Patent ID: 8477026

Claim:
A medical data transmission system, comprising: a first device which is designed to be worn on a body by a patient and which generates medically relevant data when in operation, said data being transmitted to a second device in a wireless manner, whereby the first device comprises a communication unit for wireless communication with the second device, a circuit which, in operation, generates medically relevant data, and a handover memory for intermediate storage of data that are to be transmitted from the circuit to the communication unit or from the communication unit to the circuit, and whereby 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, characterized in that, the first device contains a changeover switch that closes the first data line and interrupts the second data line in a first switching state, and interrupts the first data line and closes the second data line in a second switching state, whereby the changeover switch switches between the first and the second switching state without communicating with the data-generating circuit.
