ABSTRACT:
An adhesive plate with an indicator function, and an indicator therefor, according to one embodiment the adhesive plate being comprised of a hydrophilic composition containing a water-soluble coloring matter such as a food color, a dye, a pigment, or metallic salt applied onto or embedded in a part or the whole of a peripheral region of the plate spaced apart from the center thereof, the water-soluble coloring matter being dissolvable in liquid excrements or exudates so as to change color and provide visible indication of the end of the usable life of the adhesive plate. According to another embodiment, the adhesive plate can comprise a hydrophilic composition containing a color development agent applied onto or embedded in a part or the whole of a peripheral region of the plate spaced apart from the center, which, upon contact with liquid excrements or exudates, the hydrophilic composition containing the color development agent is dissolved therein and dropped into a receiving bag attached to the adhesive layer, to permit the color development agent to come into contact with, and react with a coloring reagent previously added to the bag, whereby the color of the color development agent and/or the coloring reagent is changed thereby indicating the limit of the useful life of the adhesive plate.
