A performance tester of defibrillator accumulators for clinical purposes
Defibrillator battery life length depends on the way of the utilization of the defibrillator, the battery type and effectiveness of the defibrillator’s internal charging mechanism, as well as access of the personal. This paper describes the basics of energy discharging of the accumulator during the defibrillator clinical utilization. The main parameters and its monitoring are described as well. The methods of testing have been designed. The main part of this thesis describes the construction of the device for the testing of defibrillator’s accumulators and its use in the Department of medical devices in General faculty hospital in Prague. Several batteries were tested, the old an often used as well as the new batteries bought from the producer of the defibrillators. Based on the principles of lead-acid battery there is a predicted improvement in the acu-pack capacity while periodically being tested using our testing routine.
