Research of drowning autonomous rescue product based on swallowing monitoring

Abstract

To find a better self-rescue way for sudden drowning swimmers through the redesign of drowning self-rescue products. Based on the self-rescue needs of drowning patients and the design and evaluation criteria of product ergonomics, the situation analysis method was used to record, evaluate and summarize the physiological signs and behavioral characteristics of drowning patients. The causes and rules of changes in the characteristic physiological signs of "swallowing" of drowning patients were deeply studied, and the ways and methods of obtaining information about "swallowing" were explored. Experiments were conducted to verify the feasibility of the swallowing monitoring technology in the water environment. The results showed that there were significant differences in physiological signs of "swallowing" between drowning people and normal swimmers due to the behavior of "bucking", which were accurately identified by swallowing monitoring technology through the audio signals generated by the throat. It is proved that swallowing monitoring technology can be effectively applied to the design of drowning self-rescue products, which can improve the success rate of drowning self-rescue and reduce the occurrence of drowning accidents.
