• This paper discusses how to solve the physiological and psychological problems that may be encountered in space travel through Cyborg technology and biomedical means to improve the survival ability and adaptability of astronauts.By combining biochemistry, pharmacology, sensor technology and automatic control, this paper discusses the physiological adaptability of human beings in outer space environment.
• Biochemical and pharmacological research : The article mentions the use of drugs (such as epinephrine, fluoxetine, etc.) and chemicals to regulate and adapt human physiological functions in the outer space environment. This includes the study of enzyme systems, exploring the changes in the activity of certain enzyme systems under hypothermia conditions, and the effects of drugs on the activity of these enzymes.
• Physiological monitoring and Control systems : The researchers propose the use of sensors to monitor physiological parameters (such as blood pressure) and regulate these parameters through drugs. This approach involves the application of the theory of biological control systems aimed at maintaining physiological balance through automated drug delivery systems.
• Environmental Adaptation experiments : The experimental methods mentioned in the article include transforming certain organisms from an aerobic state to an anaerobic state through in vitro radiation to study changes in enzyme systems and explore their potential applications in humans.
• Drug and Chemical Regulation: Researchers explore the use of drugs and chemicals to address the physiological challenges of the outer space environment, such as weightlessness, pressure changes, and temperature changes. For example, the use of drugs to deal with vestibular dysfunction, or chemical regulation to maintain body temperature.
• Application of technical means : Technical means such as the “Rose syringe” mentioned in the article can achieve the continuous release of drugs in the biological body, supporting the adjustment and adaptation of physiological functions
• ** Biologic Drug Delivery System ** : The article describes a capsule that can be continuously and slowly injected with a bioactive substance, which can be implanted in the body, allowing continuous release of the drug at a variable rate in a specific organ.
• ** Radiation Protection ** : A sensor is mentioned that can detect radiation levels and automatically inject protective drugs to improve resistance to radiation.
• Metabolic control vs. cryogenic control: During long-term spaceflight, lowering body temperature to reduce metabolism and human “fuel” consumption is considered a viable strategy.
• ** Oxygen supply and carbon dioxide removal ** : The concept of a reverse fuel cell is proposed, which can convert carbon dioxide into its components and recover oxygen, thus replacing traditional breathing methods.
• ** Fluid intake and discharge ** : Fluid balance is maintained through shunt of urethra and venous circulation, and fecal discharge is reduced.
• Regulation of enzyme systems ** : Under low temperature conditions, the activity of certain enzyme systems may increase, and drugs or chemicals may affect the activity of these enzymes.
• ** Muscle Maintenance ** : During long-term space travel, medical protection to maintain muscle tone is necessary.
• ** Perception problems ** : Lack of atmosphere can cause significant changes in visual perception, and the article suggests providing a medium to help astronauts adapt to these changes.
• ** Pressure and Temperature control ** : At a pressure below 60 mm Hg, the body’s blood will begin to boil, so the body temperature needs to be lowered to avoid the use of pressure clothing.

Interesting Point

• Cyborg and biological adaptation ** : The article presents a unique idea of modifying human physiological functions to adapt to alien environments through Cyborg technology. This line of thinking emphasizes that rather than creating an Earth environment in space, it is better to enhance human self-regulation directly through a combination of biology and electronics. This view challenges the traditional theory of biological adaptation and holds that humans can actively participate in their biological evolution through technological means
