DEFIBRILLATION PROTECTION FOR MEDICAL EQUIPMENT SENSING CIRCUITS

Abstract: a medical apparatus includes a therapy component for performing a therapeutic procedure on the patient. the therapy component includes sensing circuitry for sensing electrical signals from one or more sensing electrodes of the therapy component that are placed on and/or in the patient. with the medical apparatus powered on, a determination is made as to when the therapy component is actively engaged in performing the therapeutic procedure on the patient. when the therapy component is actively engaged in performing the therapeutic procedure on the patient, the one or more sensing electrodes of the therapy component are electrically connected to the sensing circuitry. when the therapy component is determined to not be actively engaged in performing the therapeutic procedure on the patient, the one or more sensing electrodes of the therapy component are electrically isolated from the sensing circuitry.
