Abstract: An automated external defibrillator includes: an operation accepter that accepts an operation input from a user; and a self-test executor that executes a self-test for checking a state of the automated external defibrillator when a first condition or a second condition has been satisfied. The first condition is that a setting time instant set in advance comes. The second condition is that the operation accepter accepts a predetermined operation input.

Abstract: An automated external defibrillator includes: a high voltage generator configured to charge or discharge electric energy for giving a subject an electric shock for defibrillation; an outer housing configured to house the high voltage generator and defining an exterior of the automated external defibrillator; and a potting material containing an insulating material. The high voltage generator includes: a high voltage circuit board; and a high voltage electronic component disposed on the high voltage circuit board. The potting material covers the high voltage circuit board and a terminal of the high voltage electronic component, and is in contact with the high voltage circuit board and the outer housing to fix the high voltage circuit board to the outer housing.

Abstract: An automated external defibrillator includes: a detector that detects an abnormality of the automated external defibrillator; and a notifier that notifies a user of the detection of the abnormality. The notifier has a display unit that includes a light source, and a sounder that generates an alert sound. The display unit executes a first mode and a second mode lower in power consumption alternately. The sounder executes a third mode and a fourth mode lower in power consumption alternately. At least a half part of each of periods in which the first mode is executed overlaps timewise with a corresponding one of periods in which the fourth mode is executed. At least a half part of each of periods in which the third mode is executed overlaps timewise with a corresponding one of periods in which the second mode is executed.

Abstract: A defibrillator includes: processing circuitry; and a memory storing a program. When executed on the processing circuitry, the program causes the processing circuitry to: calculate battery usage of a battery configured to supply power to the defibrillator; record, on a battery memory, information related to the battery usage; and record, on the battery memory, battery information indicating battery failure in response to voltage of the power supplied from the battery being below a threshold.

Abstract: An automated external defibrillator includes: a self-test executor that executes a self-test for checking a state of the automated external defibrillator; and a display unit that indicates the state of the automated external defibrillator. The display unit makes: a first display when the automated external defibrillator is in a normal state; a second display when the automated external defibrillator is in an abnormal state, and the first display and the second display simultaneously or in a predetermined pattern when the automated external defibrillator is self-testing.

Abstract: An automated external defibrillator (AED) includes: a battery configured to supply electric power to the AED; an indicator configured to visually provide predetermined information related to the AED and a remaining level of the battery; and an indicator controller configured to change a visual aspect of the indicator according to the remaining level.
