Today ( 6) 3:40 p.m. , the Chinese simulation of helium-oxygen saturation diving 480 meters successful experiment to create a 493 m deep dive record of your work in Asia . Flowers and applause, Li Gang, the Chinese navy divers , Ni Lei , Ye Yongli , Sun Zhijiang pressure experiments in saturation diving chamber after a 19-day work and life , safety and smooth out of the door .

China Radio Network reports, divers said Li Gang , 19 days in the cabin , their physical condition in general can , mainly by sleep problems and breathing resistance problems, the high-pressure environment, breathing more difficult. On the extravehicular feeling , the excited Li Gang said: "The body has special relaxation, breathing a bit boring on the feeling that this probably 7-15 days to return to the level for entrance to the former . "

Member of the CPC Central Committee Political Bureau , Shanghai Municipal Party Committee Secretary Yu Zhengsheng , the Central Military Commission , member of the Navy Navy Commander Wu Shengli , came in a Medical Research Institute , meet the heroes of divers emerged from the capsule .

CMC members , Navy Commander Wu Shengli said that the success of this experiment indicates that deep-sea diving techniques in the development of our country has achieved another important milestone achievements for the speeding up of our submarine rescue technology , improve the integrated maritime security system Have important and far-reaching significance.

Naval Medical Research Institute through a staff of four divers in the central nervous system function , physical, intellectual, psychological and emotional and breathing , pulse, blood pressure, body fluids and other aspects of the 14 indicators for continuous real-time monitoring of the physical indicators of the physiological normal .

Saturation diving is diving in a long time exposure under high pressure , dissolved within the body of inert gas to reach full saturation level. Is directly exposed to the deep sea diver , the conduct of underwater diving operations only way . The experiment using our own design and construction of 500 m saturation diving experiment equipment , the first saturated with self- study plus decompression program . Four divers were selected out of China through the layers of active duty Navy divers excellent .

Navy Diving Medical Research Institute of Medical Research Fellow , experimental project leader Xiao Weibing told reporters that the experiment and the equipment to withstand an absolute atmosphere of 49 , equivalent to more than 10 cm thick steel plate only afford the pressure on refining the experimental difficulties Is the compression and decompression program development .

Xiao Weibing said: "The depth of this limit has been entered into the area , divers will be under great pressure load , is manifested by the high pressure nervous syndrome would occur , in our experiment, divers Huoduohuoshao 's also all the performance Some symptoms, have a rational , scientific process pressure , and then a diver also needs a strong determination "

August 21 afternoon , high pressure JEM pressurized to 480 meters, 480 meters water depth equivalent of divers living cabin to stay up to 49 hours . During the four divers wearing helmets, wearing a diving suit , diving has sneaked into the patrol cabin, 493 meters of water in a simulated environment were removable flange , tighten the nut , moving heavy objects , running water, look for items such as deep diving operations .

Navy Diving Medical Research Institute of Medical Research Office side to group told reporters that the experimental success of the technological level of China's diving with a big leap in the deep future operational in China provides a theoretical support .

Side by group , said : " First, to improve our country's diving techniques; second, so we made a series of technical solutions for our offshore oil development , submarine rescue provided technical support; third , through research Made a series of new data , these effects on the human body , regardless of the further implementation of future operations at sea Ye Hao , to carry out future training Ye Hao , improve medical protection, provides a theoretical basis . "

The significance of saturation diving : dive deeper , longer and longer ,

The concept of saturation diving diving physiologists from the U.S. Navy in 1957, Bond proposed that divers exposed to long hours under high pressure , body fluid in tissues dissolved in the inert gas to reach full saturation level , that is out of the body of the inert gases Balanced. Zai no deep diving device cases, saturation diving with dive Shen Duda , Zuoyeshijian Chang , Gongzuoxiaolv higher characteristic , is the direct Bao Lu Shijie on Baozhang divers to carry out underwater operations in high-pressure environment of the only dive Fang Shi , widely used On submarine rescue , submarine construction and operations , underwater exploration , marine scientific investigation and other fields. At present, the United States, Britain , France, Japan and some other countries have carried out research work in France in 1992 to create simulation of the experimental saturation diving depth of 701 meters world record of most of Japan in 2008 to create operational saturation diving 440 meters , 450 submarine patrol Meter records the deepest in Asia . Naval Medical Research Institute of the experiment , the depth of 480 meters in the simulation data obtained and accumulated experience, our saturation diving technology will break new ground , to protect deep sea diving helium-oxygen saturation to provide strong support .
