It relates to a lifesaving tube launcher that can be usefully used for lifesaving in case of a distress accident by saving lives by doing so and in particular, by greatly increasing the firing distance.

In general, a life-saving device such as a life-saving tube filled with air is used for lifesaving in the case of leisure activities, fishing work, and water play on water or the sea.

These life-saving devices are used to rescue the survivors by throwing the life-saving devices around the people in distress. It is not easy to throw a life tube from this secured throwing position to a point of distress far away, so there is a limit to life-saving activities.

In addition, when a distress occurs at sea, the more time passes after the accident, the further away from the point of distress due to the influence of flow velocity or current, etc. Without rescue equipment, it is impossible to quickly approach the survivors, and in particular, when the weather is bad, there are many difficulties in the rescue operation.

As a way to solve this problem, a technology to save lives by launching a life tube as a propulsion means to the vicinity of a drowning person and causing the life tube to expand has been devised and disclosed as Patent Nos. 1064610, 1174621, 1526908, etc. there is.
