According to a third aspect of the present invention, the adhesive tape with medical scale according to the first or second aspect is characterized in that the release sheet is provided with a slit for forming a protruding piece for release.

In the adhesive tape with medical scale of the present invention, a scale for measuring an affected area, particularly preferably a grid scale and / or a circle scale, is provided on the upper surface or the lower surface of the adhesive tape base material by various printing methods. In addition, in this specification, the term "square grid and / or circular scale" is used to mean a square grid and a circular scale, and a square grid or a circular scale. In the above, when the grid graduation and the circular graduation are provided at the same time, it is preferable that the graduation scales are matched and the units are provided continuously. Further, as the circular scale, a plurality of scales can be provided concentrically. Further, in the adhesive tape with medical scale of the present invention, an adhesive layer is provided on the side where the adhesive tape base material is attached to the affected area. Further, the adhesive tape with a medical scale of the present invention is sterilized so as to be attached to the affected area.

The material of the adhesive tape base material is polyester,
Polyethylene, polypropylene, polyvinyl chloride, polycarbonate, polyurethane, polyimide, cellophane, etc. are used, but it is preferable that the adhesive tape base material has little expansion and contraction deformation from the viewpoint of dimensional accuracy of the size and shape of the affected area. Therefore, different kinds of materials can be laminated and used. In addition, the adhesive tape base material is preferably transparent as an optical property, and even if it is semitransparent, it can be used as long as it does not affect photographing. Further, it is preferable that the surface of the adhesive tape base material is matt-finished in order to prevent harmful reflection on the surface during photographing.

As for the color of the printing ink on the scale for measuring the affected area (square grid and / or circular scale, etc.), it is easy to see black or dark blue. For example, when the square grid and the circular scale are provided at the same time as described above, It is also possible to use only one of the grid scale and the circular scale by taking one of the two different colors and photographing through a color filter during use. Red ink is difficult to see when blood is attached to the affected area, so it is selected and used depending on the case. Further, the scale and the shape can be more surely grasped by additionally describing the scale numbers indicating the dimensions on the scale.

As the pressure-sensitive adhesive layer, rubber-based or acrylic-based ones can be used, and if necessary, tackifiers and auxiliary materials such as rosin-based, terpene-based, synthetic resin-based, phenol-based, xylene-based and the like. A softening agent, a filler, an anti-aging agent, and a cross-linking agent are used as the material. Solvent type, water type, hot melt type, etc. can be used for forming the pressure-sensitive adhesive layer, and the one that does not impair the transparency of the pressure-sensitive adhesive tape and has little skin irritation is used for selection. . Like the pressure-sensitive adhesive tape substrate, the pressure-sensitive adhesive layer is preferably transparent as an optical property, and can be used even if it is translucent as long as it does not affect photographing. When forming the adhesive layer,
If necessary, the adhesive tape substrate is subjected to a surface treatment such as corona discharge treatment or undercoat layer formation.

Further, when the adhesive tape with medical scale of the present invention is stored, a release layer of silicone polymer or the like is provided on the surface of the adhesive tape base material opposite to the adhesive layer, and is wound and sterilized. Alternatively, a method in which a release sheet such as a release paper or a release film coated with a release agent such as a silicone-based polymer is laminated with an adhesive layer and then sterilized and packed is used. To attach the adhesive tape with medical scale to the affected area in a stable manner, use the laminated release sheet as described above, and make a cut in the release sheet to form the projection for peeling. When the adhesive tape is attached, the release sheet side is faced to the affected area, and the adhesive tape with medical scale is bent into a V shape so that the release protrusion formed by the cut can be picked with fingers and the adhesive layer It can be carried out by adhering the central part of the to the affected area and then applying the adhesive to the whole while peeling off the release sheet. The affected area is recorded by photographing the above-mentioned state with a still camera or a video camera.

[0010]

The adhesive scale tape for medical use having the above structure has a scale for measuring the affected area (square scale and / or circular scale, etc.) on one surface of the adhesive tape substrate, and an adhesive layer is provided on the sticking side. Since it is provided and sterilized, it is hygienic, and at the same time, the adhesive layer of the graduated adhesive tape can be attached to the affected area, and the affected area can be photographed and recorded in this state.
