Embodiment Construction

[0012] In accordance with the present principles, high discharge rate battery technology is used to reduce defibrillator charging times by a factor of 8 or more. This results in a defibrillator capable of charging its capacitor in less than a second. Since the high discharge rate battery has a lower overall charge capacity, the high discharge rate battery can be supplemented with a standard discharge rate battery to provide long battery operating time for the defibrillator.

[0013] High discharge rate batteries enable extremely fast capacitor charge times. Several exemplary embodiments of a defibrillator having a high discharge rate battery combined with a high capacity battery. For pre-hospital use, a high discharge rate battery can be used to charge the capacitor, while a second battery with a high capacity cell is used to power other operations and provide longer run time. For hospital use where shorter runtimes are required, high discharge rate batteries can be used bot...

Abstract

A defibrillator includes a first battery (12) configured to provide a discharge rate to a capacitor suitable for generating a defibrillator shock. A power source (16) has a larger capacity than the first battery. A power control module (14) is coupled to the first battery and the power source and is configured to selectively enable connections between the first battery and the power source and from each of the first battery and the power source to the capacitor based on feedback from at least one of the first battery and the power source to reduce charge time.

Description

technical field [0001] The present disclosure relates to medical devices, and more particularly, to a rapid charge defibrillator. Background technique [0002] External defibrillators require a high degree of portability so that they can be quickly carried to a patient suffering from cardiac arrest to deliver a life-saving shock. Defibrillators typically operate on battery power. To deliver the shock, the defibrillator charges a capacitor to a high voltage, usually over 2000 volts. Due to the limitation in the discharge rate of the battery, it takes 5 to 8 seconds or more to charge the capacitor. After a cardiac arrest, the chance of survival drops by 10% to 15% every minute, and several shocks may be required to recover the patient. [0003] The discharge rate of a battery is specified as a fraction of capacity. Thus, a standard Li-ion battery cell designed for a capacity of 2200 mAh-hours and a maximum discharge rate capacity (1C) can supply a peak discharge current of...
