Life jacket supporting breathing and water drinking functions

Abstract

The invention relates to a life jacket supporting breathing and water drinking functions. The life jacket comprises a face mask and a life jacket body; the face mask is equipped with an inhalation pipe, an exhalation pipe, a drinking water pipe and several fixed headbands; lifesaving boards in the life jacket body are formed by splicing of several life jacket modules; each life jacket module includes a shell, and a freshwater layer, a buoyancy material layer, a new air layer and a waste gas layer that are placed in the shell. The life jacket provided by the invention is made of non-metallic materials, does not cause secondary damage, is low in manufacturing cost, and no unnecessary weight increase. All the pipes and connecting pieces adopt medical plastic products, thus minimizing weight and operation difficulty. In addition, by wearing the life jacket, in the circumstance of a water accident, non-swimmers are free of panic caused by breathing difficulty after water inrush to mouths and noses, and cannot be choked with water or drowning, as long as a user holds a pressure balloon above water, continuous fresh air supply can be obtained, thus striving for precious opportunities forfollow-up rescue.

Description

technical field [0001] The invention relates to the field of lifesaving equipment, in particular to a lifejacket supporting breathing and drinking functions. Background technique [0002] At present, the lifejacket device is generally made of low-density buoyancy material or an inflatable structure as the main structure. Among them, lifejackets commonly used on ships mainly use low-density buoyancy materials, typically natural fibers (kapok, cork, etc.) and foam plastics (polyvinyl chloride, polystyrene, polyurethane, polyethylene, etc.). A lifejacket with an inflatable structure, typically a lifejacket in an aircraft cabin. In fact, when small and medium-sized cruise ships on the water encounter storms or special failures, there is a risk of capsizing, often causing heavy casualties. It is worth noting that many of them were killed despite wearing life jackets. One of the important reasons has two aspects: First, the capsized hull makes the personnel confined in the loca...

In fact, when small and medium cruise ships encounter storms or special failures on the water, there is a risk of capsizing, often causing heavy casualties

It is worth noting that many of them were killed despite wearing life jackets

One of the important reasons has two aspects: First, the capsized hull makes the personnel confined in the local water-filled space, and it is difficult for people who can swim to escape; secondly, the current life jackets have certain requirements for personnel and the use environment. , People who cannot swim, even if they are wearing a life jacket, may still be in danger of choking on water when it is difficult to control their body posture
