Abstract:
[Problem] Life-saving implements employing a buoyancy bag that is expanded by injecting compressed gas from a gas cylinder are limited in terms of the size to which the life-saving implement can be increased, and in terms of application to expansion of the buoyancy bag in the water. [Solution] A life-saving implement (11) in the shape of a grenade is equipped internally with a folded buoyancy ring (12), an inflater (13) coupled to an air injection opening thereof, an igniter (14), and an igniter switch (15) for activating the igniter. The igniter switch (15) is an application of a fuse of a shell or the like, and can be installed by selecting an igniter switch in which a proximity fuse is applied or in which a time limit fuse is applied.
