Defibrillator
First Claim
1. A defibrillation unit comprising:
- a defibrillator controller;
a capacitor unit capable of temporarily storing and discharging sufficient energy to deliver a defibrillation shock to a patient;
a shock delivery circuit for discharging the capacitor unit to deliver the defibrillation shock; and
a charging circuit that controls the transfer of energy from a power supply to the capacitor unit to facilitate charging the capacitor unit to a level suitable to facilitate the delivery of the defibrillation shock to the patient; and
wherein the defibrillator controller is configured to set a parameter of the charging circuit during use of the defibrillator unit to thereby help control a power supply draw current for the charging circuit, wherein the defibrillator controller is configured to set the parameter of the charging circuit based at least in part on a current delivery capability of the power supply to which the defibrillation unit is attached.

Abstract
Several defibrillators, defibrillator architectures, defibrillator components and methods of operating defibrillators are described. In one aspect, a defibrillator (as for example an automated external defibrillator) that can be powered by a mobile communication device such as a smart cellular phone or a tablet computer is described. Utilizing a phone (or other mobile communication device) as the power supply for an external defibrillator allows the external defibrillator to be smaller and, in some circumstance, removes the need for a battery that stores sufficient energy for shock delivery—which would need to be checked and/or replaced on a regular basis. Additionally, when desired, certain control functionality, computation, data processing, and user instructions can be handled/presented by the mobile communications device thereby further simplifying the defibrillator design and improving the user experience. This architecture takes advantage of the nearly ubiquitous availability of smart phones, tablet computers and other mobile communication devices.
