    • A disposable medicinal application apparatus for use in the administration of a medicinal fluid comprises sealed flexible bag means at least partially filled with a quantity of the fluid to be applied. The apparatus has a neck piece freely enclosed within the sealed bag means, the neck piece being manipulable against the interior surface of a portion of the bag means and the bag wall being stretched over the neck piece. A separate applicator member has a passage in communication with discharge means. Cooperative locking and lockable means are formed on the applicator member and the neck piece, respectively, to allow the applicator member to be snap-fitted and locked to the neck piece, with the bore of the neck piece and the passage of the applicator member in alignment. A portion of the bag wall is compressed between the exterior surface of the neck piece and the interior surface of the applicator member to form a fluid-tight seal therebetween. A portion of the applicator member comprises means for puncturing the bag wall to allow egress of the medicinal fluid through the aligned bore and passage of the cooperatively locked neck piece and applicator member.
    • 用于给药液体的一次性药物施用装置包括至少部分填充有待施用流体量的密封柔性袋装置。 该装置具有自由地封闭在密封袋装置内的颈部件,该颈部可操纵于袋装置的一部分的内表面,并且袋壁被拉伸在颈部件上。 单独的涂抹器构件具有与排出装置连通的通道。 合作的锁定和可锁定装置分别形成在涂抹器构件和颈部件上,以允许涂抹器构件卡扣并锁定在颈部件上,颈部件的孔和涂抹器构件的通道 对准。 袋壁的一部分在颈部件的外表面和涂抹器构件的内表面之间被压缩,以在它们之间形成流体密封的密封。 施用器部件的一部分包括用于刺穿袋壁的装置,以允许医用流体通过对准的孔排出并且协同锁定的颈部件和涂抹器构件的通道。
