Beschreibung
Zusammenfassung:	The invention discloses an anticoagulant medical material and a preparation method thereof. A hydroxy-containing natural biological material wheat straw hemicellulose polysaccharide and a sulfur trioxide-pyridine composite are subjected to chemical reaction; and by using the xylose unit in the hemicellulose as the reaction object, the sulfuric acid group is introduced into the hemicellulose polysaccharide to prepare the anticoagulant medical material. Compared with the prior art, the anticoagulant medical material provided by the invention has the advantages of favorable anticoagulation effect, simple preparation technique, low cost, favorable biocompatibility and the like, and has wide application prospects in clinic.
