Note that FIG. 13 is a schematic plan view (a diagram corresponding to FIG. 6B) showing a state in which the first member 110, the second member 120', and the third member 130 are attached.

The catheter fixture 100'is a replacement of the second member 120 included in the catheter fixture 100 with a second member 120'.

Since the catheter fixture 100'is used in substantially the same procedure as the catheter fixture 100, the description will be omitted as appropriate.

First, the catheter 5 is punctured on the body surface, and the first member 110 is inserted under the catheter 5. At this time, the first member 110 is attached to the body surface by the adhesive layer 31b on the bottom surface of the first base 111, and the catheter 5 is attached to the first base 111 by the adhesive layer 31a on the upper surface of the first base 111.

The presence of the pressure-sensitive adhesive layer 31a on the upper surface of the first base 111 allows the catheter 5 to be temporarily fixed at the stage when the catheter 5 is placed on the first base 111, and the catheter 5 can be temporarily fixed from the puncture portion 51. It becomes difficult to pull out. By temporarily fixing the catheter 5 with the first member 110, the subsequent fixing work can be performed with peace of mind.

Next, the second member 120'is attached onto the catheter 5. At this time, the second member 120'is attached to the body surface by the adhesive layer 32'on the bottom surface of each of the four extending portions 122a', 122b', 122c', and 122d'. Further, the first member 110 and the second member 120'are formed by at least the pressure-sensitive adhesive layer 31a on the upper surface of the first base 111 and the pressure-sensitive adhesive layer 32'on the bottom surface of the second base 121'. It is pasted together so as to sandwich a part. When the adhesive layer 31a on the upper surface of the first member 110 and the adhesive layer 32'on the bottom surface of the second member 120'are attached so as to sandwich at least a part of the catheter 5, the catheter 5 is attached in the vertical direction (± P1). Axial direction, in addition, + P1 axis direction is a downward arrow in FIG. 13, preferably up / down / left / right direction (± P1 axis direction and ± P2 axis direction, and + P1 axis direction is an arrow pointing to the right in FIG. 13). , More preferably, the circumference 360 degrees is surrounded by the pressure-sensitive adhesive layer.

It is more preferable that the catheter is affixed to the body surface so as to be located on both sides of the 51, that is, to be located at least a part of the outer periphery of the catheter puncture portion 51 that punctures the catheter 5. By attaching the two extending portions 122a'and 122b' to the body surface so as to be located on both sides of the puncture portion 51 of the catheter 5, the catheter 5 moves in the direction of exiting the puncture portion 51 after fixing the catheter 5. At that time, the two extending portions 122a'and 122b' provide resistance, which makes it difficult for the catheter 5 to come off. In addition, the expansion and contraction of the skin around the puncture portion 51 of the catheter 5 can be suppressed.

Further, when the two extending portions 122a'and 122b' are attached to the body surface so as to be located on both sides of the puncture portion 51 of the catheter 5 (± P2 axial direction), the two extending portions 122c' And 122d'extended in the P2 axis direction which is substantially perpendicular to the P1 axis in a plan view from the body surface side (more specifically, the extending portion 122c' extends in the −P2 axis direction (FIG. 13). Since the catheter 5 is attached to the body surface in a state of extending in the left direction) and extending in the + P2 axis direction (in a state of extending in the right direction in FIG. 13), the catheter 5 is attached. After fixation, when a force in a direction intersecting the direction in which the catheter 5 comes out is applied, the two extending portions 122c'and 122d' give a resistance force, so that the catheter 5 is less likely to shift laterally. In addition, the expansion and contraction of the skin around the puncture portion 51 of the catheter 5 can be suppressed.

Finally, the third member 130 is attached on the second member 120'. At this time, the third member 130 is attached to the body surface by the adhesive layer 33 on the bottom surface of the frame portion 132, and the second member 120'and the third member 130 are attached to the adhesive layer on the bottom surface of the frame portion 132.

By attaching the frame portion 132 so as not to cover the connecting member 53 of the catheter 5, it is possible to suppress the occurrence of floating between the catheter 5 and the third member 130 and further suppress the movement of the catheter 5. .. Further, by covering only the catheter hub 52 with the second base portion 121', it is possible to easily separate the connection between the catheter hub 52 and the connecting member 53.

<6. How to use the catheter fixture 100-15>
Hereinafter, an example of how to use the catheter fixture 100-15 of the modified example of the first embodiment will be described with reference to FIG. Note that FIG. 15 is a schematic plan view (a diagram corresponding to FIG. 6B) showing a state in which the first member 110, the second member 120-14, and the third member 130 are attached.

The catheter fixture 100-15 replaces the second member 120 included in the catheter fixture 100 with the second member 120-14.

Since the catheter fixture 100-15 is used in substantially the same procedure as the catheter fixture 100, the description thereof will be omitted as appropriate.

First, the tip portion 51-1 of the catheter constituting the catheter 5 is punctured on the body surface, and the first member 110 is inserted under the catheter 5. At this time, the first member 110 is attached to the body surface by the adhesive layer 31b on the bottom surface of the first base 111, and the catheter 5 is attached to the first base 111 by the adhesive layer 31a on the upper surface of the first base 111. It is fixed. The presence of the pressure-sensitive adhesive layer 31a on the upper surface of the first base 111 allows the catheter 5 to be temporarily fixed at the stage when the catheter 5 is placed on the first base 111, and the catheter 5 can be temporarily fixed from the puncture portion 51. It becomes difficult to pull out. By temporarily fixing the catheter 5 with the first member 110, the subsequent fixing work can be performed with peace of mind.

Next, the second member 120-14 is attached onto the catheter 5 so that the catheter puncture portion 51 that punctures the catheter 5 can be visually recognized. The first member 110 and the second member 120-14 are catheterized by an adhesive layer 31a on the upper surface of the first base 111 and an adhesive layer 32-14 on the bottom surface of the second base 120-14-1. It is bonded so as to sandwich at least a part of 5. The pressure-sensitive adhesive layer 31a on the upper surface of the first member 110 and the second member 120-14 (second base portion 120-14-1) also sandwich at least a part of the catheter 5 between the pressure-sensitive adhesive layer 32-102 on the bottom surface. When attached in this way, the catheter 5 is surrounded by an adhesive layer in the vertical direction, preferably in the vertical and horizontal directions, and more preferably around 360 degrees. Therefore, the catheter 5 becomes difficult to come off from the puncture portion 51, and the catheter 5 can be reliably fixed.

It is preferable that the second member 120-14 is attached so that the second base portion 120-14-1 does not cover the connecting member 53 of the catheter 5 and does not cover the puncture portion 51 of the catheter 5. By attaching the second base 120-14-1 so as not to cover the connecting member 53 of the catheter 5, the catheter 5 is prevented from floating between the catheter 5 and the second member 120-14. The movement of the can be suppressed more. Further, by covering only the catheter hub 52 with the second base portion 120-14-1, the connection between the catheter hub 52 and the connecting member 53 can be easily separated.

Finally, the third member 130 is attached on the second member 120-14. At this time, the third member 130 is attached to the body surface by the adhesive layer 33 on the bottom surface of the frame portion 132, and the second member 120'and the third member 130 are attached to the adhesive layer on the bottom surface of the frame portion 132. It is bonded by 33. By attaching the third member 130, the puncture portion 51 of the catheter 5 can be protected. Further, by providing the window portion 131 on the third member 130, the visibility of the puncture portion 51 can be ensured.

The third member 130 is preferably attached so that the frame portion 132 does not cover the connecting member 53 of the catheter 5 and does not cover the puncture portion 51 of the catheter 5. By attaching the frame portion 132 so as not to cover the connecting member 53 of the catheter 5, it is possible to suppress the occurrence of floating between the catheter 5 and the third member 130 and further suppress the movement of the catheter 5. .. Further, by covering only the catheter hub 52 with the second base portion 120-14-1, the connection between the catheter hub 52 and the connecting member 53 can be easily separated.

The method of fixing the catheter in the present embodiment and the modified example is described in the following steps (a) to (d);
(A) The process of attaching the first member to the body surface and
(B) A step of fixing the catheter to the first base with an adhesive layer on the upper surface of the first base.
(C) The process of attaching the second member on the catheter and
(D) It has at least a step of attaching the second member to the body surface with an adhesive layer on the bottom surface of a plurality of extending portions of the second member.
In the step (c), the first member and the second member sandwich at least a part of the catheter between the adhesive layer on the upper surface of the first base and the adhesive layer on the bottom surface of the second base. It is pasted on.

The method may further include (e) a step of attaching the third member on the second member, and in the above step (e), the third member is an adhesive layer on the bottom surface of the frame portion. It is preferable that the second member and the third member are attached to the body surface by the adhesive layer on the bottom surface of the frame portion. When the third member is not used, for example, on the surface of the second member (for example, the second member 120, the second member 120') (for example, the surface opposite to the body surface side), for example. By attaching a transparent film tape, a window portion may be formed between a plurality of extending portions. In this case, the visibility of the puncture portion can be ensured while protecting the puncture portion of the catheter, and further, since the third member is not used, the fixed pair product can be made smaller, and the skin can be expanded and contracted. Makes it easier to follow.

Further, in the step (d), a plurality of extending portions (plurality of first extending portions) of the second member (second member 120 or second member 120') are provided on both sides of the puncture portion of the catheter. It is preferable that the catheter is affixed to the surface of the body so as to be located at at least a part of the outer periphery of the catheter puncture portion through which the catheter is punctured. Then, in a plan view from the body surface side, the plurality of extending portions (plurality of first extending portions) preferably extend in the puncturing direction starting from the outer periphery of the catheter puncturing portion. Therefore, the distance between the plurality of extending portions (plurality of the first extending portions) becomes longer (each of the plurality of extending portions (plurality of the first extending portions) is separated from each other). preferable. Even if the plurality of extending portions (plurality of the first extending portions) extend in the puncture direction starting from the outer periphery of the catheter puncturing portion 51, the plurality of extending portions (plurality of the first extending portions) may be extended. The distance between the existing parts) may be substantially constant.

Further, in the step (d), the plurality of extending portions (plurality of the second extending portions) of the second member (second member 120 or the second member 120') are from the body surface side. In plan view, it is preferable to extend in a direction substantially perpendicular to the puncture direction of the catheter. Then, the plurality of extending portions (plurality of the second extending portions) of the second member (second member 120 or the second member 120') puncture the catheter in a plan view from the body surface side. It may extend in the direction substantially opposite to the direction. In this case, as the plurality of extension portions (plurality of second extension portions) extend, the distance between the plurality of extension portions (plurality of second extension portions) may increase. (The plurality of extension portions (plurality of second extension portions) may be separated from each other), and the distance between the plurality of extension portions (plurality of second extension portions) is substantially constant. But it may be.

As described above, the catheter fixture of the present embodiment can prevent the catheter from pressing the body surface and causing pain by arranging the first member between the body surface and the catheter. Therefore, it is possible to reduce the burden on the body surface when the catheter is fixed.

Further, in the catheter fixture of the present embodiment, since the adhesive layer is provided on the upper surface of the first base, the catheter can be temporarily fixed at the stage when the catheter is placed on the first base, and the catheter can be fixed. Becomes difficult to remove from the puncture site. By temporarily fixing the catheter with the first member, the subsequent fixing work can be performed with peace of mind.

Further, in the catheter fixture of the present embodiment, the first member and the second member have at least one of the catheters by the pressure-sensitive adhesive layer on the upper surface of the first base and the pressure-sensitive adhesive layer on the bottom surface of the second base. By being bonded so as to sandwich the portion, the catheter is surrounded by the adhesive layer in the vertical direction, preferably in the vertical / horizontal direction, and more preferably 360 degrees around the catheter, so that the catheter is difficult to come off from the puncture portion, and the catheter can be moved. It can be securely fixed.

Then, in the catheter fixture of the present embodiment, the plurality of extending portions (first extending portions) of the second member are located on both sides of the catheter puncturing portion, that is, around the outer circumference of the catheter puncturing portion. By being attached to the surface of the body so as to be located at least in a part of the body, it becomes difficult for the catheter to come off after the catheter is fixed, and the expansion and contraction of the skin around the puncture portion of the catheter can be suppressed.

Further, in the catheter fixture of the present embodiment, the plurality of extending portions (second extending portions) of the second member are in the first direction (in-plane of the second base and the plurality of first extending portions). Attached to the body surface in a state of extending to the second direction side orthogonal to the direction extending between the portions) or to the side opposite to the plurality of first extending portions sides (minus side in the first direction). As a result, the catheter is less likely to shift laterally after the catheter is fixed, and the expansion and contraction of the skin around the puncture portion of the catheter can be suppressed.

In the catheter fixture of the present embodiment, the third member having the window portion is further attached, so that the visibility of the puncture portion can be ensured while protecting the puncture portion of the catheter.

The catheter fixture of the present embodiment is preferably intended for children (0 to 15 years old), especially from newborns to younger children (0 to 5 years old). Conventionally, subjects from newborns to children under elementary school age (0 to 5 years old) have a very small area of the back of the hand where the catheter is to be fixed, and there is no suitable catheter fixing device. It was necessary to stack and fix the sheets. Therefore, the fixing work is complicated, and it is difficult to obtain a stable fixing force every time. In addition, since the subject often resists and moves when fixing the catheter, there are many troubles that the catheter comes off, and medical staff such as nurses feel anxious every time when fixing the catheter. I was going.

However, in the catheter fixture of the present embodiment, the catheter can be temporarily fixed at the stage where the first member is inserted under the catheter and the catheter is placed on the first base, and the catheter is the puncture portion. It becomes difficult to pull out from. Therefore, the catheter fixing work can be performed with peace of mind.

Further, in the catheter fixture of the present embodiment, the first member and the second member have at least one of the catheters by the pressure-sensitive adhesive layer on the upper surface of the first base and the pressure-sensitive adhesive layer on the bottom surface of the second base. By being bonded so as to sandwich the portion, the catheter is surrounded by the adhesive layer in the vertical direction, preferably in the vertical / horizontal direction, and more preferably 360 degrees around the catheter, so that the catheter is difficult to come off from the puncture portion. Therefore, even from a newborn baby with a small area of the back of the hand, which is a part to be fixed, to a child under elementary school age, a strong fixing force can be obtained with a small area to be fixed.

From the above, the catheter fixture of the present embodiment can be suitably used as a catheter fixture for children because the catheter can be securely and securely fixed while reducing the burden on the body surface.

<2. How to use the catheter fixture 300>
Hereinafter, an example of how to use the catheter fixture 300 of the present embodiment will be described with reference to FIG. Note that FIG. 17 is a schematic plan view showing a state in which the first member 110, the third member 130', and the fourth member 140 are attached.

Since the catheter fixture 300 is used in substantially the same procedure as the catheter fixture 100 (except for the step of mounting the second member 120), the description will be omitted as appropriate.

First, the catheter 5 is punctured on the body surface, and the first member 110 is inserted under the catheter 5. At this time, the first member 110 is attached to the body surface by the adhesive layer 31b on the bottom surface of the first base 111, and the catheter 5 is attached to the first base 111 by the adhesive layer 31a on the upper surface of the first base 111. It is fixed. The presence of the pressure-sensitive adhesive layer 31a on the upper surface of the first base 111 allows the catheter 5 to be temporarily fixed at the stage when the catheter 5 is placed on the first base 111, and the catheter 5 can be temporarily fixed from the puncture portion 51. It becomes difficult to pull out. By temporarily fixing the catheter 5 with the first member 110, the subsequent fixing work can be performed with peace of mind.

Next, the third member 130'is attached on the first member 110. At this time, the third member 130'is attached to the body surface by the adhesive layer 33 on the bottom surface of the frame portion 132', and the first member 110 and the third member 130' are attached to the upper surface of the first base portion 111. The adhesive layer 31a and the adhesive layer 33 on the bottom surface of the frame portion 132'are attached so as to sandwich at least a part of the catheter 5. When the adhesive layer 31a on the upper surface of the first member 110 and the adhesive layer 33 on the bottom surface of the third member 130'are attached so as to sandwich at least a part of the catheter 5, the catheter 5 is attached in the vertical direction, preferably up and down. The adhesive layer surrounds the surface in the left-right direction, more preferably 360 degrees. Therefore, the catheter 5 becomes difficult to come off from the puncture portion 51, and the catheter 5 can be reliably fixed.

By attaching the fourth member 140 so as to cover the connecting member 53 of the catheter 5, the movement of the catheter 5 in the width direction can be further suppressed. Further, when separating the connection between the catheter hub 52 and the connecting member 53 by covering only the catheter hub 52 with the frame portion 132', only the fourth member 140 needs to be peeled off to facilitate the separation. Can be done.

When the fourth member 140 has recesses 141a and 141b, it is preferable that the recesses 141a and 141b are attached so as to follow the shape of the catheter 5. The recessed portions 141a and 141b make it easy to align the fourth member 140 with the catheter 5, and further, it can be attached along the shape, so that floating is less likely to occur between the body surface and the catheter 5. The movement of the catheter 5 in the width direction can be further suppressed.
