Description

[Technical field]

[0001] The present invention relates to a tubular body fixing device for fixing a medical tubular body such as a tube for infusion and drainage of fluids, a catheter, etc., to the skin or the like of a patient. [Background technology]

[0002] Conventionally, a tubular body fixing device for attaching and fixing a tube or catheter for infusion or drainage to the skin of a patient is known (Patent Document 1). For example, as shown in Fig. 9, a tubular body fixing device 101 includes a lower layer 102 to be attached to the skin of a patient, a tubular body engaging part 104 disposed on the lower layer 102, and an upper layer 103 connected to the lower layer 102. The tubular body T is sandwiched between the adhesive surface of the tubular body engaging part 104 and the adhesive surface of the upper layer 103, and is fixed between the lower layer 102 and the upper layer 103 by adhesion between these adhesive surfaces. In this tubular body fixing device 1, the adhesive surfaces are not easily released from the adhesion in the vicinity of the tubular body T, so that the upper layer 103 is not easily peeled off from the lower layer 102.

[0003] [Patent Document 1] JP 2020-151236 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, when the tubular body fixing device 101 becomes dirty, for example, there are cases where it is desired to replace only the tubular body fixing device 101 with a new one while continuing to use the tubular body T as is. However, with the tubular body fixing device 101, the tubular body T is firmly fixed to the tubular body fixing device 101 by adhesion between the adhesive surfaces, and so there is a risk that the tubular body T may be difficult to separate from the tubular body fixing device 101.

[0005] An object of the present invention is to provide a tubular body fastener that allows the tubular body to be easily separated when replacing the tubular body fastener. [Means for solving the problem]

[0006] The tubular body fixing device of the present invention is a tubular body fixing device capable of fixing a tubular body on the skin, and comprises: a tubular body engaging part which is a sheet-like part located on the inside when in use and has a tubular body adhesive layer on its outer surface when in use that holds the tubular body; and an outer layer part which is a sheet-like part located on the outside when in use and can cover from the outside the tubular body engaging part and the tubular body held by the tubular body adhesive layer and has a polymerization adhesive layer on its inner surface when in use, and the tubular body engaging part is in contact with the tubular body when in use. The tubular body has a non-adhesive portion where the adhesive layer for the tubular body is not formed, at least at one end in the longitudinal direction of the tubular body, at a position where they overlap in the inward and outward directions, and the outer layer portion has a notch or cut that penetrates in the inward and outward direction at a portion that overlaps in the inward and outward directions with the non-adhesive portion when in use, and the position at which the non-adhesive portion is formed in the tubular body engaging portion is a position close to the edge of the tubular body engaging portion on the first separation side that separates from the tubular body engaging portion first when the outer layer portion is peeled off from the tubular body engaging portion in the width direction perpendicular to the longitudinal direction.

[0007] According to this configuration, since the non-adhesive portion is formed biased toward the leading-separation side in the width direction in the tubular body engaging portion, the width dimension of the tubular body adhesive layer located between the edge of the leading-separation side and the tubular body can be reduced. Since the adhesive strength is reduced by the reduced width dimension, the outer layer portion can be easily peeled off from the tubular body engaging portion.

[0008] Moreover, in the tubular body fixing device, the non-adhesive portion is a notch that penetrates the tubular body engaging portion in an inward / outward direction, and the outer layer portion has a notch that penetrates in an inward / outward direction in a portion that overlaps in an inward / outward direction with the non-adhesive portion during use.

[0009] According to this configuration, the shape of the notch in the tubular body locking portion matches the shape of the notch in the outer layer portion, thereby improving the aesthetic appearance of the tubular body fastener.

[0010] In the tubular body fixture, the edge on the leading separation side of the tubular body engaging portion is provided on the leading separation side relative to the center in the width direction of the non-adhesive portion.

[0011] According to this configuration, the adhesive layer for the tubular body can be brought into contact with the tubular body located approximately in line with the center of the non-adhesive portion in the width direction, so that the tubular body can be securely held by the tubular body engaging portion.

[0012] The tubular body fixing device further comprises an inner layer portion which is a sheet-like portion facing the outer layer portion so as to sandwich the tubular body engaging portion therebetween, the inner surface of the inner layer portion having a skin adhesive layer which adheres to the skin when in use, one end of the inner layer portion in the width direction being integrated with the outer layer portion before use, and the other end of the inner layer portion in the width direction being the first-to-detach side.

[0013] According to this configuration, the tubular body fixing device can be made into a single unit, which makes it easy to use. Also, the outer layer portion can be peeled off from the tubular body engaging portion in a fixed direction.

[0014] In the tubular body fixing device, the inner layer portion has a notch or cut corresponding to the outer layer portion in a portion that overlaps the outer layer portion in the inward / outward direction during use.

[0015] According to this configuration, by providing a notch or cut in the inner layer portion that adheres to the skin, the edge length of the inner layer portion can be increased, and accordingly the inner layer portion can be more firmly attached to the skin. Effect of the Invention

[0016] As described above, according to the present invention, a tubular body fastener that allows the tubular body to be easily separated when replacing the tubular body fastener can be provided. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, an embodiment of the present invention will be described with reference to Fig. 1 to Fig. 8. The tubular body fixing device is a tubular body fixing device capable of fixing a tubular body T onto the skin, and is, for example, a device capable of fixing a medical tubular body such as a tube for infusion and drainage, a catheter, etc. onto the skin of a patient. In this specification, in the inside-outside direction, the side closer to the skin is referred to as the inside, and the side farther from the skin is referred to as the outside.

[0019] 1 and 2(a), the tubular body fixing device 1 comprises a tubular body locking portion 4 which is a sheet-like portion located on the inside when in use, and an outer layer portion 3 which is a sheet-like portion located on the outside when in use. The tubular body fixing device 1 of this embodiment comprises an inner layer portion 2 which is a sheet-like portion facing the outer layer portion 3 so as to sandwich the tubular body locking portion 4 inside. The tubular body fixing device 1 also comprises a patch portion 8 which is located on the outside of the outer layer portion 3 when in use.

[0020] This tubular body fastener 1 comprises an inner layer release liner 5 arranged inside the inner layer portion 2, an outer layer release liner 6 arranged inside the outer layer portion 3, and an anchoring portion release liner 7 arranged outside the tubular body anchoring portion 4. Furthermore, the tubular body fastener 1 comprises a patch portion release liner 9 arranged inside the patch portion 8. Each of the release liners 5, 6, 7, 9 is in the form of a sheet, and is removed when used.

[0021] In this tubular body fixing device 1, the inner layer portion 2 and the outer layer portion 3 extend in one direction (the left-right direction in Fig. 1 and Fig. 2(a), hereinafter referred to as the horizontal direction). Note that, although the outer layer portion 3 extends obliquely in Fig. 2(a) and Fig. 2(b), in reality it extends approximately parallel to the inner layer portion 2.

[0022] The tubular body fixing device 1 has an external appearance, for example, of a substantially square sheet shape when viewed in a plan view from a direction substantially perpendicular to the outer layer portion 3 (see FIG. 1). The horizontal dimension of the tubular body fixing device 1 of this embodiment and the dimension of the tubular body fixing device 1 in a depth direction perpendicular to the horizontal direction are both about 50 mm to 100 mm, for example 85 mm.

[0023] The tubular body locking portion 4 is a member capable of locking the tubular body T in a sandwiched state between the inner layer portion 2 and the outer layer portion 3 (see FIG. 2(b)). The tubular body locking portion 4 also has an adhesive layer 40 for tubular bodies that holds the tubular body T on its outer surface when in use. The tubular body locking portion 4 also has a non-adhesive portion 41 where the adhesive layer 40 for tubular bodies is not formed, at least at one end in the longitudinal direction of the tubular body T (hereinafter simply referred to as the "longitudinal direction"), at a position that overlaps with the tubular body T in the inward / outward direction (the up-down direction in FIG. 2(b)) when in use (see FIGS. 3 and 6(b)).

[0024] 2(b), the tubular body locking part 4 of this embodiment is sheet-shaped, and specifically extends in the longitudinal direction and in a width direction perpendicular to the longitudinal direction (hereinafter simply referred to as the width direction) on the inner layer part 2. Moreover, the dimension in the width direction of the tubular body locking part 4 of this embodiment is preferably larger than the outer diameter of the tubular body T to be fixed to the tubular body fixture 1.

[0025] In this embodiment, the tubular body locking portion 4 is formed only by the adhesive layer 40 for the tubular body (so-called base layer-less), but the tubular body locking portion 4 may also be a double-sided tape in which an adhesive layer different from the adhesive layer 40 for the tubular body is provided on the inside of the base layer and the adhesive layer 40 for the tubular body is provided on the outside of the base layer.

[0026] The pressure-sensitive adhesive layer 40 for the tubular body is formed, for example, on the inner layer portion 2 (specifically, the base layer 21 of the inner layer portion 2 described later). As shown in Fig. 3, the pressure-sensitive adhesive layer 40 for the tubular body has one edge 42 which is the edge of the leading separation side (described later) of the tubular body engaging portion 4, and the other edge 43 which is the edge opposite to the leading separation side of the tubular body engaging portion 4. Both the one edge 42 and the other edge 43 are linear. Moreover, the one edge 42 and the other edge 43 extend along the longitudinal direction.

[0027] In the tubular body fastener 1 of the present embodiment, the non-adhesive portion 41 is a notch 410 formed in the tubular body adhesive layer 40 together with the base material layer 21 of the inner layer portion 2. In this tubular body fastener 1, one end edge 42 hangs over the notch 410, so that the length of the one end edge 42 in the longitudinal direction is shorter than the length of the other end edge 43 in the longitudinal direction.

[0028] For example, a pair (two) of notches 410 are arranged on both sides in the longitudinal direction. In this tubular body fastener 1, each notch 410 has the same shape, and each notch 410 has a symmetrical shape in the longitudinal direction. Note that one notch 410 may be arranged on one side in the longitudinal direction.

[0029] The non-adhesive portion 41 does not have to be the notch 410, and may simply be a portion where no adhesive is provided (for example, a portion where the surface of the base material layer 21 of the inner layer portion 2 is exposed).

[0030] The outer layer portion 3 can cover from the outside the tubular body locking portion 4 and the tubular body T held by the tubular body adhesive layer 40 (see FIG. 2(b)). For example, the base material layer 33 of the outer layer portion 3 is a sheet that covers the inner layer portion 2, the tubular body T, and the tubular body locking portion 4, and is, for example, a mesh sheet to improve breathability. The outer layer portion 3 of this embodiment is an adhesive bandage, for example, an adhesive bandage with a base material layer of a nonwoven fabric such as Kino White (registered trademark of Nitto Denko Corporation, the same applies below).

[0031] The outer layer portion 3 has a polymerization pressure-sensitive adhesive layer 31 on an inner surface 30 during use. Specifically, the outer layer portion 3 has a base layer 33 and the polymerization pressure-sensitive adhesive layer 31 disposed inside the base layer 33.

[0032] The outer layer portion 3 has a polymerization adhesive layer 31 at least in a region of the inner surface 30 that is located above the tubular body engaging portion 4 when attached to the tubular body engaging portion 4. In the tubular body fixing device 1 of this embodiment, the polymerization adhesive layer 31 is continuous over the entire horizontal area of ​​the outer layer portion 3, so that the entire inner surface 30 of the outer layer portion 3 is an adhesive surface. Note that the polymerization adhesive layer 31 does not need to contain a glue that can be attached to the skin, but it preferably contains an odorless glue in consideration of the comfort of the patient when using it.

[0033] The outer layer portion 3 has a notch 32 penetrating in the inward-outward direction at a portion that overlaps in the inward-outward direction with the non-adhesive portion 41 during use (see FIG. 1). Note that the outer layer portion 3 may have a cut (slit) penetrating in the inward-outward direction at a portion that overlaps in the inward-outward direction with the non-adhesive portion 41 during use instead of the cut 32. This cut 32 or cut extends, for example, along the longitudinal direction of the tubular body T.

[0034] In the tubular body fixture 1 of this embodiment, a pair (two) of notches 32 are provided on both sides in the longitudinal direction. Also, each notch 32 has a symmetrical shape in the longitudinal direction. Note that one notch 32 may be provided on one side in the longitudinal direction.

[0035] The cutout 32 has, for example, an elongated shape, specifically, a substantially semi-elliptical shape, but may have other shapes, such as a rectangular shape or a triangular shape.

[0036] Furthermore, the notch 32 has an asymmetric shape in the width direction perpendicular to the longitudinal direction of the tubular body T. Specifically, in the notch 32, the inclination of the first side 321 with respect to the width direction is gentler than the inclination of the second side 322 with respect to the width direction. In the tubular body fixing device 1 of the present embodiment, when the outer layer portion 3 overlaps the inner layer portion 2, the first side 321 with a gentle inclination with respect to the width direction is disposed on the side closer to a joining portion between the outer layer portion 3 and the inner layer portion 2, which will be described later, in the width direction.

[0037] In this tubular body fastener 1, the non-adhesive portion 41 in the tubular body locking portion 4 is formed at a position close to one end edge (edge ​​on the first separation side) 42 of the tubular body locking portion 4, which separates first from the tubular body locking portion 4 when the outer layer portion 3 is peeled off from the tubular body locking portion 4 in the width direction perpendicular to the longitudinal direction of the tubular body T (see FIG. 3). Specifically, the center C4 in the width direction of the non-adhesive portion 41 (for example, a center line passing through the tip edges of the notches 410 and extending in the longitudinal direction; in this embodiment, a center line connecting the tip edges of a pair of notches 410) is closer to one end edge 42 of the tubular body locking portion 4 than to the other end edge (edge ​​opposite to the first separation side) 43 of the tubular body locking portion 4.

[0038] In this way, in the tubular body locking portion 4, the non-adhesive portion 41 is formed biased toward the leading-separation side in the width direction, so that it is possible to reduce the width dimension of the tubular body adhesive layer 40 located between the edge 42 on the leading-separation side and the tubular body T arranged in agreement with the center C4. Also, since the area of ​​the tubular body adhesive layer 40 is reduced by the amount of the reduction in the width dimension in the tubular body locking portion 4, and the adhesive strength is reduced, it is easy to peel off the outer layer portion 3 from the tubular body locking portion 4 when replacing the tubular body fastener 1, etc.

[0039] In the tubular body fastener 1 of this embodiment, the non-adhesive portion 41 of the tubular body fastening portion 4 is a notch 410 that penetrates the tubular body fastening portion 4 in the inward and outward directions. The shape of the notch 410 of the tubular body fastening portion 4 matches the shape of the notch 32 of the outer layer portion 3. This improves the aesthetic appearance of the tubular body fastener 1.

[0040] Furthermore, in the tubular body fixture 1 of this embodiment, the edge 42 on the leading separation side of the tubular body locking portion 4 is provided on the leading separation side of the center C4 in the width direction of the non-adhesive portion 41. This allows the tubular body adhesive layer 40 to come into contact with the tubular body T located approximately coinciding with the center C4 in the width direction of the non-adhesive portion 41, so that the tubular body T can be reliably held by the tubular body locking portion 4.

[0041] The patch part 8 is a sheet that is placed further outside the outer layer part 3 during use (see FIG. 1). By attaching the patch part 8 to the outside of the outer layer part 3 and thickening the sheet that covers the tubular body engaging part 4, the outer layer part 3 can be reinforced.

[0042] For example, the patch part 8 is a mesh sheet to improve breathability. The patch part 8 of this embodiment is an adhesive bandage made of the same material as the outer layer part 3, for example, an adhesive bandage with a base layer of nonwoven fabric such as Kino White (registered trademark of Nitto Denko Corporation, the same applies below).

[0043] The patch part 8 has an adhesive layer 81 on an inner surface 80 during use (see FIG. 2(a)). For example, the patch part has a base layer 82 and the adhesive layer 81 disposed on the inner side of the base layer 82.

[0044] In the tubular body fastener 1 of this embodiment, a pair (two) of patch portions 8 are provided. The pair of patch portions 8 are lined up in the longitudinal direction. The pair of patch portions 8 are integrated, and a cut line L1 such as a perforation is provided at the boundary between them. Note that one patch portion 8 may be provided, or three or more patch portions 8 may be provided.

[0045] In addition, in this tubular body fixing device 1, the outer layer portion 3 and the patch portion 8 are integrated before use (see FIG. 1). Specifically, the outer layer portion 3 and the patch portion 8 are continuous with a cut line L2 such as a perforation provided at the boundary between them.

[0046] Furthermore, the outer layer portion 3 has a peeling end 34 (in this embodiment, a triangular peeling end 34) on the cut line L2. The peeling end 34 may have a shape other than a triangle, for example, a semicircular shape. The peeling end 34 has a shape that protrudes from the patch portion 8 toward the outer layer portion 3, but may have a shape that is embedded in the patch portion 8. The peeling end 34 of the patch portion 8 serves as a trigger for starting to peel off the patch portion 8 when replacing the tubular body fixing device 1 after use.

[0047] The inner layer part 2 is a sheet that can be attached to the skin (see FIG. 2(a)). The inner layer part 2 also has a skin adhesive layer 20 on its inner surface that adheres to the skin when in use. The inner layer part 2 in this embodiment is an adhesive bandage, for example an adhesive bandage having a base layer made of a nonwoven fabric such as kino white, the same as the outer layer part 3. In addition to the skin adhesive layer 20, the inner layer part 2 has a base layer 21 that is placed on the outside of the skin adhesive layer 20.

[0048] In the inner layer part 2 of this embodiment, no adhesive layer is formed on the outside of the base material layer 21. That is, the inner layer part 2 has an adhesive surface on one side (inner surface). The skin adhesive layer 20 contains a glue that can be attached to the skin and is unlikely to cause rashes, and preferably contains an odorless glue in consideration of comfort when used by a patient.

[0049] Moreover, one end 22 of the inner layer portion 2 in the width direction (left-right direction in FIG. 2(a)) perpendicular to the longitudinal direction of the tubular body T is integrated with the outer layer portion 3 before use. In the tubular body fixing device 1 of this embodiment, to simplify manufacture, the inner layer portion 2 is formed separately from the outer layer portion 3, and one end 22 of the inner layer portion 2 is attached to the outer layer portion 3 to be integrated with the outer layer portion 3 before use. Specifically, a portion constituting one end 35 of the polymerization pressure-sensitive adhesive layer 31 of the outer layer portion 3 is attached to the outer surface 23 of the inner layer portion 2, whereby the outer layer portion 3 is connected to the inner layer portion 2.

[0050] Furthermore, the other end 24 in the width direction of the inner layer portion 2 becomes the leading separation side. This allows the tubular body fixing device 1 to be configured as a single unit; specifically, since the tubular body fixing device 1 before use is in the form of a single united sheet, the tubular body fixing device 1 is easy to use and is also easy to manage before use. Also, the outer layer portion 3 can be peeled off from the tubular body engaging portion 4 in a fixed direction.

[0051] In the tubular body fixing device 1 of this embodiment, the outer layer portion 3 is separated from the outer surface 23 of the inner layer portion 2 in a region excluding one end portion 35 in the horizontal direction before the tubular body T is fixed. In addition, an outer layer release liner 6 is disposed in the region excluding one end portion 35 in the horizontal direction of the outer layer portion 3 before the tubular body T is fixed.

[0052] The inner layer portion 2 and the outer layer portion 3 may be formed integrally, for example, by folding a sheet of adhesive bandage (e.g., kino white) with the tubular body adhesive layer 40 disposed on the inside, the inner layer portion 2 and the outer layer portion 3 may be integrated before use. In this case, the tubular body fixing device 1 may be attached to the skin by providing an adhesive layer different from the tubular body adhesive layer 40 on the outer surface 23 of the inner layer portion 2.

[0053] Furthermore, the inner layer portion 2 has a notch 25 corresponding to the outer layer portion 3 in a portion that overlaps with the outer layer portion 3 in the inward-outward direction during use (see FIG. 3). Note that the inner layer portion 2 may have a cut (slit) corresponding to the outer layer portion 3 in a portion that overlaps with the outer layer portion 3 in the inward-outward direction during use, instead of the cut 25. By providing the cut 25 or cut in the inner layer portion 2 that adheres to the skin in this way, the edge length of the inner layer portion 2 can be increased, and the inner layer portion 2 can be attached to the skin more firmly.

[0054] The inner layer release liner 5, the outer layer release liner 6 and the locking portion release liner 7 are respectively protective materials for the adhesive surface of the skin adhesive layer 20 of the inner layer 2, the adhesive surface of the polymerization adhesive layer 31 of the outer layer 3, the adhesive surface of the tubular body adhesive layer 40 of the tubular body locking portion 4 and the adhesive layer 81 of the patch portion 8, and are, for example, release papers (see Figure 2(a)).

[0055] The inner layer release liner 5 has a slit 50 extending in the longitudinal direction (see FIG. 1). Therefore, the inner layer release liner 5 can be easily peeled off from the inner layer 2. In addition, by partially peeling off the inner layer release liner 5, the inner layer 2 can be partially attached to the skin, and then the remaining inner layer release liner 5 can be peeled off to attach the entire inner layer 2 to the skin, that is, the inner layer 2 can be temporarily fixed. The slit 50 is disposed, for example, at a portion that overlaps in the inner and outer directions with respect to the center in the horizontal direction of the inner layer 2. In the tubular body fixing device 1 of this embodiment, the inner layer release liner 5 includes a first region 51 and a second region 52 separated by the slit 50.

[0056] In this inner layer release liner 5, a different number of notches 500 (e.g., triangular notches) are formed in the outer periphery of the first region 51 and in the outer periphery of the second region 52. The number of notches 500 formed in each outer periphery indicates the order in which the regions 51, 52 are peeled off. In this embodiment, the regions 51, 52 are peeled off in order of the number of notches 500. A configuration in which such notches 500 are formed in each region 51, 52 is advantageous because the order in which the regions 51, 52 are peeled off can be grasped by touch and is easy to understand.

[0057] The shape of the notch 500 may be different, such as a shallower notch than the notch 500 in the tubular body fastener 1 of this embodiment. Also, in the inner layer release liner 5, a mark other than the notch 500, such as a slit or unevenness, may be provided to indicate the order in which the regions 51, 52 are to be peeled off. Also, each of the regions 51, 52 may be printed with a mark indicating the order in which the regions 51, 52 are to be peeled off.

[0058] In the tubular body fixing device 1 of this embodiment, the inner layer release liner 5 extends outward beyond the inner layer portion 2 when viewed in a plan view from a direction approximately perpendicular to the outer layer portion 3. That is, the area of ​​the inner layer release liner 5 is greater than the area of ​​the inner layer portion 2, and the outer peripheral edge of the inner layer portion release liner 5 is located outward beyond the outer peripheral edge of the inner layer portion 2. This makes it easy to peel the inner layer release liner 5 from the inner layer portion 2. Note that the inner layer release liner 5 has the same area as the inner layer portion 2, and the outer peripheral edge of the inner layer portion release liner 5 may overlap the outer peripheral edge of the inner layer portion 2.

[0059] The outer layer release liner 6 has a slit 60. This makes it easy to peel the outer layer release liner 6 from the outer layer portion 3. The slit 60 is disposed, for example, at a position overlapping with the slit 50 of the inner layer release liner 5 in the inner-outer direction. In the tubular body fixing device 1 of this embodiment, the outer layer release liner 6 includes a first region 61 and a second region 62 separated by the slit 60.

[0060] Furthermore, the locking portion release liner 7 is provided with a notch 70 (see FIG. 3). This notch 70 has the same shape as the notch 410 of the tubular body locking portion 4.

[0061] For example, a pair (two) of notches 70 are provided on both sides in the longitudinal direction. Each notch 70 has a symmetrical shape in the longitudinal direction. Alternatively, one notch 70 may be provided on one side in the longitudinal direction.

[0062] The cutout 70 has, for example, an elongated shape, specifically, a substantially semi-elliptical shape, but may have other shapes, such as a rectangular shape or a triangular shape.

[0063] Furthermore, the notch 70 has an asymmetric shape in the width direction perpendicular to the longitudinal direction of the tubular body T. Specifically, in the notch 70, the inclination of the first side 71 with respect to the width direction is gentler than the inclination of the second side 72 with respect to the width direction. In the tubular body fixing device 1 of the present embodiment, when the outer layer portion 3 overlaps the inner layer portion 2, the first side 71 with a gentle inclination with respect to the width direction is disposed on the side closer to the connection portion between the outer layer portion 3 and the inner layer portion 2 in the width direction.

[0064] The lengthwise dimensions of both widthwise edges 73, 74 of the locking portion release liner 7 are substantially the same. Both widthwise edges 73, 74 are straight. Both widthwise edges 73, 74 extend along the lengthwise direction.

[0065] In the tubular body fastener 1 of this embodiment, the locking portion release liner 7 extends outward beyond the tubular body locking portion 4 when viewed in a plan view from a direction substantially perpendicular to the outer layer portion 3. That is, the area of ​​the locking portion release liner 7 is larger than the area of ​​the tubular body locking portion 4, and the outer circumferential edge of the locking portion release liner 7 is located outward beyond the outer circumferential edge of the tubular body locking portion 4. This makes it easy to peel the locking portion release liner 7 from the tubular body locking portion 4. Note that the locking portion release liner 7 has the same area as the tubular body locking portion 4, and the outer circumferential edge of the locking portion release liner 7 may overlap the outer circumferential edge of the tubular body locking portion 4.

[0066] In the above tubular body fastener 1, the notch 410 of the tubular body locking portion 4 is sized so that the tubular body fastener 1 can adequately fasten the tubular body T. Below, a plurality of samples of the tubular body fastener 1 having different longitudinal dimensions of the notch 410 of the tubular body locking portion 4 were prepared, and a test was performed to measure the fastening force for the tubular body T (specifically, the force applied when the tubular body T was pulled).

[0067] In the tubular body fixing device 1, the longitudinal and widthwise dimensions of the inner layer portion 2 are both 75 mm. In addition, the widthwise dimensions of the notches 410 are both 10 mm. In this tubular body fixing device 1, notches 410 were provided on both sides in the longitudinal direction, and samples were prepared in which the longitudinal dimensions of the notches 410 were varied to 0 mm, 5 mm, 10 mm, 15 mm, 20 mm, 23 mm, and 25 mm.

[0068] The test is performed by attaching a sample (tubular body fixture 1) to an adherend (Bakelite plate), fixing a tubular body T (outer diameter 3.3 mm or outer diameter 6.3 mm) to the tubular body fixture 1, and pulling it at 1000 mm / min in a tensile direction of 90° using a tensile tester TENSILON (ORIENTEC RTC-1210A) (a method of reading the maximum value). Specifically, the method of reading the maximum value is a method of reading the numerical value when the tubular body T comes off due to peeling or lifting of the tubular body fixture 1. When attaching the tubular body fixture 1, the tubular body fixture 1 is made to blend with the adherend and the entire tubular body T, just as in actual use.

[0069] As a result of the test, when the outer diameter of the tubular body T was 3.3 mm, the fixing force was 15 N, 27 N, 29 N, 28 N, 28 N, 25 N, and 22 N when the longitudinal dimensions of the cutout 410 were 0 mm, 5 mm, 10 mm, 15 mm, 20 mm, 23 mm, and 25 mm, respectively. Also, when the outer diameter of the tubular body T was 6.3 mm, the fixing force was 20 N, 24 N, 31 N, 31 N, 33 N, 29 N, and 28 N when the longitudinal dimensions of the cutout 410 were 0 mm, 5 mm, 10 mm, 15 mm, 20 mm, 23 mm, and 25 mm, respectively.

[0070] As a result, it is preferable that the tubular body fixing tool 1 can fix the tubular body T with a fixing force of 22 N or more, and therefore, when the notches 410 are formed on both sides in the longitudinal direction of the tubular body fixing tool 1, the longitudinal dimension of the notches 410 is preferably 5 mm or more and 25 mm or less, in other words, it is preferable that the longitudinal dimension of the notches 410 is 5% or more and 35% or less of the longitudinal dimension of the inner layer portion 2. Furthermore, it is even more preferable that the tubular body fixing tool 1 can fix the tubular body T with a fixing force of 25 N or more, and therefore, when the notches 410 are formed on both sides in the longitudinal direction of the tubular body fixing tool 1, the longitudinal dimension of the notches 410 is even more preferably 10 mm or more and 23 mm or less, in other words, it is even more preferable that the longitudinal dimension of the inner layer portion 2 is 10% or more and 31% or less of the longitudinal dimension of the inner layer portion 2.

[0071] In addition, when the notch 410 is formed on one side in the longitudinal direction of the tubular body fixing device 1, the longitudinal dimension of the notch 410 may be longer than the longitudinal dimension of the notch 410 when the notch 410 is formed on both sides in the longitudinal direction of the tubular body fixing device 1.

[0072] Furthermore, the dimension of the portion of the tubular body engaging portion 4 adjacent to the notch 410 in the longitudinal direction is preferably 10% or more and 75% or less of the longitudinal dimension of the inner layer portion 2, and more specifically, it is desirable for it to be 25% or more and 70% or less.

[0073] Below, we will specifically explain how to use the tubular body fixing tool 1. First, we will explain how to fix the tubular body T with the tubular body fixing tool 1, and then we will explain how to remove the tubular body T from the tubular body fixing tool 1.

[0074] When fixing a tubular body T with the tubular body fixing tool 1, first, the first region 51 of the inner layer release liner 5 is peeled off and removed from the inner layer portion 2 of the tubular body fixing tool 1. Then, as shown in Fig. 4(a), a part of the inner layer portion 2 (specifically, a region including one end portion 22 in the horizontal direction of the inner layer portion 2) is applied onto the skin while the second region 52 of the inner layer release liner 5 remains attached. Thereafter, the second region 52 of the inner layer release liner 5 is peeled off and removed, and the remaining part of the inner layer portion 2 (specifically, a region including the other end portion 24 in the horizontal direction of the inner layer portion 2) is applied onto the skin as shown in Fig. 4(b).

[0075] Next, as shown in Fig. 4(c), the outer layer portion 3 is opened to expose the outer surface 23 of the inner layer portion 2, and the locking portion release liner 7 is peeled off and removed from the tubular body locking portion 4 as shown in Fig. 4(d). At this time, in the tubular body fixing device 1 of this embodiment, the first side 71, which has a gentle slope with respect to the peeling direction, is located on the side closer to the connecting portion between the outer layer portion 3 and the inner layer portion 2, so that when the locking portion release liner 7 is peeled off from the side farther from this connecting portion, it is easy to peel off the locking portion release liner 7 from the tubular body locking portion 4.

[0076] 5(a), the tubular body T is placed on the adhesive layer 40 for tubular body of the tubular body locking portion 4. At this time, the tubular body T is fixed to the inner layer portion 2 by the adhesive force of the adhesive layer 40 for tubular body of the tubular body locking portion 4. This allows the tubular body T to be temporarily fixed to the inner layer portion 2. In this tubular body fixing device 1, the tubular body T is placed at the position of the notch 410.

[0077] 5(b), the first region 61 of the outer layer release liner 6 is peeled off and removed from the outer layer portion 3, and then the second region 62 of the outer layer release liner 6 is peeled off and removed from the outer layer portion 3, as shown in Fig. 5(c). At this time, in the tubular body fixing device 1 of this embodiment, the first side 321, which has a gentle slope with respect to the peeling direction, is located on the side closer to the joining portion between the outer layer portion 3 and the inner layer portion 2, so that it is easy to peel the outer layer release liner 6 from the outer layer portion 3.

[0078] Furthermore, in this tubular body fixing device 1, the first region 61 and the second region 62 of the outer layer release liner 6 are peeled off from the outer layer portion 3, and then the patch portion 8 is separated from the outer layer portion 3. Note that the patch portion 8 may be separated from the outer layer portion 3 before the first region 61 and the second region 62 of the outer layer release liner 6 are peeled off from the outer layer portion 3. For example, immediately after the tubular body T is temporarily fixed to the inner layer portion 2, the patch portion 8 may be separated from the outer layer portion 3, and then the first region 61 and the second region 62 of the outer layer release liner 6 may be peeled off from the outer layer portion 3.

[0079] Next, as shown in Fig. 6(a), the tubular body T is sandwiched between the adhesive layer for polymerization 31 of the outer layer portion 3 and the adhesive layer for tubular body 40 of the tubular body locking portion 4, and the outer layer portion 3 is overlapped from the outside onto the inner layer portion 2. Finally, as shown in Fig. 6(b), the patch portion 8 is overlapped from the outside onto the outer layer portion 3, thereby fixing the tubular body T between the inner layer portion 2 and the outer layer portion 3. In this tubular body fixing device 1, the pair of patch portions 8 are arranged side by side in the longitudinal direction.

[0080] Hereinafter, the removal of the tubular body T from the tubular body fixing tool 1 will be described. First, as shown in Fig. 7(a), the tubular body T is fixed to the tubular body fixing tool 1, and then, as shown in Figs. 7(b) and 7(c), the outer layer portion 3 is peeled off from the tubular body T. In the tubular body fixing tool 1 of this embodiment, the outer layer portion 3 is provided with a peelable end portion 34, so that when the outer layer portion 3 is peeled off from the tubular body T, the outer layer portion 3 can be easily peeled off from the peelable end portion 34.

[0081] Furthermore, as shown in Fig. 8(a), the outer layer part 3 is peeled off until the tubular body T is exposed. In this tubular body fixing device 1, the non-adhesive part 41 is formed biased toward the leading separation side in the width direction in the tubular body engaging part 4, and the tubular body T is disposed at the position of the notch 410, so that when the outer layer part 3 is peeled off, only the tubular body T is exposed. By peeling off the outer layer part 3 in this manner, the tubular body T exposed from the outer layer part 3 can be removed from the tubular body fixing device 1 as shown in Fig. 8(b).

[0082] It should be noted that the tubular body fixing device of the present invention is not limited to the above-mentioned embodiment, and various modifications can be made without departing from the scope of the present invention. For example, the configuration of one embodiment can be added to the configuration of another embodiment, and part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Furthermore, part of the configuration of one embodiment can be deleted.

[0083] The tubular body locking portion 4 in the above embodiment is in the form of a sheet, but may be in other shapes, such as a plurality of dots or stripes spaced apart from one another.

[0084] Other than the shape and configuration of the tubular body pressure-sensitive adhesive layer 40 of the tubular body locking portion 4 in the tubular body fixture 1, the tubular body may be different from the above embodiment. Also, other than the shape and configuration of the inner layer release liner 5, the tubular body may be different from the above embodiment.

[0085] Furthermore, the tubular body fixing device 1 does not have to include at least one of the inner layer portion 2, the inner layer portion release liner 5, the outer layer portion release liner 6, the locking portion release liner 7, the patch portion 8, and the patch portion release liner 9. Furthermore, the shapes of the inner layer portion release liner 5, the outer layer portion release liner 6, the locking portion release liner 7, and the patch portion release liner 9 are not limited to those in the tubular body fixing device 1 of the above embodiment.
