<P>PROBLEM TO BE SOLVED: To provide a two-chamber type prefilled syringe in which each plug body is easily attached, is provided inexpensively, and further while liquid stored in a second storage chamber is heated and sterilized with steam, chemical liquid is frozen and dried in a first storage chamber, and a cylinder body is easily formed by a synthetic resin material. <P>SOLUTION: A front side cylinder body part (2a) and a back side cylinder body part (2b) which are independent of each other are joined airtight to be formed into a cylinder body (2). A front side plug body (5) is attached inside the front side cylinder body part (2a) to form the first storage chamber (8) at the back of the front side plug body (5). Inside the back side cylinder body part (2b), an intermediate plug body (6) and a back side plug body (7) are attached from the front side in order to form the second storage chamber (9) between the intermediate plug body (6) and the back side plug body (7). On an inner peripheral surface of the first storage chamber (8) between a part near the back end of the front side cylinder body part (2a) and a part near a front end of the back side cylinder body part (2b), a bypass (16) for canceling seal by the intermediate plug body (6) is formed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
