Application of nitrogen in the field of medicine: Nitrogen is the main component of air. It is a colorless, odorless, non-toxic and non-flammable gas at room temperature and atmospheric pressure. The boiling point is -195.8 °C, and its chemical properties are inactive. In addition to synthetic ammonia, nitrogen is usually used as a protective gas for metallurgy, chemicals, coal, food, medicine, electronics, magnetic materials, transportation, heat treatment, tires, thermoelectricity, aviation and other industries. Nitrogen protection is required in the production of easily oxidized water needles, large infusion, and some raw drugs.
