ABSTRACT:
A multilayer medical working means comprises at least two walls each made of a glass-clear, soft plastic, with one of the two walls being physiologically unobjectionable and the other wall or walls being a physiologically questionable wall provided with at least one physiologically questionable and/or untested additive. A full-area circumferential connection exists between the physiologically unobjectionable wall and the physiologically questionable wall. A softener gradient is provided between the walls of the working means in such a manner that the physiologically unobjectionable wall has a higher softener content than the physiologically questionable wall directly adjacent thereto which contains at least one physiologically questionable and/or untested additive. The position of the additive is kept constant in the adjacent physiologically questionable wall against the gradient pressure of the softener.
