  • Systems and related methods of imaging and classifying cells in a blood sample
    Patent number: 10684206
    Abstract: Systems and methods for classifying blood cells in a blood sample are disclosed. A series of frames of the blood sample as it flows through a field of view of an image capture device are captured and analysed. Advantageously, the disclosed systems and methods combine the availability of morphological cell data with the convenience of a flow-through arrangement. The classification results can be used for estimating cell counts in a blood sample.

  • Capillary junction
    Patent number: 10307756
    Abstract: A microfluidic device with reduced risk of bubble formation at a capillary junction between two conduits is provided. In some embodiments, the microfluidic device comprises a supply reservoir, a first conduit and a second conduit. The first conduit is configured such that liquid flows by capillary effect from the supply reservoir into the first conduit. The second conduit is connected to the first conduit through an opening in a wall of the first conduit and is configured such that liquid flows from the first conduit to the second conduit by capillary effect. A width of the second conduit, along a direction of liquid flow in the first conduit, is greater than a depth of the second conduit and a depth of the second conduit is less than a depth of the first conduit.
