Abstract
A defibrillator (100) and method (300) are described having an improved automatic activation feature. The improvement comprises sensing a pattern of events which indicates that repeated activations are inadvertent, and thus are unnecessarily depleting the battery. The defibrillator then disables the automatic activation circuit (210) feature. Then, the sensing of a manual defibrillator operation may trigger a re-enablement of the automatic activation feature.
Claims18
A portable defibrillator apparatus comprising:
- an electrode connector;
- an operator actuated button;
- an automatic power on circuit operable to actuate the defibrillator independent of the operator actuated button in response to an activation input;
- and
- a controller in electrical communication with the electrode connector, the operator actuated button and the automatic power on circuit, the controller operable to detect a pattern of activation events and further operable to disable the automatic power on circuit in response to the detected pattern of activation events.
A portable dearillator apparatus comprising:
- an electrode connector;
- an operator actuated button;
- an automatic power on circuit operable to actuate the defibrillator independent of the operator actuated button in response to an activation input;
- and
- a controller in electrical communication with the electrode connector, the operator actuated button and the automatic power on circuit, the controller operable to detect a pattern of activation events and further operable to disable the automatic power on circuit in response to the detected pattern of activation events,
- wherein the automatic power on circuit further comprises a case opening sensor which actuates when a storage case for the defibrillator is opened.
A method for managing a power condition of a defibrillator, comprising the steps of:
- providing a defibrillator in a low power standby condition, the defibrillator including a controller in electrical communication with an electrode connector, an operator actuated button, and an automatic power on circuit operable to actuate the defibrillator independent of the operator actuated button in response to an activation input;
- automatically activating the defibrillator with the automatic power on circuit;
- detecting a pattern of events based on the automatically activating step;
- disabling the automatic power on circuit based on the detecting step;
- and
- returning the defibrillator to the low power standby condition with the automatic power on circuit disabled.
