A blood processing apparatus includes a measurement device having at least one chamber element extending along a longitudinal axis and including a circumferential wall extending about the longitudinal axis, a bottom wall and a top wall together defining a flow chamber. The blood processing apparatus further includes a holder for the measurement device, the holder including a base having a reception opening for receiving the measurement device and a closure element movably arranged on the base for locking the measurement device in an inserted position in the reception opening. An ultrasonic sensor of the holder is arranged on the base. The ultrasonic sensor, in the inserted position of the measurement device, faces the bottom wall of the at least one chamber element, wherein the bottom wall extends transversely with respect to the longitudinal axis.

A tubing set for use in a blood processing apparatus comprises a measurement device () having at least one chamber element () for measuring a haematocrit value of a blood fluid, wherein the at least one chamber element () extends along a longitudinal axis (L) and comprises a circumferential wall () extending about the longitudinal axis (L) and encompassing a flow chamber (), the at last one chamber element () further comprising an inlet port () for allowing a flow of a blood fluid into the flow chamber () and an outlet port () for allowing a flow of a blood fluid out of the flow chamber (). The tubing set furthermore comprises an inlet-side tube section () connected to the inlet port () and an outlet-side tube section () connected to the outlet port (). Herein, the inlet port () and the outlet port () are arranged on the circumferential wall () and are displaced with respect to each other along the longitudinal axis (L). In this way a tubing set comprising a measurement device is provided which in an easy and reliable manner allows for the measuring of a haematocrit value of a blood fluid.

A blood processing apparatus () comprises a measurement device () having a first chamber element () for measuring a haematocrit value of a blood fluid, the first chamber element () comprising a first inlet port () connectable to a first reservoir container () for allowing a flow from the first reservoir container () into the first chamber element () and a first outlet port () for allowing a flow out of the first chamber element (), and the second chamber element () comprising a second inlet port () for allowing a flow into the second chamber element () and a second outlet port () connectable to a second reservoir container () for allowing a flow out of the second chamber element () towards the second reservoir container (). The blood processing apparatus furthermore comprises a first pump mechanism () for pumping a blood fluid in a flow direction (F) from the first reservoir container () towards the blood processing apparatus (), and a second pump mechanism () for pumping a blood fluid in a flow direction (F) from the blood processing apparatus () towards the second reservoir container (). Herein, the first pump mechanism () is located upstream of the first inlet port () of the first chamber element () and the second pump mechanism () is located upstream of the second inlet port () of the second chamber element (). In this way a blood processing apparatus comprising a measurement device is provided which in an easy and reliable manner allows for a measurement of in particular a haematocrit value in the incoming blood flow as well as the outgoing blood flow.

Blood processing apparatus comprising a measurement device

A centrifuge device comprises a fixed section, a drive device having a drive shaft, and a rotor mounted on the fixed section about a first rotational axis. The rotor is drivable about the first rotational axis. A transfer shaft is mounted on the rotor about a second rotational axis eccentric to the first rotational axis, the transfer shaft being coupled via a gearing with the fixed section. A centrifugal chamber is rotatable about a third rotational axis and is operatively connected to the transfer shaft. A locking device is arranged on the rotor for axially fixing the centrifugal chamber on the rotor. The locking device comprises a locking element and an actuating element, the locking element being adjustable between a locked position in which the centrifugal chamber is axially fixed with respect to the rotor and an unlocked position in which the centrifugal chamber is removable from the rotor.
