Abstract
The disclosed systems and methods provide a mobile defibrillator system that can include a mobile defibrillator (AED) unit configured to operatively connect to a device capable of running an application. The mobile AED unit can include circuitry for administering an electric shock to a subject; and one or more pads. Each pad can include one or more needles electrically connected to the circuitry and can be configured to pierce skin of the subject; reside within the subject; and deliver current from the electrical shock to the subject.
Claims20
A mobile defibrillator system comprising:
- a mobile defibrillator (AED) unit configured to operatively connect to a device capable of running an application and operating as a power source for the mobile AED, the mobile AED unit comprising:
- circuitry for administering an electric shock to a subject, the circuitry comprising a charge controller, a sense line bias circuit, a current sense resistor, a switch, a transformer, and a capacitor;
- and
- one or more pads configured to adhere to the subject for administering the electrical shock.
A method for operating a mobile defibrillator system, the method comprising:
- connecting a mobile AED unit to a device capable of running an application and operating as a power source for the mobile AED;
- controlling, by a charge controller, a sense line bias circuit of circuitry within the mobile AED unit;
- monitoring, by a current sense resistor, a current flowing through a switch and a transformer of the circuitry;
- charging a capacitor of the circuitry;
- and
- administering an electrical shock to a subject by one or more pads;
- wherein charging the capacitor comprises:
- switching the switch on to flow current through the transformer;
- shutting off the switch in response to the current sense resistor measuring a voltage above a predefined threshold;
- and
- transferring energy stored in the transformer to the capacitor.
