Abstract
The present disclosure relates generally to a defibrillator assembly comprising a defibrillator having a first operating mode for delivering a high energy output to a patient and a second operating mode for monitoring the patient, a first battery unit operably coupled to the defibrillator, and a second battery unit operably coupled to the defibrillator. One of the first battery unit and the second battery unit provides power to the defibrillator during the second operating mode. Both the first battery unit and the second battery unit provide power to the defibrillator during the first operating mode.
Claims20
A method comprising:
- determining, by a controller of a defibrillator, a remaining charge of a first battery unit and a second battery unit of the defibrillator, wherein the defibrillator is configured to operate in a first operating mode for delivering a high energy output to a patient and a second operating mode for monitoring the patient;
- causing, by the controller, the defibrillator to use only one of the first battery unit and the second battery unit during the second operating mode;
- and
- causing, by the controller, the defibrillator to use both the first battery unit and the second battery unit during the first operating mode such that the first battery unit and the second battery unit provide power to the defibrillator proportional to their respective remaining charge during the first operating mode.
A method comprising:
- determining, by a controller of a medical device, a remaining charge of a first battery unit and a second battery unit of the medical device, wherein the medical device is configured to operate in a high power operating mode and a low power operating mode;
- causing, by the controller, the medical device to use only one of the first battery unit and the second battery unit during the low power operating mode;
- and
- causing, by the controller, the medical device to use both the first battery unit and the second battery unit during the high power operating mode such that the first battery unit and the second battery unit provide power to the medical device proportional to their respective remaining charge during the high power operating mode.
