  • Publication number: 20190056314
    Abstract: A non-destructive method of estimating hematocrit (Hct) of whole blood from a dried blood sample prepared from the whole blood, the method comprising: a) determining the amount of hemoglobin derivatives comprising oxyhemoglobin, methemoglobin and hemichrome (total hemoglobin) in a dried blood sample, wherein the sum of the amounts of the hemoglobin derivatives remains constant in the dried blood sample in function of time, and b) estimating the hematocrit from the sum of the amounts of the hemoglobin derivatives, wherein the hematocrit is estimated using a calibration curve providing a correlation between hematocrit and the amount of the hemoglobin derivatives in a dried blood sample. The amount of the hemoglobin derivatives is preferably determined by measuring the reflectance, absorbance, or transmittance of the dried blood sample at the quasi-isosbestic point of the hemoglobin derivatives about 589 nm or at multiple wavelengths within the range of 450 to 750 nm.

  • Publication number: 20190000631
    Abstract: The present application relates to an assembly for a joint (1, 2, 3, 4), the joint comprising a joint implant (5, 6) between a proximal segment of a limb that is proximal to the joint and a distal segment of the limb that is distal to the joint and in which the joint is configured to allow rotation of the proximal and distal segments with respect to one another about an axis that intersects a first plane, and to inhibit rotation in the second and third plane, both perpendicular to the first plane, the assembly being for subjecting the joint at predetermined angles of the joint rotation in the second and third plane to a defined bending moment to induce a load to the implant that causes a movement of the implant in relation to the bone of the proximal or distal segments.
