Description

TECHNICAL FIELD The present invention relates to a bandage and a film for a bandage for covering protruding parts and joint parts of the body.

BACKGROUND ART Examples of wound dressings for covering wounds on the body include household adhesive plasters and medical adhesive plasters called dressings. However, general household adhesive plaster has a shape that is assumed to be applied to a relatively flat body part. There was a problem of getting tired. Therefore, as a fingertip bandage, a complex-shaped bandage that is folded back so as to wrap the entire fingertip (Patent Documents 1 and 2) and a finger sack type bandage that is fitted to the fingertip (Patent Document 3) have been proposed. there is In addition, conventional dressings have high elasticity and are configured to be able to bend and stretch the knees and elbows.

However, in the case of a complicated-shaped adhesive bandage that is folded back and pasted, there is a problem that the pasting method is complicated and time-consuming, and that if the pasting procedure is not followed, water may enter through a small gap. In addition, there is a problem that it is thick because of the large number of overlapping portions, and that the appearance and the feeling of use are bad. Further, in the case of a finger sack type adhesive bandage, there has been a problem that the size does not suit some users.

In addition, when a conventional dressing is used on a protruding part or a joint part of the body, even if the dressing is excellent in stretchability, there is a problem that the skin is stretched. That is, if the dressing material is applied while the knee or elbow is stretched, the skin is pulled every time the knee or elbow is bent and stretched, causing discomfort.

SUMMARY OF THE INVENTION An object of the present invention is to provide a bandage that can be used favorably on protruding parts and joint parts of the body and a film for a bandage that is used therefor.

Another adhesive plaster according to the present invention comprises an adhesive plaster film and a support to which the back surface of the adhesive plaster film is temporarily adhered. When the adhesive bandage film is pressed against the adhesive bandage film from the back side thereof, the adhesive bandage film is plastically deformed in accordance with the shape of the fingertip to enclose the fingertip.

According to the adhesive plaster of the present invention, the film for the adhesive plaster is plastically deformed according to the shape of the protruding part and encloses the protruding part, so that it has good adhesion and prevents water from entering through the gap, and is waterproof. improves. Further, since the adhesive bandage film can be easily adhered to the projecting portion only by pressing the projecting portion against the adhesive bandage film, no complicated procedures are required, and the device is easy to use.

[First Embodiment]
A bandage 1 according to a first embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. The adhesive bandage 1 of the present embodiment is a wound dressing for enclosing protruding parts of the body (for example, fingertips of hands and feet, elbows, knees, heels, shoulders, chins, noses, etc.), and as shown in FIG. A bandage film 2 and a support 3 to which part of the back surface 2a of the bandage film 2 is temporarily adhered. The support 3 is provided with an access space S for accessing the bandage film 2 from the back side, and the back surface 2a of the bandage film 2 is partially exposed through the access space S. In this embodiment, the central opening 3a provided in the support 3 functions as the access space S, and the adhesive bandage film 2 is placed on the surface 3b of the support 3 so as to cover the access space S from the front side with an adhesive layer (not shown). Alternatively, it is temporarily adhered by the self-adhesive property of the film 2 for adhesive bandage.

The bandage film 2 is made of at least a resin, and the bandage film 2 may contain paper and fibers to the extent that the properties of the bandage film are exhibited.

The resin used for the adhesive bandage film 2 can be used without limitation as long as the resin has a residual strain of 30% or more when made into the adhesive bandage film. For example, known resins such as polyurethane-based resins, polyester-based resins, polyvinyl chloride-based resins, polyolefin-based resins, polycarbonate-based resins, polysulfone-based resins, polyphenylene sulfide-based resins, polyimide-based resins, and polyethylene-based resins can be used. , any one of these, or a mixed resin of two or more, may be appropriately selected according to the purpose.

The adhesive bandage film 2 may be a single layer, or may be a laminate of two or more layers of the above known resins. When the adhesive bandage film 2 is composed of two or more layers, the resins to be used may be of the same type or different types, and may be appropriately selected according to the purpose. In addition, one or more particles and/or additives selected from particles such as inorganic particles and organic particles, and additives such as curing agents and coloring agents are added to the resin used in the adhesive bandage film 2. may be added.

The adhesive bandage film 2 has four bulging portions 2c radially outwardly bulging from the central portion, and has a substantially cross shape as a whole when viewed from above. The support 3 is made of polypropylene, for example.

Next, a procedure for applying the bandage 1 will be described. In addition, the case where the business trip part is the fingertip F will be described as an example. Referring to FIG. 2, when the fingertip F is pushed into the adhesive bandage film 2 from the back side of the adhesive bandage 1 through the access space S, the central portion of the adhesive bandage film 2 is temporarily adhered to the support 3 at the periphery. is plastically deformed according to the shape of the fingertip F and wraps around the fingertip F (FIGS. 2(a) and 2(b)). When the fingertip F is pushed further, the peripheral edge of the bandage film 2 is peeled off from the support 3 (Fig. 2(c)). It can be pulled out from the support 3 (FIG. 2(d)).

As described above, the adhesive bandage 1 of the present embodiment has good adhesion and improved waterproofness because the adhesive bandage film 2 is plastically deformed according to the shape of the projecting portion. In addition, since the bandage film 2 adheres to the projecting portion only by pressing the projecting portion against the bandage film 2, the bandage film 2 can be easily pasted without requiring complicated procedures. In addition, since the bandage film 2 is provided with a plurality of bulging portions 2c, even if the peripheral edge portion of the bandage film 2 is applied to the protruding portion, the overlapping portion can be reduced.

If the business site is the elbow or knee, the patch may be applied with the elbow or knee bent. The size of the adhesive bandage film 2 may be appropriately set according to the projecting part to be applied. For example, in the case of a fingertip, as shown in FIG. It is sufficient if the size can include Furthermore, the size of the access space S may be any size that allows the protruding portion to be inserted.

Next, preferred properties of the adhesive bandage film 2 will be described. In the following description, the term “tensile test” refers to a test in which a test piece of 80 mm (length)×20 mm (width) is pulled at a tension speed of 300 mm/min with a distance between chucks of 50 mm using a tensile tester.
The term "elastic hysteresis test" means that a test piece of 80 mm (length) x 20 mm (width) is stretched at a tensile speed of 200 mm/min with a distance between chucks of 50 mm using a tensile tester, and the elongation of the test piece becomes 100%. A test in which the specimen is pulled to the original position for 1 minute and then returned to the original position at a return speed of 200 mm/minute. The term "residual strain" refers to the residual strain of the test piece after the elastic hysteresis test (see FIG. 4).

The thickness of the bandage film 2 is preferably 5 μm to 2000 μm, more preferably 10 μm to 1000 μm, most preferably 15 μm to 500 μm. If the thickness of the adhesive bandage film 2 is within the above range, an excellent fitting feeling (adherence) can be obtained when the projecting portion is enclosed by the adhesive bandage film 2 .

Further, the bandage film 2 preferably has a breaking elongation of 200% or more in all directions. By having a breaking elongation of 200% or more, the adhesive bandage film 2 can reliably enclose the projecting portion without breaking. The elongation at break refers to elongation when a test piece breaks in a tensile test.

Furthermore, the 20% elongation stress (σ20) of the adhesive bandage film 2 is preferably 0.2 N/mm ² to 10.0 N/mm ² , more preferably 1.0 N/mm ² to 10.0 N/mm. ² . If the 20% elongation stress of the bandage film 2 is within the above range, it is possible to suppress the generation of a tight feeling when the bandage film 2 is plastically deformed by the projecting portion. The elongation stress means a value obtained by dividing the test force (load value in tension) in the tensile test by the cross-sectional area of the test piece.

The difference (σ100−σ20) between the 20% elongation stress and the 100% elongation stress (σ100) of the bandage film 2 is preferably −2.0 N/mm ² to 2.0 N/mm ² , and − It is more preferably 1.0 N/mm ² to 1.0 N/mm ² . If the difference between the 20% elongation stress and the 100% elongation stress of the bandage film 2 is within this range, excessive force is not required when the projecting portion is plastically deformed by pressing it against the bandage film 2. It is possible to more reliably suppress the occurrence of a tight feeling when the film 2 for adhesive bandage is plastically deformed.

The breaking strength of the bandage film 2 is preferably 5.0 N/mm ² or more, more preferably 15.0 N/mm ² to 100 N/mm ² . If the breaking strength of the adhesive bandage film 2 is within the above range, the adhesive bandage film 2 can be prevented from tearing when plastically deformed by the projecting portion. The breaking strength is the value obtained by dividing the strength when the test piece breaks in the tensile test (load value under tension) by the cross-sectional area of the test piece.

The moisture permeability of the adhesive bandage film 2 is preferably 500 g/m ² ·24h or more, more preferably 800 g/m ² ·24h or more, as measured by the cup method according to JIS Z0208. If the water vapor permeability of the adhesive bandage film 2 is within the above range, the occurrence of stuffiness can be suppressed even when the film is applied for a long time to a fingertip F that perspires profusely, for example.

The residual strain of the adhesive bandage film 2 is preferably 30% or more in all directions, more preferably 40% or more. If the residual strain of the adhesive bandage film 2 is within this range, the adhesive bandage film 2 is sufficiently plastically deformed in accordance with the shape of the protruding portion, so that the protruding portion can be reliably contained and an excellent fit (adhesion) can be achieved. and prevent excessive tension on the skin.

In addition, the adhesive strength of the adhesive bandage film 2 to SUS at 180° peeling (the adhesive strength of an adhesive layer (not shown) provided on the adhesive bandage film 2 or the adhesive strength of the adhesive bandage film 2 itself) is preferably 0.01N. /20 mm to 20.0 N/20 mm, more preferably 0.1 N/20 mm to 15.0 N/20 mm. The adhesive strength was measured by a method based on JIS Z0237 when a test piece of 110 mm (length) x 20 mm (width) was peeled off at a peel speed of 300 mm/min.

Table 1 in FIG. 3 shows the evaluation results of various characteristics of Examples 1 and 2 of the present invention and Comparative Examples 1 to 3 below. The sensory evaluation in Table 1 was performed by pressing the fingertip of the hand against the adhesive bandage film 2 through the access space S (approximately 3 cm in diameter) of the support 3 and pushing it into the vicinity of the first joint. The fit (adhesiveness) and stuffiness were evaluated by conducting an in-house monitor test (consultation among 10 people). FIG. 4 shows a graph showing the elastic hysteresis test results of Examples 1 and 2 and Comparative Examples 1 to 3, and Table 2 in FIG. 5 shows the residual strain after the elastic hysteresis test. As described above, in the elastic hysteresis test, the test piece is pulled at a tensile speed of 200 mm / min, so the conditions are different from the tensile test in which the test piece is pulled at a tensile speed of 300 mm / min. The elongation stress value of does not necessarily match the elongation stress value measured by the tensile test.

Example 1: A mixed solution of polyurethane resin A having physical properties shown in Table 1, toluene, and methyl ethyl ketone (MEK) at a weight ratio of 91.0:4.45:4.45 was applied to a PET film. It was coated using a bar coater on the release layer of the release PET film laminated with the release layer, dried in an oven at 80 ° C. for 10 minutes, and dried in an oven at 40 ° C. for 3 days. After that, the release PET film was removed together with the release layer to obtain an adhesive bandage film having a thickness of about 40 μm.

Example 2: Polyurethane-based resin A and polyurethane-based resin B having physical properties shown in Table 1, curing agent C having physical properties shown in Table 2, toluene, and methyl ethyl ketone (MEK) were mixed at 70.1:20. A mixed solution blended at a weight ratio of 9:0.104:4.45:4.45 was applied onto the release layer of the release PET film using a bar coater and dried in an oven at 80°C for 10 minutes. After drying for 3 days in an oven at 40° C., the release PET film was removed together with the release layer to obtain an adhesive bandage film having a thickness of about 40 μm.

Next, a modified example of the first embodiment will be described. In addition, in this modified example and the following embodiments as well, the case where the body business part is the fingertip F will be described as an example. Further, in this modified example and the following embodiments, members that are substantially the same as those in the above-described first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

Referring to FIG. 6, in a bandage 1A of this modified example, a support 3' has a circular shape in a plan view, and a handle member 6 for supporting the support 3' is provided. The handle member 6 has a cylindrical shape, and the support 3' is attached so as to cover the top opening (not shown) of the handle member 6. As shown in FIG. In use, for example, the handle member 6 is held with the left hand, the fingertips (F) of the right hand are inserted through the lower opening 6a of the handle member 6 and pushed into the bandage film 2, and the fingertips are pressed in the same manner as described above. should be attached to the By providing the handle member 6 in this manner, the adhesive bandage 1A can be easily gripped, and the adhesive bandage 1A can be easily applied.
[Second embodiment]

Next, a bandage according to a second embodiment of the present invention will be described. Referring to FIG. 7, a bandage 101 of the present embodiment is substantially the same as the bandage 1 of the first embodiment, but differs from the bandage 1 in that a pressing member 5 is further provided.

The pressing member 5 in this embodiment is made of a film material such as a PET film or a polypropylene film having a circular opening 5a in the center and a substantially annular shape in plan view as a whole. to the surface 3b of the support 3 to cover the surface 2b of the bandage film 2. As shown in FIG. The opening 5a has a smaller diameter than the outer diameter of the bandage film 2, and the surface 2b of the bandage film 2 is exposed through the opening 5a. Further, the pressing member 5 is provided with a knob portion 5b projecting radially outward, and the knob portion 5b extends outward from the outer edge of the support 3. As shown in FIG.

A procedure for applying the bandage 101 will be described. Referring to FIG. 8, first, the fingertip F is pushed into the bandage film 2 through the access space S from the back side of the bandage 101, as in the first embodiment described above. Then, the bandage film 2 is plastically deformed according to the shape of the fingertip F and wraps the fingertip F, and the fingertip F thus enclosed by the bandage film 2 protrudes to the front side through the opening 5a of the pressing member 5. (Fig. 8(a)). Next, by grasping the knob 5b, the pressing member 5 is peeled off from the adhesive bandage film 2 and the support 3, and pulled out from the fingertip F (FIG. 8(b)). When the fingertip F is pushed further in this state, the adhesive bandage film 2 is peeled off from the support 3 (Fig. 8(c)). After that, in the same manner as described above, the peripheral portion of the adhesive bandage film 2 is pressed by hand to attach it to the fingertip F, and the fingertip F can be pulled out from the support 3 .

Here, since the adhesive bandage 101 of this embodiment has the pressing member 5, the adhesive force of the adhesive bandage film 2 to the support 3 can be made smaller than that in the first embodiment, and the tightness of the protruding portion of the adhesive bandage film 2 can be reduced. can be reduced. That is, since the stiff feeling at the protruding portion occurs particularly when the protruding portion (fingertip F) is pushed into the bandage film 2 and peeled off from the support 3 at the stage shown in FIG. If the adhesive force to the body 3 is reduced, the stiff feeling can be reduced. However, if the adhesive force is too small, there is a risk that the adhesive bandage film 2 will peel off from the backing 3 before the adhesive bandage film 2 is sufficiently plastically deformed at the stage of FIG. 2(b).

In this regard, in the present embodiment, since the adhesive bandage film 2 is pressed against the support 3 by the pressing member 5, the adhesive bandage film 2 is sufficiently plastically deformed even if the adhesive force to the support 3 is relatively small. It is possible to prevent peeling from the support 3 before it is done. In addition, if the protruding portion (fingertip F) is pushed in with the pressing member 5 removed as shown in FIG. can reduce the occurrence of
[Third embodiment]

Next, a bandage according to a third embodiment of the present invention will be described. Referring to FIG. 9, a bandage 201 of the present embodiment is substantially the same as the bandage 101 described above, but the outer shape of the bandage film 202 is substantially the same as the outer shape of the support 3 . In addition, the bandage film 202 is formed with a perforation line L, and with the perforation line L as a boundary, a film portion 202A corresponding to the bandage film 2 of the first embodiment and the second embodiment, and a peripheral edge surrounding the film portion 202A. Section 202B.

To apply this adhesive plaster 201, as in the second embodiment, the protruding portion (for example, fingertip F) is pushed into the adhesive plaster film 202 through the access space S from the back side of the adhesive plaster 201, and the film portion 202A is pushed into the protruding portion. It is plastically deformed into the shape of Next, the pressing member 5 is peeled off from the bandage film 202 and removed. In this state, when the protruding portion is pushed further, the film portion 202A is separated from the peripheral edge portion 202B along the tear line L and peeled off from the support 3, and the film portion 202A separated from the peripheral edge portion 202B becomes the bandage of the second embodiment. It functions as a film 2 for use. Thereafter, in the same manner as described above, the peripheral portion of the adhesive bandage film 2 (that is, the film portion 202A) may be pressed by hand to adhere to the projecting portion.

The cut line L is preferably formed in a state in which the adhesive bandage film 202 is temporarily adhered to the support 3 in the manufacturing process, and examples of the cut line L include perforations and half-cut lines. Also, a cutting line may be formed instead of the cutting line L, and the adhesive bandage film 202 may be separated in advance into the film portion 202A and the peripheral edge portion 202B.

In this way, by forming the tear line L (or cutting line) in the adhesive bandage film 202 while the adhesive bandage film 202 is temporarily adhered to the support 3, the precision of the adhesive bandage film 2 and the access space S in the manufacturing process can be improved. This eliminates the need for precise alignment and simplifies the manufacturing process.
[Fourth embodiment]

Next, a bandage 301 according to a fourth embodiment of the present invention will be described with reference to FIG. As shown in FIG. 10, a bandage 301 of this embodiment has a bandage film 2 and a protective sheet 7 to which the back surface 2a of the bandage film 2 is temporarily adhered. In order to apply the adhesive bandage 301 to the body, the protective sheet 7 is peeled off and the adhesive bandage film 2 is applied to the body to be applied.

The bandage 301 can be applied to any part of the body, but is preferably applied mainly to joint parts (for example, elbow joints, knee joints, metacarpophalangeal joints, shoulder joints, etc.). For example, when the bandage 301 is applied to the elbow joint, it is applied while the elbow is stretched. If the bandage film 2 is applied while the elbow is stretched in this way, the bandage film 2 will be stretched when the elbow is bent at first, and tension will be applied to the site to be adhered. After the plastic deformation, even if the elbow is bent and stretched, such tension is less likely to be applied, and discomfort is less likely to occur. In addition, since the adhesive bandage 301 can be applied while the joint region such as the elbow is stretched (that is, the region to be applied is kept flat), compared to the case where the joint region is bent and applied, The sticking of the bandage 301 can be facilitated.

In this embodiment, it is preferable that the 20% tensile load value of the adhesive bandage film 2 in the tensile test is 1.5 N/20 mm to 3.0 N/20 mm. By setting the load value at 20% tension to 3.0 N/20 mm or less, it is possible to avoid excessive discomfort (tight feeling) immediately after application to the joint site. Further, by setting the load value at 20% tension to 1.5 N/20 mm or more, the adhesive bandage film 2 can be given sufficient stiffness, and the handleability of the adhesive bandage film 2 can be easily improved. . That is, even if the surface of the adhesive bandage film 2 is not provided with a process film for improving handleability, the adhesive bandage film 2 alone (in a state in which it is removed from the protective sheet 7) does not wrinkle easily, and can be applied to the target site. can be easily

Table 3 in FIG. 11 shows the evaluation results of various characteristics of Example 3 of the present invention and Comparative Examples 1 to 3 described above. Example 3 is the thin film product of Example 1 described above, and is the same as Example 1 except that the thickness of the bandage film 2 is 20 μm. In addition, the sensory evaluation in Table 3 was performed by applying the adhesive bandage film 2 to the elbow joint with the elbow stretched, and evaluating the ease of attachment of the adhesive bandage film 2 to the elbow joint (handling of the adhesive bandage film 2 alone). , resistance to wrinkles), discomfort (tightness) immediately after application, and discomfort (tightness) after repeating bending and stretching of the elbow joint 50 times. bottom.

As described above, the adhesive bandage according to the embodiment of the present invention has been described with reference to the accompanying drawings, but the present invention is not limited to such embodiment, and various modifications and modifications can be made without departing from the scope of the present invention. be.

For example, the shape of the bandage film 2 (and the corresponding shape of the access space S) does not necessarily have to be cross-shaped, and may be circular or polygonal, for example. In the above-described embodiment, the bandage film 2 has four bulging portions 2c, but the bandage film 2 may have any number of bulging portions 2c of one or more. Furthermore, similarly to the modified examples described above, the bandages 101 and 201 of the second and third embodiments may be provided with a handle member 6 .

In each of the above embodiments, the support 3 has a rectangular shape when viewed from above, but the shape of the support 3 does not necessarily have to be rectangular when viewed from above. As shown in Fig. 2, a pair of concave portions 3d having a substantially arc shape in a plan view may be provided on the outer edge.

In each of the above-described embodiments, the access space S has the same shape as the adhesive bandage film 2 (film portion 202A) but with a different size. The access space S and the adhesive bandage film 2 do not necessarily have to have the same shape with different sizes. The access space S does not necessarily have to be an opening 3a with a closed periphery, and may be formed of a notch 3g with a partially open periphery as shown in FIG. When the access space S is configured with such a cutout portion 3g, when removing the support 3 from the projecting portion (fingertip F), the projecting portion can be pulled out laterally in the B direction instead of being pulled out vertically in the A direction. This makes it easier to remove the support 3. Similarly, the opening 5a provided in the pressing member 5 does not necessarily have to be a through-hole with a closed circumference penetrating the pressing member 5 in the thickness direction, but a notch portion with a partially opened circumference. It may be configured by

In the above-described second and third embodiments, the pressing member 5 is made of a film material separate from the support 3, but the pressing member 5 is not limited to this. Alternatively, it may be constructed integrally with the support 3 and folded with respect to the support 3 for use. That is, in the form shown in FIG. 14, one side of one sheet material 30 functions as the support 3, the other side functions as the pressing member 5A, and the pressing member 5A is folded as shown in FIG. 14(a). Then, the pressing member 5A covers the surface 2a of the adhesive bandage film 2. As shown in FIG. Further, the pressing member 5A is provided with an opening 5a, and access to the adhesive bandage film 2 is made possible through this opening 5a.

In use, with the pressing member 5A folded as shown in FIG. 14(a), the projecting portion is pushed into the bandage film 2 and inserted into the opening 5a in the same manner as described above. When the pressing member 5A is opened as shown in FIG. 14(b) and the projecting portion is further pushed in, the bandage film 2 is peeled off from the support 3, so that the peripheral portion of the bandage film 2 is adhered to the projecting portion, and the projecting portion is removed. It can be pulled out from the support 3 .

The adhesive plaster of the present invention can be used not only as a household adhesive plaster but also as a dressing material as a medical wound dressing material, and the adhesive plaster film of the present invention can be used as a dressing material film in addition to the household adhesive plaster film.
