Abstract
Description
Technical Field
[0001] The present invention relates to an arm sling supporter.
Background Art
[0002] Generally, when the arm, leg, etc. are injured, a support for protecting the injured part is used. For example, when the arm is injured due to a fracture, contusion, etc., a triangular bandage is used as the support. By using the triangular bandage, the movement of the elbow and shoulder is restricted, and the movement of the arm can be fixed.
[0003] The above triangular bandage is used in a manner of hanging the arm with the back of the neck as a fulcrum. Therefore, when using the triangular bandage, the load of the arm concentrates on the back of the neck, imposing a burden on the wearer. To avoid such concentration of the load, an arm sling supporter provided with a belt for fixing the arm to the trunk is known. Specifically, the arm sling supporter fixes one end side of the belt of the arm sling supporter near the elbow of the arm, arranges the belt to pass through the back and over the shoulder on the opposite side of the elbow to the front of the chest, and fixes the other end side of the belt near the wrist of the arm for use. Thereby, the wearer can support the weight of the arm so that it is borne by the shoulder.
Summary of the Invention
Problems to be Solved by the Invention
[0004] However, in the above arm sling supporter, the position for supporting the weight of the arm only changes from the back of the neck to the shoulder, and the concentration of the load on the arm cannot be suppressed, and there is still a problem that the burden on the wearer is not eliminated.
[0005] Therefore, an object of the present invention is to provide an arm sling supporter that disperses the load of the supported arm and reduces the burden on the wearer.
Means for Solving the Problems
[0006] The arm sling supporter according to the present invention includes a supporter body formed in a belt shape The aforementioned support body, The main body of the supporter has an arm insertion section at one end for inserting the arm and fixing the elbow, The other end of the aforementioned supporter body has a wrist fixing part for fixing the wrist, The arm insertion portion and the wrist fixing portion have an intermediate portion, The aforementioned intermediate portion includes an engaging portion that can engage with the wearer's clothing.
[0007] With this configuration, the intermediate portion is equipped with an engagement portion that can surface-engage with the wearer's clothing. As a result, when the wearer wears the arm sling support, the intermediate portion is positioned to conform to the wearer's clothing and surface-engage. This distributes the load of the arm to the area where the intermediate portion is in contact with the body, thereby reducing the burden on the wearer.
[0008] The aforementioned arm support is, The wrist fixing portion has an adjustment portion that allows the fixing position of the wrist to be adjusted in the longitudinal direction of the support body.
[0009] With this configuration, the wrist support section has an adjustment section that allows the wrist to be adjusted in the longitudinal direction of the support body, so that the wearer can adjust the wrist position to the height that causes the least strain when wearing the arm support, thereby further reducing the burden on the wearer.
[0010] The aforementioned arm support is, Equipped with additional support belts, The arm insertion portion has a first auxiliary belt fixing portion for fixing one end of the auxiliary belt, The aforementioned intermediate portion has a second auxiliary belt fixing portion for fixing the other end of the auxiliary belt.
[0011] With this configuration, the arm insertion portion has a first auxiliary belt fixing portion for fixing one end of the auxiliary belt, and the intermediate portion has a second auxiliary belt fixing portion for fixing the other end of the auxiliary belt. As a result, the auxiliary belt can connect the intermediate portion, which is located on the wearer's back when worn, with the arm insertion portion that fixes the wearer's elbow, while in contact with the wearer. This distributes the load on the arm even in the area where the auxiliary belt is in contact with the body, further reducing the burden on the wearer.
[0012] The aforementioned arm support is, The arm insertion portion has a first auxiliary belt fixing reinforcement portion, The aforementioned intermediate portion has a second auxiliary belt fixing reinforcement portion, One end of the auxiliary belt can be sandwiched between the first auxiliary belt fixing portion and the first auxiliary belt fixing reinforcement portion and fixed to the supporter body. The other end of the auxiliary belt can be secured to the supporter body by being sandwiched between the second auxiliary belt fixing portion and the second auxiliary belt fixing reinforcement portion.
[0013] With this configuration, one end of the auxiliary belt can be secured to the supporter body by being sandwiched between the first auxiliary belt fixing part and the first auxiliary belt fixing reinforcement part, and the other end of the auxiliary belt can be secured to the supporter body by being sandwiched between the second auxiliary belt fixing part and the second auxiliary belt fixing reinforcement part. As a result, the auxiliary belt is more firmly attached to the supporter body, making it less likely for the auxiliary belt to come off the supporter body while being worn. This further reduces the burden on the wearer. [Effects of the Invention]

[0019] As shown in Figures 1 and 2, the supporter body 2 comprises a base material 20 formed in a strip shape and a strip-shaped hook-and-loop fastener member 21 laminated in the thickness direction to the base material 20.
[0020] The male hook-and-loop fastener member 21 has a male hook-and-loop fastener across its entire surface. One end of the male hook-and-loop fastener member 21 in the longitudinal direction is positioned at one end of the base material 20 in the longitudinal direction. That is, the one end of the male hook-and-loop fastener member 21 in the longitudinal direction and the one end of the base material 20 in the longitudinal direction are in approximately the same position. The other end of the male hook-and-loop fastener member 21 in the longitudinal direction is positioned around the other end of the base material 20 in the longitudinal direction. That is, the other end of the male hook-and-loop fastener member 21 in the longitudinal direction is located closer to one end than the other end of the base material 20 in the longitudinal direction. Therefore, the length of the male hook-and-loop fastener member 21 in the longitudinal direction is shorter than the length of the base material 20 in the longitudinal direction. Both ends of the male hook-and-loop fastener member 21 in the longitudinal direction and both ends in the width direction are sewn to the base material 20.

[0071] The ratio of sea component to island component (sea:island) in the aforementioned sea-island composite fiber is preferably 40:60 to 5:95, and more preferably 30:70 to 10:90.
[0072] The aforementioned sea-island composite fiber can be easily manufactured, for example, by the following method: melt spinning is performed using the sea component polymer and the island component polymer. Any spinneret can be used for melt spinning, such as one having a group of hollow pins or a group of micropores for forming the island component. The extruded sea-island composite fiber is solidified by cooling air and, after melt spinning, is wound up at a speed of 400 m / min to 6000 m / min. This yields an undrawn yarn. The undrawn yarn may be subjected to a separate drawing process to become a composite fiber having desired strength, elongation, and heat shrinkage characteristics. Alternatively, after melt spinning the sea-island composite fiber, it may be taken up to a roller at a constant speed without being wound up, and then wound up after passing through a drawing process.
[0073] The single-fiber fineness of the aforementioned sea-island type composite fiber is preferably 0.5 dtex or more and 10.0 dtex or less.

[0077] A fabric is obtained by weaving the sea-island type composite fiber and filament yarn B. The sea-island type composite fiber is preferably woven so as to be exposed on the surface of the fabric. The sea-island type composite fiber and filament yarn B may be included in the woven or knitted fabric as a blended yarn. A knitted or woven fabric may be woven by interweaving or interknitting the polyester filament yarn A and the filament yarn B. The total fineness ratio of the sea-island type composite fiber and filament yarn B is preferably 90:10 to 50:50.
[0078] By treating the aforementioned fabric with an alkaline aqueous solution and dissolving and removing the marine components of the sea-island type composite fiber with the alkaline aqueous solution, the sea-island type composite fiber filament yarn is converted into polyester filament yarn A with a single fiber diameter of 10 nm to 1000 nm, thereby obtaining a hook-and-loop fastener. In this case, the conditions for the alkaline aqueous solution treatment are to use a 3% to 4% NaOH aqueous solution and treat at a temperature of 55°C to 65°C.
[0079] The material of the female hook-and-loop fastener is not particularly limited, but may be, for example, a fabric having a pile.
[0080] The intermediate portion 27 is equipped with an engaging portion 271 that can surface-engage with the wearer's clothing, so that the intermediate portion 27 is positioned to conform to the wearer's clothing and surface-engage. In other words, the intermediate portion 27 can be made to fit snugly against the wearer's clothing. As a result, the load originating from the arm is distributed across the entire intermediate portion 27 over a wider area that is in contact with the body. This reduces the burden on the wearer.
[0081] In the arm support 1, the arm insertion portion 26 supports the wearer's elbow, and the wrist fixing portion 25 fixes the wearer's wrist, so that when worn, the intermediate portion 27 comes into contact with the wearer's back, the shoulder opposite the elbow, and the chest opposite the elbow. As a result, the load of the arm is distributed across the entire intermediate portion 27 to a wider area that comes into contact with the body. This further reduces the burden on the wearer.
[0082] The arm support 1 is equipped with an auxiliary belt 3, and the arm insertion portion 26 has a first auxiliary belt fixing portion 262 for fixing one end of the auxiliary belt 3, and the intermediate portion 27 has a second auxiliary belt fixing portion 272 for fixing the other end of the auxiliary belt 3. As a result, the auxiliary belt 3 can connect the intermediate portion 27, which is located on the back side of the wearer when worn, and the arm insertion portion 26, which fixes the wearer's elbow, via the front of the wearer. In other words, the auxiliary belt 3 can come into contact with the front of the wearer. This distributes the load on the arm even in the area where the auxiliary belt 3 is in contact with the body, further reducing the burden on the wearer.
[0083] The engagement portion 271M has a hook-and-loop fastener, which improves the adhesion between the intermediate portion 27 and the wearer's clothing, allowing the intermediate portion 27 to be more firmly secured to the wearer's clothing. As a result, a wider area of the intermediate portion 27 comes into contact with the body, so the load on the arm is distributed more evenly across the entire intermediate portion 27, further reducing the burden on the wearer.
[0084] The wrist support portion 25 has an adjustment portion 251 that allows the wrist position to be adjusted in the longitudinal direction of the supporter body 2. This allows the wearer to adjust the wrist position to the height that causes the least strain when wearing the arm sling supporter 1, thereby further reducing the burden on the wearer.
[0085] The adjustment section 251 has a female hook-and-loop fastener in the first adjustment area 252F and a male hook-and-loop fastener in the second adjustment area 253M, making it easier to adjust the position of the wrist.
[0086] The elbow fixation part 264M has a hook-and-loop fastener, which allows it to be attached to the wearer's clothing, a bandage wrapped around the wearer's arm, etc. As a result, the wearer's elbow is fixed by the elbow fixation part 264M, which prevents the elbow fixation position from shifting between the wearer's elbow and wrist.
[0087] Since the arm insertion portion 26 has a first auxiliary belt fixing portion 262 and a first auxiliary belt fixing reinforcement portion 263, and the intermediate portion 27 has a second auxiliary belt fixing portion 272 and a second auxiliary belt fixing reinforcement portion 273, the auxiliary belt 3 is firmly attached to the supporter body 2, making it less likely for the auxiliary belt 3 to come off the supporter body 2 while being worn.
[0088] Because the auxiliary belt 3 has a first supporter body fixing part 32, a second supporter body fixing part 33, a first supporter body fixing reinforcement part 34, and a second supporter body fixing reinforcement part 35, the auxiliary belt 3 is firmly attached to the supporter body 2, making it less likely for the auxiliary belt 3 to come off the supporter body 2 while being worn.
[0089] The first auxiliary belt fixing reinforcement part 263M, the second auxiliary belt fixing part 272M, the first supporter body fixing part 32M, and the second supporter body fixing reinforcement part 35M have male hook-and-loop fasteners, while the first auxiliary belt fixing part 262F, the second auxiliary belt fixing reinforcement part 273F, the first supporter body fixing reinforcement part 34F, and the second supporter body fixing part 33F have female hook-and-loop fasteners. As a result, the auxiliary belt 3 is more firmly attached to the supporter body 2, making it less likely for the auxiliary belt 3 to come off the supporter body 2 during wear.
[0090] The auxiliary belt 3 has an engagement auxiliary portion 36 between the first supporter body fixing portion 32 and the second supporter body fixing reinforcement portion 35 that engages surface with the wearer's clothing. The engagement auxiliary portion 36 is positioned to conform to the wearer's clothing and engages surface with it. As a result, the load of the arm is distributed to the area of the engagement auxiliary portion 36 that is in contact with the body, further reducing the burden on the wearer.
[0091] The engagement support portion 36M has a hook-and-loop fastener, which improves the adhesion between the engagement support portion 36M and the wearer's clothing, allowing the engagement support portion 36M to be more firmly secured to the wearer's clothing. As a result, a wider area of the engagement support portion 36M comes into contact with the body, so the load on the arm is distributed across the entire engagement support portion 36M, further reducing the burden on the wearer.
[0092] The exposure of the polyester filament yarn A on the surface of the male hook-and-loop fastener improves the adhesion between the male hook-and-loop fastener and the wearer's clothing, female hook-and-loop fastener, etc. For example, when the male and female hook-and-loop fasteners engage surface-to-surface, the fibers in the pile-like fabric of the female hook-and-loop fastener become entangled with the polyester filament yarn A exposed from the surface of the male hook-and-loop fastener, resulting in surface engagement between the two fasteners and improved adhesion.
[0093] Furthermore, the arm support according to the present invention is not limited to the embodiments described above.
[0094] The material of the base material and auxiliary belt base material is not particularly limited and may be a fabric such as knitted fabric or woven fabric.
[0095] The shape of the wrist fixing portion forming member, the arm insertion portion forming member, and the intermediate portion forming member is not limited to a strip shape, but may be circular, rectangular, or other polygonal shapes, for example.
[0096] The arm insertion portion forming member may be positioned on the inner side in the longitudinal direction of the arm insertion portion, or on the outer side in the longitudinal direction. If the arm insertion portion forming member is positioned on the inner side in the longitudinal direction of the arm insertion portion, the first auxiliary belt fixing reinforcement portion may be provided on the outer side in the longitudinal direction of the arm insertion portion. If the arm insertion portion forming member is positioned on the outer side in the longitudinal direction of the arm insertion portion, the first auxiliary belt fixing reinforcement portion may be provided on either side in the width direction of the arm insertion portion.
[0097] The intermediate portion forming member may be positioned approximately at the center in the longitudinal direction of the intermediate portion, or at the end in the longitudinal direction. [Explanation of symbols]
