Problems solved by technology

Blood circulation disorder during weightlessness is similar to "blood stasis" in traditional Chinese medicine. After blood circulation disorder occurs, the astronaut's weight, breathing and other physiological parameters may not change, only the position of the center of gravity has changed. Currently, the astronaut's center of gravity There is still a gap in detection, there is no such device to detect the center of gravity of astronauts

Embodiment 1

[0031] Such as figure 1 , 2 Shown in and 3, the center of gravity position measuring device of the human body under the space station weightlessness environment of the present invention comprises a fixed mechanical arm at one end, and a square hard flat plate 1 is fixed at the other movable end of the mechanical arm, and four hard flat plates are arranged on the hard flat plate 1. The pressure sensor 2 and the two intersecting fixing bands 3 are arranged in a rectangular shape on the hard plate 1, that is, the geometric figure surrounded by connecting lines with each pressure sensor 2 as a vertex is a rectangle. There are at least three pressure sensors 2, because during detection, the hard plate 1 is probably located at the waist of the subject, and the waist is where the center of gravity of a person is in a normal state, but in a weightless state, the center of gravity of the human body will change , but still near the waist, in order to find the position of the center of ...

Embodiment 2

[0053] Embodiment 2: as Figure 5 As shown, the mechanical arm of the present invention can also adopt the following structure. The mechanical arm includes a turntable 14 fixed on a horizontal plane, and a vertical first guide rail 15 is provided on the turntable 14. The first guide rail 15 and the turntable 14 Constitute a rotating pair, the axis of the rotating pair is perpendicular to the horizontal plane; the first slide block 16 is provided on the first guide rail 15, the first slide block 16 and the first guide rail 15 constitute the first moving pair, the first slide block 16 is on the first Guide rail 15 moves vertically; On first slide block 16, be provided with horizontal second guide rail 17, be provided with second slide block 18 on second guide rail 17, second slide block 18 and second guide rail 17 constitute the first Two moving pairs, the second slider 18 moves horizontally on the second guide rail 17; the hard plate 1 is vertically arranged at the end of the s...

Abstract

The invention discloses a measuring method for human body gravity center positions in a space station zero gravity environment, which comprises a mechanical arm, wherein a hard flat plate is arranged at one end of the mechanical arm, a plurality of pressure sensors capable of enclosing an area with a certain area are arranged on the hard flat plate, a fixing tape used for fixing bodies of test subjects is further arranged on the hard flat plate, a supporting plate is arranged on the pressure sensors, and a space for containing the bodies of the test subjects is formed between the fixing tape and the supporting plate. The pressure sensors are connected with a single chip microcomputer module through a signal conditioning module, and the single chip microcomputer module is connected with anupper computer. The invention further discloses a method for measuring human body gravity centers in the space station zero gravity environment by using the measuring device. The measuring device andthe measuring method are simple in structure, low in cost and convenient to use, fill in gaps in astronaut gravity center detection in the zero gravity environment, and have important meaning for development of the space industry.

Description

technical field [0001] The invention relates to a human body physiological parameter detection system, in particular to a measuring device and a measuring method for the position of the center of gravity of a human body in a weightless environment of a space station. Background technique [0002] The launch of Tiangong-1 marks that my country has the ability to establish a preliminary space station, and the country plans to build a manned space station around 2020. When more and more astronauts are in close contact with space and carrying the sacred mission of mankind, their weightlessness in space will cause a series of physiological changes, and even pathological reactions or diseases, which will affect the physical and mental health of astronauts, so Astronaut health check is very necessary. Staying in the weightless environment of spaceflight for a long time can cause adaptive changes in multiple systems of the body and changes in some pathophysiological properties. Amo...
