  • Patent number: 10092226
    Abstract: A mechanism for non-invasively monitoring blood characteristics of a subject is disclosed. To enable measurement of hemoglobin concentrations in a cost-effective way, a computational model is established that represents a relationship between a first variable indicative of total hemoglobin concentration and a set of variables that includes second variables indicative of light transmission through tissue and third variables indicative of concentration percentages of different hemoglobin species. In-vivo measurement signals are acquired from a subject and in-vivo values are determined for the second and third variables based on the in-vivo measurement signals. The first variable is then solved based on the in-vivo values of the second and third variables and the computational model.

  • Publication number: 20120253147
    Abstract: A calibration method for an apparatus for non-invasively monitoring blood characteristics of a subject is disclosed. The apparatus is provided with a computational model representing a relationship between in-vivo measurement signals obtained from the subject and the blood characteristics. The providing includes employing at least one tissue property variable in the computational model, in which the at least one tissue property variable is indicative of absorption and scattering characteristics of the subject's tissue. An arrangement for determining blood characteristics of a subject and a sensor for the arrangement are also disclosed.
