  • Patent number: 7701581
    Abstract: The present invention (HBX) describes a system and device design for measuring and analysis of properties in liquids with suspensions, preferably human body fluids e.g. whole blood and in the fluid existing substances and particles. By penetrating a sample of the liquid suspension with specifically calibrated light passing through a thin well defined layer of the liquid placed in a non added cuvette where the transmitted outgoing light from a measuring area is registered in a spectrophotometer adapted for the specific light and the optic geometrical system arranged for elimination of scattered light. The registered data points in the photometer is then processed in a series of steps for corrections and calculation of the values/results of the desired parameters by use of different algorithms in the microprocessor of the device for final presentation on a display, be stored in a memory and possible communication to other information receiving unit.
