Description

Technical Field

[0001] The utility model relates to the field of swimming safety, in particular to a pool monitoring and alarm device. Background Art

[0002] A swimming pool is a special place for people to carry out swimming activities, where people can move or compete. Most swimming pools are built on the ground and can be divided into general swimming pools and warm water swimming pools according to water temperature, including indoor, outdoor, and private swimming pools. Private swimming pools are usually built in villas. With the continuous increase in the ownership of private swimming pools, it often happens that children drown due to poor parental supervision.

[0003] When a person sinks into the water facing death, they struggle desperately near the water surface first, usually only being able to rise and fall for about 1 to 3 minutes. After that, due to desperately opening the mouth to breathe, a large amount of water is inhaled, and the water is inadvertently sucked into the trachea. Choking on water and panic or trying to hold one's breath for a longer time cause the originally tense muscles of the whole body to become even more tense, reducing the body's buoyancy rapidly, and the body sinks deeper until it is submerged. After being submerged, the omnipresent water quickly blocks the trachea or fills the lungs within 1 minute, stopping the breathing function. If water continues to enter the lungs and seeps through the alveoli into the blood, it will continue to break the red blood cells in the blood. After a large number of red blood cells are damaged, the oxygen-carrying capacity deteriorates further. Under the successive hypoxia of the body's blood vessels, cells, organs, and tissues, finally, the cardiac muscle fibers in the heart cavity responsible for the heartbeat spasm and paralyze, causing the heart to stop beating. The above is the process of drowning death, usually within 5 minutes.

[0004] However, when a swimming pool is in use, there are usually dedicated lifeguards at public swimming pools to prevent accidents from occurring to users during swimming. For the sake of privacy during use, private swimming pools are not equipped with dedicated lifeguards, which also results in the inability to discover outsiders or children falling into the swimming pool in a timely manner. Therefore, we provide a swimming pool alarm. Summary of the Utility Model
