PROBLEM TO BE SOLVED: To provide a lifesaving bladder which is very cheap and has a simple configuration, in which an adult and a child can usually wear it without feeling discomfort and can swim while wearing it by suppressing buoyancy as much as possible, and further the buoyancy may act through an artificial operation in the case of emergency or when necessary to be able to breathe all the time while waiting for rescue.SOLUTION: A lifesaving bladder is constituted in such a way that a liquid bag 7 arranged in a bag body 1 is cut under an action of recovering force acted through a pulling action or a pressing action applied form outside the bag body or a releasing action of an energizing member kept under a latched state, and then buoyancy of the entire bag is increased with gas generated under reaction between reaction liquid 9 in the liquid bag and a foaming agent to cause a body of a wearing person to float. |
