Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an instrument for attaching a catheter inserted in a living body to the surface of a living body at a puncture portion and a method for attaching the same.

[0002]

2. Description of the Related Art In many cases, a catheter is used by being punctured mainly from the surface of a living body such as skin into a blood vessel immediately below it and inserted deeply into the blood vessel. In such a case, the catheter is not punctured perpendicularly to the surface of the living body, so that the catheter can be smoothly fed along the running direction of the blood vessel immediately below and in the feeding direction of the catheter. It is punctured with a sharp depression angle to the surface of the living body.

The catheter is subjected to mechanical operation in vitro and administration of a drug into the catheter, which causes a strong force to act on the puncture portion. For this reason, it is necessary to fix the catheter to the surface of the living body around the puncture portion so that external force is not transmitted to the puncture portion and the tip side thereof. At the same time, it is necessary to prevent bacterial infection from the puncture part into the living body. Conventionally, in order to meet such a request, for the puncture portion, an adhesive film dressing is attached to the living body surface so as to cover a wide area including the puncture portion,
A part of the catheter from the puncture part to a desired length outside the living body is laid down along the surface of the living body and fixed, and invasion of bacteria from the outside is prevented.

[0004]

However, as described above, when the catheter is manipulated in vitro, external force in various directions is applied to the puncture portion of the catheter, especially when the catheter is laid down along the surface of the living body and fixed. The external force that tries to cause it repeatedly acts strongly. Further, a multi-functional catheter having a plurality of lumens inside and having various working functions at the distal end has a larger outer diameter and higher rigidity, and has a small amount at the end on the operating side. Even if you apply force
A large force acts on the puncture portion like an action point of a "lever". Therefore, just by pressing the portion from the puncture portion of the catheter to the desired length by the adhesive film dressing as in the past, the adhesive film dressing is easily floated or peeled off by the movement of the catheter, and that portion is not covered by bacteria. There was a problem of becoming an infection route.

The object of the present invention is to attach the catheter along the surface of the living body with good workability even when the catheter is punctured with a sharp depression angle to the surface of the living body, and to fix the catheter to the body. To provide a catheter mounting tool capable of preventing the external force from being transmitted to the puncture portion and maintaining a good protection state of the puncture portion even if a strong external force acts to raise the catheter from the surface of the living body. . Another object of the present invention is to provide a method for preferably fixing a catheter inserted into a living body to the surface of the living body at the insertion portion by using the catheter attachment according to the present invention.

[0026]

The catheter mounting tool of the present invention enables operations including the above (i) and (b) due to the characteristics of its original shape, and the portion from the catheter puncture portion in vitro to a predetermined length (hereinafter, This part of the area can be fixed to the surface of the living body (referred to as "attachment part of catheter"). Among the catheter attachment parts, the part near the puncture part that protrudes from the surface of the living body with a sharp elevation angle can be fixed so as to lie along the surface of the living body, and the force acting on the catheter from the operating side is transmitted to the puncture part. It becomes possible not to.
This operation and action will be described in more detail with reference to the drawings.

FIG. 4 is a diagram schematically showing an example of a state in which the attaching portion of the catheter C is attached and fixed to the living body surface B by the catheter attaching tool of the present invention. In the example of the figure, the shape of the catheter attachment is a rectangle in which the first and second film bases are congruent, and they are laminated so that their outer shapes are the same and are bonded to each other in the region A. The operation of the catheter fitting according to the present invention will be described by dividing the second film substrate into three parts 2a, 2b and 2c. That is, the portion 2a corresponding to the area A, the area 2
One part 2b (a part that is folded over so that the outer surface of the stack is the inner side and covers the catheter) and the other part 2c (a catheter that is laid parallel to the biological surface Part to receive).

In the example of FIG. 4, the first film substrate 1 is
It is attached to the surface of the living body so that the puncture part of the living body is surrounded by the through holes. The catheter obliquely protruding out of the living body from the puncture portion passes through the through hole and protrudes outside the second film substrate 2. Further, the catheter is laid parallel to the surface of the living body and attached to the portions 2a and 2c of the second film base material 2 by an adhesive function. Further, the portion 2b of the second film base material is folded and folded with the boundary line A1 with the portion 2a as a crease so that the outer surface of the stack becomes the inner side,
The portion 2b and the portions 2a and 2c are superposed so as to substantially coincide with each other in a state where the catheter inserted in the through hole is sandwiched, and the portion 2b and the portions 2a and 2c sandwich the catheter, It holds the attachment part of the catheter by the adhesive function.

By overlapping the portion 2b and the portions 2a and 2c, the regions 2b and 2c form one flap F. The flap F has a boundary line between the portion 2a and the portion 2c as an axis, and is capable of opening and closing movement as shown by a thick arrow in the figure by a movement such as turning a page of a book.

When the catheter is attached as described above, the flap F follows the movement even when the external force acts and the catheter C moves in the direction as shown by the thick arrow. As a result, the force to raise the catheter lying parallel to the living body surface on the portion 2a is suppressed, and at the same time, the force to peel off the first film substrate 1 attached to the living body surface is also suppressed. To be done. Therefore, the state in which the catheter is punctured with respect to the surface of the living body is maintained, and the floating and peeling around this are suppressed.

As described above, the catheter attachment of the present invention fixes the catheter by laying it on at least the portion 2a corresponding to the area A parallel to the surface of the living body. However, since the catheter obliquely goes out of the living body from the puncture portion, in actual use, when the catheter that is going out of the living body is laid on the portion 2a in parallel with the living body surface, due to a strong bending at the puncture portion, In order to prevent the catheter from being damaged and the living body from being adversely affected, a gauze or the like may be bitten between the catheter and the living body surface at the puncture portion so that the catheter is relatively gently curved and laid down in parallel. Therefore, the term "parallel" as used herein also includes a substantially parallel state obtained by bending within a range that does not hinder its function.

[0032]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below.
FIG. 1 is a perspective view schematically showing an example of a catheter attachment tool according to the present invention. As illustrated in the figure, the catheter attachment according to the present invention has a first film base material 1 to be attached to the surface of a living body and a second film base material 2 to hold a target catheter laminated. The film bases 1 and 2 are adhered to each other in the area A. Both film bases 1 and 2 have an adhesive function on the outer surface of each laminate. Further, a through hole P having an inner diameter through which a target catheter can be inserted is provided in the region A so as to penetrate the catheter mounting tool in the stacking direction, and the through hole P is divided into a C shape so as to be opened to the outside. A portion Q is provided so as to divide the catheter fitting from the through hole P to the outer shape through the area A.

In the example of FIG. 1, the adhesive function of both film base materials 1 and 2 is provided by providing adhesive layers 3 and 4, respectively, and a separator that covers these adhesive layers 3 and 4 is provided. 5 and 6 are provided. Further, both film base materials 1 and 2 are adhered to each other in the area A by the adhesive layer 7. In FIG. 1, for the sake of explanation, each pressure-sensitive adhesive layer is hatched so that the divided portion Q has a gap. With such a configuration, as described in the above operation, the portion near the puncture portion of the catheter is laid down and fixed so as to be parallel to the living body surface, and the operating side is held movably while being attached to the living body surface. You can

The first film base material to be attached to the surface of a living body is flexible and can be rejected from these because it comes into contact with the surface of the living body, especially human skin through an adhesive function. Those that do not cause a reaction are preferable. Preferred materials include polymers such as acrylic polymers, polyethylene, ethylene-vinyl acetate copolymers, polyurethanes, polyether polyesters, polyether polyamide block copolymers and nylon derivatives. Among them, polymers such as acrylic polymers, polyurethanes, polyether polyesters and polyether polyamide block copolymers have excellent water vapor permeability when processed as a film, and do not impede breathing of the skin, and the skin It is particularly preferable because it is possible to suppress the whitening phenomenon, and because it has transparency, it can be applied while observing the application site. Further, it may be made of only one of the above materials, or may be made by laminating a plurality of films made of any material.

The thickness of the first film base is preferably 10 μm to 75 μm, and more preferably 15 μm, from the viewpoint that it can reduce discomfort when applied to the skin and is excellent in water vapor permeability.
˜45 μm is more preferred.

The second film substrate, which holds the catheter of interest, sandwiches the catheter such that portion 2b is substantially aligned with portion 2a and portion 2c, as described in the preceding section, The areas of attachment 2b, 2c are in close contact with each other to form a flap while holding the attachment part of the catheter by the adhesive function. As a preferable material, other than the same material as the first film base material, polyethylene, a polyolefin film such as polypropylene, a polyester film, a polyvinyl chloride film, and a laminated film of these films and a non-woven fabric, or polyethylene, Porous films such as polypropylene and polytetrafluoroethylene can be used.
Further, this film base material may be made of a single material or may be a laminated film, as in the case of the one film base material.

The thickness of the second film base material is preferably 10 μm to 75 μm, more preferably 15 μm to 45 μm, from the viewpoint of excellent catheter retention.

The outer shapes of the two film base materials are preferably such that the congruent shapes coincide with each other as shown in the example of FIG. 1, but depending on the sticking property to the living body surface, the catheter holding property, etc. The shapes may be changed as appropriate, and the shapes may be different from each other or may be a stack in which congruent shapes do not match. The shape of the first film base material is preferably a rectangle or a square from the viewpoints of easy production and less production loss. However, the radius of these corners is arbitrary. The shape of the second film base is such that the adhesive parts do not substantially stick out when they are folded, and the manufacturing is easy and the manufacturing loss is small. As with the material, rectangular or square shapes are preferred. In particular, a rectangle is a preferable shape in that a sufficient flap area can be secured.

Although the size in such a case is not limited, for example, it is assumed that a human cervical skin is punctured with a catheter having an outer diameter of about 1 mm with a depression angle of 30 to 45 degrees. When using a rectangular film substrate, the outer dimensions of the first film substrate are the long side 5
An example is 0 mm to 250 mm x short side 40 mm to 200 mm, of which long side 75 mm to 160 m.
It is more preferable that m and the short side are 50 mm to 100 mm.
However, in order to match the outer shape with the second film base material, these ranges may be exceeded. The external dimensions of the second film substrate may be the same as the external dimensions of the first film substrate, but can be freely determined according to the intended catheter, such as the area where the catheter should be held. Good.

Any through hole may be used as long as the catheter for the purpose of attachment can pass through it. The cross-sectional shape perpendicular to the axis of the hole and the dimension of the shape are appropriately preferable in view of the shape of the catheter, operability of attachment and the like. You may choose one. Examples of the cross-sectional shape include a circle, an ellipse, a rectangle, a polygon, and a shape in which these are combined.

The area A is set at least for the second film base material. That is, the region A may be similarly set for the first film substrate, but if the region A is preferably set for the second film substrate, the region A is It may be secured at any position on one film substrate.

The area A will be described by assuming that the portion corresponding to the area A set on the second film substrate is the portion 2a as described above and the portions on both sides thereof are 2b and 2c. The width and position of the portion 2a are 2b on both sides sandwiching 2a,
When only one portion 2b of c is folded so that the outer surface of the stack is the inner side, the portion 2b is the portion of the catheter that is inserted into the through hole at the portion where the portions 2a and 2c are combined. It is preferable to set so that they can substantially overlap with each other while sandwiching the mounting portion. That is, in other words, in terms of the length of each part in the vertical direction,
This means that the length of the portion 2b is preferably not less than the sum of the width of the portion 2a and the length of the portion 2c.

The folding line when folding the portion 2b is the portion 2
Setting the boundary line between a and the portion 2b facilitates the folding work and eliminates waste. At this time, if the catheter is a line whose thickness can be ignored, ideally the length of the portion 2b is equal to the sum of the width of the portion 2a and the length of the portion 2c. However, in actuality, the thickness of the catheter cannot be ignored, and in many cases it has an indefinite shape such as including a branch portion. Therefore, in actual use, when the target catheter is sandwiched, the portion 2b becomes So that they can substantially overlap and overlap the combined portion of 2a and portion 2c,
It is preferable that the width and position of the portion 2a be set in consideration of a large amount of deviation due to the thickness of the catheter or the like. As a result, it is possible to minimize the protrusion of the adhesive portion and the like in the flap portion sandwiching the catheter attachment portion, and to make it practically no problem. That is, the term "substantially coincident and overlap" as used herein means not only a perfect coincidence and overlap in a state where catheters having various thicknesses or different shapes are sandwiched, but also to achieve the idea and the purpose of the present invention. It also includes a state of overlapping with a deviation within a permissible range.

Further, as described above, when the first film base material and the second film base material have rectangular outer shapes that are congruent with each other and are laminated so that their outer shapes match each other, the portion 2a is formed. Is preferably provided as a strip-shaped region parallel to the short side of the rectangle.

As described above, it is preferable that the first film base material and the second film base material are overlapped so as to be coincident with each other in the form of a congruent rectangle. It is essential for the second film base material that holds the catheter to have a large and small size. Since the first film substrate is attached to the surface of the living body, it may be designed so as to be attached preferably while including the region A. FIG. 7 is a diagram schematically showing the embodiment based on the embodiment shown in FIG. 1 and further when the dimension of the first film base material in the vertical direction of the rectangular portion is changed to be small. The figure (a) is a plan view seen from the second film substrate side, and the figure (b) is a plan view seen from the first film substrate side. In addition, 1La (changed square portion), 1S, as a symbol indicating the square portion of each film substrate,
2L and 2S are used.

Conventionally commonly used film dressings have an appropriate size such that they are not so small that they are easily peeled off when applied to human skin, and are not excessively large. For example, those having a size of about 100 mm × 120 mm are often used. Therefore, the outer dimensions of the first film base material may be set to this extent. On the other hand, the length of the second film substrate in the longitudinal direction is determined by the width of the region A and the length of the flap determined according to the type of catheter. For example, when the width of the region A is 30 mm and the length of the flap is 50 mm, the length of the second film base material in the longitudinal direction is 160 mm. From these points, FIG.
In addition to the aspect shown in (1), an aspect in which the longitudinal dimension of the portion 1L of the first film substrate is changed to be smaller than the longitudinal dimension of the portion 2L is preferable.
For example, in the embodiment shown in FIG. 1, the length of the second film base material in the longitudinal direction is 160 mm (2L = 80 mm, area A).
Width = 30 mm, 2S = 50 mm), only 1 L of the first film base material is changed from 80 mm to about 40 mm, and the longitudinal length of the first film base material is 120 m.
An example is set to about m.

As a method of adhering the first film base material and the second film base material to each other in the area A, there are adhesive and pressure-sensitive adhesives, welding using heat and ultrasonic waves, and other machines. It is possible to freely select such a structure as a typical joint structure.

The dividing portion makes it possible to open the through hole in a C-shape, and makes it possible to easily apply the catheter attachment tool to a catheter that has already been punctured by a living body. It is a thing. As long as the dividing portion can open the through hole in a C-shape at this portion, it is not only a completely divided portion in advance, but also a fragile portion which is not divided but can be easily divided. It may be a broken line notch and is not particularly limited. The dividing portion may extend from the through hole through the region A to either side of the lateral outline of the catheter fitting. That is, the catheter fitting may be opened in a C shape on either side. For example, when the catheter attachment is applied to a human body, if there is a more preferable positional relationship in the direction in which the catheter is laid down, the side opening in the C-shape, etc., it may be provided on the side corresponding to such purpose.

Further, a mode in which a dividing portion similar to the dividing portion is further provided from the through hole to the outer shape of the catheter fitting through the area A in the direction opposite to the dividing portion is provided. To be By adopting such a mode, the catheter attachment of the present invention can be divided into two pieces at the position of the through hole, and can be completely separated into two pieces,
Catheter mounting work becomes easy. The two pieces may be completely separated from the beginning or may be divided into two pieces for use. Further, by utilizing such an aspect, the opening side in the C-shape may be selected from two alternatives.

The adhesive function imparted to the outer surface of each of the two film base materials is such that the first film base material adheres to the living body surface and the second film base material holds the catheter. To form the flap. The adhesive function is
It is a preferred embodiment that it is provided by providing an adhesive layer on the film substrate.

The pressure-sensitive adhesive layer may be a layer composed only of the pressure-sensitive adhesive or may have a base material in the layer such as a double-sided pressure-sensitive adhesive tape. The pressure-sensitive adhesive is not particularly limited, but it is preferable that the pressure-sensitive adhesive has strong adhesiveness, good adhesion to the skin, and does not cause eczema or the like on the skin. For example, acrylic adhesive,
Examples include rubber-based adhesives, silicone-based adhesives, liquid-absorbing hydrocolloid adhesives, and the like.

As a method of providing the pressure-sensitive adhesive layer on the film substrate, a known method may be used, for example, a method of applying the pressure-sensitive adhesive composition on the film, or a preformed pressure-sensitive adhesive composition. Examples include a method of providing a film on the film. The pressure-sensitive adhesive layer has a thickness of 10 μm to 100 μm, preferably 15 μm to 60 μm. When using a hydrocolloid-based pressure-sensitive adhesive in the pressure-sensitive adhesive layer of the first film substrate, in order to maintain sufficient skin adhesion,
The upper limit of the thickness is preferably about 2 mm.

The adhesive function of both film base materials is preferably covered by a separator which is peeled off before use, as in the example of FIG. The separator protects the adhesive function and further improves the handleability until the catheter fitting of the present invention is used. The base material of the separator is a plastic film (for example,
Examples thereof include polyethylene, polypropylene, polyester and laminated composites thereof, and paper (for example, high-quality paper and kraft paper). Further, the surface of the base material is subjected to a silicone resin treatment, a fluorine resin treatment or the like as a peeling treatment for obtaining good peelability from the pressure-sensitive adhesive layer.

It is preferable that both separators are provided with a cut portion so that they can be partially peeled off, so that the sticking work becomes more efficient and clean. For example, as shown in FIG. 1, the separator 6 on the side of the second film substrate is provided with a cut portion 6A from the through hole in the direction opposite to the cut portion of the catheter fitting and passes through the region A. There is a mode in which it is provided up to the outer shape of the catheter attachment, and this makes it possible to sequentially peel it according to the attaching procedure. The cut part of the separator is not only a completely cut part in advance like the cut part of the catheter fitting, but also a fragile part such as a half cut, etc., which can be easily separated, a broken line such as perforations. It may be a notch and is not particularly limited.

In order to facilitate the peeling of the separator, a trigger for peeling may be formed so that the finger can be easily worn. For example, in the corner portion of the cut portion of the separator, as illustrated in FIG. 7A, the radius of this corner portion is bulged outward to form the trigger portions w1 and w2. In addition, in the straight part of the cut part of the separator, as shown in FIG.
As illustrated in (b), the middle of this straight line is partially bent to form a trigger portion w3. According to these aspects, the separator at the trigger part can be easily peeled off from the adhesive surface and stood up more easily than other parts only by appropriately bending the adhesive surface, and it is also easy to pinch with a finger, which is a preferable trigger at the time of peeling. .

A catheter fitting according to the present invention is shown in FIG.
In the case where the film base materials having the same shape (especially rectangular shape) are matched and overlapped with each other, as shown in, it is preferable that the following structure is further added thereto. That is, as shown in FIG. 2, the first film base material 1 and the second film base material 2 are not only in the area A but also in the portion 2
The outer edge portions 2d and 2e in b and 2c are also bonded to each other. These bonded portions 2d, 2e
Is a structure that can be removed by the cut-to-be-cut portions R and S for the catheter fitting provided along the boundary line between these portions. The glued part 2d,
By removing 2e by the planned cutting portions R and S, mutual adhesion at the outer edge portions of the first film base material and the second film base material is released, and the same as in the embodiment of FIG. .

In addition to this aspect, as shown in FIG.
The separator 5 on the first film substrate side is provided with cut portions 5A and 5B in parallel with the cut portions and on the outside of both cut portions or on the same line as R and S. It is preferable that it can be divided into two parts. The aspect of the cutting portion may be the same as the aspect of the cutting portion of the separator.

As described above, the catheter attachment work is further improved by providing the catheter attachment with the portion to be cut and the separator with the cutting portion. That is,
First, the separated separator 5a is peeled off to expose the adhesive function of the part, and the parts on both sides where the separators 5b and 5c are left are held by both hands, and the exposed adhesive layer is attached to the surface of the living body, and then described later. According to the sticking procedure illustrated in FIG. 3, it is possible to sequentially cut the catheter attachment at the portions to be cut R and S, and discard the portions on both sides that are first held by hand. Therefore, since the part that is touched by the hand is completely removed, the sticking work can be performed easily, quickly, accurately, and more cleanly.

The portion to be cut is like a perforation as long as it can be easily removed from the catheter fitting in the portion where the outer edge portions 2d and 2e that have been adhered to the portion to be cut can be easily removed. Also, it may be a fragile portion that is not cut, and is not particularly limited. FIG. 2 shows a mode of perforations.

Another preferred embodiment of the region of the outer edge, that is, the region for hand-held operation of the catheter fitting as described above is shown. As shown in FIG. 1, when the catheter attachment according to the present invention is a mode in which film base materials having the same shape (especially rectangular) are aligned and overlapped with each other, the outer sides of the square portions on both sides of the area A are sandwiched. It is a preferred embodiment to provide a region that extends further outward from the peripheral edge. The shape of this expanded region is free and will be described later. The first film base material and the second film base material are adhered to each other in one or both of the areas expanded from these rectangular portions (hereinafter, also simply referred to as “expansion areas”). The expansion regions bonded to each other can be removed by the planned cutting portion, and the mutual adhesion at the outer peripheral edge portions of the first film base material and the second film base material can be released. Is the same as.

As an example of the extended area, A rectangular expanded region that is expanded by being in contact with one side in the vertical direction of the rectangular portion (the side far from the region A). The ratio of the length of the outermost side to the length of the side of the rectangular expansion region is arbitrary. When the lengths of one side of both are the same and coincide with each other, the mode is the same as that of FIG. . An expansion region provided in the same manner as above on either or both of the two sides in the lateral direction of the rectangular portion. . Extended area obtained by any combination of the above and. For example, as shown as an extension area 2Le in FIG. 6, a “corner” that is in contact with and surrounds the outer periphery of the rectangular portion on three sides.
The V-shaped expansion region is a particularly preferable example.

Any combination is selected from the above-mentioned modes (1) to (4) and is given to the square portions on both sides of the region A. FIG. 6 is a diagram schematically showing an example of selection of the preferable combination. This figure is a plan view seen from the second film substrate side, and shows an example of dimensions by partially using dimension lines in order to show characteristics of dimension relations. Further, as described above, the rectangular portions of both film base materials are referred to as a portion 1L, a portion 1S, a portion 2L, and a portion 2S. In the figure, part 1
The L and the portion 1S are hidden by being overlapped with the outer shapes of the portion 2L and the portion 2S so as to overlap with each other, and are shown as symbols in parentheses such as 2L (1L).

In the example of the embodiment shown in FIG. 6, the area 2Se expanded from the portion 2S and the area 1S, and the area 1Se are square expanded areas which are one of the above-described embodiments, and the area 2L and the area 1L.
The area 2Le and the area 1Le expanded from are defined as the “U” -shaped expansion areas, which is one of the above-described aspects. Adhesion of the first film base material and the second film base material to each other in the expansion region is performed only in the rectangular expansion regions 2Se and 1Se, and the portions 2L and 1L can be freely opened and closed from the beginning. It was set as the aspect which is. This makes it possible to cleanly perform a series of operations from attaching to the living body surface to removing the expansion region, facilitating the handling of the second film base material for forming the flap, and freely opening and closing each other. The outer peripheral edge portions of the portion 2L and the portion 1L
It can be protected by a "U" shaped expansion area.

As described with reference to FIG. 7, in the mode in which the longitudinal dimension of the portion 1L of the first film base is changed to be small (the changed portion is called the portion 1La),
In the case where an extension region is further provided for each of the portions 1La, 1S, 2L, and 2S, the modes shown in the following (a) and (b) are exemplified as preferable ones.

(A) Similar to the embodiment shown in FIG. 6, as shown in FIG. 7, the areas expanded from the portions 2S and 1S are made into rectangular expanded areas 2Se and 1Se, and expanded from the portions 1La and 2L. The extended area is a U-shaped expansion area 1L
ae and part 2Le. FIG. 7A is a plan view seen from the second film substrate side, and FIG. 7B is a plan view seen from the first film substrate side. An example of the dimension is shown by partially using dimension lines to show the characteristic of the dimension relationship. Since the vertical dimension of the portion 1La has been changed to be smaller than the vertical dimension of the portion 2L, the extension region 1L
Extending the vertical dimension of ae by that amount, expand area 2
It is a preferred embodiment to match the outer shape with Le. As a result, the same characteristics as in the case of the embodiment shown in FIG. 6 can be obtained.

(B) Similar to FIG. 7, rectangular extension regions 2Se and 1Se are provided in the portions 2S and 1S. As for the other rectangular portion, as shown in FIG. 8, the expansion region is provided only in the portion 2L. At this time, the expansion regions of the portion 2L are defined as two rectangular expansion regions 2Le1 and 2Le2 that are in contact with one side of the portion 2L in the vertical direction. Further, a gap larger than the thickness of the catheter is provided between these two rectangular expansion regions 2Le1 and 2Le2. Similar to the other aspects, these expansion regions can be removed by the planned cutting portion. 8A is a plan view seen from the direction of the second film substrate, FIG. 8B is a side view with respect to the view of FIG. 8A, and FIG. 8C is a direction of the first film substrate. It is the top view seen. Further, in the figure, an example of dimensions is shown by partially using dimension lines in order to show the characteristic of dimension relation. According to such a mode, even if the second film base material is bent to hold the catheter and form the flap, the expanded regions do not sandwich the catheter, so that the work of removing the expanded region becomes smoother.

Further, in the case of the mode (b), the separator for protecting the outermost layer of the first film base material is
As shown in FIG. 8 (c), it is preferable to provide a fold line k by perforation or the like in the square portion 1b on the side where the dimension is changed. This makes it easy to peel off the separator at the central portion up to this bending line k and stop the peeling at this line when it is attached to the surface of the living body, as shown in FIG. 9 (a). It is possible to perform a temporary attaching work without holding and to finally peel off the whole.

Furthermore, in the case of the embodiment shown in (b) above, the adhesion of the first film base material and the second film base material in the expanded region is only on the side of the portion 2S (portion 1S). On the side of 2L (part 1La), both the first and second film bases are free ends, and therefore they are flipped up before catheter mounting work, causing contamination or damage. As a preferred example of this solution, as shown in FIG. 8B, a protective film 2n that can be easily and freely peeled off from the surface of the portion 2L and the portion 1La facing each other in the stacking direction. 1n may be used for protection. The material and the forming method (process) of the protective film are not limited, and any material may be used.

Protective film 2n provided on the portion 2L
As shown in FIGS. 8 (a) and 8 (b), is preferably provided so as to cover the two expanded rectangular expansion regions 2Le1 and 2Le2. Further, as shown in FIG. 8, it is preferable that the protective films provided on each of the portion 2L and the portion 1La are adhered to each other on the surfaces facing each other. For the adhesion, a mode in which the pressure-sensitive adhesive layer 3n is interposed is mentioned. By such an aspect, troubles such as the portion 2L and the portion 1La opening and bending before use are suppressed,
It is also possible to increase the rigidity before use. Further, since the protective film 1n on the first film substrate side is inevitably peeled off when the portion 2L is bent to form the flap,
The time and effort of peeling can be saved.

Although the procedure of the operation for attaching the catheter using the catheter attachment of the present invention is arbitrary, an example of a particularly preferable attachment procedure will be described below with reference to FIG. However, it is assumed that the catheter has already been punctured on the surface of the living body at an angle, and the catheter attachment has the configuration shown in FIG. 2 according to the above description. Also, in FIG.
A detailed depiction of the laminated structure appearing on the side of the catheter fitting is omitted.

[0071] Of the separator 5 shown in FIG. 2, only the separator 5a is peeled off to expose the pressure-sensitive adhesive layer, and the portions on both sides where the separators 5b and 5c are left are respectively held by hand, so that the dividing portion Q of the catheter fitting is The through-hole P is divided into C-shaped openings, the catheter C is inserted into the through-hole P, the catheter C is closed based on the through-hole to surround the puncture portion, and as shown in FIG. The first film substrate is attached to the living body surface B so that the portion 2c of the second film substrate is located on the side inclined with respect to the living body surface.

However, the attachment position of the catheter attachment is not limited to the position where the through hole surrounds the puncture portion as shown in FIGS. 3 and 4. For example, as shown in FIG. 10, the catheter protruding from the puncture part is first laid down on the living body surface, the through hole P is arranged at a position apart from the puncture part, and the puncture part is covered with the first film base material. You may attach it. Whatever position the catheter fitting is attached to the puncture, what is common is that the catheter passes through the through-hole and emerges on the second film base material from the area A to the portion 2c. It means that you can lie in the direction.

[0073] As shown in FIG. 3B, the portion on the side of the portion 2c is peeled off by the cutting portion 6A of the separator 6. At this time, it is more preferable to fold the separator without cutting it at the portion to be cut. Further, the catheter C is laid on the portions 2a and 2c and attached to the adhesive surface.

.. As shown in FIG. 3C, the planned cutting portion R on the side of the portion 2b is cut, and the boundary line A1 between the portion 2a and the portion 2b is used as a fold line, and the portion 2b is substantially divided into the portions 2a and 2c. Align and fold and fold and hold the catheter.

[0075] The part S to be cut of the catheter attachment was cut, the part held by hand was discarded, and the first film base material and the second film base material were bonded only in the area A as shown in FIG. With the structure, the catheter attached state shown in FIG. 4 is obtained. At this time, part 2b and part 2c
The overlapped portion is a flap that holds the catheter openable and closable in the direction of the thick arrow with respect to the surface of the living body.

In the case of the embodiment shown in FIGS. 6 and 7, the basic procedure of the operation for attaching the catheter is the same as above. However, due to the "U" -shaped expansion area, the workability of attachment and the removability are different.

When the catheter attachment according to the present invention has a mode in which the through hole is divided into two pieces, the difference from the mode in which the catheter attachment is not divided into two pieces is set so that the catheter is inserted into the through hole. When the work is
The point is whether to open the through-hole into a C shape or to divide it completely.

When the catheter attachment of the embodiment shown in FIG. 8 is used, the procedure of the operation for attaching the catheter is also as follows.
Although it is basically the same as that in FIG. 3, the handling of the extended region and the protective film will be described with reference to FIG. The basic work of attaching the first film substrate to the surface of the living body is shown in FIG.
This is similar to (a) and its description. However, FIG.
As shown in (a), the separator 5 on the side of the first film substrate is peeled off partially by using the bending line k, and it is preferable to peel off the whole after being attached to the surface of the living body. The work up to the formation of the flap holding the catheter is basically the same as in FIG. 3 (a) and its description.
However, as shown in FIG. 9B, a flap is formed so as to cover the catheter so that the catheter exits from the gap j provided between the two rectangular expansion regions 2Le1 and 2Le2. Finally, as shown in FIG. 9C, the protective film (having 1n and 2n adhered to each other) is peeled off, and the expansion regions 2Le1 and 2Le2 are separated from each other by the other expansion region 2
Along with Se and 1Se (which are adhered to each other), they are cut and removed at a planned cutting portion to complete the attachment of the catheter.

If desired, the film substrate, pressure-sensitive adhesive and the like used in the present invention may be mixed with known additives such as antibacterial agents, antiaging agents, stabilizers, fillers, crosslinking agents and pigments. . The catheter fitting of the present invention may be individually packaged in a sterile bag, or may be sterilized by radiation or the like.

The catheter targeted by the catheter attachment of the present invention refers to the entire medical instrument inserted into a living body including a lumen, and also includes an endoscope and a drain.

EXAMPLES The present invention will be specifically described below with reference to examples. In the present example, the workability and the state after the catheter was attached were confirmed by actually producing the catheter attachment according to the present invention and actually applying it to the attachment and fixation of the catheter. The structure in the stacking direction of the catheter attachment manufactured for this example is as shown in FIG. 2, and the respective dimensions in the plane expanding direction are as shown in FIG. FIG. 5 is a plan view of the catheter attachment manufactured for this example as seen from the second film substrate side, in which dimension lines are shown to show the features of the dimensional relationship between the outer shape and the internal region. I am using. The outer shapes of the first film base material and the second film base material are both 100 mm × 120 mm rectangles,
The outer shapes are matched with each other and overlapped. The two shorter sides are the perforated cut portions R and S, and the outer edge portions 2d and 2e having the same width in the long side direction are 20 mm.
Has been extended only. Therefore, as shown in FIG. 5, the entire outer shape is a rectangle of 100 mm × 160 mm. Area A
The first film base material and the second film base material are bonded to each other at the outer edge portions 2d and 2e (that is, the portion 2a). The length of the portion 2a in the vertical direction is 35 mm, and the portion 2b having a length of 60 mm on both sides thereof and the length of 25 m
The part 2c of m is located. A through hole P is provided around the position of the centroid of the portion 2a. The shape of the through hole P has a radius of 7.
It is a kind of oval shape formed by adding a semicircle of 5 mm. Further, a perforated dividing portion Q is provided from the through hole to the outer shape. The outer diameter of the attached catheter was φ2 mm.

The detailed specifications of each layer are as follows. Separator 6; 170 μm thick, high-quality paper treated with silicone. Adhesive layer 4; thickness 20 μm, material acrylic adhesive. Second film substrate 2; thickness 25 μm, material polyether polyester film. Adhesive layer 7; thickness 50 μm, material acrylic adhesive. First film substrate 1; thickness 25 μm, material polyether polyester film. Adhesive layer 3; thickness 20 μm, material acrylic adhesive. Separator 5: 170 μm thick, high-quality paper treated with silicone.

Using the catheter fitting of the above specifications,
The procedure described above was applied to the attachment of an angled and punctured catheter to the skin of the human body. However, the main work procedure is the same as the operation procedure of the above embodiment.
It was confirmed by this example that the catheter was well attached and the catheter could be easily attached. Moreover, when the periphery of the puncture part was confirmed immediately after the attachment, it was found that the puncture part was well sealed and that no interval was formed which would serve as an infection route of bacteria. Further, the attached catheter was moved by various operations from the outside, and a force was applied to the puncture portion in a direction in which the catheter punctured in the living body with a sharp depression angle was raised. However, since the flap portion of the catheter attachment according to the invention follows the movement of the catheter well and the portions 2a and 2b fix the catheter parallel to the surface of the living body, the puncture state is maintained and the first The floating and peeling of the film base material of No. 1 also decreased.

[0084]

According to the present invention, even when the catheter is punctured with a sharp depression angle to the surface of the living body,
The catheter can be attached and fixed along the surface of the living body with good workability. Further, even if a strong external force acts on the catheter to raise the catheter from the surface of the living body, it is possible to prevent the external force from being transmitted to the puncture portion and maintain a good protection state of the puncture portion.
