Abstract
An apparatus includes two or more medical systems and a low impedance path. The two or more medical systems have respective electrical outputs and respective separate isolation grounds each isolated from power lines and from earth ground, wherein the two or more medical systems are electrically coupled one with the other via the patient. The low impedance path connects the separate isolation grounds of the medical systems to one another, causing one or more leakage currents to flow via the low impedance path instead of via the patient.
Claims9
An apparatus, comprising:
- two or more medical systems having respective electrical outputs and respective separate isolation grounds each isolated from power lines and from earth ground, wherein the two or more medical systems are adapted to be electrically coupled one with the other via a body of a patient;
- and
- a low impedance path that connects the separate isolation grounds of the medical systems to one another, wherein the low impedance path has an impedance that is lower than a predefined impedance associated with a human body and thereby causing one or more leakage currents to flow via the low impedance path instead of via the patient.
A method, comprising:
- providing two or more medical systems having respective electrical outputs and respective separate isolation grounds each isolated from power lines and from earth ground;
- electrically coupling the two or more medical systems with one another via a body of the patient;
- and
- connecting the separate isolation grounds of the medical systems to one another via a low impedance path, wherein the low impedance path has an impedance that is lower than a predefined impedance associated with a human body and thereby causing one or more leakage currents to flow via the low impedance path instead of via the patient.
