It is indispensable to have line contrast. Although plastics (polymer materials) are often used in medical devices, the polymer materials are basically light-transparent and X-ray transparent at the same time, and it is necessary to achieve the above-mentioned object by some means. Heretofore, as a method for imparting X-ray contrast property to plastics, it has been carried out to mix plastics with a heavy metal salt such as barium sulfate or bismuth bicarbonate, or an inorganic compound such as metal tungsten powder.

大きくする必要があり、従って内容を容易に確認する事
は難しいのが現状であった。When these materials are used, the medical device becomes optically opaque due to the inherent problems of the materials,
In addition, there are many cases in which it is not desirable because it may be colored yellow or black. The specific problem becomes remarkable especially when a catheter is used. That is, the condition of the fluid existing in the pipe cannot be confirmed. As a suboptimal measure for solving this problem, a catheter in which a resin containing a contrast material is put in a stripe shape is used. However, in order to secure a sufficient contrast property, it is necessary to increase the stripe width occupied by these contrast agents, and thus it has been difficult to easily confirm the contents.

の溶出が避けられず安全性において問題である。On the other hand, studies have been conducted on a contrast-imparting material having transparency. Specifically, US Pat. No. 4,282,876 discloses an example in which a halogenated low molecular weight compound is plastically mixed by utilizing the fact that bromine and iodine have X-ray absorbing properties. However, this method cannot avoid the elution of the contrast agent, which is a problem in safety.

る。Further, Japanese Patent Laid-Open Publication No. 6-23034 discloses a material using halogenated polyurethane, which has a contrast property and a light transmission property, and a catheter using the same. However, in the present invention, it is necessary to newly synthesize a halogenated polyurethane, and it is not practical to synthesize one by one for each medical device having greatly different required physical properties. Further, since polyurethane uses a chain extender or a polyether as a soft segment, the content of halogen in the polymer does not become high, and the polyurethane tends to be insufficient in terms of X-ray contrast.
