Problems solved by technology

At present, the clinical application in our country mainly uses the products of the German Bena company. This filter device firstly processes the patient's plasma chemically, adjusts the pH value, and then removes the plasma by adding heparin-induced chemical precipitation. Cholesterol, triglycerides and other components, this purification method usually takes three hours to complete, and the cost of treatment is also greatly increased due to the high cost of equipment
