Description

One aspect of the disclosure relates to hemostatic tapes.

Various types of hemostatic tapes have been conventionally known. Patent Document 1 describes a hemostatic tape provided with a base material layer and an adhesive layer provided on the surface of the base material layer. The base material layer has an stretchable portion and a non-extendable portion that is bonded to the stretchable portion and has non-extendability. The elongated portion and the non-extended portion are independent members. The non-extended portion is provided with a hemostatic pad that is applied to the wound site.

In this hemostatic tape, a crease is formed around the joint between the end of the stretched portion and the end of the non-stretched portion, and the stretched portion is folded along the crease in the non-stretched portion. Further, at the time of use, the extended portion is developed from the non-extended portion through the above crease. When the unfolded stretched portion is pulled with the non-stretched portion fixed, the hemostatic tape exhibits a single band shape. The above-mentioned adhesive layer is a layer in which an elongated portion and a non-extended portion are bonded together in order to maintain a laminated state of the base material. The adhesive layer formed on the elongated portion is detachably adhered to the adhesive layer provided on the non-extended portion at the joint portion described above.

Japanese Unexamined Patent Publication No. 2019-111151

In the hemostatic tape described above, the stretched portion is removable from the non-stretched portion provided with the hemostatic pad. Therefore, it is possible to rejoin the extended portion removed from the non-extended portion to the non-extended portion. However, in the hemostatic tape, when the extended portion is attached to and detached from the non-extended portion where the hemostatic pad is provided, there is a concern that the extended portion is reused to induce cross-infection. Therefore, in order to prevent cross-infection, it is required that a part of the hemostatic tape can be reliably cut without reusing a part of the hemostatic tape.

The hemostatic tape according to one form of the present disclosure is connected to a plaster portion having a first base material layer, a first adhesive layer and a pad portion, and a foldable adhesive plaster portion to the adhesive plaster portion, and is connected to the second base material layer. And a hemostatic band portion having a second adhesive layer, and the adhesive plaster portion can separate the first portion including the pad portion, the second portion continuous with the hemostatic band portion, and the first portion and the second portion from each other. It has a cutting portion and a cutting portion.

In this hemostatic tape, the tourniquet portion is foldably connected to the adhesive plaster portion having the pad portion. Therefore, compression hemostasis can be performed by applying the pad portion of the adhesive plaster portion to the wound portion of the arm or the like and deploying the tourniquet portion with the first adhesive layer of the adhesive plaster portion attached and wrapping the tourniquet portion around the arm or the like. .. Further, the adhesive plaster portion of the hemostatic tape has a first portion including a pad portion, a second portion connected to the tourniquet portion, and a cutting portion that enables the first portion and the second portion to be separated from each other. Therefore, after performing compression hemostasis, the second portion and the tourniquet portion can be removed from the arm or the like by separating the first portion and the second portion of the adhesive plaster portion through the cut portion. Therefore, by separating the second part from the first part of the adhesive plaster portion through the cut portion provided in the adhesive plaster portion, the tourniquet portion can be made non-detachable with respect to the first portion of the adhesive plaster portion including the pad portion. it can. Therefore, the tourniquet portion, which is a part of the hemostatic tape, can be reliably cut, and cross-infection can be prevented more reliably.

According to the present disclosure, a part of the hemostatic tape can be reliably cut.

(First Embodiment)
First, the hemostatic tape according to the first embodiment will be described with reference to FIGS. 1 (a) and 1 (b). FIG. 1A is a plan view showing an exemplary hemostatic tape 1 according to the first embodiment. FIG. 1B is a cross-sectional view taken along the line AA of the hemostatic tape 1. As shown in FIGS. 1 (a) and 1 (b), the hemostatic tape 1 has a pad portion 2 that is applied to the wound portion. The hemostatic tape 1 has a band shape in a plan view. The band shape includes, for example, an elongated plate shape, a line shape, and a string shape.

The hemostatic tape 1 has, for example, a rectangular shape having a long side extending in the first direction D1 and a short side extending in the second direction D2 intersecting the first direction D1 (orthogonal as an example). As an example, the lower limit of the length of the hemostatic tape 1 in the first direction D1 is 40 mm, 50 mm or 60 mm, and the upper limit of the length of the hemostatic tape 1 in the first direction D1 is 200 mm, 180 mm or 150 mm. Is. For example, the upper limit of the width of the hemostatic tape 1 in the second direction D2 is 70 mm, 60 mm, or 50 mm, and the lower limit of the width of the hemostatic tape 1 in the second direction D2 is 20 mm, 30 mm, or 40 mm. However, the above-mentioned lengths of the hemostatic tape 1 are not limited to the above-mentioned values and can be changed as appropriate.

The hemostatic tape 1 is, for example, unfolded along the first direction D1 and further wound along the first direction D1. The hemostatic tape 1 includes a bandage portion 10 having a pad portion 2, a tourniquet zone portion 20 folded into the bandage portion 10, and a sticking portion 30 folded into the tourniquet portion 20. The hemostatic tape 1 has a three-layer structure of a bandage portion 10, a tourniquet portion 20, and a sticking portion 30, and the adhesive plaster portion 10, the tourniquet portion 20, and the sticking portion 30 are Z-shaped. As an example, the adhesive plaster portion 10, the tourniquet zone portion 20, and the sticking portion 30 exhibit a band shape extending in the first direction D1. For example, the adhesive plaster portion 10, the tourniquet portion 20, and the sticking portion 30 may be independent members.

The adhesive plaster portion 10 has, for example, non-stretchability. In this case, the adhesive plaster portion 10 corresponds to the non-stretched portion of the hemostatic tape 1. The adhesive plaster portion 10 includes a first portion 10A having a pad portion 2, a second portion 10B connected to the tourniquet portion 20, and a cutting portion 10C that enables the first portion 10A and the second portion 10B to be separated from each other. Have. A crease is formed around the joint portion C1 between the second portion 10B and one end of the first direction D1 of the tourniquet portion 20, and the tourniquet portion 20 is folded into the adhesive plaster portion 10 through the crease. Further, a crease is also formed around the joint portion C2 between the other end of the first direction D1 of the tourniquet portion 20 and one end of the first direction D1 of the sticking portion 30.

FIG. 1B shows a state in which the adhesive plaster portion 10, the tourniquet portion 20, and the sticking portion 30 are separated from each other for easy understanding. However, the adhesive plaster portion 10, the tourniquet portion 20, and the sticking portion 30 are in close contact with each other in a state of being lined up in the third direction D3, which is the laminating direction, before the use of the hemostatic tape 1, for example. That is, before use, the tourniquet portion 20 is in close contact with the adhesive plaster portion 10, and the sticking portion 30 is in close contact with the hemostatic band portion 20.

When the hemostatic tape 1 is used, the sticking portion 30 can be unfolded from the tourniquet portion 20, and the tourniquet portion 20 can be unfolded from the adhesive plaster portion 10. When unfolded, the bandage portion 10, the tourniquet portion 20, and the sticking portion 30 are arranged in this order along the first direction D1. At the end of the sticking portion 30 opposite to the tourniquet portion 20, for example, a tab 40 that can be picked with a finger or the like is provided, and the tab 40 is picked and the sticking portion 30 is held in the tourniquet band. It is possible to perform the above development by peeling from the portion 20. In the following, the state in which the adhesive plaster portion 10, the tourniquet portion 20 and the pasting portion 30 are deployed is referred to as the “deployed state”, and the hemostatic band portion 20 is laminated on the adhesive plaster portion 10 and pasted on the hemostatic zone portion 20. The state in which the attachment portions 30 are laminated may be referred to as a "laminated state".

The adhesive plaster portion 10 has a first base material layer 11 and a first adhesive layer 12. The adhesive plaster portion 10 is a non-stretchable portion where the pad portion 2 is fixed and is fixed around the wound portion, and exhibits a band shape. The first base material layer 11 has a surface 11b facing the tourniquet portion 20 side and an adhesive surface 11c facing the opposite side of the tourniquet portion 20. The first adhesive layer 12 is provided on the adhesive surface 11c. The tourniquet portion 20 is adhered to the surface 11b with a separable adhesive force.

A release agent layer may be provided on at least a part of the surface 11b. In this case, the tourniquet portion 20 is easily peeled off from the adhesive plaster portion 10. The length (long side length) of the adhesive plaster portion 10 in the first direction D1 is, for example, 40 mm or more and 200 mm or less, and the width (short side length) of the adhesive plaster portion 10 in the second direction D2 is 20 mm or more and 70 mm. It is as follows. The thickness of the adhesive plaster portion 10 in the third direction D3 is, for example, 0.02 mm or more and 0.50 mm or less.

The second portion 10B of the adhesive plaster portion 10 is a portion continuous with the tourniquet portion 20. One end of the first direction D1 of the adhesive plaster portion 10 is included, and one end of the first direction D1 of the adhesive plaster portion 10 constitutes a joint portion C1 with the tourniquet portion 20. In the second portion 10B, one end of the first direction D1 of the adhesive plaster portion 10 is folded back toward the tourniquet portion 20. At least a part of the second portion 10B may project to the end of the hemostatic tape 1 in the first direction D1 when viewed from the third direction D3. That is, one end of the adhesive plaster portion 10 when viewed from the third direction D3 may protrude to the outside of the first direction D1. The first base material layer 11 of the adhesive plaster portion 10 is made of, for example, a resin film, paper or cloth. When the first base material layer 11 is a resin film, the resin constituting the first base material layer 11 may be, for example, a polyolefin such as polyethylene or polypropylene, or a synthetic resin such as polyester or polyurethane.

The first adhesive layer 12 is a layer that adheres around the wound site when the hemostatic tape 1 is used. The pad portion 2 is adhered to the first adhesive layer 12. The first adhesive layer 12 is provided on the adhesive surface 11c of the first base material layer 11. One end of the first adhesive layer 12 in the first direction D1 is folded back and faces the tourniquet portion 20 side, and is adhered to the second adhesive layer 22 described later of the tourniquet portion 20. The first adhesive layer 12 may be inseparably adhered to the second adhesive layer 22. The thickness of the first adhesive layer 12 is, for example, 5 μm or more and 100 μm or less. The first adhesive layer 12 may be covered with a protective sheet or the like in order to prevent unintended adhesion to other members or the like before the hemostatic tape 1 is used.

For example, the first adhesive layer 12 is formed by applying an adhesive to the adhesive surface 11c of the first base material layer 11. The first adhesive layer 12 may be applied to the entire adhesive surface 11c of the first base material layer 11, or may be applied to a part of the adhesive surface 11c of the first base material layer 11. When the first adhesive layer 12 is applied to a part of the adhesive surface 11c of the first base material layer 11, the first adhesive layer 12 is applied in a pattern (for example, a dot shape, a stripe shape, a concentric circle shape, etc.). It may be applied irregularly. The pressure-sensitive adhesive contained in the first adhesive layer 12 can be attached to, for example, the human body. The pressure-sensitive adhesive contained in the first adhesive layer 12 may be an acrylic pressure-sensitive adhesive, a synthetic rubber-based pressure-sensitive adhesive, a urethane-based pressure-sensitive adhesive, or a silicone-based pressure-sensitive adhesive.

The adhesive force of the first adhesive layer 12 may be stronger than the adhesive force of the second adhesive layer 22 described later in the tourniquet portion 20. For example, the adhesive strength of the first adhesive layer 12 is 0.3 N / 25 mm or more and 5.0 N / 25 mm or less. Since the adhesive strength of the first adhesive layer 12 is 0.3 N / 25 mm or more, the tourniquet portion 20 is developed even after the first adhesive layer 12 is adhered to the user's skin H (see FIG. 2). It is possible to more reliably suppress the detachment of the adhesive plaster portion 10 when the condition is set or when a tensile load is applied to the tourniquet portion 20. When the adhesive strength of the first adhesive layer 12 is 4N / 25 mm or more, the first adhesive layer 12 can be more strongly adhered to the skin H.

When the adhesive strength of the first adhesive layer 12 is 5.0 N / 25 mm or less, the adhesive plaster portion 10 can be easily detached from the skin H. For example, the ratio of the area of the pad portion 2 to the area of the adhesive plaster portion 10 when viewed from the third direction D3 may be 5% or more and 40% or less. In this case, both the area where the first adhesive layer 12 adheres to the skin H and the area where the pad portion 2 is applied to the wound portion of the skin H can be more reliably secured.

The tourniquet portion 20 has elasticity, for example. In this case, the tourniquet portion 20 corresponds to an elongated portion of the hemostatic tape 1. The tourniquet portion 20 has a band shape when the hemostatic tape 1 is in a laminated state and the pad portion 2 is attached to the wound portion. The tourniquet portion 20 has a second base material layer 21 and a second adhesive layer 22 facing the adhesive plaster portion 10 side. The second base material layer 21 has, for example, a surface 21b in contact with the skin H (see FIG. 2) and an adhesive surface 21c to which the second adhesive layer 22 adheres.

The second adhesive layer 22 has an inner surface 22b that adheres to the adhesive surface 21c and an outer surface 22c that faces the opposite side of the inner surface 22b. For example, the length of the tourniquet portion 20 before extension in the first direction D1 is 40 mm or more and 200 mm or less, and the width of the tourniquet portion 20 before extension 20 in the second direction D2 is 20 mm or more and 70 mm or less. The thickness of the third direction D3 of the front tourniquet portion 20 is 0.05 mm or more and 0.30 mm or less. However, these length, width and thickness values are not limited to the above and can be changed as appropriate.

As described above, one end of the tourniquet portion 20 in the first direction D1 constitutes a joint portion C1 of the adhesive plaster portion 10 with the second portion 10B. In the joint portion C1, the second adhesive layer 22 of the tourniquet portion 20 is overlapped with the second portion 10B of the adhesive plaster portion 10. The second base material layer 21 of the tourniquet portion 20 is, for example, a resin film, but may be made of cloth, or may be a woven fabric, a knitted fabric, or a non-woven fabric.

The tourniquet portion 20 (second base material layer 21) has elasticity, for example, and even if the width of the second direction D2 of the tourniquet portion 20 becomes narrow when a tensile load is applied to the first direction D1. Good. When the tourniquet portion 20 is made of a resin material, the resin material contained in the tourniquet portion 20 contains an elastomer. The type of elastomer of the tourniquet portion 20 is not particularly limited, and may include, for example, at least one of a styrene-based elastomer and an olefin-based elastomer.

More specifically, the elastomer of the second base material layer 21 includes styrene-isoprene-styrene block copolymer (SIS), styrene-butadiene-styrene block copolymer (SBS), and styrene-ethylene / butylene-styrene block copolymer (SEBS). ), Polypropylene, or polyolefin (for example, ethylene vinyl acetate, ethylene-propylene copolymer, ethylene-propylene-dienter polymer), polypropylene copolymer, polypropylene homopolymer, etc.).

The resin material of the tourniquet portion 20 may contain other components in addition to the elastomer. For example, the resin material of the second base material layer 21 is a stiffening agent (for example, polystyrene, polyα-methylstyrene, polyester, epoxy resin, polyolefin, kumaron-inden resin), a viscosity reducing agent, a plasticizing agent, and a tackifier. (For example, aliphatic hydrocarbon tackifiers, aromatic hydrocarbon tackifiers, terpene resin tackifiers, hydride terpene resin tackifiers), pigments, antioxidants, antioxidants, adhesives, anti-stickiness It may contain an agent, a slip agent, a heat stabilizer, a light stabilizer, a foaming agent, a glass bubble, a starch, a metal salt, a microfiber, and the like, and is not particularly limited.

The characteristics of the tourniquet portion 20 (for example, strength, expansion / contraction characteristics, or wrapping characteristics) can be appropriately changed depending on the configuration or application of the hemostatic tape 1. When the tourniquet portion 20 has elasticity and the width of at least a part of the tourniquet portion 20 narrows when a tensile load is applied to the first direction D1, as in the present embodiment, the tourniquet portion 20 returns. The load and the degree of decrease in the length of the short side of the tourniquet portion 20 can also be changed as appropriate.

In the present embodiment, the maximum long side length of the second base material layer 21 when the tourniquet portion 20 is extended can be, for example, 3.5 times or more that of the second base material layer 21 in the laminated state. As a specific example, when the long side length of the second base material layer 21 in the laminated state is 80 mm, the maximum long side length of the second base material layer 21 in the unfolded state can be 280 mm or more or 350 mm or more. As a result, the dimensions of the tourniquet portion 20 including the second base material layer 21 before stretching in the laminated state (for example, the length of the long side of the second base material layer 21 before stretching in the first direction D1) can be reduced. Is possible.

The second adhesive layer 22 is a layer for attaching the tourniquet portion 20 to the adhesive plaster portion 10, and adheres to the adhesive plaster portion 10 with a separable adhesive force. The second adhesive layer 22 maintains a state in which the tourniquet portion 20 is laminated on the adhesive plaster portion 10. The second adhesive layer 22 may be, for example, an adhesive layer, or may be provided with a joining member such as a mechanical fastener (hook-and-loop fastener). The second adhesive layer 22 is inseparably adhered to the first adhesive layer 12 of the adhesive plaster portion 10 at the joint portion C1, for example. As an example, the thickness of the second adhesive layer 22 is 5 μm or more and 100 μm or less.

For example, the second adhesive layer 22 is formed by applying an adhesive to the adhesive surface 21c of the second base material layer 21. The second adhesive layer 22 may be applied to the entire surface of the adhesive surface 21c of the second base material layer 21, or may be applied to a part of the adhesive surface 21c of the second base material layer 21. When the second adhesive layer 22 is applied to a part of the adhesive surface 21c of the second base material layer 21, the second adhesive layer 22 may be applied in a pattern or irregularly. .. The pressure-sensitive adhesive contained in the second adhesive layer 22 may be the same as the pressure-sensitive adhesive of the first adhesive layer 12 described above, and is not particularly limited.

The lower limit of the adhesive force of the second adhesive layer 22 (for example, the force applied when the tourniquet portion 20 provided with the second adhesive layer 22 is peeled off from the adhesive plaster portion 10) is 0.1 N / 25 mm as an example. Alternatively, it is 0.3 N / 25 mm, and the upper limit of the adhesive force of the second adhesive layer 22 is 5 N / 25 mm or 2.5 N / 25 mm. When the adhesive strength of the second adhesive layer 22 is 0.1 N / 25 mm or more, it is possible to prevent the tourniquet portion 20 from being unintentionally unfolded from the adhesive plaster portion 10. When the adhesive strength of the second adhesive layer 22 is 5 N / 25 mm or less, the tourniquet portion 20 can be easily detached from the adhesive plaster portion 10.

The above-mentioned adhesive force corresponds to, for example, a 90-degree peeling force measured as follows (for example, a 90-degree peeling force of the tourniquet portion 20 with respect to the adhesive plaster portion 10 via the second adhesive layer 22). It can be an index of ease of deployment from the adhesive plaster portion 10 of the portion 20. As an example of the measurement method, first, a test piece having a tourniquet portion 20 provided with the second adhesive layer 22 having a size of 25 mm × 50 mm is prepared. Next, a 25 mm × 210 mm piece of paper is attached to a half (25 mm × 25 mm) portion of the test piece, and the adhesive plaster portion 10 which is an adherend is attached to an aluminum plate of 50 mm × 100 mm. The aluminum plate is arranged so that its long side follows the direction in which the sample is peeled off. Then, using a 2 kg roller, the exposed portion (25 mm × 25 mm) of the test piece in the sample is attached to the adherend. Then, using a tensile tester or the like, the adhesive force when the sample is peeled from the adherend is measured at a speed of 300 mm / min. The 90-degree peeling force may be an average value of the moving distance from the start of peeling up to 25 mm.

The sticking portion 30 has, for example, non-stretchability. As an example, the sticking portion 30 has a third base material layer 31 and a third adhesive layer 32 that adheres to the tourniquet portion 20. The third base material layer 31 has a surface 31b exposed to the outside and an adhesive surface 31c on which the third adhesive layer 32 is provided. The third adhesive layer 32 has an inner surface 32b that adheres to the third base material layer 31 and an outer surface 32c that adheres to the tourniquet portion 20. For example, one end of the first direction D1 of the third adhesive layer 32 constitutes a joint portion C2 with the tourniquet portion 20, and a tab 40 is attached to the other end of the first direction D1 of the third adhesive layer 32. Has been done. Each of the material of the third base material layer 31 and the material of the third adhesive layer 32 is the same as, for example, the material of the first base material layer 11 and the material of the first adhesive layer 12 (or the second adhesive layer 22). It may be. Further, the sticking portion 30 may have elasticity, and in this case, the material of the third base material layer 31 may be the same as the material of the second base material layer 21 of the tourniquet portion 20. ..

The tab 40 functions as a pinch portion that is pinched when the hemostatic tape 1 is unfolded, and has, for example, non-stretchability. The tab 40 is attached to the third adhesive layer 32 of the attachment portion 30 so as to protrude from the end portion of the attachment portion 30 in the first direction D1. In the laminated state, the tab 40 is laminated so as to overlap the second base material layer 21 of the tourniquet portion 20, for example. The tab 40 may be colored in a color different from that of other parts of the hemostatic tape 1. In this case, the position of the tab 40 of the hemostatic tape 1 can be easily grasped. The length of the portion where the tab 40 is exposed in the first direction D1 is, for example, 0.1 mm or more and 20 mm or less. The tab 40 is made of, for example, a resin film, paper or cloth. The thickness of the tab 40 may be, for example, about 80 μm.

Next, the adhesive plaster portion 10 will be described in more detail. As described above, the adhesive plaster portion 10 makes the first portion 10A having the pad portion 2, the second portion 10B connected to the tourniquet portion 20, and the first portion 10A and the second portion 10B separable from each other. It is provided with a cutting portion 10C. The cut portion 10C is located, for example, at the boundary portion between the first portion 10A and the second portion 10B, but the position of the boundary portion can be changed as appropriate.

In FIGS. 1A and 1B, as an example, the cutting portion 10C is provided at a position closer to the joint portion C1 (closer to the tourniquet portion 20) than the center of the first direction D1 of the adhesive plaster portion 10. Shown. When the cut portion 10C is provided at a position closer to the joint portion C1, the distance of the cut portion 10C from the pad portion 2 can be increased, so that the pad portion 2 is less likely to be peeled off from the wound portion when the adhesive plaster portion 10 is torn by the cut portion 10C. can do. Further, when the cut portion 10C is provided at a position closer to the joint portion C1, the position of the cut portion 10C can be brought closer to the tourniquet portion 20, so that when the tourniquet portion 20 is removed from the skin H, the cut portion 10C is together with the tourniquet portion 20. The second portion 10B can be easily separated from the first portion 10A.

The cut portion 10C is a portion for allowing the adhesive plaster portion 10 to be divided in the middle portion of the adhesive plaster portion 10 by a finger or the like, and the second portion 10B can be separated from the first portion 10A by cutting the cut portion 10C. is there. Since the separated second portion 10B cannot be joined to the first portion 10A again, for example, the second portion 10B, the tourniquet portion 20, and the sticking portion 30 cannot be reused. In this case, it is possible to prevent the tourniquet portion 20 and the like from being reused and promote the disposal of the tourniquet portion 20 and the like.

The cut portion 10C may, for example, penetrate the first base material layer 11 and the first adhesive layer 12 of the adhesive plaster portion 10 in the third direction D3. The cut portion 10C may extend from one end to the other end of the second direction D2 of the adhesive plaster portion 10, or may be provided on a part of the adhesive plaster portion 10 from one end to the other end of the second direction D2. .. The cut portion 10C may extend linearly, or may extend in a curved shape such as a corrugated shape or an arc shape, and the shape, size, number, and arrangement mode of the cut portion 10C are not particularly limited.

The cut portion 10C may be, for example, a perforation or a fragile portion that is more easily broken than other portions of the adhesive plaster portion 10. When the cut portion 10C is a perforation, a plurality of holes may be arranged in the cut portion 10C along the second direction D2. In this case, the cutting portion 10C is made by, for example, a punching blade that forms a plurality of holes. Further, the cut portion 10C may be manufactured by embossing such as heat embossing. As described above, the cutting portion 10C may be a portion that is easier to cut than the other portions of the adhesive plaster portion 10, and the method for producing the cutting portion 10C is not particularly limited.

Next, an example of how to use the hemostatic tape 1 will be described with reference to FIGS. 2 to 5. An example of wrapping the hemostatic tape 1 around the user's arm will be described below. First, as shown in FIGS. 2A and 2B, the wound portion is covered with the pad portion 2, the hemostatic tape 1 is attached to the skin H, and the tab 40 is pinched with a finger to pinch the tourniquet portion 20. The pasting portion 30 is expanded from.

Next, as shown in FIGS. 3A and 3B, the tourniquet portion 20 is developed from the adhesive plaster portion 10 and the tab 40, the pasting portion 30, the tourniquet portion 20 and the adhesive plaster portion 10 are aligned. While deploying so as to form a shape, the tourniquet portion 20 and the sticking portion 30 are wrapped around the arm along the skin H. At this time, the tourniquet portion 20 and the sticking portion 30 may be wound while extending the tourniquet portion 20. Even when the tourniquet portion 20 is stretched, for example, since the adhesive plaster portion 10 and the sticking portion 30 have non-stretchability, the adhesive plaster portion 10 and the sticking portion 30 are hardly stretched.

Then, as shown in FIGS. 4A and 4B, the third adhesive layer 32 of the sticking portion 30 wound around the arm once is stuck on the adhesive plaster portion 10 to perform pressure hemostasis. For example, after 5 minutes or more and 10 minutes or less have passed since the compression hemostasis was performed, the compression stop was completed and the amputation was performed as shown in FIGS. 4 (b), 5 (a) and 5 (b). The second part 10B, the tourniquet part 20 and the sticking part 30 are separated from the part 10C, and the second part 10B, the tourniquet part 20 and the sticking part 30 are discarded. Then, after protecting the wound portion with the pad portion 2 with the first portion 10A of the adhesive plaster portion 10 attached to the skin H for about 2 hours, for example, the first portion 10A is peeled off from the skin H and the first portion 10A Discard.

Next, the action and effect obtained from the hemostatic tape 1 according to the present embodiment will be described. In the hemostatic tape 1, the tourniquet portion 20 is foldably connected to the adhesive plaster portion 10 having the pad portion 2. Therefore, the pad portion 2 of the adhesive plaster portion 10 is applied to the wound portion of the arm or the like, and the tourniquet portion 20 is expanded with the first adhesive layer 12 of the adhesive plaster portion 10 attached and wrapped around the arm or the like to compress and stop bleeding. It can be performed.

Further, the adhesive plaster portion 10 of the hemostatic tape 1 can separate the first portion 10A including the pad portion 2, the second portion 10B connected to the tourniquet portion 20, and the first portion 10A and the second portion 10B from each other. It has a cutting portion 10C and the like. Therefore, after performing compression hemostasis, the tourniquet portion 20 and the second portion 10B are removed from the arm or the like by separating the second portion 10B from the first portion 10A of the adhesive plaster portion 10 via the cutting portion 10C. Can be done.

Therefore, by separating the second portion 10B from the first portion 10A of the adhesive plaster portion 10 via the cutting portion 10C provided in the adhesive plaster portion 10, the tourniquet is attached to the first portion 10A of the adhesive plaster portion 10 including the pad portion 2. The portion 20 can be made non-detachable. Therefore, the tourniquet portion 20 which is a part of the hemostatic tape 1 can be reliably cut, and cross-infection can be prevented more reliably.

The bandage portion 10 may have non-stretchability. In this case, the elasticity of the adhesive plaster portion 10 causes stress when the adhesive plaster portion 10 is attached to the skin H, and it is possible to prevent the skin H from having trouble due to the stress.

The hemostatic tape 1 includes a sticking portion 30 connected to the opposite side of the tourniquet portion 20 from the adhesive plaster portion 10, and the sticking portion 30, the tourniquet portion 20 and the adhesive plaster portion 10 have a Z shape. May be good. In this case, the hemostatic tape 1 has a three-layer structure consisting of a plaster portion 10, a tourniquet portion 20, and a sticking portion 30. Therefore, the tourniquet portion 20 is folded in the adhesive plaster portion 10, and the attachment portion 30 is folded in the hemostatic band portion 20, so that the total length of the hemostatic tape 1 can be shortened and the hemostatic tape 1 can be made compact. ..

The sticking portion 30 may have non-stretchability. In this case, when the tourniquet portion 20 is expanded from the adhesive plaster portion 10 and the adhesive portion 30 is attached to the adhesive plaster portion 10, the adhesive portion 30 does not easily expand or contract, so that the adhesive portion 30 can be easily attached to the skin H. Can be pasted.

The tourniquet portion 20 may have elasticity. In this case, since the tourniquet portion 20 can be stretched when deployed, the length of the tourniquet portion 20 before use can be shortened. Therefore, the hemostatic tape 1 can be made more compact.

(Second Embodiment)
Next, the hemostatic tape 51 according to the second embodiment will be described with reference to FIGS. 6 (a) and 6 (b). As shown in FIGS. 6A and 6B, the bandage portion 10 has a two-layer structure consisting of a bandage portion 10 having a pad portion 2 and a tourniquet portion 20 folded into the adhesive plaster portion 10. And the tourniquet portion 20 is V-shaped. That is, the hemostatic tape 51 does not have the above-mentioned sticking portion 30.

The length of the hemostatic tape 51 having no sticking portion 30 in the first direction D1 is longer than, for example, the length of the hemostatic tape 1 having the sticking portion 30 described above in the first direction D1. As a result, even the V-shaped two-layer structure hemostatic tape 51 can be reliably wrapped around the arm or the like. Since the configuration of a part of the hemostatic tape 51 according to the second embodiment is the same as the configuration of a part of the hemostatic tape 1 described above, the portion overlapping with the configuration of the hemostatic tape 1 will be described below. The description will be omitted as appropriate.

In the hemostatic tape 51, a tab 60 and a peeling portion 72 are provided at an end portion of the tourniquet portion 20 opposite to the joint portion C1. The tab 60 is attached to, for example, the outer surface 22c of the second adhesive layer 22 of the tourniquet portion 20. Like the tab 40 described above, the tab 60 functions as a knob portion, and for example, the tab 60 projects from the end portion of the tourniquet portion 20 in the first direction D1. By pulling the pinched tab 60 away from the adhesive plaster portion 10, the tourniquet portion 20 can be easily deployed from the adhesive plaster portion 10.

The peeling portion 72 is attached to, for example, the surface of the tourniquet portion 20 opposite to the tab 60. As an example, the peeling portion 72 is attached to the surface 21b of the second base material layer 21 of the tourniquet portion 20 via the adhesive layer 71. The adhesive layer 71 is a layer for attaching the tourniquet portion 20 around the arm to the surface 11b of the first base material layer 11 of the adhesive plaster portion 10. The peeling portion 72 is provided to protect the adhesive layer 71 before use, and is peeled from the adhesive layer 71 at the time of use. The adhesive layer 71 and the peeling portion 72 may be attached to the second adhesive layer 22 by omitting the tab 60. In this case, the adhesive layer 71 is attached to the adhesive plaster portion 10 by twisting the tourniquet portion 20. Can be pasted.

As described above, in the hemostatic tape 51 according to the second embodiment, the adhesive plaster portion 10 includes the first portion 10A including the pad portion 2, the second portion 10B connected to the tourniquet zone portion 20, the first portion 10A, and the first portion 10. It has a cutting portion 10C that allows the two portions 10B to be separated from each other. Therefore, after performing pressure hemostasis, the second portion 10B can be separated from the first portion 10A of the adhesive plaster portion 10 via the cutting portion 10C. Therefore, the tourniquet portion 20 can be made non-detachable with respect to the first portion 10A of the adhesive plaster portion 10 including the pad portion 2, so that the same effect as that of the first embodiment can be obtained.

Further, in the hemostatic tape 51, the adhesive plaster portion 10 and the tourniquet portion 20 form a V shape. Therefore, since the tourniquet can be wound only by unfolding the tourniquet portion 20 from the adhesive plaster portion 10, the unfolding and wrapping can be performed more easily than in the case of the three-layer structure. That is, since the adhesive plaster portion 10 and the tourniquet portion 20 form a V shape, the folded tourniquet portion 20 can be unfolded and the hemostatic tape 51 can be easily attached to the skin H.

Further, in the case of the hemostatic tape 51 having a two-layer structure, the direction in which the hemostatic tape 51 is attached to the skin H can be easily understood before unfolding and winding. That is, in the hemostatic tape 51 having a two-layer structure, the direction in which the hemostatic tape 51 is attached to the skin H can be intuitively understood, so that the hemostatic tape 51 can be more easily attached.

Each embodiment of the hemostatic tape according to the present disclosure has been described above. However, the shape, size, number, material, and arrangement of each part of the hemostatic tape according to the present disclosure are not limited to the above-described embodiments and can be appropriately changed. For example, as shown in FIGS. 7 (a) and 7 (b), the number and arrangement positions of the cut portions provided in the adhesive plaster portion 10 can be appropriately changed.

FIG. 7A shows an example in the hemostatic tape 1 described above, in which the first portion 10A of the adhesive plaster portion 10 is further provided with the cutting portion 10D, and the second portion 10B is further provided with the cutting portion 10E. .. The bandage portion 10 has, for example, a plurality of cut portions 10D. As an example, the cutting portions 10D, 10C, and 10E may be arranged at equal intervals along the first direction D1. In this way, when the adhesive plaster portion 10 has a plurality of cut portions, the adhesive plaster portion 10 can be divided at a desired position.

FIG. 7B shows an example in the hemostatic tape 51 described above in which the first portion 10A of the adhesive plaster portion 10 is further provided with the cutting portion 10F, and the second portion 10B is further provided with the cutting portion 10G. The arrangement of the cutting portion 10F and the cutting portion 10G can be, for example, the same as the arrangement of the cutting portion 10D and the cutting portion 10E in FIG. 7 (a). The hemostatic tape 51 shown in FIG. 7B also has a plurality of cut portions, so that the adhesive plaster portion 10 can be divided at a desired position.

Further, in the above-described embodiment, the hemostatic tapes 1 and 51 wrapped around the user's arm and the like have been described.
