Claim Text:
1. A detection device for detecting at least one blood picture parameter of a blood constituent of blood in a blood vessel, comprising: a transmitter mode exciter positioned proximal to a first end of a segment of the blood vessel, wherein the transmitter mode exciter is a means for coupling a first transmission signal with a first frequency and a second transmission signal with a second frequency into the blood vessel such that the first and second transmission signals propagate within the segment of the blood vessel as a waveguide; a receiver mode exciter positioned proximal to a second end of the segment of the blood vessel at a distance from the transmitter along the length of the segment of the blood vessel parallel to a blood flow direction, wherein the receiver mode exciter is a means for receiving a first reception signal at the first frequency and a second reception signal at the second frequency from the segment of the blood vessel at the second end of the segment of the blood vessel; a loss detector configured to: a processor configured to ascertain a relaxation time constant (
