Description

  The present invention relates to a dressing material used for fixing, for example, a catheter or the like and sticking to a wound part.

For the purpose of fixing a catheter used for infusion or the like, protecting a wound part, and the like, dressing materials to be applied to the skin are widely used.
The dressing material generally includes a base material, an adhesive layer formed on one side of the base material, and a release paper that covers the adhesive layer. A thin polyurethane film or the like is used for the base material of such a dressing material because it is flexible and adapts well to the skin after application and hardly causes discomfort.

However, since such a flexible and thin base material has insufficient rigidity, when the release paper is peeled off from the surface (adhesive surface) of the adhesive layer, the adhesive surfaces are bonded together or wrinkled. Easy to handle and poor handling at the time of sticking.
Therefore, a rigid carrier film is peelably laminated on the surface of the base material where the adhesive layer is not formed.

When a dressing material provided with a carrier film is applied to the skin, the carrier film is released from the substrate after the release paper is peeled off and the exposed adhesive surface is attached to the skin.
When applied in such a procedure, since the carrier film is still laminated to the dressing material when applied to the skin, the rigidity of the dressing material is maintained by the carrier film, and there are inconveniences such as adhesion between adhesive surfaces Less likely to occur and excellent handleability when applied.

However, when such a dressing material is applied and the catheter is fixed to the skin, for example, the peeling force when peeling the carrier film from the dressing material is applied to the fixed catheter, which adversely affects the indwelling state of the catheter. There was a thing.
Therefore, recently, a dressing material in which a carrier film has been devised has been proposed as suitable for fixing a catheter (see, for example, Non-Patent Document 1). Specifically, as shown in FIG. 10, the carrier film 24 of the dressing material 20 is divided into two parts, that is, a central portion 24a and a peripheral portion 24b by a dividing line L ′, and the central portion 24a and the peripheral portion 24b. There is a dressing material 20 that can be separated separately.

  When the dressing material 20 is used for fixing the catheter at the time of infusion, first, a caregiver such as a nurse uses the center portion 24a of the carrier film 24 as a base material as shown by an arrow in FIG. Peel from 21. Next, the release paper 23 is peeled, and the dressing material 20 is temporarily placed on the work table so that the exposed surface (adhesive surface 22a) of the adhesive layer 22 faces upward. Next, the catheter is placed in the patient's vein, and an infusion tube is connected to the catheter. Then, while holding the catheter with one hand, the other dressing material 20 is removed from the work table with the other hand. Next, the adhesive surface 22a of the dressing material 20 is attached to the skin from above the catheter. After pasting, the peripheral edge 24 b of the carrier film 24 is peeled off from the base material 21. As a result, only the base material 21 is in close contact with the catheter and the skin via the adhesive layer 22, and the catheter is fixed to the skin.

  In such a method, after the central portion 24a of the carrier film 24 is peeled off in advance, the dressing material 20 is applied from above the catheter. Therefore, only the peripheral edge 24 b of the carrier film 24 is peeled off after the dressing material 20 is applied. Since the dressing material 20 is usually affixed so that the catheter is positioned approximately at the center of the dressing material 20, when the peripheral edge 24b of the carrier film 24 is peeled off, the peeling force at that time is applied to the catheter, Almost no adverse effect on the detention status. Further, when the dressing material 20 is applied, the peripheral edge 24b of the carrier film 24 remains on the dressing material 20 without being peeled off. Therefore, inconveniences such as adhesion between the adhesive surfaces at the time of sticking can be prevented.

However, such a dressing material was not good in handling at the time of sticking.
For example, in the above-described work, when the dressing material once placed on the workbench is picked up again, the dressing material is flat and thin, so it is difficult to get caught by the fingertip and difficult to remove from the workbench. In addition, when the peripheral part of the carrier film is peeled off from the substrate after the dressing material has been applied, it is difficult to grasp the peripheral part of the carrier film and to start peeling. Furthermore, since these operations are performed while wearing gloves, the handling difficulty becomes even more remarkable.
Further, since the carrier film of the dressing material is divided into two parts, a central part and a peripheral part, the number of garbage when the carrier film is discarded becomes two, which is not preferable in terms of waste disposal. It was.

  The present invention has been made in view of the above circumstances, and has an object of providing a dressing material that is excellent in handling at the time of sticking, is preferable from the viewpoint of dust disposal, and is suitably used for fixing a catheter or the like.

The dressing material of the present invention is a dressing material in which an adhesive layer is formed on one surface side of a film base material adapted to the skin, and a carrier film is laminated on the other surface side so as to be peelable from the film base material. Is composed of a central portion which is a continuous region including the center of gravity of the carrier film and is not divided , and a peripheral portion surrounding the central portion, and the central portion and the peripheral portion are at least one place. It is a dressing material that is connected at a non-partitioned portion and is divided at a parting line other than the non-partitioned portion, wherein the parting line has a curved portion, and the curved portion is on the plane of the carrier film, It extends in substantially the entire area of the position opposed to the non-divided portion, when separate the said central portion from the film substrate and the dividing portion as a boundary, the central portion, and the stand of the dressing Wherein the act Te.
In the dressing material of the present invention, a release paper that can be peeled off from the adhesive layer is provided on the side of the adhesive layer opposite to the film substrate, and is further separated on the side of the release paper opposite to the adhesive layer. A mode in which the pressure-sensitive adhesive layer and the pressure-sensitive adhesive layer and release paper that can be peeled are sequentially laminated is also preferable.

  ADVANTAGE OF THE INVENTION According to this invention, it is excellent in the handleability at the time of sticking, is preferable also from the point of a waste disposal, and can provide the dressing material used suitably for fixation of a catheter, etc.

It is sectional drawing which follows an (a) top view which shows an example of the conventional dressing material, and the B-B 'line of (b) and (a).

Hereinafter, the present invention will be described in detail.
FIG. 1 is a plan view showing an example of the dressing material of the present invention, and FIG. 2 is a cross-sectional view taken along the line AA ′ of the dressing material of FIG.
The dressing material 10 </ b> A of this example has a film base material 11 that adapts to the skin, and a release paper 13 is laminated on one surface side thereof with an adhesive layer 12 interposed therebetween. Further, a carrier film 14 is laminated on the other surface side of the film substrate 11 so as to be peelable from the film substrate 11.

The film base 11 is made of a material and thickness that adapts to the skin when applied to the skin. In this example, a polyurethane film having a thickness of 5 to 120 μm is used because it has excellent flexibility and elongation, adapts well to the skin, and has moisture permeability to prevent the affected area from being stuffy. Since the polyurethane film has transparency, the indwelling state of the catheter can be confirmed.
Other materials suitable for the film substrate include polyolefin, polyvinyl chloride, polyamide, ethylene vinyl acetate copolymer, polyester, polyvinyl alcohol, polyvinylidene chloride, and the like. It is about 5-50 micrometers.

The pressure-sensitive adhesive layer 12 formed on the one surface side of the film substrate 11 has a low irritation to the skin and is preferably formed of a pressure-sensitive adhesive having high water resistance.
As the pressure-sensitive adhesive, for example, those mainly composed of acrylic resin, natural rubber, water-based polymer emulsion, thermoplastic rubber, polyurethane, polyacrylic ester copolymer, silicone resin and the like can be used. The material and thickness of the adhesive layer 12 are adjusted so as not to be easily peeled off due to skin perspiration or movement, and to have an adhesive force that does not damage the skin when peeling from the skin. For example, as a preferable specific example, an adhesive layer having a thickness of 10 to 40 μm formed of an acrylic resin such as an acrylic acid copolymer may be used.

  As the release paper 13 laminated on the adhesive surface 12a of the adhesive layer 12, for example, kraft paper treated with silicone resin or non-silicone resin, glassine paper, polyethylene treated with silicone resin or non-silicone resin was laminated. Materials that can be used for medical purposes, such as kraft paper, polyethylene terephthalate (PET) film treated with silicone resin or non-silicone resin, can be appropriately employed.

  In this example, as shown in FIG. 2, the release paper 13 is formed with a larger area than the film base 11 and the adhesive layer 12, and extends outward from the film base 11 and the adhesive layer 12. Is provided. Therefore, it is possible to easily peel the release paper 13 by grasping the extended portion with a fingertip.

On the other surface side of the film substrate 11, a carrier film 14 is provided which is laminated and adhered in a peelable manner to the film substrate 11. By providing the carrier film 14, it is possible to increase the rigidity of the dressing material 10A as a whole and to prevent inconveniences such as adhesion between the adhesive surfaces at the time of application.
Thus, the carrier film 14 is provided in order to improve the handleability of the dressing material 10A, and is peeled off from the film substrate 11 after the dressing material 10A is applied to the skin. Therefore, the peel strength between the film base 11 and the carrier film 14 is not peeled off due to impact or vibration during transportation before application to the skin, and the film base 11 and the carrier film 14 are peeled off by hand. When adjusted, it is adjusted so that it can be easily peeled off.

The peel strength between the film substrate 11 and the carrier film 14 is obtained by appropriately combining the material of the film substrate 11 and the material of the carrier film 14; the contact surface of the film substrate 11 with the carrier film 14 or the carrier It can be adjusted by a method of providing an adhesive layer with controlled peel strength on the contact surface of the film 14 with the film substrate 11.
In this example, polyurethane is used for the film base 11 and paper is used for the carrier film 14. And the peeling strength of the film base material 11 and the carrier film 14 is adjusted by laminating the film base material 11 on the surface of the paper (carrier film 14) processed by chemical treatment such as silicone treatment and clay treatment.

Also, as the material of the carrier film, for example, a resin such as polyethylene is adopted, and the film base material and the carrier film are pseudo-adhered by co-extrusion of polyurethane and polyethylene to produce a laminate that is laminated and adhered in a peelable manner. This can also be used as a dressing material. When polyurethane is used for the film substrate, the material of the carrier film is preferably polyester other than paper, polyolefin such as polyethylene. As the carrier film, a laminate film in which a plurality of films are laminated (for example, a laminate film of a polyester film and another film, etc.) can be used.
Moreover, as a method of adopting the above-mentioned resin as the material of the carrier film and laminating the film substrate and the carrier film so as to be peelable, there are laminating, coating, vapor deposition and the like in addition to coextrusion.

  In this example, as shown in FIG. 2, the carrier film 14 has the same area as the release paper 13 larger than the film substrate 11 and the adhesive layer 12, and extends outward like the release paper 13. It is provided to do. Therefore, after peeling the release paper 13, the dressing material 10 </ b> A can be grasped and stuck to the skin without touching the adhesive layer 12 exposed by peeling of the release paper 13 by gripping the extended portion.

And the carrier film 14 of this example is comprised from two area | regions of the center part 14a and the peripheral part 14b surrounding the perimeter of this center part 14a.
The central portion 14a is formed so as to include at least the center of gravity of the carrier film 14, and the central portion 14a and the peripheral edge portion 14b are connected by one undivided portion P in this example, and other than the undivided portion P, It is divided by the disconnection L. The dividing line L is formed so as to penetrate from one surface of the carrier film 14 to the other surface.

  In this example, the dividing line L is formed from a straight line portion Lα extending from one end portion La of the dividing line L and a curved line portion Lβ other than the straight line portion Lα. In addition, the end portion of the curved portion Lβ that is not connected to the straight portion, that is, the other end portion Lb of the dividing line L is a curved portion Lβ ′ that is curved toward the central portion 14a.

  Thus, about the usage method of 10 A of dressing materials provided with the carrier film 14 with which the center part 14a and the peripheral part 14b were not completely divided | segmented by the one undivided part P, the time of infusion An example of catheter fixation will be described.

  First, as shown in FIG. 3, the center part 14 a of the carrier film 14 is peeled from the film substrate 11, and the center part 14 a is folded outward at the undivided part P. Here, as for the carrier film 14 of this example, the parting line L has the curve part L (beta). Therefore, in peeling off the central portion 14a, the dressing material 10A is bent (warped) by hand so that the carrier film 14 side is on the upper side, thereby contacting the curved portion Lβ of the central portion 14a of the carrier film 14. Any part of the part which is raised naturally lifts off from the film base material 11 and peels off. Therefore, peeling of the central portion 14a can be easily started by grasping this portion.

Next, after the release paper 13 is peeled off, the dressing material 10A is temporarily placed on the work table T or the like so that the exposed adhesive layer 12 faces upward as shown in FIG. When placed in this manner, the folded center portion 14a acts as a stand for the dressing material 10A, and a gap S is formed between the dressing material 10A and the surface of the work table T.
Next, after placing a catheter in the vein of the patient's arm and connecting an infusion tube to the catheter, the fingertip of the other hand is held between the work table T and the dressing material 10A while holding the catheter with one hand. The dressing material 10A is removed from the work table T.
Next, the dressing material 10A is attached to the skin from above the catheter C as shown in FIG. 5 with the adhesive surface 12a of the dressing material 10A facing downward. Thereafter, the center portion 14a of the carrier film 14 is grasped and pulled upward. As a result, the peripheral edge portion 14 b is also lifted, and the entire carrier film 14 is completely peeled off from the film substrate 11.
In this way, only the film substrate 11 can be brought into close contact with the catheter C and the skin via the adhesive layer 12, and the catheter C can be fixed to the skin.

  In such a method, after the central portion 14a of the carrier film 14 is peeled in advance, the dressing material 10A is stuck on the catheter C, and the peripheral portion of the carrier film 14 is peeled off after the dressing material 10A is stuck. 14b only. And since the dressing material 10A is usually stuck so that the catheter C is located at the approximate center of the dressing material 10A as shown in the illustrated example, the peripheral portion 14b of the carrier film 14 is peeled off after the dressing material 10A is stuck. However, the peeling force at that time is applied to the catheter C, and the indwelling state is hardly adversely affected. Moreover, since the peripheral edge part 14b of the carrier film 14 is in a state of being in close contact with the film substrate 11 without being peeled when the dressing material 10A is stuck, the carrier film can be used to prevent adhesion between the adhesive surfaces at the time of sticking. The original effect can also be achieved.

  When the dressing material 10A of this example is placed on the work table T as shown in FIG. 4, the central portion 14a acts as a stand, and there is a gap S between the dressing material 10A and the work table T. It is formed. Therefore, the caregiver can easily pick up the dressing material 10A from the work table T even with one hand wearing gloves with the fingertip inserted into the gap S.

  Furthermore, after applying the dressing material 10A, the center portion 14a of the carrier film 14 remains in the folded state in the dressing material 10A. Therefore, as shown in FIG. 5, the center portion 14 a is grasped and pulled up, and the peripheral portion 14 b of the carrier film 14 can be easily peeled from the film substrate 11.

  Further, in this example, as shown in FIG. 1, the curved portion Lβ of the dividing line L has a curved portion Lβ ′ that is curved toward the central portion 14 a at the end portion Lb of the dividing line L. Therefore, as shown in FIG. 5, when the center portion 14 a of the carrier film 14 is grasped and pulled upward, the pulling force acts from the end portion Lb to the end portion La through the undivided portion P. Troubles such as causing cracks in the undivided portion P can be prevented.

  As described above, the dressing material 10A has a carrier film 14 in which the central portion 14a and the peripheral edge portion 14b are connected by one undivided portion P, and the central portion 14a and the peripheral edge portion 14b are completely divided. Because it has nothing, it is very easy to handle during work. Therefore, even if the caregiver wears gloves and is forced to work with one hand, it can work well.

  Further, the carrier film 14 of the dressing material 10A has a central portion 14a and a peripheral edge portion 14b connected by an undivided portion P, and is not completely divided into two parts. Therefore, only one dust is required when the carrier film 14 is discarded, which is preferable in terms of dust disposal.

  The thickness of the carrier film 14 is determined according to the rigidity required for the dressing material 10A and the material of the carrier film 14, and is preferably in the range of 40 to 250 μm, for example.

In addition, as for the area ratio of the center part 14a and the peripheral part 14b in the carrier film 14, the center part 14a: peripheral part 14b = 1: 0.2-3 are preferable, and 1: 0.7-2.5 are more preferable. If it is such a range, when the dressing material 10A is placed on the work table T, the central portion 14a works well as a stand. Moreover, the peripheral part 14b can be peeled easily by pulling up the center part 14a. Furthermore, inconveniences such as adhesion between the adhesive surfaces at the time of applying the dressing material 10a can be prevented.
The area of the central portion 14a is the area of the part surrounded by the dividing line L and the shortest virtual line connecting the end part La and the end part Lb of the dividing line L, and the area of the peripheral part 14b is The area obtained by subtracting the area of the central portion 14 a from the area of the carrier film 14.

In addition, the number of straight portions Lα and curved portions Lβ in the dividing line L, the ratio of the lengths, and the like can be set as appropriate. As in this example, one straight line portion Lα and one curved line portion Lβ connected to the straight line portion form a dividing line L, and the length ratio of the straight line portion Lα and the curved line portion Lβ is 1: 4 to 20 Within the range, the configuration of the dividing line L is simple, and the above-described effect by providing the curved portion Lβ, that is, the peeling of the central portion 14a is easily started by bending the dressing material 10A. The effect of is sufficiently obtained. Further, as shown in the illustrated example, not only the curved line portion Lβ but also the straight line portion Lα is combined to form the dividing line L, whereby the distance between the end portion La and the end portion Lb (the length of the undivided portion P) is set. It can be adjusted as appropriate. Thereby, the effect that the crack of the non-parting part P which may arise when the center part 14a is pulled up can be prevented more. Moreover, it is easy to adjust the area ratio of the center part 14a and the peripheral part 14b.
The dividing line L may be U-shaped or U-shaped.

The dressing material 10A of this example can be manufactured as follows, for example.
First, the dividing line L is formed on a carrier film 14 made of chemical-treated paper such as silicone treatment or clay treatment by a method such as punching a mold. Next, the film substrate 11 can be peeled on the carrier film 14 while adjusting the peel strength between the carrier film 14 and the film substrate 11 by a method of laminating the film substrate 11 on the surface treated with the medicine. Provided. Next, an adhesive layer forming liquid containing, for example, an adhesive and a water-based or solvent-based solvent is applied to the surface of the film substrate 11 that is not in contact with the carrier film 14 to form an adhesive layer 12, and a release paper is formed thereon. 13 is provided.

  When forming the carrier film and the film substrate by coextrusion, insert the mold from the carrier film side to the depth reaching the interface between the carrier film and the film substrate. By doing so, a parting line can be formed. Thereafter, the adhesive layer and the release paper may be sequentially formed in the same manner as described above.

As the dressing material of the present invention, the form shown in FIG. 6 in which the form of the center part of the carrier film is different from the examples of FIGS.
As shown in FIG. 6, the dressing material 10 </ b> B extends until the center portion 14 a of the carrier film 14 reaches a part Q of the outer edge portion of the carrier film 14. When the central portion 14a is extended so as to reach the outer edge portion in this way, the central portion 14a is peeled off, and when the dressing material 10B is applied from above the catheter C, the extended portion is attached to the extended portion. The state of the catheter C can be visually confirmed better through the corresponding film substrate 11.

  In the case of the example of FIG. 6, for example, when the left and right end portions in the drawing are respectively grasped with the right hand and the left hand, and the dressing material 10B is bent, the central portion 14a of the portion indicated by the arrow is lifted from the film base material 11. Peel off.

  The length of the part Q of the outer edge is preferably a length corresponding to 0.5 to 20% of the entire circumference of the carrier film 14. If it is equal to or greater than the upper limit of the above range, the area of the peripheral edge portion 14b becomes relatively small, so that there is a possibility that the adhesion between the adhesive surfaces at the time of applying the dressing material 10B cannot be sufficiently suppressed. If it is below the lower limit of the above range, there is a possibility that the effect of visually confirming the state of the catheter C through the film substrate 11 may not be sufficiently obtained when the dressing material 10B is applied.

  Examples of the form in which the central portion 14a of the carrier film 14 is extended to a part Q of the outer edge portion of the carrier film include the dressing materials 10C and 10D shown in FIGS. In the case of the example of FIG. 7, for example, when the upper and lower end portions in the drawing are respectively grasped with the right hand and the left hand and the dressing material 10C is bent, the central portion 14a at the position indicated by the arrow is lifted from the film substrate 11 and peeled off. . In the case of the example of FIG. 8, for example, when the left and right end portions in the drawing are respectively grasped with the right hand and the left hand and the dressing material 10D is bent, the central portion 14a at the location indicated by the arrow is lifted from the film substrate 11 and peeled off. .

In the above example, a case where one undivided portion is provided is shown as a preferable example, but a plurality of undivided portions such as two locations may be provided. However, in that case, it is necessary to consider the formation positions of a plurality of undivided parts so that only the center part of the carrier film can be peeled off.
Moreover, there is no restriction | limiting in the shape in planar view of a dressing material.
Further, the dressing material is not limited to the single-wafer type as exemplified above, and a plurality of dressing materials may be continuous and formed in a scroll shape. In that case, it is good also as a release paper unnecessary type by carrying out release coating of the outer surface of a carrier film.

Furthermore, depending on the use of the dressing material, the wound layer, release paper, that is, the adhesive surface of the adhesive layer, may be used to protect wounds, absorb body fluids, maintain a moist environment, promote healing, reduce pain, etc. Depending on the purpose, pad materials such as gauze, non-woven fabric, cotton, sponge, chitin, alginate, silicone rubber, and self-adhesive pad materials (eg polyurethane foam, hydrocolloid, hydrogel, hydropolymer, silicone gel, aqueous gel, etc.) .) May be provided.
In addition to the adhesive, the adhesive layer may contain a component having anti-inflammatory and analgesic action, and may be a poultice type dressing material.

Furthermore, depending on the use of the dressing material, as shown in FIG. 9, the release paper (first release paper) 13 covering the adhesive layer (first adhesive layer) 12 formed on one surface side of the film substrate 11 is used. An adhesive layer (second adhesive layer) 12 ′ and a release paper (second release paper) 13 ′ may be sequentially laminated on the outer surface side (the side opposite to the adhesive layer 12). The release paper 13 and the adhesive layer 12 ′ are formed so as not to be peeled, and the release paper 13 ′ and the adhesive layer 12 ′ and the release paper 13 and the adhesive layer 12 are formed so as to be peelable.
As described above, the release paper 13 is provided on the side of the adhesive layer 12 opposite to the film substrate 11, and the adhesive layer 12 ′ is further released on the side of the release paper 13 opposite to the adhesive layer 12 described above. The dressing material 10A ′ in a form in which the paper 13 ′ is sequentially laminated is superior in terms of workability and hygiene when the dressing material 10A ′ is used for fixing a catheter, for example.

That is, when using the dressing material 10A ′ of this example, first, the outermost release paper 13 ′ is peeled off, the adhesive layer 12 ′ covered with the release paper 13 ′ is exposed, and the caregiver's The dressing material 10A ′ is attached to a hygienic place such as a hand glove (hereinafter simply referred to as a caregiver's glove) holding the catheter. Thereby, temporary placement (temporary adhesion) can be performed so that the dressing material 10A ′ does not fall. Next, in the dressing material 10A ′ temporarily placed as described above, the central portion 14a of the carrier film 14 is peeled off from the film base material 11, and the central portion 14a is folded outward at the undivided portion P. Next, the caregiver places the catheter in the patient's vein, connects an infusion tube to the catheter, and then holds the catheter with one hand while holding the temporary dressing fixed to the caregiver's gloves. The material 10A 'is taken up from the caregiver's gloves with the other hand. At this time, since the adhesive layer 12 ′ is adhered to the caregiver's gloves, the release paper 13 and the adhesive layer 12 are separated. Next, the adhesive surface 12a of the adhesive layer 12 newly exposed by this peeling is attached to the patient's skin from above the catheter. Then, by grasping the center portion 14 a of the carrier film 14 and pulling it upward and peeling the entire carrier film 14, only the film substrate 11 can be brought into close contact with the catheter and the skin via the adhesive layer 12.
As described above, according to the dressing material 10A ′ in the example of FIG. 9, it can be temporarily placed in a hygienic place such as a caregiver's gloves, and the fall during the temporary placement is suppressed, so that the workability is excellent. In addition, from the dressing material 10A ′ in a state of being adhered to a caregiver's gloves, the operation of exposing the adhesive layer 12 can be easily performed with one hand. In addition, the adhesive layer 12 ′ that adheres to the caregiver's gloves during temporary placement and the adhesive layer 12 that adheres to the patient's skin are separate layers, and the adhesive layer 12 is sealed with a release paper 13 until immediately before application. Therefore, it is possible to avoid the problem of hygiene that resident bacteria, airborne bacteria, dust, dust, etc. in the facility migrate to the patient's skin through the adhesive layer, which is hygienic.
