Device for monitoring biological signals from patients, while an electro-surgical appliance is being simultaneously used |
摘要 |
The present invention relates to a system for use in monitoring a biological signal from a patient while an electro-surgical appliance which applies a high r.f. voltage, is being simultaneously used. The signals from a number of transducers are transmitted to an amplifier preferably an ECG amplifier with an input-filter. The amplifier is situated in a Faraday cage which is connected to one of the transducers. The filter is a screened HF-filter and the filter together with the Faraday cage is enclosed in an earth connected grounded container or screen. As a result radiation from the Faraday cage is substantially eliminated.
