Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a ketoacidosis odor detector. Background Art

[0002] Ketone bodies are intermediate metabolites produced by the breakdown and utilization of fatty acids in the liver. They include acetoacetate, β-hydroxybutyrate, and acetone. Under normal circumstances, the body produces a small amount of ketone bodies, which are transported in the blood to tissues such as the heart, kidneys, and skeletal muscle for use as an energy source. Blood ketone concentrations are very low, generally not exceeding 1.0 mg / dL, and ketone bodies are undetectable in urine. When insulin deficiency or a lack of sugar in the body occurs, such as during starvation, fasting, worsening diabetes, and severe pregnancy, excessive fat breakdown can lead to elevated ketone body concentrations. Some ketone bodies are excreted in the urine, forming ketonuria. When the amount of ketone bodies produced in the liver exceeds the capacity of extrahepatic tissues to utilize them, blood ketone concentrations become excessive, resulting in ketonemia and ketonuria. Acetoacetic acid and β-hydroxybutyric acid in ketone bodies are both acidic substances. When they accumulate too much in the blood, they can make the blood acidic and cause acidosis, which is called ketoacidosis. Patients with diabetic ketoacidosis exhale gas that smells like rotten apples. The main component of the gas is acetone. When determining the cause of ketoacidosis, an odor detector will be used for detection.

[0003] When using an existing ketoacidosis odor detector, the air nozzle is generally plugged into the detector. After a long period of plugging and unplugging, the joint will be deformed by friction, which will lead to a decrease in the sealing between the air nozzle and the joint. At the same time, the data detected by the existing ketoacidosis odor detector each time is relatively single, which affects the detection accuracy. Utility Model Content
