<p>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).</p> |
