Publication number: 20140166108Abstract: The invention relates to a microfluidic platform (1) having at least one means (12) for initiating a movement of a liquid (P), in particular a sample liquid, between at least two locations (100, 101) of the microfluidic platform (1). It is proposed according to the invention that the means (12) is embodied as an element of changeable volume and/or shape and is mounted on a cover-like component (11) that is movably connected to the microfluidic platform (1). By moving of the component (11) the element (12) can be brought into a position such that, by changing its volume and/or shape, it causes the liquid (P) situated at the location (100) to be moved at least partly from this location (100) to the other location (101). In this way a sample liquid (P) can be transferred from a sample application point (100) to a sample utilisation area (101) in a very simple and reliable manner.Type: ApplicationFiled: October 4, 2011Publication date: June 19, 2014Applicant: BOEHRINGER INGELHEIM MICROPARTS GMBHInventors: Tobias Rodenfels, Thanh Tu Hellmich-Duong, Gert Blankenstein

Patent number: 8709353Abstract: A device, particularly a microfluidic system, is proposed, in which two cavities are arranged spatially close to one another and are sealed off from one another by a common cover. A fluidic connection can be produced between the cavities by movement of a pin-shaped body towards the cover. In this way it is possible to release a reagent in controlled manner without having to put it under pressure.Type: GrantFiled: March 16, 2012Date of Patent: April 29, 2014Assignee: Boehringer Ingelheim Microparts GmbHInventors: Berthold Lange, Tobias Rodenfels, Wolfgang Stoeters, Markus Voigt

Publication number: 20140000223Abstract: A method for filling a cavity, of a packaging, particularly a blister packaging, with a liquid and a packaging suitable for this purpose are proposed. The cavity is completely filled with the liquid by an acceleration force or by continuous throughflow.Type: ApplicationFiled: November 3, 2011Publication date: January 2, 2014Applicant: BOEHRINGER INGELHEIM MICROPARTS GMBHInventors: Dirk Osterloh, Dirk Kurowski, Tobia Rodenfels, Gert Blankenstein, Tobias Eichmann, Thanh Tu Hellmich-Duong

Patent number: 8580209Abstract: A microfluidic device meters liquids into a network of channels or chambers partly formed by a film partly attached to and above a substrate, the network permitting flow of fluid above the substrate. To form a channel or chamber, the edge zone between unattached and attached portions of the film forms a wedge of material by viscous flow of film material as the film is laminated to the substrate, this wedge forming a transition between the chamber wall and the substrate, raising the wall above the plane of the substrate. Film is laminated with a mask having an opening, the mask pressed onto the film under pressure and/or with heat. The film is brought to a temperature to produce a viscous flow of film and/or substrate medium into the region of the opening, forming a wedge of material as the film bulges up at the opening to form a chamber.Type: GrantFiled: June 2, 2009Date of Patent: November 12, 2013Assignee: Boehringer Ingelheim Microparts GmbHInventors: Dirk Kurowski, Mario Hempel, Gert Blankenstein, Tobias Rodenfels

Patent number: 8580072Abstract: A device for the intake or manipulation of a fluid, in particular, a liquid, and a method for the production of a device of this type in which a flat, non-preformed covering film is laminated onto a carrier, a three-dimensionally shaped or convex chamber wall being formed solely by means of the laminating process. The chamber wall which forms a boundary of a chamber for the fluid is partially deformable. The device is simple to produce and can be used universally.Type: GrantFiled: December 7, 2007Date of Patent: November 12, 2013Assignee: Boehringer Ingelheim microParts GmbHInventors: Gert Blankenstein, Tobias Rodenfels, Dirk Kurowski, Mario Hempel

Publication number: 20130156643Abstract: A device and a method for manipulating or analysing a liquid sample in a microfluidic channel are proposed. In order to implement an immunoassay, a movable substrate having a binding region is inserted in the channel. The substrate is embodied as a plate-like plastic part and is microstructured in the binding region. It is magnetically movable in the channel and for optical detection can be moved into a gas space.Type: ApplicationFiled: March 14, 2011Publication date: June 20, 2013Applicant: BOEHRINGER INGELHEIM INTERNATIONAL GMBHInventors: Tobias Rodenfels, Gert Blankenstein, Dirk Osterloh

Publication number: 20110135546Abstract: The invention relates to a microfluidic device for metering liquids into a microfluidic network. The microfluidic channels or chambers are at least partly formed by the introduction of suitable structures into a film above the substrate carrier, so that at least some of the flow of fluid through the network takes place above the plane of the substrate. In order to form a stable channel structure or chamber structure in the film, it is envisaged that in the edge zone between the unattached and attached portions a wedge of material is formed by the viscous flow of the film material as the film is bonded to the substrate, this wedge forming a transition between the chamber wall and the substrate and raising the chamber wall above the plane of the substrate. In one method of producing a finished microfluidic structure a flat planar film is laminated onto a flat sheet-like substrate.Type: ApplicationFiled: June 2, 2009Publication date: June 9, 2011Applicant: BOEHRINGER INGELHEIM MICROPARTS GMBHInventors: Dirk Kurowski, Mario Hempel, Gert Blankenstein, Tobias Rodenfels
