Description

  The present invention relates to a hemostatic adhesive bandage, and more particularly to a hemostatic adhesive bandage that can be easily peeled off from a liner and can be manufactured at low cost.

  Conventionally, after intravenous injection, blood collection, infusion, or the like, a method of applying hemostasis to a puncture part from which a needle has been removed by applying a small bandage for hemostasis to the puncture part is generally used. As such a hemostatic bandage, there is known one in which a sheet having an adhesive portion and a hemostatic pad is detachably bonded to a liner serving as a mount.

  However, in many of this type, the adhesive part of the sheet is attached to the entire surface of the liner, so it is difficult to peel the sheet from the liner, and the adhesive part is difficult to stick around the finger. It has problems in use, and a sanitary problem has been pointed out because the finger touches the adhesive part.

  In order to solve such a problem, a hemostatic adhesive bandage is known in which a part of the adhesive portion of the sheet is provided with a detachable piece separate from the liner, the piece can be picked, and the sheet can be peeled off from the liner together with the piece. ing. Further, Patent Document 1 discloses a hemostatic bandage that can be provided with an adhesive part leaving a non-adhesive part along one side of the sheet, and can be picked and peeled off from the liner.

  However, the former type, in which a peelable piece separate from the liner is interposed in part of the adhesive part of the sheet, increases the number of parts and the manufacturing process, leading to increased costs and must be disposed of after use. The problem was that the amount of trash that had to be increased.

  In addition, the type that can be picked from the non-adhesive portion along one side of the latter sheet and peeled off from the liner has been difficult to manufacture for the following reasons. That is, the non-adhesive part is provided with a non-adhesive part on a part of the sheet from the beginning, or an adhesive part is formed on the entire back surface of the sheet in advance, and the part is subsequently treated with a chemical or the like to be adhered. A method of removing the property and forming a non-adhesive part is conceivable. However, when a non-adhesive portion is provided on a part of the sheet from the beginning, not only the number of processes is increased, but also mechanical accuracy is required in manufacturing, which is not easy. In addition, in the method of forming the adhesive part on the entire back surface of the sheet in advance and processing the part later with a drug or the like to form a non-adhesive part, not only the number of steps is increased, but also a chemical for treatment is required, That leads to an increase in cost. In addition, in any of the above methods, an extra sheet material is required for the portion that becomes the non-adhesive portion, which increases the raw material cost of the sheet. Furthermore, there is a possibility that the tape may peel off from the non-adhesive part side after a while after being attached to the puncture part.

  Hereinafter, embodiments of the hemostatic bandage of the present invention will be specifically described based on the drawings. Note that the present invention is not limited to these embodiments.

  FIG. 1 is a front view of the hemostatic bandage of the present invention, and FIG. 2 is a rear view of the hemostatic bandage of the present invention. In the figure, 1 is a liner, 2 is a small piece part, 3 is a sheet, 4 is a pad, 6 is a gap, 11 is a side part, and 21 is a cut line.

  In the hemostatic bandage of FIGS. 1 and 2, ten sheets 3 are detachably bonded to one rectangular liner 1. An adhesive layer is applied to the entire back surface of the sheet 3, and a hemostatic pad 4 is attached to the center of the sheet 3. The plurality of sheets 3 are bonded in two rows in the longitudinal direction of the liner 1. A gap 6 is formed between adjacent sheets 3 in the same row.

  In the region along both side portions 11 of the liner 1, two cut lines 21 are formed for each sheet 3 from the side portions 11 toward the center of the liner 1, and the two The small piece portion 2 is partitioned by the cut line 21. The cut line 21 is formed by a single cut line provided by continuously cutting the liner 1. In the present embodiment, the cut lines 21 are each constituted by a straight line, but can be appropriately selected from a straight line, a curved line, or a combination thereof. In the present invention, the “small piece 2” means that when the leading ends of two cut lines 21 provided for one sheet 3 are connected by a virtual line, the virtual line and the two cuts The line 21 and the site | part divided from the other part by the side part 11 are meant. The same shall apply hereinafter.

  The small piece portion 2 is previously separated from other portions of the liner 1 by two cut lines 21 on both sides thereof. Further, the width of the small piece portion 2, that is, the interval between the two cut lines 21 is formed narrower than the width of the sheet 3, and the sheet 3 is bonded so as to cover the entire small piece portion 2. Therefore, when the small piece portion 2 is erected, the sheet 3 around the small piece portion 2, in particular, the both side portions of the small piece portion 2 is peeled off from the liner 1 and erected. In this embodiment, the sheet 3 is bonded so as to cover the entire small piece portion 2, but may be bonded so as to cover a part of the small piece portion 2.

  FIG. 3 is a front view of a hemostatic bandage according to another embodiment of the present invention, and FIG. 4 is a rear view thereof. In this aspect, a fold line 22 connecting the distal ends of the two cut lines 21 is formed at the base end portion of the small piece portion 2. The fold line 22 is a broken line formed by cutting the liner 1 intermittently, and is formed of a curved line. The folding line 22 can be appropriately selected from a straight line, a curved line, or a combination thereof. Furthermore, the folding line 22 is not limited to the broken line shape as in the present embodiment, and may be folded at the folding line. May be selected as appropriate.

  The small piece portion 2 is preliminarily separated from the other portions of the liner 1 by two cut lines 21 at both sides thereof, and a folding line 22 that is a broken cutting line is provided at the base end portion thereof so that the small piece portion 2 can be bent. Therefore, the small piece portion 2 can be raised from the other portion of the liner 1 by bending upward from the folding line 22 portion. Further, the width of the small piece portion 2, that is, the interval between the two cut lines 21 is formed narrower than the width of the sheet 3, and the sheet 3 is bonded so as to cover the entire small piece portion 2. Therefore, when the small piece portion 2 is erected, the sheet 3 around the small piece portion 2, in particular, the both side portions of the small piece portion 2 is peeled off from the liner 1 and erected. In this embodiment, the sheet 3 is bonded so as to cover the entire small piece portion 2, but may be bonded so as to cover a part of the small piece portion 2.

  Moreover, as shown in FIGS. 5 and 6, in the hemostatic bandage of the present invention, the cutting lines 5 may be formed between the rows of the sheets 3 bonded in two rows in the longitudinal direction of the liner 1. . The cutting line 5 is a cut provided by cutting the liner 1 and the sheet 3 continuously. By forming the cutting line, the handleability at the time of sheet peeling is improved. Further, it is preferable because a state where the sheets are arranged in two rows can be easily formed by forming a cutting line after the sheet is bonded onto the liner, and the manufacturing process can be partially simplified.

  In addition to the rectangular shape as shown in FIG. 1 and the like, the sheet shape in the hemostatic adhesive bandage of the present invention is a wavy shape or straight line in which at least one of the four sides is constituted by a curve, a mountain line, or the like. A shape combined with a curve may be used. For example, when one side of two rows of sheets is corrugated as shown in FIGS. 7 and 8, when peeling the sheet from the liner, the liner between the two rows of sheets is bent to The edge of the sheet is peeled off from the liner. Thereby, a sheet | seat can be easily peeled from a liner by picking the peeled sheet | seat edge part with a finger | toe. As a result, when the hemostatic bandage is used, the sheet can be easily peeled off from both the small piece portion and the adjacent portion of the two rows of sheets, improving the convenience for the user. This is preferable.

  Next, the usage method of the hemostatic adhesive bandage of this invention is demonstrated. 9a-b are partially enlarged cross-sectional views showing a series of states in which the sheet 3 is peeled from the liner 1 of the hemostatic bandage of the present invention, and FIG. 10 is a perspective view in the state of FIG. 9b. FIG. 9 a shows a state before the sheet 3 is peeled. In this state, first, the small piece portion 2 is sandwiched between fingers and bent upward to stand up from other portions of the liner 1 (FIG. 9b). At this time, together with the small piece portion 2, the portion bonded to the small piece portion 2 and the surrounding sheet 3 also stand up and are peeled from the liner 1 at the peripheral portion (FIG. 10). Thereafter, the end of the sheet around the standing small piece 2 can be picked with a finger, and the entire sheet 3 can be completely peeled off from the liner 1.

  Further, when the hemostatic adhesive bandage of the present invention is provided with a fold line 22 such as a broken line shape (FIGS. 9a to 9c), the small piece portion 2 is sandwiched with fingers and bent upward at the fold line 22 portion, whereby the liner 1 Stand up from the other part (FIG. 9b), and then, together with the small piece part 2, the part bonded to the small piece part 2 and the surrounding sheet 3 also stand up, and lift the small piece part 2 while holding it with fingers. If this is the case, the folding line 22 is a broken cutting line, so that the small piece portion 2 is separated from the portion (FIG. 9c). As a result, the entire sheet 3 can be completely peeled from the liner 1.

  When affixing to the skin, the pad 4 may be applied to the puncture portion while the small piece portion 2 is held between fingers, and the adhesive layer 31 portion of the liner 3 may be affixed to the skin around the puncture portion. At this time, the small piece portion 2 is also attached, but since the four corners of the sheet 3 including the corner on the small piece portion 2 side are attached to the skin, the small piece portion 2 is peeled off from the small piece portion 2 side over time. There is no fear of it. In addition, when it is desired to stick and fix the skin more firmly, the sheet 3 is stuck with the small piece part 2 attached, and then the small piece part 2 is peeled off from the sheet 3 and the whole sheet 3 is stuck. .

  If it is applied with the small piece portion 2 attached, it can be easily peeled off from the small piece portion 2 side after hemostasis, so that it can be easily peeled off, and there is no problem that it is difficult to peel off, which tends to occur in such adhesive bandages. Further, since the finger does not touch the adhesive layer 31 directly, it is hygienic.

  Even when the folding line 22 is provided, the small piece portion 2 is not separated from the liner 1 but when it is erected, the portion peeled off from the liner 1 of the sheet 3 is held between fingers, and the small piece portion 2 is the liner 1. It is also possible to leave only the sheet 3 and paste it. However, as described above, in consideration of sanitary problems, ease of sticking, and the like, a method of using the small piece portion 2 separately from the liner 1 is more preferable.

  FIG. 11 and FIG. 12 show another aspect of the small piece portion 2 of the hemostatic adhesive bandage of the present invention. In the case of FIG. 11, both the cut line 21 and the fold line 22 are constituted by straight lines. Moreover, the thing of FIG. 12 is formed so that the cut line 21 may draw an arc from the side part 11, and the folding line 22 is formed in the place where the two cut lines 21 meet. Among these modes, the one in FIG. 12 has a fold line 22 that is much shorter than those in the other modes, so that it is easier to separate the small piece portion 2 from the liner 1.

  As described above, the hemostatic bandage of the present invention can be easily peeled from the liner 1. Furthermore, when the cut line 21 and the fold line 22 are formed on a part of the liner 1, the finger does not touch the adhesive layer at the time of peeling, so that it is hygienic and easy to manufacture, and the raw material cost does not increase.

  In the hemostatic adhesive bandage of the present invention, as the material of the liner 1, a peeled paper, a resin sheet or the like can be appropriately employed. The sheet 3 can be appropriately selected from resin sheets, non-woven fabrics, cloths, papers, and the like, and non-woven fabrics and knitted fabrics having flexibility, stretchability, and air permeability are preferable. The pad 4 can be used by using non-woven fabric, cloth, cotton, compressed cotton, gauze, other liquid absorbency, or a combination thereof. In addition, as for the nonwoven fabric etc. which are used for the pad 4, what was sterilized as needed and what was impregnated with a disinfectant etc. may be used. The pressure-sensitive adhesive layer 31 is mainly formed of a rubber-based, acrylic-based, silicon-based, or polyvinyl alcohol-based pressure-sensitive adhesive, and various additives such as an antioxidant, a filler, a softener, a plasticizer, a pigment, and an ultraviolet absorber are appropriately added. An agent component and a transdermal drug can be contained.

  The bandage of the present invention is mainly intended for hemostasis after injection, but it goes without saying that the present invention can be used for other general bandages and patches.
