God nine sets with five kinds
?In accordance with the Temple One arrangement with Shenzhou manned rendezvous and 9 docking mission plan, astronauts in orbit life of 13 days long, how to suppress and mitigate the adverse effects of the weightless environment of astronauts, the China Astronaut Research and Training Center Aerospace Medicine Fundamentals and Applications State Key Laboratory of the greatest challenges. Recently, the reporter had an exclusive interview on this issue of the laboratory director of Li Yinghui. According to reports, when entering the weightless environment, the body will occur a series of physiological changes, if not protective measures, and even cause irreversible pathological changes in the longer time in the weightless environment, the extent of this change is more intense. The Liying Hui said, when the human body from the Earths gravity, reflected changes in vestibular function, accompanied by the head of the body fluids to the distribution. With time, the cardiovascular function change, the muscles gradually atrophy, decreased muscle strength, long time, the skeletal system will also change, including changes in metabolism and bone changes in the structure, these will the bodys normal function is adversely affected. Against the adverse effects of the weightless environment on the human body, the laboratory carried out a lot of foundation experiments, including the ground 60 days head-down bed-rest experiments, women 30 days head-down bed-rest experiment and human verification experiment. It is understood that the Shenzhou No. 9 mission, will use the sets with a total of five kinds of penguin suits, lower body negative pressure tube, bicycle power meter, chest stand-alone product, comprehensive protection, protection against cardiovascular and skeletal muscle to maximum to maintain the bodys cardiovascular function and exercise capacity decline, slow down the process of muscle atrophy, maintain the astronauts in orbit, the ability to work to ensure the health of astronauts. Sets with application to alleviate the humoral transfer led to the symptoms of acute adaptation period in the early stage of space flight. These symptoms usually early in the flight 24 hours The most obvious, gradually weakened, and continue until about 2-3 days after the orbit, so the sets with the use of the program is scheduled to flight the first 1-3 days after the required sets of belt wearing in non-sleep time . Prepare in the penguin suits rendezvous and docking mission flight segment in the combination of wearing Penguin clothes for everyday wear at least eight hours. In the weightless environment, Penguin clothing is the simulation of human activities on the ground when the muscles are gravity load, but the applied force is significantly less than that suffered by the body in the 1G environment load, specific dress requirements as long as possible The timing of dress, wearing no special requirements.
