Patent ID: 11547328

Abstract:
The present invention relates to a detecting device for detecting a blood count parameter in a blood vessel. The detecting device comprises a signal generator, which is designed to generate a calibration measurement signal, wherein the calibration measurement signal comprises a superimposition of a first excitation signal and a second excitation signal, wherein the first excitation signal has a higher frequency than the second excitation signal and/or the second excitation signal is a direct signal and/or wherein the second excitation signal has a higher power than the first excitation signal; a transceiver arrangement which is designed to emit the calibration measurement signal towards the blood vessel and to receive a first system response signal in response to the emission of the calibration signal; wherein the transceiver arrangement is designed to emit a third excitation signal directed towards the blood vessel and to receive a second system response signal in response to the emission of the third excitation signal; and a processor which is designed to link the first system response signal and the second system response signal in order to obtain a measurement signal for determining the blood count parameter.
