Device for clamping a hose line for determining the concentration of a blood constituent
First Claim
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, andwherein 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.

Abstract
A device for clamping a hose line 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 with two receiving elements and an electric motor-driven actuation mechanism. Actuation mechanism is constituted such that, when a clamping force is applied, the first and second receiving element can be moved from a position releasing the hose line into a position clamping the hose line. Moreover, the device comprises an unlocking mechanism which is constituted such that, by actuating an unlocking element, the actuation mechanism in the position clamping the hose line can be decoupled from electromotive drive. Unlocking mechanism makes it possible for the receiving elements to be transferred easily and rapidly by hand from the position clamping the hose line into the position releasing the hose line.
