The invention relates to an elastic adhesive unidirectional bandage and to a method for the production and the use thereof. The inventive bandage is embodied in the form of a segment, exhibits elastic and adhesive properties and is designed, in particular for supporting joints and preventing and maximally reducing injuries in certain body regions. The bandage segment is held in position during a long time by means of the adhesive properties thereof and supports natural movements by the elasticity thereof without constrictions and folds. Even, when the bandage is carried for a long time, it does not provoke a foreign body feeling. The bandage segment is easily applicable and optimally anatomically adaptable by the specific design of the elastic areas (for example, only the partial areas of the segment are elastic) and by corresponding shape thereof.
1-16. (canceled)
A unidirectionally elastic bandage, adhesive on one side and used for supporting joints, characterized in that the bandage is embodied as a segment and has an elasticity of the backing layer in the range of 20% to 150%.
