The treadmill is placed in the lower body negative pressure cabin, and the lower body The ballast chamber is used to provide a negative pressure environment, and the instrument panel is used to set the treadmill, control the pressure in the cabin and display data. The invention realizes lower body negative pressure exercise while running exercise, can effectively alleviate cardiovascular dysfunction caused by weightlessness, and improve exercise efficiency.

Description

lower body negative pressure treadmill

technical field

The invention relates to a lower body negative pressure treadmill which can carry out physical exercise and lower body negative pressure exercise at the same time.

Background technique

The weightless environment during spaceflight can cause adaptive changes in various human systems, including cardiovascular dysfunction, muscle atrophy, and bone loss, threatening the health and safety of astronauts. Among them, the change of human blood distribution caused by weightlessness causes a large amount of blood from the lower body to be transferred to the upper body, which is the main cause of head and face edema and cardiovascular dysfunction. Among the current countermeasures against the above-mentioned changes, physical exercise is the most basic and most commonly used countermeasure. It mainly increases the work of muscles through exercise, which produces a kind of force stimulation to muscles and bones. Consumption, strengthen the regulation of the cardiovascular system, and promote the coordination of cardiovascular system functions. Because running provides the most stimulation compared to other training, the treadmill is the preferred exercise equipment for astronauts when flying. The space stations of Russia and the United States are equipped with treadmill devices. When using them, an elastic belt must be used to fix the astronauts on the treadmill and apply a certain amount of pressure. If the astronauts use the treadmill for physical exercise during the spaceflight, and then use the special lower body negative pressure device to transfer the blood to the lower half of the body, resulting in a state similar to the blood distribution under normal gravity on the ground, which can further improve the exercise efficiency and effectively reduce the pressure on the body. Cardiovascular effects of weightlessness. However, the treadmills used in aerospace flight cannot change the blood distribution of the human body at the same time, and cannot perform lower body negative pressure exercise while running.

Contents of the invention

The object of the present invention is to provide a lower body negative pressure treadmill which is suitable for use on a space station and can perform physical exercise and lower body negative pressure exercise at the same time.

The technical solution adopted in the present invention is: the lower body negative pressure treadmill is composed of a base, a running platform, a bracket, a handrail, an instrument panel, a lower body negative pressure cabin and a vacuum pump, the running platform is placed in the lower body negative pressure cabin, and the instrument panel is used to set the running Machine, control cabin pressure and data display, vacuum pump is used to generate negative pressure, lower body negative pressure cabin is used to provide negative pressure environment.

The beneficial effects of the present invention are: the astronauts run and exercise in the negative pressure cabin of the lower body, realize the negative pressure exercise of the lower body while running and exercising, the suction of the negative pressure of the lower body fixes the astronaut on the treadmill and applies a certain pressure, The blood distribution is similar to that under the gravity of the ground, effectively reducing the cardiovascular effect caused by weightlessness, and the exercise efficiency is higher and the effect is more obvious.

Detailed ways

As shown in Figure 1, the lower body negative pressure treadmill is composed of instrument panel 1, armrest 2, support 3, vacuum pump 6, base 7, running platform 8 and lower body negative pressure cabin 10, instrument panel 1 is fixed on the support 3, armrest 2 Link to each other with support 3 by fastening connection, support 3 is installed on the base 7, and running platform 8 is housed on the base 7 for running exercise. The treadmill 8 is installed in the lower body negative pressure cabin 10, which is a cuboid structure surrounded by pressure-resistant plexiglass. superior. An oval opening is reserved in the upper center of the lower body negative pressure chamber 10, and the oval opening is connected with the sealing shroud 9. A pressure measuring hole 4 and an air extraction hole 5 are reserved near the edge of the lower body negative pressure chamber 10 . The pressure measuring hole 4 is connected to the instrument panel 1 through a pressure-resistant hose, and the air extraction hole 5 is connected to the vacuum pump 6 through a pressure-resistant hose. The vacuum pump 6 is fixed on the bracket 3, and is connected with the instrument panel 1 through wires. The control of the vacuum pump 6, the display of the pressure in the cabin and the setting of the treadmill are all completed by the instrument panel 1.

During use, the trainee stands on the running platform 8 in the negative pressure cabin 10 of the lower body, and is surrounded by a sealing band 9 under the xiphoid process. Utilize instrument panel 1 to set treadmill parameter and lower body negative pressure pressure value respectively, then start treadmill and vacuum pump 6, trainee begins to exercise on treadmill 8, and the pressure in lower body negative pressure chamber 10 starts to drop simultaneously, waits to reach setting When the value is set, the vacuum pump 6 stops working automatically. The instrument panel 1 automatically controls the pressure in the cabin and maintains it within the set range.
