(57) [Summary] [Purpose] To provide a medical device, particularly a medical device using a material capable of extremely hygienically administering a liquid medicine to a human body. The present invention is a medical device made of a material containing a resin (referred to as a cyclic resin) containing a cyclic olefin compound or a crosslinked polycyclic hydrocarbon compound as a polymer component. The cyclic olefin compound is a monocyclic olefin compound or its alkyl or acrylate derivative, and the crosslinked polycyclic hydrocarbon compound is one or more selected from compounds having an unsaturated bond in the ring or in a substituent. Are particularly preferable, and may be mixed with an olefin resin. It is particularly preferable that the cyclic resin has a bromine number of 5 or less and a softening point of 90 ° C. or more. Medical devices include syringes, transfusion devices, Examples include an infusion set, a blood collection device, a blood transfusion device, an artificial kidney, a catheter, a tube, a blood bag, and a two-chamber syringe with a needle. |
