Description

Technical Field

[0001] This utility model relates to an orthosis, or more specifically, to an orthosis installed on a part of the human body (e.g., neck, torso, upper limb, lower limb). Background Technology

[0002] In Japanese Patent Application Publication No. 2000-342307, as in that document... Figure 1 As shown, a method is disclosed in which a locking piece is pre-installed on an annular component, and a fastening component is passed through the same annular component to engage the two.

[0003] Japanese Patent No. 5660357 discloses a directional hook-and-loop fastener, which, simply put, has the top of the entire lever protruding in a unidirectional direction. Japanese Patent Application Publication No. 6-133808... Figure 2 The same type of rod is also illustrated. Utility Model Content

[0004] Problems to be solved by the utility model

[0005] Various orthotics have been developed for patients undergoing treatment or rehabilitation of hemiplegia, fractures, paralysis, internal injuries, and external injuries, or for individuals requiring care. For example, medical compression garments are designed to fit the appropriate size for each part of the body affected by injuries such as spinal compression fractures or tibial fractures. However, they may not be easy to install, especially for patients or individuals requiring care.

[0006] The inventors of this application have discovered a new subject of providing orthotics with better user-friendliness. More specifically, Patent Document 2 discloses the use of hook and loop fasteners with a unidirectional engagement direction for diapers; however, the nonwoven fabric that adheres to the diaper body, i.e., nonwoven fabric, is used as the female-type hook and loop fastener.

[0007] means for solving problems

[0008] One aspect of the orthotic device disclosed herein includes one or more orthotic structural members and male and female members fixed at different positions on the one or more orthotic structural members. The male and female members engage to maintain an installation state relative to a part of the human body, and the pressure relative to the part of the human body can be adjusted by adjusting the engagement position of the male and female members. The male member includes a first base layer and a set of male engagement elements, which are arranged in a one-dimensional or two-dimensional pattern on the surface of the first base layer. The male-type engaging element includes a rod erected on the surface of the first base layer and a single protrusion projecting from the rod along the surface at a height away from the surface of the first base layer. The female-type element includes a second base layer and a set of female-type engaging elements formed as a regular or random set of rings on the surface of the second base layer. With the orthosis fitted to a part of the body, each protrusion of each of the male-type engaging elements in the set of male-type engaging elements projects from each rod along a single side of the circumference relative to the part of the body for preventing loosening of the orthosis. Both clockwise and counterclockwise directions can be defined for a circumferential direction, and the aforementioned single side of the circumferential direction corresponds to either clockwise or counterclockwise.

[0009] In some embodiments, the set of female engaging elements is formed as a regular set of rings, each ring of the set of rings being open in the circumferential direction or along the circumferential direction when the orthosis is mounted on a part of the human body.

[0010] In some embodiments, the set of female engaging elements is formed as a regular set of loops, and the set of male engaging elements and the set of female engaging elements are oriented in a manner that allows the orthotics to be tightened.

[0011] In some embodiments, the set of female engaging elements is formed as a regular set of rings, and after the male and female elements are engaged, one of the male and female elements can slide relative to the other in a manner that increases the compressive force of the orthodontic device.

[0012] In some embodiments, the engagement area between the male and female parts varies according to the sliding.

[0013] In some embodiments, both the male and female components are configured in a manner that does not restrict the sliding.

[0014] In some embodiments, the orthosis also includes adjustment fittings for generating the sliding.

[0015] In some embodiments, the adjustment fitting includes: a strap configured to at least partially encircle a portion of the human body, wherein, with the orthosis mounted on the portion of the human body, the orthotic structure is clamped between the portion of the human body and the strap; and a loop fitting through which one end of the strap passes, thereby enabling adjustment of the length of the strap encircling the portion of the human body.

[0016] In some embodiments, the set of male engagement elements and the set of female engagement elements are oriented in a manner that maximizes the shear strength of the laminate of the male and female elements when the orthosis is mounted on a part of the human body.

[0017] In some embodiments, the height of each ring of the set of rings from the surface of the second base layer is equal to the height of each male engaging element of the set of male engaging elements from the surface of the first base layer.

[0018] In some embodiments, the set of female engaging elements is formed as a random set of rings, which are random in at least the opening size, opening direction, and opening shape.

[0019] In some embodiments, the engagement load between the male and female parts is 0.3 N / cm. 2 the following.

[0020] In some embodiments, the elastic modulus of the thermoplastic resin constituting the male part is 250 MPa to 450 MPa.

[0021] In some implementations, the set of rings in the rule includes locking rings, and the random set of rings includes mohair rings.

[0022] In some implementations, when the orthosis is installed on part of the body, the protrusion direction of the protrusion and the opening direction of the ring are aligned or substantially aligned in the circumferential direction.

[0023] In some embodiments, with the orthosis mounted on a part of the human body, each of the protrusions of each of the set of male-type engaging elements protrudes from each of the rods in the same orientation.

[0039] Hereinafter, with reference to the accompanying drawings, non-limiting embodiments and features of this utility model will be described. It should be noted that the terms circumferential, inner, and outer are understood based on the human body part on which the orthotic 1 is installed. The inner side is aligned with the direction from the outer periphery of the human body part toward the human body part. The outer side is aligned with the direction from the outer periphery of the human body part toward the outer periphery of the human body part.

[0040] Figure 1An example of a non-limiting orthotic device 1 is shown. Orthotic device 1 is a type of medical device installed on a part of the human body (in the example shown, the waist), typically surrounding and compressing that part of the body. Orthotic device 1 has one orthotic structural member 2 and male-shaped members 3 fixed at different positions to the one orthotic structural member 2 (see reference). Figure 2 and Figure 3 ) and female type 4 (refer to Figure 4 By engaging the male component 3 and the female component 4, the orthosis 1 can be maintained in its installation position relative to a part of the human body. Furthermore, by adjusting the engaging position of the male component 3 and the female component 4, the pressure exerted by the orthosis 1 on the part of the human body can be adjusted. Figure 1 In this design, orthotic structural component 2 uses a single strip-shaped member with a length sufficient to encircle a portion of the human body; however, there are no limitations on the number or shape of orthotic structural components 2. Of course, variations in size and / or structure are permissible. Figure 1 The orthosis 1 shown is also used on other parts of the body (e.g., upper limbs, lower limbs). At the same time, the orthosis 1 can be changed from a soft type to a hard type. The soft type includes highly cushioned structural components, while the hard type includes rigid structural components such as metal plates or resin plates.

[0041] First, regarding male component 3 (refer to...) Figure 2 and Figure 3 ) is fixed (e.g., sewn) to the inner surface of the first part (simply put, the first end) 2a of the orthopedic structure 2, the female part 4 (refer to Figure 4 The form in which the orthotic structure 2 is fixed (e.g., sewn) to the outer surface of the second part (simply put, the second end) 2b is described. By fixing the second part 2b of the orthotic structure 2 to a predetermined position around the waist, and then rotating the first part 2a of the orthotic structure 2 around the waist and overlapping it onto the outer surface of the second part 2b, the female part 4 and the male part 3 are engaged face-to-face, thereby installing the orthotic 1 on the waist. The pressure of the orthotic 1 can be adjusted by changing the engagement position of the male part 3 and the female part 4. For a form in which the fixing positions of the male part 3 and the female part 4 are reversed, it will be described later with reference to FIG8.

[0042] Generally, the male component 3 and the female component 4 are the male and female components (simply put, hooks and loops) of a hook and loop fastener that can be continuously and repeatedly engaged and disengaged. However, there is no reason to limit the engagement element to a planar (two-dimensional) configuration. The male component 3 can be manufactured by general injection molding using an upper and lower mold assembly, or by using a mold wheel and an extruder with a molding cavity on the outer peripheral surface. The female component 4 can be manufactured from multiple yarns using an automatic loom. There is no limitation on the number of male and female components 3 and 4 included in the orthosis 1. It should be noted that the elastic modulus of the thermoplastic resin constituting the male component 3 is preferably 150 MPa to 600 MPa, and more preferably 250 MPa to 450 MPa. When the elastic modulus is less than 150 MPa, the engagement force may decrease; when the elastic modulus exceeds 600 MPa, the male component 3 becomes hard, and the feel and operability may deteriorate.

[0043] Optionally, the orthosis 1 may also have an adjustment fitting 5. The adjustment fitting 5 is used for tightening the orthosis 1, particularly for sliding, as described later. As an example, the adjustment fitting 5 includes: a strap 6 that at least partially wraps around a part of the human body; and a loop fitting 7 through which one end of the strap 6 passes, thereby enabling adjustment of the length of the strap wrapping around the part of the human body. The strap 6 is fixed (e.g., sewn) to the outer surface of the orthosis structure 2 within any range between the first part 2a and the second part 2b, with the loop fitting 7 attached to one end of the strap 6, and the free end of the other end of the strap 6 can be inserted into the loop fitting 7. By pulling the free end of the other end of the strap 6 through the loop fitting 7, the length of the strap wrapping around the human body can be adjusted, resulting in tightening of the orthosis 1. It should be noted that since the orthosis structure 2 is sandwiched between a part of the human body and the strap 6, it is preferable to include a highly cushioning material (e.g., a cushioning material incorporated into a highly breathable mesh fabric). Adjustment accessory 5 can take various forms; for example, it can be a hook and loop fastener sewn onto the first part 2a. As long as the male hook and loop fastener is fixed to the inner surface of the free end of the other end of the strap 6, it can fit into part of the strap 6 that surrounds a part of the human body.

[0044] like Figure 2 and Figure 3 As shown, the male-shaped component 3 has a first base layer 31 and male-shaped engaging elements 32 arranged in a one-dimensional or two-dimensional manner on the surface of the first base layer 31 to form a set of male-shaped engaging elements G32. The first base layer 31 is fixed to the inner surface of the first part 2a of the orthodontic structure 2 by stitching, bonding, welding, etc., and each male-shaped engaging element 32 of the set of male-shaped engaging elements G32 protrudes inward from the first part 2a of the orthodontic structure 2. Generally, the first base layer 31 is formed to a certain thickness, but it can also be partially thinned, and it can also have slits to improve deformability.

[0045] A set of male-type engaging elements G32 is arranged in M ​​columns × N rows, where M and N represent natural numbers greater than 2. Typically, a set of male-type engaging elements G32 is arranged at a density of 20–100 per cm. 2 The density is arranged in a two-dimensional pattern. At less than 20 particles / cm³... 2 In such cases, it may be difficult to sufficiently obtain the peel strength and shear strength of the orthosis 1 achieved through engagement with the female part 4. (The last part, "more than 100 / cm", appears to be an error and is left untranslated.) 2 In such cases, the tightening process described later may not be able to proceed smoothly.

[0046] It should be noted that the peel strength is expressed as the force required to pull one of the male component 3 and the female component 4 apart from the other in the normal direction when they are in the engaged state (e.g., holding one end of the male component 3 and peeling it off from the female component 4). The shear strength is expressed as the force required to misalign one of the male component 3 and the female component 4 in the tangential direction when they are in the engaged state. The engagement initiation load (initial engagement load) is expressed as the force required to move one of the male component 3 and the female component 4 in the disengaged state toward the other in the normal direction and initiate engagement.

[0047] Figure 2 The illustration shows a total of 16 male-type snap-fit ​​elements 32 arranged in 4 columns × 4 rows, but this number is only an example. Figure 2 The column direction D is shown. column and direction D row This can be used as a reference as needed. The male-type engaging element 32 is in the column direction D. column Arranged in the top, adjacent male engaging elements 32 form a receiving space for the ring 43 of the female element 4, described later. The male engaging elements 32 are in the row direction D. row The elements are arranged in an upward manner to form a space that allows the ring 43 to connect to the male engagement element 32.

[0048] The male engaging elements 32 of the set of male engaging elements G32 are not mushroom-shaped with no defined engaging direction in the circumferential direction, but rather hook-shaped with a unidirectional engaging direction in the circumferential direction. Each male engaging element 32 includes: a rod 32a, which stands upright on the surface of the first base layer 31; and a single protrusion 32b, which protrudes from the rod 32a along the surface at a height away from the surface of the first base layer 31. The height direction of the male engaging element 32 is consistent with the thickness direction D1 of the first base layer 31. The protrusion 32b protrudes from the rod 32a, thereby forming a space SP1 between the protrusion 32b and the surface of the first base layer 31. Generally, the protrusion 32b extends from the top of the rod 32a, which is furthest from the surface of the first base layer 31, thereby increasing the flatness of the top of the rod 32a and reducing irritation to the skin. The protruding direction D2 of the protrusion 32b is parallel to the surface of the first base layer 31 and can be aligned with the column direction D.column Consistent.

[0049] The male-type engaging element 32 has a first side surface 91 on the same side as the protrusion 32b and a second side surface 92 on the opposite side of the first side surface 91. The first side surface 91 rises approximately vertically from the surface of the first base layer 31, and the second side surface 92 rises obliquely from the surface of the first base layer 31 toward the first side surface 91. The obliqueness of the second side surface 92 facilitates smooth sliding, as described later. The male-type engaging element 32 also has a top surface 93 in the rising direction of the rod 32a, a front end surface 94 in the protruding direction of the protrusion 32b, and an arcuate surface 95 extending between the front end surface 94 and the first side surface 91. Arcuate surfaces are formed between the top surface 93 and the second side surface 92, and between the top surface 93 and the front end surface 94, thereby reducing irritation to the skin. The arcuate surface 95 can prevent the ring 43, described later, from easily disengaging from the male-type engaging element 32. It should be noted that the male engaging element 32 has two sides, namely side 96 and side 97, on the transverse direction D3 orthogonal to the thickness direction D1 of the first base layer 31 and the protrusion direction D2 of the protrusion 32b (see reference). Figure 2 The male engaging element 32 may also have auxiliary protrusions 39a and 39b on both sides of the rod 32a in the transverse direction D3, but these can be omitted.

[0050] like Figure 4 As shown, the female component 4 includes a second base layer 41 and a set of female engaging elements G42 formed on the surface of the second base layer 41 as a regular set of rings G43. The second base layer 41 is fixed to the outer surface of the second part 2b of the orthodontic structure 2 by stitching, bonding, welding, etc. Each female engaging element 42 of the set of female engaging elements G42 protrudes outward from the second part 2b of the orthodontic structure 2. Generally, the second base layer 41 is formed to a certain thickness, but it can also be partially thinned, and it can also have slits to improve deformability. The set of female engaging elements G42 is the same as the set of male engaging elements G32, at a ratio of 20 to 100 per cm. 2 The density in this range is arranged in a two-dimensional pattern, and is generally the same as the density of a set of male engaging elements G32. Needless to say, the female element 4 can have different planar dimensions (column width and / or row width) than the male element 3, and the total number of elements in each part does not need to be consistent.

[0051] When a set of rings G43 are regularly formed on the surface of the second base layer 41, unlike nonwoven fabric (fiber assembly) which lacks directionality in engagement, the engagement direction is limited to unidirectional, similar to the male engagement element 32. A representative example of this configuration is the locking ring. Each ring 43 is preferably a closed loop, in the thickness direction D1' of the second base layer 41 (refer to...). Figure 4The ring 43 has a height and a width in the width direction D3', one of two directions orthogonal to the thickness direction D1'. Furthermore, the ring 43 opens in the opening direction D2', orthogonal to both the thickness direction D1' and the width direction D3'. The opening direction D2' can be aligned with or along the circumference of the part of the body when the orthosis 1 is installed on it. The height of each ring 43 can be equal to the height of the male engaging element 32. The opening of the ring 43 is formed to accommodate an area sufficient to accommodate the protrusion 32b. It should be noted that "equal" means that the difference between the two values ​​of the comparison objects is less than 5% of the larger value, and also includes complete agreement.

[0052] Generally, during the weaving or knitting process of the second base layer 41, a set of loops G43 are formed, and the yarns (or filaments) of the second base layer 41 are continuous with the yarns (or filaments) of the loops 43, but this is not a limitation. The loops 43 may have intersections near the second base layer 41 where the yarns (e.g., bundles of filaments) intersect each other, and have a minimum width at these intersections. The loops 43 may have a maximum width at the position between the intersection and the top.

[0053] In this embodiment, the female component 4 includes a regular set of rings G43, and, with the orthosis 1 installed on a part of the human body, each (generally all) male engagement element 32 protrudes 32b from each rod 32a along one side circumferentially with respect to the part of the human body to prevent loosening of the orthosis 1. Thus, a more user-friendly orthosis 1 can be provided; in other words, it can maintain or improve the installation stability of the orthosis 1 while promoting smooth tightening of the orthosis 1. It should be noted that the state of the orthosis 1 being installed on a part of the human body as described in this specification refers to the state resulting from the engagement of the male component 3 and the female component 4. Each protrusion 32b may protrude from each rod 32a in the same or similar orientation, but is not necessarily limited to this.

[0054] The circumference can be understood by referring to the imaginary circle IC designed for a part of the human body with orthotics 1 installed (the waist in the example figure) (see reference). Figure 1 The male member 3 is fixed to the first part 2a and moves in direction B by operating the adjusting accessory 5, thereby smoothly tightening the orthosis 1. Direction B is unilateral in the circumferential direction that increases the pressure on the orthosis 1 relative to the moving part (first part 2a and the male member 3 fixed to the first part 2a). Direction B' is unilateral in the circumferential direction that decreases the pressure on the orthosis 1 relative to the moving part (first part 2a and the male member 3 fixed to the first part 2a).

[0055] In the configuration where the male component 3 is fixed to the inner surface of the first part 2a of the orthotic structure 2, and the female component 4 is fixed to the outer surface of the second part 2b of the orthotic structure 2, the protruding direction D2 of the protrusion 32b (and "one side along the circumferential direction of the part of the human body used to prevent loosening of the orthotic 1") is consistent with direction B'. In the configuration where the positions of the male component 3 and the female component 4 are reversed, the protruding direction D2 of the protrusion 32b (and "one side along the circumferential direction of the part of the human body used to prevent loosening of the orthotic 1") is consistent with direction B.

[0056] A set of male engaging elements G32 and a set of female engaging elements G42 are oriented in a manner that allows the orthosis 1 to tighten. More specifically, after the male element 3 and the female element 4 are engaged, one of the male element 3 and the female element 4 can slide relative to the other in a manner that increases the compressive force of the orthosis 1 (simply put, the male element 3 can slide in direction B). Further reference is made to these features. Figures 5 to 7 Let's explain in more detail. It should be noted that, regarding the use of adjustment accessory 5, the stacked body of male part 3 and female part 4 is pressed inward by belt 6, thus causing sliding to occur when the two are in close contact.

[0057] By fixing the second part 2b of the orthotic structure 2 to a predetermined position around the waist, and then rotating the first part 2a of the orthotic structure 2 around the waist and overlapping it on the outer surface of the second part 2b, the female part 4 and the male part 3 are engaged face-to-face, thereby temporarily installing the orthotic 1 on the waist (see reference). Figure 5 and Figure 6 Next, adjust accessory 5 by passing the free end of the other end of the belt 6 through its loop accessory 7, thereby shortening the belt length around the waist and tightening it. At this time, the first part 2a and the male part 3 are displaced in direction B, thus successfully tightening the orthosis 1 (see reference). Figure 7 For example, comparison Figure 6 and Figure 7 To illustrate, the male engaging element 32z disengages from the ring 43z and moves to a position where it can engage with other rings in the same row as the ring 43z (e.g., 43z-2). The tightening of the orthosis 1 by the adjusting accessory 5 can be smoothly implemented without being hindered by the initial engagement of the male part 3 and the female part 4 for temporary installation of the orthosis 1.

[0058] With the orthosis 1 installed on a part of the human body, for each or all of the male engagement elements 32 of the set of male engagement elements G32, the protruding direction D2 of the protrusion 32b from the rod 32a is preferably aligned with or substantially aligned with one side of the circumferential direction, specifically, with direction B'. "Substantially aligned" means that the angle between the protruding direction D2 and direction B' is less than 15°, less than 10°, or less than 5°. For the female member 4, generally, with the orthosis 1 installed on a part of the human body, each ring 43 of the set of rings G43 is open in the circumferential direction. It is best if the protruding direction D2 of the protrusion 32b and the opening direction D2' of the ring 43 are aligned or substantially aligned in the circumferential direction with the orthosis 1 installed on a part of the human body. In this case, the shear strength of the laminate of the male member 3 and the female member 4 is maximized, and the installation strength of the orthosis 1 is also maximized. At the same time, the sliding resistance related to the aforementioned sliding is minimized.

[0059] Reference Figure 6 and Figure 7 It is understandable that the engagement area of ​​male component 3 and female component 4 can vary according to the aforementioned sliding. Alternatively, the engagement area could be fixed based on the dimensions of both components, independent of sliding. In the former case, smaller components can be used, thus reducing costs, and it is also sufficient for temporary installation of the orthosis 1. Both male component 3 and female component 4 can be configured to not restrict the aforementioned sliding. This simplifies the structure of each component, thereby reducing the burden of carefully confirming the orientation of the components during fixation.

[0060] When the fixed positions of male part 3 and female part 4 are reversed, female part 4 moves circumferentially relative to male part 3; however, the same result can be obtained as long as the above-described features are present. For this reason, please refer to Figure 8. In Figure 8, with... Figure 5 In contrast, the fixed positions of the female component 4 and the male component 3 have been reversed. However, correspondingly, the positions of the first part 2a and the second part 2b have also been reversed, with the former positioned on the inside and the latter on the outside. In this case, the first part 2a and the male component 3 are stationary, while the second part 2b and the female component 4 slide relative to them in the circumferential direction (compare with Figures 8(a) and 8(b)), but the same result can be obtained as long as the above-described features are present.

[0061] Reference Figures 9 to 13 Alternative implementation methods will be described. For example... Figure 9As shown, the female member 4, similar in form to the one described above, includes a second base layer 41 and a set of female engaging elements G42 formed as a set of rings G43 on the surface of the second base layer 41. However, the set of female engaging elements G42 is formed as a random set of rings G43. Therefore, although the aforementioned sliding cannot be achieved, the initial engagement load between the male member 3 and the female member 4 can be effectively reduced, thereby providing a more user-friendly orthosis 1. For example, it is easier to perform operations such as installing the orthosis 1 on the left foot with the right hand.

[0062] A set of loops G43 is random in at least the opening size, opening direction, and opening shape. Loop 43 can be a closed loop, but it can also be an open loop. In some cases, the yarn length (filament length) forming a loop may vary, thereby increasing the randomness of the loop. Similar to the above-described configuration, loop 43 can be formed during the weaving or knitting process of the second base layer 41. The filaments of the second base layer 41 and the filaments of the loop 43 can be continuous, but are not limited to this; other yarns that should form the loop can also be inserted in a manner interwoven with the base yarn (e.g., warp or weft) of the second base layer 41. Typically, the female part 4 is a so-called mohair-type hook and loop fastener. A random set of loops G43 includes mohair loops. Mohair loop is a commonly used name in this art, but its material is not limited to mohair.

[0063] Advantageously, the initial engagement load between the male part 3 and the female part 4 is preferably 0.3 N / cm. 2 The following is more suitable at 0.01 N / cm 2 ~0.3N / cm 2 Within the specified range. The engagement start load measurement is as follows. First, the male component 3 is positioned above the female component 4, and with a set of male engagement elements G32 facing a set of female engagement elements G42, a downward load is applied to the male component 3. The area of ​​the set of male engagement elements (G32) of the male component 3 is 4.9 cm². 2 At this point, the load that initiates the engagement (hooking) of a set of male engaging elements (G32) and a set of female engaging elements (G42) is called the "engagement initiation load." For more information, refer to... Figure 10 Compared to the comparative example, in the embodiment, the engagement start load was significantly reduced to 0.1 N / cm. 2 Left and right. The reason is... Figure 2 The male component 3 shown is... Figure 9The result of combining the female component 4 shown is illustrated. It should be noted that in the comparative example, a combination of male components with a double-headed hook shape and female components with a locking ring shape was used. "Double-headed hook shape" refers to a shape in which a pair of protrusions extend from the top of the rod in opposite directions (direction B and direction B') in the circumferential direction. In this embodiment, compared to the comparative example, the integral value of the peel strength (N / cm) is slightly reduced (see reference). Figure 11 However, the maximum shear strength (N / cm) 2 Add (refer to) Figure 12 The reduction in initial engagement load is sufficient to compensate for the reduction in peel strength. Furthermore, the increase in shear strength also allows for the miniaturization of the male part 3, which in turn facilitates a reduction in the cost of the orthotine 1.

[0064] Figure 2 The male component 3 shown is... Figure 9 The combination of female component 4 shown is not limited to Figure 1 The orthotics 1 shown can also be used Figure 13 The orthotics shown is 1. Figure 13 The orthotic device 1 shown consists of six orthotic structural components, namely, curved plates 71 and 72 made of metal or resin, connecting straps 73 and 74, and opening and closing straps 75 and 76. The opening and closing strap 75 passes through a ring fitting 7 fixed to the curved plate 72 from its free end 75a and folds back, overlapping the inner portion of the opening and closing strap 75 itself (e.g., near its fixed end 75b). For example, the male component 3 is fixed to the inner surface of the portion of the opening and closing strap 75 that passes through the ring fitting 7 and folds back (e.g., near the free end 75a), and the female component 4 is fixed to the outer surface of the inner portion of the opening and closing strap 75 (e.g., near the fixed end 75b) (and vice versa). When the male component 3 engages with the female component 4, as described above, due to the low initial engagement load, engagement is easy, thus facilitating the installation of the orthotic device 1. As described above, with the male member 3 fixed to the inner surface of the portion near the free end 75a of the opening and closing band 75, and the female member 4 fixed to its opposite side, each protrusion 32b of each male engagement element 32 of a set of male engagement elements G32 is used along the set of male engagement elements G32 to prevent loosening of the orthodontic 1 on one side (i.e., from the front view). Figure 13 (On the right side of the paper) protrudes from each rod 32a.
