Abstract

A patient data sensor device has an implantable patient data sensor and an implantable data transmission mechanism, which is in signal connection with the patient data sensor. The data transmission mechanism has an antenna for telemetric data transmission to an external data collection unit. In addition, the data transmission mechanism has a carrier plate for electronic components. The latter are covered on the carrier plate, at least to one side, by a cover. The antenna is configured in an edge region of the carrier plate and running around the latter and around the electronic components. The result is a patient data sensor device which is more tolerable for the patient.
