Abstract
An example method includes charging, by a first circuit of a medical device, a capacitor by receiving a current from a single-use battery and discharging, by the first circuit of the medical device, an electrical shock to electrodes configured to be disposed on a subject. The example method further includes transmitting, by a second circuit of the medical device drawing a current from a rechargeable battery, a communication signal to an external device; and recharging, by the second circuit of the medical device, the rechargeable battery by receiving a current from a charging source.
Claims20
An automated external defibrillator (AED), comprising:
- a cartridge comprising:
- a single-use battery;
- and
- electrodes configured to be disposed on skin of a subject;
- a first circuit comprising:
- a discharge circuit comprising:
- an H-bridge configured to be electrically connected to the electrodes;
- and
- a capacitor configured to:
- charge by receiving a charging current from the single-use battery;
- and
- in response to charging, discharge an electrical shock to the electrodes via the H-bridge;
- a port configured to receive, from an external source, a recharging current from the external source;
- a second circuit comprising:
- a rechargeable battery electrically connected to the port and configured to charge by receiving the recharging current;
- and
- a transceiver powered by the rechargeable battery, the transceiver being configured to:
- transmit, to an external device, a communication signal indicating a status of the cartridge;
- and
- a housing enclosing the first circuit and the second circuit, the housing being configured to removably couple with the cartridge.
A medical device, comprising:
- a first circuit comprising:
- a discharge circuit comprising:
- a capacitor configured to:
- charge by receiving a current from a single-use battery;
- and
- in response to charging, discharge an electrical shock to electrodes configured to be disposed on a subject;
- and
- a second circuit comprising:
- a rechargeable battery;
- and
- an additional element powered by the rechargeable battery.
A method, comprising:
- charging, by a first circuit of a medical device, a capacitor by receiving a current from a single-use battery;
- in response to charging the capacitor, discharging, by the first circuit of the medical device, an electrical shock to electrodes configured to be disposed on a subject;
- transmitting, by a second circuit of the medical device drawing a current from a rechargeable battery, a communication signal to an external device;
- and
- recharging, by the second circuit of the medical device, the rechargeable battery by receiving a current from a charging source.
