Medical measuring device

摘要

A measuring device for non-invasive determination of at least one physiological parameter includes at least one diagnostic sensor unit to generate measuring signals, and an evaluation unit for processing of measuring signals. The diagnostic sensor unit is integrated into or connectible to the keyboard of a computer or into a mobile device of entertainment or communication technology, with the diagnostic sensor unit including: an optical measuring unit including at least one radiation source for irradiation of the examined body tissue and at least one radiation sensor for detection of the radiation scattered and/or transmitted from the body tissue, and/or an ECG unit for capturing an ECG signal via two or more ECG electrodes, and/or a temperature or heat sensor, and/or a bio-electrical impedance measuring unit.

1. A measuring device for non-invasive determination of at least one physiological parameter, said measuring device comprising:
(a) diagnostic sensor unit configured to generate measuring signals, said diagnostic sensor unit being integrated into or connectible to a computer, to a peripheral component of a computer, or to a mobile device of entertainment or communication technology, and (b) an evaluation unit comprising a computer processor configured to process the measuring signals, wherein the diagnostic sensor unit comprises: an optical measuring unit configured to generate a volume pulse signal, said optical measuring unit comprising at least two radiation sources configured to irradiate examined body tissue and at least two radiation sensors configured to detect radiation scattered by or transmitted from the examined body tissue, with the at least two radiation sensors being arranged at a different distance to a first radiation source of the at least two radiation sources, and an ECG unit configured to capture an ECG signal via two or more ECG electrodes, wherein the diagnostic sensor unit comprises at least one device selected from the group consisting of: a temperature sensor or a heat sensor, a contact pressure sensor, and a bio-electrical impedance measuring unit, and wherein the evaluation unit is configured to evaluate a chronological course of the volume pulse signal and the ECG signal to determine a corrective factor and to determine local glucose concentration from the corrective factor and the measuring signals generated via the optical measuring unit and the at least one device selected from the group.
