Description

  TECHNICAL FIELD The present invention relates to a sheet of adhesive bandage in which a plurality of adhesive bandages are spread on a release sheet and a laminate of adhesive bandages in which a plurality of adhesive bandages are laminated, and in particular, a sheet of a medical bandage suitable for protecting a puncture portion by an injection needle. The present invention relates to a body and a laminate.

  Adhesive plasters are used to prevent loss of body fluids and infection by sticking to wounds such as punctures, cuts, and punctures with injection needles. As this type of adhesive bandage, there is an adhesive that positively treats with a drug. For example, Patent Document 1 discloses a drug in the central region of the surface on the side of the pressure-sensitive adhesive layer of a base material layer provided with a pressure-sensitive adhesive layer on one side. Adhesive bandages have been proposed in which layers are bonded and the exposed surfaces of these pressure-sensitive adhesive layer and drug layer are covered with a release sheet. This adhesive bandage is an independent type for each sheet. The adhesive bandage is used by bringing a drug layer into contact with a wound and attaching an adhesive layer to the surrounding skin.

  Aside from such an independent type of adhesive bandage, the puncture part is temporarily temporarily protected until a relatively small wound such as a puncture part by an injection needle during blood collection or vaccination is closed. As shown in FIG. 10 (1), a simple structure in which an adhesive layer 102 is provided on the entire surface of one side of the base material layer 101 is used as a small adhesive bandage for this purpose. As shown in FIG. 10 (2), the edge of the adhesive plaster 100, which is generally supplied as a sheet body in which a plurality of sheets are spread on a large release sheet 103, is attached to the release sheet 103, is peeled off with a fingertip. After being raised from the sheath 103, it is picked and peeled off one by one and attached to the required part for use.

  This sheet body can be manufactured by laminating a base sheet provided with a pressure-sensitive adhesive layer on all one side with a release sheet, and then cutting the base sheet into a predetermined size without cutting the release sheet.

Utility Model Registration No. 3066873

  However, each of the conventional adhesive bandages 100 made into the sheet body described above is provided with the adhesive layer 102 on the entire surface (the entire peripheral edge) on one side of the base material layer 101. The entire peripheral edge on the side is stuck on the release sheet 103, and it is difficult to peel the adhesive plaster 100 from the release sheet 103 one by one with a fingertip, and the workability is extremely poor.

  Further, when the adhesive bandage 100 is peeled off from the release sheet 103, it is necessary to pick up the adhesive layer 102 at the peripheral edge with the fingertip, so that various germs or the like attached to the fingertip may be transferred to the adhesive layer 102 or infected. There is also a danger of being unsanitary.

  Furthermore, when the pasted adhesive plaster 100 is peeled off from the skin and removed, the adhesive layer at the periphery of the base material layer 101 becomes black and tends to remain on the skin side, and the adhesive plaster 100 cannot be removed cleanly.

  The object of the present invention is to make it possible to easily peel the adhesive bandages one by one and to use the adhesive bandages in a sanitary manner in a sheet of a medical adhesive bandage in which a plurality of adhesive bandages are spread on a release sheet. Is to make it.

  Another object of the present invention is to provide a new type of medical bandage that has never been seen before.

  As a result of intensive research to achieve the above object, the present inventor provided a non-adhesive portion at the peripheral portion of the adhesive bandage, and the adhesive bandage was removed from the release sheet as a pinch allowance that can be picked with a fingertip. It was found that the adhesive bandage can be easily peeled one by one if peeled off, and the fingertips can be prevented from coming into contact with the pressure-sensitive adhesive layer and used hygienically. That is, the present invention is a sheet body of adhesive bandage in which a plurality of adhesive bandages are stuck on a release sheet, and the adhesive bandage is inward from the periphery on one side of a base material layer provided with an adhesive layer on one side. The present invention relates to an adhesive bandage sheet characterized by having an extended non-adhesive portion.

  Further, the present invention is a laminate of adhesive bandages in which a plurality of adhesive bandages are laminated, and the adhesive bandage is a non-adhesive that extends inwardly from the periphery on one side of a base material layer provided with an adhesive layer on one side. It is based on the laminated body of the adhesive plaster characterized by the part being provided.

  In these sheet bodies and laminates of the present invention, when the non-adhesive part is provided along the entire peripheral edge on one side of the base layer of the adhesive bandage, the non-adhesive part can be easily picked with a fingertip from any direction. The adhesive bandage can be peeled from the release sheet or the underlying bandage one by one.

  Moreover, in the sheet | seat body and laminated body of this invention, you may make it provide an antimicrobial effect to a non-adhesion part. For example, by using an antibacterial sheet as the base material layer, leaving the peripheral part on one side, and providing an adhesive layer, and making the exposed surface of the antibacterial sheet (base material layer) a non-adhesive part An antibacterial action can be imparted to the non-adhesive part. Thus, in the present invention, when an antibacterial action is imparted to the non-adhesive part of the adhesive bandage, it can be used more hygienically even if the fingertip contacts the non-adhesive part.

  According to the present invention, the adhesive bandage can be easily peeled one by one and used, so that the work efficiency can be improved and the bandage can be used hygienically.

  Further, according to the present invention, the adhesive layer can be hardly left on the skin when the adhesive bandage after use is peeled off from the skin.

  Hereinafter, in order to clarify the features of the present invention, embodiments of the present invention will be described with reference to the drawings.
