An X-ray detectable adhesive bandage includes: an adhesive protective member further including a substrate and an adhesive layer; and an absorbent member formed by layering, in order from bottom to top, at a prescribed site upon the adhesive protective member, a metallic foil further including a hot melt bonding agent layer, a long object which is formed by an X-ray detectable material being covered either in whole or in part by a covering object, and an absorbent pad. The absorbent member is configured from a prescribed metallic foil, a prescribed long object, and an absorbent pad such as a heat bonding layered body.

X-ray detectable adhesive bandage and method of manufacturing X-ray detectable adhesive bandage

A medical pressure-sensitive adhesive sheet includes a urethane substrate, an interlayer adhesive layer, an olefin nonwoven fabric, and a pressure-sensitive adhesive layer for pasting in order and has a moisture permeability amount of 2000 g/(m&#xb7;24 hours) or more, or the like. In the medical pressure-sensitive adhesive sheet, a thickness of the urethane substrate is a value within the range of from 1 to 10 &#x3bc;m, a thickness of the interlayer adhesive layer is a value within the range of from 5 to 30 &#x3bc;m, the olefin nonwoven fabric is constituted with a polypropylene-based thermoplastic elastomer and has a maximum point elongation percentage of a value of 200% or more in the longitudinal direction and the transverse direction, respectively, and a thickness of the pressure-sensitive adhesive layer for pasting is a value within the range of from 5 to 45 &#x3bc;m.

A medical laminated body with a releasing member, has a medical sticking member having a sequentially laminated base material and a pressure-sensitive adhesive layer. It further has a releasing member laminated on a side of the medical sticking member that is provided with the pressure-sensitive adhesive layer, and a repositionable pressure-sensitive adhesive layer formed as a part of the releasing member at a side of the releasing member distal from the medical sticking member. A ratio represented by A2/A1 is in a range of 8 to 100 where Al is an adhesion of the repositionable pressure-sensitive adhesive layer in accordance with JIS-Z-0237 and A2 is an adhesion of the pressure-sensitive adhesive layer in accordance with JIS-Z-0237. Al is in the range of 10 to 150 g/25 mm, and A2 is in the range of 250 to 1,000 g/25 mm.
