Description

Technical Field

[0001] The present disclosure relates to a patch attachment material for attaching a patch to an auxiliary tool used when attaching a patch to an affected area.

Background Art

[0002] For affected areas that are difficult to reach, such as the back, a wet compress applicator used by a user to apply a wet compress alone has been proposed. This wet compress applicator includes an auxiliary tool (storage part) provided with a handle and an elastic member attached to the auxiliary tool. The user holds the handle of the auxiliary tool with the back surface (the surface opposite to the drug surface) of the wet compress attached to the elastic member, transports the wet compress applicator to the affected area on the back, and then, for example, sandwiches the elastic member between the backrest of a chair and the back to attach the drug surface of the adhesive wet compress to the affected area (Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the wet compress applicator of Cited Document 1, a wet compress holding layer made of a fluffy fiber material is provided on the elastic member, and the back surface of the wet compress is bitten into this wet compress holding layer to hold the wet compress. Generally, a protective cover made of a thin film such as polyethylene or cellophane is provided on the drug surface of the adhesive wet compress. On the other hand, in the wet compress applicator of Cited Document 1, when the protective cover is peeled off from the drug surface of the wet compress with the back surface of the wet compress attached to the wet compress holding layer of the elastic member, there is a risk that the wet compress will be pulled by the protective cover and detached from the elastic member. Further, when the holding force of the wet compress on the wet compress holding layer is increased, there is a risk that the wet compress will not peel off from the wet compress applicator after the user transports the wet compress applicator to the affected area on the back and attaches the drug surface to the affected area.

[0005] The object of the present invention is to provide an adhesive patch attachment material that, when temporarily fixing an adhesive patch to an auxiliary device, allows only the protective cover to be peeled off the adhesive patch while the patch is attached to the auxiliary device via the adhesive patch attachment material, and after the adhesive patch has been applied to the affected area, allows the adhesive patch to peel off the attachment material, leaving only the adhesive patch on the back. [Means for solving the problem]

[0006] The present invention relates to a patch attachment material for attaching a patch to an auxiliary device for applying the patch to an affected area, characterized in that it has a base material comprising a base portion attached to the auxiliary device and a patch attachment portion extending from the base portion in an angle-adjustable manner, and one side of the patch attachment portion is provided with a first adhesive surface that adheres to the patch. [Effects of the Invention]

[0007] According to the present invention, when a protective cover is peeled off a patch while the first adhesive surface, which is angle-adjustable relative to the base, is attached to the patch, even if the patch is deformed by being pulled by the protective cover, the patch attachment part can change its angle in sync with the deformation of the patch and follow the patch. This allows the adhesion between the first adhesive surface and the patch to be maintained until the protective cover is peeled off. Therefore, the protective cover can be peeled off while the patch remains attached to the support without increasing the adhesive strength of the first adhesive surface too much. On the other hand, when the patch attachment material is moved away from the back after the patch has been attached, the angle of the patch attachment material is changed, which changes the adhesion between the patch and the first adhesive surface from surface adhesion to linear adhesion, making them easier to separate (peel off) with less force, so that only the patch can be left on the back.

Embodiments for Carrying out the Invention

[0009] Hereinafter, embodiments of a patch attachment material according to the present invention will be described in detail with reference to the drawings.

[0010] In FIG. 1, a wearing device 1 as an assistive tool is worn by a user who tries to attach a patch such as a wet compress to an affected area on the back that is difficult to reach with the hand. The wearing device 1 is formed based on, for example, a vest (waistcoat) made of a fiber material, and has a left front part 2, a right front part 3, a left shoulder part 4, a right shoulder part 5, a collar part 6, a left cuff 7, a right cuff 8, a back part 9, etc. The left front part 2 and the right front part 3 cover the front (abdomen) of the user, the left shoulder part 4 abuts on the left shoulder of the user, and the right shoulder part 5 abuts on the right shoulder of the user. A collar part 6 surrounding the user's neck is formed between the left shoulder part 4 and the right shoulder part 5. The left cuff 7 is inserted with the user's left arm, and the right cuff 8 is inserted with the user's right arm.

[0011] The back panel 9 faces the left front panel 2 and the right front panel 3 in the front-to-back direction and covers the user's back. A rectangular opening 9A is formed in the center of the back panel 9 in the left-to-right direction, penetrating in the front-to-back direction. The opening 9A is formed in the back panel 9 in the area corresponding to the affected area on the user's back, for example, an area that is difficult for the user to reach with their hands. A drug attachment surface 10 is positioned in the opening 9A of the back panel 9.

[0012] The medication attachment surface 10 is positioned at the opening 9A of the back panel 9 and constitutes a part of the back panel 9. The medication attachment surface 10 is made of a rectangular thin film formed transparent or translucent using, for example, a resin material, and is fixed to the periphery of the opening 9A by means of adhesion or sewing. In other words, the medication attachment surface 10 is the area of ​​the back panel 9 of the wearable device 1 that corresponds to the affected area on the back. The second adhesive surface 13 of the patch attachment tape 11, which will be described later, is adhered to the inner surface 10A of the medication attachment surface 10.

[0013] The adhesive patch attachment tape 11 of the present invention, as an adhesive patch attachment material, is placed between the medication attachment surface 10 provided on the wearer 1 and the adhesive patch 101 described later, and attaches and holds the adhesive patch 101 to the wearer 1. As shown in Figures 4 and 5, the adhesive patch attachment tape 11 has a base material 11A formed in the shape of a tape (strip or flat plate) using a flexible material that has appropriate elasticity and is deformable, such as vinyl, an adhesive surface 11B provided on only one of the front and back surfaces of the base material 11A, and a non-adhesive surface 11C provided on the other surface of the base material 11A. The base material 11A has a base portion 11E that is attached to the wearer 1, sandwiching a folded portion 11D shown by a dashed line in Figure 5, and an adhesive patch attachment portion 11F that extends from the base portion 11E at an angle that can be changed. The base material 11A is preferably a flexible material with moderate elasticity and deformability, such as resin or thin metal, but it is not necessarily limited to these materials and may be made of paper or other materials that do not have elasticity.

[0014] The adhesive patch attachment tape 11 is formed as a double-folded tape by folding the base portion 11E and the non-adhesive surface 11C of the adhesive patch attachment portion 11F facing each other, with the folded portion (hinge portion) 11D of the base material 11A as the center. The adhesive surface 11B, which is folded in half with the folded portion 11D as the center, is divided into a first adhesive surface 12 on the adhesive patch attachment portion 11F side and a second adhesive surface 13 on the base portion 11E side, with the folded portion 11D as the boundary. The first adhesive surface 12 is adhered to the back surface 101B of the adhesive patch 101, and the second adhesive surface 13 is adhered to the medication attachment surface 10 of the wearer 1. Furthermore, since the non-adhesive surface 11C is not adhesive, the adhesive patch attachment tape 11 opens and closes like a hinge, with the folded portion 11D as the center, between a closed position (position in Figure 7) where the non-adhesive surfaces 11C are in contact with or close to each other, and an open position (position in Figure 8) where they are separated from each other. The angle between the base portion 11E and the adhesive patch attachment portion 11F can be changed.

[0015] Here, the first adhesive surface 12 is composed of a plurality of triangular adhesive pieces 12A that are continuous in a sawtooth pattern along the length. The plurality of adhesive pieces 12A constituting the first adhesive surface 12 have their base on the folded portion 11D side of the adhesive patch attachment tape 11, and the width, which is the length in the direction perpendicular to the axis in the direction away from the folded portion 11D, gradually decreases as they move away from the folded portion 11D. Also, the tip of the adhesive piece 12A is a triangular corner and has a pointed shape. As a result, the area of ​​the first adhesive surface 12 gradually decreases as it moves away from the folded portion 11D of the base material 11A, and the area of ​​the first adhesive surface 12 is set to be smaller on the side away from the folded portion 11D of the base material 11A than on the side with the folded portion 11D. Note that the plurality of adhesive pieces constituting the first adhesive surface 12 are not limited to a triangular shape; for example, a trapezoidal shape or other shape where the area gradually decreases as it moves away from the folded portion 11D of the base material 11A is desirable, but a rectangular shape or the like is also acceptable.

[0016] The second adhesive surface 13 is located on the opposite side of the first adhesive surface 12, with the folded portion 11D of the base material 11A in between. The second adhesive surface 13 has a rectangular shape extending in the longitudinal direction of the base material 11A, and its entire surface is adhesive. This adhesive patch attachment tape 11 can be easily manufactured by cutting a single resin substrate with adhesive on one side into the shape shown in Figure 5 and folding it back at the folded portion 11D.

[0017] As shown in Figure 4, the adhesive patch attachment tape 11 attaches and holds the adhesive patch 101 to the medication attachment surface 10 of the wearer 1. The adhesive patch 101 is formed in the shape of a rectangular sheet with medication and adhesive on one side of a stretchable support such as nonwoven fabric. As a result, one side of the adhesive patch 101 becomes the adhesive medication surface 101A, and by attaching this medication surface 101A to the affected area, the medication (active ingredient) is supplied to the affected area. The back side 101B of the adhesive patch 101, which is opposite to the medication surface 101A, is adhered to the first adhesive surface 12 of the adhesive patch attachment tape 11. In addition, the medication surface 101A of the adhesive patch 101 is provided with three protective covers (release films) 101C made of thin films such as polyethylene or cellophane. Note that the protective covers are not limited to three, but may consist of two or four or more.

[0018] Furthermore, the patch 101 can be of any kind, for example, a so-called poultice in which an ointment containing an active ingredient and moisture is applied to a thick nonwoven fabric, or a tape in which the active ingredient is applied to a thin, stretchable knit. In addition, some patches are composed of a non-stretchable support, and the patch attachment tape 11 can also be used with these.

[0019] Next, the process of attaching the adhesive patch 101 to the medication attachment surface 10 using the adhesive patch attachment tape 11, and then peeling off the protective cover 101C from the adhesive patch 101, will be explained with reference to Figures 7 to 9.

[0020] When attaching the patch 101 to the medication attachment surface 10 of the device 1, the second adhesive surfaces 13 of the two patch attachment tapes 11 are adhered to the positions on the medication attachment surface 10 corresponding to the longitudinal end 101D of the patch 101. Then, the back surface 101B of the patch 101 on the end 101D side is adhered to the first adhesive surface 12 of the patch attachment tape 11. Alternatively, the patch attachment tape 11 may be adhered to the patch 101 first, and then attached to the medication attachment surface 10. This makes alignment easier. After attaching the patch 101 to the medication attachment surface 10 in this manner, the protective cover 101C is peeled off from the medication surface 101A of the patch 101.

[0021] As shown in Figures 6 and 7, when removing the protective cover 101C, the end 101C1 of the protective cover 101C, located in the center of the length of the patch 101, is grasped and pulled laterally (in the direction of arrow F1) (let the pulling force at this time be f1). The tensile force f1 acts as a force that stretches the patch 101 via the adhesive force (let the adhesive force A) of the medicated surface 101A of the patch. On the other hand, since the left end of the patch 101 in the figure is fixed, a force (restoring force) that tries to contract due to the elasticity of the patch 101 is generated simultaneously with the tensile force f1. The force due to the tensile force f1 and the restoring force exceeds the adhesive force A, and the adhesion between the protective cover 101C and the medicated surface 101A of the patch is detached. The peel line where the protective cover 101C and the drug surface 101A of the patch separate corresponds to the common point of application of the tensile force f1 and the restoring force. As the protective cover 101C moves in the direction of F1, the peel line moves continuously along the adhesive surface between the protective cover 101C and the drug surface 101A, causing the protective cover 101C to peel off. Depending on the user's operation, the protective cover 101C may move in a U-shape to a J-shape or like opening a fan, so the peel line is always located above and away from the drug attachment surface 10. As the peeling of the protective cover 101C progresses and the peel line approaches the end 101D of the patch 101, the protective cover 101C gradually moves away from the drug attachment surface 10, as shown in Figures 7 and 8.

[0022] As the protective cover 101C is further peeled off, as shown in Figure 8, the protective cover 101C attempts to rise from the drug attachment surface 10 due to its restoring force, causing the gap between the end 101C1 and the drug attachment surface 10 (the gap between the peel line and the drug attachment surface 10) to increase further. As a result, the end 101C1 of the protective cover 101C is pulled diagonally upward (in the direction of arrow F2), and the adhesive patch 101 is lifted on the end 101D side and deformed into a mountain shape.

[0023] At this time, the adhesive patch attachment tape 11 can be deformed into an open position like a hinge centered on the folded portion 11D (an open position where the non-adhesive surfaces 11C are separated from each other), so that the gap between the end portion 101C1 and the medication attachment surface 10 is filled, and the first adhesive surface 12 can follow the back surface 101B of the patch 101 due to its own adhesive force, and adhesion between the first adhesive surface 12 of the adhesive patch attachment tape 11 and the back surface 101B of the patch 101 can be maintained.

[0024] As the protective cover 101C continues to peel, and the peel line reaches a position corresponding to the adhesive attachment tape 11 on the back surface of the adhesive patch 101, as shown in Figure 10, the multiple adhesive pieces 12A constituting the first adhesive surface 12 of the adhesive attachment tape 11 will bite into the back surface 101B of the adhesive patch 101 with the vertices of their respective triangles. At this point, the common point of application of the tensile force f1 and the restoring force shifts from the peel line to the bitten portion. At this time, the restoring force of the adhesive patch 101 acts using the bitten portion as a foothold, and acts in a direction that closes the adhesive attachment tape 11 like a hinge centered on the folded portion 11D (in a direction in which the non-adhesive surfaces 11C move closer to each other). As a result, the adhesion between the remaining protective cover 101C and the medicated surface 101A of the patch changes from surface adhesion to linear adhesion. Since linear adhesion has weaker adhesive strength than surface adhesion, the two can be separated with less force, and combined with the tensile force f1, only the protective cover 101C can be easily peeled off.

[0025] On the other hand, in an environment where the aforementioned indentation portion is maintained, the radius of the hinge-like opening and closing motion of the adhesive patch attachment tape 11 with the folded portion 11D as the axis of rotation is constant. Therefore, almost no external force acts on the adhesive surface between the back surface 101B of the adhesive patch 101 and the first adhesive surface 12, and the adhesion between the two is maintained by the adhesive force of the first adhesive surface 12 itself. In this way, as shown in Figure 9, the adhesion between the back surface 101B on the end 101D side of the adhesive patch 101 and the first adhesive surface 12 of the adhesive patch attachment tape 11 is maintained, and only one protective cover 101C can be peeled off from the medicinal surface 101A of the adhesive patch 101.

[0026] Furthermore, when the user pulls the protective cover 101C in the direction of F1 or F2, a force equivalent to that force f1 also acts on the adhesive tape 11 on the opposite side. However, since the adhesive tape 11 on the opposite side can be opened and closed like a hinge in accordance with the inclination angle of the adhesive 101, the direction (angle) in which the force equivalent to f1 acts is almost parallel to the first adhesive surface 12 of the adhesive tape 11 on the opposite side. As a result, the first adhesive surface 12 of the adhesive tape 11 on the opposite side can maintain surface adhesion, and its adhesive strength is hardly weakened.

[0027] However, it is desirable that the external force acting on the adhesive patch attachment tape 11 on the opposite side is blocked. Furthermore, the shorter the total length that the adhesive patch 101 is stretched from its stationary state, the smaller the deformation of the adhesive patch 101 into a mountain shape, the earlier the timing at which the adhesive piece 12A bites into the vertex of the triangle, and the easier it is for the formed bitten portion to be maintained. For this reason, when the user peels off the protective cover 101C, it is desirable to press down on the central protective cover 101C of the three protective covers 101C in the direction of the downward arrow F3 in Figure 9 with a finger or other means. In particular, when peeling off the second protective cover 101C (left side in the figure) after peeling off the first protective cover 101C in Figure 9, the adhesive patch 101 will be stretched as a whole, and the deformation of the adhesive patch 101 into a mountain shape will be greater, so it is desirable to press down on the central protective cover 101C of the three protective covers 101C in the direction of the downward arrow F3 in Figure 9 with a finger or other means. If there are two protective covers 101C, or when removing the last protective cover 101C, you may use a rod-shaped object that is not easily adhesive to hold it down.

[0028] Normally, when peeling the protective cover 101C from the medicated surface 101A, the patch 101 may sag due to its own elasticity, and sometimes the medicated surfaces 101A may bend and stick together. However, in this embodiment, the elastic patch attachment tape 11 curves in a C-shape near the folded portion 11D, so that the patch 101 always remains stretched and does not sag. As a result, the patch 101 can be held in the correct position on the medicated surface 10 of the device 1 using the patch attachment tape 11. In this way, after peeling one protective cover 101C from the medicated surface 101A of the patch 101, the other protective cover 101C can be peeled off using the same procedure as described above.

[0029] Next, as a comparative example of the adhesive patch attachment tape 11 according to this embodiment, the case in which the adhesive patch 101 is attached to the medication attachment surface 10 using double-sided tape 102, and then the protective cover 101C is peeled off from the adhesive patch 101, will be described with reference to Figure 11.

[0030] The double-sided tape 102 has adhesive surfaces on both sides of the tape-shaped base material. One adhesive surface 102A is adhered to the drug attachment surface 10 of the wearable device 1, and the other adhesive surface 102B is adhered to the back surface 101B of the patch 101.

[0031] As shown in Figure 11(A), when the end 101C1 of the protective cover 101C is pinched and peeled off from the drug surface 101A of the patch 101, the protective cover 101C tries to stand up from the drug attachment surface 10 due to its restoring force, so the gap between the end 101C1 and the drug attachment surface 10 increases. As a result, the end 101C1 of the protective cover 101C is pulled diagonally upward (in the direction of arrow F2), and the patch 101 is lifted on the end 101D side and deformed into a mountain shape.

[0032] In this case, the adhesive surface 102A of the double-sided tape 102 is in surface contact with the drug attachment surface 10 over its entire surface, so the adhesive surface 102B forms almost the same plane as the drug attachment surface 10. Here, the adhesive surface 102A of the double-sided tape 102 and the drug attachment surface 10 are made of resin material, and the protective cover 101C, which is also made of resin material, is adhered to the drug surface 101A of the smooth and adhesive patch 101. On the other hand, the back surface 101B of the patch 101 is made of nonwoven fabric. Therefore, the adhesive force between the adhesive surface 102A and the drug attachment surface 10 and the adhesive force between the protective cover 101C and the drug surface 101A of the patch 101 are greater than the adhesive force between the adhesive surface 102B of the double-sided tape 102 and the back surface 101B (nonwoven fabric) of the patch 101. Therefore, when force is applied to peel the protective cover 101C from the adhesive patch 101, the force acts in a perpendicular direction (away from each other), causing the adhesive surface 102B of the double-sided tape 102, which is the weakest of the three, to easily peel off from the back surface 101B (nonwoven fabric) of the adhesive patch 101, and the end 101D side of the adhesive patch 101 lifts away from the medication attachment surface 10.

[0033] As a result, as shown in Figure 11(B), the back surface 101B on the end 101D side of the patch 101 detaches from the adhesive surface 102B of the double-sided tape 102, leaving only the double-sided tape 102 on the medication attachment surface 10 of the device 1. Thus, when the patch 101 is attached to the medication attachment surface 10 of the device 1 via the double-sided tape 102, the back surface 101B of the patch 101 detaches from the double-sided tape 102 when the protective cover 101C is peeled off from the medication surface 101A of the patch 101. As a result, it is clear that when using double-sided tape 102, the adhesive strength of the adhesive surface 102B of the double-sided tape 102 needs to be increased. However, if the adhesive strength is increased, it will be higher than the adhesive strength between the affected area and the patch 101, resulting in the problem that the adhesive surface 102B of the double-sided tape 102 cannot be peeled off the patch 101 after it has been applied to the affected area.

[0034] In this way, the adhesive patch 101 can be attached to the medication attachment surface 10 using the adhesive patch attachment tape 11 of this embodiment, and the user can then wear the device 1 to apply the adhesive patch 101 to the affected area on their back. Subsequently, when the user removes the device 1, the adhesive patch attachment tape 11 detaches from the back surface 101B of the adhesive patch 101, and the adhesive patch attachment tape 11 is collected back on the medication attachment surface 10 side, leaving only the adhesive patch 101 on the affected area on the back. The adhesive patch attachment tape 11 of this embodiment can reduce the adhesive strength on the side corresponding to the adhesive surface 102B of the double-sided tape 102 compared to when using the double-sided tape 102 described above, and can be used with various adhesive patches 101 that have different adhesive strengths between the affected area and the adhesive patch 101.

[0035] Next, we will explain, with reference to Figures 16 to 18, the case in which the user removes the wearable device 1 after the adhesive patch 101 has been applied to the affected area on the back by wearing the wearable device 1 to which the adhesive patch 101 has been attached using adhesive patch attachment tape 11.

[0036] When the user puts on the device 1, the second adhesive surface 13 of the adhesive patch 11 is attached to the medication attachment surface 10 of the device 1, and the first adhesive surface 12 of the adhesive patch 11 is attached to the back surface 101B of the patch 101. In this state, when the user puts on the device 1, the medication surface 101A of the patch 101 can be attached to the affected area (skin) 103 on the back.

[0037] After the patch 101 is applied to the affected area 103 on the back, the user removes the device 1, causing the medication attachment surface 10 to move away from the affected area 103 (direction F4 indicated by arrow). At this time, the adhesion between the back surface 101B of the patch 101 and the first adhesive surface 12 of the patch attachment tape 11 is such that, as described above, when the protective cover 101C is peeled off, the patch 101 and the patch attachment tape 11 deform in unison, making it difficult for the back surface 101B of the patch 101 to peel off from the patch attachment tape 11, and only the protective cover 101C peels off. On the other hand, when the medication attachment surface 10 moves away from the affected area 103 (direction F4 indicated by arrow), even though the adhesive (adhesion strength) is the same, it becomes easier to peel off than when the protective cover 101C is peeled off. Furthermore, when the medication attachment surface 10 separates from the affected area 103, the adhesion between the second adhesive surface 13 of the adhesive patch 11 and the medication attachment surface 10, which is the adhesion between resin materials, is maintained.

[0038] At this time, as shown in Figure 18, the adhesive patch attachment tape 11 deforms into an open position like a hinge, centered on the folded portion 11D. As a result, the first adhesive surface 12 tilts relative to the back surface 101B of the adhesive patch 101 and peels off from the back surface 101B of the adhesive patch 101. In this case, the first adhesive surface 12 is converted from surface adhesive to linear adhesive with the part that is peeling off as the leading part due to the tilting, and since linear adhesive peels off with less force than surface adhesive, the first adhesive surface 12 peels off with less force than when it peels off as surface adhesive.

[0039] Furthermore, since the first adhesive surface 12 is composed of multiple triangular adhesive pieces 12A, when the medication attachment surface 10 separates from the affected area 103, these multiple adhesive pieces 12A peel off independently and sequentially from the back surface 101B of the patch 101. At this time, because the adhesive pieces 12A are divided into independent small areas with small adhesive forces, each adhesive piece 12A can be peeled off with less force than when the patch attachment tape 11 is peeled off as a whole. They peel off with small, consistent force, sequentially and independently, and as a result, the entire first adhesive surface 12 can be smoothly peeled off with less force than if it were not divided.

[0040] Here, if a large tensile force acts on the patch 101 just before the first adhesive surface 12 of the patch attachment tape 11 detaches from the patch 101, wrinkles are likely to form around the periphery of the patch 101. In contrast, the multiple adhesive pieces 12A that make up the first adhesive surface 12 are easily peeled off by hinge movement, and also have a triangular shape with the folded portion 11D side of the patch attachment tape 11 as the base and the area gradually decreasing as it moves away from the folded portion 11D. Therefore, just before the first adhesive surface 12 detaches from the patch 101, the tensile force acting on the patch 101 from the first adhesive surface 12 decreases, which suppresses the formation of wrinkles around the periphery of the patch 101, and allows the patch 101 to be neatly applied to the affected area 103.

[0041] Next, as a comparative example of the adhesive patch attachment tape 11 according to this embodiment, we will describe the case in which the user removes the wearable device 1 after the adhesive patch 101 has been attached to the affected area 103 on the back by wearing the wearable device 1 to which the adhesive patch 101 has been attached using double-sided tape 102, with reference to Figures 19 and 20.

[0042] When the user puts on the device 1, the adhesive side 102A of the double-sided tape 102 is attached to the drug attachment surface 10 of the device 1, and the adhesive side 102B of the double-sided tape 102 is attached to the back surface 101B of the patch 101. In this state, when the user puts on the device 1, the drug surface 101A of the patch 101 is attached to the affected area (skin) 103 on the back, as shown in Figure 19.

[0043] After the patch 101 is applied to the affected area 103 on the back, when the user removes the device 1, the medication attachment surface 10 moves away from the affected area 103 (direction indicated by arrow F4). In this case, the adhesive surface 102A of the double-sided tape 102 is in surface contact with the medication attachment surface 10 over its entire surface, and the adhesive surface 102B of the double-sided tape 102 is also in surface contact with the back surface 101B of the patch 101 over its entire surface. Therefore, the adhesive force between the adhesive surface 102A and the medication attachment surface 10, and the adhesive force between the adhesive surface 102B and the back surface 101B of the patch 101 are greater than the adhesive force between the medication surface 101A of the patch 101 and the affected area 103. As a result, it can be seen that when the device 1 is removed, the patch 101 is pulled away from the affected area 103 by the double-sided tape 102.

[0044] Furthermore, even if the adhesive surface 102B of the double-sided tape 102 can be peeled off the back surface 101B of the patch 101 while the medicated surface 101A of the patch 101 remains attached to the affected area 103, the adhesive force of the adhesive surface 102B to the patch 101 is so strong that the periphery of the patch 101 is stretched just before the adhesive surface 102B of the double-sided tape 102 detaches from the patch 101. This causes large wrinkles to form around the periphery of the patch 101, reducing the adhesive force between the medicated surface 101A of the patch 101 and the affected area 103, making it easier for the patch 101 to peel off from the affected area 103. As a result, it can be seen that when using double-sided tape 102, even if the device 1 is worn and the adhesive patch 101 is applied to the affected area 103, the adhesive patch 101 peels off from the affected area 103 when the device 1 is removed, making it difficult to properly apply the adhesive patch 101 to the affected area 103.

[0045] The adhesive patch attachment tape 11 according to this embodiment has the configuration described above. Next, the procedure for attaching the adhesive patch 101 to the user's back using the wearable device 1, and the function of the adhesive patch attachment tape 11 will be explained.

[0046] As shown in Figure 12, for example, if the user has two affected areas 103 on their back, these two affected areas 103 are in positions that are difficult for the user to reach, and the user cannot directly apply the adhesive patch 101 to the affected areas 103 with their own hands. Therefore, the user prepares the wearable device 1 according to this embodiment.

[0047] First, the user puts on the garment 1 by putting their left arm through the left cuff 7 and right cuff 8 of the garment 1, and with the collar 6 surrounding their neck, they bring the left shoulder portion 4 and right shoulder portion 5 of the garment 1 into contact with their left shoulder and right shoulder. As a result, the drug attachment surface 10 provided in the opening 9A of the back body 9 faces the affected area 103 on the back, and the affected area 103 can be seen through the drug attachment surface 10 from the back of the user.

[0048] In this state, as shown in Figure 13, the user grasps the L-shaped arm 105 with a marker (writing instrument, etc.) 104 attached to its tip and presses the marker 104 over the affected area 103. In this case, since the affected area 103 on the back is covered by the medication attachment surface 10, a mark (ink from the marker 104) 106 adheres to the outer surface 10B of the medication attachment surface 10 at a position corresponding to the affected area 103.

[0049] After marking the outer surface 10B of the medication attachment surface 10 with a mark 106 corresponding to the affected area 103, the user removes the device 1 and opens the left front panel 2 and the right front panel 3 of the device 1. This allows the mark 106 attached to the outer surface 10B of the medication attachment surface 10 to be visually inspected from the inner surface 10A side of the medication attachment surface 10. Next, as shown in Figure 14, the user attaches the patch 101 to two locations on the inner surface 10A of the medication attachment surface 10 that correspond to the mark 106, using the patch attachment tape 11.

[0050] For example, as shown in Figure 4, two adhesive patches 11 are placed at positions corresponding to the ends 101D on both sides in the longitudinal direction of the patch 101, and the second adhesive surfaces 13 of these adhesive patches 11 are adhered to the inner surfaces 10A of the medication attachment surface 10. Then, the first adhesive surfaces 12 of the two adhesive patches 11 are adhered to the back surface 101B of the patch 101. Alternatively, the first adhesive surfaces 12 of the adhesive patches 11 may be adhered to the back surface 101B of the patch 101 before the second adhesive surfaces 13 of the adhesive patches 11 are adhered to the medication attachment surface 10. Furthermore, as a preliminary step, a film-like material is prepared that is appropriately larger than the vertical and horizontal dimensions of the patch 101, and whose edges or back surface can be easily fixed to the inner surface 10A of the medication attachment surface 10 with cellophane tape or the like. By adhering the back surface 101B of the patch 101 to this film-like material via the patch attachment tape 11, the preparation process can be carried out more smoothly in a smaller space.

[0051] Next, as shown in Figure 6, the protective cover 101C is peeled off from the medicated surface 101A of the patch 101. In this case, the user grasps the end 101C1 of the protective cover 101C and pulls this end 101C1 in the direction of arrow F1 in Figure 7 and arrow F2 in Figure 8. As a result, the patch 101 is pulled by the protective cover 101C, and the elastic patch 101 is lifted at the end 101D side and deformed into a mountain shape.

[0052] At this time, the adhesive patch attachment tape 11 can be deformed into an open position like a hinge centered on the folded portion 11D (an open position where the non-adhesive surfaces 11C are separated from each other), thereby compensating for the gap between the end portion 101D and the medication attachment surface 10. As a result, the first adhesive surface 12 can follow the back surface 101B of the patch 101 due to its own adhesive force, and adhesion between the first adhesive surface 12 of the adhesive patch attachment tape 11 and the back surface 101B of the patch 101 can be maintained.

[0053] Furthermore, as the protective cover 101C peels off and the peel line reaches a position corresponding to the adhesive tape 11 on the back of the adhesive patch 101, as shown in Figure 10, the multiple adhesive pieces 12A that make up the first adhesive surface 12 of the adhesive tape 11 will embed the vertices of their respective triangles into the back surface 101B of the adhesive patch 101.

[0054] On the other hand, when the adhesive patch 101 is pulled by the protective cover 101C, it generates a force (restoring force) in the direction of contraction due to its own elasticity. This restoring force acts using the indented portion as a foothold, causing the adhesive patch attachment tape 11 to close in a direction like a hinge centered on the folded portion 11D (in a direction in which the non-adhesive surfaces 11C move closer to each other). As a result, the adhesion between the remaining protective cover 101C and the medicated surface 101A of the adhesive patch changes from surface adhesion to linear adhesion. In this case, since linear adhesion has weaker adhesive strength than surface adhesion, the two become easier to separate with less force, and combined with the tensile force f1, only the protective cover 101C peels off easily. In this way, as shown in Figure 9, the protective cover 101C can be easily peeled off the medicated surface 101A of the patch 101 while maintaining adhesion between the back surface 101B on the end 101D side of the patch 101 and the first adhesive surface 12 of the patch attachment tape 11.

[0055] In this way, after attaching (temporarily fixing) the patch 101 to the medication attachment surface 10 of the device 1 via the patch attachment tape 11, the user puts the device 1 back on, as shown in Figure 15. This allows the medication surface 101A of the patch 101 attached to the medication attachment surface 10 to be precisely facing the affected area 103 on the back. In this state, the user moves the device 1 forward, bringing the medication attachment surface 10 into contact with the back. This allows the medication surface 101A of the patch 101 attached to the medication attachment surface 10 to be precisely applied to the affected area 103 on the back (see Figure 16).

[0056] After attaching the medicated surface 101A of the patch 101, which is attached to the medicated surface 10, to the affected area 103, the user moves the medicated surface 10 away from the affected area 103 (in the direction of arrow F4 in Figure 18) and removes the device 1. At this time, as shown in Figure 18, the patch attachment tape 11 deforms into an open position like a hinge with the folded portion 11D as the center. This allows the first adhesive surface 12 to be peeled off the back surface 101B of the patch 101 while it is tilted relative to the back surface 101B of the patch 101.

[0057] At this time, the first adhesive surface 12 is converted from surface adhesive to linear adhesive, with the part that peels off being the leading edge. Since linear adhesive peels off with less force than surface adhesive, the first adhesive surface 12 is easier to peel off than when it peels off as surface adhesive. As a result, with the second adhesive surface 13 of the adhesive patch 11 still attached to the medication attachment surface 10, only the first adhesive surface 12 can be peeled off from the back surface 101B of the adhesive patch 101.

[0058] Furthermore, the first adhesive surface 12 of the adhesive patch attachment tape 11 is composed of multiple triangular adhesive pieces 12A. Therefore, when the medication attachment surface 10 separates from the affected area 103, these multiple adhesive pieces 12A peel off independently and sequentially from the back surface 101B of the adhesive patch 101. At this time, because the adhesive pieces 12A are divided into independent small areas with small adhesive forces, each adhesive piece 12A can be peeled off with less force than if the adhesive patch attachment tape 11 were to peel off as a whole. As a result, the entire first adhesive surface 12 can be smoothly peeled off with less force than if it were not divided. This prevents the adhesive patch 101 from being pulled off the affected area 103 by the adhesive patch attachment tape 11, and allows the adhesive patch 101 to remain attached to the affected area 103 even when the wearing device 1 is removed. Furthermore, the adhesive patch attachment tape 11 can be detached from the back surface 101B of the adhesive patch 101 and recovered to the medication attachment surface 10.

[0059] Here, if a large tensile force acts on the adhesive patch 101 just before the first adhesive surface 12 of the adhesive patch attachment tape 11 detaches from the adhesive patch 101, wrinkles are likely to form around the periphery of the adhesive patch 101. In contrast, the multiple adhesive pieces 12A constituting the first adhesive surface 12 have a triangular shape, with the folded portion 11D side of the adhesive patch attachment tape 11 as the base, and the area gradually decreasing as it moves away from the folded portion 11D. Therefore, just before the first adhesive surface 12 detaches from the adhesive patch 101, the tensile force acting on the adhesive patch 101 from the first adhesive surface 12 decreases, thus suppressing the formation of wrinkles around the periphery of the adhesive patch 101.

[0060] With the user having removed the device 1, the adhesive patch 101 is applied to the area on the user's back corresponding to the affected area 103, as shown in Figure 21. In this way, the user can apply the adhesive patch 101 to the affected area 103 on their back, which is difficult for them to reach, and the medication from the adhesive patch 101 can be supplied to the affected area 103 by themselves.

[0061] Thus, this embodiment provides an adhesive patch attachment tape 11 for attaching an adhesive patch 101 to a wearable device 1 for attaching the adhesive patch 101 to a wound 103, comprising a tape-shaped base material 11A and an adhesive surface 11B provided on one side of the base material 11A, wherein the base material 11A is folded back so that the other side of the base material 11A faces each other, thereby dividing the adhesive surface 11B into a first adhesive surface 12 that adheres to the adhesive patch 101 and a second adhesive surface 13 that adheres to the wearable device 1.

[0062] With this configuration, the adhesive patch attachment tape 11 is formed as a double-folded tape that is folded in half in the width direction with the folded portion 11D as the center, so that the first adhesive surface 12 and the second adhesive surface 13 can move relative to each other. For this reason, when the protective cover 101C is peeled off from the drug surface 101A of the adhesive patch 101 while the adhesive patch 101 is attached to the drug attachment surface 10 of the wearer 1 via the adhesive patch attachment tape 11, even if the adhesive patch 101 is pulled and deformed by the protective cover 101C, the adhesive patch attachment tape 11 also deforms in sync to an open hinge position, so that the first adhesive surface 12 adhered to the adhesive patch 101 can follow the deformed adhesive patch 101. In this way, the first adhesive surface 12 continues to adhere to the patch 101 while following the deformation of the patch 101, thereby ensuring adhesion between the first adhesive surface 12 and the patch 101 until the protective cover 101C peels off, and allowing the protective cover 101C to be peeled off while the patch 101 remains attached to the medication attachment surface 10.

[0063] Furthermore, after the medicated surface 101A of the patch 101 attached to the device 1 is adhered to the user's affected area 103, when the user removes the device 1, the device 1 separates from the affected area 103, widening the gap between the first adhesive surface 12 and the second adhesive surface 13, and the patch attachment tape 11 deforms into an open hinge position. As a result, the first adhesive surface 12 peels off the patch 101 at an angle, converting the first adhesive surface 12 from surface adhesion to linear adhesion, allowing it to be peeled off with less force than in the case of surface adhesion. Therefore, while the patch 101 remains attached to the affected area 103, the first adhesive surface 12 of the patch attachment tape 11 peels off from the back surface 101B of the patch 101, and only the patch attachment tape 11 can be collected on the device 1 side.

[0064] In this embodiment, the area of ​​the first adhesive surface 12 is set to be smaller on the side of the base material 11A away from the folded portion 11D than on the side of the folded portion 11D. With this configuration, the adhesive force of the first adhesive surface 12 decreases as it moves away from the folded portion 11D. Therefore, after the medicated surface 101A of the patch 101 attached to the wearable device 1 is adhered to the affected area 103, when the user removes the wearable device 1, the first adhesive surface 12 peels off from the folded portion 11D side and separates from the back surface 101B of the patch 101. This suppresses the tensile force acting on the patch 101 from the first adhesive surface 12, thereby preventing wrinkles from forming on the patch 101.

[0065] In this embodiment, the area of ​​the first adhesive surface 12 gradually decreases as it moves away from the folded portion 11D of the base material 11A. With this configuration, when the user removes the wearer 1 and the first adhesive surface 12 peels off from the folded portion 11D side, the tensile force acting on the patch 101 from the first adhesive surface 12 gradually decreases, thus preventing wrinkles from forming on the patch 101 when the first adhesive surface 12 detaches from the back surface 101B of the patch 101.

[0066] In this embodiment, the first adhesive surface 12 is composed of a plurality of adhesive pieces 12A whose area gradually decreases as they move away from the folded portion 11D of the base material 11A. With this configuration, after the drug surface 101A of the patch 101 attached to the wearable device 1 is adhered to the affected area 103, when the user removes the wearable device 1 and peels the first adhesive surface 12 from the back surface 101B of the patch 101, the plurality of adhesive pieces 12A peel off from the patch 101 independently and sequentially. As a result, the adhesive force between the first adhesive surface 12 of the patch attachment tape 11 and the back surface 101B of the patch 101 is reduced, and the patch attachment tape 11 can be smoothly peeled off from the patch 101. Moreover, the adhesive force of the first adhesive surface 12 to the patch 101 can be adjusted by changing the shape (area) of the adhesive pieces 12A.

[0067] In this embodiment, each of the multiple adhesive pieces 12A is triangular in shape. With this configuration, the vertices of the multiple adhesive pieces 12A are pointed, and when peeling the protective cover 101C from the drug surface 101A of the patch 101 attached to the wearer 1 via the patch attachment tape 11, the vertices of the multiple adhesive pieces 12A can bite into the back surface 101B of the patch 101.

[0068] On the other hand, when the adhesive patch 101 is pulled by the protective cover 101C, it generates a force (restoring force) in the direction of contraction due to its own elasticity. At this time, the adhesive patch 101 can peel off the protective cover 101C on its own by using the indented parts at the vertices of the multiple adhesive pieces 12A as a foothold to bring the non-adhesive surfaces 11C closer together (moving in the direction of closing the hinge). As a result, the protective cover 101C can be quickly peeled off the adhesive patch 101 while the adhesion between the adhesive patch 101 and the first adhesive surface 12 of the adhesive patch attachment tape 11 is maintained.

[0069] Thus, in this embodiment, by changing the angle of the adhesive patch attachment portion 11F with respect to the base portion 11E of the substrate 11A, the adhesion between the back surface 101B of the adhesive patch 101 and the first adhesive surface 12 of the adhesive patch attachment tape 11 is made possible without changing the adhesive strength of the adhesive of the adhesive patch attachment tape 11 during the process. This allows the protective cover 101C to be peeled off from the adhesive patch 101 while the adhesive patch 101 is attached to the medication attachment surface 10 of the wearer 1, and after the adhesive patch 101 is applied to the affected area 103, the adhesive patch attachment tape 11 can be peeled off from the adhesive patch 101, leaving only the adhesive patch 101 on the affected area 103 on the back.

[0070] In this embodiment, a vest-type wearable device 1 worn by the user is shown as an example of an auxiliary device. However, the present invention is not limited to this, and for example, a plate-shaped drug attachment plate that can be brought into contact with the user's back may be prepared, and the adhesive patch 101 may be attached to this drug attachment plate via an adhesive patch attachment tape 11.

[0071] Furthermore, in this embodiment, the first adhesive surface 12 of the adhesive patch attachment tape 11 is shown to be composed of multiple adhesive pieces 12A having the same triangular shape. However, this is not limited to this, and for example, the shapes of the multiple adhesive pieces 12A may be different, and they may be trapezoidal or rectangular instead of triangular. However, it is desirable to provide a gap between adjacent adhesive pieces 12A in order to facilitate deformation. Also, it is desirable for the adhesive pieces 12A to have pointed ends so that they can easily bite into the adhesive patch 101, but they do not necessarily have to be pointed ends.

[0072] Furthermore, the adhesive patch attachment material of the present invention allows the protective cover to be peeled off while the adhesive patch is still attached to the attachment, and after the user applies the adhesive patch to the affected area, the attachment material peels off from the adhesive patch. While this effect is achieved in most cases, it may not be achieved depending on the user's skin condition and the material on the back of the adhesive patch.

[0073] Furthermore, in the above-described embodiment, the adhesive on the first adhesive surface 12 and the second adhesive surface 13 was the same, but this is not limited to this, and different adhesives may be used. In this case, by using an adhesive with stronger adhesive strength on the second adhesive surface 13, it is possible to prevent the adhesive tape 11 from peeling off the drug attachment surface 10. Also, in the above-described embodiment, the first adhesive surface 12 and the second adhesive surface 13 were on the same surface, but they may be on different surfaces, that is, the second adhesive surface 13 may be provided on the drug attachment surface 10 side of the device 1, and the first adhesive surface 12 may be provided on the drug attachment surface 101 side. In this case, the adhesive tape 11 is used without folding it over.

[0074] Next, Figure 22 shows a second embodiment of the present invention. The adhesive patch attachment material 21 according to this embodiment has a base material 22 formed from a resin material having appropriate elasticity. The base material 22 comprises, for example, a single base portion 22A made of a rectangular flat plate, and a pair (2) adhesive patch attachment portions 22B formed on both sides of the base portion 22A in the longitudinal direction. The base portion 22A is, for example, a rectangle similar in shape to the adhesive patch 101 but slightly larger, and the adhesive patch attachment portions 22B extend in a sawtooth shape in a direction perpendicular to the longitudinal direction of the base portion 22A. The adhesive patch attachment portions 22B are formed by raising (bending) a plurality of upright pieces 23, separated from the base portion 22A by sawtooth-shaped cuts 22C, towards the surface side of the base portion 22A, starting from a hinge portion (folded portion) 24. The upright pieces 23 have a triangular shape with the side away from the hinge portion 24 being the pointed end. The adhesive patch attachment section 22B, which is composed of these multiple upright pieces 23, can be angled from the base section 22A, starting from the hinge section 24.

[0075] The surface of the patch attachment portion 22B on the side where the upright piece 23 is erected is a first adhesive surface 25 that adheres to the patch 101. The first adhesive surface 25 is formed by applying an adhesive to the surface of the patch attachment portion 22B or by attaching double-sided tape. Therefore, the multiple upright pieces 23 constituting the patch attachment portion 22B are adhesive pieces. On the other hand, the back surface of the base portion 22A on the side opposite to the side where the upright piece 23 is erected is a second adhesive surface 26 that adheres to the medication attachment surface 10 of the wearer 1. The entire surface or part of the second adhesive surface 26 (for example, the four corners of the base portion 22A) is coated with an adhesive or has double-sided tape attached.

[0076] The adhesive patch attachment material 21 according to the second embodiment has the configuration described above, and the same effects and advantages as the adhesive patch attachment tape 11 according to the first embodiment can be obtained with this adhesive patch attachment material 21 as well.

[0077] However, since the adhesive patch attachment material 21 has two adhesive patch attachment parts 22B formed on a single base part 22A, the two adhesive patch attachment parts 22B can be attached to the medication attachment surface 10 of the wearer 1 simply by adhering the base part 22A (second adhesive surface 26) to the medication attachment surface 10. Therefore, there is no need to attach the two adhesive patch attachment parts 22B to the medication attachment surface 10 individually, and the attachment of the adhesive patch attachment parts 22B can be easily performed.

[0078] In the second embodiment of the adhesive patch attachment material 21, the medication attachment surface 10 of the wearer 1 itself can be used as the base material 22. In this case, an adhesive patch attachment section 22B consisting of multiple sets of upright pieces 23 is formed on the medication attachment surface 10, and the upright piece 23 corresponding to the affected area 103 is selected, and the adhesive patch 101 is attached for use.
