Drowning-preventing lifesaving device based on heart rate judgment and control method thereof

Abstract

The invention discloses a drowning-preventing lifesaving device based on heart rate judgment and a control method thereof, and relates to the technical field of water rescue. The lifesaving device comprises a lifesaving mechanism, a control mechanism for controlling the lifesaving mechanism to work and a battery for supplying energy; an air bottle and an airbag are installed in an outer shell witha waterproof function; an airbag opening is formed in the position, corresponding to the airbag, on the outer shell; high-pressure compressed gas or liquefied gas is stored in a gas cylinder; a ventvalve is arranged at the opening of the gas cylinder; the gas cylinder communicates with the airbag through a vent pipe to form a lifesaving mechanism; the outer shell is arranged in a form of being attached to the neck of a human body; and the battery is arranged in the outer shell. According to the device, sudden increase of heart rate is used as the basis for judging drowning, so that the device can better adapt to the actual physique condition of an individual, and is high in judgment accuracy and quick in response; and the airbag can be timely and automatically inflated and blown to generate buoyancy so as to support the head of a user out of the water surface, so normal; breathing of the user is guaranteed and the life safety of the user is further ensured.

Description

technical field [0001] The invention relates to the technical field of water rescue, in particular to a control method for an anti-drowning lifesaving device. Background technique [0002] Drowning is a condition in which a person is submerged in water or other liquid medium and suffers injury. Water or other liquids filling the respiratory tract and alveoli will cause hypoxia and asphyxia, and the water absorbed into the blood circulation will cause changes in blood osmotic pressure, electrolyte imbalance and tissue damage, which will cause respiratory arrest and cardiac arrest, resulting in death or irreversible damage to organs , Seriously affect the health and life safety of the drowning person. [0003] Although the existing anti-drowning devices can play a lifesaving role to a certain extent, there are still some deficiencies, such as not being suitable for infants and young children who have no autonomous rescue ability and difficult to play a better lifesaving role ...
