Technical Field

[0001] The utility model relates to the technical field of sodium heparin processing equipment, in particular to a desorption device for sodium heparin extraction. Background Art

[0002] Heparin sodium is mainly extracted from the small intestinal mucosa of pigs and sheep and bovine lungs. After the raw materials are heated and enzymatically hydrolyzed, the heparin sodium is adsorbed by resin, then slowly washed with sodium chloride solution, the eluate is collected, and then filtered, dehydrated and dried to obtain heparin sodium.

[0003] During the extraction and desorption process of sodium heparin, some fixed residues will be attached to the inside of the tank.
