speed at this time was measured under the condition of 30 cm / min.

  Returning to FIG. 8, the description will be continued. After the supporter body 1 is formed by the two sheet bodies 9a and 9b as described above, the outer peripheral edge portion is cut. Thereby, the supporter for elbow joints of the unfolded state shown in FIG. 4 is obtained.

  Thereafter, as shown in FIG. 4, the positioning portion 8 is formed on the surface of the outer cylindrical body 1a constituted by the other sheet body 9b by applying paint such as paint ink. Then, for example, the right end pieces 74b provided at the left and right ends of the supporter body 1 are turned rearward, the left end pieces 74a are overlapped, and both are sewn together. In addition, in FIG. 2, the adhesion part after sewing is not represented.

  Next, the operation of the elbow joint supporter will be described. When this elbow joint supporter is attached to, for example, the elbow joint portion of the right arm, the front side of the elbow joint supporter is turned upside down so that the arm is inserted from the arm slot 11 in this state. Go through.

  At this time, since the strong extension stress portion 2 is disposed at an interval in the circumferential direction of the supporter body 1, for example, the first side collateral ligament covering portion 31 and the second side collateral ligament covering portion 32 are continuously formed. Compared with the case where it is provided on the entire circumference, it is easier to expand the diameter, and the arm can be easily passed.

  Then, the elbow head is covered with the elbow head covering portion 83 partitioned by the elbow head partition display portion 81 of the positioning portion 8, and the left and right center point indicating portion 82 is visually aligned with the substantially left and right center of the elbow head.

  Thereby, for example, the first side collateral ligament covering portion 31 covers the outer side collateral ligament, and the second side collateral ligament covering portion 32 covers the outer side collateral ligament, respectively. Further, the first forearm muscle covering portion 72a covers a part of the ulnar carpal extensor and the heel side carpal extensor, and the second forearm muscle covering portion 72b is a part of the ulnar carpal flexor and the heel side carpal flexor. Coating.

  Therefore, when wearing on the elbow joint, for example, when the user does not know the position of the inner collateral ligament or the outer collateral ligament of the elbow joint, or the first side collateral ligament covering portion 31 and the second side that are difficult to see Anyone can easily dispose the collateral ligament covering portion 32 and the first forearm muscle covering portion 72a at a predetermined position of the elbow joint, and can reliably protect and fix the ligament and muscle.

  From this state, for example, when the elbow joint is moved to bend or extend, the first collateral ligament covering part 31 and the second collateral ligament covering part 32 cover the ligament of the elbow joint part. And can protect the ligament.

  Further, at that time, the first strong tensile stress portions 31 and 32 are lifted from the elbow joint portion by the first medium strong tensile stress portion 71 arranged on the entire circumference of the first strong tensile stress portions 31 and 32, and the elbow joint portion. It is possible to suppress the formation of a gap between the ligament and the displacement from the ligament.

  Moreover, since the 1st side collateral ligament coating | coated part 31 and the 2nd side collateral ligament coating | coated part 32 are arrange | positioned at intervals, the 1st side collateral ligament coating | coated part 31 and the 2nd side collateral ligament coating | coated part 32, Can follow the movement of the elbow joint part and can move the elbow joint part smoothly, and the first side collateral ligament covering part 31 and the second side collateral ligament covering part 32 can be lifted from the elbow joint part or the elbow The positional deviation from the ligament of a joint part can be suppressed more reliably.

  Further, the second strong tensile stress portions 41 and 42 further lift the first side collateral ligament covering portion 31 and the second side collateral ligament covering portion 32 from the elbow joint portion, or further shift the position from the ligament. While being able to suppress reliably, the feeling of tension of the 1st side collateral ligament covering part 31 and the 2nd side collateral ligament covering part 32 at the time of following movement of an elbow joint part is canceled, and the sense of incongruity at the time of wearing is eliminated. be able to.

  Further, the first side collateral ligament covering portion 31 and the second side collateral ligament covering portion 32 are always drawn from both sides in the circumferential direction by the second medium strong tensile stress portions 72a and 72b, The lifting from the elbow joint portion between the first side collateral ligament covering portion 32 and the second collateral ligament covering portion 32 or the displacement from the ligament can be suppressed.

  Even if the first side collateral ligament covering portion 31 and the second side collateral ligament covering portion 32 are slightly displaced from the ligament, the first medium strong tensile stress portion 71 can cover the ligament. , Can protect the ligament efficiently.

  In the first embodiment, the second strong tensile stress portions 41 and 42 to the fourth strong tensile stress portion 6 and the second middle strong tensile stress portions 72a and 72b to the sixth middle strong tensile stress portion 76 are provided. However, it is not limited to this form and can be changed as appropriate.

  For example, one, a plurality, or all of the second strong tensile stress portions 41 and 42 to the fourth strong tensile stress portion 6 and the second medium strong tensile stress portions 72a and 72b to the sixth medium strong tensile stress portion 76 are included. It shall not be provided.

Accordingly, it is possible to prevent the ankle joint portion from becoming difficult to move due to the second medium strong tensile stress portion 462, and to reduce the possibility of hindrance to walking and the like.

  In addition, since the second strong tensile stress portion 404 is provided on the inner side of the first strong tensile stress portion 403, the heel of the ankle joint portion can be supported more firmly, and the ligament around the heel is reliably secured. Can be protected and fixed to.

  In the third embodiment, the second strong tensile stress portion 403, the third strong tensile stress portion 404, the second medium strong tensile stress portion 462, and the third medium strong tensile stress portion 463 are provided. One, a plurality, or all of the above may not be provided. Alternatively, instead of one or both of the second strong tensile stress portion 403 and the third strong tensile stress portion 404, a medium strong tensile stress portion is provided, and the second medium strong tensile stress portion 462 and the third medium strong tensile stress are provided. A strong extension stress portion may be provided instead of one or both of the portions 463. The above is the description of the third embodiment.

  The shape and the like of the first strong extension stress portion are not limited to those of the first to third embodiments, and can be changed as appropriate. In the first to third embodiments, the first medium strong tensile stress portion is disposed adjacent to and in contact with the first strong tensile stress portion. You may make it arrange | position with a space | interval from a 1st strong extension stress part, and can change suitably.

  However, if the first medium strong tensile stress portion is adjacent to the first strong tensile stress portion, the tensile stress can be gradually increased from the supporter body to the first strong tensile stress portion, and the first intermediate strong tensile stress portion is arranged at an interval. Compared to the above, it is possible to make the first strong extension stress portion easy to follow the movement of the joint portion, and it is preferable to make the first strong extension stress portion adjacent to each other.

  Further, in the above embodiment, the strong tensile stress portion and the medium strong tensile stress portion are configured such that synthetic resin pieces are interspersed between the outer cylindrical body and the inner cylindrical body of the supporter body. However, it is not limited to this form, and can be changed as appropriate.

  For example, one or both of the strong tensile stress portion and the medium strong tensile stress portion are formed in a part of the supporter body having a stronger tensile stress than the supporter body by changing the knitting yarn or knitting method from the supporter body. Alternatively, one or both of the strong extension stress portion and the medium strength extension stress portion is composed of a sheet body made of a synthetic resin or the like separately formed from the supporter main body so that the extension stress is stronger than the supporter main body, and the supporter main body You may form so that it may stick to. However, if the strong tensile stress portion and the intermediate strong stress portion are configured by interspersing the synthetic resin pieces as in the above embodiment, the strong tensile stress portion and the intermediate strong stress portion can be easily placed at predetermined positions. It is advantageous to construct the strong extension stress portion and the medium strength extension stress portion so that the synthetic resin pieces are scattered at that point.

  Further, in the case of forming the strong tensile stress portion and the medium strong tensile stress portion by interspersing the synthetic resin pieces between the outer cylindrical body and the inner cylindrical body of the supporter body, the synthetic resin pieces used are: Not limited to urethane-based ones, they can be used with appropriate modifications.

  Further, in the above embodiment, by changing the area ratio of the interspersed portion and the non-spotted portion of the synthetic resin piece, the strong extension stress portion is made stronger in the extension stress than the medium strength extension stress portion. Not only the form but also can be changed as appropriate.

  For example, the thickness of the synthetic resin piece in the strong tensile stress portion is made larger than the thickness of the synthetic resin piece in the medium strong tensile stress portion, and the strong tensile stress portion is made to have a stronger tensile stress than the medium strong tensile stress portion. good.

  Moreover, in the said embodiment, although the 1st middle strong extension stress part is arrange | positioned so that the perimeter part of a 1st strong extension stress part may be enclosed, for example, a 1st middle strong extension stress part is 1st strong. You may make it arrange | position except a part of circumference | surroundings of an extension stress part. Therefore, the “entire circumferential portion” referred to in the present application includes almost the entire circumferential portion except for the whole circumferential portion and a part of the circumferential portion.

  Further, the supporter of the present invention is not limited to those for elbow joints, knee joints, and ankle joints, and can be used, for example, for wrist joints or for shoulder joints, and can be changed as appropriate.
