Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency bandage, and more particularly to an emergency bandage that reduces external impact and has a high hemostatic action.

[0002]

2. Description of the Related Art In general, an emergency bandage has a structure in which an adhesive layer is provided on one side of a base sheet made of a soft film, and a gauze is adhered to the center of the adhesive layer. It is used by sticking to the affected area. However,
Since the thickness of the base sheet is relatively thin in a normal first-aid bandage, severe pain may occur when an object or the like comes into contact with a portion corresponding to an affected part of the first-aid bandage for some reason.

Therefore, Japanese Patent Application Laid-Open No. Hei 10-118174 discloses that linear low-density polyethylene is 60 to 80% by weight,
It is composed of 40 to 20% by weight of an ethylene-vinyl acetate copolymer, has an expansion ratio of 12 to 17, and a thickness of 0.7 to 1.3 mm.
Emergency plasters based on ionizing radiation-crosslinked polyethylene foam sheets have been proposed, and Japanese Utility Model Laid-Open No. 4-108520 has an absorbent pad in which a soft foam is wrapped with gauze or the like. First aid bandages have been proposed.

[0004]

However, the first-aid bandage disclosed in Japanese Patent Application Laid-Open No. 10-118174 is intended to provide buffering only to a base sheet having a smaller thickness than a pad or the like. There is a limit to the improvement of the buffer function as a whole. In addition, since the amount of the linear low-density polyethylene is adjusted so as not to compress the affected part, the hemostatic effect is poor. Furthermore, the manufacturing process of the base sheet portion becomes complicated, and there is a problem in manufacturing efficiency and cost.

On the other hand, the first-aid bandage described in Japanese Utility Model Laid-Open No. 4-108520 can provide cushioning to the pad portion. However, the periphery of the soft foam is almost completely surrounded by gauze or the like. The degree of freedom of deformation is small. Therefore, it is difficult for the soft foam to exhibit a high cushioning effect when an impact force is actually applied. Further, since the flexible foam is adhered to the base sheet via the gauze or the like, the flexible foam may fall off from the gauze or the like during use. Further, the thickness of the gauze or the like increases the thickness of the entire absorbent pad, which makes it difficult to use. It should be noted that Japanese Utility Model Laid-Open No. 4-108520 does not disclose the necessity of early hemostasis in an affected part (for example, a wound).

[0006] It is an object of the present invention to solve the above-mentioned problems in the prior art. That is, a first object of the present invention is to provide an emergency bandage which has a higher cushioning property than the conventional one and does not give a shock of contact with the outside world to an affected part. Further, a second object of the present invention is to have a thin shape despite having a high cushioning property, and
It is to provide an easy-to-use first aid bandage. A third object of the present invention is to provide a novel emergency bandage having a higher hemostatic action than the conventional one.

[0007]

According to the present invention, there is provided a base sheet, a flat pad contacting an affected part (including a wound), and
This is an emergency bandage including an elastically deformable cushion material. The first-aid bandage may have a layer structure in which the pad is adhered to one surface of the base sheet, and the cushion material is adhered to the other surface of the base sheet. The material may have a layered structure located between the pad and the base sheet. Also,
The first-aid bandage of the present invention is a first-aid bandage including a plurality of base sheets, a flat pad in contact with an affected area (including a wound), and an elastically deformable cushion material. It may be an emergency plaster characterized by being located between base sheets.

[0008] The cushion material used in the present invention is a bag-like material in which gas is sealed by a deformable thin film,
Alternatively, it is preferable to use a hollow spherical body having a diameter of 0.1 to 5 mm, but a foam may be used if it is used in a state where it can be freely deformed. The maximum thickness of the cushion material is preferably 0.1 to 5 mm. The base sheet in the present invention is preferably a foam sheet.

[0009]

FIG. 1 is a view showing an example of an embodiment of an emergency bandage according to the present invention. FIG. 1 (a) is a top view and FIG.
(b) is a sectional view. In the embodiment shown in FIG. 1, an adhesive layer 2 is laminated on one surface 1 a of a base sheet 1, and a diseased part (including a wound) is substantially at the center of the adhesive surface 2 a of the adhesive layer 2. A flat pad 3 that comes into contact with is attached. The adhesive surface 2a is protected by the release paper 4, and the release paper 4 is peeled off from the adhesive surface 2a in use.

The material of the base sheet 1 is not particularly limited. For example, a polyvinyl chloride resin, a polyurethane resin, a polyethylene resin, a polypropylene resin, an EVA resin, a polyacryl resin, etc. And a woven or nonwoven fabric made of a material such as a synthetic resin film or sheet, a polyurethane, a styrene-isoprene-styrene copolymer, or a styrene-ethylene-butylene-styrene copolymer. The base sheet 1 may be a single-layer sheet or a laminated sheet made of sheets, films, woven fabrics or non-woven fabrics of the same or different materials. The thickness of the base sheet 1 is preferably in the range of 0.1 to 2 mm, and more preferably in the range of 0.3 to 1.5 mm. If the thickness is less than 0.1 mm, the strength of the base sheet 1 is reduced, and its production is difficult. On the other hand, if it exceeds 2 mm, the flexibility of the base material sheet 1 is reduced, giving an uncomfortable feeling when used.

As necessary, a foaming agent, an ultraviolet absorber, a stabilizer, a filler, a lubricant, an antistatic agent, a coloring agent, and the like may be added to the material constituting the base sheet 1. In order to improve flexibility and cushioning property, a foaming agent is preferably added. In such a case, the foamed base sheet 1 is foamed and crosslinked by extrusion foaming or the like. Examples of the foaming agent include azodicarbonamide, hydrazodicarbonamide, azodicarboxylic acid amide, and dinitrosopentaethylenetetramine. Further, as the filler or coloring agent, for example, titanium oxide, zinc white, lead white, lithobon, graphite, cobalt yellow, molybdenum red, red bengala, lead red, ultramarine,
Cobalt green, chrome green, carbon black, calcium carbonate, barium sulfate, aluminum hydroxide, lake red C, benzidine yellow and the like.

When the base sheet 1 is made of a synthetic resin film or sheet, a plurality of fine holes may be formed in order to improve air permeability. Further, for the purpose of, for example, eliminating the feeling of discomfort when used by being wound around a finger, the base sheet 1 may be embossed to improve the slipperiness of the surface.

Examples of the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 2 include an acrylic pressure-sensitive adhesive, a rubber-based pressure-sensitive adhesive, a silicone-based pressure-sensitive adhesive, a polyurethane-based pressure-sensitive adhesive, and a water-soluble polymer-based pressure-sensitive adhesive. However, silicone-acrylic pressure-sensitive adhesives are preferred in terms of water resistance, waterproofness, and low irritation to the skin. Examples of the acrylic pressure-sensitive adhesive include homo- or copolymers of acrylate-based monomers such as butyl acrylate, isononyl acrylate, 2-ethylhexyl acrylate, and 2-hydroxyethyl acrylate, or these monomers and vinyl acetate or acrylic acid. And copolymers with other monomers. Examples of the rubber-based pressure-sensitive adhesive include a rubber base material such as a synthetic polyisoprene rubber, a styrene-isoprene-styrene block copolymer, and a natural rubber compounded with a tackifier resin, a softener, and the like. The form of the pressure-sensitive adhesive is not particularly limited, and any type of pressure-sensitive adhesive such as a solvent-based, emulsion-based, hot-melt-based, or dry blend-based adhesive can be employed. Adhesive layer 2
Is preferably smaller than the thickness of the substrate sheet 1,
Specifically, it is appropriately adjusted in the range of 0.01 to 2 mm according to the thickness of the base sheet 1.

In the present invention, as the pad 3, a substantially flat sheet-shaped and liquid-absorbing pad is used. Specifically, the pad 3 is made of gauze, cotton cloth, non-woven fabric, a composite of absorbent cotton and non-woven fabric, and absorbent cotton. A net, a composite product of a nonwoven fabric and a net, or the like is appropriately used. Further, it is preferable that the pad 3 is sterilized by disinfecting the pad 3 in advance, or sterilized after being combined with the base sheet 1 or the like to form an emergency bandage. In the present invention, since a flat pad is used as the pad 3, the thickness of the first-aid bandage can be reduced.

Examples of the release paper 4 include paper base materials such as high-quality paper, medium-quality paper, glassine paper, etc., which have been subjected to a silicone release treatment.
Examples thereof include a polyester film such as polyethylene terephthalate, a polyethylene film, and a polypropylene film. If the adhesive layer 2 and the pad 3 are protected from the outside and can be easily peeled off from the adhesive surface 2a, the material is as follows. There is no particular limitation.

In the embodiment shown in FIG. 1, a cushion having substantially the same size as the pad 3 is provided substantially at the center of the surface 1 b of the base sheet 1 opposite to the surface 1 a facing the adhesive layer 2. One material 5 is attached via an adhesive layer 6. Since the cushion material 5 in the present invention can be elastically deformed, when an impact from the outside is applied, the entire cushion material 5 or at least a part thereof is deformed. Therefore, the impact force from the outside is absorbed or reduced by the cushion material 5 and is not directly transmitted to the affected part. Further, the cushion material 5 has a high buffering function because its deformation is not hindered by the pad 3. And since the cushion material 5 is directly fixed to the base material sheet 1, it does not fall off from the first aid bandage at the time of use.

In the present invention, the structure and material of the cushion member 5 are not particularly limited as long as the cushion member 5 can be elastically deformed. In the embodiment of FIG. Are sealed in a bag having a substantially square cross section. The first-aid bandage using such a cushioning material can apply pressure from the gas sealed in the cushioning material 5 to the pad 3.
Has a high hemostatic effect.

In the present embodiment, the “deformable thin film” constituting the cushion material 5 means a deformable film or sheet, and the material is not particularly limited as long as it has airtightness. Although not preferably, polyethylene, polypropylene, polystyrene, polyvinyl chloride, acrylic resin, polyamide, polyester, polyvinylidene chloride, polyacetal, thermoplastic elastomer, various synthetic resins such as synthetic rubber, natural rubber and the like Natural materials or metal foils are used. The thin film may be a single layer or may be composed of a plurality of layers having different properties. In addition, from the viewpoint of the cushioning property of the cushion material 5, it is preferable that the thin film itself can be elastically deformed.

The thickness of the thin film is not particularly limited as long as the cushion material 5 can accommodate a sufficient amount of gas for obtaining a cushioning effect. However, the thickness of the cushion material 5 and the feeling of use as an entire first aid bandage are considered. From the perspective of 0.001-2m
m is preferable. When the thickness of the thin film is less than 0.001 mm or less, the strength of the cushion material 5 becomes insufficient. On the other hand, when the thickness exceeds 2 mm, the degree of deformation of the cushion material 5 decreases and the cushioning effect decreases. In addition, the edge of the thin film is bonded to the cushion material 5 by heat sealing or an adhesive, for example.

As the gas to be sealed inside the cushion material 5, air or other gas can be used, but the type is not particularly limited. In order to provide a high hemostatic effect, the gas is preferably sealed in the cushion material 5 with a pressure higher than the external pressure. However, the gas is absorbed to a level at which impact from the outside does not cause pain to the affected part,
Further, as long as a desired hemostatic effect can be obtained, the pressure for filling the gas may be equal to or lower than the external pressure. In addition, since the pressure of the gas in the cushion material 5 may decrease due to long-term use, it is preferable that a small amount of a liquid that can be vaporized at room temperature is sealed in the cushion material 5.

In the embodiment shown in FIG. 1, the size of the cushion material 5 is substantially the same as that of the pad 3, and
Although arranged at a position corresponding to the pad 3, the size and arrangement of the cushioning material in the present invention are not particularly limited, as long as high cushioning properties and hemostatic action can be imparted as a whole of the bandage. For example, the size of the cushion material 5 may be smaller than the pad 3, and the location of the cushion material 5 may not be a position facing the pad 3. However,
If the volume of the cushioning material 5 becomes excessively large, it becomes difficult to package the entire first-aid bandage, and it becomes difficult to use. Therefore, the maximum thickness of the cushioning material 5 in the cross-sectional direction is 0.1 to 5 mm, preferably. Is set in the range of 0.1 to 3 mm, more preferably 0.1 to 2 mm.
If the maximum thickness is less than 0.1 mm, it is difficult to obtain a sufficient cushioning effect by the cushion material 5, while 2 m
If m is exceeded, the thickness of the entire bandage will increase, giving an uncomfortable feeling during use, and packaging of the bandage itself will be difficult.

The adhesive layer 6 can be made of the same material as the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 2, but in addition, a curable adhesive such as an epoxy resin may be used. Can be. In addition, the thickness of the adhesive layer 6 is specifically adjusted appropriately in the range of 0.001 to 1 mm.

The emergency bandage shown in FIG. 1 is manufactured, for example, as follows. That is, first, an adhesive is applied to one surface 1 a of the base sheet 1 to form the adhesive layer 2. Next, the pad 3 is placed at a substantially central portion of the adhesive surface 2 a of the adhesive layer 2, and the entire adhesive surface 2 a is covered with a release paper 4. On the other hand, an adhesive is applied to a substantially central portion of the other surface 1b of the base sheet 1a to form an adhesive layer 6, on which a bag-like cushion material 5 in which gas has been sealed in advance is placed and fixed.
Note that an adhesive may be applied to a part of the cushion material 5 in advance to form the adhesive layer 6, and the adhesive surface may be adhered to the base sheet 1 and fixed. Lastly, the base sheet 1 is punched out to form an emergency plaster of various shapes.

FIG. 2 is a cross-sectional view showing another embodiment of the emergency bandage of the present invention. Here, the same members as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted. Illustration of the release paper is omitted. The embodiment shown in FIG. 2 differs from the embodiment shown in FIG. 1 in that the cushion material 5 is provided between the pad 3 and the base sheet 1.
As described above, when the cushion member 5 is directly attached to the pad 3, the compressive force generated by the gas pressure in the cushion member 5 is directly transmitted to the affected part, so that the hemostatic effect is further increased. Further, since the impact force from the outside is transmitted to the cushion material 5 through the base material sheet 1 and the adhesive layer 2, the magnitude of the impact force to be absorbed or reduced by the cushion material 5 is reduced. Therefore, the cushion member 5 can more reliably prevent transmission of an impact force from the outside to the affected part. In the embodiment shown in FIG. 2, it is particularly preferable that the base material sheet 1 is a foamed sheet, since the load on the cushion material 5 is further reduced. Further, the base sheet 1 does not need to be completely flat, and a part thereof may form a curved surface.

The emergency bandage shown in FIG. 2 is manufactured, for example, as follows. That is, first, an adhesive is applied to one surface 1 a of the base sheet 1 to form the adhesive layer 2. Next, the cushion material 5 is fixed to a substantially central portion of the adhesive surface 2 a of the adhesive layer 2, and an adhesive is further applied to a part of the cushion material 5 to form the adhesive layer 6. Then, the pad 3 is placed and fixed on the adhesive layer 6, and the entire adhesive surface 2a is covered with a release paper (not shown). In addition, cushion material 5
The adhesive layer 6 may be formed by applying an adhesive to a part of the adhesive layer. Finally, the adhesive tape to which the cushioning material 5 and the pad 3 are adhered in this way is punched out to obtain an emergency plaster of various shapes.

FIG. 3 is a sectional view showing still another embodiment of the emergency bandage of the present invention. Here, the same members as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted. Illustration of the release paper is omitted. In the embodiment shown in FIG. 3, the entire first-aid bandage is composed of two base sheets 1, 1 '.
The embodiment is different from the embodiment shown in FIGS. 1 and 2 in that a cushion material 5 is located between the two base sheets 1 and 1 ′. As described above, when the cushion material 5 is attached between the base sheets 1 and 1 ', the cushion material 5
Can be safely used for a long time without dropping off from the base sheet 1 for some reason. Further, since a part of the impact force from the outside is absorbed by the plurality of base sheets 1, 1 ′ and the pressure-sensitive adhesive layer 2, the impact force from the outside to the affected part is combined with the absorption and cushioning action by the cushion material 5. Can be more reliably prevented from being transmitted. In the embodiment shown in FIG. 3, it is particularly preferable that the base material sheets 1 and 1 ′ are foam sheets, since the burden on the cushion material 5 is further reduced. The base sheets 1 and 1 'do not need to be made of the same material, but may be made of different materials.

The emergency bandage shown in FIG. 3 is manufactured, for example, as follows. That is, first, an adhesive is applied to one surface 1a of the base sheet 1 to form an adhesive layer 2, thereby obtaining a first adhesive sheet. Similarly, an adhesive is applied to one surface 1'a of the base sheet 1 'to form an adhesive layer 2' to form a second adhesive sheet. Next, the pad 3 is fixed to a substantially central part of the adhesive surface 2a of the adhesive layer 2 of the first adhesive sheet, and the entire adhesive surface 2a is covered with a release paper (not shown). On the other hand, a cushion material 5 is placed and fixed substantially at the center of the adhesive surface 2'a of the adhesive layer 2 'of the second adhesive sheet. Lastly, the adhesive surface 2'a of the second adhesive sheet is stuck on the first adhesive sheet, and thereafter, the first and second adhesive tapes are punched into the same shape to obtain an emergency bandage.

FIG. 4 is an enlarged top view and a side view showing an example of a cushion material usable in the present invention. FIG. 4 (a) shows a single cushion material shown in the embodiment shown in FIG. FIG. 4 (b) shows a cushion material 5a made of a bag-like material.
Is a cushion material 5b composed of an aggregate of a plurality of hollow spherical bodies 7
Is shown. As is clear from the figure, since the cushion material 5a in FIG. 4 (a) seals the gas with a deformable thin film, the volume of the space in which the gas can move is relatively large. High degree of freedom of deformation. Therefore,
The cushion material 5a has a large deformation force and has a high cushioning property against an external impact. In addition, since the thin film forms a uniform surface, it is possible to effectively use the compressive force provided by the gas inside, and the hemostatic effect is high.

On the other hand, the cushion material 5 shown in FIG.
As shown in the figure, b is an aggregate of hollow spherical bodies 7 formed from elastically deformable spherical shells, and a gas is sealed inside the hollow spherical bodies 7. Therefore, in addition to the buffer effect by the gas, it is possible to use the buffer effect by the elastic force of the spherical shell itself, thereby having a high buffering property against an impact force from the outside. In addition, since the volume occupied by the gas in each hollow spherical body 7 is relatively small, the rate of expansion and contraction of the gas due to a change in the outside air temperature is small, so that a stable buffering effect can be obtained. The diameter of the hollow spherical body 7 is usually 0.1 mm.
It is appropriately set in the range of 1 to 5 mm, but is 0.1 to 3 mm
Is more preferable, and the range of 0.1 to 2 mm is more preferable. If the diameter of the hollow spherical body 7 is less than 0.1 mm,
Insufficient buffering effect by gas, on the other hand, when it exceeds 5 mm, the overall thickness of the first-aid bandage increases, giving a sense of incongruity,
Also, its packaging becomes difficult. A plurality of hollow spheres 7 are connected to each other by a suitable binder such as a hot-melt adhesive to form a cushion material 5b.

In the present invention, the cushion material 5
May be constituted by a foam. As the material of the foam, polystyrene, AS, ABS, polyethylene, polypropylene, polyvinyl chloride, polyvinyl alcohol, polyamide, polyurethane, phenol resin,
Known resins such as urea resin, epoxy resin, acrylic resin, silicone, pyranyl resin, polyisocyanurate, polyimide, acetylcellulose, viscose and the like can be used alone or in combination of two or more.

[0031]

The present invention will be described below in detail with reference to examples and test examples. However, it goes without saying that the invention is not limited only to these examples.

Example: As an example, an emergency bandage having the structure of FIG. 3 was manufactured as follows. That is, first, a silicone-acrylic pressure-sensitive adhesive was applied to one surface of each of two base sheets made of a urethane nonwoven fabric, and a pressure-sensitive adhesive layer was formed to produce first and second pressure-sensitive adhesive tapes. . Next, a pad was attached to a substantially central portion of the adhesive surface of the first adhesive tape, and the adhesive surface was covered with a release paper. On the other hand, a hollow cushion obtained by heat-sealing the open end of a polyethylene bag was placed and fixed substantially at the center of the adhesive surface of the second adhesive sheet. Finally, the first and second pressure-sensitive adhesive sheets were stuck together so as to sandwich the hollow cushion, and punched into a rounded rectangular shape at both ends to produce an emergency bandage.

Comparative Example: As a comparative example, an emergency bandage was produced in the same manner as in the example except that the hollow cushion was not used. Note that a vinyl chloride film and a rubber-based pressure-sensitive adhesive were used as the materials of the base sheet and the pressure-sensitive adhesive layer, respectively.

The following tests were performed on the emergency bandages thus obtained in Examples and Comparative Examples. Hemostasis test: Farmakol Toksikol, 52 , 4.48-52 (1989)
A hemostatic test was performed according to (РЕЗНИКОВ КМ). That is, a comparative example in which the back skin of a male Wistar rat (7 W) was punched out at two places using a punch having a diameter of 5 mm, and the first-aid remedy was measured in one hole in advance and the other was measured in the other hole in advance. The first-aid bandages were applied by peeling off the release paper. Ten minutes later, both emergency bandages were peeled off, the weight of each bandage was measured, and the weight of attached blood was calculated according to the following formula. Adhesive blood weight = Adhesive band weight 10 minutes after application-Adhesive band weight before application This test was performed three times to compare the hemostatic effect. Table 1 shows the results.

[Table 1]

Buffering test: Emergency adhesive plasters of Examples and Comparative Examples were peeled off and pasted on a phenolic resin plate.
The stress when the approximate center of each bandage was compressed 0.3 mm at a speed of 50 mm / min with a disk-shaped probe having a tip of 3 mm in diameter was measured using a rheometer (manufactured by San Kagaku KK). This test was performed three times to compare the buffer capacity. Table 2 shows the results.

[Table 2]

Adhesion test: Second index finger of 20 subjects
The emergency bandages of Examples and Comparative Examples were attached to the joints, and a five-stage evaluation was made on the feeling of application and impact relaxation. Table 3 shows the results.

[Table 3]

[0037]

According to the emergency bandage of the present invention, the impact force from the outside world is effectively absorbed or alleviated by the cushioning material, so that severe pain is not given to the affected part at the time of careless contact. In addition, since the capillaries near the affected part can be pressed by the pressing force provided by the cushion material, it has a high hemostatic effect. Since the cushioning material is directly fixed to the base sheet, there is no possibility of falling off during use. Furthermore, since the flat pad is used, the first-aid bandage itself can be made thinner, less noticeable, easier to use, and less uncomfortable when used.

According to the second aspect of the present invention, the cushioning material exposed to the outside can directly absorb the impact force from the outside world, so that the cushioning material has a higher cushioning property and the function of protecting the affected part is improved. Can be planned.

According to the emergency bandage according to the third aspect, the compressive force from the cushion material is directly transmitted to the affected part, so that a higher hemostatic effect can be obtained. Further, since the impact force from the outside is transmitted to the cushion material via the base sheet and the pressure-sensitive adhesive layer, the transmission of the impact force from the outside to the affected part can be more reliably prevented.

According to the fourth aspect of the present invention, since the cushion material is located inside the bandage, it can be used safely for a long time. Further, since a part of the impact force from the outside is absorbed by the plurality of base sheets and the pressure-sensitive adhesive layer, transmission of the impact force from the outside to the affected part can be more reliably prevented.

According to the emergency bandage according to the fifth aspect, the capillaries near the affected part can be strongly pressed by the pressing force caused by the gas sealed in the cushion material, and thus has a high hemostatic effect.

According to the emergency bandage according to the sixth aspect, it is possible to obtain a high buffering effect by the elastic force of the thin film itself constituting the cushioning material, in addition to the buffering effect by the enclosed gas. Also, since the influence of the expansion and contraction of the gas is small, a stable buffering effect can be maintained.

According to the emergency bandage according to the seventh aspect, the production of the cushioning material is easy and the feeling of use can be further improved.

According to the emergency bandage according to the eighth aspect, it is possible to make the entire body thin, without discomfort, and further easy to use. In addition, packaging of the bandage itself is also facilitated.

According to the emergency bandage according to the ninth aspect, in addition to the cushioning effect of the cushion material, a further protective effect of the affected part can be obtained by the cushioning property of the base sheet itself.
