Wearable cardiac defibrillator system not delivering shock upon hearing preset delaying word from bystander

摘要

A wearable cardiac defibrillator (“WCD”) system may include a support structure that a patient can wear, an energy storage module that can store an electrical charge, and a discharge circuit that can discharge the electrical charge through the patient so as to shock him or her, while the patient is wearing the support structure. Embodiments may actively take into account bystanders, both to protect them from an inadvertent shock, and also to enlist their help. In some embodiments the WCD system includes a microphone that can sense when a bystander speaks a preset delaying word like “WAIT” or “NO”, and prevent the discharge.

主权项

1. A wearable cardiac defibrillator (WCD) system, comprising:
a support structure configured to be worn by a patient; an energy storage module configured to be coupled to the support structure and to store an electrical charge; a discharge circuit coupled to the energy storage module and controllable to discharge the stored electrical charge through the patient while the support structure is worn by the patient; a microphone configured to sense a sound that is ambient to the support structure while the support structure is worn by the patient; and a processor configured to control the discharge circuit to thus discharge the stored electrical charge, but control the discharge circuit to not thus discharge if the sensed ambient sound includes a preset delaying word.
