I went to the aquarium last weekend and just in time for the mermaid show. It may be that the mermaid has been swimming in the water for too long and lacks oxygen, and accidentally bumped into a large tropical fish, and other divers saw it and quickly fished her up, fortunately nothing major.
It is not easy to be a mermaid, soaking in the water all day long, not to mention, but also have a large lung capacity, and the lung capacity is not large enough to complete the performance. The ordinary diving equipment is more bulky, not to mention, it is not very good to look at when worn, and there is no ornamentation. Are there any smaller underwater breathing apparatus?
Artificial fish gills are small and can breathe freely underwater when worn
A designer in South Korea developed an artificial fish gill respirator, named Triton, which is also the world's first artificial fish gill respirator. The artificial gills are so small that the user can breathe freely on the ocean floor simply by biting into Triton's plastic seal. According to the designers, the design of the artificial fish gills was inspired by James Bond's circulating respirator in the 007 series of movies.
Artificial fish gills
Artificial fish gill breathing apparatus is not the same as ordinary diving equipment, it does not need oxygen cylinders to be able to extract oxygen from the water autonomously like the gills of fish. The reason is that it has a built-in fine vibration compressor and filter membrane, which can separate oxygen from the water and then release the water, which also makes this respirator have oxygen collection and manufacturing functions.
The microscopic vibrating compressor in the artificial gills is powered by a lithium battery that can support the user to swim for 45 minutes at full power at a maximum depth of 4.6 meters, but it takes 2 hours to fully charge.
Oxygen evolution is small and is still in the conceptual stage
Having said all that, can artificial fish gill respirators be purchased now? The answer is no. At present, this product is still in the concept stage, and there are still many problems that need to be solved.
The first is that it doesn't break down enough oxygen from the water. As a mammal, humans need much more oxygen than fish. The size of this artificial fish gill is indeed relatively small, but it is also this that limits its ability to extract oxygen from water.
Secondly, the long-term use of artificial fish gills may cause oxygen poisoning. The oxygen extracted from the water by artificial fish gills belongs to pure oxygen, and if people breathe pure oxygen for a long time, oxygen poisoning will occur. If you want to add nitrogen to pure oxygen proportionally, you also need a compression bottle, which is contrary to its small design concept.
Although it is only a concept product, it also provides ideas for the development of underwater respirators after that, and I believe that in today's rapid development of science and technology, underwater respirators will become more and more mature. Even if you can't dive, swimming more often is very beneficial to your body.
I usually like to go swimming, and I like to float on the water when there is no one in the swimming pool (I am afraid that others will see me when there are people). At that time, it felt very calm and decompressing. Recommend a few underwater sports watches and swimming goggles that I usually think are very good to use for everyone, and the pro-test will not step on the thunder!
