Publication number: 20110106046Abstract: A connector assembly is provided with a first connector equipped with a first connector body, a hollow needle supported on the inner side of the first connector body and having a side hole (53), and a first sealing member having a head which can be pierced through by the hollow needle; a second connector equipped with a second connector body and also with a second scaling member which can, when in a mounted state, be pierced through by the hollow needle; and a close-contact maintaining means which can, when in the mounted state, maintain that the head and the second sealing member are in close contact with each other. When the second connector becomes pulled out of the first connector, the head and the second sealing member are held in close contact with each other by the close-contact maintaining means until the hollow needle is pulled out of the second scaling member.Type: ApplicationFiled: April 7, 2009Publication date: May 5, 2011Applicant: TERUMO KABUSHIKI KAISHAInventors: Takaaki Hiranuma, Masafumi Takemoto, Hiromitsu Okabe

Patent number: 7427276Abstract: A syringe with which an accurate amount of a liquid can be discharged by a simple operation. The syringe 1 includes an outer tube 2, a gasket 3 slidable in the outer tube 2, a pusher 4 operable for moving the gasket 3, and a stopper 5 disposed to be slidable along the longitudinal direction of the pusher 4. The stopper 5 is fixed relative to the pusher 4 by the engagement of engaging portions, provided therein, with racks 47a, 47b formed on the pusher 4. When an operating portion 71 is depressed, the fixation condition is released, permitting regulation of the position of the stopper 5 on the pusher 4. When the depression on the operating portion 71 is canceled, the fixation condition is retained.Type: GrantFiled: July 20, 2007Date of Patent: September 23, 2008Assignee: Terumo Kabushiki KaishaInventors: Kouichi Tachikawa, Shingo Koyama, Hiromitsu Okabe

Publication number: 20050126653Abstract: A sanitary recovering instrument capable of positively recovering, when excessive chemical liquid and interfusing gas are to be discarded from a liquid filled container pre-filled with a liquid and sealed, them into a closed space. The recovering instrument (1) in a preferable embodiment comprises a container body (2), a hollow needle tube (3), a gasket (4), an enclosing member (5), a cap (6), and a holder (7). When the needle tube (3) is allowed to puncture the elastic membrane (94) of the liquid-filled container (pre-filled syringe (8)), excessive chemical liquid and interfusing air are introduced into the storing space (20) in the container body (2) via the inner cavity (31) of the needle tube (3) to thereby move the gasket (4) slidingly and increase the volume of the space (20) according to the amount introduced.Type: ApplicationFiled: March 13, 2003Publication date: June 16, 2005Applicant: Terumo Kabushiki KaishaInventors: Kouichi Tachikawa, Shingo Koyama, Hiromitsu Okabe
