In recent years, as interest in and development of artificial organs such as artificial blood vessels and artificial hearts has increased, artificial organs using polymeric materials have become actively researched. Ordinary polymeric materials have the property of coagulating blood when they come into contact with blood, so they cannot be used for long periods of time in living organisms that come into contact with blood.

However, polymer materials are very suitable as materials for artificial organs due to their excellent properties, and there is a strong desire for polymer materials that do not cause coagulation even when in contact with blood for a long period of time. As a method of imparting anticoagulant properties, attempts have been made to bind heparin, known as an anticoagulant, to polymeric materials, but the conventional methods require long-term contact with blood. However, no polymeric material has yet been found that can be put to practical use because it causes blood clots or is too fragile.

Furthermore, attempts have been made to react heparin with a cationic compound and mix it with a resin, but there is a fear that the heparin will elute into the blood and the cationic compound will also elute, raising concerns about the toxicity of the cationic compound. . The inventors
As a result of repeated research to provide a medical molded article with novel anticoagulant properties that improves these drawbacks, we have developed a mixed composition obtained by mixing a partially quaternary ammonium polyepihalohydrin polymer and a methacrylate resin. The present invention was completed by discovering that a material obtained by molding into a predetermined shape and reacting with an alkali metal salt of heparin has excellent anticoagulant properties and appropriate physical properties.

The molded articles of the present invention exhibit excellent anticoagulant properties and are biologically and chemically stable even after long-term contact with blood. Furthermore, since the molded article of the present invention is obtained by reacting an alkali metal salt of heparin after molding into a predetermined shape, heparin binds only to the surface of the molded article, making it possible to utilize heparin effectively. Furthermore, by changing the mixing ratio of the partially quaternary ammonium-containing polyepihalohydrin polymer and the methacrylate resin, the hardness and softness of the molded product can be controlled, so it can be used in contact with blood, such as in artificial blood vessels, artificial hearts, and blood transfusion sets. The molded article can be made to have an extremely suitable material as a medical molded article. Furthermore, depending on the type of methacrylate resin used, it is possible to obtain a transparent molded body, which is very advantageous when used for medical purposes. Next, the present invention will be specifically explained with reference to Examples, but the present invention is not limited to these Examples.
