Patent number: 10888658Abstract: A disposable injector with a piston actuation ram is mounted in a housing, is loaded by a spring energy accumulator and can be unlocked by a displaceable trigger device. The piston actuation ram can be supported by a tensioning rod mounted in the housing. The trigger device comprises a trigger ring displaceable relative to the housing. The tensioning rod can be supported directly or indirectly by a bearing surface of the trigger ring. The bearing surface encloses an angle of between ten degrees and forty five degrees with the longitudinal direction of the disposable injector. The point of the angle lies offset with respect to the trigger ring in the triggering direction of the disposable injector. A disposable injector with increased trigger reliability is developed.Type: GrantFiled: October 25, 2017Date of Patent: January 12, 2021Assignee: LTS LOHMANN THERAPIE-SYSTEME AGInventors: Sara Forghani, Uwe Wortmann, Karsten Heuser, Heiko Spilgies

Patent number: 8262604Abstract: A single-use injector is disclosed comprising a housing (10), arranged in which are at least one mechanical spring energy store (50), at least one piston-cylinder unit (100), which can be effectively filled at least for a certain time, at least one piston-actuating ram (60) and at least one triggering unit (80). The spring energy store comprises at least one pre-tensioned spring element. The spring-loaded piston-actuating ram (60) has at least one retaining rod or hook (62), which can be moved transversely, at least in certain regions, and by means of a supporting portion supports the tensioned spring energy store on at least one resting surface of the housing. When actuation occurs, the triggering unit (80) releases the supporting portion to allow it to move away from the resting surface.Type: GrantFiled: June 10, 2009Date of Patent: September 11, 2012Assignee: LTS Lohmann Therapie-Systeme AGInventors: Bodo Asmussen, Hans-Rainer Hoffmann, Rudolf Matusch, Uwe Wortmann

Patent number: 8197459Abstract: Embodiments of the invention relate to a transfer device for a container whose interior is under negative pressure and which is closed by means of an elastic stopper. The device has a receiving cap and a piercing mandril for piercing the stopper. Relative to its direction of piercing, the piercing mandril is provided with a front piercing portion and with a rear sealing portion which is of greater diameter. In the position in which a bead of the container is inserted into the receiving cap, the sealing portion contacts the stopper. In this way, a tear in the stopper, which tear has been formed by eccentric application of the device onto the container, can be sealed off.Type: GrantFiled: March 4, 2004Date of Patent: June 12, 2012Assignee: Aventis Behring GmbHInventors: Hubert Jansen, Uwe Wortmann

Patent number: 7491197Abstract: Embodiments of the invention include a fluid transfer device, for example, for medical fluids. The device includes a housing, two piercing elements mounted in the housing, and a slide arranged between the piercing elements. The slide may be displaced with respect to the piercing elements such that, in a first position, a flow connection is established between the two piercing elements, and, in a second position, a flow connection is established between one of the piercing elements and a lateral opening of the housing. In the area of the lateral opening, the housing may have a connector for insertion of a syringe cone of a syringe. When the syringe cone is inserted into the connector, the front end of the syringe cone may move the slide from the first position to the second position.Type: GrantFiled: March 5, 2004Date of Patent: February 17, 2009Assignee: CSL Behring GmbHInventors: Hubert Jansen, Uwe Wortmann

Publication number: 20080287885Abstract: The invention relates to a cylinder/piston unit having a cylinder and a piston which is guided therein, wherein the cylinder and the piston enclose a chamber which can be filled at least for a time with an additive, and the cylinder has at least one exit element at its front end. Here, the cross section of the chamber or the cross section of the cylinder inner wall is increased at least in regions of the cylinder from the front to the back, wherein the cylinder end having the exit element is at the front. The piston has an elastic skirt at least in the front region, the front outer edge of said elastic skirt defining a cross-sectional area in the case of an unloaded piston, which is greater than an area which is defined by a contour line. The present invention develops a cylinder/piston unit which ensures simple and reliable handling and can be stored for a long time in the filled state, in a manner which is impervious to gas and moisture.Type: ApplicationFiled: November 2, 2006Publication date: November 20, 2008Inventors: Hans-Rainer Hoffmann, Bodo Asmussen, Uwe Wortmann
