Abstract
A device for administering a substance, e.g. a medicament or a therapeutic agent, at a controllable administration rate, wherein the device includes a housing with a drive receptacle area for a drive unit, a substance receiving region to hold a substance container and an arrangement for hydraulic power transmission, which does not contribute to controlling the administration rate, located between the drive receptacle area and the substance receiving region, whereby the administration rate is controlled exclusively by the drive unit.
