Embodiment Construction

[0016] Such as figure 1 , figure 2 As shown, a life-saving equipment includes an equipment main body 1 and an airbag 2 located on the front and rear surfaces of the main body and inflated into a capsule-shaped hull; the main body 1 is a vest-type design so that the main body 1 is worn on the user's body. There are fixed buckles on both sides of 1.

[0017] Such as image 3 As shown, the inflated airbag 2 forms two layers of airbags. A gap is provided between the outer airbags 21, and the inner airbags 22 are connected to each other by a fixing strip 221, and surround the user's body; the inner airbags 22 and The airbags 21 on the outer layer are connected by an inflatable column 23.

[0018] The surface of the outer airbag 21 is provided with a number of floats 3 to prevent the inflated airbag 2 from overturning.

[0019] Usually, the life-saving equipment can be worn on the user in the form of a vest; in case of a situation, the airbag 2 is inflated by high-pressure carbon dioxi...

Abstract

The invention discloses a piece of life saving equipment, comprising a main body and a gas bag; wherein, the gasbag, like a capsule ship hull after being inflated, is positioned on the front suface and the rear surface of the main body; the main body is worn by the user; two layers of gasbags are formed after the gasbag is inflated; a gap is positioned between the outer gasbags; the gasbags of the inner layer are connected with each other by a fixing strip, surrounding and covering the body of the user; the gasbag of the inner layer and the gasbag of the outer layer are connected by an inflation column. The life saving equipement has the advantages that a two-layer structure is formed after the gasbag is inflated; the inner layer enwraps user by the fixing strip; as a result, the inner part can be kept dry and proper heat preservation performance can be kept; a buoy positioned on the surface of the gasbag of the outer layer can prevent the inflated gasbag from overturning and realize the purpose of the invention; besides, the invention makes up for the deficiency of prior life jacket and avoids low body temperature caused by the immersion in water effectively.

Description

Technical field [0001] The invention relates to a life-saving equipment, in particular to a life-saving equipment used in water. Background technique [0002] What is the survival limit of a natural person in low-temperature waters (below 2°C)? This is the unsolved mystery of human body medicine in the world. The invisible killer of cold waters has swallowed the lives of countless maritime urgers. According to international maritime disaster statistics: nearly 10,000 shipwrecks occur every year in the world; thousands of fishing boats and cargo ships are sunk; hundreds of thousands of people died, of which 80% of those who fell into the water were frozen to death while wearing life jackets. [0003] A series of major shipwrecks caused the deaths of people falling into the water at low temperatures: On April 15, 1912, the giant luxury cruise ship "Titanic" collided with an iceberg in the North Atlantic waters near St. Johns, Newfoundland, Canada on its maiden voyage It sank in the...
