Description

The present invention relates to a shoulder joint fixing device for maintaining a desired treatment limb position in the treatment of various shoulder joint disorders mainly involving subluxation and dislocation of the shoulder joint.

Shoulder joint disorders are common, and the disorders may be addictive or repetitive, so they are strongly fixed in the treatment position for several weeks, both conservatively and openly. It is done. As a fixing method that is often used, the forearm is bent by 90 degrees, the forearm is inserted into the arm bag or the forearm holder, and the forearm is attached by a suspension belt attached between both ends of the arm bag or the forearm holder. Fastening device using so-called arm suspension that fixes the arm in close contact with the trunk (see, for example, Patent Document 1 and Patent Document 2), a belt that is based on arm suspension fixing such as a sling, and has a high adhesion between the upper limb and the trunk An internal rotation fixing device (for example, see Patent Document 3), a fixing device that uses a forearm suspension belt and sandwiches an armpit pad under the armpit so that the shoulder joint abduction angle can be adjusted to a desired range (for example, Patent Document 4), a rigid brace that combines a hinge having a joint at each joint of the upper limb (see, for example, Patent Document 5), a hand holder that supports the hand and the forearm, and a neck bracket connected to the hand holder. G, a waist belt that has a waist belt that fixes the upper arm to the trunk, and that can fix the shoulder joint in a slight external rotation (see Patent Document 6, for example), a shoulder belt, an abdominal belt, and both belts There is a method of using a belt for shoulder joint protection (for example, see Patent Document 7) used for reduction and prevention of subluxation of the shoulder joint using a belt attached to the shoulder joint. Further, a cushion bag having a substantially right triangle shape in cross-sectional view that fits between the upper limb and the body side iliac crest, a belt body that winds around the body and supports the cushion bag, and an upper limb placed on the cushion body. And a shoulder joint orthosis that holds shoulder joint abduction (for example, see Patent Document 8). Furthermore, when the above-described fixing method and stability of fixation are not satisfactory, a so-called arm suspension (see, for example, Patent Document 1 and Patent Document 2) and a device for holding an abduction of a shoulder joint (for example, in a medical field) (See Patent Document 8).

Although each of the above-mentioned fixing devices is selected according to the degree of each obstacle, nonetheless, the fixing method using these fixing devices has not been verified based on medical data. There is a high possibility that it will lead to re-disability and subsequent functional failure of the affected area. In recent studies, each tissue at the damaged site has been reduced to an anatomically conservative or open blood normal position, its limbs fixed and held, and further moderately loaded, It has become clear that each tissue is optimally repaired (remodeled or repaired). Based on these basic studies, some clinical studies have given similar results in shoulder joint disorders. In shoulder dislocations, where shoulder joint dislocations are frequently repetitive, the choice of fixation method was very difficult, but after each tissue at the damaged site was reduced to an anatomically normal position. It has become clear that holding the shoulder joint in a slight external rotation is effective in maintaining the position of each tissue normally and suppressing the recurrence rate of shoulder dislocation to less than 1/3. However, when trying to cope with this method with various devices so far, it is not possible to achieve this fixed limb position with a device that suspends arms or fixes internal rotation, and it is possible to use various devices with other devices. Although it has the characteristics, the adjustment until the required angle is set is very complicated, and a lot of belts and rigid materials must be used to fix in the predetermined limb position A sense of restraint is very strong. The same applies not only to shoulder joint dislocation disorders but also to shoulder joint disorders that may require similar fixation.

An object of the present invention is to easily fix a shoulder joint to a limb position in which the normal positional relationship is maintained after the shoulder joint is reduced to an anatomically normal position at the time of shoulder joint failure, Shoulder joint orthosis equipped with means capable of maintaining the limb position for a long time and at the same time ensuring more reliable adhesion of damaged tissue of the shoulder joint and ensuring a compressive force that maintains an anatomically normal positional relationship Is to provide.

In order to solve the above-described problems, according to the present invention, a pad having a portion corresponding to the periphery of the trunk, a torso belt for fixing the pad to the periphery of the trunk, and fixing the affected forearm to the pad And a shoulder belt for applying a compression force to the affected shoulder joint.

  Further, according to the present invention, a pad having a portion corresponding to the periphery of the trunk, a torso belt for fixing the pad to the periphery of the trunk, and a forearm fixing portion for fixing the affected forearm to the pad, And an elbow belt that suppresses the internal and external rotation of the shoulder joint from a predetermined fixed position by the action of the pulling force in the shoulder joint external rotation direction and the compression force in the trunk direction on the affected forearm portion.

Furthermore, according to the present invention, a pad having a portion corresponding to the periphery of the trunk, a torso belt for fixing the pad to the periphery of the trunk, a forearm fixing portion for fixing the affected forearm to the pad, A shoulder belt for applying a compression force to the shoulder joint on the affected side, and a pulling force in the external rotation direction of the shoulder joint and a compression force in the trunk direction against the forearm portion on the affected side from the predetermined fixed position of the shoulder joint. You may make it provide the elbow belt which suppresses internal / external rotation movement.

According to the shoulder joint fixing device of the present invention, the pad is securely fixed around the trunk by the torso belt, and the forearm is fixed to the pad while holding the predetermined limb position by the forearm fixing portion. It is securely held at the external rotation position. Furthermore, an appropriate compression force is applied to the shoulder joint by the shoulder belt, and as a result, the degree of adhesion between the soft tissue and the bone tissue of the shoulder joint is increased. The rate can be reduced.

For example, if the contraindicated movement direction of the shoulder joint is an internal rotation direction due to a disorder, if the internal rotation direction force is generated for some reason during wearing for a long time, the shoulder joint is Since a pulling force is applied in the external rotation direction, a force resisting the contraindicated movement direction, i.e., the force generated in the internal rotation direction, acts on the forearm, and at the same time, it can also apply a compression force in the trunk direction, thus dragging in the trunk direction This increases the frictional force between the torso belt and trunk and prevents internal / external rotation from a predetermined shoulder joint angle, improving the stability of the shoulder joint and more reliable recovery of shoulder joint damage. Can be expected.

  Furthermore, since the shoulder joint fixing device of the present invention can be configured to be light and small, and the wearing condition can be adjusted, the sense of restraint in daily life is greatly reduced.

  According to the present invention, by adding a shoulder belt or an elbow belt, it is possible to improve the retainability and fit as an orthosis.

  The pad is preferably composed of a core material and a cover material covering the core material. The core material is formed of a material that can maintain its shape, that is, a material that is hard to be deformed even when subjected to a load on the upper limb. For example, it is a foamed material such as polystyrene foam, urethane foam, or polyethylene foam. The shape of the pad is a curved side formed by hollowing out a circular or elliptical shape to fit a polygonal shape such as a triangular prism shape or a quadrangular prism shape having a thickness about the width of the forearm portion, and a forearm And a forearm fixing side having a length substantially equal to 1/2 of the forearm to the forearm length and a substantially straight forearm fixing side. Further, by forming a side having a small length between the curved side and the forearm fixed side, a slight abduction of about 5 to 30 degrees can be given to the upper limb. If these small length sides having different lengths are formed on both sides of the curved side, two types of light abduction angles can be obtained by inverting the pad. As the pad, in addition to the above-mentioned pad, a pad used in the prior art may be used, or a fixing material combining a resin and a granular material may be used as the pad.

The cover material covers a part or the entire surface of the core material and is made of a material with low stretchability, and a hook-and-loop fastener is sewn according to the running direction of the belt so that the belts can be locked. A fabric having looped or hook-like raised hairs can be used. Also, in order to improve the followability with the trunk, the surface of the core or cover material that touches the trunk is deformed by receiving a soft foam, that is, a load, and the shape of the substance is maintained for a while after unloading It is also possible to combine a cushioning material such as a low rebound resilience foam. By such a combination, the fit to the body part is supplemented by a cushioning material, and the fixability functions to hold a predetermined fixed position of the upper limb even when the body is twisted by a hard foam, for example. It is obtained by doing.

The forearm fixing side is approximately the same length as the forearm length of the pad, and a forearm fixing part is provided. This forearm fixing part fixes the forearm such as a bag-like forearm bag that can fit the forearm, one or more belts, etc. Provides a means to do. The forearm bag is made of low-stretch fabric, the basic shape is a rectangle or a deformed rectangle, and a pair of adjacent short and long sides are closed by sewing etc., and the forearm is a forearm bag A belt is provided to hold the belt when it is inserted into the belt. This holding belt is also provided with a fastener such as a hook-and-loop fastener at the tip so that the tightening force is adjusted at the time of attachment. The forearm bag may be installed on the pad even if the forearm bag is fixed by sewing, or may be removed by a hook-and-loop fastener or the like.

The torso belt is fixed to the curved side of the pad by sewing, or is detachably joined by a hook-and-loop fastener and a fastener, its length is slightly longer than the trunk circumference, and its width is joined to the pad Advantageously, the portion has a maximum width, and this portion is as wide or larger than the pad. The torso belt also has fasteners such as hook-and-loop fasteners and buckles to fix it when wrapped around the trunk, so that the tightening force can be finely adjusted. It is desirable to use a highly breathable and low stretch fabric or a combination of a low stretch fabric and a highly stretchable fabric for the torso belt. It is preferable to use a material that does not easily sag, and depending on its strength, it is possible to reduce the tightening strength of the body belt. Further, it is advantageous to provide a material having a frictional force enough to resist the movement of the shoulder joint in the internal rotation direction on the inner side of the body belt, for example, a material having a certain raising direction. You can also. In addition, the body belt can be provided with a hook-and-loop fastener, a buckle, and a tongue for joining the shoulder belt and the elbow belt so that the shoulder belt and the elbow belt can be attached and detached. When it is necessary to give freedom to the angle of extension and bending of the elbow joint, the waist belt is not fixed to the pad over the entire facing surface, but only the upper side or the lower side of the body belt facing the pad is padded. The other side, that is, both sides, the lower side or the upper side is attached so as to be separable with a fastener, etc., so that the angle between the trunk axis and the pad can be adjusted within a certain range, A desired wearing limb position of the elbow joint may be obtained. Alternatively, the pad and the body belt may be hinged only on both sides so that the angle between the pad and the body belt can be adjusted by rotating the hinge.

The shoulder belt keeps the degree of adhesion between the soft tissue of the shoulder joint and the humerus constant even if a slight movement (about 10 degrees) occurs in the shoulder joint for smooth daily life. Even if tissue deformation due to edema or hematoma occurs, the shoulder joint does not loosen, and it also prevents tissue deformation due to edema or hematoma, so that proper maintenance can be performed. It extends from the front of the trunk through the shoulder joint on the obstacle side in the diagonal direction on the back and is connected to the waist belt. In this case, in the wearing state, the shoulder belt travels from the front of the trunk through the shoulder joint to the back of the trunk and passes through the shoulder joint to the trunk centerline side from the axis parallel to the trunk centerline. It is advantageous to be connected to the waist belt at the offset position. In addition, by connecting the shoulder belt to the waist belt on the front side and the back side in this way, there is an advantage that compression can be applied at various positions of the shoulder joint portion. The distance to the trunk centerline is determined according to the symptoms. In addition, if the shoulder belt has an angle between the running line at the front of the trunk and the running line at the back of the trunk, the shoulder belt fits into the complicated curved shape of the shoulder joint and prevents the belt from being compressed. It is advantageous in that it can. An appropriate value for this angle is selected according to the symptom. The joining position on the back side of the shoulder belt is preferably a portion slightly closer to the side opposite to the affected side than the center of the back side of the torso belt in the worn state. Depending on the direction of load applied to each tissue of each shoulder joint disorder, there are cases where the shoulder belt is installed at a position slightly further away from the affected side from the trunk center line on the front or back of the trunk. . It is preferable that the shoulder belt has a length adjusting mechanism using a cocan or a hook-and-loop fastener in a part thereof. The shoulder belt may be provided with a shoulder pad using a soft foam having a high cushioning property that can cover part or all of the front and rear of the shoulder joint. The shoulder belt can be formed of non-stretchable and stretchable materials, or a combination of both. The shoulder belt is joined to the body belt at least one end by a buckle, a hook-and-loop fastener or the like, and the other end is fixed by sewing or can be attached or detached by a hook-and-loop fastener or the like.

The elbow belt is provided in order to suppress the internal and external rotation of the shoulder joint from a predetermined fixing position. The elbow belt is attached between the forearm fixing portion and the torso belt or pad, and at least one end is a hook-and-loop fastener or the like. It is advantageous that the fixing position can be adjusted by the means described above. If part or all of the belt is stretchable, both ends can be sewn. In particular, it is preferable in terms of mounting operation that one end is fixed to the waist belt by means such as sewing, and the other end is configured to be engageable with the forearm fixing portion with a hook-and-loop fastener. The elbow belt can be formed of non-stretchable and stretchable materials, or a combination of both.

  Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a perspective view of a first embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a pad, which is hollowed out from a quadrangular columnar shape along one ridgeline to form a curved surface 2 along the periphery of the trunk to be attached. In this case, if a distance p exists between at least one end 3 of the curved surface 2 and the adjacent surface 4, it is possible to cope with slight abduction of the shoulder joint using this distance p. . This can be formed by leaving some of the end when hollowing out of a square column. In the illustrated embodiment, a similar distance q exists at the other end of the curved surface 2. The pad 1 is configured so that a core material formed of polystyrene foam is covered with a cover material made of tricot fabric using nylon fibers.

  A torso belt 11 is sewn to the curved surface 2 of the pad 1, and the torso belt 11 fixes the pad 1 to the trunk. If the portion facing the curved surface 2 of the torso belt 11 is slightly wider than the other portions and is formed in a mesh shape, the contact with the trunk is soft and breathable, and further, the pad hangs down due to elbow flexion. This can be advantageously prevented by the rigidity in the width direction of the waist belt. Fixing belts 13 and 14 are fixed to one end 12 of the body belt 11, and paired hook and loop fasteners 15 and 16 are provided on the front side of each belt. Further, belt insertion cogs 18 and 19 are attached to the other end 17 of the body belt 11. The body belt 11 is made of double raschel fabric using polyester fiber and nylon fiber.

  A forearm fixing portion 21 is provided on the side surface of the surface 4 adjacent to the curved surface 2 of the pad 1. The forearm fixing portion 21 includes a forearm bag 22 fixed to the side surface of the pad by sewing, and forearm belts 23 and 24 having one end fixed to the forearm bag 22. Both sides are sewn at the portion 25, and the forearm is stably accommodated in the bag by inserting the forearm from above. The front end portion 25 may be coupled to both side surfaces with a belt or a string. Hook fasteners 26 and 27 are provided on the inner ends of the front arm belts 23 and 24, respectively. The forearm bag 22 is made of double raschel fabric using polyester fiber and nylon fiber, and the forearm belts 23 and 24 are made of woven belt using polypropylene fiber. In the figure, the forearm bag is open at the front and upper part, but the rear part may also be opened so that the position of the forearm in the forearm bag can be adjusted back and forth. Further, the forearm bag can be attached to and detached from the side surface of the pad with a hook-and-loop fastener or the like without being fixed to the pad by sewing or the like, and the mounting position of the forearm bag with respect to the pad can be made variable.

  Further, one end of a shoulder belt 31 is fixed to one portion of the back portion of the body belt 11, and a buckle male part 32 is attached to the other end of the shoulder belt 31, and the male part 32 has two grooves 33 and 34. The front end of the shoulder belt 31 is sequentially inserted into both grooves so as to be folded. By changing the folding position, the length when the shoulder belt is worn can be adjusted. The opposite buckle female part 35 with respect to the buckle male part 32 is fixed in the vicinity of the end of the curved surface 2 of the trunk belt 11 and is engaged with each other by inserting the buckle male part 32 into the buckle female part 35. It is advantageous that the attachment portion of the shoulder belt 31 to the back surface of the torso belt 11 is slightly shifted from the center of the back surface to the opposite side of the affected side. An angle can be given to the back side, and a compression force can be applied to the shoulder joint from the front side. The shoulder belt 31 is a woven belt using polypropylene fibers.

  FIG. 2 is a perspective view of the second embodiment of the present invention, and the same reference numerals are given to the same parts as those of the embodiment of FIG. This embodiment is different from the embodiment of FIG. 1 in that there is no shoulder belt and an elbow belt is provided. That is, each configuration of the pad 1, the waist belt 11 and the forearm fixing portion 21 is exactly the same as the embodiment of FIG. In this embodiment, one end of an elbow belt 41 is fixed to the rear part of the torso belt 11. The elbow belt 41 extends substantially along the longitudinal direction of the torso belt 11 and the forearm bag 22. 43 is attached. On the other hand, a hook-and-loop fastener 28 is fixed to the outer side surface of the forearm bag 22, and the hook-and-loop fastener 43 of the elbow belt 41 is attached to the forearm bag 22 at a position where the force with which the elbow belt 41 pulls the forearm fixing portion 21 backward is a predetermined value. The hook-and-loop fastener 28 is engaged.

  The third embodiment of the present invention includes both the shoulder belt of FIG. 1 and the elbow belt of FIG. That is, the elbow belt 41 shown in FIG. 2 is further added to the pad 1, the waist belt 11, the forearm fixing portion 21 and the shoulder belt 31 of the embodiment shown in FIG. As shown in

  In the first to third embodiments, the pad 1 and the torso belt 11, the pad 1 and the forearm bag 22, and the shoulder belt 31 and the torso belt 11 can be joined using a hook-and-loop fastener. This can further increase individual correspondence.

  Next, the mounting method will be described with reference to FIG. 3 is a front view, b is a right side view, c is a rear view, and d is a left side view in a state in which the shoulder joint fixing device of the third embodiment is mounted, and is equivalent to the embodiment of FIGS. The same reference numerals are given to the portions. First, with the belt 13 and 14 of the waist belt 11 and the belt insertion rings 17 and 18 disengaged, the waist belt 11 is wound around the trunk, and the forearm fixing portion 21 is the affected side of the shoulder joint (in the example shown in the figure). The belts 13 and 14 are respectively inserted into the rings 18 and 19 at positions where they come to the right shoulder (see FIG. 3a), and are folded back so as to be in a desired tightening state. Are respectively engaged and fixed. Next, the forearm is inserted into the forearm bag 22 from above and tightened with the forearm belts 23 and 24, and the surface fasteners 26 and 27 are engaged and fixed to the forearm bag 22 and the surface of the pad 1. Further, the shoulder belt 31 is extended from the back surface of the torso belt 11 so as to pass down over the shoulder on the affected side and to the front surface, and the buckle male part 32 is inserted into and engaged with the buckle female part 35. In this case, the length of the shoulder belt 31 is adjusted in advance so that an appropriate compression force is applied to the shoulder joint portion by changing the position of the shoulder belt 31 with respect to the grooves 33 and 34 of the buckle male portion 32 in advance. Further, the elbow belt 41 is rotated forward from the rear portion of the torso belt 11 along the torso belt, and when an external force is applied in the internal rotation direction from a predetermined external rotation position of the upper limb, a position at which a backward tensile force can be applied to prevent the external force from acting. Then, the hook-and-loop fastener 43 is attached to the hook-and-loop fastener 28 of the forearm bag 22. The mounting state shown in FIG. 3 is obtained by the above operation process. In the case of the bracelet with only the shoulder belt shown in FIG. 1 and without the elbow belt, there is no elbow belt wearing operation, and in the case of the brace with only the elbow belt shown in FIG. It goes without saying that there is no such thing.

  In the first and third embodiments described above, one end of the shoulder belt 31 is connected to the front side of the waist belt 11 by the buckle male portion 32 and the buckle female portion 35, and the other end is connected to the back side of the waist belt 11. However, as is apparent from FIGS. 3a and 3c, the shoulder belt 31 passes through the shoulder joint portion and is positioned closer to the trunk center line 51 than the axis 52 parallel to the trunk center line 51. It is connected. Further, as can be seen from the figure, the travel line on the front side of the shoulder belt 31 and the travel line on the back side are not parallel but have an angle, that is, the distance from the axis 52 to the trunk centerline 51 side is the shoulder belt. The difference between the front side and the back side of 31 is advantageous in that it can fit into the complicated curved surface shape of the shoulder joint and prevent the belt from being compressed.

  In the above-mentioned wearing state, the external rotation angle of the upper limb can be set by the mounting position of the side surface 4 adjacent to the curved surface 2 of the pad 1 with respect to the trunk, and the curved surface 2 of the pad 1 and the forearm fixing portion The abduction angle of the upper limb is obtained by the small distance p existing between The pad 1 is securely fixed around the trunk by the torso belt 11, and the forearm is stably held by the forearm fixing portion 21, so that the upper limb is fixedly held at a predetermined external rotation and abduction. As a result, the soft tissue and bone tissue of the damaged shoulder joint is held in an anatomically normal position. Further, by wearing the shoulder belt 31, it is expected that an appropriate compression force is continuously applied to the shoulder joint region, preventing the recurrence of shoulder joint disorders and improving recovery. Also, by wearing the elbow belt 41, the normal limb position that should have been held by the pad 1, the torso belt 11 and the forearm fixing part 21 is going to fail due to contraindicated external forces such as internal rotation. In some cases, the forearm fixing portion 21 is pulled backward by the elbow belt 41, and a compressive force in the trunk direction is generated, and the movement from the original normal position can be prevented or returned by this force. In addition, the wearer himself / herself can exercise the consciousness of returning the upper limb to the normal position by sensing the pulling force to the rear and the pressing force to the trunk. Note that when there is no need for abduction, there is no need for a small distance portion provided between the curved surface of the pad and the forearm fixing portion.

  In the present invention, it is usually most preferable to treat the elbow joint at 90 ° for treatment, but if it is necessary to make another angle, the side surface of the pad should have a shape corresponding to an angle other than 90 °. The position of the pad relative to the trunk can be adjusted, and the angle of the pad extending outward from the trunk can be changed. In addition, it is not fixed to a fixed angle depending on a disorder | damage | failure, A certain movable range (for example, 70-90 degrees) can be provided, and it can also be made to change an angle according to progress of a healing process.

  If the pad is symmetrically shaped except for the curved surface, and the small distances p and q existing between the curved surface and the adjacent surfaces are different, the pad is inverted and attached to the trunk. Two types of abduction angles can be obtained. In this case, the forearm fixing portion, the shoulder belt, and the elbow belt must be configured to be detachable, and it is necessary to reverse the pad and change the mounting position of the forearm fixing portion, the shoulder belt, and the elbow belt.

  FIG. 4 is a perspective view of a fourth embodiment of the present invention, and the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals. This embodiment is different from the first to third embodiments in that the pad 1 is provided with a hook-and-loop fastener 110 with respect to the body belt 11, and the forearm bag 22 of the forearm fixing portion is provided with a hook-and-loop fastener 29 with respect to the pad 1 and the back side of the shoulder belt 31. The fixing end of the elbow belt 41 to the trunk belt 11 is detachable by the hook-and-loop fastener 44 with respect to the trunk belt 11 with the hook-and-loop fastener 36 at the end and the hook-and-loop fastener 37 at the abdomen side end. That is, the pad, the waist belt, the shoulder belt, and the elbow belt can be attached to and detached from each other with a hook-and-loop fastener. Since each element can be separated in this way, each element can be selected and used in accordance with the wearer's physical characteristics and symptoms.

  FIG. 5 is a perspective view of a fifth embodiment of the present invention, and the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals. This embodiment is different from the first to third embodiments in that the waist belt 11 is narrower than the thickness of the pad 1, and both ends thereof are not connected by a hook-and-loop fastener, but the engagement between the buckle male part 112 and the buckle female part 113. The shoulder pad 38 is provided at a position corresponding to the shoulder joint of the shoulder belt 31. Although the width of the body belt 11 is narrow, the stability is inferior to that of the wide body belt of the previous embodiment, but there is an advantage that the weight is reduced and the feeling of pressure is reduced. Also, the shoulder pad 38 improves the fit to the shoulder joint, and has an effect of applying pressure over a wide range and preventing the occurrence of abnormal local bias.

  FIG. 6 is a perspective view of a sixth embodiment of the present invention, and the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals. This embodiment is different from the first to third embodiments in that the pad 1 is cut so that one side 5 is larger than the pads shown in FIGS. 1 and 2 and is formed so as to follow the forearm fixing portion. This is the point that it can be coupled by the hook-and-loop fasteners 114 and 115 provided at both ends of the body belt without providing the fixing belt. By reducing the volume of the pad in this way, stability and buffering are somewhat reduced, but it can be applied when the patient in the recovery phase does not require much stability and the burden on the patient is reduced. . Further, connecting both ends of the body belt directly with a hook-and-loop fastener leads to ease of mounting operation.

  FIG. 7 is a perspective view of a seventh embodiment of the present invention, and the same reference numerals are given to the same parts as those in FIGS. In this embodiment, the opposite side 6 of the pad 1 is cut to reduce the weight. The burden on the patient is reduced because the pad is lighter.

  FIG. 8 is a perspective view of an eighth embodiment of the present invention, and the same reference numerals are given to the same parts as those in FIGS. In this embodiment, the mechanism for holding the forearm of the forearm fixing portion 21 is not a bag, but is formed by forearm fixing belts 210 and 211 attached to the side surface of the pad 1, and these belts are wound around the forearm. The forearm is fixed to the pad by engaging the pad fasteners 212 and 213 on the pad 1. The forearm can be securely held with good fit regardless of the thickness of the patient's forearm. Although only the pad and the forearm fixing part are shown in the figure, any of the above-described embodiments can be used for the other waist belt, shoulder belt, and elbow belt.

  FIG. 9 is a perspective view of the ninth embodiment of the present invention, and the same reference numerals are given to the same parts as those of the above-described embodiments. In this embodiment, the forearm fixing portion 21 is provided not on the side surface of the pad but on the upper surface 7 of the pad 1. In this case, since the pad 1 is located slightly on the side of the human body, that is, below the side, it is preferably formed in a vertically long shape. By holding the forearm on the upper surface of the pad in this way and using the shoulder belt and elbow belt, the forearm can be stably held and repaired especially for symptoms that need to be held for a long period of time. . The forearm fixing portion 21 can be fixed to the upper surface of the pad 1 by sewing, can be detachably attached with a hook-and-loop fastener, or can be provided by various methods.

  FIG. 10 is a perspective view of a tenth embodiment of the present invention, and the same reference numerals are given to the same parts as those of the above-described embodiments. In this embodiment, a shoulder belt 39 from the body belt 11 to the healthy side is provided. One end of the shoulder belt 39 is connected to the front portion of the waist belt 11 and is connected to the shoulder belt 31 on the affected side through a buckle female portion 310 having a length adjusting function and a buckle male portion 311 so as to be connected to the back belt belt. 11, both shoulder belts 31, 39 are formed in a Y or V shape on the back. In this case, both shoulder belts 31 and 39 may be separately connected to the body belt 11 on the back side.

  FIG. 12 is a perspective view of a twelfth embodiment of the present invention, and the same reference numerals are given to the same parts as in FIG. In this embodiment, the side opposite to the affected side of the pad is cut to reduce the weight, and the elbow joint can have a degree of freedom of extension and bending within a certain range. Therefore, the lower side 51 of the pad 1 is joined to the body belt 11 by sewing, and the other parts of the pad 1, that is, the side sides 52 and 53 and the upper side 54 are the body. A pair of fasteners 55 is provided between the opposite portions of the belt 11, and both can be separated at these portions. With such a configuration, the elbow joint can be bent with reference to a limb position that does not give the elbow joint a degree of freedom, and a fixed brace that allows the elbow joint to move in the extending direction can be obtained. A part of this configuration is changed so that the upper side 54 of the pad 1 is joined to the body belt 11 by sewing, and the other parts of the pad 1, that is, the sides 52 and 53 and the lower side 51 are opposed to the body belt 11. If it is separable, the extension of the elbow joint is restricted, and a fixed device that allows movement in the bending direction is obtained. Furthermore, when there is a risk of excessive elbow joint extension or bending, or when it is desired to adjust the extension or bending angle of the elbow joint, a stopper member such as a string or belt is provided on the portion corresponding to the upper side of the pad 1 of the torso belt 11. Surface fasteners 58 and 59 are provided inside the front end so that one end of each of 56 and 57 can be attached and the other end can be attached to the upper surface of the pad 1, and the attachment position of the stopper members 56 and 57 on the pad is adjusted. The angle between 1 and the belt 11 can be set to a predetermined value.

  The connecting portion between the pad 1 and the waist belt 11 may use fasteners on all sides. In that case, when the extension or bending angle of the elbow joint can be changed as described above, What is necessary is just to make it close either the fastener between the upper side or lower side of a trunk belt. Moreover, you may use a hook_and_loop | surface fastener instead of the above-mentioned fastener.

  In this embodiment, unlike the embodiments described above, the body belt 11 is separated into a front body belt 116 and a rear body belt 117 that face the pads, and at both ends of the front body belt 116, cocans 118 and 119 are provided. Hooks 1110 and 1111 are attached to both ends of the rear waist belt 117, respectively, and both ends of the rear waist belt 117 are inserted into the cocans 118 and 119 and fixed by the folded surface fasteners 1110 and 1111. Can be worn. According to this configuration, the length of the trunk belt can be adjusted in two places, so that the applicable range of the trunk circumference can be widened, and when the front trunk belt and the rear trunk belt are made of different materials as required The manufacturing process can be facilitated. Further, the front arm fixing portion has a front end portion in which both sides of the forearm bag 22 are connected by a short belt 214 so that the hand portion and the forearm can be easily inserted and removed from the above-described embodiments. In this embodiment, the forearm belt 23 is formed wide and only one is different from the above-described embodiments.

  According to the twelfth embodiment, in addition to the elbow joint flexion of 90 degrees, when this angle does not need to be maintained, the angle is given a degree of freedom, and the patient has a more cramped limb position than is necessary for disease treatment. Wearing can be improved without forcing.

FIG. 13a is a perspective view of a thirteenth embodiment of the present invention, in which a part of the embodiment of FIG. 12 is changed, and the same parts as those of the embodiment of FIG. In this embodiment, the pad 1 is joined by hinges 61 and 62 only between the side sides 7 and 8 thereof and the opposite portions of the front waist belt 116, and the hinges 61 and 62 are rotated by pins 63 and 64, respectively. So that the angle of the pad 1 with respect to the front waist belt 116 can be adjusted. FIGS. 13b and 13c are enlarged perspective views of the hinges. As can be seen from the figure, ring-shaped stoppers 65 and 66 are provided on the opposite sides of the pins 63 and 64 of the hinges 61 and 62, respectively. When the stoppers 65 and 66 are rotated as indicated by arrows in the closed state, the hinge can be held in the closed position as shown in FIG. 13c. It is also possible to hold the hinge in an intermediate position by a stopper having another structure.

The pad, torso belt, forearm fixing part, shoulder belt, and elbow belt presented in each of the above-described embodiments can be combined with each other according to symptoms to constitute the shoulder joint fixing device of the present invention. In addition, when using a hook-and-loop fastener, for example, hook-type fasteners may be provided on one side of the connecting portion, and loop fasteners may be provided on the other, or a hook-and-loop fastener may be attached to only one side and the other. The surface may be formed of a material that can engage at least the surface with a hook-and-loop fastener.

  In Patent Document 4 described in the background art, a shoulder joint is held at a predetermined abduction angle by using a forearm suspension belt and sandwiching an armpit pad under the arm in a shoulder joint fixing device, and a fractured humerus Although it is disclosed that pressure is applied to soft tissues such as surrounding muscles and fats to keep the fracture site in a reduced position, this device cannot take angles other than slight abduction and internal rotation of the shoulder joint. In addition, since a force is applied in the vertical direction to the upper shoulder, the therapeutic effect intended by the present invention cannot be obtained. On the other hand, in the present invention, since the upper limb is held in the external rotation position, the shoulder joint portion of the shoulder belt can be angled on the chest surface side and the back surface side so that the shoulder joint has the front surface. Therefore, it is possible to enhance the therapeutic effect.

Further, in Patent Document 6 mentioned above, in the shoulder joint fixing device, a neck belt is attached to the forearm holding portion, and the neck belt is pulled rearward and outward along the torso belt, so that the forearm holding portion is rotated outwardly. Although this device does not have a function of holding the external rotation angle at a constant angle, and the neck belt is only attached to the forearm holding portion, it is as in the present invention. Even if the forearm moves inward, there is no function to suppress it. On the other hand, the elbow belt of the present invention prevents the internal rotation as described above, and can provide a good therapeutic effect.
