ABSTRACT:
An exemplary embodiment comprises a metering device which can be worn on the body or which is preferably implantable in the body, the metering device exhibiting a delivery unit for the dosed delivery of the fluid from a supply container to a discharge aperture of a catheter and also exhibiting an appertaining operating circuit, and an external control and programming device. The operating circuit in the metering device and the control circuit in the control device can be inductively coupled for operational signal transmission, to which end at least one transmission coil is present in the control device and at least one reception coil is present in the metering device. Given implanted devices, it is the object of the disclosure to guarantee the highest degree of patient security. For function monitoring of operating parameters of the metering device the metering device exhibits a transmitter whose signals can be received in a receiver outside of the patient's body and, under certain conditions, can be evaluated. In addition to pure function monitoring, an acknowledgement of signals as well as an answerback of the value of one or more operating parameters is possible.
