System for detecting and recording bioelectric signals, such as an electrocardiograph, electroencephalograph or the like, operating at radio frequency

摘要

System for detecting and recording bioelectric signals, such as an electrocardiograph, electroencephalograph or the like comprises a plurality of electrodes 3 that detect bioelectric signals in a patient 5. The signals are processed by a recording means 1 and printed on a magnetic, paper or similar support 28. Each electrode 3 comprises an ordinary transducer 9 that converts the signal detected in the body of the patient 5 into an electrical signal and is connected to modulator means 16 and radio frequency transmitters 12, which latter send the said electrical signal by radio to receiver means 21 and demodulator means 23 on the recording means 1, which latter receive all the radio signals emitted by the plurality of electrodes 3, convert them into electrical signals and send them to sampler means 24 which separate and divide up the various signals, the said sampler means 24 being connected to processor means 25 which cause tracing of a signal corresponding to the signal of a detected biological activity and record it on the support which is known per se, advantageously paper 28.
