  • Publication number: 20240377337
    Abstract: An example cartridge includes a base having a channel configured to receive fluid, where the fluid includes a test sample to be tested on the cartridge, and a structure including at least part of a fluidic duct. The structure is configured to move relative to the base between a first position and a second position. In the first position, the channel and fluidic duct are aligned to create a fluidic connection between the channel and the fluidic duct and, in the second position, the channel and the fluidic duct are unaligned to block a fluidic connection between the channel and the fluidic duct.

  • Publication number: 20220018765
    Abstract: This invention relates to an optical system and method for performing turbidity assay, e.g. coagulation of blood or plasma, comprising a standard optical reference, a sample handling structure, a light source and an optical detection unit. The standard optical reference, such as a fluorophore-doped glass, provides constant optical signal under controlled optical conditions. The sample handling structure, such as a microfluidic system with reaction chamber, can be placed beneath or above the standard optical reference. During operation, the coagulating plasma/blood changes its optical absorbance and reflection properties, which results in changes in optical signal that reaches the optical reading unit. The variation of the optical signal, such as fluorescence signal indicates the kinetics of the turbidity varying process, such as plasma/blood coagulation process.

  • Patent number: 10852295
    Abstract: Analyte content in a cell free portion of a body fluid, such as blood, is optically determined without centrifugation or other preliminary steps for separating the cell free portion from the body fluid. A channel is configured for containing a flowing sample of the body fluid along an optical boundary. The channel is configured so that a cell free layer of the fluid naturally forms along the boundary of the channel which coincides with the optical boundary. A light source is directed onto the optical boundary at an angle selected to generate total reflection from the boundary and to generate an evanescent field across the boundary in the cell free layer of fluid. A light detector is configured to detect absorption of the light in the evanescent field. The light source and light detector are matched to the wavelength range of an absorption peak of the analyte being detected.
