Document Type and Number:
WIPO Patent Application WO/2012/117622
Kind Code:
A1
Abstract:
In order to make it possible to seal a medicine in a storage container and cause the storage container and a needle tube to communicate with each other without the occurrence of coring and the deformation of the needle point of the needle tube, a prefilled syringe (1) is provided with a barrel (2), a needle tube (3), a needle hub (4), and a lid member (6). The lid member (6) is configured to make a transition between a first state in which a discharge hole (12a) of a discharge part (12) is closed, and a second state in which a through-hole (6a) provided in the lid member (6), the needle tube (3), and the discharge hole (12a) of the discharge part (12) communicate to thereby form a flow path through which a medicine (M) passes, by the rotation of the needle hub (4).
