Liquid absorbing device e.g. bandage, for child, has colored flexible strip intended to move relative to scale under effect of swelling of swelling element, so as to allow determination of rate of swelling of swelling element

摘要

The device (1) has a swelling element (2) intended to increase in volume by absorption and/or modification of its internal properties. An indicator unit indicates a swelling rate of the swelling element. The indicator unit includes a colored flexible strip (3) and a scale (4), where the colored flexible strip is intended to move relative to the scale under the effect of swelling of the swelling element, so as to allow the determination of the rate of swelling of the swelling element. The swelling element is swellable by absorption of a fluid. An independent claim is also included for a method for determining the degree of swelling of the swelling element.
