Abstract:
1. A medical apparatus, comprising: at least one transport element configured to transport at least one fluid, said transport element being configured to be connected to a patient; a grounding device connected to the transport element; a selector designed to vary the effectiveness of the grounding device as a function of a leakage electrical current in at least one of the transport element and the patient wherein the selector comprises a first impedance and a second impedance having different values, the selector being effective to selectively connect a grounding line to the first impedance or the second impedance; a sensor connected to the selector and effective to emit a signal indicative of a leakage electrical current in at least one of the transport element and the patient; and a circuit configured to operate the selector as a function of the signal emitted by the sensor, wherein the circuit comprises:
