Description

  The present invention relates to a bandage for hemostasis for covering and protecting a puncture part after intravenous injection, subcutaneous injection, blood collection, drip, etc. and a method for producing the same, and more particularly, it can be easily peeled off from a release paper at the time of use. The present invention relates to an adhesive bandage for hemostasis, which is easy to be applied, and has less materials and waste materials during production, and a method for producing the same.

  Conventionally, after treatment such as intravenous injection, subcutaneous injection, blood sampling, infusion, etc., in order to prevent infection, disinfecting cotton or disinfecting gauze was applied to the puncture site and pressed by hand for a while. A simple treatment method has been used by applying a small bandage with a pad at the center of the puncture site.

  However, since this adhesive bandage was affixed on the release sheet as it was, it was difficult to peel off, and the adhesive surfaces sometimes adhered to each other when peeled off, resulting in difficulty in handling.

  As a bandage for hemostasis with improved handling properties, a pad material that protects the puncture part is placed on the adhesive layer of the adhesive sheet, and this is covered with release paper, and the release paper piece folded in half is attached to the adhesive sheet. What was interposed between release papers was known (patent document 1).

  When using this bandage for hemostasis, the adhesive sheet can be peeled off from the release paper by pinching the release paper piece folded in half with a finger (Fig. 8). Since it is formed inside the edge of the tape or so as to coincide with the edge of the adhesive tape, it is difficult to hold with a finger, and the fingertip touches the puncture part when peeling the release paper There was a fear and there was a hygiene problem. Furthermore, there is room for improvement in the feeling of use of the adhesive bandage for hemostasis that the release paper is difficult to pick after being applied to the skin.

  In addition, the conventional manufacturing method includes a step of feeding an adhesive tape (bonding a support and an adhesive base) (adhesive tape feeding step), a step of bonding a pad to the adhesive tape, and a step of punching (pad bonding step) ), A step of bonding release paper and adhesive tape (release paper bonding step), and a step of punching the shape of the preparation with a cutter after the bonding step (preparation punching step). It was.

  That is, in such a conventional manufacturing method, in order to properly maintain the bonding position of the pad and release paper to be bonded to the adhesive tape, and in order to prevent generation of defective products due to the shift of the punching position of the preparation in the preparation punching process. In addition, a concave guide was installed on the production line, and the position in the direction perpendicular to the line flow direction of the adhesive tape was fixed. However, since a slight deviation occurs in the position due to the characteristics of the machine, as shown in FIGS. 7A and 7B, the adhesive tape 31 has a width of 1 mm to 5 mm at both ends than the punching width. A margin X was necessary. As a result, after punching, the portions of 2 mm to 10 mm were wasted on both sides, and the remaining adhesive tape after punching was discarded (FIG. 7C).

  Similarly, for the release sheet, when the release sheet is bonded to the adhesive tape, a margin of 1 mm to 5 mm is required from the adhesive tape in order to cope with the shift of the position of the adhesive tape in the vertical direction with respect to the production line. there were. For this reason, the remaining release paper after the punching of the preparation has been discarded in the same manner as the rest of the adhesive tape.

  As described above, there has been a demand for a reduction in cost and a reduction in the amount of discarded materials by reducing the discard amount of the remaining part of the adhesive tape, release paper, and the like generated after the preparation punching process.

  Furthermore, as the release paper piece 13 and the release paper 14 of the hemostatic bandage 1 of the present invention, conventionally used ones such as a resin sheet can be appropriately employed in addition to the release-treated paper.

  Hereafter, the manufacturing method of the adhesive bandage 1 for hemostasis of this invention is demonstrated with FIG. FIG. 2 (a) is a plan view showing a state before the hemostatic bandage of the present invention is punched with a cutter, and FIG. 2 (b) is a cross-sectional view showing a state before the hemostatic bandage of the present invention is punched with a cutter. FIG. 2 (c) is a sectional view showing a state after the hemostatic adhesive bandage of the present invention is punched out with a cutter.

  As shown in FIG. 3, the method for producing the hemostatic adhesive bandage 1 of the present invention includes a step 101 for feeding the adhesive tape 11, a step 102 for pasting and punching the pad 12 on the adhesive tape 11, a release paper piece 13, a release paper 14, A process 103 for bonding the adhesive tape 11, a process 104 for punching the shape of the preparation with the cutter after the bonding, and the series of processes is performed on the same production line, A means 201 for adjusting the position in the vertical direction is provided. Further, after these steps, there is a step 105 for individually co-sealing the hemostatic bandage 1.

  The steps will be described in more detail. First, in the punching process 102, the pad 12 is punched out in a circular shape from the band-shaped material, and in the bonding process 102, the pad 12 is attached to the center of the adhesive tape 11 with a gap. Next, in the bonding step 103, the band-shaped release paper piece 13 folded in half is bonded to the adhesive surface of the adhesive tape 11 so that the bent portion 13b is in contact with or close to the pad 12. At this time, the lower end 13c of the piece bonded to the adhesive tape 11 is stuck so as to slightly protrude from the end 11a of the adhesive tape 11 (FIG. 2b), but the lower end 13c of the release paper piece 13 does not necessarily protrude. It is not necessary to provide it, and at least the pressure-sensitive adhesive surface on the end 11a side may be covered with the release paper piece 13.

  Next, in the bonding step 103, the strip-shaped release paper 14 is bonded so as to cover the remaining surface of the adhesive tape 11 and the part of the release paper piece 13 that is folded in half. In this embodiment, the end 14a on the side of the release paper piece 13 is affixed so as to coincide with the end 11a of the adhesive tape 11 (FIG. 2b). You may provide so that it may set back suitably inside the edge part 11a.

  Next, each member bonded in the above process is punched into a drug product shape along the punching line 10 in the drug product punching process 104. At this time, as shown in FIG. 2B, a margin X is required between the uppermost part 10 a of the punching line 10 and the end of the adhesive tape 11. However, the end 11a on the opposite side protrudes beyond the width of the adhesive tape 11 to the side of the release paper piece 13 so that the punching line 10 forms the knob 13a, so that the end of the release paper piece 13 is cut off. There is no need to cut the adhesive tape 11 at the end 11a, and therefore there is no need to make a margin X. Thereby, the usage-amount can be reduced about the adhesive tape of width 1mm-5mm at least one margin among the margins of the both ends of the adhesive tape conventionally required. Furthermore, since the end 11a is provided to be located on the inner side within a range of 0 mm to 2 mm from the conventional adhesive tape punched out in a circular shape, the adhesive has a width of 1 mm to 7 mm in total at the end 11 a side. The amount of tape 11 used can be reduced.

  Moreover, in the manufacturing method of the adhesive bandage 1 for hemostasis of this invention, the means 201 which adjusts the position to the direction perpendicular | vertical with respect to the line flow direction of the adhesive tape 11 is provided. By this means, it becomes possible to alleviate the deviation of the adhesive tape 11 due to the characteristics of the machine. For example, the positional relationship between the end portion 13c on the adhesive tape 11 side of the release paper piece 13 and the end portion 11a of the adhesive tape can be accurately determined. It becomes possible to manage, and as described above, the remaining amount of waste generated after punching out the adhesive bandage can also be reduced. Moreover, it is possible to prevent the adhesive from protruding due to the above-described deviation.

  As an example of such position adjusting means, as shown in FIGS. 4A and 4B, an apparatus including a sensor 203, a control device 202, an actuator 201a, a bearing 201b, a roller 201c, a concave guide 201d, and a support portion 201e. Can be used. More specifically, a roller 201c is rotatably mounted between a pair of support portions 201e that are suspended in parallel on both sides of the production line, and the adhesive tape 11 can be guided inside the support portion 201e together with the rollers 201c. A concave guide 201d that forms a concave portion is provided. Furthermore, an actuator 201a for moving each of the above members in a direction perpendicular to the flow direction of the adhesive tape 11 is provided on the side surface of one support portion 201e. In addition, it is possible to smoothly move the line by providing a bearing 201b at a shaft attachment portion of the roller 201c with respect to the support portion 201e.

  Then, a sensor 203 for detecting the position in the direction perpendicular to the flow direction of the adhesive tape 11 is installed immediately after the release paper laminating step 103, and the end 13c of the release paper piece 13 and the end of the adhesive tape 11 are detected by the sensor. 11a is read, the deviation is transmitted to the control device 202, converted into a signal by the control device 202, and a signal is sent to the actuator 201a so that the position adjusting means 201 can be pasted without any deviation. After receiving a signal from the control device 202, the actuator 201a applies a force to the concave guide 201d provided with the roller 201c so as to be perpendicular to the traveling direction of the production line, and moves the entire concave guide 201d, thereby moving these ends. Misalignment can be prevented.

  The shape of the hemostatic adhesive bandage 1 of the present invention can be changed to various shapes (FIG. 5) such as a balloon shape, a round shape, and a square shape by changing the shape of the cutter in the preparation punching process 104. For example, when the cutter is a balloon-type blade, the knob 13 a can be formed on a part of the release paper piece 13. Therefore, the shape of the cutter in the preparation punching process is preferably a balloon type. Further, the shape and the protruding length of the knob portion 13a can be easily changed by changing the shape of the cutter for punching the preparation.

  Hereinafter, embodiments of the application of the adhesive bandage for hemostasis of the present invention will be specifically described. FIG. 6A shows a state in which the hemostatic adhesive bandage 1 of the present invention is individually packaged by the wrapping paper 2. When using the bandage 1 for hemostasis, open the wrapping paper 2 in advance, make preparations, and perform intravenous injection, subcutaneous injection, blood sampling, infusion, etc., with the needle inserted as follows: use.

  One side of the hemostatic adhesive bandage 1 is grasped and peeled off from the release paper 14 fixed to the wrapping paper (FIG. 6b). The hemostatic bandage 1 that has been peeled off is applied to the skin so that the pad 12 and the puncture portion overlap each other, and the hemostatic bandage body is fixed (FIG. 6c). Finally, the gripping portion 13a of the release paper piece 13 is grasped, and the release paper piece 13 is peeled off from the adhesive sheet 11 so that the puncture portion is covered and protected (FIG. 6d).

  In this way, if the wrapping paper is opened in advance, a series of operations can be performed with one hand, and the hand and the injection needle are stuck to the skin without touching the puncture portion while the needle is inserted. can do. Furthermore, after skin sticking, it becomes easy to peel by picking the release paper piece 13, and it is much easier to use than a conventional bandage for hemostasis.
