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: A non-transitory computer-readable medium has recorded thereon a program that makes circuitry of a portable information terminal execute: a detection step of detecting presence/absence of an automated external defibrillator in an activated state based on presence/absence of a wireless signal sent from the automated external defibrillator, the wireless signal becoming detectable in response to activation of the automated external defibrillator having a wireless communication module; and a first transmission step of transmitting notification information for notification about the activation of the automated external defibrillator to a management computer in response to the automated external defibrillator in the activated state being detected in the detection step.

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.

Abstract: A disposable electrode includes: an electrode pad; and a connector, connecting the electrode pad to a defibrillator, and including an information holder that can be provided with a transmissive opening or a light reflective member, the information holder holding information about at least an expiration date, depending on presence or absence of the transmissive opening or the light reflective member, the information holder allowing the information to be notified from the defibrillator when the connector is connected to the defibrillator.

Abstract: A seal device where, even if a fluid to be sealed is under high pressure, a seal surface of a seal ring is prevented from producing heat and the seal surface is prevented from wearing.
