EXTENSION INDICATORS

摘要

An extension indicator for determining a predetermined extension applied to an extensibly deformable article such as medical bandage used in compression therapy comprises first (420) and second (430) co-operating members, each adapted to be secured to an extensibly deformable article (440) in which one of said members is more extensible than the other and in which each member (420, 430) bears visual indication means (450, 460, 470) which, upon extension of the more extensible member, are adapted to align with each other to indicate a predetermined extension of the more extensible member.
