<p>A life-saving aid comprising an elongate inflatable tube (2) provided with an automatic inflation device (6) arranged to release CO2 gas to inflate the tube (2) when immersed in water or manually triggered. The tube (2) is compact when deflated, throwable, has significant tensile strength and is designed so that after inflation and use, gas may be readily excluded via oral inflation tube (7) by releasing the valve and rolling the tube (2) from distal end (4) toward proximal end (3). Hand holds (5) are provided together with fastening means (8 and 9) to enable the tube (2) to be formed into a loop after inflation.</p> |
