Definitions

  • the present invention relates to the field of medical devices, and in particular to an acetone detecting device for breathing gas in a diabetic patient.
  • Diabetes is a growing problem worldwide, with diabetes being a series of metabolic syndromes such as sugar, protein, fat, water and electrolytes. From a medical point of view, diabetes is caused by the absolute or relative lack of insulin leading to complex metabolic disorders, mainly due to increased glucose levels or dense fat tissue hyperplasia. In the absence of insulin, the direct source of energy in the human body is no longer glucose. Instead, ketones, such as acetone, are produced in the blood and can be excreted in the urine and respiratory channels. The concentration of acetone in the respiratory gas reflects the metabolism of diabetic patients to some extent. In the blood of healthy humans, the content of acetone is always maintained at a certain level, but the level of acetone in diabetic patients is significantly increased. This increase in acetone caused by diabetes is one of the most common pathological phenomena.
