ROLL TUBE / rescue tube

When a man falls into the sea, lifesaving should be carried out with tube.
However, when saving a life with tube, there are many difficulties because tube has limitation. So, ‘ROLL TUBE’ is suggested.
‘ROLL TUBE’ is a tube that is rolled as the tube is flat. If necessary, it can be picked out one by one and blew up with a simple act.
In addition, as it’s rolled unlike the ordinary tube, it is possible to save many lives rather than one life with this ‘ROLL TUBE’.
