Method and medical device for reducing the effects of interference generated by a radio transmission from the medical device
First Claim
1. A method of processing in a medical device an electric biological signal collected from a patient, comprising:
- a) collecting from a patient an analog electric biological signal;
b) converting into digital the collected analog electric biological signal by sampling the collected analog electric biological signal, wherein a plurality of samples are taken from the collected analog electric biological signal and memorized;
c) during the sampling of the collected analog electric biological signal, monitoring when a radio time-division-multiplexing transmission of signals from the medical device over a radio communication network is active; and
d) when the status of said radio time-division-multiplexing transmission becomes active, preventing 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.

Abstract
A method of processing in a medical device an electric biological signal collected from a patient, includes: a) acquiring a plurality of samples from the electric biological signal according to a sampling process wherein each sample is taken from the electric biological signal and memorized; b) during the sampling process of a), monitoring an active/inactive status of a radio time-division-multiplexing transmission of signals from the medical device over a radio communication network; and, when the status of the radio time-division-multiplexing transmission becomes active, c) preventing in a) the acquisition of any of the plurality of samples, which according to the sampling process should be acquired during the active status of the radio time-division-multiplexing transmission, from being performed until the radio time-division-multiplexing transmission remains in the active status.
