Description

  The present invention relates to a brace.

  As a brace that holds the waist, a hard brace formed from a hard material such as celluloid and a soft brace formed from a soft material such as cloth are known (see Patent Document 1 and Non-Patent Document 1). ). A rigid brace is difficult to deform, restricts the movement of the lumbar spine, and reduces the burden on the lumbar region. On the other hand, since a flexible orthosis has a certain amount of flexibility, the movable range of the waist is ensured.

JP 59-22544 A Published by the Planning Department of the Techno-Aid Association, Auxiliary Equipment Expenses Guidebook (2018 revised version), p. 131-189

  However, since the hard device is formed of a hard material such as a celluloid plate, if the air hole is formed in order to ensure air permeability, the device itself may be damaged. In addition, when wearing a low-breathing device, the lumbar region is likely to be stuffy during wearing, and sweat may be scratched as it drip.

  Then, this invention makes it a subject to provide the brace which has favorable air permeability, having suitable intensity | strength.

As means for solving the above-mentioned problems, the present invention includes a belt-like appliance main body wound around an affected part , a first reinforcing member that is detachably attached to the appliance main body and has a plate shape that reinforces the appliance main body, 2 reinforcing members, a first surface fastener set for detachably attaching the first reinforcement member to the appliance body, and a second surface fastener set for detachably attaching the second reinforcement member to the appliance body , a brace for holding the affected area, the orthosis body is strip-shaped body made of resin having flexibility, meshed der formed of a plurality of vent holes is, the first surface fastener assembly set The number of the second surface fastener sets is different from the number of the second surface fastener sets .
Further, as a means for solving the above-mentioned problems, the present invention is a belt-like device body wound around an affected part, and is attached to one end portion of the device body, and is overlapped inside the other end portion of the device body when worn. A tongue-shaped overlapped portion, a first reinforcing member that is detachably attached to the inner surface of the overlapped portion and reinforces the appliance main body, and the facing the overlapped portion A second reinforcing member that is detachably attached to the inner surface of the orthosis main body and that is in the form of a plate that reinforces the orthosis main body, and a first surface fastener group that detachably attaches the first reinforcing member to the overlapped portion; And a second hook-and-loop fastener set for detachably attaching the second reinforcing member to the orthosis body, the orthosis holding the affected area, wherein the orthosis body is a flexible resin band. so Ri is a mesh-like formed of a plurality of vent holes, a brace, wherein different from the number of pairs of the second surface fastener sets the number of pairs of the first surface fastener assembly.

  According to such a configuration, since the orthosis main body has a mesh shape in which a plurality of ventilation holes are formed, the affected area is less likely to be stuffy during the attachment of the orthosis. In addition, since the orthosis main body is a flexible strip made of a resin, it has higher strength than a soft orthosis formed of a soft material such as cloth and can hold the affected area well.

Furthermore, since the orthosis main body has flexibility, that is, flexibility, it deforms while flexing following the movement of the affected part. This makes it difficult to form a gap (gap) between the orthosis main body and the affected part. That is, the contact rate between the orthosis main body and the affected area is a good value, and the supportability of the affected area by the orthosis is improved.
Furthermore, by attaching the reinforcing member to the appliance main body, the appliance main body is reinforced, and the strength becomes equivalent to that of a rigid appliance formed of a hard material such as a celluloid plate. In addition, since the reinforcing member can be attached to and detached from the appliance main body, the strength of the appliance can be easily adjusted. Furthermore, since the reinforcing member has a plate shape, the strength of the orthosis main body is suitably increased, and the affected part can be favorably held.

  Moreover, the said orthosis main body is good also as a structure which restores | restores to a basic shape in a no-load state.

  Here, the no-load state means a state where no external force is acting on the appliance body. For example, when the affected part is a trunk, an unloaded state means a state in which bending stress (external force) is not applied from the trunk to the orthosis body due to the forward bending or backward warping of the trunk.

  The basic shape means a shape corresponding to the affected part in the basic state (natural state, neutral state). For example, when the affected part is a trunk, the basic state means an upright state, not a forward bent state or a back warped state.

  Therefore, according to such a configuration, the orthosis main body has a basic shape in an unloaded state, so that the patient can attach the orthosis to the affected area without any gap. Further, since the orthosis main body is restored to the basic shape in an unloaded state, that is, when the affected part returns to the basic state and the external force is lost, the orthosis main body returns to the basic shape, so that the patient can comfortably wear the orthosis.

  The first reinforcing member and the second reinforcing member may have a plurality of air holes for ensuring air permeability.

  Moreover, it is good also as a structure provided with the non-slip sheet | seat for fixing the inner surface of the said apparatus main body, and the surface having adhesiveness for preventing the shift | offset | difference during mounting | wearing.

  Moreover, it is good also as a structure where the fiber is mixed in the said apparatus main body.

  According to such a configuration, since the fiber is mixed in the appliance main body, the strength of the appliance main body is increased, and the affected part can be favorably held. Moreover, the intensity | strength of an orthosis main body can be easily changed by changing the kind, length, and content of a fiber.

  ADVANTAGE OF THE INVENTION According to this invention, the brace which has favorable air permeability, having favorable intensity | strength can be provided.

It is a perspective view of the brace concerning this embodiment. It is a figure of the right front part of the orthosis which concerns on this embodiment, (a) has shown the state which removed the front reinforcement plate, (b) has shown the state which mounted | wore the front reinforcement plate. It is a figure of the left front part of the orthosis which concerns on this embodiment. It is a figure of the rear part of the brace concerning this embodiment, (a) shows the state where the back reinforcement plate was detached, and (b) shows the state where the back reinforcement plate was installed. It is a rear view of the orthosis which concerns on this embodiment.

  An embodiment of the present invention will be described with reference to FIGS. In addition, although the case where the brace | wear 1 is a person's waist is illustrated here, the use of this invention is not limited to this. Further, in the following description, “front, rear, left, right, upper, lower” shown in FIG. 1 is used as a reference.

≪Configuration of the brace≫
The orthosis 1 is a medical instrument that holds an affected part P (trunk) of a patient having a spinal (medullary) disease. The trunk is a part that points to the neck and torso, and does not include limbs. The appliance 1 includes an appliance body 10, a front reinforcing plate 21 and a rear reinforcing plate 24, two attachment belts 31, and a fastening belt 41. However, a configuration without the fastening belt 41 may be used.

<Body body>
The orthosis main body 10 is a cylindrical body having a belt-like belt-like body wound around the affected part P and having a substantially C shape in a plan view and having an open front side. That is, the appliance main body 10 includes a right front portion 10A on the right front side, a left front portion 10B on the left front side, and a rear portion (rear side) 10C.

  The appliance main body 10 is made of resin and has flexibility. The thickness of the appliance main body 10 is approximately 0.5 mm to 5.0 mm. As the resin, for example, a thermoplastic resin, specifically, polypropylene, low density / high density polyethylene, and ethylene vinyl acetate can be used.

  Thus, since the orthosis main body 10 has flexibility and a softness | flexibility (body movement follow-up property), for example, when a patient bends the affected part P by bending forward or curving, the orthosis main body 10 follows this and the orthosis main body 10 follows. It comes to bend. Thereby, it is difficult to form a gap (gap) between the brace body 10 and the affected part P, and the contact rate (human body contact rate) of the brace body 10 to the affected part P is maintained well.

  However, the appliance main body 10 can be changed by changing the combination of the type, length, and content of fibers, the size and number of the reinforcing members 17, the size of the front reinforcing plate 21, the size of the rear reinforcing plate 24, and the like. The strength of the can also be dramatically increased. According to such a high-strength appliance main body 10, for example, immediately after an operation, it is possible to realize a highly restrictive body movement of the affected part P in response to a doctor's request.

  In this manner, the orthosis main body 10 has flexibility (flexibility), but improves the contact rate without deteriorating the fixability of the affected part P, so that the supportability (fixability) of the affected part P is improved. ). On the other hand, when the appliance main body 10 does not follow the motion of the affected part P and a gap is formed between the appliance main body 10 and the affected part P, the appliance main body 10 is supported by the degree of formation of the gap. The nature will decline.

  Moreover, since the orthosis main body 10 is resin, it is lightweight with respect to metal orthoses. Specifically, the orthosis body 10 is about 1/2 to 2/3 of the conventional product.

  The yield strength of such an orthosis main body 10 is designed to be 9000 (N / m) or more in the case of a trunk orthosis, and is designed to be 3000 (N / m) or more in the case of an upper limb orthosis or a lower limb orthosis. The Yield strength is the maximum stress that can be generated in a material without causing plastic deformation.

  In addition, the appliance main body 10 is mixed with fibers. For example, the fiber is kneaded into a resin kneaded material before molding of a resin mesh sheet serving as a base material of the appliance body 10. As the fiber, for example, a short fiber or a long fiber can be used, and specifically, cellulose nanofiber, carbon fiber, carbon nanofiber, or the like can be used. One fiber may be used, or a plurality of fibers may be mixed and used.

  Thus, since the fiber is mixed, the intensity | strength of the orthosis main body 10 becomes high and the affected part P can be hold | maintained favorably. Moreover, the intensity | strength of the orthosis main body 10 can be changed easily by changing the kind, length, and content of a fiber. However, a configuration in which fibers are not mixed in the appliance main body 10 may be used.

  Furthermore, in order to improve antibacterial (bactericidal) and deodorant properties, a configuration may be adopted in which an antibacterial agent is mixed (kneaded) or attached to the appliance body 10. As the antibacterial agent, for example, silver, copper metal solid, metal ion, metal complex can be used.

  A plurality of vent holes 11 having substantially the same shape and substantially the same shape are formed over the entire body 10, and the body 10 has a mesh shape. Thereby, the orthosis main body 10 has favorable air permeability, and the affected part P is hard to be stuffy while the orthosis 1 is mounted, and comfort is ensured. The size of the vent hole 11 is approximately 3 mm to 20 mm. The shape of the vent hole 11 is not particularly limited, and may be any of a circle, a triangle, a quadrangle, a pentagon, a hexagon, and the like. In addition, although the several ventilation hole 11 is formed in this way, since the orthosis main body 10 has flexibility, the orthosis main body 10 is not damaged during mounting | wearing.

  The ratio of the entire vent hole 11 to the brace body 10 (area of the entire vent hole 11 / area of the brace body 10, the biological contact rate, the vent hole ratio) is, for example, 20 to 90%, preferably 30 to 90%, and more preferably. Is 35 to 65%. When the ratio of the vent holes 11 is increased, the air permeability is improved, but the strength of the appliance main body 10 is reduced. Therefore, it is preferable to design in consideration of the material of the appliance main body 10, the state of the affected part P, and the like.

  It is also possible to change the proportion of the entire vent 11 corresponding to the type of the affected part, that is, corresponding to the type of the appliance 1. For example, when the orthosis 1 is a trunk orthosis or a lower limb orthosis, the proportion of the entire vent 11 may be designed to be 50 to 55%, and when the orthosis is an upper limb orthosis, it may be designed to be 30 to 40%.

  Furthermore, in order to improve the breathability and mounting property (fitness) in the brace 1, a configuration in which a thin sheet-like backing material (lining, lining material) is affixed to the inner peripheral surface of the brace body 10 may be used. The backing material has, for example, a three-layer structure mainly composed of polyester, and is formed in a thin cushion sheet shape having a thickness of about 1.0 mm to 4.0 mm.

  Specifically, the backing material is a high-density base sheet that is affixed to the appliance main body 10, a surface sheet that is disposed on the affected part P side and has a plurality of air holes of about 1.0 mm to 3.0 mm, A sponge-like intermediate layer disposed between the base sheet and the top sheet and having elasticity and breathability. The backing material may be configured to be affixed to the entire inner peripheral surface of the appliance main body 10 or may be configured to be partially (for example, only on the front abdomen side) affixed to a highly adhesive portion.

  Furthermore, in order to prevent displacement of the brace 1 during mounting, a configuration in which a non-slip sheet is partially attached to the inner peripheral surface of the brace body 10 may be adopted. The surface of the non-slip sheet preferably has adhesiveness, for example, an adhesive layer mainly composed of polyvinyl chloride is formed. Moreover, it is preferable that the non-slip sheet is affixed to the inner peripheral surface of the appliance main body 10 corresponding to a relatively hard portion (for example, pelvis) in the vicinity of the affected part P.

  Moreover, the orthosis main body 10 is comprised so that it may restore | restore to a basic shape in a no-load state. That is, the orthosis main body 10 stores a basic shape corresponding to the external shape in the basic state of the affected part P (trunk). The no-load state is a state in which no bending stress (external force) is applied to the orthosis main body 10 due to the forward bending motion or the backward warping motion of the trunk. The basic state is a natural state or a neutral state, and here, it is an upright state, not a forward bent state or a back warped state.

  That is, even if the appliance main body 10 is bent due to a load (external force), the appliance main body 10 has a restoring force that spontaneously returns to the basic shape corresponding to the affected part P when it enters an unloaded state. Thereby, the brace 1 can hold the affected part P satisfactorily while attaching the brace body 10 to the affected part P without any gap.

  For example, the memory of the basic shape in the appliance main body 10 can be obtained by, for example, heating a polypropylene mesh sheet (resin molded sheet) as a base material to a temperature at which plastic deformation is possible (for example, 150 to 200 ° C.) or more. Then, it can be performed by plastically deforming it along a gypsum waist mold modeled on the affected part P, and then allowing it to cool.

  An edge tape 12 (bias tape) is attached to the outer peripheral edge of the appliance body 10. Thereby, the affected part P is not damaged during wearing of the brace 1 while preventing damage to the outer peripheral edge.

  As shown in FIG. 2, a tongue-shaped overlapped portion 13 is attached to the right front portion 10A. The overlapped portion 13 is a portion that is overlapped on the inside of the left front portion 10B of the appliance main body 10 at the time of wearing, and is formed of, for example, artificial leather. Two hook-and-loop fasteners 14 and 14 are fixed to the inner surface of the overlapped portion 13. The hook-and-loop fastener 14 is a portion that is combined with the hook-and-loop fastener 22 of the front reinforcing plate 21 described later. For example, the hook-and-loop fastener 14 is a loop type (female type), and the hook-and-loop fastener 22 is a hook type (male type).

  As shown in FIG. 3, two elongated frame-shaped rings 15 and 15 are fixed to the left front portion 10 </ b> B by ring holding members 16 and 16, respectively, so as to be rotatable. The ring 15 is a portion where a mounting belt 31 to be described later is inserted and turned back.

  On the outer peripheral surfaces of the right front portion 10A (see FIG. 2), the left front portion 10B (see FIG. 3), and the rear portion 10C (see FIG. 4), an elongated plate-like reinforcing member 17 extending in the vertical direction is fixed. Specifically, a cloth cover member covering the reinforcing member 17 is fixed to the appliance main body 10. The reinforcing member 17 is made of duralumin or resin, for example, and is reduced in weight. In addition, the structure by which the reinforcement member 17 was fixed to inner peripheral surfaces, such as 10 A of right front parts, may be sufficient.

  As described above, since the reinforcing members 17 are fixed to the right front portion 10A, the left front portion 10B, and the rear portion 10C, the bending strength of the appliance main body 10 is dramatically increased. Thereby, the orthosis main body 10 can hold | maintain the affected part P favorably. Further, since the reinforcing member 17 has an elongated plate shape, the air permeability of the appliance main body 10 does not deteriorate.

  The number of reinforcing members 17 is not limited to three and can be changed as appropriate. That is, increasing the number of reinforcing members 17, increasing the width, or increasing the thickness increases the strength of the orthosis main body 10, further restricts the body movement of the affected area P, and increases the restraint force of the orthosis 1. You can also. The same applies to the front reinforcing plate 21 and the rear reinforcing plate 24 described later.

  A hook-and-loop fastener 18 is fixed to the inner peripheral surface (see FIG. 4A) of the rear portion 10C. The hook-and-loop fastener 18 is a portion to be combined with the hook-and-loop fastener 25 of the rear reinforcing plate 24 described later.

<Front reinforcement plate, rear reinforcement plate>
As shown in FIG. 2, the front reinforcing plate 21 is a plate-like resin member that is detachably attached to the overlapped portion 13 (the appliance body 10) and reinforces the appliance body 10. Two hook-and-loop fasteners 22 and 22 are fixed to the front surface of the front reinforcing plate 21. The two hook-and-loop fasteners 22 are matched with the two hook-and-loop fasteners 14 and 14 described above. The front reinforcing plate 21 is formed with a plurality of vent holes 23 for ensuring air permeability.

  As shown in FIG. 4, the rear reinforcing plate 24 is a plate-like resin member that is detachably attached to the rear portion 10 </ b> C of the appliance main body 10 and reinforces the appliance main body 10. One hook-and-loop fastener 25 is fixed to the rear surface of the rear reinforcing plate 24. One hook-and-loop fastener 25 is matched with the above-described one hook-and-loop fastener 18. The rear reinforcing plate 24 is formed with a plurality of ventilation holes 26 for ensuring air permeability.

  As described above, the front reinforcing plate 21 is attached with two sets of hook-and-loop fasteners (hook fasteners 14 and 22), and the rear reinforcing plate 24 is attached with one set of hook-and-loop fastener sets (hook fasteners 18 and 25). . That is, since the number of hook-and-loop fastener sets is different between the front and rear, erroneous mounting of the front reinforcing plate 21 and the rear reinforcing plate 24 is prevented.

<Belt for wearing>
As shown in FIGS. 1 and 2, the two attachment belts 31 are members that are stretched between the right front portion 10 </ b> A and the left front portion 10 </ b> B of the appliance body 10 when the appliance 1 is attached. However, the number of the belts 31 for attachment is freely changeable. The base of each mounting belt 31 is fixed to the right front portion 10 </ b> A of the appliance body 10. A hook-and-loop fastener 32 is fixed to the ½ base side of the mounting belt 31, and a hook-and-loop fastener 33 is fixed to the ½ tip side. For example, the hook-and-loop fastener 32 is a loop type, and the hook-and-loop fastener 33 is a hook type.

  When the brace 1 is mounted, the front end of each mounting belt 31 is inserted through the ring 15 and then turned back so that the hook-and-loop fastener 32 and the hook-and-loop fastener 33 are aligned.

<Tightening belt>
As shown in FIGS. 1 and 5, the tightening belt 41 is a belt that is used to increase the tightening force of the affected part P by the brace 1 while the brace 1 is being worn. The fastening belt 41 includes substantially V-shaped rubber portions 42 and 42 extending in the circumferential direction from the rear reinforcing member 17, a hook-and-loop fastener 43 fixed to the tip of the right rubber portion 42, and a right rubber portion 42. And a hook-and-loop fastener 44 fixed to the tip. Here, the hook-and-loop fastener 43 is constituted by a hook type, and the hook-and-loop fastener 44 is constituted by a loop type.

  Each rubber part 42 is formed in a substantially V shape by fixing one end of two elastic rubber bands to the reinforcing member 17 and stitching the other ends together. Since the elastic rubber portion 42 is substantially V-shaped in this way, the tightening force by the tightening belt 41 acts evenly in the vertical direction and is tightened as a whole in a wide range in the vertical direction. However, for example, the rubber part 42 may be constituted by a single wide rubber band.

  Then, the fastening belt 41 is fastened by overlapping the hook-and-loop fastener 43 and the hook-and-loop fastener 44 while extending the rubber portions 42 and 42. As a result, the tightening belt 41 is configured to tighten the affected part P via the appliance main body 10.

≪Effect of brace≫
The effect of the brace 1 will be described.
Since the brace body 10 has a mesh shape in which a plurality of ventilation holes 11 are formed and has air permeability, the affected part P is less likely to be stuffy and does not scratch sweat as dripping. Moreover, since the orthosis main body 10 is a resin-made strip | belt-shaped body which has flexibility, while being lightweight, intensity | strength becomes higher than a soft orthosis and the affected part P can be hold | maintained favorably.

  In addition, since the appliance main body 10 is configured to be restored to the basic shape in an unloaded state, the appliance 1 can be attached to the affected part P without any gap. That is, the patient can comfortably wear the brace 1.

  Furthermore, when the front reinforcing plate 21 and the rear reinforcing plate 24 are attached to the appliance main body 10, the strength of the appliance 1 becomes equivalent to that of a conventional rigid appliance. On the other hand, when the front reinforcing plate 21 and the rear reinforcing plate 24 are detached from the appliance main body 10, the strength of the appliance 1 becomes equivalent to that of a conventional flexible appliance. That is, by attaching / detaching the front reinforcing plate 21 and the rear reinforcing plate 24, the strength of the appliance 1 can be changed according to the state of the affected part P. In other words, the patient does not need to own a hard or soft appliance corresponding to the treatment recovery status of the affected part P or the like.

  Furthermore, since the fiber is mixed in the appliance main body 10, the strength of the appliance main body 10 is improved satisfactorily. Thereby, the orthosis main body 10 can hold | maintain the affected part P favorably.

  Further, by appropriately combining the fiber, the reinforcing member 17, the front reinforcing plate 21, and the rear reinforcing plate 24, not only the flexibility (body movement followability) of the appliance 1 but also the body movement in the affected part P can be limited. .

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to this, For example, you may change as follows.

  In the above-described embodiment, the configuration in which the orthosis 1 holds (fixes) the trunk is exemplified. However, for example, fingers, elbows, shoulders, neck (cervical vertebra), chest (thoracic vertebra), sacral spine, crotch, knees, The structure which hold | maintains a leg | foot etc. may be sufficient. That is, the present invention may be applied to any of a lower limb orthosis, a shoe-type orthosis, a trunk orthosis, and an upper limb orthosis. Further, the orthosis 1 may be configured to hold and support, for example, a part that is separated or a part that is different from the muscle.

  In the above-described embodiment, the configuration in which the brace 1 is for humans (for humans) is exemplified, but other configurations such as for dogs, cats, birds, and other animals may be used.

  In the above-described embodiment, the device 1 has been illustrated with the configuration including the front reinforcing plate 21 and the rear reinforcing plate 24. However, for example, the number of reinforcing plates and the mounting position can be freely changed.

  In the above-described embodiment, the configuration in which the reinforcing member 17 is fixed to the appliance main body 10 is illustrated. However, for example, the reinforcing member 17 may be detachable from the appliance main body 10. In this case, for example, it can be configured by attaching a pocket capable of accommodating the reinforcing member 17 to the appliance body 10.

  In the above-described embodiment, the configuration in which the hook-and-loop fastener 32 and the hook-and-loop fastener 33 are fixed together in the mounting belt 31 is exemplified. However, for example, a mounting belt extending from the right front portion 10A is attached to the left front portion 10B. It may be configured to be fastened to a fixed buckle. The same applies to the fastening belt 41.

  In the above-described embodiment, the configuration in which the vent hole 11 is formed in the entire orthosis body 10 is illustrated, but the size and distribution (density) of the vent hole 11 can be freely changed.

  In the above-described embodiment, the orthosis main body 10 exemplifies a configuration corresponding to the basic shape of the affected part P (trunk), that is, a configuration that is a tailor-made product (custom product) individually corresponding to each patient. For example, the configuration may be a ready-made product (standard product) such as S size, M size, and L size. In this case, the basic shape of the appliance main body 10 in the no-load state (basic state) is designed based on, for example, a standard body shape.

  In the above-described embodiment, the configuration in which the orthosis main body 10 is a cylindrical body that is substantially C-shaped in plan view and is open on the front side is exemplified. However, for example, the orthosis main body 10 may be divided in the front-rear direction. That is, for example, when the orthosis main body 10 is seen in a plan view, the front half on the front side having a 2/3 arc shape and the rear half on the rear side having a 2/3 arc shape are partially overlapped on both sides of the waist. May be configured. In this case, the assembled state of the front half and the rear half is maintained by, for example, a hook-and-loop fastener. Such a configuration is sometimes referred to as a sandwich type because the front half and the rear half sandwich the affected part P.

  In the above-described embodiment, the orthosis main body 10 has a single layer configuration, that is, a configuration in which one mesh sheet after plastic deformation is illustrated, but in addition, for example, a multilayer configuration in which a plurality of mesh sheets are stacked as a whole, A configuration in which mesh sheets are partially overlapped may be used. That is, for example, the mesh sheet may have a two-layer structure only in a portion to be reinforced such as a portion to which the reinforcing member 17 is fixed. Thus, the strength of the appliance body 10 can be partially increased by partially forming the mesh sheet in a multilayer structure.
