Abstract
Abstract The repository probe or drug dispenser consists of a tube which is divided into a probe head and a probe end part. In addition, a series of medicine carriers are disposed in the probe head which contain active ingredients and which have an axial length of at most three times the outside diameter of the tube. In addition, openings are provided in the tube transversely of each medicine carrier for the passage of fluids. Joint zones are provided between the segments of the tube in which the medicine carriers are placed. Because of the limitation on the axial length of the medicine carriers and the joint zones, the flexibility of the probe head between the relatively stiff medicine carriers is increased without distortion or a closing of the openings to the medicine carriers when deflecting the probe.
