Self-regulation type pressure gradient anti-G suit and regulation method

Abstract

The invention discloses a self-regulation type pressure gradient anti-G suit and a regulation method. An electrocardio patch, a blood pressure cuff and a blood oxygen detector are used for monitoring real-time values of electrocardio, blood pressure and blood oxygen respectively and inputting the real-time values into a controller, the real-time values are compared with normal reference values under a 1g gravity field one by one, any real-time value in an overweight state is increased to 30% or above of the normal reference value, any real-time value is reduced to be more than 30% of a normal reference value in a weightless state, the pressurization rate of a waist pressurization belt is kept within a fixed range value in an overweight state, and the pressurization rates of a hip pressurization belt, a thigh pressurization belt and a shank pressurization belt from top to bottom are gradually reduced according to a gradient relative to the pressurization rate of the waist pressurization belt; in a weightless state, the pressurizing speed of the shank pressurizing belt is kept within a fixed range value, the pressurizing speed of the pressurizing belt from bottom to top is gradually reduced according to gradients relative to the pressurizing speed of the shank pressurizing belt, gradient pressurizing on the human body is achieved, and the problem of blood flow pressure difference change of all parts of the human body is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of safety protection equipment for aerospace flight personnel, and in particular relates to a self-regulating pressure gradient anti-G suit. Background technique [0002] Aerospace activities are a human-centered process. In this process, only the normal ability of the astronauts can complete the scheduled tasks. However, in the process of actually performing aerospace tasks, the acceleration overload acting on the pilot's body will make the The body shows obvious changes in hemodynamic and biomechanical properties, often far exceeding the tolerance limit of the human body, seriously affecting the working status and even life safety of the flight crew, and also limiting the performance of the aerospace vehicle. For example: when the acceleration value reaches about +4~5.5Gz, the flight crew may have reactions such as black vision or loss of consciousness; when the acceleration value reaches about +7~10Gz, th...
