Patent number: 6932789Abstract: Needle-less injectors for liquids are known in many different forms which are adapted to different conditions of use. The needle-less injector according to the invention is in the form of a hand-held unit. It includes a locking stressing mechanism, an energy-storing spring (36), a hollow plunger (37) displaceable in a cylinder (38) and a nozzle (39). At its one end, the hollow plunger is provided with a valve body (42). The supply container (44) for the liquid is arranged within the housing. When the locking stressing mechanism is stressed by rotation of the two housing portions (31, 32) relative to each other the hollow plunger (37) is drawn out of the cylinder (38); at the same time the amount of liquid required for an injection is conveyed out of the supply container (44) through the plunger into the pump chamber (43). After the locking stressing mechanism is triggered the amount of liquid is expelled from the pump chamber through the nozzle.Type: GrantFiled: July 14, 2003Date of Patent: August 23, 2005Assignee: Boehringer Ingelheim International GmbHInventors: Bernd Zierenberg, Ralph Christian Reimholz, Knut Elbers, Stefan Henke, Joachim Eicher, Johannes Geser

Patent number: 6918547Abstract: A miniaturized device for producing high pressure in a fluid imposes stringent requirements on the manufacturing process. The device according to the invention consists of a hollow piston displaceably mounted in a cylinder and a valve member which is guided by the hollow piston and mounted so as to be axially movable relative to the hollow piston. The valve member is arranged at one end of the hollow piston inside or immediately in front of the end of the hollow piston. The device is used in a mechanically operated high pressure atomizer. This consists of a two part housing which comprises a pump housing with nozzle, a blocking mechanism, a spring housing with spring, a non-pressurized storage container for the fluid and a medical counter integrated in the spring housing. The valve operates without any auxiliary force, closes very rapidly and is sealed tight against high pressure. The atomizer is safe and simple to operate and environmentally friendly. The fluid is metered extremely accurately.Type: GrantFiled: March 24, 2004Date of Patent: July 19, 2005Inventors: Joachim Jaeger, Pasquale Cirillo, Joachim Eicher, Johannes Geser, Bernhard Freund, Bernd Zierenberg

Publication number: 20050001076Abstract: A microstructured nozzle consists of a number of channels produced by microstructuring a plate-shaped member. In the nozzle the channels are located between projections which are arranged side by side in rows and project from a base plate. This microstructured base plate is covered with a cover plate. The channels are narrowly defined in terms of shape, cross sectional area and length. The nozzle contains a filter as the primary structure and a secondary structure downstream of the filter. The nozzle is used, for example, with an atomiser which produces an aerosol from a fluid containing a medicament.Type: ApplicationFiled: June 25, 2004Publication date: January 6, 2005Applicant: Boehringer Ingelheim International GmbHInventors: Joachim Eicher, Johannes Geser, Matthias Hausmann, Holger Reinecke

Publication number: 20040143235Abstract: Foil bags are used as a primary packaging for liquids, the bags permitting the liquid to be taken therefrom without the application of a considerable amount of force. A container is provided for a medicinal liquid, the container being gas-tight and liquid-tight so that it is storable over many months. The container includes a collapsible foil bag on which a flange, which is stable in respect of shape, is disposed. The flange is designed for fitting onto a discharge connection member. The container can be disposed in a casing which is stable in respect of shape. The medicinal liquid does not come into contact with air and is protected from the effect of light. The medicinal liquid may be dispensed from the foil bag in many partial quantities over a prolonged period of time, with a respective partial amount thereof being converted into an aerosol by means of an atomizer.Type: ApplicationFiled: January 12, 2004Publication date: July 22, 2004Applicant: Boehringer Ingelheim GmbHInventors: Bernhard Freund, Dieter Hochrainer, Heinrich Kladders, Bernd Zierenberg, Joachim Eicher, Johannes Geser, Martin Essing, Holger Reinecke

Publication number: 20030209238Abstract: A fluid can be discontinuously atomized with an atomizer of the present invention. The atomizer can include a helical spring, disk spring or gas spring, acting as a pressure spring, as an energy storage device, a cylinder, piston, two ducts and two valves. Atomization can be initiated manually by triggering a locking mechanism. The energy storage device can be disposed outside a storage container for the fluid. The energy storage device can be provided mechanical energy manually. Via the piston, the stored energy can exert pressure onto the fluid in the cylinder, which ranges from 1 MPa to 5 MPa (10 bar to 50 bar). Distribution of the droplet size in the atomized jet can be independent from the level of experience and behavior of the person actuating the atomizer, and can be adjusted in a reproducible manner. The mean droplet diameter can be smaller than about 50 micrometers. The mass flow of the fluid through the nozzle can be less than about 0.4 g/s.Type: ApplicationFiled: November 7, 2002Publication date: November 13, 2003Applicant: STEAG microParts GmbHInventors: Ralf-Peter Peters, Joachim Eicher, Holger Hollmann, Holger Reinecke, Stephen Terence Dunne

Patent number: 6503362Abstract: A nozzle assembly for use in atomizing and generating sprays from a fluid. The nozzle assembly includes two members, each with generally planar surfaces, that are joined together. A first set of channels is formed in the generally planar surface of a first one of the members to form, in cooperation with the generally planar surface of the second of the members, a plurality of filter passageways. A plenum chamber is formed in the first member. The plenum chamber is in fluid communication with and downstream of the plurality of filter passageways. A second set of channels is formed in the generally planar surface of the first member to form, in cooperation with the generally planar surface of the second member, a plurality of nozzle outlet passageways. These nozzle outlet passageways are in fluid communication with the plenum chamber.Type: GrantFiled: December 27, 1999Date of Patent: January 7, 2003Assignee: Boehringer Ingelheim International GmbHInventors: Frank Bartels, Wulf Bachtler, Stephen Terence Dunne, Joachim Eicher, Bernhard Freund, William Barrie Hart, Christoph Lessmoellmann

Patent number: 6453795Abstract: A spring-actuated output drive device is used for example in medical aerosol therapy for a miniaturised high-pressure producing device for atomising a small dose of a liquid medicament. A locking-stressing-mechanism for such an output d rive device is to be stressed with the application of a relatively small amount of force and is to be released with one hand and is to operate reliably over a prolonged period of time. The locking-stressing-mechanism comprises a force step-up transmission, for example a screw thrust transmission for stressing the spring, an annularly arranged locking member with engaging locking surfaces, two abutments for limiting the travel of the spring and a release button. It is compact, economical to produce, easy to assemble and comprises components with a low rate of wear. It can be reliably and easily handled by unskilled persons, even when high spring forces are involved. A medicament to be atomised can thus be metered with a very high degree of accuracy.Type: GrantFiled: November 10, 1998Date of Patent: September 24, 2002Assignee: Boehringer Ingelheim International GmbHInventors: Joachim Eicher, Michael Schyra, Richard Forster
