Beschreibung
Zusammenfassung:	The system is fixed on an animal collar and allows a controlled release of chemical medication substances into a part of the animal. It is constituted by a tubular part having a flexible polymeric matrix layer containing the active substance. The length of the tube is adjustable so that the daily dose of the active substance is gauged to the weight of the animal. The ratio between the external surface of the tube and its wall thickness is as large as possible so as to eliminate linear procurement of the active substance. The tube can be associated with either a flexible or rigid support on the animal.
