[Ground-isolated input circuits of the electronic diagnostic apparatus as means of increasing electric safety of the patient].

Introduction into the medical practice of new diagnostic and therapeutic methods, such as electric stimulation, measurement of intracardiac blood pressure, of pH and others, entails possible hazards for the patient to suffer an electric current injury. To ensure the patient's safety during various disturbances in the operation of the devices certain protective measures have to be devised. On an example of the electrocardiograph possible methods of accomplishing complete isolation of the patient from the ground through separating the signal and supply circuits is shown.

[Protective measures against increase of the potential of a "grounded" passive electrode of the electrosurgical apparatus].

Causes accounting for the occurrence of high-frequency induced burns, one of the most common types of damage inflicted on patients during electrosurgical interventions, are considered. Different variants of circuits indicating the emergence of a leakage current passing to the ground via the patient's body when this comes in contact with a grounded object are analyzed. Recommendations for the protection of patients are listed.
