Patent number: 11224703Abstract: The invention relates to a nozzle for use in a device for administering a liquid medical formulation, to a method for producing the nozzle in the form of a microfluidic component and to a tool for producing microstructures of the microfluidic component. The nozzle is formed by a plastics plate with groove-like microstructures which are covered by a plastics cover on the longitudinal side in a fixed manner. The production method includes a moulding process in which a moulding tool is used, which moulding tool has complementary metal microstructures which have been produced from a semiconductor material in an electrodeposition process by means of a master component.Type: GrantFiled: February 2, 2017Date of Patent: January 18, 2022Assignee: BOEHRINGER INGELHEIM MICROPARTS GMBHInventors: Klaus Kadel, Lothar Keydel

Patent number: 9027854Abstract: A simple, compact construction and easy manufacture of a swirl nozzle having a plurality of inlet channels and an outlet channel extending transversely thereto are made possible by the fact that the inlet channels open directly and/or tangentially into the outlet channel. Alternatively or additionally, upstream of the inlet channels is provided a filter structure having smaller flow cross-sections than the inlet channels. The swirl nozzle is used, in particular, for atomizing a liquid medicament formulation. The swirl nozzle is produced from two plate-shaped components, the outlet channel first being etched as a blind bore in one component and then opened up by grinding the component away. Alternatively or additionally, the outlet channel is formed in a different component from the inlet channels.Type: GrantFiled: March 6, 2007Date of Patent: May 12, 2015Assignee: Boehringer Ingelheim International GmbHInventors: Achim Moser, Klaus Kadel

Publication number: 20110005517Abstract: Disclosed are an atomizer for a fluid, especially for medical aerosol therapy, and a filter for said atomizer in order to prevent germs from spreading. The atomizer comprises a protective device for preventing germs from infesting the preferably preservative-free fluid. Particularly the filter can be used as a protective device. This prevents germs from infesting the fluid during the service life of the atomizer even when the atomizer is used several times.Type: ApplicationFiled: May 13, 2008Publication date: January 13, 2011Applicant: BOEHRINGER INGELHEIM PHARMA GMBH & CO. KGInventors: Georg Boeck, Achim Moser, Klaus Kadel

Patent number: 7815857Abstract: A device and a plurality of microfluidic platforms for taking up and especially studying or manipulating a sample liquid, a measuring instrument for use with the device and platforms, and a process for performing the studying or manipulating of the sample liquid. Very simple, hygienic and user-friendly handling is enabled in that the platforms which are connected to one another in a sealed state and can each be individually separated and individually, preferably simultaneously, opened for taking up of a sample, such as blood, for, e.g., performing a glucose determination.Type: GrantFiled: October 12, 2005Date of Patent: October 19, 2010Assignee: Boehringer Ingelheim microParts GmbHInventors: Christian Dechant, Klaus Kadel, Gert Blankenstein

Patent number: 7645383Abstract: A microstructured filter is presented having an inlet for unfiltered fluid; an outlet for filtered fluid; a plurality of projections, which form at least one row in a mutually juxtaposed relationship across the filter, that project out of a base plate and are an integral component of the base plate; a plurality of passages between the projections; and a cover plate which is securable to the base plate to cover the projections and the passages. The passages form a plurality of through paths from the inlet to the outlet. The inlet includes an elongate inlet slot for the unfiltered fluid that extends over approximately the entire filter width and is approximately as high as the projection on the outlet side of the filter.Type: GrantFiled: October 14, 2005Date of Patent: January 12, 2010Assignee: Boehringer Ingelheim International GmbHInventors: Klaus Kadel, Johannes Geser, Joachim Eicher, Bernhard Freund, Stephen Terence Dunne, Wulf Bachtler
