Patent ID: 11739745

Abstract:
A micropump system (100) for a compressible fluid (102) includes a plurality of micropumps (110), rigid flow duct elements (120), a control unit (130), and one or two printed circuit boards (140). The micropumps have an intake opening (112) and an outlet opening (114). The rigid flow duct elements are connected to a respective micropump via a respective, elastically sealed port (122) and with the micropumps form a flow path (104) for the fluid. The one or two printed circuit boards are arranged and configured to electrically connect the control unit to the plurality of micropumps. Each micropump is rigidly fastened to the one or two printed circuit boards via a respective fastening device. A pressure build-up of the fluid flowing through the plurality of micropumps during the use, which is cascaded due to the plurality of micropumps, is provided at a system outlet (106) of the micropump system.
