预灌封注射器
摘要：
本发明的预灌封注射器(1)包括：外筒(2)、能够沿外筒(2)的中心轴移动的药液容器(14)、移动操作药液容器(14)的按压部(4)、两头针(10)、支承两头针(10)的针支承部(8)、以及将外筒(2)和药液容器(14)之间密封的密封构件(9)。此外，在药液容器(14)内部形成有密封容器内部并能够在内部滑动的封闭体(6)。而且，在将按压部(4)向前端侧按压时，两头针(10)的另一端与药液容器(14)的内部连通之后，针支承部(8)抵接于封闭体(6)，使其向药液容器(14)的基端侧滑动，并且与药液容器(14)嵌合，能够在外筒(2)内移动。由此，能够将使用后的穿刺针(10)拉入并收纳于外筒(2)内。
摘要（英）：

A prefilled syringe (1) is provided with an outer tube (2), a medical liquid container (14) which can move along the center axis of the outer tube (2), a pressing section (4) which operates and moves the medical liquid container (14), a double-headed needle (10), a needle support section (8) which supports the double-headed needle (10), and a seal member (9) which seals between the outer tube (2) and the medical liquid container (14). A sealing body (6) which seals the inside of the medical liquid container (14) and can slide within the container (14) is built therein. When the pressing section (4) is pressed to the front end side, after the other end of the double-headed needle (10) is communicated with the inside of the medical liquid container (14), the needle support section (8) makes contact with the sealing body (6) to slide the sealing body (6) to the base end side of the medical liquid container (14) and is fitted in the medical liquid container (14). As a result, the needle support section (8) can move within the outer tube (2). The configuration enables a used insertion needle (10) to be pulled into and contained within the outer tube (2).
