A life-saving garment (1, 2, 3a, 3b, 34) is described, equipped with means adapted to instantaneously inflate an air chamber, to take back to the surface an apnea swimmer/swimmer in difficulty; such garment has an automatic device (20), for monitoring activities of the apnea swimmer and automatic aid, in case of need, wherein the device (20) comprises: a central unit (21), comprising a microprocessor (22), a timer (23) and one or more supply batteries (24); a peripheral input unit (25), comprising a pressure sensor (26), adapted to determinare the depth at which the apnea swimmer is; a peripheral output unit (28), comprising a valve (29) for entering gas into the air chamber (15, 16) of the inflatable garment (1, 2, 3a, 3b, 34), the valve (29) being connected to a small pressurised gas bottle; the device (20) activates the gas entry valve (29) when the immersion length exceeeds a preset time. |
