Abstract

PROBLEM TO BE SOLVED: To obtain a bandage for medical treatment and sports which has excellent fixability to a lesion and does not slip and loosen. SOLUTION: The elongation rate in the longitudinal direction of the bandage is specified to 10 to 40% and the elongation rate in the transverse direction thereof to 4 to 15%. Twisted yarn is used for the yarn of the bandage and the picks of the warp in the longitudinal direction and the weft in the transverse direction are specified to >=25 pieces for both per inch, by which a twill fabric is formed. As a result, the easily usable bandage which has slight elongatability in the transverse direction as well while the elongation rate in the longitudinal direction is lowered is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bandage,
In particular, the present invention relates to a bandage for medical use and sports used for prevention of trauma occurrence, recurrence prevention, emergency treatment such as fixation and compression of an affected part, and treatment.

[0002]

2. Description of the Related Art Conventionally, prevention of injuries such as sprains in the human body, especially joints such as ankle joints and hand joints, and loosening of the thighs and the like,
In order to respond to medical purposes such as emergency treatment when receiving these injuries, assistance in rehabilitation from injuries to complete recovery, and prevention of recurrence of injuries, bandages and taping tapes are mainly used. And supporters are used. Taping tapes and supporters that use adhesives have their own advantages, but
It is easy to follow the affected area, it can be wound while adjusting the fixing force by yourself, it does not apply excessive force to body movement, stable stability is obtained, and it can be used repeatedly It is one of the useful things because of its economic efficiency.

[0003] In sports such as soccer, rugby, and American football, there are many contacts between competitors, and sprains and loosening occur frequently. For prevention and recurrence prevention,
It is said that fixation of joints is effective. Especially in the sucker, the ball is controlled by the subtle movement of the toes,
In order to cut a fine cut, even when fixing the ankle joint, appropriate fixation and flexibility are required, and fit to shoes is also required. For these reasons, the bandage has an appropriate degree of fixation and flexibility for movement, can be wound without any special technique, and can be washed and used repeatedly. Widely used.

However, most conventional bandages have a high elasticity with an elongation ratio described below (conforming to JIS L1096, hereinafter the same) under load of 70 to 100%. This bandage tends to have a large elongation and a weakening of the fixing force. Also, once the bandage is fixed, it loosens in order to gradually recover to its original state. It may cause discomfort. In addition, there are many things with plain weave and relatively low weave density,
Changes in physical properties such as deterioration and elongation rate due to repeated use were likely to occur.

Some plain woven fabrics with an elongation ratio of about 30% are also known, but since they hardly elongate in the width direction, they are fixed when wound around a relatively flat affected part. However, in some cases, it is difficult to follow a curved surface portion such as an ankle joint, so that it is difficult to wind and sufficient fixability cannot be obtained.

[0006]

DISCLOSURE OF THE INVENTION The present invention provides sufficient fixation to an affected part, improves followability even to a curved surface part, prevents easiness of displacement, and removes an affected part during use. An object of the present invention is to provide a bandage that can be securely fixed and maintained without a sense of incongruity and that can be used repeatedly.

[0007]

According to the present invention, a bandage is formed so as to have a relatively low elongation ratio in the length direction and a small elongation ratio in the width direction. The elongation rate in the length direction is about 10-40%, and the elongation rate in the width direction is about 4-15%
It should be about. Such elongation rates in the length and width directions can be obtained by making the woven fabric a twill weave. Further, by controlling the number of warps in the length direction and the number of wefts in the width direction per inch and using a twisted yarn as the yarn, a more preferable bandage can be obtained.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The bandage of the present invention is preferably formed of a woven fabric, and it is difficult to obtain the above-described low elongation rate because a knitted fabric has high elasticity and bulkiness as a whole. There are many, and the volume increases by winding. The woven fabric is formed by a single yarn of various natural fibers or chemical fibers, or an appropriate blended yarn of these fibers, preferably a single yarn of cotton, rayon, nylon, polyester, acrylic or the like, or a blended yarn of these. It is good to In addition, cotton with good moisture absorption and good touch, polyester with appropriate waist and excellent stability and familiarity with other fibers, light and soft and easy to dye acrylic, etc. alone or these Properly combined blended yarns can be used successfully.

The woven fabric using the above fibers is preferably a twill rather than a plain woven. The twill is 1/2 twill, 2/2
Aya, 1/3 Aya, 2/3 Aya, 3/3 Aya, 1/4 Aya, 2/4
The use of a twill, a 3/4 twill, a 4/4 twill, etc. is often preferable because the manufacturing process is simple, the stability of the structure is good, and appropriate strength is obtained.

[0010] The thickness of the yarn is preferably about 10 to 80 counts, and more preferably 20 to 40 counts. If the number of yarns is less than 10th, the yarn is too thick and the bandage becomes stiff, and the structure is not stabilized, and shrinkage or distortion occurs, which is unfavorable because the whole becomes hard. On the other hand, if the yarn is higher than 80, crepe is easily formed on the surface because the yarn is thin, and the durability of the whole woven fabric is low.

The yarn is preferably a twisted yarn such as a twin yarn which has high strength and has a tight feeling when woven. When a twin yarn is used, a single yarn is preferably Z-twisted, and two of the single yarns are S-twisted to form a twin yarn. For warp, the number of twists is about 1000-2500 times / m
And preferably about 1200 to 2000 times / m. In this case, if the number is less than 1,000, the elasticity is not sufficient, the strength of the yarn is low, and the woven fabric is apt to set. On the other hand, when the number of times exceeds 2,500, crimping is liable to occur, the yarn becomes hard and the feel becomes poor. For weft, the number of twists is about 200 to 1000
When the number is about times / m, a yarn having sufficient yarn strength and good finish can be obtained.

The density of the yarn is preferably such that one of the warp in the length direction and the weft in the width direction is about 1 to 1.7 times the other, and
It is preferable that the number of hits per inch is 25 or more, and that it is not very sparse. For example, about 30 to 55 threads per inch for a 20th to 30th thread, and about 40 to 80 threads for a 40th thread. The fabric weight is about 125 ~
It is often preferable to set it to about 460 g / m ² . Thus,
10-40% elongation in the length direction, 4-15% elongation in the width direction
% Bandage can be obtained.

[0013]

EXAMPLE As the warp, a single yarn of 100% cotton yarn was Z-twisted at 1700 times / m and the twin yarn was S-twisted at 1900 times / m to use a 40th yarn. 400% single yarn of 100% cotton yarn for the weft
, And the twin yarn was S-twisted at 400 times / m. 54 warp yarns per inch and weft yarns
The bandage was formed by using 41 twelve punches and a 2/2 twill weave.

Comparative Example 1 A single yarn of 100% cotton yarn was used as the warp for 17 days.
Z twisted at 00 times / m, and the twin yarn was S twisted at 1900 times / m.
A count twin yarn was used. As the weft, a 20% twin yarn in which a 100% cotton single yarn was Z-twisted at 400 times / m and the twin yarn was S-twisted at 400 times / m. The above warp per inch
45 bands and 19 wefts were used, and a plain weave was used to form a bandage.

Comparative Example 2 A single yarn of 100% cotton yarn was used as the warp for 17 days.
Z twisted at 00 times / m, and the twin yarn was S twisted at 1900 times / m.
A count twin yarn was used. As the weft, a 20% twin yarn in which a 100% cotton single yarn was Z-twisted at 400 times / m and the twin yarn was S-twisted at 400 times / m. The above warp per inch
The bandage was formed by plain weaving with 45 yarns and 41 wefts.

The physical properties of the above Examples, Comparative Examples 1 and 2 were measured as follows. ○ Elongation rate: According to JIS L1096 (constant speed elongation method), grip the test piece at 20cm (5cm in the width direction), attach it to a tensile tester, and apply a load at a pulling speed of 100% of the gripping interval per minute. Draw an elongation curve. The elongation ratio under a load of 14.71 N is determined from this curve, and expressed as an average of three times. The test piece is 30cm long x 5cm wide and 10cm long in the width direction for measurement in the length direction.
× A test piece having a width of 5 cm was used. Elongation% = {(L1-L0) / L0} × 100 L0: Grip interval 20 cm (5 cm in width direction), L1: 14.71N
Length of gripping interval when applying a load of (cm) ○ Thickness: 5 different samples according to JIS L1096 (thickness)
Using a thickness measuring device, the initial load was 0.25N / cm ²
The thickness after 10 seconds was measured by applying a load (500 g load to a φ2.5 cm holder), and expressed as an average value. ○ Elongation recovery rate, residual strain rate: In accordance with the constant load method of JIS L1096 (elongation recovery rate and residual strain rate), a test piece of 30 cm long x 5 cm wide is marked at 20 cm intervals and a load of 14.71 N is applied. One hour later, measure the length between labels. Next, the length between the labels 1 hour after debulking was measured, and the elongation recovery rate was determined by the following formula, and the average of three times was expressed. The higher the value, the better the recovery rate. Elongation recovery rate (%) = ｛(L1-L1 ′) / (L1-L
0)｝ × 100 Residual strain rate (%) = {(L1−L0) / L0} × 100 L0: Length between original signs 20 cm, L1: Between signs after applying 1.5 kg load for 1 hour Length (cm), L1 ': Length between markers when initial load is applied 1 hour after debulking (cm) ○ Decrease in elongation: Wear bandage to 12 ankle joints for 12 hours And wash. This step is regarded as one time, and this is repeated 30 times under the same conditions, and the average value of the elongation ratio before and after use is compared. Table 1 shows the measurement results.

[0017]

[Table 1]

(Consideration of physical properties) In the embodiment, the elongation rate is 20 to 35% in the length direction, and the elongation is 5 to 13% in the width direction. Has also declined. On the other hand, in Comparative Example 1, the elongation rate in the length direction is large and the thickness is large, the residual strain rate is large, and the decrease in the elongation rate is large. In Comparative Example 2, the elongation rate in the length direction is the same as that of the example, but the elongation rate in the width direction is small and the thickness is large.

[Trial Test 1] As trial test 1, the above Example, Comparative Example 1 (high extensibility), and Comparative Example 2 (low extensibility) were performed on 12 feet of 12 active college male soccer players.
The ankle joint was fixed using the three types of bandages, and the fixing forces were compared. The comparison contents are ankle fixation device Telos SE
Before fixation, immediately after fixation, and after 30 minutes of exercise, the talus inclination angle was measured from a stress X-ray image obtained using the above method. The above exercises consisted of a combination of running, agility drill, and mini game in consideration of the game characteristics of the sucker, and the intensity was set so that the average heart rate during exercise was 150 to 160 beats / min. The fixing method was to repeatedly fix figure eight and hill lock. The change rate of the talus inclination angle was obtained by the following equation. Rate of change of talus inclination angle = {(talar inclination angle after exercise-talus inclination angle immediately after fixation) / talus inclination angle immediately after fixation} x 100 (How much is the talus inclination angle shifted after exercise compared to the initial fixation state) The smaller the value, the better the fixability.) Table 2 shows the measured values and the rate of change.

[0020]

[Table 2]

(Consideration of Results) As a result of the measurement of the talus inclination angle,
In the example, immediately after the fixation, the talus inclination angle after exercise is smaller than the talus inclination angles of Comparative Examples 1 and 2, and it can be seen that the fixing force is high in the examples. In particular, the talus inclination angle after exercise is significantly smaller in the example than in Comparative Examples 1 and 2. In the example, the bandage is hardly loosened even when exercising (the rate of change of the talus inclination angle is low), and the fixing force is low. Is maintained for a long time.

[Trial Test 2] As a trial test 2, the subjective evaluations of the players were compared by an experiment having the same contents as the trial test 1 described above. After performing fixation and exercise with three types of bandages on 12 subjects, it was determined which fixation method was the best in terms of fixation, persistence of fixation, difficulty in slipping, and adverse effects on exercise. investigated. In the survey, one of the three types of bandages considered to be the best was selected from the above-mentioned Examples, Comparative Examples 1 and 2, respectively. Table 3 shows the results of Test 2.

[0023]

[Table 3]

(Consideration of Results) As subjective evaluations of suckers, those of the embodiment are excellent in fixability, persistence of fixation, difficulty in slipping, etc., and are overwhelmingly high as they have no adverse effect on exercise. It turns out that it has been evaluated.

[Trial Test 3] A 33-month long-term trial of the above Example and Comparative Example 2 was carried out on 33 male and female soccer players from junior high school students to university students. Subjective evaluations in use were compared from the viewpoint of sexual continuity, difficulty in slipping, and whether or not there was any adverse effect on exercise. According to the subjective evaluation, 28 out of 33 persons overall evaluated that the example was superior to comparative example 2 and about 85% said that the example was superior. evaluated.

[0026]

According to the present invention, as described above, the fixing force is improved by making the length direction relatively low extensibility and giving the width direction a certain degree of extensibility. Therefore, it is possible to maintain the fixation during use by increasing the follow-up performance and reduce the deviation, and it can be effectively used for the prevention and treatment of trauma.
