Embodiments for Carrying Out the Invention

[0009] Hereinafter, preferred embodiments for carrying out the present invention will be described with reference to the drawings. The embodiments described below show typical embodiments of the present invention, and the scope of the present invention is not limited only to these embodiments.

[0010] Unless otherwise specified, in this specification, "up" means the upward direction in the figure, "down" means the downward direction in the figure, "left" means the leftward direction in the figure, and "right" means the rightward direction in the figure.

[0011] 1. First Embodiment (Appliance)

[0012] 1-1. Overview of the Appliance

[0013] The overview of the appliance according to the first embodiment of the present invention will be described. The appliance according to this embodiment is used for wearing a medical fixing material that fixes a part of the body. The medical fixing material is a medical device formed to fix a part of the body, but it cannot be worn on the body alone. Therefore, the medical fixing material is worn on the body while being held by the appliance according to this embodiment, and thereby, a state in which a part of the body can be fixed is maintained. Hereinafter, as an example, an appliance used for wearing a plate-shaped medical fixing material on the arm will be described, but the appliance of the present invention is not limited thereto.

[0014] FIG. 1 is a plan view of the appliance 1. The plan view shows the appliance 1 in a plan view as seen from the body side with the first main body 10 on the upper side and the second main body 20 on the lower side. In this specification, "body side" means the side facing the body in a state where the appliance (first main body) is worn on the body.

[0015] The appliance 1 includes a first main body 10 and a second main body 20. The first main body 10 and the second main body 20 are separably connected by a connecting portion 30. The first main body 10 and the second main body 20 shown in FIG. 1 are in a connected state. When the connection is released, the first main body 10 and the second main body 20 are separated, and the second main body 20 can be removed from the first main body 10.

[0016] Figures 2A to 2D show the orthosis 1 fitted to the arm. Specifically, Figures 2A to 2D show the orthosis 1 fitted to the arm viewed from the palmar side, dorsal side, radial side, and ulnar side, respectively. As shown in these figures, the orthosis 1 can be fitted to cover the part of the hand other than the fingers, the forearm, and the elbow. In other words, the fixation area of ​​the orthosis 1 is the part of the hand other than the fingers, the forearm, and the elbow.

[0017] On the other hand, the orthosis 1 can be attached to the arm even when the second main body 20 is removed. That is, when the first main body 10 and the second main body 20 are separated, the first main body 10 is configured to allow the attachment of a medical fixation material. Figures 3A to 3C show the first main body 10 attached to the arm. Specifically, Figures 3A to 3C are views of the first main body 10 attached to the arm from the palmar side, the dorsal side of the hand, and the radial side, respectively. As shown in these figures, the first main body 10 can be attached so as to cover the part of the hand other than the fingers and the forearm. That is, the fixation area of ​​the first main body 10 is the part of the hand other than the fingers and the forearm.

[0018] As described above, the orthosis 1 according to this embodiment can change the fixation range depending on whether the second body 20 is present or absent when worn. Specifically, the orthosis 1 can widen the fixation range by having the second body 20 when worn, and narrow the fixation range by not having the second body 20.

[0019] 1-2. Composition of the orthotic device

[0020] 1-2-1. Overall Structure

[0021] The orthotic device 1 according to this embodiment will now be described in detail. First, the overall configuration of the orthotic device 1 will be described with reference to Figures 1 and 2A to 2D. As shown in Figure 1, the orthotic device 1 comprises a first body 10, a second body 20, and a connecting part 30.

[0022] As shown in Figure 1, in a plan view of the orthosis 1 from the body side with the first body 10 on top and the second body 20 on the bottom, the connecting portion 30 may be provided, for example, on at least a part of the lower end of the first body 10 and at least a part of the upper end of the second body. This allows the second body 20 to be connected to the lower side of the first body 10.

[0023] In Figure 1, the connecting portion 30 is connected, and the first body 10 and the second body 20 are connected. When the connecting portion 30 is disconnected, the first body 10 and the second body 20 become separated. The connecting portion 30 can be reconnected, for example, after being disconnected. That is, the first body 10 and the second body 20 may be reconnected after being separated. In this way, because the first body 10 and the second body 20 can be repeatedly connected and disconnected, the range of fixation by the orthosis 1 can be changed multiple times. Therefore, the orthosis 1 can be repeatedly used with multiple fixation methods that have different fixation ranges.

[0024] The first body 10 may be equipped with an attachment member 17 for attaching the first body 10 to a part of the body. The attachment member 17 may be provided, for example, on at least a part of the left end of the first body 10, as shown in Figure 1. Two attachment members 17 are shown in Figure 1, but the number of attachment members is not limited to this and may be at least one.

[0025] The second body 20 may be provided with mounting members 23 for attaching the second body 20 to a part of the body. The mounting members 23 may be provided, for example, on at least a part of the lower end of the second body 20 as shown in Figure 1. Although one mounting member 23 is shown in Figure 1, the number of mounting members 23 is not limited to this and may be at least one.

[0026] Figures 2A to 2D show the orthosis 1 worn on the arm. As shown in Figures 2A, 2C, and 2D, the first body 10 can be worn on the arm by attaching the mounting member 17 of the first body 10 to the outer surface of the first body 10. Also, as shown in Figures 2B to 2D, the second body 20 can be worn on the arm by attaching the mounting member 23 of the second body 20 to the outer surface of the first body 10. In this specification, "outside" refers to the side that is on the outside when the orthosis (first body) is worn on the body (the side opposite to the side facing the body).

[0027] The mounting member 17 and the attachment member 23 are preferably detachably attached to the outer surface of the first body 10. For example, the outer surface of the first body 10, the mounting member 17, and the attachment member 23 may each have a hook-and-loop fastener portion. For example, the outer surface of the first body 10 may have a loop surface, and the mounting member 17 and the attachment member 23 may each have a hook surface. The outer surface of the first body 10 may be formed of, for example, a fabric member whose surface is napped in a loop shape.

[0028] As shown in Figure 1, the orthosis 1 may further include a hand-mounted member 40 that is worn on the hand and has finger insertion holes 41 into which fingers are inserted. The hand-mounted member 40 may be connected, for example, to at least a portion of the upper end of the first main body 10. In this case, the first main body 10 may have finger insertion holes 14 similar to the finger insertion holes 41 of the hand-mounted member 40. Also, as shown in Figure 1, the orthosis 1 may include a through member 42 that is inserted through the finger insertion holes 41 of the hand-mounted member 40 and the finger insertion holes 14 of the first main body 10, connecting at least a portion of the lower end of the hand-mounted member 40 and at least a portion of the upper end of the first main body 10. For example, the hand-mounted member 40 and the first main body 10 may be connected by passing a strip-shaped through member 42 through both the finger insertion holes 41 of the hand-mounted member 40 and the finger insertion holes 14 of the first main body 10 and securing it.

[0029] As shown in Figures 2A to 2D, the hand-mounted member 40 may be attached to the hand, for example, by overlapping the outer surface of the first main body 10. That is, the hand-mounted member 40 may be attached to the hand indirectly, for example, by sandwiching the first main body 10. For example, the thumb may be inserted into the finger insertion hole 41 of the hand-mounted member 40 and the finger insertion hole 14 of the first main body 10. The hand-mounted member 40 may be configured to be detachable, for example, by a hook-and-loop fastener.

[0030] As shown in Figures 2A to 2D, the orthosis 1 may include a belt portion 90. The belt portion 90 may be attachable to any position on the orthosis 1. This allows the belt portion 90 to be positioned appropriately regardless of individual differences in body size (e.g., individual differences in forearm length). The belt portion 90 may be wrapped around, for example, the first body 10 and the second body 20 attached to the body. This allows the first body 10 and the second body 20 to be more firmly fixed to the body. The belt portion 90 may be detachable, for example, by a hook-and-loop fastener.

[0031] Next, the configuration of the connecting portion 30 will be described with reference to Figure 4. Figure 4 is a diagram of the connecting portion 30. Specifically, Figure 4 shows the state after the upper end of the second main body 20 has been peeled back after the connecting portion 30 has been detached.

[0032] The connecting portion 30 may include a first body-side connecting portion 31 provided on the first body 10 and a second body-side connecting portion 32 provided on the second body 20. The first body-side connecting portion 31 may include a first engaging portion 311 and a second engaging portion 312. The second body-side connecting portion 32 may include a third engaging portion 321 and a fourth engaging portion 322.

[0033] When the first body 10 and the second body 20 are connected (see Figure 1), the first engaging portion 311 and the third engaging portion 321 are engaged, and the second engaging portion 312 and the fourth engaging portion 322 are engaged. As shown in Figure 4, when the first body 10 and the second body 20 are separated, all of these engagements are released. Thus, the first engaging portion 311 and the third engaging portion 321 can be engaged and disengaged, and the second engaging portion 312 and the fourth engaging portion 322 can be engaged and disengaged. Therefore, the connection and disengagement of the connecting portion 30 can be achieved by the connection and disengagement of the first body-side connecting portion 31 and the second body-side connecting portion 32. More specifically, these connection and disengagement can be achieved by the connection and disengagement of the first engaging portion 311 and the third engaging portion 321, and the connection and disengagement of the second engaging portion 312 and the fourth engaging portion 322.

[0034] To reconnect the separated first body 10 and second body 20, the first engaging portion 311 and the third engaging portion 321 may be re-engageable after being disengaged, for example. In addition, the second engaging portion 312 and the fourth engaging portion 322 may be re-engageable after being disengaged, for example.

[0035] The connecting portion 30 (specifically the first to fourth engaging portions), including the first main body-side connecting portion 31 and the second main body-side connecting portion 32, may be formed by, for example, at least one selected from known members. The known members may be formed by, for example, at least one selected from a fitting member having a removable convex part and a recessed part (e.g., a snap button), a hook, a button and buttonhole, a magnet, a hook-and-loop fastener, and a zipper. Among these members, the preferred member is a fitting member having a removable convex part and a recessed part (e.g., a snap button). For example, if the connecting portion (first to fourth engaging portions) is formed by a hook-and-loop fastener, variations in the connecting (engaging) position may reduce the connecting force. Specifically, for example, if the area where the loop surface and hook surface constituting the hook-and-loop fastener overlap is small, the connecting force may decrease. On the other hand, in the case of the above-mentioned fitting member, variations in the connecting (engaging) position are less likely to occur, so the reduction in connecting force as described above can be suppressed. Furthermore, the fitting member is one of the members that can be easily engaged and disengaged. Because the connecting portion 30 is formed of the fitting member, the first body 10 and the second body 20 can be easily connected and separated.

[0036] 1-2-2. First main body and second main body

[0037] Next, the configurations of the first body 10 and the second body 20 will be described with reference to Figure 1. The first body 10 and the second body 20 each include a fixation material holder for holding at least one medical fixation material. That is, the first body 10 includes a fixation material holder for holding at least one medical fixation material. The second body 20 includes a fixation material holder for holding at least one medical fixation material. Figure 1 shows the first fixation material holder 15, the second fixation material holder 22, and the third fixation material holder 16 as examples of fixation material holders. The first fixation material holder 15 and the third fixation material holder 16 are provided on the first body 10. The second fixation material holder 22 is provided on the second body 20.

[0038] As shown in Figure 1, the first fixation material holder 15 and the second fixation material holder 22 may be detachably connected by a connecting portion 30. The connected first fixation material holder 15 and the second fixation material holder 22 may form a single fixation material holder, thereby enabling the joint holding of one or more medical fixation materials. In this way, by having the first fixation material holder 15 and the second fixation material holder 22 as an integrated unit, the orthotic device 1 can hold medical fixation materials with a large surface area (for example, long medical fixation materials).

[0039] In the above-described configuration, the first main body side connecting portion 31 (see Figure 4) included in the connecting portion 30 may be provided on the first fixing member holding portion 15, and more specifically, it may be provided on at least a part of the lower end of the first fixing member holding portion 15. Also, the second main body side connecting portion 32 (see Figure 4) included in the connecting portion 30 may be provided on the second fixing member holding portion 22, and more specifically, it may be provided on at least a part of the upper end of the second fixing member holding portion 22.

[0040] 1-2-3. First fixing member holding part and third fixing member holding part

[0041] Next, referring to Figure 1, the configurations of the first fixation material holder 15 and the third fixation material holder 16 provided on the first main body 10 will be described. In a plan view of the orthosis 1 (first main body 10) as seen from the body side, the first fixation material holder 15 and the third fixation material holder 16 may be arranged side by side. For example, the first fixation material holder 15 may be on the right side and the third fixation material holder 16 may be on the left side.

[0042] The first fixing member holding portion 15 and the third fixing member holding portion 16 may be arranged, for example, on either side of the strip-shaped member 13. That is, the first main body 10 may include the strip-shaped member 13. In the first main body 10, the strip-shaped member 13 may be positioned in the middle, the first fixing member holding portion 15 may be positioned to the right of the strip-shaped member 13, and the third fixing member holding portion 16 may be positioned to the left of the strip-shaped member 13. The strip-shaped member 13 shown in Figure 1 extends in the vertical direction, the vertical direction in Figure 1 is the length direction of the strip-shaped member 13, and the left-right direction in Figure 1 is the width direction of the strip-shaped member 13.

[0043] The first fixation material holder 15 includes a main storage area 151 for accommodating a medical fixation material. The main storage area 151 may be an area that accommodates the entire medical fixation material, or an area that accommodates the majority of the medical fixation material. "The majority of the medical fixation material" may be, for example, 70% or more, 80% or more, 85% or more, 90% or more, 95% or more, or 98% or more of the surface area of ​​the medical fixation material, but is not limited to these.

[0044] The main storage area 151 has a main storage opening 152 that allows for the insertion and removal of medical fixation materials. The medical fixation materials are inserted through the main storage opening 152 and held in place by being housed in the main storage area 151.

[0045] The main housing area 151 may include a first base member 11 located on the outside and a main cover member 153 located on the body side when the orthosis 1 (first main body 10) is worn. That is, the main housing area 151 may be formed by the first base member 11 and the main cover member 153, and may be the area enclosed by them. In Figure 1, the main cover member 153 is opened from the main housing opening 152 (the main cover member 153 is opened to the right), and the main housing area 151 and the first base member 11 are depicted in a visible manner. As shown in Figure 1, at least a portion of the left end of the first base member 11 may be joined to the strip-shaped member 13.

[0046] The main housing opening 152 may be formed by the partial joining of the first base member 11 and the main cover member 153. For example, the first base member 11 and the main cover member 153 may be joined at the right end as shown in Figure 1. The unjoined portions of the first base member 11 and the main cover member 153, i.e., the lower end, left end, and upper end, may constitute the main housing opening 152.

[0047] Preferably, at least a portion of the main housing opening 152 opens inward when viewed from the body side in a plan view of the orthosis 1 (first body 10). Specifically, "opens inward" means that, in a state in which a medical fixation material can be held (with the main cover member 153 closed), at least a portion of the main housing opening 152 forms an opening facing the direction of the middle part of the orthosis 1 (first body 10). In the first body 10 shown in Figure 1, the strip-shaped member 13 is positioned in the middle part of the first body 10, and when the main cover member 153 is closed, the main housing opening 152 becomes an opening facing the direction of the middle part (the direction of the strip-shaped member 13).

[0048] As described above, because the main receiving opening 152 opens inward, the medical fixation material is less likely to fall out of the first fixation material holding part 15 when being worn. For example, consider the case where the orthosis 1, which holds the medical fixation material with the first fixation material holding part 15, is worn on the forearm and elbow as shown in Figures 2A to 2D. When wearing the orthosis 1, the elbow is usually bent at about 90° with the radius side facing the opposite direction of gravity, and the band-shaped member 13 and its surroundings are applied to the radius side (see Figure 2C). At this time, since the main receiving opening 152, which is located on the body side, is facing the opposite direction of gravity, the possibility of the medical fixation material falling out of the main receiving opening 152 downwards (i.e., in the direction of gravity) is reduced.

[0049] The main storage opening 152 is not limited to being an opening that faces inward, but may also be a non-opening type. If it does not face inward, the medical fixation material may be more likely to fall out during insertion or other procedures. In this case, it is preferable to provide an engaging means (for example, a hook-and-loop fastener, snap button, or hook) at the storage opening to close the medical fixation material in order to prevent it from falling out. However, if such an engaging means is provided, it becomes more troublesome to engage and disengage the engaging means when inserting or removing the medical fixation material. On the other hand, if the main storage opening 152 is configured in a way that makes it difficult for the medical fixation material to fall out, such an engaging means is not essential, and inserting and removing the medical fixation material can be done more easily if there is no engaging means.

[0050] The first fixation material holding section 15 preferably includes an end-receiving area 154 for accommodating the end of the medical fixation material. Specifically, the end-receiving area 154 may be an area that accommodates only the end of the medical fixation material. By accommodating the end of the medical fixation material in the end-receiving area 154, displacement of the medical fixation material accommodated in the main accommodating area 151 can be suppressed.

[0051] The end of the medical fixation material housed in the end housing area 154 may, for example, include a portion of the peripheral edge of the medical fixation material. If the medical fixation material has a shape that includes, for example, a corner or a rounded corner, the end of the medical fixation material housed in the end housing area 154 is preferably a corner or a rounded corner. For example, if the medical fixation material is formed using a curable resin, generally, the medical fixation material is housed in the orthotic device before curing, and then the medical fixation material is cured. In this case, the corners and rounded corners of the medical fixation material are parts that are prone to bending or wrinkling when housed in the orthotic device. If bending or wrinkling occurs in the medical fixation material during housed, it may not be possible to position the medical fixation material in the correct location in the orthotic device. However, as described above, having an end housing area 154 suitable for housing corners or rounded corners makes it easier to visually check whether bending or wrinkling has occurred in the corners or rounded corners during housed. As a result, folds and wrinkles are less likely to occur at corners or rounded corners, making it easier to position medical fixation materials in the correct location.

[0052] In this embodiment, the main housing opening 152 is not limited to the form described above. For example, at least a portion of the main housing opening 152 may open toward the periphery when viewed in a plan view of the orthosis 1 (first body 10) from the body side. Specifically, "open toward the periphery" means that, in a state in which a medical fixation material can be held (with the main cover member 153 closed), at least a portion of the main housing opening 152 forms an opening that faces toward the peripheral part of the orthosis 1 (first body 10) (opposite direction to the middle part).

[0053] The end-receiving area 154 has an end-receiving opening 155 that allows the end of the medical fixation material to be inserted into and removed from the end. The end of the medical fixation material is inserted through the end-receiving opening 155 and held in place by being housed in the end-receiving area 154.

[0054] The end-receiving area 154 may include the first base member 11 located on the outside and the end-cover member 156 located on the body side when the orthosis 1 (first main body 10) is worn. That is, the end-receiving area 154 may be formed by the first base member 11 and the end-cover member 156, and may be the area enclosed by them.

[0055] The end housing opening 155 may be formed by partially joining the first base member 11 and the end cover member 156. For example, the first base member 11 and the end cover member 156 may be joined at the upper end and left end as shown in Figure 1. The portion where the first base member 11 and the end cover member 156 are not joined, that is, the portion facing the main housing area 151 (main housing opening 152 and main cover member 153), may be the end housing opening 155.

[0056] In a plan view of the orthotic device 1 (first main body 10) from the body side, the end receiving opening 155 preferably opens toward the main receiving area 151. Specifically, at least a portion of the main receiving opening 152 and at least a portion of the end receiving opening 155 preferably face each other. By configuring the device to accommodate the medical fixation material by opening the main receiving opening 152 and the end receiving opening 155 which face each other in this way, the recessed portions of the main receiving area 151 and the end receiving area 154 become easier to see. Therefore, when accommodating the medical fixation material, it becomes easier to visually check whether folds and wrinkles have occurred around the periphery of the medical fixation material. As a result, folds and wrinkles are less likely to occur around the periphery of the medical fixation material, and the medical fixation material is easier to position in the appropriate location.

[0057] When the main cover member 152 of the main housing area 151 is closed, at least a portion of the main cover member 152 and at least a portion of the end cover member 154 preferably overlap each other. This effectively suppresses displacement of the medical fixation material housed in the main housing area 151 and the end housing area 154. The shapes of the main cover member 152 and the end cover member 154 are not limited to this. For example, when the main cover member 152 and the end cover member 154 are closed, they do not necessarily have to overlap each other.

[0058] Next, the shape of the third fixing member holder 16 may be similar to that of the first fixing member holder 15, for example. The third fixing member holder 16 may be symmetrical or nearly symmetrical with respect to the first fixing member holder 15, for example, with respect to the intermediate part of the first main body 10 (e.g., the strip-shaped member 13) as the axis of symmetry. "Nearly symmetrical shape" means that the shape does not need to be perfectly symmetrical, and includes, for example, cases where members and regions having the same function are provided in nearly symmetrical positions, but some members and / or shapes are different.

[0059] The third fixing member holding section 16 shown in Figure 1 is substantially symmetrical to the first fixing member holding section 15 with respect to the strip-shaped member 13 as the axis of symmetry, but some members and shapes differ from those of the first fixing member holding section 15. The third fixing member holding section 16 includes a main housing area 161 and an end housing area 164. The main housing area 161 has a main housing opening 162. The end housing area 164 has an end housing opening (not shown). The main housing area 161 includes a second base member (not shown) and a main cover member 163 joined to the strip-shaped member 13. The end housing area 164 includes a second base member (not shown) and an end cover member 166. Details of these members and areas included in the third fixing member holding section 16 are as described in the description of the first fixing member holding section 15, and that description also applies to the third fixing member holding section 16.

[0060] The third fixing member holding part 16 differs from the first fixing member holding part 15 in the following respects, for example: The third fixing member holding part 16 does not have a connecting part 30 (first main body side connecting part 31) at its lower end. The main cover member 163 and the second base member are joined at the lower left end 169 of the third fixing member holding part 16. The lower right end of the third fixing member holding part 16 is not joined. This ensures that the main cover member 163 can be easily opened while preventing the medical fixing member from protruding from the lower end.

[0061] 1-2-4.Second fixing material holding part

[0062] Next, the configuration of the second fixing material holding section 22 will be described with reference to Figure 1. The second fixing material holding section 22 includes a storage area 221 for accommodating medical fixing materials. The storage area 221 has a storage opening 222 that allows medical fixing materials to be inserted and removed. The second fixing material holding section 22 can hold medical fixing materials by accommodating the medical fixing materials inserted through the storage opening 222 into the storage area 221.

[0063] The containment area 221 may include a base member 21 located on the outside and a cover member 223 located on the body side when the orthosis 1 is worn. That is, the containment area 221 may be formed by the base member 21 and the cover member 223, and may be the area enclosed by them. In Figure 1, the cover member 223 is opened from the containment opening 222 (the cover member 223 is opened to the right), and the containment area 221 and the base member 21 are depicted in a visible manner.

[0064] The receiving opening 222 may be formed by partially joining the base member 21 and the cover member 223. For example, the base member 21 and the cover member 223 may be joined at the right end, lower end and lower left end as shown in Figure 1. The unjoined portions of the base member 21 and the cover member 223, i.e., the left end and upper end excluding the lower left end, may form the receiving opening 222.

[0065] Preferably, the receiving opening 222 opens in the same direction as the main receiving opening 152 of the first fixing member holding part 15. This makes it easier to open the integrated receiving opening (the main receiving opening 152 of the first fixing member holding part 15 and the receiving opening 222 of the second fixing member holding part) when the first fixing member holding part 15 and the second fixing member holding part 22 are connected to form a single fixing member holding part.

[0066] 1-2-5. Orthotic device with the second main body removed.

[0067] Next, with reference to Figure 5, the orthosis 1 in the state with the second main body removed will be described. Figure 5 is a plan view showing the state with the second main body 20 shown in Figure 1 removed. In Figure 5, the main cover member 153 is slightly opened from the main housing opening 152 (the main cover member 153 is slightly opened to the right), and the main housing area 151 and a part of the first base member 11 are depicted to be visible.

[0068] The orthotic device 1 in the state shown in Figure 5 can be attached to the body as shown in Figures 3A to 3C. That is, the first main body 10 is configured to allow the attachment of medical fixation materials on its own.

[0069] The first body 10 includes a first body-side connecting portion 31. The first body-side connecting portion 31 includes a first engaging portion 311 and a second engaging portion 312. When the first body 10 and the second body are separated, the first engaging portion 311 and the second engaging portion 312 are engageable. Figure 5 shows the first engaging portion 311 and the second engaging portion 312 in an engaged state. This engagement makes it less likely for the medical fixation material to protrude from the lower end.

[0070] In order to enable engagement of the first engaging portion 311 and the second engaging portion 312, it is preferable that a part of the second body 20 is connected so as to overlap with the interior of the main housing area 151 of the first body 10, as shown in Figure 1. That is, as shown in Figure 1, when the first body 10 and the second body 20 are connected, it is preferable that a part of the second body 20 (for example, the upper end of the second body 20) is located inside the main housing area 151 of the first body 10 (for example, the lower end of the interior of the main housing area 151). In this case, preferably, the first engaging portion 311 is provided on the first base member 11, and the second engaging portion 312 is provided on the main cover member 153. Specifically, as can be understood from Figures 1 and 4, the first engaging portion 311 is preferably provided on the surface of the first base member 11 facing the main cover member 153. The second engaging portion 312 is preferably provided on the surface of the main cover member 153 facing the first base member 11. In this case, the second body-side connecting portion 20 (third engaging portion 321 and fourth engaging portion 322) is preferably provided on the surface of the second body 20 facing the first body 10. Specifically, as can be seen from Figures 1 and 4, the third engaging portion 321 is preferably provided on the surface of the base member 21 facing the first body 10 (first base member 11). The fourth engaging portion 322 is preferably provided on the surface of the cover member 223 facing the main cover member 153.

[0071] 1-3. Materials for orthotic devices

[0072] The components constituting the orthotic device of this embodiment are mainly formed using textile products. These textile products may be various fabrics such as knitted fabrics, woven fabrics, and nonwoven fabrics. Examples of knitted fabrics include double raschel fabric, plain knit fabric, rib knit fabric, pearl knit fabric, tuck knit fabric, circular knit fabric, weft knit fabric, tricot fabric, raschel fabric, pile knit fabric, and reinforcing knit fabric. Examples of fibers and yarns used in the above-mentioned fabrics include polyamide fibers, polyester fibers, acrylic fibers, cellulose fibers (e.g., cotton, rayon, polynosic, and lyocell), polyurethane fibers, polyolefin fibers (e.g., polyethylene and polypropylene), acetate fibers, polyvinylidene chloride fibers, polyvinyl chloride fibers, animal fibers (e.g., wool and other animal hairs), and yarns made from one or more of these fibers. Examples of yarn types include monofilament, multifilament, twisted yarn, covered yarn, and core yarn. These yarns may be subjected to various processing such as stretch processing and bulking processing. The textile products used in the orthosis of this embodiment are selected according to the attachment site of the orthosis and the purpose of use of the orthosis, and may consist of one type or a combination of two or more types. Each component constituting the orthosis does not need to be made from the same type of textile product, and may be made from different types of textile products.

[0073] Among the components included in the above-mentioned orthotic device, components having a predetermined function, such as connecting parts, attachment parts, mounting parts, and wrapping parts, may be formed using materials other than the above-mentioned textile products that have that function.

[0074] 1-4. Medical Fixation Materials

[0075] The medical fixation material held by the orthotic device according to this embodiment is a medical device formed to fix a part of the body, and may be, for example, a medical fixation material as described in the third embodiment later. Furthermore, the medical fixation material may be a medical fixation material known in the art. Examples of such known medical fixation materials include splints containing curable resin. The shape and size of the medical fixation material may be appropriately selected according to the part and shape of the body to be fixed, the fixation range, and the fixation method.

[0076] 1-5. Examples of medical fixation materials.

[0077] Next, an example of the accommodation of a medical fixation material in the orthotic device according to this embodiment will be described with reference to Figures 6 to 8. Figure 6 is a plan view enlarged from the area enclosed by the dashed line in Figure 1. In Figure 6, the main cover member 163 is opened from the main housing opening 162 (the main cover member 163 is opened to the left), and the main housing area 161 and the second base member 12 are depicted in a visible manner. Figure 7 is a schematic diagram showing the state in which the medical fixation material 900 is housed in the main housing area 161 shown in Figure 6. To hold the medical fixation material 900 in the main housing area 161, as shown in Figures 6 and 7, the main cover member 163 is opened and the medical fixation material 900 is placed in the main housing area 161. After that, when the main cover member 163 is closed, the medical fixation material 900 is held between the main cover member 163 and the second base member.

[0078] Figure 8 is a schematic diagram showing the state in which the rounded corner portion 910 of the medical fixing material 900 is housed in the end housing area 164 shown in Figure 6. The rounded corner portion 910 of the medical fixing material 900 is also shown in Figure 7. To hold the rounded corner portion 910 of the medical fixing material 900 in the end housing area 164, as shown in Figure 8, the end cover member 166 is opened from the end housing opening 165 and the rounded corner portion 910 of the medical fixing material 900 is inserted into the end housing area. After that, when the end cover member 166 is closed, the rounded corner portion 910 of the medical fixing material 900 is held in place by being sandwiched between the end cover member 166 and the second base member.

[0079] 1-6. Uses of orthotic devices

[0080] The orthotic device according to this embodiment is used to attach a medical fixation material to fix a part of the body. The orthotic device may be used, for example, to fix a part of the body in order to alleviate any impairment when some kind of impairment occurs in the function of that part of the body. The orthotic device may be used, for example, to fix a part of the body (affected area) in order to treat a fracture, dislocation, or damage to muscles, tendons, ligaments, or cartilage.

[0081] The orthosis according to this embodiment can be attached to various parts of the body. For example, the orthosis according to this embodiment may be an upper limb orthosis attached to the upper limb. The part to which the upper limb orthosis is attached may be at least one selected from the shoulder, upper arm, elbow, forearm, wrist, hand, and fingers. As an example, the orthosis according to this embodiment may be an upper limb orthosis that fixes the entire forearm with a first body and a second body, and fixes the wrist-side half of the forearm with only the first body. The first body may be further divisible so that the fixation range can be narrowed from the wrist-side half of the forearm to the vicinity of the wrist. As another example, the orthosis according to this embodiment may be an upper limb orthosis that fixes the part of the hand other than the fingers up to the upper arm including the elbow with a first body and a second body, and fixes the forearm (excluding the hand) up to the elbow with only the first body.

[0082] The orthosis according to this embodiment may be a trunk orthosis worn on the trunk. For example, the orthosis according to this embodiment may be a trunk orthosis that fixes the thoracolumbar spine with a first body and a second body, and fixes the lumbar spine with the first body alone. As another example, the orthosis according to this embodiment may be a trunk orthosis that fixes the trunk from the back to the sides with a first body and a second body, and fixes only the back with the first body alone.

[0083] The orthosis according to this embodiment may be a lower limb orthosis worn on the lower limb. For example, the orthosis according to this embodiment may be a lower limb orthosis in which the first and second main bodies fix the thigh from near the hip joint to the knee, ankle, and sole of the foot, and the first main body alone fixes the thigh from near the center to the knee and near the center of the lower leg. As another example, the orthosis according to this embodiment may be a lower limb orthosis in which the first and second main bodies fix the entire lower leg from the lower leg to the sole of the foot, and the first main body alone fixes the ankle-side half of the lower leg to the sole of the foot. The first main body may be further divisible so that the fixation range can be narrowed from the ankle-side half of the lower leg to near the ankle. As another example, the orthosis according to this embodiment may be a lower limb orthosis that fixes both sides of the ankle joint and the heel in a U-shape with a first body and a second body (the first body fixes the medial and lateral sides of the ankle joint and the second body fixes the heel), and fixes both sides of the ankle joint with only the first body (without fixing the heel).

[0084] As described above, the orthotic device according to this embodiment can be used in the treatment of multiple fixation sites or in treatment using multiple fixation methods, since the fixation range can be changed. Furthermore, the orthotic device can be used in the treatment of diseases in which the fixation range may change depending on the progress of treatment.

[0085] One example of a disease where the extent of fixation may change depending on the course of treatment is a distal radius fracture. In the treatment of a distal radius fracture, sugartong splint fixation may be performed in the initial stages (for example, two weeks after the fracture). Sugartong splint fixation is a method of fixing the palmar and dorsal sides of the affected area by attaching a splint that resembles a U shape. In the case of a distal radius fracture, the forearm, including the elbow, is fixed by sugartong splint fixation. As a result, flexion and extension of the elbow are restricted, and if fixation is continued for a long period of time, there is a risk of elbow contracture. Therefore, after about two weeks, the sugartong splint is removed and a new cast or splint is attached to fix the forearm excluding the elbow.

[0086] The orthosis according to this embodiment can be used, for example, in the treatment of distal radius fractures. That is, the orthosis may be, for example, an orthosis for the treatment of distal radius fractures. Initially, sugar tongue splint fixation can be performed by attaching the orthosis as shown in Figures 2A to 2D. Subsequently, forearm splint fixation can be performed by attaching the orthosis as shown in Figures 3A to 3C.

[0087] 1-7. Variations

[0088] A modified example of the orthosis 1 according to the first embodiment will now be described. The modified orthosis differs from the orthosis 1 according to the first embodiment described above in that the first body and the second body are integrally formed and separable. The following description will focus on the differences from the orthosis 1 according to the first embodiment, and other explanations will be omitted as necessary. Points that are not explained may be as described in 1-1 to 1-6 above.

[0089] In the modified orthosis according to this example, the first main body and the second main body are integrally formed. For example, in this modified example, the first base member 11 and base member 21 shown in Figure 1 may be formed from a single fabric, and the main cover member 153 and cover member 223 may be formed from a single fabric.

[0090] In this modified example, the integrally formed first body and second body are separable, preferably by cutting. The first body and second body are preferably formed from a material that can be cut by general-purpose cutting means such as scissors and a utility knife.

[0091] In this modified example, it is preferable that the first body has a first engaging portion and a second engaging portion (see Figure 5). As shown in the figure, when the second body is separated and only the first body is used, engaging the first engaging portion and the second engaging portion makes it less likely for the medical fixation material to protrude from the main containment area.

[0092] The orthotic device according to this modified example can reduce manufacturing costs compared to the orthotic device 1 according to the first embodiment. For example, in this modified example, at least a portion of the members of the connecting portion 30 in the first embodiment is unnecessary, so the orthotic device can be manufactured at a lower cost.

[0093] 2. Second Embodiment (Immobilization Device)

[0094] A fixation device according to a second embodiment of the present invention will now be described. The device according to this embodiment is a fixation device used to fix a part of the body, and includes the device according to the present invention and at least one medical fixation material. The device is as described in the first embodiment above, and that description also applies to this embodiment.

[0095] The above-mentioned at least one medical fixation material may be, for example, a medical fixation material described in the third embodiment described later, and that description also applies to this embodiment. Furthermore, the medical fixation material may be a medical fixation material known in the art. Examples of such known medical fixation materials include splints containing a curable resin that hardens with water, heat, or light. The shape and size of the medical fixation material may be appropriately adjusted according to the part and shape of the body to be fixed, the fixation area, and the fixation method.

[0096] 3. Third Embodiment (Medical Fixation Material)

[0097] 3-1. Overview of medical fixation materials

[0098] A medical fixation material according to a third embodiment of the present invention will now be described. The medical fixation material according to this embodiment is a medical fixation material for fixing a part of the body. This medical fixation material is used, for example, together with the orthotic device according to the first embodiment and the fixing orthotic device according to the second embodiment, and is attached to a part of the body by these orthotic devices. Alternatively, the medical fixation material according to this embodiment may be attached to a part of the body by an orthotic device, bandage, or sleeve (tubular retainer) known in the art.

[0099] The shape of a medical fixation material may be, for example, plate-like. In this specification, "plate-like" means a shape in which the length in the thickness direction is sufficiently shorter than the length in the surface direction. "Plate-like" is not limited to a form in which the surface is flat, but may include, for example, a form in which the surface is uneven, and a form in which the surface is sloped (a form in which there are parts of different thicknesses). Furthermore, "plate-like" is not limited to a rigid form in which bending and deformation do not occur, but may include, for example, semi-rigid and flexible forms in which bending or deformation may occur.

[0100] The shape of the medical fixation material is preferably a plate-like shape having a longitudinal direction and a transverse direction. That is, the shape of the medical fixation material is preferably a plate-like shape having a surface with a longitudinal direction and a transverse direction. In this specification, "longitudinal direction" refers to the relatively wider direction of the surface shape, and "transverse direction" refers to the relatively narrower direction of the surface shape. Shapes in which the longitudinal and transverse directions cannot be distinguished (e.g., square and circular shapes) may be considered as shapes having both a longitudinal and transverse direction and may be included in "shapes having a longitudinal and transverse direction". Furthermore, the shape of the surface may include, for example, shapes expressed by geometric shape terms (e.g., rectangular, trapezoidal, and elliptical shapes), shapes expressed by shape metaphors (e.g., star-shaped, heart-shaped, and crescent-shaped shapes), and other shapes (e.g., irregular shapes).

[0101] Furthermore, the shape of the medical fixation material preferably has corners or rounded corners. In the embodiments described later, a rectangular plate shape having a longitudinal direction and a transverse direction is exemplified, but the shape of the medical fixation material is not limited to such a plate shape. The shape of the medical fixation material may be appropriately selected according to the part of the body to which it is attached, the fixation area, the fixation strength, and the fixation method. The medical fixation material may have, for example, curved parts, bent parts, or notches formed to match the shape of the part of the body to which it is attached.

[0102] The medical fixation material according to this embodiment includes at least one fixing member and a covering member that covers the at least one fixing member.

[0103] The shape of the fixing member may be selected according to the shape of the medical fixation material. The fixing member may be, for example, plate-shaped, preferably plate-shaped with a longitudinal direction and a transverse direction. The fixing member may also have, for example, corners or rounded corners.

[0104] The shape of the covering member can be any shape that can cover the medical fixation material, for example, a sheet shape, preferably a sheet shape having a longitudinal direction and a transverse direction.

[0105] The fixing member includes a resin. The resin may be, for example, a water-curable resin, a photocurable resin, or a thermoplastic resin. The body part can be fixed by fixing the uncured fixing member to a part of the body and then curing the resin. Examples of water-curable resins include polyurethane prepolymer compositions consisting of a polyurethane prepolymer having isocyanate groups at the ends, obtained by reacting a polyol and a polyisocyanate, a catalyst, and other additives. Examples of photocurable resins include acrylate resins such as urethane (meth)acrylate resins. Examples of thermoplastic resins include polyester resins.

[0106] The above-mentioned resin may be included in the fixing member, for example, while being held by a substrate. That is, the fixing member may include a substrate that holds the above-mentioned resin. The substrate may be, for example, a base fabric. The base fabric may be various types of fabrics, such as knitted fabrics, woven fabrics, and nonwoven fabrics. Examples of fibers used in these various fabrics include one or more combinations selected from glass fibers, aramid fibers, polyester fibers, polyolefin fibers, polyamide fibers, polyacrylic fibers, rayon fibers, and cotton fibers. The above-mentioned base fabric is preferably formed using glass fibers in order to make the thickness of the fixing member thinner. The thinner thickness makes it easier to deform into a shape that conforms to the body, and as a result, the fixing force of the fixing member can be improved.

[0107] The covering member may be formed using various fabrics, such as knitted fabrics, woven fabrics, and nonwoven fabrics. Preferably, the covering member is made of a material that can be cut with general-purpose cutting means such as scissors and utility knives.

[0108] The medical fixation material according to this embodiment may include members other than the fixing member and the covering member. The medical fixation material may include, for example, a surrounding member that surrounds the end face of a plate-shaped fixing member. The surrounding member may have, for example, a coarse mesh structure and may be formed of, for example, a polyester nonwoven fabric. If the base fabric of the fixing member is made using glass fibers, providing a surrounding member can prevent glass fibers protruding from the end face of the fixing member from coming into contact with the body. Furthermore, by making the thickness of the surrounding member equal to or less than that of the fixing member, the unevenness in the thickness direction of the medical fixation material can be reduced. This can improve the fit to the body and the fixing force.

[0109] As the medical fixation material according to this embodiment, for example, the medical fixation material disclosed in Japanese Patent Application Publication No. 2018-183419 may be used. The surrounding member described above may be a member corresponding to the protective material (end protective material 13) disclosed in Japanese Patent Application Publication No. 2018-183419, for example.

[0110] 3-2. First aspect

[0111] The configuration of the medical fixation material 500 according to the first aspect of the third embodiment will be described with reference to Figures 9A and 9B. Figures 9A and 9B are schematic diagrams showing the medical fixation material 500. Figure 9A is a plan view of the medical fixation material 500. Figure 9B is a schematic diagram of the medical fixation material 500 shown in Figure 9A viewed from the direction of arrow D1. However, in Figure 9B, modifications have been made to make the configuration easier to understand, such as widening the gap between contacting members and separating members that are originally joined together.

[0112] The medical fixation material 500 includes two or more adjacent fixing members 510 spaced apart from each other, and a covering member 520 that covers the two or more fixing members 510. The separation portion 590 located between the two or more adjacent fixing members 510 is cuttable.

[0113] In Figures 9A and 9B, the medical fixation material 500 is a rectangular plate with a longitudinal direction and a transverse direction. The longitudinal direction of the medical fixation material 500 is the left-right direction in the figure. In the same figure, as an example of two or more fixing members 510, a first fixing member 511 and a second fixing member 512 are shown, each having a rectangular plate shape with a longitudinal direction and a transverse direction. The first fixing member 511 and the second fixing member 512 have the same length in the transverse direction, but their longitudinal lengths are different. The covering member 500 is a rectangular sheet with a longitudinal direction and a transverse direction.

[0114] The first fixing member 511 and the second fixing member 512 are spaced apart from each other, with their short sides facing each other, and adjacent in the left-right direction. The first fixing member 511 is located to the left of the second fixing member 512.

[0115] In Figure 9B, two covering members are shown as an example of the covering member 520, specifically a first covering member 521 and a second covering member 522. The first covering member 521 covers the upper side of the fixing member 510. The second covering member 522 covers the lower side of the fixing member 510. The peripheral edges of the first covering member 521 and the second covering member 522 are joined together. This joining may be done by bonding with adhesive or double-sided tape, or by welding with ultrasonic welding, for example. The joined portion may be a part or all of the peripheral edge. Note that in Figure 9B, the peripheral edges of the first covering member 521 and the second covering member 522 are depicted as separated and not joined together.

[0116] The size of the medical fixation material 500, that is, the size of the fixing members 510 (first fixing member 511 and second fixing member 512) and the covering members 520 (first covering member 521 and second covering member 522), may be appropriately selected according to the part of the body to which it is attached, the area of ​​fixation, the strength of fixation, and the method of fixation.

[0117] In the separation portion 590 located between the adjacent first fixing member 511 and second fixing member 512, the covering members 520 may be joined together, for example, the first covering member 521 and the second covering member 522 may be joined together. As shown in Figure 9, the separation portion 590 is formed in the short direction of the medical fixing material 500. By joining the covering members 520 together in the separation portion 590, displacement of the first fixing member 511 and the second fixing member 512 can be suppressed. In the separation portion 590, the first covering member 521 and the second covering member 522 may be bonded together, for example, by adhesive or double-sided tape, or welded together by ultrasonic welding. Note that in Figure 9B, the covering members 520 are depicted separated and not joined together in the separation portion 590.

[0118] The shape of the separation portion 590 may be straight, as shown in Figure 9A, or it may be a curved or wave-shaped or other shape. Also, the shape of the separation portion 590 may be parallel to the shorter direction, as shown in the same figure, or it may not be parallel. The shape of the separation portion 590 is adjusted by changing the shape of the fixing member adjacent to the separation portion 590.

[0119] The number of separation portions 590 may be one or more, as shown in Figures 9A and 9B. The number of separation portions 590 can be adjusted by changing the number of fixing members.

[0120] The separation portion 590 is configured to be cut. Preferably, the separation portion 590 is configured to be cut by general-purpose cutting means such as scissors and utility knives. The dashed lines (dotted lines) on the separation portion 590 shown in Figures 9A and 9B show an example of a cuttable portion. Since the separation portion 590 does not include the fixing member 510, it can be cut without using a special tool such as a plaster cutter, even after the fixing member 510 has hardened. Furthermore, if the covering members 520 (first covering member 521 and second covering member 522) are joined together in the separation portion 590, the first fixing member 511 and the second fixing member 512 will not be exposed from the cut surface after the separation portion 590 is cut. That is, even after cutting, the state in which the first fixing member 511 and the second fixing member 512 are covered by the covering member 520 is maintained.

[0121] Figures 9A and 9B illustrate a configuration in which the covering members 520 are joined together (i.e., the first covering member 521 and the second covering member 522 are joined) for the separation portion 590, but the configuration of the separation portion 590 is not limited to this. For example, the separation portion 590 may be formed by joining the first covering member 521 and the second covering member 522 to another member positioned between them (i.e., the first covering member 521 and the second covering member 522 are indirectly joined). This other member may be, for example, the surrounding member described in 3-1 above (e.g., the protective material disclosed in Japanese Patent Application Publication No. 2018-183419). That is, in the separation portion 590, part or all of the surrounding member may be joined to the covering member 520. This joining may be, for example, by bonding with an adhesive or double-sided tape, or by welding by ultrasonic welding. In this case, the surrounding member is preferably formed from a material that can be cut by general-purpose cutting means such as scissors and utility knives.

[0122] The fixation range and strength of medical fixation materials can vary depending on the area of ​​the medical fixation material attached to the body. If it is desired to change the fixation range or strength after the fixation material has hardened, for example, the fixation material can be cut and a portion removed. However, the fixation material is very hard after hardening. In the case of conventional medical fixation materials that do not have a cuttable portion like the separation portion 590 mentioned above, a special tool such as a plaster cutter is required for cutting. Therefore, if it is desired to change the fixation range or strength of conventional medical fixation materials after hardening, it is necessary to cut the fixation material with a special tool and then remove a portion or all of the medical fixation material. If the entire medical fixation material is removed, a new medical fixation material with a different fixation range or strength will need to be attached. Thus, with conventional medical fixation materials, it is not easy to change the fixation range or strength by cutting. Furthermore, even if it is possible to cut it, there is a risk that the fixation material will be exposed from the cut surface. In this case, when a medical fixation material is applied to the body after a portion has been removed to reduce the area of ​​fixation, depending on the material of the fixation material, the exposed fixation material from the cut surface may irritate the skin. Also, some patients may be frightened by the vibration and sound of the cast cutter used to cut the fixation material.

[0123] In contrast, the medical fixation material 500 according to the first embodiment has a severable separation portion 590 formed between the first fixation member 511 and the second fixation member 512. Therefore, the fixation range and fixation strength can be easily changed by cutting the separation portion 590 and then removing the first fixation member 511 or the second fixation member 512. Thus, for example, the fixation range and fixation strength can be easily and appropriately adjusted according to the progress of treatment. It is also possible to configure the fixation member 510 so that it is not exposed from the cut surface after the separation portion 590 is cut, in which case the skin irritation described above is less likely to occur. In addition, since it is not necessary to use a cast cutter when cutting, it is less likely to cause psychological burden on the patient.

[0124] The medical fixation material 500 according to the first embodiment can be used, for example, in the treatment of distal radius fractures. The general flow of the treatment is as follows: The medical fixation material 500 is placed in the first fixation material holder 15 and the second fixation material holder 22 of the orthosis 1 shown in Figure 1. Then, as shown in Figures 2A to 2D, the fixation orthosis including the orthosis 1 and the medical fixation material 500 is attached to the forearm, including the elbow. After attachment, the fixation member 510 is hardened. This allows for sugar tongue splint fixation. After about two weeks, the fixation orthosis is removed and the medical fixation material 500 is taken out. The separation portion 590 of the medical fixation material 500 is cut and the fixation member that was attached to the elbow is removed. After removing the second main body 20 from the orthosis 1, the fixing member that was attached to the part other than the elbow is housed in the first fixing member holding part 15 of the first main body 10, and the device is attached to the forearm excluding the elbow as shown in Figures 3A to 3C. This allows for forearm splinting. In addition, medical fixing material may be continuously housed in the third fixing member holding part 16 of the first main body 10 from the start of treatment. That is, in sugar tongue splinting and forearm splinting, other medical fixing material held by the third fixing member holding part 16 may be used.

[0125] 3-3. Second aspect

[0126] The configuration of the medical fixation material 600 according to the second aspect of the third embodiment will be described with reference to Figures 10A and 10B. Figures 10A and 10B are schematic diagrams showing the medical fixation material 600. Figure 10A is a plan view of the medical fixation material 600. Figure 10B is a schematic diagram of the medical fixation material 600 shown in Figure 10A viewed from the direction of arrow D2. However, in Figure 10B, modifications have been made to make the configuration easier to understand, such as widening the gap between contacting members and separating members that are originally joined together.

[0127] The medical fixation material 600 according to the second embodiment has a similar structure to the medical fixation material 500 according to the first embodiment, but differs in that the separation portion 690 is formed in the longitudinal direction of the medical fixation material 600. The following explanation will focus on the differences from the first embodiment, and other explanations will be omitted as necessary. Points that are not explained may be the same as those in the first embodiment, and the explanations in the first embodiment above also apply to the second embodiment.

[0128] The medical fixation material 600 includes two or more fixing members 610 that are spaced apart from each other and adjacent to one another, and a covering member 620 that covers the two or more fixing members 610. The separation portion 690 located between the two or more adjacent fixing members 610 is cuttable. Figures 10A and 10B show a first fixing member 611 and a second fixing member 612 as examples of the two or more fixing members 610. Figure 10B shows a first covering member 621 and a second covering member 622 as examples of the covering member 620.

[0129] The first fixing member 611 and the second fixing member 612 are spaced apart from each other, with their longer sides facing each other, and adjacent in the vertical direction. The first fixing member 611 is located above the second fixing member 612.

[0130] A separable separation portion 690 is formed between the adjacent first fixing member 611 and second fixing member 612. The separation portion 690 is formed in the longitudinal direction of the medical fixing member 600.

[0131] Because the separation portion 690 is formed in the longitudinal direction, the medical fixation material 600 has the advantage of being easy to remove from the body when it has hardened into a tubular shape on the body. Specifically, this is as follows: For example, when a conventional long medical fixation material is attached along the forearm, the medical fixation material hardens and is attached in a shape that wraps around the forearm. When removing the medical fixation material from the forearm, it is necessary to cut the medical fixation material with a special tool such as a cast cutter. In contrast, in the case of the medical fixation material 600 according to the second embodiment, in which a separation portion 690 that can be cut in the longitudinal direction is formed, the separation portion 690 is not hardened, so the medical fixation material 600 can be removed without cutting it with a special tool as in the conventional case. In addition, the medical fixation material 600 can be divided in the longitudinal direction by cutting the separation portion 690 with a general-purpose cutting means. That is, the medical fixation material 600 can be divided along the forearm. By opening the medical fixation material 600 from the separated portion, the medical fixation material 600 can be removed more easily from the forearm. Furthermore, by cutting the separation portion 690 in this way, a portion of the medical fixation material 600 can be reused. For example, in the case of a medical fixation material that wraps around the forearm from the palmar side through the radial side to the dorsal side and has a separation portion formed on the radial side, only the palmar side can be reused by cutting the separation portion.

[0132] The configuration of the second embodiment may be combined with, for example, the configuration of the first embodiment. Specifically, in the medical fixation material according to this embodiment, two or more separation portions may be formed in the longitudinal and transverse directions of the medical fixation material. Therefore, in the medical fixation material according to this embodiment, the separation portions may be formed in the longitudinal and / or transverse directions.

[0133] 3-4. Third aspect

[0134] Referring to Figure 11, the configuration of the medical fixation material 700 according to the third aspect of the third embodiment will be described. Figure 11 is a schematic diagram of the medical fixation material 700 viewed from the thickness direction. However, in Figure 11, modifications have been made to make the configuration easier to understand, such as widening the spacing between contacting members and separating members that are originally joined. The following description will focus on the differences from the first aspect, and other explanations will be omitted as necessary. Points that are not explained may be the same as those in the first aspect, and the explanation in the first aspect above also applies to the third aspect.

[0135] The medical fixation material according to the third embodiment is composed of two or more medical fixation materials combined together. Therefore, the medical fixation material according to the third embodiment will also be referred to below as "a set of medical fixation materials". Each of the two or more medical fixation materials includes one fixing member and a covering member that covers the one fixing member. The two or more medical fixation materials can be held in an overlapping state by an orthotic device (for example, the fixation material holding portion of the orthotic device according to the first embodiment).

[0136] Figure 11 shows a first medical fixation material 701 and a second medical fixation material 702 as examples of two or more medical fixation materials. The first medical fixation material 701 includes one fixing member 710 and a covering member 720 that covers the fixing member 710. The covering member 720 includes a first covering member 721 that covers the upper side of the fixing member 710 and a second covering member 722 that covers the lower side of the fixing member 710. The second medical fixation material 702 includes one fixing member 730 and a covering member 740 that covers the fixing member 730. The covering member 740 includes a first covering member 741 that covers the upper side of the fixing member 730 and a second covering member 742 that covers the lower side of the fixing member 730.

[0137] The first medical fixation material 701 and the second medical fixation material 702 are stacked on top of each other. Specifically, the first medical fixation material 701 is stacked on top of the second medical fixation material 702. Between the second covering member 722 of the first medical fixation material 701 and the first covering member 741 of the second medical fixation material 702, a bonding layer 790 may be provided to detachably join the first medical fixation material 701 and the second medical fixation material 702. That is, in a set of medical fixation materials according to the third embodiment, preferably, the stacked medical fixation materials are detachably joined to each other. The bonding layer 790 may be formed, for example, by an adhesive or double-sided tape. The bonding layer 790 can suppress misalignment of the stacked first medical fixation material 701 and the second medical fixation material 702.

[0138] The two or more medical fixation materials (first medical fixation material 701 and second medical fixation material 702) that constitute a set of medical fixation materials 700 may preferably be plate-shaped, each having a longitudinal direction and a transverse direction. In this case, the longitudinal lengths of the two or more medical fixation materials may be different from each other. Also, the longitudinal lengths of at least two of the medical fixation materials may be the same. Similarly, the transverse lengths of the two or more medical fixation materials may be different from each other. Also, the transverse lengths of at least two of the medical fixation materials may be the same. Thus, the sizes of the two or more medical fixation materials may be different from each other, some may be different from each other, or may all be the same.

[0139] A set of medical fixation devices 700, which consists of two or more medical fixation devices stacked on top of each other, allows for easy adjustment of the fixation strength. The fixation strength of a set of medical fixation devices 700 can increase as the number of stacked medical fixation devices increases. For example, the fixation strength can be reduced by removing some of the medical fixation devices from a set of medical fixation devices 700. Therefore, by using a set of medical fixation devices 700, the fixation strength can be easily and appropriately adjusted according to the progress of treatment.

[0140] Furthermore, a set of medical fixation devices 700, which consists of two or more medical fixation devices that differ in some or all of their sizes, allows for easy modification of the fixation area. For example, the fixation area can be narrowed by removing some of the medical fixation devices from a set of medical fixation devices 700. Therefore, by using a set of medical fixation devices 700, the fixation area can be easily and appropriately adjusted according to the progress of treatment.

[0141] 3-5. The fourth aspect

[0142] The configuration of the medical fixation material 800 according to the fourth aspect of the third embodiment will be described with reference to Figure 12. Figure 12 is a schematic diagram of the medical fixation material 800 viewed from the thickness direction. However, in Figure 12, modifications have been made to make the configuration easier to understand, such as widening the spacing between contacting members and separating members that are originally joined. The following explanation will focus on the differences from the first and third aspects, and other explanations will be omitted as necessary. Points that are not explained may be the same as those in the first and third aspects, and the explanations in the first and third aspects above also apply to the fourth aspect.

[0143] The medical fixation material according to the fourth embodiment is composed of two or more medical fixation materials combined together. Therefore, the medical fixation material according to the fourth embodiment will also be referred to below as "a set of medical fixation materials". Each of the two or more medical fixation materials includes one fixing member and a covering member that covers the one fixing member. At least one of the two or more medical fixation materials is held by an orthotic device (for example, the fixation material holding part of the orthotic device according to the first embodiment) in a state where it is stored inside the other medical fixation materials. The covering member of the other medical fixation material preferably has an opening from which the at least one medical fixation material can be removed. This makes it possible to remove the stored medical fixation material without cutting the covering member.

[0144] Figure 12 shows a first medical fixation material 801 and a second medical fixation material 802 as examples of two or more medical fixation materials. The first medical fixation material 801 includes one fixing member 810 and a covering member 820 that covers the fixing member 810. The covering member 820 includes a first covering member 821 that covers the upper side of the fixing member 810 and a second covering member 822 that covers the lower side of the fixing member 810. The second medical fixation material 802 includes one fixing member 830 and a covering member 840 that covers the fixing member 830. The covering member 840 includes a first covering member 841 that covers the upper side of the fixing member 830 and a second covering member 842 that covers the lower side of the fixing member 830.

[0145] The second medical fixation material 802 is housed inside the first medical fixation material 801. Specifically, the second medical fixation material 802 is housed between the fixing member 810 and the covering member 820 of the first medical fixation material 801. In this case, a portion of the covering member 820 (first covering member 821 and / or second covering member 822) of the first medical fixation material 801 preferably has an opening. This opening is formed to allow the second medical fixation material 802 to be removed.

[0146] In the medical fixation material shown in Figure 12, an additional covering member may be provided between the second covering member 842 and the fixing member 810. This makes it less likely for the second medical fixation material 802 to stick to the resin contained in the fixing member 810. As a result, the second medical fixation material 802 becomes easier to peel off and remove.

[0147] A set of medical fixation devices 800, in which at least one of two or more medical fixation devices is housed inside the other medical fixation devices, allows for easy adjustment of the fixation strength. The fixation strength of a set of medical fixation devices 800 can increase as the number of stacked medical fixation devices increases. For example, the fixation strength can be reduced by removing some of the medical fixation devices from a set of medical fixation devices 800. Therefore, by using a set of medical fixation devices 800, the fixation strength can be easily and appropriately adjusted according to the progress of treatment.

[0148] A set of medical fixation devices 800, composed of two or more medical fixation devices that differ in some or all of their sizes, allows for easy modification of the fixation area. For example, the fixation area can be narrowed by removing some of the medical fixation devices from the set 800. Therefore, by using a set of medical fixation devices 800, the fixation area can be easily and appropriately adjusted according to the progress of treatment.

[0149] In a set of medical fixation materials 800, the sizes of two or more medical fixation materials may be different from each other, partially different from each other, or all the same, as described in the medical fixation material 700 according to the third embodiment above.
