  • Patent number: 9541552
    Abstract: A blood analyzing device (100) comprises a light source (120) arranged to generate light (40) of a wavelength at which a Hb species in a hemolyzed blood sample (30) has absorbance. A detector system (130) is arranged to detect output light (50) from the sample (30) and generate a Hb signal representative of an amount of the Hb species in the sample (30) and a parasite signal representative of an amount of malaria parasites in the sample (30). A processor (140) generates a red blood cell value based on the Hb signal and generates a parasitemia value based on the parasite signal and the red blood cell value. A display (160) displays the parasitemia value representing a percentage of the red blood cells that are infected by malaria parasites.

  • Publication number: 20150055121
    Abstract: The invention discloses a blood analyzing device (100) comprising a holder (110) arranged for carrying a container (10) having a cuvette (20) containing a blood sample (30). The container (10) is positioned in the holder (110) so that a longitudinal axis (60) of the cuvette (20) is angled relative a horizontal axis (70). A light source (120) provides light (40) into the sample (30) and a detector (130) detects the output light (50) from a sub-portion of the blood sample (30). Kinetic information indicative of the change in hemoglobin concentration in a measuring volume (32, 34) is determined by a Hb processor (145) from the detected output light (50). An ESR processor (140) determines the erythrocyte sedimentation rate of the sample (30) based on the kinetic information.

  • Patent number: 8460938
    Abstract: A blood analyzing device (100) comprises a holder (110) for receiving a cuvette (20) with a blood sample (30). The device (100) induces a movement of the blood cells in the sample (30) by applying a field (230) over the cuvette (20). A detector (130) detects, based on output light from the blood sample (30) originating from a light source (120), a change in the induced movement of the cells caused by an increase in viscosity of the blood due to an aggregation and/or coagulation process. A processor (140) processes the detector reading and generates a signal representative of the hemostasis function of the tested blood.

  • 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.
