A notch portion C1 is provided. Further, the tubular body fixture 1 can be provided with a second notch portion C2, a third notch portion C3, a release sheet 2, and the like. Hereinafter, each part will be described in detail.

(1) Skin fixing part 11
The skin fixing portion 11 is a portion for fixing the tubular body fixing device 1 to the skin. The shape of the skin fixing portion 11 may be, for example, a circular shape, an elliptical shape, a polygonal shape such as a triangle, a square, a rectangle, or a rhombus, or a shape in which these shapes are appropriately combined, depending on the portion to which the tubular body is fixed. be able to. Specifically, the tubular body fixing tool according to the first embodiment shown in FIG. 1 may have a substantially square shape with rounded corners, or the tubular body fixing tool according to the second embodiment shown in FIG. It is also possible to have a substantially square shape as in 1. In this technique, it is particularly preferable to form a shape without corners. By making a circle without corners, an oval shape, a polygon with rounded corners, or a shape that combines these shapes, it is possible to prevent it from peeling off from the skin, and the area to be attached to the skin is small, so it is irritating to the skin. Can exert the effect of reducing.

The area of the skin fixing portion 11 can be specified according to the site where the tubular body is fixed. For example, when a nasal catheter is fixed as a tubular body, the skin fixing portion 11 is fixed to a portion extending from the bridge of the nose to the tip of the nose, so the area is preferably 1 to 12 cm ² and 2 to 10 cm ² . The area is more preferable. Further, for example, when a tubular body (abdominal cavity drain, chest tube, urethral catheter, venous catheter, etc.) used for the body part is fixed, the skin fixing part 11 is fixed to the body part, so that the area is 5 to 60 cm ² . It is preferable that the area is 10 to 30 cm ² , and it is more preferable that the area is 10 to 30 cm 2.

Further, in the relationship between the tubular body fixing portion 12 and the tubular body angle adjusting portion 13, which will be described later, the area of the skin fixing portion 11 and the total area of the tubular body fixing portion 12 and the tubular body angle adjusting portion 13 are 1: 1. It is preferable to set it to -4. By setting such an area ratio, it is possible to prevent the tubular body fixative 1 from peeling off from the skin and to fix it to the body surface more stably.

(2) Tubular body fixing portion 12
The tubular body fixing portion 12 is a portion connected to the skin fixing portion 11 and wound and fixed to the tubular body. Further, the tubular body fixing portion 12 is provided in a state of facing the tubular body angle adjusting portion 13 described later with a gap thereof. By providing a gap between the tubular body fixing portion 12 and the tubular body angle adjusting portion 13, when the tubular body fixing portion 12 is wound around the tubular body, the operation is hindered by the tubular body angle adjusting portion 13. Can be prevented. The tubular body fixing portion 12 is provided with a first notch portion C1 on the gap side.

FIG. 3 is a conceptual diagram showing a method of winding and fixing a tubular body with a tubular body fixing portion 12. With the first notch C1 of the tubular body fixing portion 12 in contact with the tubular body (see FIG. 3A), the tubular body fixing portion 12 is passed from under the tubular body and wound around (see FIG. 3B). , The tubular body can be fixed. In the present technique, first, the cutout portion C1 serves as the starting point for winding around the tubular body, so that highly reproducible fixing at the same position is possible regardless of the procedure of the medical staff. Further, since the notch portion C1 is along the outer wall surface of the tubular body, the tension applied to the tubular body fixing portion 12 at the time of winding can be relaxed, and the occurrence of wrinkles and twitching can be prevented, and the appearance is good and smooth. The tubular body fixing portion 12 can be wound around the tubular body. As a result, highly stable fixing becomes possible.

The form of the tubular body fixing portion 12 is not particularly limited as long as it can be wound around the tubular body, but it is preferably a band-shaped form from the viewpoint of ease of winding. The length of the tubular body fixing portion 12 in the longitudinal direction (see reference numeral L1 in FIG. 1, the same applies hereinafter) is preferably in the range of 2 to 10 cm, and more preferably in the range of 3 to 7 cm. By setting the length of the tubular body fixing portion 12 in the longitudinal direction within this range, the fixing force can be improved and the operability of fixing and peeling can be improved.
The length of the tubular body fixing portion 12 in the width direction (see reference numeral L2 in FIG. 1) is preferably in the range of 0.5 to 3 cm, more preferably in the range of 0.8 to 2 cm. .. By setting the length of the tubular body fixing portion 12 in the width direction within this range, the fixing force can be improved and the operability of fixing and peeling can be improved.

The free end side of the tubular body fixing portion 12 that is not connected to the skin fixing portion 11 can be a flat end as in the tubular body fixing tool 1 according to the third embodiment shown in FIG. 4, but is shown in FIG. It is preferable to taper the tubular body fixture 1 according to the first embodiment. By tapering, it becomes the starting point of peeling, so that the operability of peeling from the tubular body or the peeling sheet 2 described later can be improved. The tapered shape is not limited to the shape tapered toward the outside (the side opposite to the tubular body angle adjusting portion 13 described later) as in the tubular body fixture 1 according to the first embodiment shown in FIG. For example, as in the tubular body fixture 1 according to the fourth embodiment shown in FIG. 5, the tubular body fixing tool 1 is tapered toward the tubular body angle adjusting portion 13 side described later, or the tubular body fixing according to the fifth embodiment shown in FIG. It is also possible to taper toward the center as in tool 1.

Regarding the relationship between the tubular body fixing portion 12 and the tubular body angle adjusting portion 13 described later, for example, as in the tubular body fixing tool 1 according to the sixth embodiment shown in FIG. 7, the tubular body fixing portion 12 and the tubular body angle The adjusting portion 13 may have the same length, but the tubular body fixing portion 12 is made shorter than the tubular body angle adjusting portion 13 as in the tubular body fixing tool 1 according to the first embodiment shown in FIG. Is preferable. The tubular body angle adjusting portion 13, which will be described later, is preferably set to a length with a margin in order to adjust the angle of the tubular body, while the tubular body fixing portion 12 has operability of fixing and peeling. From the viewpoint, it is preferable to make the length the minimum necessary.

The form of the first cutout portion C1 is, for example, a semicircular shape, a semi-elliptical shape, a triangle (see the seventh embodiment of FIG. 8), a square, a rectangle (see the eighth embodiment of FIG. 9), or the like. Although it can be formed into a shape or the like, it is preferable to form the tubular body in a shape having a contour formed by a curved line such as a semicircular shape or a semi-elliptical shape from the viewpoint of easy alignment with the outer wall surface.
The position of the first notch C1 in the tubular body fixing portion 12 is 0 from the connecting portion between the skin fixing portion 11 and the tubular body fixing portion 12 when the length of the tubular body fixing portion 12 in the longitudinal direction is 1. The position is preferably 1 to 0.7, and more preferably 0.1 to 0.5. By setting the position to 0.1 or more, it is possible to prevent the wound portion of the tubular body and the skin fixing portion 11 from being too close to each other, and when the tubular body fixing portion 12 is wound around the tubular body or when the tubular body is fixed, the said It is possible to prevent the skin fixing portion 11 from floating. Further, by setting the position to 0.7 or less, a sufficient area for fixing the tubular body to the tubular body fixing portion 12 can be secured.

The connecting portion between the skin fixing portion 11 and the tubular body fixing portion 12 may be formed substantially linearly as in the tubular body fixing tool 1 according to the ninth embodiment shown in FIG. 10, but is shown in FIG. Like the tubular body fixture 1 according to the first embodiment, the second notch portion C2 may be provided. By providing the second notch portion C2, the tension applied to the tubular body fixing portion 12 and the skin fixing portion 11 at the time of winding can be alleviated, and the occurrence of wrinkles and twitching can be prevented, and the appearance is good. The tubular body fixing portion 12 can be smoothly wound around the tubular body. As a result, highly stable fixing becomes possible.
The form of the second cutout portion C2 can be, for example, a semicircular shape, a semi-elliptical shape, a polygonal shape such as a triangle, a square, or a rectangle, but it is easy to fit the tubular body along the outer wall surface. From the viewpoint, it is preferable to form the contour in a curved shape such as a semicircular shape or a semicircular shape.

(3) Tubular body angle adjustment unit 13
The tubular body angle adjusting portion 13 is a portion connected to the skin fixing portion 11 to adjust the angle of the tubular body. Further, the tubular body angle adjusting portion 13 is provided in a state of facing the tubular body fixing portion 12 with a gap thereof. By providing a gap between the tubular body fixing portion 12 and the tubular body angle adjusting portion 13, it is possible to prevent the tubular body angle adjusting portion 13 from interfering with the operation when the tubular body fixing portion 12 is wound around the tubular body. can do.

FIG. 11 is a conceptual diagram showing a method of adjusting the angle of the tubular body by the tubular body angle adjusting unit 13. After the tubular body fixing portion 12 is wound around the tubular body and fixed, the tubular body angle adjusting portion 13 is passed under the tubular body and adjusted to a desired angle so as to support the tubular body from below (see FIG. 11A). Then, the free end side of the tubular body angle adjusting portion 13 that is not connected to the skin fixing portion 11 is overlapped and attached to the skin fixing portion 11 so that the tubular body has a desired angle (see FIG. 11B). ), The angle of the tubular body can be adjusted.

In this technique, the position and angle of the tubular body can be adjusted, so that the tubular body can be fixed at a position and angle that minimizes the burden on the patient. For example, when the tubular body is a nasal catheter, the catheter can be maintained at a position where it does not touch the nostrils or ala of nose, so that the risk of ulcer development can be reduced.
Further, since the tubular body angle adjusting portion 13 is attached on the skin fixing portion 11 so as to intersect and overlap the tubular body fixing portion 12, the tubular body can be fixed more firmly, and the tubular body can be fixed. It also has the effect of preventing the tubular body from being pulled out even if an unexpected pulling force is applied to it.

The form of the tubular body angle adjusting portion 13 is not particularly limited as long as the angle of the tubular body can be adjusted, but from the viewpoint of operability, a strip-shaped form is preferable. The length of the tubular body angle adjusting portion 13 in the longitudinal direction (see reference numeral L3 in FIG. 1, the same applies hereinafter) is preferably in the range of 2 to 10 cm, and more preferably in the range of 3 to 7 cm. By setting the length of the tubular body angle adjusting portion 13 in the longitudinal direction within this range, it is possible to secure a sufficient length necessary for adjusting the angle of the tubular body, improve the fixing force, and further fix or peel off the tubular body. The operability can be improved.
Further, the length of the tubular body angle adjusting portion 13 in the width direction (see reference numeral L4 in FIG. 1) is preferably in the range of 0.5 to 3 cm, and further in the range of 0.8 to 2 cm. preferable. By setting the length of the tubular body angle adjusting portion 13 in the width direction within this range, the fixing force can be improved, and the operability of fixing and peeling can be improved.

The free end side of the tubular body angle adjusting portion 13 that is not connected to the skin fixing portion 11 can be a flat end as in the tubular body fixing tool 1 according to the third embodiment shown in FIG. 4, but FIG. 1 shows. It is preferable to taper the tubular body fixture 1 according to the first embodiment shown. By tapering, it becomes the starting point of peeling, so that the operability of peeling from the tubular body or the peeling sheet 2 described later can be improved. The tapered shape is not limited to the shape tapered toward the outside (the side opposite to the tubular body fixing portion 12) as in the tubular body fixing tool 1 according to the first embodiment shown in FIG. For example, as in the tubular body fixing tool 1 according to the fourth embodiment shown in FIG. 5, the tubular body fixing tool 1 according to the fifth embodiment shown in FIG. 6 may be tapered toward the tubular body fixing portion 12 side. As you can see, it is also possible to taper toward the center.
In each figure, the shapes of the tubular body fixing portion 12 and the tubular body angle adjusting portion 13 on the free end side are substantially left and right with respect to the line of the gap between the tubular body fixing portion 12 and the tubular body angle adjusting portion 13. The symmetric form is illustrated, but it may be asymmetric. For example, the free end side of the tubular body fixing portion 12 may be flattened, and the free end side of the tubular body angle adjusting portion 13 may be tapered.

Regarding the relationship between the tubular body fixing portion 12 and the tubular body angle adjusting portion 13, for example, as in the tubular body fixing tool 1 according to the sixth embodiment shown in FIG. 7, the tubular body fixing portion 12 and the tubular body angle adjusting portion 12 are adjusted. Although the portions 13 may have the same length, the tubular body angle adjusting portion 13 may be longer than the tubular body fixing portion 12 as in the tubular body fixing tool 1 according to the first embodiment shown in FIG. Is preferable. The tubular body fixing portion 12 is preferably set to the minimum necessary length from the viewpoint of operability of fixing and peeling, while the tubular body angle adjusting portion 13 is used to adjust the angle of the tubular body. This is because it is preferable to make the length with a margin.

The connecting portion between the skin fixing portion 11 and the tubular body angle adjusting portion 13 may be formed substantially linearly as in the tubular body fixing tool 1 according to the ninth embodiment shown in FIG. 10, but FIG. 1 shows. A second notch C2 may also be provided, as in the tubular fixture 1 according to the first embodiment shown. By providing the second notch portion C2, when adjusting the angle of the tubular body, the tension applied to the tubular body angle adjusting portion 13 and the skin fixing portion 11 is relaxed, and the occurrence of wrinkles and twitching is prevented. The angle of the tubular body can be adjusted smoothly and visually. As a result, highly stable fixing becomes possible.

The tubular body angle adjusting portion 13 may be provided with a third notch portion C3 on the gap side with the tubular body fixing portion 12, as in the tubular body fixing tool 1 according to the tenth embodiment shown in FIG. Is. By providing the tubular body angle adjusting portion 13 with the third notch portion C3, it is possible to follow the outer wall surface of the tubular body when adjusting the angle of the tubular body, and prevent the occurrence of wrinkles and twitching. The angle of the tubular body can be adjusted smoothly and visually. As a result, highly stable fixing becomes possible.

Further, as in the tubular body fixing tool 1 according to the eleventh embodiment shown in FIG. 13, the tubular body fixing portion 12 and the tubular body angle adjusting portion 13 have the same length in the longitudinal direction, and the tubular body angle adjusting portion has the same length. By providing the third notch C3 in 13, one of the left and right strips is used as the tubular fixing portion 12 and the other strip is used for adjusting the angle of the tubular body, depending on the portion where the tubular body is fixed. It can also be used as a unit 13. That is, when either one is used as the tubular body fixing portion 12, the other can be used as the tubular body angle adjusting portion 13 to fix the tubular body.

On the contrary, since the tubular body angle adjusting portion 13 is not provided with the third notch portion C3, the first notch portion C1 provided only in the tubular body fixing portion 12 serves as a mark, and the tubular body angle adjusting portion 13 serves as a mark. It prevents mistakes such as accidentally wrapping it around a tubular body, and enables highly reproducible fixing regardless of the procedure of the medical staff. Further, even when the tubular body angle adjusting portion 13 is provided with the third notch portion C3, although not shown, the position of the first notch portion C1 of the tubular body fixing portion 12 and the tubular body angle adjusting portion It is also possible to distinguish between the tubular body fixing portion 12 and the tubular body angle adjusting portion 13 by arranging the position of the third notch portion C3 of 13 in a staggered manner.

When the tubular body angle adjusting portion 13 is provided with the third notch portion C3, the form thereof is, for example, a semicircular shape, a semi-elliptical shape, or a triangle (the first notch portion C1 of the seventh embodiment of FIG. 8). It can be in the form of a polygon such as a square, a rectangle (see the form of the first notch C1 in the eighth embodiment of FIG. 9), etc., but along the outer wall surface of the tubular body. From the viewpoint of ease, it is preferable to form the contour in a curved shape such as a semicircle or a semicircle.

When the tubular body angle adjusting portion 13 is provided with the third notch portion C3, the position of the third notch portion C3 in the tubular body angle adjusting portion 13 is set to the length of the tubular body angle adjusting portion 13 in the longitudinal direction by 1. In this case, the position is preferably 0.1 to 0.7 from the connecting portion between the skin fixing portion 11 and the tubular body angle adjusting portion 13, and the position is further set to 0.1 to 0.5. preferable. By setting the position to 0.1 or more, it is possible to prevent the contact portion between the tubular body and the tubular body angle adjusting portion 13 and the skin fixing portion 11 from being too close to each other, and when the tubular body is fixed, the skin fixing portion 11 Can be prevented from floating. Further, by setting the position to 0.7 or less, a sufficient area for adjusting the angle of the tubular body can be secured.

Regarding the positional relationship between the tubular body fixing portion 12 and the tubular body angle adjusting portion 13 described above, the tubular body fixing portion 12 is arranged on the right side of the top view and the tubular body angle adjusting portion 13 is arranged on the left side of the top view in each drawing. However, the present invention is not limited to this, and can be freely changed depending on the site where the tubular body is fixed. For example, although not shown, it is also possible to arrange the tubular body fixing portion 12 on the left side of the top view and the tubular body angle adjusting portion 13 on the right side of the top view.
