  • Device for determining a concentration of a constituent of blood in a hose line
    Patent number: 8792089
    Abstract: A device for determining the concentration of a constituent of blood in a hose line, in particular in the hose line of an extracorporeal blood circuit of an extracorporeal blood treatment apparatus, includes a clamping unit having an actuation mechanism configured to apply a clamping force such that first and second receiving elements are moved towards one another from a first position releasing the hose line into a second position clamping the hose line, in which the drive of the actuation mechanism takes place with an electric motor, and a monitoring unit configured to detect a hose line inserted into the receiving elements. A method for detecting a hose line in a clamping unit of a device for determining the concentration of a blood constituent in the hose line is also described. Automation of the measurement of the blood parameters is thus possible.
