  • Patent number: 11065621
    Abstract: A microfluidic device includes a chamber substrate, a cover substrate, a flexible membrane, and a punch unit. The chamber substrate includes a fluid chamber configured to receive a fluid and having a fluid chamber opening. The cover substrate includes a punch opening lying opposite the fluid chamber opening. The flexible membrane is positioned between the chamber substrate and the cover substrate, and spans the punch opening and the fluid chamber opening. The punch unit is configured to move into the fluid chamber through the punch opening in order to deflect the flexible membrane into the fluid chamber so as to enable the fluid to flow out of the fluid chamber when fluid is received in the fluid chamber.

  • Patent number: 11027276
    Abstract: A film bag for a microfluidic analysis system includes a film bag bottom, a film bag opening arranged opposite the film bag bottom, and a peel seam arranged between the film bag bottom and the film bag opening. The peel seam is formed to produce a closed reagent receiving region between the peel seam and the film bag bottom and a tube between the peel seam and the film bag opening. The reagent receiving region has a reagent receiving length extending between the peel seam and the film bag bottom. The tube has a tube length extending between the peel seam and the film bag opening. The tube length is at least five percent of the reagent receiving length.

  • Publication number: 20210053052
    Abstract: A microfluidic device for processing a liquid in ludes at least one pneumatic substrate with a pneumatic cavity and a fluidic substrate with a fluidic cavity for accommodating the liquid. The fluidic cavity is arranged opposite the pneumatic cavity. In addition, the microfluidic device has a flexible membrane which is arranged between the pneumatic substrate and the fluidic substrate. The flexible membrane is designed to fluidically separate, from one another, a fluidic chamber extending at least in part in the fluidic cavity and a pneumatic chamber extending at least in part in the pneumatic cavity. The microfluidic device further includes a first pneumatic channel for applying a first pneumatic pressure to the pneumatic chamber and a second pneumatic channel for applying a second pneumatic pressure to the pneumatic chamber.

  • Patent number: 10562026
    Abstract: A device, especially a microfluidic device for performance of an immunoassay, has a first, a second and a third fluidically connected chamber and a membrane. In the event of a given deflection of the membrane into the first chamber, a first fluid is passed at least partly out of the first chamber into the second chamber in such a way that a second fluid is at least partly displaced from the second chamber into the third chamber in such a way that the third chamber is entirely filled with the second fluid.

  • Publication number: 20190265259
    Abstract: A processing system includes a processing unit configured to process a cartridge, in particular a microfluidic cartridge, and is further configured to process a biological sample received in the cartridge. The processing unit includes a computing unit configured to compare input or read in sample data with input or read in first cartridge data in order to determine a compatibility of the sample with the cartridge. The computing unit is further configured to output a first error message in response to a determination of incompatibility between the sample and the cartridge. A method includes using the processing system to determine a compatibility between a sample and a cartridge.

  • Patent number: 10160943
    Abstract: A method for processing organic cells includes providing a microfluidic system having a chamber comprising a stationary phase in the form of a plurality of microparticles. The method further includes letting a plurality of organic cells in a mobile phase into the chamber across a first opening of the microfluidic system. The method further includes accumulating the organic cells in a tapered section of the chamber that is upstream of a filter of the microfluidic system that is impermeable to the microparticles. The method further includes flushing a lysis agent into the chamber to resuspend the microparticles and the organic cells in the chamber for a disruption of the organic cells.
