1: Market research: 1. There are many factors related to maritime accidents, and emergency rescue modes vary. The emergency rescue mission at sea is uncertain, and in the event of adverse weather and extreme weather, ships cannot go out to sea for search and rescue. Ships with strong wind and wave resistance have poor mobility, low search and rescue efficiency, and search and rescue aircraft have high requirements for climate conditions and pilots, with limited application environments. 2: Difficulty in search and rescue transportation. The location of drowning personnel is difficult to locate, and rescue personnel find it difficult to search and rescue. After a disaster occurs, the sea and climate conditions are generally harsh, making it difficult to salvage. The maritime disaster area is generally far from land, and transportation and transfer require a large amount of rescue forces and fast transfer tools. Problem discovered: 1: Low rescue efficiency. The ordinary rescue methods affect the time and efficiency of rescue operations. Traditional life jackets have low efficiency and miss the best rescue time. 2: The rescue function is single. The number of rescuers using traditional rescue rings and life jackets is limited, and only one trapped person can be rescued at a time. 3: Maritime accidents occur frequently. Maritime disasters occur frequently, and there is still no rational emergency rescue solution for maritime rescue issues.1: The fundamental difference between this product and traditional life jackets is that it breaks the limitations of "saving one person with one coat". After the air cushion is fully extended, it can bear the weight of four adults, achieving the breakthrough of "saving four people with one coat". 2: Invented inflatable bottles that can be recycled and replaced to avoid waste. 3: Added the design of emergency medicine supply packages, with 2 rescue supplies on each side of the rescue suit for disaster victims to use; There is also Beidou+GPS dual star positioning, with an accuracy of less than 3 meters. Equipped with life jacket lights and AIS alarm function. Assist ship drowning personnel in sending signals to rescue personnel. This product uses LED lights as the light source, making it convenient for close range rescue at night.The maritime distress stretchable rescue suit adheres to the design concept of "people-oriented", achieving a breakthrough of "saving four people with one suit" and using technology to protect lives. Invented inflatable bottles that can be recycled and replaced, avoiding waste. Our products serve society with revolutionary technology and excellent quality, benefiting humanity!
