An automatically operating injection device with an occlusion alarm unit and a method for determining an injection occlusion are disclosed. The method includes generating a plurality of evaluation forces based on a series of force measurements and based on an evaluation time period; determining whether an occlusion exists based on either an evaluation of the plurality of evaluation forces or whether one or more of the series of force measurements exceeds a force threshold; and providing an injection occlusion alarm if an occlusion is determined to exist.

A system for transmission of medical data comprises a first device which is designed to be worn on the body of a patient and which generates medically relevant data when in operation, said data being transmitted wirelessly to a second device. The first device comprises a communication unit for the wireless communication with the second device, a circuit which generates medically relevant data when in operation and a handover memory for the intermediate storage of data that are to be transferred from the circuit to the communication unit or from the communication unit to the circuit. The data generating circuit is connected to the handover memory via a first data line and the communication unit is connected to the handover memory via a second data line. The first device comprises a change-over switch closing the first data line and interrupting the second data line in a first switched state and interrupting the first data line and closing the second data line in a second switched state, said change-over switch changing between the first and second switched state without communication with the data generating circuit.
