The horizontal dimension of the tubular body fixture 1 of this embodiment is about 50 mm to 100 mm, for example, 100 mm. The dimension of the tubular body fixture 1 in the depth direction orthogonal to the horizontal direction is about 20 mm to 50 mm, for example, 50 mm.

The lower layer 2 is a sheet that can be applied on the skin. The lower layer 2 also has a lower surface 20 which is an adhesive surface 20 that can be applied onto the skin (see FIG. 2). The lower layer 2 of the present embodiment is an adhesive bandage, for example, an adhesive bandage having a nonwoven fabric such as Kinowhite (registered trademark of Nitto Denko Corporation, hereinafter the same) as a base layer. The lower layer 2 has a base layer 21 and an adhesive layer 22 which is arranged under the base layer 21 and whose lower surface constitutes the adhesive surface 20 of the lower layer 2 . In addition, in the lower layer 2 of the present embodiment, no adhesive layer is formed on the base material layer 21 . That is, the lower layer 2 has the adhesive surface 20 on one side (lower surface 20). The adhesive layer 22 contains glue that can be applied to the skin and does not easily cause rashes.

According to JIS Z0237, the adhesive surface 20 of the lower layer 2 is attached to a bakelite plate (phenolic resin plate) in an atmosphere of 23 ° C. and 50% relative humidity, crimped once with a 2 kg roller, and cured for 30 minutes.

When the lower layer 2 is Kinowhite, the adhesiveness of the adhesive surface 20 is, for example, 7N/19mm.

The upper layer 3 is a sheet that covers the lower layer 2 and the tubular body locking portion 4, and is, for example, a mesh sheet for good air permeability. The upper layer 3 of this embodiment is an adhesive bandage, for example, an adhesive bandage having the same nonwoven fabric as the lower layer 2, such as Kinowhite, as a base layer. Further, the upper layer 3 of the present embodiment has a base layer 33 and an adhesive layer 34 arranged under the base layer 33 and having a lower surface constituting a lower surface 35 of the upper layer 3 . That is, the upper layer 3 has the adhesive layer 34 on one surface (lower surface 35). Of the lower surface 35 of the upper layer 3, at least the region positioned above the tubular body engaging portion 4 in a state where it is attached to the tubular body engaging portion 4 is an adhesive surface. In the upper layer 3 of the present embodiment, the adhesive layer 34 is continuous throughout the horizontal direction, so the entire lower surface 35 of the upper layer 3 is the adhesive surface 35 . Although the adhesive layer 34 does not have to contain glue that can be attached to the skin, it preferably contains an odorless glue in consideration of the patient's comfort when using it.

The top layer 3 is separate from the bottom layer 2, for example to simplify manufacturing. Further, the upper layer 3 is connected to the lower layer 2 by affixing a portion of the adhesive layer 34 of the upper layer 3 that constitutes the one end portion 30 to the upper surface 23 of the lower layer 2 . Furthermore, before the tubular body T is fixed, the upper layer 3 includes at least one of the other end portion 31 (the right end portion in FIG. 2) in the horizontal direction, the one end portion 30, and an intermediate portion 32 positioned between the other end portion 31. For example, , is separated from the upper surface 23 of the lower layer 2 at both the other end 31 and the intermediate portion 32 . Specifically, the upper layer release liner 6 is arranged between the other end portion 31 and the intermediate portion 32 of the upper layer 3 and the lower layer 2 before the tubular body T is fixed.

The horizontal dimension of the upper layer 3 is smaller than the horizontal dimension of the lower layer 2 . The horizontal dimension of the one end portion 30 of the upper layer 3, that is, the horizontal dimension of the connecting portion of the upper layer 3 with the lower layer 2 is, for example, about 1/10 of the horizontal dimension of the lower layer 2. Furthermore, one horizontal edge 36 (the left edge in FIG. 2) of the upper layer 3 overlaps one horizontal edge 26 of the lower layer 2 in the vertical direction. The other horizontal edge 37 of the upper layer 3 (the right edge in FIG. 2) is located horizontally inside the other horizontal edge 27 of the lower layer 2 .

The tubular body locking portion 4 is a member that can lock the tubular body T while it is sandwiched between the lower layer 2 and the upper layer 3 . Further, the tubular body locking portion 4 is located on the upper surface 23 of the lower layer 2 at a position facing at least one of the other end portion 31 and the intermediate portion 32, for example, a position facing the intermediate portion 32 (a position facing the intermediate portion 32 of the upper layer 3). and between the bottom layer 2). Further, the tubular body locking portion 4 is arranged, for example, on an intermediate portion 24 of the lower layer 2 in the horizontal direction.

It should be noted that the tubular body locking portion 4 of the present embodiment is in the form of a rectangular sheet, and specifically, on the lower layer 2, it extends in a direction intersecting the horizontal direction, for example, in a depth direction orthogonal to the horizontal direction. there is Further, it is preferable that the horizontal dimension of the tubular body engaging portion 4 of the present embodiment is larger than the outer diameter of the tubular body T fixed to the tubular body fixture 1 . Further, the horizontal dimension of the tubular body engaging portion 4 is, for example, about 1/10 to 1/3 of the horizontal dimension of the lower layer 2 .

The tubular body engaging portion 4 has an adhesive surface 40 that contacts the tubular body T with the tubular body T sandwiched between the lower layer 2 and the upper layer 3 . The tubular body locking portion 4 of this embodiment is a double-sided tape having adhesive layers 42 and 43 provided on both sides of a base layer 41 . The tubular body locking portion 4 may be composed only of an adhesive layer (adhesive layer) (so-called base layer-less). The upper surface of the adhesive layer 42 arranged on the base material layer 41 is the adhesive surface 40 of the tubular body engaging portion 4 . The adhesive layers 42 and 43 may not contain glue that can be applied to the skin, but preferably contain odorless glue. The tubular body locking portion 4 is a tape that can be strongly contacted with an object and that can be peeled off (removed) after being attached, for example, 5000NS (product number of Nitto Denko Co., Ltd.). It is a resin tape. The material of the base material layer 41 has a high resistance to the tape peeling force, that is, has a strength that does not break against the peeling force. For example, the material of the base material layer 41 is a non-woven fabric or a resin film having excellent flexibility and high strength. Examples of the resin film include PET (polyethylene terephthalate).

According to JIS Z0237, the adhesive surface 40 of the tubular body locking portion 4 was attached to a stainless steel plate (SUS304BA plate) in an atmosphere of 23° C. temperature and 50% relative humidity, and crimped once with a 2 kg roller. After partial curing, the adhesiveness when peeled off at a tensile speed of 300 mm/min so as to be folded back 180° is preferably 8 N/19 mm or more, more preferably 12 N/19 mm or more, from the viewpoint of fixing the tubular body. When the tubular body locking portion 4 is 5000 NS, similarly, the adhesive surface 40 is 16 N/19 mm when the adhesive surface 40 is peeled back from the stainless steel plate by 180°.

At least one of the adhesiveness of the adhesive surface 40 of the tubular body engaging portion 4 and the adhesiveness of the adhesive surface 35 of the area of the lower surface of the upper layer 3 located above the tubular body engaging portion 4 is 2 is higher than that of the adhesive surface 20 of No. 2. From the "adhesiveness possessed by the adhesive surface 40 of the tubular body engaging portion 4" and the "adhesiveness possessed by the adhesive surface 35 of the area of the lower surface of the upper layer 3 located above the tubular body engaging portion 4" to the "adhesiveness possessed by the adhesive surface 40 of the lower layer 2" The difference after deducting the adhesiveness of the adhesive surface 20 is 1 N/19 mm or more, preferably 3 N/19 mm or more, and more preferably 5 N/19 mm or more. In the tubular body fixture 1 of the present embodiment, the adhesive surface 40 of the tubular body locking portion 4 has higher adhesiveness than the adhesive surface 20 of the lower layer 2 .

When the tubular body T is fixed by adhering the adhesive surface 40 of the tubular body locking portion 4 and the adhesive surface 35 of the upper layer 3 together, the tubular body fixing shear force is preferably 15 N or more, and more preferably 20 N or more. It is preferably, for example, about 25N to 30N. The tubular body fixing shear force is measured by attaching a tubular body fixture 1 having a depth direction of 20 mm perpendicular to the horizontal direction to a flat plate made of Bakelite, and measuring a tubular body made of PVC material having an outer diameter of 4 mm and an inner diameter of 2.5 mm (for example, stock JV-ND2050LE manufactured by the company JMS) is fixed to the fixing part in the usage method of the tubular body fixture 1 described later, and the tubular body is pulled in the length direction of the tubular body at a tensile speed of 300 mm / min (the tubular body and A method of measuring the adhesiveness in the shear direction between the adhesive surface 40 and the adhesive surface 35 and reading the maximum value).

The lower layer release liner 5, the upper layer release liner 6, and the locking part release liner 7 are, respectively, the adhesive surface 20 of the adhesive layer 22 of the lower layer 2, the adhesive surface 35 of the adhesive layer 34 of the upper layer 3, and the tubular body locking part. It is a protective material for the adhesive surface 40 of the adhesive layer 42 of the part 4, and is, for example, release paper. Since the lower layer release liner 5 is provided with the slits 50 , the lower layer release liner 5 can be easily peeled off from the lower layer 2 . Alternatively, by partially peeling off the lower layer release liner 5, the lower layer 2 is partially attached to the skin, and then the remaining lower layer release liner 5 is peeled off to attach the entire lower layer 2 to the skin S. , the lower layer 2 can also be temporarily fixed. Note that the slit 50 overlaps, for example, in the vertical direction with respect to the boundary between the one end portion 25, which is a connection portion of the lower layer 2 with the upper layer 3, and the non-connection portion (for example, the intermediate portion 24) of the lower layer 2 with respect to the upper layer 3. placed in the part.

Next, a method for using the tubular body fixture 1 will be specifically described. First, the lower layer release liner 5 is removed from the lower layer 2 of the tubular body fixture 1, and the lower layer 2 is attached onto the skin S as shown in FIG. 3(a). Next, the locking portion release liner 7 is peeled off from the tubular body locking portion 4 and removed, and the tubular body T is placed on the adhesive surface 40 of the tubular body locking portion 4 as shown in FIG. 3(b). At this time, in the tubular body fixture 1 of the present embodiment, the tubular body T is placed on the adhesive surface 40 of the central region 44 positioned at the center of the tubular body locking portion 4 in the horizontal direction. At this time, the tubular body T is fixed to the lower layer 2 by the adhesive force of the adhesive surface 40 of the tubular body locking portion 4 . Thereby, the tubular body T can be temporarily fixed to the lower layer 2 .

Further, the upper layer release liner 6 is peeled off from the upper layer 3 and removed, and as shown in FIG. As shown in 3(d), the tubular body T is fixed between the lower layer 2 and the upper layer 3 by stacking the upper layer 3 on the lower layer 2 from above. At this time, in the tubular body fixture 1 of the present embodiment, by pressing the intermediate portion 32 of the upper layer 3 downward, the adhesive surface 35 of the first portion 321 overlapping the tubular body locking portion 4 of the intermediate portion 32 of the upper layer 3 is removed. contact the adhesive surface 40 of the tubular body engaging portion 4 to fix both the adhesive surfaces 35 and 40 . As a result, the tubular body T is fixed in a state of being sandwiched between the upper layer 3 and the tubular body engaging portion 4 at the first portion 321 of the intermediate portion 32 of the upper layer 3 .

In addition, in the tubular body fixture 1 of the present embodiment, the dimension of the tubular body engaging portion 4 in the horizontal direction is larger than the outer diameter of the tubular body T. As shown in FIG. Therefore, in a state where the tubular body T is fixed to the tubular body fixture 1, the regions located near both sides of the tubular body T in the horizontal direction do not overlap with the tubular body T of the intermediate portion 32 of the upper layer 3 and are tubular. The adhesive surface 35 of the second portion 322 overlapping both ends 45 of the body engaging portion 4 in the horizontal direction and the adhesive surface 40 of the tubular body engaging portion 4 come into contact with each other.

In addition, in the tubular body fixture 1 of the present embodiment, by pressing the intermediate portion 32 of the upper layer 3 downward, the adhesive surface 35 of the third portion 323 that does not overlap the tubular body locking portion 4 of the intermediate portion 32 of the upper layer 3 is removed. and the upper surface 23 of the lower layer 2 are in contact with each other. As a result, the upper layer 3 and the lower layer 2 are connected at the third portion 323 of the intermediate portion 32 of the upper layer 3 as well.

Furthermore, in the tubular body fixture 1 of the present embodiment, by pressing the other end 31 of the upper layer 3 downward, the adhesive surface 35 of the other end 31 of the upper layer 3 and the upper surface 23 of the lower layer 2 come into contact.

Thus, in the tubular body fixture 1 of this embodiment, when the tubular body T is fixed, the upper layer 3 and the lower layer 2 are connected at both the one end 30 and the other end 31 of the upper layer 3 . Moreover, in the tubular body fixture 1 of the present embodiment, when the tubular body T is fixed, the upper layer 3 and the lower layer 2 are connected also at the third portion 323 of the intermediate portion 32 of the upper layer 3 .

In addition, in the tubular body fixture 1 of the present embodiment, when the tubular body T is fixed, one horizontal edge 36 of the upper layer 3 (the left edge in FIG. 3(d)) corresponds to one horizontal edge of the lower layer 2. 26 in the vertical direction, the other horizontal edge 37 of the upper layer 3 (the right edge in FIG. 3(d)) is horizontally inside the other horizontal edge 27 of the lower layer 2 (FIG. 3 ( d) on the left).

According to the tubular body fixture 1 described above, the tubular body T is sandwiched between the adhesive surface 40 of the tubular body locking portion 4 and the adhesive surface 35 of the upper layer 3, and the adhesive surfaces 40 and 35 are fixed ( For example, it is fixed between the lower layer 2 and the upper layer 3 by fixing the adhesive surface 40 of the tubular body engaging portion 4 and the adhesive surface 35 of the second portion 322 of the intermediate portion 32 of the upper layer 3 . As a result, the adhesion between the adhesive surfaces 40 and 35 in the vicinity of the tubular body T is less likely to come off, so that the upper layer 3 is less likely to separate from the lower layer 2, and the tubular body T is removed from between the lower layer 2 and the upper layer 3. Also, since a large resistance is generated in the tubular body T, the tubular body T is difficult to be pulled out. In particular, when it is difficult to make a normal judgment, such as when the patient has dementia, the tubular body fixing device 1 is useful because there is a higher risk of the tubular body T being pulled out. Moreover, if the tubular bodies T have substantially the same diameter as the tubular body locking portion 4 in the horizontal direction or have a smaller diameter than the horizontal dimension of the tubular body locking portion 4, the tubular bodies T having different sizes can be combined into tubular bodies T. Since it can be arranged on the body engaging portion 4, it is possible to fix tubular bodies T of various sizes on the skin S with one tubular body fixture 1. FIG.

In the tubular body fixture 1 of this embodiment, the adhesive surface 40 of the tubular body locking portion 4 has higher adhesiveness than the adhesive surface 20 of the lower layer 2. Fixation of the tubular body T between the lower layer 2 and the upper layer 3 can be ensured. Further, when the tubular body T is fixed by adhering the adhesive surface 40 of the tubular body locking portion 4 and the adhesive surface 35 of the upper layer 3 together, the tubular body fixing shear force is 15 N or more. can be fixed.

In addition, in the tubular body fixture 1 of the present embodiment, when the tubular body T is fixed between the lower layer 2 and the upper layer 3, as shown in FIG. It is located inside the other edge 27 of the lower layer 2 in the horizontal direction, and the other edge 27 of the lower layer 2 is not covered with the upper layer 3 and is exposed. As a result, in a state where the tubular body fixing device 1 is attached to the skin S, the other end portion 31 can be easily pinched by putting a finger on the other end edge 37 of the upper layer 3, and the upper layer 3 can be removed from the lower layer. 2, the tubular body T can be easily removed from the tubular body fixture 1 after the upper layer 3 is peeled off from the lower layer 2.例文帳に追加

Furthermore, in the tubular body fixture 1 of the present embodiment, the tubular body locking portion 4 extends in a direction that intersects the horizontal direction. and the direction perpendicular to the horizontal direction in this embodiment), even if the lower layer 2 is pulled in this direction (arrow direction in FIG. and the upper layer 3.

In the tubular body fixture 1 of the present embodiment, the base material layer 41 of the tubular body locking portion 4 is made of a material that is difficult to break, such as PET. The material layer 41 is not broken, and fragments of the base material layer 41 are less likely to remain in the tubular body T. Therefore, when the tubular body T is reused after being removed from the tubular body fixture 1, the tubular body T can be easily reused. In addition, by using a removable double-faced tape such as 5000NS as the tubular body locking portion 4, when the tubular body T is removed from the tubular body fixture 1, the adhesive layers 42 and 43 of the adhesive layers 42 and 43 adhere to the tubular body T. is hard to remain.

Further, in the tubular body fixture 1 of the present embodiment, the tubular body locking portion 4 is arranged on the intermediate portion 24 in the horizontal direction of the lower layer 2, and in the central region 44 of the tubular body locking portion 4 in the horizontal direction, Since the tubular body T is fixed in a placed state, the tubular body T can be stably fixed in the center region of the tubular body fixture 1 in the horizontal direction. Therefore, even if the patient moves his or her body, the tubular body T is less likely to shift.

It should be noted that the tubular body fixture of the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist 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, some of the configurations of certain embodiments can be deleted.

The tubular body fixture 1 of the above-described embodiment is a sheet that has a rectangular shape when viewed from a direction substantially perpendicular to the upper layer 3. It may be a sheet having a polygonal shape, and is a continuum 100 extending in a direction intersecting the horizontal direction, for example, in a depth direction orthogonal to the horizontal direction (left and right direction in FIG. 5) as shown in FIG. good too. In such a continuum, since the continuum 100 can be cut with different dimensions in this extending direction (direction intersecting with the horizontal direction), one continuum 100 can be cut, for example, a tubular body in the patient's skin S It is possible to obtain the tubular body fixture 1 having desired dimensions according to the size of the area of the site to which T is to be fixed and the strength of fixing of the tubular body T. Further, as shown in FIG. 6, the continuous body 100 can be stored and transported in a rolled state.

The tubular body fixture 1 does not have to include at least one of the lower layer release liner 5 , the upper layer release liner 6 , and the locking portion release liner 7 . For example, if the continuous body 100 does not include the lower layer release liner 5, the adhesive surface 20 of the lower layer 2 sticks to the upper surface of the upper layer 3 when rolled into a roll, so the roll shape collapses during storage and transportation. Hateful.

In addition, in the tubular body fixture 1 of the above-described embodiment, the horizontal dimension of the connecting portion between the upper layer 3 and the lower layer 2 was about 1/10 of the horizontal dimension of the entire upper layer 3. It may be about 1/3. For example, as shown in FIG. 7, it may be about 1/3.

Furthermore, in the tubular body fixture 1 of the above-described embodiment, one horizontal edge 36 of the upper layer 3 overlaps one horizontal edge 26 of the lower layer 2 in the vertical direction, while the other edge 37 of the upper layer 3 overlaps the lower layer. 2, the one edge 36 of the upper layer 3 and the one edge 26 of the lower layer 2, and the other edge 37 of the upper layer 3 and the other edge 27 of the lower layer 2 may overlap each other in the vertical direction. In this case as well, when the tubular body T is fixed by the tubular body fixture 1, the upper layer 3 covers the tubular body T, so that the other edge 37 of the upper layer 3 is more horizontal than the other edge 27 of the lower layer 2. Since it is positioned inside in the direction, the other end 31 of the upper layer 3 can be easily picked up, and the tubular body T can be easily removed from the tubular body fixture 1 .

In the state where the tubular body T is fixed by the tubular body fixture 1, the one end edge 36 of the upper layer 3 may be located inside the one end edge 26 of the lower layer 2 in the horizontal direction. In this case, the horizontal dimension of the upper layer 3 may be smaller than the horizontal dimension of the lower layer 2 or the same as the horizontal dimension of the lower layer 2 . For example, if both the one end edge 36 and the other end edge 37 of the upper layer 3 are located inside the one end edge 26 and the other end edge 27 of the lower layer 2 in the horizontal direction, respectively, the upper layer 3 Since one end 30 and the other end 31 of the can be pinched, the tubular body T can be easily removed.

Although the upper layer 3 in the above embodiment is separate from the lower layer 2, it may be integrated with the lower layer. For example, as shown in FIG. The upper layer 3 and the lower layer 2 may be connected by folding the layers in a state of being arranged. In this case, the tubular body fixture 1 may be attached to the skin S by providing an adhesive layer on the lower surface of the lower layer 2 . Moreover, although the upper layer 3 in the above embodiment is connected to the upper surface 23 of the lower layer 2 , the upper layer 3 may be connected to a portion other than the upper surface 23 of the lower layer 2 .

The adhesiveness of the adhesive surface 40 of the tubular body locking portion 4 in the above-described embodiment was higher than the adhesiveness of the lower surface 20 of the lower layer 2, but it may be lower than the adhesiveness of the lower surface 20 of the lower layer 2. It may be the same as the tackiness of the lower surface 20 of 2. Even in such a case, since the tubular body T is fixed between the lower layer 2 and the upper layer 3 by fixing the adhesive surfaces 40 and 35 to each other, it is possible to fix the adhesive surfaces 40 and 35 to each other in the vicinity of the tubular body T. Since it is hard to come off, the upper layer 3 is hard to separate from the lower layer 2, and the tubular body T is hard to be pulled out from between the lower layer 2 and the upper layer 3. - 特許庁In addition, since the adhesive surface 40 of the tubular body locking portion 4 has low adhesiveness, even if the tubular body T is placed in the wrong position when the tubular body T is placed on the tubular body locking portion 4, , it is easy to remove the tubular body T once and place it again. When Kinowhite with the adhesive surface facing upward is arranged on the lower layer 2 as the tubular body locking portion 4, the adhesive surface 40 of the tubular body locking portion 4 and the adhesive surface 35 of the upper layer 3 are attached. The tubular body fixing shear force when the tubular body T is fixed together is, for example, 22N to 25N.

Note that if the adhesive surface 40 of the tubular body engaging portion 4 has a lower adhesiveness than the lower surface 20 of the lower layer 2 or has the same adhesiveness as the lower surface 20 of the lower layer 2, the upper layer 3 The adhesiveness of the adhesive surface 35 in the region of the lower surface located above the tubular body engaging portion 4 may be higher than the adhesiveness of the lower surface 20 of the lower layer 2 . Thus, at least one of the adhesiveness of the adhesive surface 40 of the tubular body engaging portion 4 and the adhesiveness of the adhesive surface 35 of the area of the lower surface of the upper layer 3 located above the tubular body engaging portion 4 However, if the adhesiveness is higher than that of the lower surface 20 of the lower layer 2, the tubular body T can be fixed between the lower layer 2 and the upper layer 3 by the highly adhesive adhesive layer.

Further, the tubular body engaging portion 4 in the above embodiment has a rectangular sheet shape, but may have other shapes such as a plurality of mutually spaced dots or stripes. Furthermore, the tubular body engaging portion 4 of the above embodiment was arranged between the intermediate portion 32 of the upper layer 3 and the lower layer 2, but it is located between the other end portion 31 of the upper layer 3 and the lower layer 2 or between the intermediate portion 32. and the other end 31 and the lower layer 2 . In this case, the lower layer 2 will have adhesive surfaces on both sides (lower surface 20 and upper surface 23). It should be noted that the tubular body locking portion 4 may be composed of only the adhesive layer 42 without the base material layer as described above. good. When the adhesive contained in the adhesive layer of Kinowhite is applied on the lower layer 2 as the tubular body engaging portion 4, the adhesive surface 40 of the tubular body engaging portion 4 (in this configuration, the glue applied on the lower layer 2 The adhesive surface of the upper layer 3) and the adhesive surface 35 of the upper layer 3 are bonded together, and the shear force for fixing the tubular body is, for example, 20N to 23N.
