Method and medical device for reducing the effects of interference generated by a radio transmission from the medical device

A medical device comprising input modules for collecting an analog electric biological signal from a patient, processing modules connected to the input modules, and a transceiver section comprising a mobile data terminal connected to the processing modules, the transceiver section being configured to connect to a radio communication network and to transmit and receive signals by using a time-division-multiplexing transmission, and the processing modules being configured to:

• a) carry out an analog-to-digital conversion of sample the collected analog electric biological signal by sampling the collected analog electric biological signal, wherein each sample is taken from the collected analog electric biological signal and memorized;
• b) during the sampling of the collected analog electric biological signal, monitor when the radio time-division-multiplexing transmission of signals from the transceiver section is active;
• and
• c) when the status of said radio time-division-multiplexing transmission becomes active, prevent the sampling of the collected analog electric biological signal from being performed as long as the radio time-division-multiplexing transmission remains in said active status.

A method of processing in a medical device an electric biological signal, comprising:

• collecting from a patient an analog electric biological signal;
• sampling the collected electric biological signal with a sampling period T1, wherein within each sampling period T1, the sampling is performed for a predetermined sampling active time slot Ts1, with Ts1<T1;
• during the collected sampling of the electric biological signal, monitoring when a radio time-division-multiplexing transmission of signals from the medical device over a radio communication network is in an active status, the time-division-multiplexing transmission being performed in the active status according to a predetermined transmission period T2, wherein, within each transmission period T2, signal transmission from the medical device is active for a transmission active time slot Ts2, with Ts2<T2;
• when the status of the radio time-division-multiplexing transmission becomes active, preventing the collected sampling of the electric biological signal from being performed in the sampling active time slot Ts1 that occurs in the transmission active time slot Ts2.
