Abstract:
1. A device for clamping a hose line for determining a concentration of a constituent of blood in a hose line of an extracorporeal blood circuit of an extracorporeal blood treatment apparatus, comprising: a clamping unit which comprises first and second receiving elements for clamping the hose line; a measurement unit for coupling electromagnetic radiation through the hose line into the blood and measuring the electromagnetic radiation emerging through the hose line from the blood, wherein the clamping unit comprises an actuation mechanism and an electromotive drive for the actuation mechanism, wherein the actuation mechanism is constituted such that, when a clamping force is applied, the first and second receiving elements move from a position releasing the hose line into a position clamping the hose line, and wherein the clamping unit comprises an unlocking mechanism, which is constituted such that, by actuating an unlocking element, the actuation mechanism in the position clamping the hose line is decoupled from the electromotive drive, so that the receiving elements can be transferred manually from the position clamping the hose line into the position releasing the hose line.
