Description

[0001] The present application relates to the technical field of bilirubin adsorption treatment, in particular to a bilirubin adsorption column saturation detector and a real-time bilirubin detection method. BACKGROUND

[0002] Bilirubin is the main product of hemoglobin metabolism, and patients with severe hepatitis cannot metabolize bilirubin, which often develops into hyperbilirubinemia. Bilirubin adsorption is an important method for treating severe hepatitis hyperbilirubinemia. At present, various adsorption columns are applied in clinical practice, but there is no device in clinical practice that can detect the real-time saturation of the adsorption column during the process of bilirubin adsorption treatment. In actual operation, only the previous experience is relied on, and after about 3000-5000ml of plasma is adsorbed, saturation is reached. If the bilirubin adsorption column has not reached the saturation degree, the treatment will be ended, which will cause the waste of the adsorption material on the bilirubin adsorption column.
