The present invention relates to a necklace with a life-saving function. More specifically, it comprises: an expansion unit (1) which is worn on the neck of a wearer; a water pressure sensor (2) which is attached to the expansion unit so as to sense the water pressure; a controller (3) which determines and controls whether the life-saving function works according to the results sensed in the water pressure sensor; a compressed gas unit (4) which supplies gas to the expansion unit according to the result determined by the controller; and an injection unit (5) which injects gas to the compressed gas unit. According to the necklace with a life-saving function of the present invention, when a wearer is submerged under a certain water level, the water pressure sensor of the necklace detects it and the injection unit automatically injects gas into a life-saving unit (the expansion unit) to thereby operate the life-saving unit, thus preventing drowning accidents and enabling injection of the compressed gas and nightvision. |
